This cross-sectional study was conducted to evaluate the prevalence of polypharmacy among PLWH who were on antiretroviral treatment and were followed in an outpatient setting by the pharmacy department of several hospitals across Spain. In addition, we aimed to evaluate factors associated with polypharmacy and treatment complexity among this population. Material and methodsWe recorded information on demographic data, data on disease control including viral load and CD4 count at the time of inclusion, comorbidities, pharmacologic treatment and drugs interactions. Polypharmacy was defined as the use of 6 or more different drugs, including antiretroviral medication; major polypharmacy was defined as the use of ≥11 different drugs. ResultsOverall, 1225 PLWH were eligible in the study. The median (IQR) age was 49 (40–54). Comorbidities were present in 819 (67%) PLWH and 571 (47%) had two or more comorbidities. Overall, 397 (32.4%, 95% CI 29.8–34.9) PLWH met the criteria for polypharmacy, and 67 (5.5%, 95% CI, 4.2–6.7) had major polypharmacy. Several factors were associated with polypharmacy such as type of antiretroviral treatment, presence of potential interactions, the use of several types of medications and the number of comorbidities. Treatment complexity was also a factor strongly associated with polypharmacy; for each point increase in the medication regimen complexity index (MRCI), the likelihood of polypharmacy increased 2.3-fold. ConclusionsPolypharmacy is frequent among PLWH in Spain and contributes to a relevant extent to treatment complexity. ER -
