Medication adherence in patients with type 2 diabetes mellitus treated at primary health clinics in Malaysia.

Purpose Diabetes mellitus is a growing global health problem that affects patients of all ages. Even though diabetes mellitus is recognized as a major chronic illness, adherence to antidiabetic medicines has often been found to be unsatisfactory. This study was conducted to assess adherence to medications and to identify factors that are associated with nonadherence in type 2 diabetes mellitus (T2DM) patients at Primary Health Clinics of the Ministry of Health in Malaysia. Materials and methods The cross-sectional survey was carried out among T2DM patients to assess adherence to medication in primary health clinics. Adherence was measured by using the Medication Compliance Questionnaire that consists of a total of seven questions. Other data, such as patient demographics, treatment, outcome, and comorbidities were also collected from patient medical records. Results A total of 557 patients were recruited in the study. Approximately 53% of patients in the study population were nonadherent. Logistic regression analysis was performed to predict the factors associated with nonadherence. Variables associated with nonadherence were age, odds ratio 0.967 (95% confidence interval [CI]: 0.948–0.986); medication knowledge, odds ratio 0.965 (95% CI: 0.946–0.984); and comorbidities, odds ratio 1.781 (95% CI: 1.064–2.981). Conclusion Adherence to medication in T2DM patients in the primary health clinics was found to be poor. This is a cause of concern, because nonadherence could lead to a worsening of disease. Improving medication knowledge by paying particular attention to different age groups and patients with comorbidities could help improve adherence.

The aim of the present study was to determine the status of glycemic control and identify factors associated with good glycemic control among diabetic patients treated at primary health clinics.

How payment scheme affects patients' adherence to medications? A systematic review

Background A previous systematic review reported that increase in patients’ medication cost-sharing reduced patients’ adherence to medication. However, a study among patients with medication subsidies who received medication at no cost found that medication nonadherence was also high. To our knowledge, no study has evaluated the influence of different medication payment schemes on patients’ medication adherence. Objective This study aims to review research reporting the influence of payment schemes and their association with patients’ medication adherence behavior. Methods This study was conducted using systematic review of published articles. Relevant published articles were located through three electronic databases Medline, ProQuest Medical Library, and ScienceDirect since inception to February 2015. Included articles were then reviewed and summarized narratively. Results Of the total of 2,683 articles located, 21 were included in the final analysis. There were four types of medication payment schemes reported in the included studies: 1) out-of-pocket expenditure or copayments; 2) drug coverage or insurance benefit; 3) prescription cap; and 4) medication subsidies. Our review found that patients with “lower self-paying constraint” were more likely to adhere to their medication (adherence rate ranged between 28.5% and 94.3%). Surprisingly, the adherence rate among patients who received medication as fully subsidized was similar (rate between 34% and 84.6%) as that of other payment schemes. The studies that evaluated patients with fully subsidized payment scheme found that the medication adherence was poor among patients with nonsevere illness. Conclusion Although medication adherence was improved with the reduction of cost-sharing such as lower copayment, higher drug coverage, and prescription cap, patients with full-medication subsidies payment scheme (received medication at no cost) were also found to have poor adherence to their medication. Future studies comparing factors that may influence patients’ adherence to medication among patients who received medication subsidies should be done to develop strategies to overcome medication nonadherence.

The influence of cultural and religious orientations on social support and its potential impact on medication adherence.

Purpose Social support can positively influence patients’ health outcomes through a number of mechanisms, such as increases in patients’ adherence to medication. Although there have been studies on the influence of social support on medication adherence, these studies were conducted in Western settings, not in Asian settings where cultural and religious orientations may be different. The objective of this study was to assess the effects of cultural orientation and religiosity on social support and its relation to patients’ medication adherence. Methods This was a cross-sectional study of patients with chronic diseases in two tertiary hospitals in Selangor, Malaysia. Patients who agreed to participate in the study were asked to answer questions in the following areas: 1) perceived group and higher authority cultural orientations; 2) religiosity: organizational and non-organizational religious activities, and intrinsic religiosity; 3) perceived social support; and 4) self-reported medication adherence. Patients’ medication adherence was modeled using multiple logistic regressions, and only variables with a P-value of <0.25 were included in the analysis. Results A total of 300 patients completed the questionnaire, with the exception of 40 participants who did not complete the cultural orientation question. The mean age of the patients was 57.6±13.5. Group cultural orientation, organizational religious activity, non-organizational religious activity, and intrinsic religiosity demonstrated significant associations with patients’ perceived social support (r=0.181, P=0.003; r=0.230, P<0.001; r=0.135, P=0.019; and r=0.156, P=0.007, respectively). In the medication adherence model, only age, duration of treatment, organizational religious activity, and disease type (human immunodeficiency virus) were found to significantly influence patients’ adherence to medications (adjusted odds ratio [OR] 1.05, P=0.002; OR 0.99, P=0.025; OR 1.19, P=0.038; and OR 9.08, P<0.05, respectively). Conclusion When examining religious practice and cultural orientation, social support was not found to have significant influence on patients’ medication adherence. Only age, duration of treatment, organizational religious activity, and disease type (human immunodeficiency virus) had significant influence on patients’ adherence.

