ABSTRACT
This study examined the effectiveness of VoxQR (Voice-powered QR codes) in enhancing knowledge and
medication adherence among geriatric hypertensive patients in Koronadal City, where nonadherence to
antihypertensive medication is a common issue due to cognitive decline and difficulty understanding treatment
regimens. A quasi-experimental design was employed, and patients aged 60 and above were selected using
purposive sampling. Data were gathered using a validated questionnaire that measured adherence and knowledge
before and after the intervention. Results showed notable improvements, including a shift in medication
adherence from moderate-low to moderate high levels, increased understanding of medication purpose, dosage,
and timing. These findings indicate that VoxQR significantly enhanced medication adherence and knowledge,
suggesting that voice-based QR technology is a practical and accessible tool for supporting chronic disease
management in older adults.
Keywords: VoxQR, medication adherence, knowledge, geriatric hypertension, quasi experimental.
INTRODUCTION
Background of the Study
Medication adherence among elderly hypertensive patients is considered a public health concern, this is given
the incidence of hypertension increasing in most older adults. Studies on nonadherence have linked it to health
complications arising from it such as heightened risks of cardiovascular events and other hospital admissions. It
has been reported by research that in elderly patients, adherence is pretty low-20% to 50% on average
(Yazdanpanah et al., 2019; Saqlain et al., 2019). Contributing factors to this dilemma are cognitive decline,
complex drug regimens, and poor health literacy. Inadequate communication regarding prescription information
makes matters worse, so there is a pressing need for interventions that may be tailored to help in improving
adherence in such vulnerable populations.
The issues involving adherence to medication in the Philippines are both internal and national. Socioeconomic
status contributed much to this issue because a significant number of elderly patients find themselves in financial
situations where they cannot afford to pay for medications (Gutierrez & Sakulbumrungsil, 2021). Furthermore,
cultural beliefs and misconceptions about hypertension and its treatment are a major barrier to adherence to
medication. A systematic review indicated that Filipino elderly patients have lower health literacy, which
markedly impacts their understanding of the treatment regimen (Mohajer, 2019; Gavrilova et al., 2019). These
barriers should be implemented with educational programs being culturally sensitive and specific in the needs
of elderly patients in the Philippines to efficiently improve medication adherence.
Though previous studies have already been done to identify medication adherence among hypertensive patients,
still, significant gaps remain in understanding specific factors influencing adherence within the Filipino geriatric
population. While there are numerous studies that have identified several determinants of medication adherence
around the world, including mental health problems and socioeconomic factors (Poulter et al., 2020;
Uchmanowicz et al., 2019), there is a dearth of localized studies that focus on the interaction of these factors in
the Filipino elderly patient. Moreover, current literature seldom takes into consideration the effect of culturally

unique beliefs and practices which can determine compliance-related behaviors (Pan et al., 2019; Sanati et al.,
2020). Redress of the above will form the imperative step towards crafting interventions especially relevant for
such a population that addresses individual concerns while improving outcomes for overall health of older
hypertensives in the Philippines.
The urgency with this study is due to a high prevalence of hypertension in older Filipinos and current data
indicating that this rate stands at about 69.1% among aged people (Abalos et al., 2024). Notably, although most
aged people with hypertension understand the condition, only close to 61.6% recognize the 4 condition, hence
untreated (Abalos et al., 2024). This calls for appropriate interventions that target and address the awareness and
adherences among the aged populace. Other indirect benefits of this study are going to be elderly hypertensive
patients who will be benefited by better support for controlling their condition and healthcare professionals who
can use the information available to design culturally appropriate programs for education. Policymakers can also
use insight from this study to shape public health initiatives focused on hypertension management in older adults,
which will lead towards better health outcomes and saving healthcare costs related to the hypertension
complications.
The researcher will then ensure that results are published through different means to impact a larger population.
The researcher will initially prepare results for publication in peer-reviewed journals dealing with geriatric
medicine and public health so that insights gained would be contributed to the overall academic discourse on
medication adherence. Results will be presented to healthcare professionals and policymakers actively working
in the management of hypertension at local and international conferences. The study also intends to collaborate
with local healthcare institutions in preparing training modules based on findings that could be applied in
community health programs.
This study's primary goal is to create VoxQR (Voice-powered QR codes) to enhance knowledge and medication
adherence for geriatric hypertensive patients in Koronadal City. By leveraging this innovative technology, the
study aims to provide elderly patients with accessible and comprehensible medication information, thereby
improving their understanding and management of their treatment regimens.
REVIEW OF RELATED LITERATURE
Knowledge in Medication
Vreeland et al. (2022) pointed out that a large number of elderly Filipinos have little understanding of the
functions, dosages, and possible adverse effects of their medications. With the complexity of treatment plans
frequently recommended for treating hypertension, this ignorance can result in drug mistakes and adverse health
outcomes. According to the study, older people typically understand their medical issues, but they frequently
don't fully understand the pharmacological treatments that are available to them. Additionally, Vreeland et al.
stress the necessity of improved communication between senior citizens and healthcare professionals, especially
pharmacists. The findings suggest that many older adults do not fully utilize pharmacists as a resource for
medication-related inquiries due to a lack of awareness about the pharmacists' role in patient education and
counseling. This disconnect can hinder effective medication management and adherence.
Many people, even older persons, have misconceptions regarding how to use antibiotics appropriately, according
to Vidad et al. (2022). For example, a sizable portion of respondents did not know the proper indications for
antibiotic therapy or the possible repercussions of abuse. Given that older persons commonly use antibiotics to
treat a variety of medical conditions, this ignorance is especially worrisome since they might not completely
appreciate the significance of following recommended regimens or the dangers of self-medication. They contend
that doctors and pharmacists, among other healthcare professionals, are essential in teaching patients about the
appropriate use of antibiotics, possible adverse effects, and the significance of finishing recommended courses
of treatment.
The assessment of medication errors among in-patients in the pulmonary medicine service of a tertiary
government hospital raises serious questions about the effectiveness and safety of drug administration, especially
for elderly patients in the Philippines, according to Abunales et al. (2024). According to the study, agerelated
physiological changes, polypharmacy, and cognitive impairment might make it difficult for older persons to
Page 4092

