Background: Following the rapid aging of population, some concerns have emerged regarding increasing demand for health care services and the consequent increase in health costs. Besides, older adult patients with chronic disease are more prone to show cost-related medication non-adherence (CRN) to cope with their medication costs. The objective of this qualitative study was to develop an adopted conceptual framework on the contextual determinants that affect the CRN in older adult patients with chronic diseases.
Methods: Problem-centered, semi-structured, in-depth, and face-to-face interviews, were conducted with healthcare informants in Iran, from Sep. 2021 to Feb. 2022. Collected data were analyzed using deductive and inductive analytic approaches and content analysis methodology was used to develop the model. This study applies to the COREQ checklist.
Results: Fifteen informants, including 8 (60%) males, with mean ± SD age of 44.4 ± 9.7 years, entered into the study. Based on the data analysis performed on the information obtained from the interview with 3 subgroups of geriatricians, health policymakers, and pharmacists, six major themes identified as determinants: 1) socio-economic factors, 2) health system-related factors, 3) healthcare provider-related factors, 4) medication-related factors, 5) disease-related factors, and 6) patient-related factors. There were also 23 minor themes which were matched with the aforementioned six major themes.
Conclusion: The final framework obtained in this qualitative study depicts CRN as an issue that is highly likely affected by six main determinants among older patients with chronic disease. Our findings emphasize that policymakers would focus on certain major themes and allocate resources to programs to improve medication therapy management in older adult patients.
