Low Medication Knowledge and Adherence to Oral Chronic Medications among Patients Attending Community Pharmacies: A Cross-Sectional Study in a Low-Income Country

Factors Affecting the Level of Adherence to Hypertension Medications: A Cross-Sectional Study Using the Hill-Bone Questionnaire

Background

The adherence to antihypertensive therapy plays a significant role in determining the clinical outcomes of hypertension. We aim to evaluate the level of adherence to antihypertensive medications among patients and to assess the effect of different sociodemographic factors on the level of adherence using the Hill-Bone scale for indirect assessment.

Methodology

In this cross-sectional study, we utilized a validated, face-to-face interview questionnaire to collect data on sociodemographic characteristics, participants' attitudes, and disease knowledge. The Hill-Bone questionnaire was employed to assess treatment adherence. The statistical analysis was conducted using SPSS version 28.0, where mean, standard deviation, and range were utilized for variability analysis.

Results

A total of 390 patients were included in this study. The sample comprised 56.9% of females and 56.4% of participants aged 60 years or older. Approximately 80% of participants were currently married, and 46.7% had a higher education level. The average Hill-Bone CHBPTS score was 21.23± 4.95 and indicated good adherence in 63.8% of participants. The findings showed that several factors were significantly associated with higher adherence rates, including older age (COR = 3.41, 95% CI = 1.10-10.54, p = 0.03), higher educational level (COR = 1.72, 95% CI = 1.05-2.83, p = 0.03), regular blood pressure monitoring (COR = 1.90, 95% CI = 1.10-3.30, p = 0.03), and knowledge about their medications (COR = 2.12, 95% CI = 1.14-3.94, p = 0.02).

Conclusion

The medication adherence within our population falls below the desired level. Enhanced counselling and further research are necessary to identify additional factors influencing adherence and develop effective strategies for promoting adherence to antihypertensive medications.

An Analysis of Medication Adherence in a Large Outpatient Population During the COVID-19 Pandemic Using a Novel Value-Based Pharmacy System

Background: Adherence to a medication regimen is defined as taking the medication as directed by the prescriber. Adherence is critical to achieve the desired therapeutic outcomes. Medication adherence has not been examined in large outpatient populations since the onset of the COVID-19 pandemic. A novel outpatient value-based pharmacy system (VPS) was used to collect adherence data from a large, outpatient population. The aim of this descriptive study was to analyze the reasons, medication classes, and diagnoses associated with nonadherence. Materials and Methods: Telepharmacist-documented adherence data from a large (n = 6,479) outpatient population that received remote consultation during the COVID-19 pandemic (August 1, 2020-November 28, 2022) were considered for this study. The adherence data were compiled within the VPS. Results: The overall rate of patients reporting at least one incident of nonadherence to their medication regimens was 21.5%. Medications used to treat hypertension, type 2 diabetes, and hyperlipidemia were least adhered to. Statins, beta-2 agonists, and corticosteroids were least adhered to. The most common reasons for nonadherence included knowledge gaps regarding therapy, forgetfulness, and side effects. Discussion: This represents the first descriptive analyses of adherence metrics in a large outpatient population during the COVID-19 pandemic. Polypharmacy, prevalence of diagnosis, and medication side effect profile may have contributed to the results observed. This study demonstrates the ability of a VPS to document key data to better inform the health care team. Elucidating adherence metrics in such populations may allow pharmacists and prescribers to identify subpopulations that require further education and management.

Prescribing and deprescribing in older people with life-limiting illnesses receiving hospice care at the end of life: A longitudinal, retrospective cohort study

BACKGROUND

Although prescribing and deprescribing practices in older people have been the subject of much research generally, there are limited data in older people at the end of life. This highlights the need for research to determine prescribing and deprescribing patterns, as a first step to facilitate guideline development for medicines optimisation in this vulnerable population.

AIMS

To examine prescribing and deprescribing patterns in older people at the end of life and to determine the prevalence of potentially inappropriate medication use.

DESIGN

A longitudinal, retrospective cohort study where medical records of eligible participants were reviewed, and data extracted. Medication appropriateness was assessed using two sets of consensus-based criteria; the STOPPFrail criteria and criteria developed by Morin et al.