properly manage their prescriptions, making them especially susceptible to medication errors. The authors also
discovered that the processes of prescription, administration, and recording were linked to a significant
proportion of pharmaceutical errors. The widespread practice of polypharmacy, in which several medications
are provided at the same time, increases the dangers for elderly people.
According to Giron and Cortes-Maramba (2020), the appropriateness of medication prescribing in hospitalized
older adults in the Philippines is a pressing concern, particularly regarding the prevalence of medication errors.
The study highlights that older patients are often at a higher risk for medication-related issues due to factors
such as polypharmacy, age-related physiological changes, and cognitive impairments. These factors not only
complicate their treatment regimen but also increase the likelihood of adverse drug events. Giron and
CortesMaramba emphasize that medication errors among older adults can stem from several sources, including
inadequate communication between healthcare providers and patients, insufficient patient education regarding
medication use, and the complexities associated with managing multiple prescriptions. Many elderly patients
may not fully understand their medication regimens or the importance of adherence, which can result in missed
doses or incorrect usage.
Perez (2022) asserted that improving older persons' pharmaceutical knowledge, especially when it comes to
treating chronic illnesses like hypertension, requires the inclusion of geriatric content in entry-level physical
therapy courses in the Philippines. The study highlighted that the need for healthcare professionals, particularly
physical therapists, to be knowledgeable about geriatric care and drug management is growing as the number of
aged people continues to rise. According to the research, a large number of elderly people in the Philippines
struggle with their medicine knowledge, which might result in mistakes and negative health consequences. Due
to polypharmacy, older patients frequently have complicated drug schedules, therefore it's critical that they
comprehend the functions, dosages, and possible adverse effects of their drugs.
Geriatric hypertensive patients in the Philippines
According to Abalos et al. (2024), the high prevalence of hypertension among older persons in the Philippines,
along with inadequate levels of awareness, treatment, and management is a serious public health concern.
Hypertension affected about 69.1% of older Filipinos; however, only 61.6% of those who have the ailment are
aware of it, and a startling 51.5% do not receive treatment. This disparity in treatment and knowledge draws
attention to important obstacles that support the ongoing problem of uncontrolled blood pressure in this
population. The study also highlights the critical need for focused public health initiatives to raise older
individuals' knowledge and treatment compliance. Despite existing government programs aimed at addressing
hypertension, the authors advocate for enhanced efforts to engage older Filipinos in these initiatives to ensure
better health outcomes.
The evaluation of patient knowledge regarding traditional cardiac drugs and herbal items among elderly patients
living in the community in the Philippines revealed notable knowledge gaps that may affect medication
adherence and general health outcomes (Jazul et al., 2021). According to the survey, a lot of older persons use
both prescription drugs and herbal therapies, but they frequently don't know enough about them. This ignorance
may result in pharmaceutical mistakes, inefficient treatment plans, and negative health outcomes. The results
showed that although some patients knew what their prescribed drugs were for, many had trouble explaining
their uses, dosages, and possible adverse effects. Furthermore, the study found that confusion often arose from
the concurrent use of herbal products, which patients believed to be safe and effective without fully
understanding their interactions with conventional medications.
The characteristics linked to medication adherence among hypertensive patients in the Philippines provide
important insights into the difficulties older persons encounter in treating their hypertension, claim Gutierrez
and Sakulbumrungsil (2021). The significance of enhancing patient-provider relationships and healthcare
accessibility is one of the writers' main recommendations. They discovered that patients were substantially more
likely to follow their prescription regimens if they reported having better access to healthcare services and having
a good rapport with their healthcare providers. This implies that better adherence rates can result from increased
trust and communication between patients and medical staff. This is especially important for older persons who
can encounter extra obstacles like complicated prescription schedules or cognitive deterioration.

The current state of adult hypertension care and therapy in the Philippines, according to Rosa et al. (2024),
reveals important obstacles that lead to the high prevalence and poor control rates of this illness. The report
highlights that, with only roughly 27% of hypertensive people maintaining sufficient blood pressure control and
almost half of them being ignorant of their disease, hypertension continues to rank among the nation's major
causes of morbidity and mortality. According to Rosa et al., better public health initiatives designed especially
for senior citizens are desperately needed. In addition to educating patients about hypertension, they support
improved awareness initiatives that promote consistent drug adherence and routine monitoring.
According to Sison, Cawed-Mende, and Oliva (2021), the prevalence, awareness, and treatment profile of adult
Filipino hypertensive individuals reveal critical insights into the management of hypertension in the Philippines.
The authors reported that awareness of hypertension among affected individuals is alarmingly low, with many
not recognizing the importance of regular blood pressure monitoring and management. This lack of awareness
contributes to poor treatment outcomes, as individuals may not seek medical advice or adhere to prescribed
antihypertensive therapies. Furthermore, the study indicated that even among those diagnosed with hypertension,
treatment adherence is often suboptimal due to various factors, including limited access to healthcare services,
financial constraints, and a lack of education regarding the condition.
According to Yazdanpanah et al. (2019), enhancing medication adherence among geriatric hypertensive patients
through educational programs based on the Health Belief Model (HBM) can significantly improve health
outcomes in this vulnerable population. The study highlights that older adults often struggle with medication
adherence due to various factors, including a lack of understanding about their condition, the importance of their
medications, and the potential consequences of non-adherence. The findings from the study indicated that
participants who received education based on the HBM showed significant improvements in their medication
adherence compared to those who did not receive such training. This suggests that when older adults are made
aware of their susceptibility to health issues related to hypertension and understand the serious implications of
non-adherence, they are more likely to follow their prescribed treatment plans.
Suhat et al. (2022) emphasize that older adults often face unique challenges related to hypertension management,
including cognitive decline, polypharmacy, and a lack of understanding about their medications. The HBM
posits that individuals' perceptions of their susceptibility to a health issue, the severity of that issue, the benefits
of taking action, and the barriers to taking action all play critical roles in determining their health behaviors. In
the context of geriatric patients with hypertension, these perceptions can directly impact their willingness and
ability to adhere to medication regimens. Suhat et al. found that older adults who perceived themselves as
susceptible to the complications of hypertension and recognized the severity of their condition were more likely
to adhere to their medications. Conversely, those who did not understand the risks associated with untreated
hypertension or who believed that their medications would not significantly benefit them were less likely to
follow their prescribed treatment plans. This underscores the importance of effective patient education tailored
specifically for elderly individuals.
According to Oori et al. (2019), enhancing knowledge about medication adherence among geriatric patients with
hypertension is crucial for improving health outcomes in this vulnerable population. Oori et al. emphasize the
importance of knowledge as a foundational element for enhancing medication adherence. They argue that when
older adults are well-informed about their medicationssuch as understanding their purpose, potential side
effects, and the importance of adherencethey are more likely to follow their prescribed regimens. The authors
suggest that healthcare providers should implement comprehensive educational programs that not only convey
information about medications but also empower patients by improving their health literacy.
Saqlain et al. (2019) highlights the alarming rates of non-adherence among elderly hypertensive patients in
Islamabad, Pakistan, emphasizing the need for targeted interventions to improve health literacy and support
adherence. To improve medication adherence among geriatric hypertensive patients provide programs aimed at
enhancing health literacy should be developed. These could include simplified educational materials about
hypertension and its management tailored to the literacy levels of older adults. Healthcare providers should adopt
a more patient-centered approach, ensure clear communication and understand between providers and patients
regarding treatment plans. This includes using layman's terms when discussing medications and encouraging
questions from patients.

