Objectives: Medication adherence to treatment recommendations has major impact on health outcomes. Numerous interventions to improve medication adherence among the patients have been studied in clinical trials, including calendar packaging and patient reminder letters. Therefore, this study is aimed to explore hypertensive patient’s perceptions towards calendar packaging and its impact on medication adherence.
Methods: A qualitative method was adopted, whereby two focus group sessions were conducted among 16 conveniently sampled hypertensive patients from a community based non-governmental organisation in the state of Penang, Malaysia. A pre validated focus group guide was constructed and used for data collection. Collected data was transcribed verbatim and analysed by thematic content analysis to identify the emerging themes.
Results: Each focus group consisted of 8 hypertensive patients. Thematic content analysis resulted into 3 major themes (knowledge and familiarity with the medicines names and their packaging; perception about the packaging and labelling of medicines; knowledge and views of calendar packaging) and each theme was further divided into 2 sub themes. Majority of the hypertensive patients were not familiar with their medication names, however they were able to identify their medications based on the appearance and packaging. Participants agreed that calendar packaging is a great intervention to increase awareness among patients about regular medicine use and increase medication adherence.
Conclusions: The study concluded that hypertensive patients relied on the packaging and labelling on the medications to identify their medications. Thus, packaging and labelling of the medications play an important role in improving medication adherence and reduce medication errors. This finding can help to enhance the drug manufacturers to pay attention on the drug packaging in order to increase medication adherence among the patients.
Objectives: Diabetes mellitus is a serious health problem. Medication adherence is a key determinant of therapeutic success in patients with diabetes mellitus. The purpose of this study was to assess medication adherence and its potential association with diabetes related knowledge in patients with type 2 diabetes mellitus.
Methods: This study was carried out at the outpatient clinics of a public sector teaching hospital in Sargodha, Pakistan. Besides demographic and disease-related questions, previously validated questionnaires, Morisky Medication Adherence Scale and Michigan diabetes knowledge test was used to assess the medication adherence and diabetes related knowledge, respectively. Descriptive statistics were used to determine the demographic and disease characteristics of the patients while Spearman rank correlation was employed to measure the association between medication adherence and knowledge.
Results: Three hundred and ninety two patients were interviewed. Out of 392 patients, 245 (62.5%) of the patients had average knowledge about diabetes while 282 (71.9 %) were categorized as poor adherent. Only 13 patients (3.3 %) were considered as good adherent in the study. The correlation coefficient between total scores of knowledge and total medication adherence score was 0.036 (p< 0.05), indicating a weak correlation between knowledge scores and adherence level.
Conclusions: Knowledge of diabetes mellitus among these patients was average; however, adherence to drug therapy was also poor. Patients’ knowledge about diabetes had positive association with medication adherence. Improving diabetes knowledge of people can result in better adherence, which may result in better control of diabetes.

Objectives: Warfarin has been used for more than 50 years as stroke prophylaxis in patients with atrial fibrillation. New oral anticoagulant, Dabigatran, was developed and shown to be safer and more efficacious compared to Warfarin due to its lower tendency of bleeding and in reducing stroke incidences. This study aims to compare the pattern of anticoagulants used and to assess their safety and efficacy by evaluating bleeding and stroke occurrences in both groups.
Methods: This is a retrospective study carried out at a hospital with hematology clinic in the state of Selangor, Malaysia. The samples of the study were patients with atrial fibrillation, prescribed with warfarin or dabigatran. Data collected includes patients’ demographics, co-morbidities, and stroke and haemorrhage events.
Results: A total of 71 patients were recruited in this study with 21, 21 and 29 patients were on Warfarin, Dabigatran 110 mg and Dabigatran 150 mg respectively. Out of 50 Dabigatran users, 36 of them are warfarin-experienced. 1 out of 21 patients on warfarin experienced stroke while none in both 110 and 150mg dabigatran group. A total of 11 (52.4%) of warfarin patients experienced bleeding with 2 of them having major bleeding whereas, only 4 (8%) out of 50 dabigatran patients experienced minor bleeding, 1 in patient who were on Dabigatran 150mg and 3 patients who were on Dabigatran 110mg.
Conclusions: The pattern of anticoagulant used for stroke prophylaxis in atrial fibrillation is slowly changing from Warfarin to Dabigatran. Evaluation of safety and efficacy profile of Warfarin shows that Warfarin requires more extensive management and monitoring in order to achieve therapeutic goals with fewer side effects. Comparison between both anticoagulants show that Dabigatran is safer and more effective compared to warfarin