SETTING/PARTICIPANTS

Decedents aged 65 years and older admitted continuously for at least 14 days before death to three inpatient hospice units across Northern Ireland, who died between 1st January and 31st December 2018, and who had a known diagnosis, known cause of death and prescription data. Unexpected/sudden deaths were excluded.

RESULTS

Polypharmacy was reported to be continued until death in 96.2% of 106 decedents (mean age of 75.6 years). Most patients received at least one potentially inappropriate medication at the end of life according to the STOPPFrail and the criteria developed by Morin et al. (57.5 and 69.8% respectively). Limited prevalence of proactive deprescribing interventions was observed.

CONCLUSIONS

In the absence of systematic rationalisation of drug treatments, a substantial proportion of older patients continued to receive potentially inappropriate medication until death.

Determinants of Medication Non-Adherence Among the Elderly with Co-Existing Hypertension and Type 2 Diabetes Mellitus in Rural Areas of Udupi District in Karnataka, India

Purpose

Medication adherence is a crucial component in the management of elderly with co-morbid chronic conditions. Hence, this study aimed to investigate the determinants of medication non-adherence among rural elderly with co-morbid chronic conditions of hypertension (HTN) and type 2 diabetes mellitus (T2DM) in India.

Patients and Methods

This cross-sectional study adopted the probability proportional to size (PPS) sampling technique to find the determinants of medication non-adherence among elderly residing in rural coverage areas of five randomly selected primary health centres (PHC) in Udupi district, Karnataka, India. A total of 360 elderly (72 samples from each cluster) who met the inclusion criteria and consented were interviewed using predesigned prevalidated and standardized or reliable tools. The data were coded and entered in SPSS version 16.0 and analyzed using both descriptive and inferential statistics.

Results

The study found that 55.6% (n=200) of rural elderly with co-morbid conditions HTN and T2DM were non-adherent to their medications and established Spearman correlation coefficient rank (r) value between undesirable person-related factors (r=-0.444); good family support (including financial support) (r=0.185); poor accessibility to healthcare facility (r=-0.209); detrimental medication-related factors including high cost of medication (r=-0.237) were found to be significant at 0.05 level of confidence (p < 0.05). Further, the study depicted that the chi-square test (χ²) was identified to be significantly associated (p<0.05) with a variable such as education, knowledge, number of illnesses and impairments, vision, memory, and physical impairments.

Conclusion

Medication adherence could be improved among rural elderly with co-morbid conditions by identifying and addressing the determinants at the earliest. Further, it is vital to identify the suitable intervention program to address these avoidable problems.

Diabetes Mellitus and Its Therapy in Brunei Darussalam - A Critical Revisit

Introduction

Diabetes is becoming an increasingly common condition across the world including Brunei Darussalam. Bruneian population, although is relatively small, represents a miniature urban community of neighbouring Southeast Asian countries as they share similar dietary and ethnicity patterns. Thus, it would be valuable to examine the findings of studies conducted among Bruneians. This study aimed to identify and review research related to the practice of patients with DM in Brunei Darussalam in order to identify associated factors influencing diabetic medication knowledge and adherence.

Methods

This narrative review analyzed literature related to DM and its therapy in Brunei Darussalam. Other issues consisting of knowledge and adherence related to DM were also explored. Databases (Scopus, PubMed, and Google Scholar) were used to search literature published up to May 2022. Search terms "diabetes mellitus", "Brunei" combined using Boolean operator were used.

Results and Discussion

Conducting appropriate studies in Brunei Darussalam can benefit the government and policymakers to implement effective measures and programmes to combat the diabetes epidemic. Despite the government's efforts, additional relevant stakeholders must be included in order to work together and engage in these initiatives in order to increase diabetes awareness, give people the power to make healthy decisions, and ultimately reduce the prevalence of diabetes in Brunei Darussalam. Patients' medication knowledge proficiency plays a main component of ensuring appropriate and safe use of medication prescribed to them.

Conclusion

Relatively poor medication knowledge and inappropriate diabetes-related practices were observed in studies conducted in Brunei Darussalam. However, no study has been done which directly measures both medication awareness and compliance among Brunei Darussalam T2DM patients. Future studies can focus on the relation between these two factors in different geographical locations of the world that are characterized by different diabetes-related practices and culture.