Hypertension is a prevalent condition among older adults, and effective management is crucial to prevent
complications such as stroke and heart disease. However, medication adherence remains a significant barrier to
achieving optimal blood pressure control. The study emphasizes that understanding the disease and its treatment
is essential for improving adherence rates Gavrilova et al. (2019). The study found a direct correlation between
patients' knowledge about their disease and medication therapy and their adherence levels. Patients with a better
understanding of hypertension and the importance of their medication were more likely to adhere to their
treatment regimens. This underscores the critical role of education in enhancing adherence among geriatric
patients.
Poulter et al. (2020), Medication adherence is essential for managing hypertension effectively. Poor adherence
is a significant contributor to uncontrolled blood pressure, which can lead to serious health complications,
including cardiovascular diseases and increased mortality rates. The article emphasizes that despite the
availability of effective antihypertensive medications, adherence rates remain suboptimal, with estimates
suggesting that less than 50% of patients adhere to their prescribed regimens one year after initiation of therapy.
Lohrasbi et al. (2021) found that that health literacy is a strong predictor of medication adherence among elderly
patients. Patients with higher levels of health literacy are better equipped to understand their medications,
including dosage, timing, and potential side effects, which directly influences their adherence rates. Various
demographic factors, such as age, education level, and socioeconomic status, significantly impact health literacy
and adherence. Older adults with higher educational attainment tend to have better health literacy skills, which
facilitates better understanding and management of their medications. The study also highlights the role of
psychosocial factors, including support systems and mental health status. Patients who have strong social support
networks are more likely to adhere to their medication regimens.
Conversely, those experiencing depression or anxiety may struggle with adherence due to cognitive overload or
lack of motivation.
Adherence to recommended medication regimens is crucial for the proper management of hypertension, a
condition that is common among older persons. Studies have revealed that many hypertension patients have
trouble adhering to their treatment plans, which can result in major health issues. In this process, health literacy
the capacity to find, comprehend, and apply health information is essential (Kilic, Dag, & MSc, 2020). According
to the study, those with hypertension typically had low health literacy. Their comprehension of their illness and
the significance of following prescription schedules was greatly impacted by this deficiency. Patients with lower
health literacy were less likely to understand the implications of non-adherence, which can worsen their health
problems, or the instructions for their medications.
Hypertension is a significant health concern within the African American community, where prevalence rates
are notably higher compared to other racial groups Adinkrah et al. (2020). They found that adherence to both
medication regimens and lifestyle recommendations was alarmingly low among the participants. Many
individuals reported difficulties in following their prescribed treatment plans due to various barriers, including
financial constraints, lack of access to healthcare resources, and insufficient understanding of their condition.
Paczkowska et al. (2021) found a significant correlation between patient knowledge about hypertension and
adherence to treatment regimens. Patients who demonstrated a better understanding of their condition such as
the importance of medication, potential side effects, and lifestyle changes were more likely to adhere to their
prescribed treatments. Hypertension is a prevalent condition among older adults, and effective management is
crucial to prevent serious health complications such as heart disease and stroke. Adherence to prescribed
medications and lifestyle modifications is essential for controlling blood pressure. However, studies indicate that
many patients, especially older adults, struggle with adherence due to a lack of understanding about their
condition and treatment.
Theoretical Framework
Established by Ebrahimipoiur in 2016, provided a fundamental framework for comprehending the elements
affecting medication adherence, especially in elderly patients. According to this theory, three main factors
influence a person's desire to engage in a certain action, like following a prescription schedule: attitude toward
www.rsisinternational.org

ISSN No. 2321-2705 | DOI: 10.51244/IJRSI |Volume XII Issue IX September 2025
Page 4095
the behavior, subjective norms, and perceived behavioral control. An individual's attitude indicatec how they
feel about the activity in question. For example, older patients are more likely to follow their treatment programs
if they think that taking their prescriptions as directed will improve their health. Support from friends, family,
and medical professionals can have a big impact on a geriatric patient's desire to take their prescription as
prescribed. Subjective norms are the perceived social influences that shape a person's behavior. Patients are more
likely to take their prescriptions as prescribed if they believe that their family members or caretakers expect them
to.
Social Cognitive Theory (SCT) posits a focus of emphasis on observable learning, imitation, and modeling
within the behavior change paradigm Dela Fuente, 2023). Thus, personal variables, the environment, and
behavior co-exist with each influencing the other, in turn, in some sort of reciprocal fashion. According to SCT,
humans learn behaviors not just by direct experiencing but through observation of the actions taken by others
with the latter's consequences upon them. In the context of a study, use of VoxQR technology is a model for
effective medication management. This theory is specifically relevant to the present study because it highlights
how the VoxQR intervention can enhance self-efficacy among geriatric patients by providing them immediate
access to information about their medications. Increased selfefficacy leads to improved medication adherence as
patients feel more confident in managing their health.
According to the Health Belief Model (HBM), health behavior is a function of how seriously a health problem
is taken, how vulnerable one feels to it, the rewards for adopting preventive measures, and the obstacles to their
adoption (Rentner, 2021). This model includes the following critical elements: perceived susceptibility, which
means an individual's belief of the possibility of experiencing some health problem; perceived severity, which
is a belief in the seriousness of the health issue consequences; perceived benefits, which are the benefits that are
perceived in taking a given health action; and perceived barriers, which are the obstacles perceived in
undertaking that action.
Further cues to action or external prompting stimuli and also self-efficacy which refers to the perception of a
client's ability to take an action are important components in this model. This is especially relevant for the present
study because this model clarifies how geriatric patients' beliefs about hypertension and its drugs can influence
adherence to a prescribed regimen. For example, if older patients perceive that they are more vulnerable to the
complications of hypertension and realize the seriousness of those complications, they are more likely to comply
with their medication.
Figure 1: Conceptual Framework
The conceptual paradigm represented how the VoxQR intervention facilitates the enhancement of medication
adherence for geriatric hypertensive patients. It used voice-assisted technology to help enhance the patient's
understanding and control over their medication regimen, which is quite helpful for elderly patients due to the

