Background/aim: The HIV-infected population is aging, and the concomitant comorbidities increase the likelihood of polypharmacy. There is a scarcity of data for determining drug-related problems in people living with HIV/AIDS (PLWHA).
Materials and methods: This cross-sectional study was carried out between September 1, 2015, and July 1, 2016. All patients underwent a face-to-face interview with a clinical pharmacist. The 'PCNE Classification V 7.0.' was used classify incident drug-related problems (DRPs).
Results: The mean age of the patients was 40.4±13.06 years. The rate of polypharmacy was 66.1% in patients with comorbidities and 12.3% in those without comorbidities (p<0.001). DRPs were more prominent in older patients (46 vs. 37 years, p<0.001), with longer duration of antiretroviral therapy (ART) (45 vs. 27 months, p=0.014), and with lower education level (p=0.013). Receiving >3 ART drugs was associated with more DRPs in the logistic regression model (odds ratio: 8.299, 95% confidence interval: 1.924–35.803). Fifty-eight interventions were performed in 45 (24.9%) patients. Clinical pharmacist interventions were performed in 18.9% of patients without polypharmacy and in 38.9% of patients with polypharmacy (p<0.001).
Conclusion: DRPs and polypharmacy are common among elderly PLWHA. More interventions are warranted to boost the quality of life in aging PLWHA.