Appropriate vancomycin use in a Malaysian tertiary hospital based on current HICPAC recommendations

INTRODUCTION Antibiotic resistance is a rapidly emerging problem. A major concern is methicillin-resistant Staphylococcus aureus (MRSA), especially in developing countries where cost-effectiveness is imperative. Restriction of vancomycin usage is necessary to reduce the emergence of vancomycin-resistant organisms. The aim of this study was to look into the appropriate use of vancomycin based on the Healthcare Infection Control Practices Advisory Committee (HICPAC) guidelines and to investigate serum levels of vancomycin. METHODOLOGY The study was performed retrospectively. Medical records of patients treated with vancomycin for the past year were identified and selected. RESULTS Overall, 118 patients were treated with vancomycin. Appropriate use of vancomycin was significantly higher than inappropriate use (p = 0.001). Approximately 85% (n = 100) of patients were given vancomycin for treatment, whereas the rest were given it for prophylaxis. Appropriate use of vancomycin was observed in 67% (n = 79) of patients. However, there was still a high rate of inappropriate vancomycin use for prophylaxis and treatment (n = 39, 33.1%). The most common reason for inappropriate use was non-neutropenic and non-line related sepsis (n = 36, 30.8%). Therapeutic drug monitoring of vancomycin was performed in 79 patients (67%). Most patients (n = 53, 67%) demonstrated sub-therapeutic levels during the first measurement. There was no significant difference between trough levels achieved with a higher (> 15 mg/kg) versus a lower dose (< 15 mg/kg). CONCLUSIONS This study demonstrates that there was still a high level of inappropriate vancomycin use, which could potentially contribute to vancomycin resistance.

A qualitative study among breast cancer patients on chemotherapy: experiences and side-effects

Purpose The objective of this study was to explore the experiences and side-effects of breast cancer patients on chemotherapy in Malaysia. Participants and methods Purposive sampling of 36 breast cancer patients who have completed chemotherapy and agreed to participate in semi-structured in-depth interviews. A constant comparative method and thematic analysis were used to analyze the interviews. Results Data were categorized into six main themes: know nothing of chemotherapy; fear of chemotherapy; patients’ beliefs in alternative treatments; symptom management; staying healthy after chemotherapy; and concerns of patients after chemotherapy. Conclusion Despite complaints about the bad experiences of their chemotherapy-induced side-effects, these patients still managed to complete the entire course of chemotherapy. Moreover, there is a need for a clinical pharmacy service in the oncology clinic setting in Malaysia in order to provide relevant information to help patients understand the chemotherapy received.

Affordability of essential medicine prices in Malaysia’s private health sector

Background The lack of price control in Malaysia has led to increased market competition, resulting in high medicine prices, notably in the private sector. This largely affects patients’ out-of-pocket expenses in the private sector. Although generic medicines are preferred due to affordability, the prices are still notably high. Methods This study compares innovator and generic medicine prices to estimate treatment affordability in the private sector. Private hospitals and community retail pharmacies were examined from 2011 to 2015. Data were collected on the basis of recommendations by the World Health Organization’s Health Action International. Results The markup of generic medicines was significantly higher than that of innovator medicines during the study period (p<0.001). While the markup of generic medicine was 31%–402% (36%–171% and 31%–402% for core and supplementary list items), that of innovator medicine was 24%–86% (28%–86% and 24%–80% for core and supplementary list items). There was no significant increase in the median price ratio for 11 selected generic medicines (from 1.8±3.9 to 2.9±8.2) (p>0.05). However, the median price ratio of the 11 innovator medicines significantly increased (from 4.9±6.1 to 11.2±20.3) (p=0.045). Affordability of all generic medicines was below the 2-day wage for treatment, with captopril (25 mg tablet) reporting the highest cost (1.1–1.7-day wages). Among innovator medicines, omeprazole (20 mg capsule; 6.2–7.0 days’ wages) reported the highest median treatment cost. Conclusion There is a need for policies to control national drug prices, to ensure medicine prices are monitored. This can help keep out-of-pocket expenses, especially in middle-income countries such as Malaysia, at a minimal in the private sector.