complexity of using text-based instructions. In this study, the attention was given to implementing VoxQR in
the clear provision of accessible information on medication through voice commands. This innovative approach
addressed the most common barriers to adherence, such as health literacy challenges and cognitive decline. The
most important outcome variable to be affected is medication adherence, which is expected to be enhanced due
to VoxQR intervention; improved medication adherence is very important to control hypertension and reduce its
complications, such as cardiac events. Improved knowledge in terms of hypertension and its management among
the patients is the other expected outcome of this intervention since the information offered will be patient-
specific to enhance the patient's comprehension about his or her medicines and, consequently, boost self-
management skills.

conducting the study, the researcher engages with the latest theories, concepts, and methodologies, enhancing
their expertise in the field.
Future Researchers: The study's results could serve as a foundation for future research exploring the use of
technology in enhancing medication adherence across different populations and health conditions.
Scope and Delimitations
The purpose of this study was to assess how well VoxQR (voice powered QR codes) improve medication
adherence in elderly hypertension patients in Koronadal City. Important clinical variables were evaluated in the
study, such as blood pressure readings before and after the VoxQR code intervention is put into place, medication
adherence rates, and patient understanding about their prescriptions. Elderly individuals 60 years of age and
older who have been diagnosed with hypertension and were now taking antihypertensive drugs will make up the
target population. The study was carried out at Koronadal City community pharmacies, where participants were
instructed on the proper use of the VoxQR code system.
Limitation of the Study
The results and generalizability of this study have been affected by several limitations. First, the sample size
might be constrained by the number of participants available in Koronadal City's community pharmacies, which
could affect the findings' statistical power. Furthermore, because individuals may exaggerate their adherence or
comprehension because of social desirability, self-reported assessments of drug adherence and knowledge may
introduce bias. Additionally, the length of the trial might not be enough to record the VoxQR code intervention's
long-term benefits on clinical outcomes and medication adherence. Finally, participants' adherence behaviors
may be influenced by outside variables such modifications to healthcare regulations or availability of medical
care throughout the study period.
Younger populations and patients with other chronic diseases were excluded in this study because it only focused
on elderly hypertension patients being treated at Koronadal City community pharmacy. Only VoxQR code
technology was used in this experiment; no other digital health tools or interventions that might improve
medication adherence were included.
Furthermore, long-term follow-up assessments were not incorporated into the study, this study evaluated short-
term outcomes pertaining to medication adherence and understanding. The research sought to maintain a focused
approach that enables a comprehensive assessment of the efficacy of the VoxQR code intervention within a
particular setting by precisely specifying these delimitations.
Definition of Terms
For further understanding, the following terms are operationally and conceptually defined:
Medication adherence. It refers to a critical component in the management of chronic diseases, particularly
hypertension, where consistent medication intake is essential for achieving optimal health outcomes and
preventing complications.
Knowledge: It refers to the understanding that geriatric hypertensive patients have regarding their medications,
including information about drug indications, dosages, side effects, and the importance of adherence. This
knowledge were assessed using a standardized questionnaire before and after the intervention.
VoxQR: It refers to a proposed mobile application by the researcher designed to help prevent medication errors
among geriatric hypertensive patients. It utilized voice-powered QR codes to provide medication reminders,
dosage instructions, and educational content related to hypertension management.

METHODOLOGY
This chapter presented the research method, the respondents of the study, sampling technique, the research
instrument, scaling and quantification of data, data gathering procedure and statistical treatment of data.
Research Design
The usefulness of VoxQR (voice-powered QR codes) in improving medication adherence and knowledge among
elderly hypertension patients in Koronadal City was investigated in this study using a quasi-experimental
research method. The goal of a quasi-experimental study design was to assess the impact of an intervention
without randomly allocating participants to treatment or control groups. Unlike actual experimental designs, it
frequently uses pre-existing groups or allows for a certain amount of non-random assignment. When
randomization was impractical or unethical, quasi-experimental methods are helpful because they enable
researchers to make causal inferences while considering potential confounding variables (Cook & Campbell,
2021).
Research Locale
The study was carried out in the South Cotabato province, specifically in the municipality of Koronadal, which
has 27 barangays split between rural and urban areas. Its GPS coordinates are 6°29'47.0" N and 124°50'35.1".
The most southern city in the Philippines is Koronadal City, which serves as the provincial capital of Mindanao's
southern portion and has the postal code 9506. There are 195,398 people living in Koronadal City as of the 2020
census, which makes up 20.03% of the province of South Cotabato's total population.
Figure 2: Map of the Philippines and Koronadal City, South Cotabato Research Participants
The participants of this study were individuals who aged 60 and older and have been diagnosed with
hypertension. These individuals were chosen through purposive sampling, ensuring they meet specific inclusion
criteria such as age, diagnosed with hypertension, willingness to participate, ability to use VoxQR technology
and no severe cognitive impairment.
In this research, purposive sampling was applied as the sampling method that will select participants who most
likely provide valuable insight into the effectiveness of VoxQR in enhancing medication adherence and
knowledge in geriatric hypertensive patients. Purposive sampling, more commonly referred to as judgmental or
selective sampling was a non-probability in which participants were chosen based on the purposes of the study
Jim (2020). Using this approach, the researcher allowed the selection of information-rich cases that will provide
an in depth understanding and nuanced perspective of the phenomenon that is under study.