Medication Knowledge and Adherence in Type 2 Diabetes Mellitus Patients in Brunei Darussalam: A Pioneer Study in Brunei Darussalam

Aim: The present study measured the medication knowledge and medication adherence in patients with type 2 diabetes in Brunei Darussalam. Demographic details and diabetes knowledge were also evaluated. Methods: A cross-sectional study conducted via the administration of a structured questionnaire consisting of 4 sections via a face-to-face interview. Results: A total of 118 participants were interviewed. A majority of the participants were aged 40 years or above (106, 89.8%). The mean number of total medications that the participants were taking was 7.36 ± 2.87 and the mean number of antidiabetic medications was 2.39 ± 1.06. As for the antidiabetic therapy, the largest proportion of the participants were taking oral antidiabetic medications only (87, 73.73%). In the diabetes knowledge section of the questionnaire, more than half of the participants (63, 53.34%) scored higher than the acquired mean score. Family history, education level, and total medications taken were significantly correlated with diabetes knowledge. However, in the medication knowledge section of the questionnaire, the mean score (3.37 ± 1.38) was below the intended score for good knowledge. Medication knowledge has been significantly associated with gender, family history and total medications taken. A majority of the participants reported non-adherence (74, 62.71%) due to various reasons. In this study, those of the Malay race were significantly correlated with adherence to their medication regimen. This study also revealed that there is no significant relationship between diabetes knowledge, medication knowledge and medication adherence. Conclusions: The present study provides insights in regard to patients with type 2 diabetes in Brunei Darussalam and their knowledge towards the disease as well as their medications. Despite the lack of significance between the variables, the rate of non-adherence is still alarming. Further studies are required to better understand the barriers to non-adherence in these patients.

Medication Adherence in Chronic Older Patients: An Italian Observational Study Using Medication Adherence Report Scale (MARS-5I)

Background: the world population is aging, and the prevalence of chronic diseases is increasing. Chronic diseases affect the quality of life of patients and contribute toward increased healthcare costs if patients do not adhere to treatment. This study defines the medication adherence levels of patients with chronic diseases. Methods: an observational cross-sectional study was carried out. Patients aged 65 years and older with chronic diseases were included in this study. The medication adherence report scale was used. Results: overall, 98 patients aged 65 years and older were included. The mean age of responders was 78.65 years. Study population: 71.43% were always adherent; 9.79% often adherent; 14.89% sometimes adherent; 3.87% rarely adherent; and 1% never adherent. The internal consistency of the MARS-5I was good: Cronbach’s alfa value of 0.77. Conclusions: the MARS-5I is an effective self-report instrument to measure the medication adherence of patients. However, further studies are needed to explore factors affecting medication adherence to avoid clinical consequences for patients and high healthcare costs for healthcare facilities. Healthcare communication could be improved to ensure better transitional care.

An exploratory study of outpatient medication knowledge and satisfaction with medication counselling at selected hospital pharmacies in Northwestern Nigeria

Background

Medication counselling is an important activity that improves patient therapeutic outcomes. After this activity has been carried out, patients should be satisfied with counselling, and possess adequate knowledge about their medications.

Objectives

To describe outpatient/caregiver medication knowledge and satisfaction with medication counselling at the main outpatient pharmacies of eight public secondary and tertiary hospitals located in two states in Northwestern Nigeria.

Methods

Exit interviews were conducted from December 2019 to March 2020 with randomly sampled patients/caregivers who had just been dispensed one or more prescription medications from the main pharmacies of the hospitals. The questionnaire used contained 31 questions in three sections. The first section collected demographic information. The second section assessed respondents’ experiences and overall satisfaction with the counselling they had received. The last section evaluated respondents’ knowledge of one randomly selected prescription medication that had been dispensed to them. Data collected were coded and analyzed to generate descriptive statistics. To explore associations between respondent characteristics and overall satisfaction, non-parametric tests were used, and statistical significance set at p<0.05.

Results

A total of 684 patients/caregivers were interviewed. Majority of respondents agreed that the time spent (97.1%) and quantity of information (99.1%) provided during counselling was adequate. However, over 60% of them also agreed that dispensers did not assess their understanding of information provided or invite them to ask questions. Despite this, their average overall satisfaction with counselling on a 10-point scale was 8.6 ± 1.6. Over 90% of them also correctly identified the routes and frequency of administration of the prescribed medication selected for the knowledge assessment. Although, more than 60% of respondents did not know the duration of therapy or names of these medications.

