BackgroundThe surrounding environment influences the constitution of illness perceptions. Therefore, local research is needed to examine how Libyan diabetes patients perceive diabetes and how their perceptions influence their medication adherence.MethodsA cross-sectional study was conducted at the National Centre for Diabetes and Endocrinology in Tripoli, Libya, between October and December 2013. A total of 523 patients with type 2 diabetes participated in this study. A self-administered questionnaire was used for data collection; this included the Revised Illness Perception Questionnaire and the eight-item Morisky Medication Adherence Scale.ResultsThe respondents showed moderately high personal control and treatment control perceptions and a moderate consequences perception. They reported a high perception of diabetes timeline as chronic and a moderate perception of the diabetes course as unstable. The most commonly perceived cause of diabetes was Allah's will. The prevalence of low medication adherence was 36.1%. The identified significant predictors of low medication adherence were the low treatment control perception (p=0.044), high diabetes identity perception (p=0.008), being male (p=0.026), and employed (p=0.008).ConclusionDiabetes illness perceptions of type 2 diabetic Libyans play a role in guiding the medication adherence and could be considered in the development of medication adherence promotion plans.

Background: Despite the apparent benefits of disease-modifying drug (DMD) use among multiple sclerosis (MS) patients, their rates of adherence are often variable and in some cases are quite low. Aim of the study: To assess medication adherence and its relationship with treatment satisfaction of MS patients in Saudi Arabia Patients and methods: Following a cross-sectional design, 598 adult MS patients were recruited from all tertiary care hospitals in all regions of Saudi Arabia. Patients' medication adherence was assessed using the Arabic version of the eight-item Morisky Medication Adherence Scale (MMAS-8). Treatment satisfaction was assessed using the Treatment Satisfaction Questionnaire for Medication. Disease severity was assessed using the Patient-Determined Disease Steps (PDDS). Results: The most used drug was interferon beta-1b (24.1%), while 18.7% were using interferon beta-1a and 17.4% were using fingolimod. Patients' mean PDDS was 2.8 ± 1.9. Only 9.7% were "adherent" to medication. Patients' adherence differed according to their educational level (p < 0.001), their currently received medications (p = 0.032), with those on Fingolimod having the highest adherence (17.3%). Treatment satisfaction was significantly higher among adherent patients (p < 0.023). The main reasons for changing prescribed drugs were the presence of attacks, i.e., response to treatment was substandard (41.8%) and the experienced side effects of used drugs (39.9%). PDDS differed significantly according to patients' treatment adherence only among those receiving interferon beta-1b, with higher mean severity score among those who were adherent (p = 0.002). Conclusions: Medication adherence among MS patients in Saudi Arabia is low. Higher adherence is associated with patients' higher education. The main underlying reasons for changing prescribed drugs are the presence of attacks, substandard response to treatment, or suffering the DMDs' side effects. Medication adherence is associated with higher treatment satisfaction.

“…Total scores obtained from MMAS-8 range from 0 to 8, with scores of <6, 6 to <8, and 8 indicating low, medium and high adherence, respectively. Patients with total MMAS-8 scores <6 were considered non-adherent, while MMAS-8 scores ≥ 6 were considered adherent [11,12].…”

Background: Diabetes mellitus is a serious health problem. It is considered the third leading cause of deaths among chronic diseases in the Gaza Strip, Palestine. Among diabetic patients, T2DM constitute the majority (92.2%). Medication adherence is a key determinant of therapeutic success. No studies have previously investigated medication adherence among T2DM patients in Gaza. Objectives: To assess medication adherence and its association with glycemic control among T2DM patients. Setting: Al-Rimal Martyr's clinic in Gaza, Palestine. Methods: A cross-sectional study with a convenience sample of 148 T2DM patients. The study used MMAS-8, last value of the HbA1c test, MDKT and BMQ to assess medication adherence, glycemic control, DM-related knowledge and beliefs about medicines, respectively. Main outcome measures: Level of medication adherence and rate of glycemic control. Results: The mean age of the patients was 59.4 ± 8.6 years. More than half of the patients (52%) were females. The mean adherence score was 5.5 ± 1.4. Approximately 52.7% of patients were non-adherent. 83 patients (56.1%) were poor glycemic controlled. Poor glycemic control was significantly associated with non-adherence. 95 patients (64.2%) had a low level of knowledge about DM. The mean scores of BMQ scales were 17.8 ± 3.62, 12.4 ± 3.63, 12.5 ± 3.50, 12.3 ± 2.79 for specific-necessity scale, specific-concerns scale, general-harm scale, general-overuse scale, respectively. Medication non-adherence was significantly associated with unmarried status, diet noncompliance status, and education about DM and patients' negative beliefs about medicines as a whole. Conclusion: Most patients were medication non-adherents and poor glycemic controlled. Improving patients' medication adherence may improve glycemic control.