Research Instrument
A three -part self-made validated questionnaire were used in the investigation. The part l included 10 items
designed to assess participants’ medication adherence. The part ll comprised 10 itens that evaluated their
knowledge related to hypertension. This portion assessed participants' knowledge of their drugs, adherence
practices, and any perceived obstacles to adhering to their prescribed regimens. All items were structured to
gather comprehensive information relevant to the study.
It was consisted of Likert scale items. A thorough evaluation of both quantitative data and qualitative insights
into the participants' experiences with medication adherence was made possible by the mix of inquiry types.
To guarantee the validity and reliability of this questionnaire, it was developed using accepted principles of
instrument design. Every item was thoughtfully designed to complement the goals of the study, guaranteeing
that it measures the relevant constructs. To further improve the effectiveness of the instrument, a pilot test was
carried out with a small group of elderly patients to clarify and improve the questions.
A letter request for content validation of Part I and Part II of the research questionnaire was sent to the three (3)
Registered Pharmacist for three years in their current position. The suggestions from these validators were
considered in the revision and finalization of the questionnaire before the final copy was reproduced.
Data Gathering Procedure
An official letter requesting permission to conduct the study were written and sent to the Mayor of Koronadal
City prior to data collection, as approved by the Department Dean. The chosen participants in the study were
interviewed in-person by the researcher.
With the use of this approach, which facilitates direct communication, the researcher was able to collect detailed
information about how well VoxQR (Voice QR codes) improve medication adherence and knowledge in elderly
hypertensive patients. To complete the survey, the participants were given 30 minutes by the researcher. After
giving the NUPs enough time to finish the questionnaire in a halfhour, the respondents' questionnaires were
gathered. Then, the gathered information was tallied, tabulated, and statistically analyzed as needed. In order to
promote truthful and objective responses, the data collection procedure guaranteed the respondents'
confidentiality and anonymity. Throughout the data gathering process, researcher adhered to stringent ethical
guidelines, protecting the participants' rights and privacy.

Scoring and Quantification
To describe the extent of various dimensions within the study, the researcher used a 4-point Likert Scale. This
scale was particularly effective for measuring attitudes, perceptions, and behaviors related to medication
adherence among geriatric hypertensive patients. The 4-point Likert scale provided four distinct response
options: 1 - Strongly Disagree, 2 - Disagree, 3 - Agree, and 4 Strongly Agree. This format obliged respondents
to express an opinion without the option of a neutral response which helped eliminate indecisiveness and
encourage more definitive answers.
The use of a 4-point scale was advantageous in this research context because it compels participants to lean
towards either agreement or disagreement, thereby providing clearer insights into their attitudes toward
medication adherence and the effectiveness of the VoxQR intervention. For example, questions may assess how
confident participants feel about their understanding of their medications or how they perceive the usefulness of
the VoxQR technology in managing their health.
Statistical Treatment
To address the study concerns, the collected data was totaled and examined. The means of the responses were
calculated, and only the most significant were highlighted in the finding’s presentation. To analyze the average
responses, the study used a 4-point rating scale to ascertain participants' degree of agreement or perception with
respect to several facets of medication adherence and knowledge improvement via the VoxQR code intervention.
A more detailed assessment of participants' attitudes was made possible by the scale, which goes from 1 (strongly
disagree) to 4 (strongly agree).
Descriptive statistics were used to examine the information gathered from the Likert scale replies. This involved
figuring out the average score for every item, which gives a general indication of how participants felt about
their understanding and adherence to their prescription both before and after using VoxQR. Furthermore,
frequency distributions were produced to show the proportion of respondents who choose each category on the
scale, which aids in spotting patterns in the sample population's opinions or habits.
It is essential to consider suitable statistical treatments because Likert scale data are frequently handled as
ordinal. When analyzing ordinal data, some researchers recommend using non-parametric tests like the Mann-
Whitney U test or Spearman's rank correlation coefficient. However, other researchers contend that parametric
tests like t-tests or ANOVA can also be used if the sample size is large enough and the distribution is normal. If
circumstances allow, parametric techniques may be applied in this study to evaluate mean score differences
between pre- and post-intervention groups.
Ethical Considerations
During the conduction of this study on the efficacy of VoxQR voice powered
QR codes in improving adherence to medication and knowledge in elderly hypertensive patients, several ethical
considerations were fundamental to ensuring research integrity and protecting participants. The researchers
ensure that all possible issues are considered and appropriately addressed. Equally important is the acquisition
of informed consent from all participants who are part of the study. The main ethical consideration is heightened
by the need for anonymity and confidentiality. All participating elderly hypertensive patients are given an
informed consent form, which allows them to check and understand the study before deciding to participate.
The information collected by VoxQR Code is sensitive and confidential, and it must be protected in accordance
with the Data Privacy Act. The Data Privacy Act requires organizations to implement technical, physical, and
administrative measures to ensure the confidentiality and safekeeping of data.
In addition, VoxQR Code also complied with specific requirements of the Data Privacy Act. For example,
researchers obtained consent from patients before collecting and processing their personal data. Researchers
must also provide patients with access to their personal data and allow them to request corrections or deletions
of their data.

Page 4101
VoxQR Code must also have policies and procedures in place to manage data breaches. Researchers document
any incidents of unauthorized access to or disclosure of personal data and report them to the relevant authorities
and affected individuals within a specified timeframe.
After compiling and obtaining all the data required for this study, the researchers destroy all data collection
documents, including the information sheet, the consent forms from the respondents, and the questionnaire
containing all their responses, to safeguard the privacy of the respondents. This guarantees that the responders'
safety and privacy are appropriately handled and managed. The utmost importance is placed on research
participants' dignity.

Table 1 shown the level of clinical indicators related to medication adherence among geriatric hypertensive
patients in in Koronadal City before the Medication Adherence VoxQR code intervention was introduced.
The strongest statement to have the highest mean was Statement 4: " I never experience difficulty remembering
when to take my hypertensive medication," with a mean of 2.67, a Moderate-High Level of adherence. This
result indicates that most of the geriatric patients with hypertension in Koronadal City already had some memory
for remembering their medication regimen prior to the VoxQR code lntervention. Such memory retention might