Conclusion

Respondents’ satisfaction with medication counselling was fairly high even though they did not seem to know much about their medication.

Evaluation of medication adherence among patients with chronic diseases in Saudi Arabia

BACKGROUND

Medication adherence in chronic diseases patients is a worldwide concern. Not achieving the goal of treatments because of non-adherence will lead to more complications and eventually may lead to death. In Saudi Arabia, we have insufficient data for interpretation. Hence, this study aims to have a better perspective at the number of the non-adherent patients with chronic diseases to their medications and its associated factors.

MATERIAL AND METHOD

Cross-sectional quantitative study was conducted among chronic diseases patients living in Saudi Arabia throughout social media and hospital visits from August 2018 to April 2019. A three-section questionnaire consists of patient's health, medications and adherence characteristics. Adherence to Refills and Medication Scale (ARMS) was used to identify the level of adherence among chronic diseases patients. Univariate descriptive statistics and independent sample t-test with one-way ANOVA were used as bivariate analysis. Finally, significant predictors of medical adherence with adjusted coefficient were determined by multivariable linear regression.

RESULTS

A total of 385 patients were included in the analysis for the current study. Overall, 96.62% (n = 372) were non-adherent to their medications according to ARMS scale. Multiple linear regression model found types of co-morbidities, medication dosage form and dosage regimen to be independent predictors of medical adherence.

CONCLUSION

Medication adherence is alarmingly low among chronic disease patients in Saudi Arabia. There is a clear need for in-depth understanding for barriers. It is therefore important to conduct a qualitative study. What's known Medication adherence is a critical factor in treatment success. Low adherence to the medication is a common problem among chronic disease patients. Moreover, the majority of the studies in Saudi Arabia showed low adherence rate, and it focused in one single chronic disease only despite that patient may have more. What's new Most patients had more than one single chronic disease, so this study aims to take a snapshot to capture the adherence rate among patients who are suffering from chronic disease Saudi Arabia and its associated factors. This can help in understanding medication adherence behavior in clinical practice.

Adherence to antihypertensive medications and associated factors among hypertensive patients in Ethiopia: Systematic review and meta-analysis

The foundation of controlling hypertension is adherence to antihypertensive medication adherence. This systematic review and meta-analysis aimed to assess the magnitude and associated factors of adherence to antihypertensive medication among adult hypertensive patients in Ethiopia. A comprehensible bibliographic searching was conducted from PubMed, EMBASE, Scopus, and Web of Science core collection. All published and unpublished studies that had been accessible before 31 May 2020, and written in English were eligible. Joanna Briggs Institute assessment tool was used to evaluate the quality of the findings of the included studies. Stata software 16.0 was used to analyze the data. Study-specific estimates were pooled to determine the overall prevalence estimate across studies using a random-effects meta-analysis model. Publication bias and heterogeneity were checked. Fourteen studies with a total of 4938 hypertensive patients were included in the final systematic review and meta-analysis. The pooled prevalence of medication adherence among hypertensive patients in Ethiopia was 65.41% (95% confidence interval: 58.91-71.91). Sub-group analysis shown that the pooled prevalence of medication adherence was the highest (69.07%, 95% confidence interval: 57.83-80.31, I ² = 93.51) among studies using questionnaire technique whereas the lowest in Morisky Medication Adherence Scale eight-items (60.66%, 95% confidence interval: 48.92-72.40, I ² = 97.16). Moreover, medication adherence was associated with the presence of comorbidities (pooled odds ratio = 0.23, 95% confidence interval: 0.07-0.38, p = 0.030, I ² = 54.9%) and knowledge about the disease and its management (pooled odds ratio = 2.98, 95% confidence interval: 1.72-4.24, p = 0.04, I ² = 55.55%) but not with place of residence (pooled odds ratio = 1.22, 95% confidence interval: 0.51-1.93, p = 0.00, I ² = 76.9%). Despite a lack of uniformity among included studies, adherence to antihypertensive medication among the hypertensive population in Ethiopia was moderate. The presence of comorbidities and/or complications reduced the odds of adherence whereas having good knowledge about the disease increased chance of medication adherence among hypertensive patients.

