Factors Influencing Medication Non-Adherence in Patients with Chronic Diseases and Disabilities: Insights from a National Survey in Indonesia.

PURPOSE

Medication non-adherence remains a problem in the long-term management of chronic disease among patients with disabilities. This study aimed to assess the prevalence of medication non-adherence among patients with chronic diseases and disabilities in Indonesia and to identify the factors associated with medication non-adherence among these patients.

PATIENTS AND METHODS

This cross-sectional analysis was conducted using national data from the 2014 Indonesian Family Survey (IFLS-5). A self-report questionnaire was used to collect information on all chronic diseases, disability, medication non-adherence, and sociodemographic characteristics. Logistic regression analysis was carried out to identify factors contributing to medication non-adherence. Odds ratios (ORs) with 95% confidence intervals (CIs) were presented.

RESULTS

The study included 1908 patients with chronic diseases and disabilities, with 66.3% identified as non-adherent to medication. Factors associated with medication non-adherence included being aged 15 to 30 years (OR = 1.65; 95% CI = 1.19-2.30) and 31 to 45 years (OR = 1.36; 95% CI = 1.01-1.84), self-perceived health status as somewhat healthy (OR = 1.36; 95% CI = 1.09-1.69) or very unhealthy (OR = 1.73; 95% CI = 1.08-2.77), had no active days missed due to poor health (OR = 1.51; 95% CI = 1.09-2.10), and non-use of any hearing, visual, or walking aids (OR = 1.24; 95% CI = 1.01-1.52).

CONCLUSION

More than half of the patients (66.3%) with chronic diseases and disabilities were non-adherent to their medication. Therefore, interventions designed to improve medication adherence in this population should consider specific patient-related factors.