be due to daily habits or time routine reminders, such as taking medicine with food or in the morning. Moreover,
caregivers or family members could be having an active part in reminding the patients to use their medication,
thus supporting compliance.
Conversely, the lowest mean occurred for Statement 1: " I take my hypertension medication exactly as prescribed
by my doctor," which had a mean score of 2.24, and it fell under the Moderate-Low Level of compliance. This
result points to an even more troubling fact: even if patients do recall taking their medicine, many are not
adhering to the intended regimen in dosing, timing, or frequency. This misalignment can lead to decreased
efficacy of treatment and greater health consequences. Possible explanations for this outcome are low health
literacy, reading confusion of prescription labels, and unawareness of the consequences of non-compliance. In
addition to that, old age cognitive impairment, visual disturbances, or even the complexity of medication
directions might also impede strict compliance. Unknowingly, patients may miss doses, double doses, or
administer medicine at the incorrect times, all of which break the efficacy of therapy.
Overall mean for all clinical indicators was 2.49, reflecting a Moderate-Low Level of medication adherence
prior to VoxQR code intervention implementation. This suggests that geriatric patients are trying, but to some
extent only, to control their hypertension by taking their medications. It implies that patients' adherence to
medications is suboptimal and not consistent. It appears that current methods, either in the form of informal
routine or caregivers, are inadequate to provide regular, correct, and timely consumption of medications.
This trend in the outcomes can be attributed to a variety of reasons. Most patients who are elderly suffer from
age-related issues like forgetfulness, poor vision, and lower understanding of medical procedures. Although they
can remember that they need to take medicine, specifics like timing, dosage, and frequency tend to be issues
without adequate help tools or reminders.
This was echoed by Marengo and Barberato-Filho (2023), who highlighted the importance of medication
adherence devices being designed through contributions from older individuals. Their scoping review reported
that older patients are eager to accept the use of assistive devices to mitigate physical and cognitive limitations,
such as audio or haptic feedback devices a central tenet in the VoxQR code intervention.
Likewise, Faisal et al. (2023) emphasized the significance of smart features in medication management devices,
like voice guiding and easy-to-use interface design, that facilitate easier prescription-compliance among elderly
individuals. The application of VoxQR code is consistent with such evidence by providing an audiobased
reminder mechanism specially designed to overcome memory and literacy limitations.
Last of all, Jachimowicz et al. (2021) provided behavioral evidence concerning medication-taking behavior.
Based on their study, emphasizing the subject-specific health implications of non-compliance and incorporating
behavioral cues in other words, straightforward reminders and stable feedback can significantly enhance
compliance. That is also an argument for making use of innovative and customized instruments like VoxQR
code in encouraging compliance among older adult hypertensive patients.
After
Medication Adherence
Table 2 shown the level of medication adherence of among geriatric hypertensive patients in Koronadal City's
after the use of the Medication Adherence (VoxQR). The table quantifies the effect of the intervention on the
behavior of patients through different indicators of their medication regimen.
Highest mean score was achieved by Statement 1: "Now, I take my hypertension medication exactly as
prescribed by my doctor," with a mean score of 3.31 and was rated as having a High Level of medication
adherence. It indicates that with the introduction of VoxQR code, a very high proportion of elderly hypertensive
patients in Koronadal City started to adhere more accurately and regularly to their prescribed drug regimens.
This substantial improvement suggests that VoxQR code was a successful behavioral cue that facilitated the
habit of taking medication. Its easy and consistent visual and routine-based monitoring likely facilitated
overcoming typical barriers like forgetfulness or insufficient perceived urgency in medication regimens.

Page 4103
On the other hand, the lowest mean score was achieved in Statement 3: "I no longer skip doses because of the
VoxQR reminders," with a mean of 2.96, still at a Moderate-High Level of adherence. Although this finding
reflected overall improvement, it also shows that total eradication of skipped doses was not universally achieved.
This residual difficulty can be attributed to a variety of possible reasons. First, age-related cognitive impairment,
for example, memory loss or attention deficit, can still disrupt rigid compliance regardless of reminders. Second,
some other patients might not have integrated the VoxQR fully into their daily routines, possibly due to
unfamiliarity with the technique, physical disability (e.g., poor sight or dexterity), or limited engagement. Third,
extrinsic environmental or social factors such as unstable caregiver support, intricate medication regimens, or
even psychiatric resistance to the use of chronic medications may further account for why some doses continued
to be omitted even after the intervention.
The overall mean score across all measures in Table 2 was 3.14, which is a Moderate-High Level of adherence
after the administration of the VoxQR. This outcome suggests that the VoxQR intervention was generally
effective in improving medication adherence among elderly hypertensive patients. It offered a structured, visible,
and behaviorally engaging system that probably encouraged regular medication intake. The improvement
observed can also be attributed to the psychological advantage of self-monitoring, wherein patients tend to
adhere to their routines when they can visibly measure their progress.
The high degree of improvement in compliance can be explained by the visual and behavioral encouragement
from the VoxQR tracker. In older patients with poor memory or motivation, a visual reminder every day and
habit tracking device made taking medication a habitual activity less likely to be forgotten. In addition, repeated
use of VoxQR may have created a sense of responsibility or achievement to comply with prescriptions.
The findings corroborate Simon et al. (2021), who wrote that safe, easy solutions such as digital tools, reminders,
and structured care systems significantly improve drug compliance, especially among patients with
cardiovascular disease. The study indicates that medication adherence is not just a medical issue but a behavioral
oneaddressed effectively by interventions such as VoxQR.
Likewise, McGillicuddy et al. (2020) found that mHealth interventionsi.e., mobile-based reminders and
monitoring deviceswere associated with heightened stability and consistency of drug levels among patients.
Their research supports that technology-enabled strategies such as VoxQR minimize variability in adherence
behavior, a finding supported by the increased precision achieved in Statement 1 of the current study.
Within a systematic review conducted by Bingham et al. (2021), telehealth interventions resulted in medication
adherence to chronic conditions such as hypertension. While evidence of the efficacy of reminder-based
strategies is supported in the review, there are noted limitations especially in low tech-literate or variable device
use populations. This perhaps explained why some of the sample in the current study continued to report
occasional dose skipping, despite the intervention period.

