Digging Deep: Medication Adherence in Chronic Diseases and Its Association With Patient Satisfaction and Stress in an...

Introduction Medication adherence is a critical aspect of managing chronic diseases. Poor medication adherence leads to therapeutic failures and increased health costs, and puts patients at potentially life-threatening risks.The impact is felt drastically by patients suffering from chronic diseases. Patient satisfaction is known to be strongly associated with medication adherence. Psychosocial factors such as depression have been proven to negatively affect medication adherence; however, to our best knowledge, the association of stress with adherence remains largely unexplored. Objectives The aim of this study is to explore or assess the relationship between medication adherence, patient satisfaction, and stress levels. Methods A cross-sectional observational study was conducted within an Indian metropolitan city (Mumbai) among adults diagnosed and treated for at least one chronic disease with a medication regimen spanning over three months. An online questionnaire was designed, incorporating validated scales such as the Adherence to Refills and Medications Scale, Short Assessment of Patient Satisfaction, and Perceived Stress Scale. Results In the study, 23.7% of participants (n=300) showed adherence to their prescribed treatment regimen. Adherence exhibited a positive association with age (p=0.009) and educational attainment (p=0.031). Additionally, a significant gender difference emerged, with males (28%) displaying higher adherence rates compared to females (16.7%) (p=0.036). Furthermore, participants reporting lower stress levels exhibited higher adherence (39.5%), while those experiencing moderate-to-high stress levels displayed reduced adherence rates (17-18.8%) (p<0.05). Patient satisfaction was also linked to adherence, as satisfied individuals demonstrated higher adherence levels (29.1%) in contrast to dissatisfied counterparts (15.7%) (p=0.011). Conclusion Level of medication adherence is much lower in India as compared to other developed nations. Various demographic factors such as age, sex, and education status influence adherence. Physician counselling plays an important role in adherence, and satisfied patients are far more adherent. Furthermore, a significant negative association was found between stress and adherence.