Qualitative exploration of the modifiable factors for medication adherence among subsidised and self-paying patients in Malaysia

BackgroundNumerous studies have evaluated the related factors of medication adherence among patients with chronic disease. However, the factors influencing medication adherence and non-adherence among subsidised patients with chronic diseases—for whom medication costs may not be a constraint—remain unexplored. Thus, this study aims to identify and compare the potential factors that may influence subsidised and non-subsidised (i.e., self-paying) patients’ adherence to medication.MethodsSubsidised and self-paying patients were identified at public and private healthcare institutions in three states of Malaysia. Patients were then purposively selected for semi-structured, face-to-face interviews according to their medication adherence status (including adherent and non-adherent patients), which was measured using the Medication Event Monitoring System (MEMS). Adherence was defined as having 80% or more for the percentage of days in which the dose regimen was executed as prescribed. The interview was conducted from January to August 2016 and during the interviews, patients were asked to provide reasons for their medication adherence or non-adherence. The patient interviews were audio recorded and transcribed verbatim. Data were analysed using thematic analysis with NVivo 11 software.ResultsThirteen subsidised and 12 self-paying patients were interviewed. The themes found among subsidised and self-paying patients were similar. The factors that influenced adherence to medication include the ‘perceived importance of quality of life’ and ‘perceived benefit or value of the medications’. A unique factor reported by patients in this study included ‘perceived value of the money spent on medications’; more specifically, patients adhered to their medications because they valued the money spent to buy/receive the medications.ConclusionMedication adherence among subsidised and self-paying patients was influenced by many factors, including a unique factor relating to their perceptions of the value of money spent on medications.

Treatment decision-making among breast cancer patients in Malaysia

Purpose This study investigated breast cancer patients’ involvement level in the treatment decision-making process and the concordance between patients’ and physician’s perspectives in decision-making. Participants and methods A cross-sectional study was conducted involving physicians and newly diagnosed breast cancer patients from three public/teaching hospitals in Malaysia. The Control Preference Scale (CPS) was administered to patients and physicians, and the Krantz Health Opinion Survey (KHOS) was completed by the patients alone. Binary logistic regression was used to determine the association between sociodemographic characteristics, the patients’ involvement in treatment decision-making, and patients’ preference for behavioral involvement and information related to their disease. Results The majority of patients preferred to share decision-making with their physicians (47.5%), while the second largest group preferred being passive (42.6%) and a small number preferred being active (9.8%). However, the physicians perceived that the majority of patients preferred active decision-making (56.9%), followed by those who desired shared decision-making (32.8%), and those who preferred passive decision-making (10.3%). The overall concordance was 26.5% (54 of 204 patient–physician dyads). The median of preference for information score and behavioral involvement score was 4 (interquartile range [IQR] =3–5) and 2 (IQR =2–3), respectively. In univariate analysis, the ethnicity and educational qualification of patients were significantly associated with the patients’ preferred role in the process of treatment decision-making and the patients’ preference for information seeking (p>0.05). However, only educational qualification (p=0.004) was significantly associated with patients’ preference for information seeking in multivariate analysis. Conclusion Physicians failed to understand patients’ perspectives and preferences in treatment decision-making. The concordance between physicians’ perception and patients’ perception was quite low as the physicians perceived that more than half of the patients were active in treatment decision-making. In actuality, more than half of patients perceived that they shared decision-making with their physicians.

Association between belief and attitude toward preference of complementary alternative medicine use

Background There is a steep increase in the consumer use of complementary alternative medicine (CAM), with many users unaware of the need to inform their health care providers. Various predictors including psychosocial factors such as beliefs and behavior have been accounted for preference toward CAM use, with varying results. Methods This study investigates the belief and attitude regarding preference toward CAM use among the Malaysian population by using a questionnaire-based, cross-sectional study. Results A large majority of the 1,009 respondents admitted to taking at least one type of CAM (n=730, 72.3%). Only 20 (1.9%) respondents were found to have negative beliefs (total score <35), 4 (0.4%) respondents had neutral beliefs (total score =35), and 985 (97.6%) respondents had positive belief toward CAM (total score >36). A total of 507 (50.2%) respondents were categorized as having a negative CAM attitude, while 502 (49.8%) respondents were categorized as having a positive CAM attitude. It was demonstrated that there was a positive correlation between belief and attitude score (ρ=0.409, P<0.001). Therefore, the higher the belief in CAM, the more positive the attitude was toward CAM. Those who were using CAM showed a stronger belief (P=0.002), with a more positive attitude (P<0.001) toward it, than those who were not using CAM. Conclusion Identifying belief regarding preference toward CAM use among the public could potentially reveal those with a higher tendency to use CAM. This is important as not everyone feels the need to reveal the use of CAM to their health care providers, which could lead to serious repercussions such as interactions and adverse effects.