Table 3 shown the knowledge level of Koronadal City geriatric hypertensive patients on their clinical indicators
before the Medication Adherence (VoxQR) intervention was implemented. The table contained statements that
measure patients' knowledge on the purpose, timing, and routine of their antihypertensive medication regimen.
The statement that received the highest mean was: Statement 2: "I know that the main purpose of
antihypertensive medication is to lower and maintain healthy blood pressure," having a mean of 3.07, equating
to a Moderate-High Level of knowledge. This indicated that most elderly patients have a basic knowledge of
why they are given antihypertensive medication. Knowledge of the function of medication is a key initial step
toward the formulation of a good attitude towards compliance, since patients are more apt to cooperate when
they are aware of the health advantages that accrue from accurate drug use.
Statement 3: "I know the specific time of day I am supposed to take my blood pressure medication," had the
lowest mean of 2.48 and was interpreted as a
Moderate-Low Level of knowledge. This is a difference between theoretical and practical knowledge patients
may be aware of the necessity of the medication but may not necessarily know the specific timing that is optimal.
This medication timing error can result in missed doses or erratic blood pressure control, compromising the
efficacy of treatment and putting patients at increased risk of complications.
Overall, the aggregate mean score was 2.78, which was below the Moderate-High Level of knowledge. This
suggested that, pre-VoxQR code intervention, geriatric hypertensive patients had sound rudimentary knowledge
of their condition and drug. Inconsistency in range of individual indicators, however, suggests diversity of
knowing patients know the overall intent of their medication but perhaps not implementation details like timing
and regimen composition.
The findings were consistent with the general pattern among older patients, wherein overall familiarity can be
found, but specific knowledge about procedures may not be present. This might be due to verbal-only instruction
during consultations, declining cognitive functions, or lack of written reminders. Patients might also forget exact
instructions without available and tailored support tools, even if they appreciate the drug's contribution in blood
pressure control.
These results were complemented by DeFulio and Silverman (2012), which highlighted the reinforcement and
organized support systems role in enhancing medication adherence. They discovered that patients know why
they are on drugs but tend to not consistently deliver detailed adherence without being prompted or supported
by an organized tool or protocol. That is what equates to this current study's moderate-high purpose knowledge
but moderate-low timing knowledge.
Similarly, Stern et al. (2016) proposed the use of personalized medication discharge kits to help patients manage
complex medication regimens. According to their research, even with successful discharge education, patients
do not necessarily store or adhere to timing instructions unless supported by visual or physical means
highlighting the importance of tools such as VoxQR to bridge that knowledge gap in specific areas.

After
knowledge
Table 4 presented the level of knowledge regarding hypertension medication adherence among geriatric patients
after the implementation of the VoxQR code Medication Adherence. The table presents participants' responses
to several statements that indicate their recognition and understanding of proper use of medication, timing,
and nonadherence effects.
The highest mean score was obtained in Statement 5: "Thanks to VoxQR, I am aware that missing doses of my
antihypertensive medication can lead to health complications," with a mean of 3.45, which was interpreted as a
High Level of knowledge. This means that the VoxQR code intervention successfully improved geriatric
hypertensive patients' awareness of the possible outcomes of nonadherence, i.e., the health complications
resulting from skipped doses of ordered medication. This finding supports the educational importance of the
VoxQR that was not only employed as a behavioral aid to track but also to remind patients of important health
about regular medication intake.
The lowest mean score was in Statement 3: "Using VoxQR, I am aware of the specific time of day I need to take
my blood pressure medication," with a mean of 3.13, which is still a Moderate-High Level of knowledge.
Although this is a generally positive effect, it also suggests that there are still some lingering gaps in time-related
medication knowledge. This may be due to any number of factors: the VoxQR might not have emphasized time-
of-day reminders as much as other adherence reminders, or some patients may simply continue to struggle with
incorporating fixed drug regimens into their schedule.
The overall mean score for knowledge post-implementation of the VoxQR was 3.28, which is interpreted as a
High Level of knowledge. This indicated that the intervention significantly improved patients' knowledge about
their medication and the implications of nonadherence. In addition to encouraging action, the VoxQR seems to
have supported cognitive engagement, empowering patients with actionable knowledge.
The significant overall high scores for the majority of statements suggested that VoxQR was able to convey
educational messages and reiterate patients' knowledge of medication adherence successfully. Small challenges
with time-specific memory or scheduling, however, can have contributed to the lower score on Statement 3
which can be attributed to age-related challenges with memory or insufficient attention to timing in the
intervention.
These findings were consistent with Marengo and Barberato-Filho (2023), who found that digital interventions
involving visual reminders and interactive features significantly improved elderly patients' knowledge and
awareness of medication. Their research highlighted the role of organized interventions in enhancing medication
consequence knowledge, especially among hypertensive patients.
Likewise, Faisal et al. (2023) indicated that mobile and QR code-based reminder and education systems
enhanced general and specific knowledge regarding the use of medications. They found that when elderly
patients are given easy-to-read electronic reminders, their capacity to understand dosing regimens and risks of
nonadherence significantly enhances.
In addition, Jachimowicz et al. (2021) offered proof supporting the concept that behaviorally-informed
interventions like VoxQR not only enhance behaviors but also boost cognitive awareness of health habits. In
their research, nudging through customized, low-effort prompts yielded improved long-term retention of
knowledge and healthy behavior, particularly among populations with original low levels of compliance.

and after the Medication Adherence VoxQr: Table 7 provided statistical comparison of three significant
clinical measures medication adherence, knowledge, and blood pressure monitoringprior to and subsequent to
use of the VoxQR code Medication Adherence by geriatric hypertensive patients. Results provided mean scores,
standard deviations, tvalues, degrees of freedom (df), and p-values for each measure. Statistical significance was
established using a p-value of < 0.05.

