Medication Adherence among Patients with Non-Communicable Diseases in a Tertiary Hospital: A Descriptive Cross-sectional Study

Abstract

Introduction: Non-communicable diseases (NCDs) are a leading cause of mortality, with a projected rise from 38 million in 2012 to 52 million by 2030. Among NCDs, hypertension, diabetes and Chronic Obstructive Pulmonary Disease are the major burdens in healthcare today, requiring long-term therapies and a significant effort in maintaining treatment adherence. Methods: A descriptive cross-sectional study design was adopted to determine medication adherence among patients with non-communicable diseases using non-probability, consecutive sampling techniques after ethical approval from same institute (Reference number: 524). Medication adherence was assessed on 322 patients attending the outpatient department, using a structured interview schedule, after getting Ethical approval from the Institution Review Committee. Morisky medication adherence scale (MMAS-4), Culig adherence Scale, and Beliefs about Medications (BMQ) tool were used to determine the adherence level, causes of non-adherence and belief in medication respectively. Data was coded and analysed using SPSS version 16. Descriptive statistics were used to summarise the data. Results: The study population exhibited a mean age of 58 ± 12.80 years, with male participants 190 (59.01%). The present study revealed that 148 (45.96%) of the participants have a high adherence level to prescribed medication, and 246 (76.40%) strongly believed that without medication they would be very sick and life would be impossible. Conclusions: The study found that less than half of participants fully adhered to prescribed medicine, with forgetfulness identified as a primary cause of non-compliance.