Exit-Knowledge About Dispensed Medications and Associated Factors Among Patients Attending the Outpatient Pharmacy of Ambo General Hospital, Western Ethiopia

BACKGROUND

Insufficient knowledge of patients about their dispensed medications may result in inappropriate use of medication which can lead to treatment failure and poor therapeutic outcome.

PURPOSE

This study aimed to determine the exit-knowledge level and its determinants among patients attending outpatient pharmacy of the Ambo General Hospital.

PATIENTS AND METHODS

Hospital-based cross-sectional study was conducted on 400 study participants who visited the outpatient pharmacy in Ambo General Hospital from October to December 2019. Face-to-face interview was conducted using structured questionnaires to assess the exit-knowledge of the patients about their dispensed medication at the pharmacy exit. A binary logistic regression was employed to determine factors associated with the exit-knowledge. The association was statistically significant at 95% of confidence interval with a p-value less than 0.05.

RESULTS

A total of 400 patients participated in the study with a 100% response rate. Of the total, 222 (55.5%) patients had sufficient exit-knowledge about their dispensed medication. Patients in the age group of 19-29 (AOR=3.1; 95% CI (1.7-5.6) and 49 -59 (AOR = 3.7; 95% CI (2.3-6.0)) had greater exit-knowledge than the elderly participants (>60 years). Participants who reported the comfort of the waiting area was not suitable had lower odds of sufficient exit-knowledge (AOR= 0.7; 95% CI (0.2-3.0)) in comparison to those who reported a suitable waiting area. Lower odds of sufficient exit-knowledge (AOR=0.4; 95% CI (0.3-0.7)) was determined among those who responded fairly clarity of the dispensers guidance in comparison with those reported clear guidance. The gender and the residence of the participants were also had a significant association with the exit-knowledge level.

CONCLUSION

Modest number of the patients had sufficient exit-knowledge of their dispensed medication. Age, gender, residence, perceived comfort of the waiting area and perceived clarity of the pharmacists' guidances were significantly associated with the exit-knowledge.

Adherence to Antidiabetic Medications among Women with Gestational Diabetes

BACKGROUND

Optimal adherence to prescribed medications in women with gestational diabetes is relevant for perinatal outcomes.

OBJECTIVE

To summarize available information on the prevalence and factors contributing to medication adherence in women with gestational diabetes from the biological and psychosocial perspectives.

METHODS

A literature search on adherence in gestational diabetes was conducted in PubMed/MEDLINE, CINAHL, Scopus, and the Directory of Open Access Journals for studies published on the topic. The Arksey and O'Malley framework for scoping reviews was used to explore and summarize the evidence.

RESULTS

A total of 2395 studies were retrieved of which 13 fully met the eligibility criteria. The studies were reported in Zimbabwe (n = 5), Iran (n = 1), Mexico (n = 1), South India (n = 1), the United States of America (n = 4), and one multinational study covering Australia, Europe, North and South America. The main types of antidiabetic medications used were insulin (n = 6), metformin (n = 4), and glyburide (n = 2). The prevalence of adherence ranged from 35.6% to 97%, with the assessment tool being self-report measures (n = 8). The main factors associated with nonadherence included worsening pregnancy symptoms, side effects of medications, perceived risks, mental health symptoms, poor social support, and socioeconomic status. Recommendations that evolved from the studies to improve adherence included education, counselling, improved support networks, and social interventions, while the main reported interventional study employed continuous education on the impact of adherence on perinatal outcomes.

CONCLUSION

Medication nonadherence in gestational diabetes seems to be influenced by multiple factors with some educational interventions positively impacting adherence behaviours. Thus, future research in women with gestational diabetes could consider interventions from a multifactorial perspective to improve therapeutic outcomes.

Knowledge on Dispensed Medications and Its Determinants Among Patients Attending Outpatient Pharmacy at Chencha Primary Level Hospital, Southwest Ethiopia

Background

According to World Health Organization (WHO) drug use indicators manual, the patients' knowledge on dispensed medication is a crucial patient care indicator. There is a dearth of studies about patients' knowledge of dispensed medication at the primary health care facility. The objective of this study was to assess the knowledge of dispensed medication and associated factors among patients attending in the outpatient pharmacy of Chencha primary level hospital, Southwest Ethiopia.

