Abstract

Aims of the study: This study aimed to investigate the prevalence and predictors of Drug-related problems (DRPs), as well as to evaluate the impact of DRPs on the health-related quality of life in geriatric patients with type 2 diabetes mellitus.

Methodology: A cross-sectional study was conducted over a three-month period. Patients aged 60 years and older visited diabetes clinics from October 1, 2022, to December 31, 2022, were included in the study. Data were collected through structured questionnaires, whereas lab results, medication records, comorbidities, and the consequences of DRPs were collected from electronic medical records. DRPs were identified and classified using the PCNE V501 classification system. Health-related quality of life (HRQoL) was evaluated using the validated EuroQol criteria.

Results: A total of 491 patients participated in the study, and the mean age of the patients was 67.51 years (SD = 5.84 years). Female patients represented 52.34% of total subjects. A total of 461 (around 94%) experienced at least one drug-related problem (DRP), ranging from one to nine DRPs per patient, with a total number of DRPs equal to 1625 identified. The most common DRP was the drug choice problem, affecting 52.98% of patients. Factors such as high drug frequency, living conditions, the number of diabetes medications, comorbidities, and smoking were significantly associated with higher numbers of DRPs. Higher numbers of DRPs were found to significantly worsen health-related quality of life (HRQoL) among patients.

Conclusion: Geriatric individuals with type 2 diabetes mellitus encounter a significant prevalence of DRPs, with drug choice problems being the most common followed by dosing problems. Risk factors contributing to these DRPs include high drug frequency, living conditions, high number of diabetes medications, multimorbidity, and smoking. Also, the study concluded that the increased number of DRPs was associated with negative impact on HRQoL domains in geriatric patients with type 2 diabetes.