Objectives: To evaluate the long-term cost-effectiveness of RMTAC (an adjunct
pharmaceutical asthma management) vs. usual physician care clinic by using decision analytic modelling method. Methods: A dynamic adherence asthma Markov
cohort model was developed. The economic evaluation was based on a lifetime
horizon and cycle length of one month, from the healthcare provider‘s (Ministry
of Health) perspective, with the outcomes assessed in cost per QALY gained and
cost per hospitalization averted. Probabilities of asthma control-adherence states
from RMTAC database, costs from national sources, utilities using standard gamble method on Malaysia’s asthma patients, and other inputs from secondary data
sources were used to inform the probabilistic model, according to gender and age
subgroups. A scenario analysis was conducted to test the structural assumption on
follow-up visits after the final treatment visit. Results: In female subgroup, RMTAC
management dominates the usual care by having 0.91 (95% CI 0.24 – 1.69) QALY
gained and 0.58 (95% CI -2.30 – 6.23) hospitalization averted, at a lower cost. For male
subgroup, the ICERs were RM10 (95% CI -RM14431 – RM8323) per QALY gained and
RM18 (95% CI -RM35790 – RM30266) per hospitalization averted. At the willingnessto-pay threshold of RM29000 per an additional QALY gained, the RMTAC intervention
is likely to be cost-effective 99% and 57% of the time (for QALY and hospitalization
outcome, respectively). The analysis was robust to assumptions of follow-up visits
frequency and patients’ gender. Conclusions: Implementing RMTAC in Malaysia
has high probability of being more cost-effective than the usual care management
for both male and female subgroups across all age groups. Further investigation is
necessary to ensure that implementing this decision does not exceed the overall
national healthcare expenditure

Objectives: The aim of the study was to explore the association of waist circumference with glycaemic control in Malaysian patients with type 2 diabetes.
Methods: We utilised data of type 2 diabetes patients followed up in Malaysian public sector primary care clinics contained in the National Diabetes Registry in the year 2012. The variable of interest was poor glycaemic control, defined as HbA1c≥ 6.5%. Multiple logistic regression was used to explore the association between glycaemic control and waist circumference, which was adjusted for age, sex, duration of diabetes, systolic blood pressure, total cholesterol, use of insulin and other medications.
Results: A total of 98,825 patients with type 2 diabetes were included in the study. The mean age of patients was 59.9 years (SD: 10.9) and 38.9% were males. The mean duration of diabetes was 6.8 years (SD: 5.0) and 76.2% of patients had HbA1c ≥ 6.5%. The mean waist circumference was 94.0 cm (SD: 11.8) for male and 90.7 cm (SD: 11.8) for female; while 78.3% of the patients had waist circumference above the cut-off (≥ 90 cm for men and ≥ 80 cm for women). Larger waist circumference was found to be significantly associated with HbA1c≥ 6.5% (adj. OR 1.009; p< 0.001; 95% CI: 1.007–1.011) after adjusting for confounding factors.
Conclusions: Analysis showed that glycaemic control was poorer in patients with higher waist circumference than in patients with lower waist circumference.

Objectives: The aim of the study was to explore the association of waist circumference with microvascular complications in Malaysian patients with type 2 diabetes.
Methods: We utilised data of type 2 diabetes patients followed up in Malaysian public sector primary care clinics contained in the National Diabetes Registry in the year 2012. Variables of interest were the presence of microvascular complications, namely nephropathy and retinopathy. Multiple logistic regression was used to explore the association between presence of microvascular complications and waist circumference, which was adjusted for age, sex, duration of diabetes, systolic blood pressure, insulin use, total cholesterol and HbA1c.
Results: A total of 114,719 patients with type 2 diabetes were included in the study. The mean age of patients was 59.8 years (SD: 11.2) with mean duration of diabetes of 6.8 years (SD: 5.1). Male
patients comprised 39.9% of the sample population and 83.5% of the patients were overweight with BMI ≥ 23 kg/m2. Nephropathy and retinopathy was present in 9.1% and 7.9% of patients respectively. The mean waist circumference was 94.1 cm (SD: 11.8) for males and 90.8 cm (SD: 11.8) for females; while 78.4% of the patients had waist circumference above the cut off (≥ 90 cm for men and ≥ 80 cm for women). Larger waist circumference was found to be significantly associated with nephropathy (adj. OR 1.005; p-value< 0.001; 95% CI: 1.003–1.008) after adjusting for confounding factors. However, waist circumference was not significantly associated with retinopathy (adj. OR 0.998; p= 0.209; 95% CI: 0.996–1.001).
Conclusions: Analysis showed that patients with higher waist circumference were more likely to have nephropathy than patients with lower waist circumference. The analysis also showed that waist circumference was not associated with retinopathy in the study population.