Methods

A facility-based cross-sectional study was employed among 403 patients attending in the outpatient pharmacy of Chencha primary level hospital. The data collection techniques were observation of dispensing process and face-to-face interview by using WHO patient care indicators and a structured questionnaire, respectively. Descriptive statistics, univariable and multivariable logistic regression were determined using the SPSS version 20.

Results

A total of 403 patients participated which make the response rate 100%. Fifty-three (13.2%) patients had adequate knowledge on dispensed medication. The findings of multivariable logistic regression indicated that tertiary levels of education (AOR = 3.87; 95% CI [1.25, 11.96]), being private employee (AOR = 10.98; 95% CI [3.25, 37.04]), having severe perception of illness (AOR =3.77; 95% CI [1.43, 9.94]), having three or more visits (AOR =3.20; 95% CI [1.21, 8.44]) and being counseled by pharmacist (AOR = 10.02; 95% CI [4.45, 22.56]) significantly increased the odds of having a "adequate knowledge of medicines."

Conclusion

This study showed inadequate level of knowledge of dispensed medicine among patients attending in outpatient pharmacy of Chencha primary level hospital. Patient education, employment status, number of visits, perception of illness, dispenser qualification and experience were the factors for knowledge of dispensed medicine. Dispensers need into account patients' perception of their illness of illness and frequency of visits during counseling.

Paradigm shift of drug information centers during the COVID-19 pandemic

The novel coronavirus disease 2019 (COVID-19) pandemic is a major global threat affecting millions of lives throughout the world physically and psychologically. With the asymptomatic presentation of COVID-19 in many patients and the similarity of its symptoms with the common cold and influenza, the need for accurate information on the disease is very important for its identification and proper management. Accurate information on the disease, its prevention and treatment can be disseminated through drug information centers (DICs). DICs are usually staffed by pharmacists and/or clinical pharmacists/pharmacologists. DICs are a reliable source of current and unbiased information on COVID-19 and its associated complications, including management options for healthcare professionals and the public. In addition to health and drug information, pharmacists working in the DICs can be involved in the management of the patients' health by providing information on home care and safety, medication management of patients with chronic comorbid illnesses, and psychological advice. This article explores the possible additional roles DICs can play, besides providing drug information within the hospital or in the community.

Exit-Knowledge About Dispensed Medications and Associated Factors Among Ambulatory Patients Attending Ayder Comprehensive Specialized Hospital, Mekelle, Ethiopia

BACKGROUND

Optimizing exit-knowledge of ambulatory patients is a major professional responsibility of pharmacists to reassure safe and cost-effective medicines use. The study assessed the exit-knowledge of ambulatory patients on their dispensed medications and associated factors.

PATIENTS AND METHODS

Institutional-based cross-sectional study was conducted among ambulatory patients who visited the outpatient pharmacy of Ayder Comprehensive Specialized Hospital (ACSH) from December 2019 to February 2020. Data were entered, cleaned, and analyzed using SPSS version 20. Binary logistic regression was employed to determine factors associated with exit-knowledge on their dispensed medications. At a 95% confidence interval (CI), p≤0.05 was considered statistically significant.

RESULTS

The study analyzed 400 patients; more than half of the participants were males (55.5%). The mean age of the participants was 41.3 years (mean ± standard deviation (SD), ±13). Less than half of the patients did not recall the name (44.5%) and major side effects (31.2%) of each medication. Furthermore, the overall sufficient knowledge was found to be 81%. Patients with single marital status were 4.454 times to have sufficient exit-knowledge of their dispensed medications than widowed (p=0.050) participants. Besides, patients who responded neutral clarity of pharmacist instruction had 4.745 times sufficient exit-knowledge than those who responded not clear (p=0.049). On the other hand, participants who got "enough" (p<0.0001) and "not enough" (p=0.006) information from the pharmacist were found to have a positive association with sufficient exit-knowledge than those who responded "I do not know".

CONCLUSION

The majority of patients had sufficient exit-knowledge of their dispensed medications. Martially single, neutral clarity of pharmacist's instructions and adequacy of the information delivered by the pharmacist were positively associated with participants' exit-knowledge of their dispensed medications. Hence, conducting a multicenter study, we recommend pharmacists to counsel their patients to underpin patients' knowledge of their dispensed medications.
