Polypharmacy and Medication Compliance among Patients with Type 2 Diabetes in Oman: A Cross-Sectional Study

The goal of this study was to estimate the prevalence of polypharmacy and medication compliance among patients with T2DM at a primary care clinic in Muscat, Oman, to determine whether various sociodemographic and clinical factors were associated with polypharmacy and to assess relationships between polypharmacy, compliance, and self-related health. It is a cross-sectional study conducted between September and November 2019 and included all adult T2DM patients attending the clinic. Data were collected using a questionnaire, face-to-face interviews, and electronic medical records. A total of 202 T2DM patients were included. The majority were female (56.9%) and ≥60 years old (45.5%). Most had two or more chronic health conditions (66.3%). The prevalence of polypharmacy was 83.1%. Overall, 65% and 92% of patients reported a high level of adherence to treatment and good-to-excellent health, respectively. In conclusion, Polypharmacy was common among T2DM patients and was significantly associated with age, common comorbidities, and T2DM duration.