INTERNATIONAL JOURNAL OF RESEARCH AND SCIENTIFIC INNOVATION (IJRSI)
ISSN No. 2321-2705 | DOI: 10.51244/IJRSI |Volume XII Issue IX September 2025
For adherence to medication, the mean score was substantially higher at 3.14 (SD = 0.1529) post-intervention
than 2.49 (SD = 0.1719) before the intervention, t-value of 5.4251 and p-value 0.0056, indicating statistically
significant improvement. This outcome favors the efficacy of VoxQR in improving the regularity, timing, and
compliance in general with antihypertensive medication among elderly patients. The improvement is a sign of a
positive behavioral change, as the participants began complying more in accordance with their prescribed
regimens. This could be an effect of the visual and auditory reminders of VoxQR code, which introduced a
structured reminder system that patients could daily count on. This reinforcement is particularly important in
older individuals, who are vulnerable to age-related cognitive impairment, polypharmacy, and reduced caregiver
monitoring. VoxQR code most likely served not just as a passive device, but as an active behavior intervention,
simplifying medication regimens and reducing incidents of forgetfulness or indiscriminate omission. The result
emphatically attests to the value of low-tech yet habit-reforming devices in enhancing health outcomes among
high-functioning vulnerable populations.
In regards to knowledge, the same statistically significant increase was noted, with mean scores increasing from
2.78 (SD = 0.2533) pre-intervention to 3.28 (SD = 0.1199) post-intervention, with a t-value of 4.3049 and a p-
value of 0.0126. What this indicates is that not only did the VoxQR code intervention alter patient behavior, but
it improved the patients' knowledge regarding the necessity and proper use of antihypertensive medications. The
tracker can have served as an educational contact pointproviding repeated exposure to information about
medication timing, dose, and consequences of nonadherence. For older patients, who frequently struggle with
health literacy or memory recall, this kind of embedded, repeated learning is both feasible and effective. As they
interacted with the VoxQR code in the course of their daily activities, patients were presumably reminded not
only when to take their medication but also why taking it is important, creating an enhanced cognitive linkage
to their care.
In terms of blood pressure tracking, the outcome once more was a statistically significant improvement, as the
mean went up from 2.47 (SD = 0.0952) prior to intervention to 3.05 (SD = 0.2344) thereafter, backed by a t-
value of 5.1269 and a p-value of 0.0009. This means that patients became more engaged and proactive in learning
and monitoring their blood pressure after the VoxQR code usage. Although the app itself did not measure blood
pressure, frequent reminders to take medication may have boosted patients' activity with self-monitoring
behaviors. Improved compliance generally accompanies increased frequency of visits, home blood pressure
monitoring, and communication with clinicians. The result shown that once the patients understood the
importance of being compliant with their drug regimen, they also became more vigilant in observing the
effects particularly the management of blood pressure. The dramatic improvement in this domain is an
indication of transition from passive receipt of care to active engagement in disease control, a significant target
in geriatric health policies.
Generally, the findings showed that there was a statistically significant change in all the clinical parameters
monitored among geriatric hypertensive patients following the use of the Medication Adherence VoxQR code.
Medication compliance rose from a mean of 2.49 pre-intervention to 3.14 post-intervention (p = 0.0056), which
is a change from a Moderate-Low to a Moderate-High Level of compliance. Scores for knowledge rose from a
mean of 2.78 to 3.28 (p = 0.0126), which represents a change from a Moderate-High to a High Level of
knowledge about hypertension and medication. Finally, indicators of blood pressure increased from a mean of
2.47 to 3.05 (p = 0.0009), which represents a significant shift from a Moderate-Low to a Moderate-High Level
in patients' confidence and knowledge about their blood pressure control. These findings validate that the VoxQR
code intervention was successful in improving behavioral compliance, health literacy, and patient activation in
hypertension self-care.
The findings indicated that the VoxQR intervention is a valuable intervention for improving medication
compliance, health knowledge, and blood pressure awareness in geriatric patients with hypertension. It is simple,
behaviorally supported design addresses both cognitive and routine-related problems in elderly care and is
therefore an effective measure for enhancing self-management among this population.
Such findings are excellently supplemented by Poulter et al. (2020), who emphasized the need for compliance
to medication on a daily basis in order to achieve best control of blood pressure. Their study emphasized the fact
that without compliance, even the best antihypertensive medication cannot deliver results. VoxQR directly
supports this principle by inducing adherence through ease of use and accessibility.

Similarly, Siddiqui et al. (2020) found that the majority of patients diagnosed with resistant hypertension were
in fact suffering from nonadherence. Such research supports the efficacy of tools like VoxQR code in eliminating
treatment resistance assumptions and giving patients the power to stick to their treatment schedule consistently.
The dramatic elevation in the level of adherence in the present study supports this necessity for behaviorally
focused adherence tools.
In addition, the enhancements of patient knowledge and activation were complementary to results by Sartori et
al. (2020), who illustrated that digital and messaging-based health education interventions (e.g., WhatsApp)
enhanced medication adherence and knowledge in hypertensive and diabetic patients. VoxQR, though not
digital, produces a comparable effect through salient and frequent exposure to health messaging and medication
adherence reminders.

CONCLUSION
Based on the findings of the study, the researcher concluded the following:
1. Before the Medication Adherence VoxQR code was introduced, geriatric hypertensive individuals in
Koronadal City presented with inconsistent drug adherence and discrepancies in practical knowledge,
particularly timing of medication intake, which negatively impacted blood pressure control. The patients were
conscious of the danger of hypertension but were not sure about selfassessment. Following the VoxQR code
intervention, adherence, knowledge, and confidence in the control of blood pressure significantly enhanced, with
some issues in complete uptake of the tool and coping with complicated regimens persisting and an implication
that support is still needed to reinforce self-care.
2. Statistical analysis attested to the notable improvement in medication adherence, knowledge, and blood
pressure measurement in geriatric hypertensive patients after employing the Medication Adherence VoxQR
code. These findings support that the intervention was successful in improving behavioral compliance, health
literacy, and self-management and justifying its merit as a pragmatic tool in improving hypertension
management among the elderly.

RECOMMENDATIONS
Based on the findings and conclusions, the study arrived at the following recommendations:
1. The continued use of the Medication Adherence VoxQR code may encouraged for enhancing medication
compliance and self-tracking among elderly patients with hypertension. Moreover, extended support could
be offered to guide patients in dealing with difficulties associated with the application of the instrument and
adherence to complicated regimens.
2. The Medication Adherence VoxQR code may be suggested to be used in geriatric hypertensive patients since
it can immensely enhance medication adherence, understanding, and blood pressure assessment, thus overall
selfmanagement and health outcomes.

Purpose of the Study:
This study aims to evaluate the effectiveness of VoxQR (Voice-Powered QR Codes) in improving medication
adherence and enhancing knowledge of hypertension among geriatric hypertensive patients in Koronadal City.
Hypertension remains one of the leading causes of cardiovascular complications among older adults. Poor
medication adherence is a major factor contributing to uncontrolled hypertension, leading to increased healthcare
costs and reduced quality of life. By introducing VoxQR as an intervention, this study seeks to measure its

Comments and Suggestions
1.Lay out: Title in single indention only. Divide the questionnaire into 5 parts.
2.Demographic Profile is not part of the SOP but it still important to include. I added items 11-12.
3. If I may suggest to add LEVEL of SATISFACTION to assess the use of VoxQRcode. This will be part
V and post test only. There are items in the MEDICATION ADHERENCE that be deleted or be included in the
LEVEL OF SATISFACTION.
4. Give a short thank you statement after the last table.
5. Avoid jargon or medical terms, difficult for the respondents to understand. I suggest you will have a
Tagalog translation of your Consent form and Questionnaire.
