RESUMO
PURPOSE: To compare the number of antiretroviral-related clinically significant drug-drug interactions (CSDDIs) occurring in hospitalized patients that were intervened upon before and after Antiretroviral Stewardship Program (ARVSP) expansion and to classify the interventions made to prevent errors. METHODS: A retrospective chart review of adult patients treated with antiretroviral therapy (ART) and who were hospitalized from September 2012 to February 2013. A CSDDI was defined as requiring an alternative therapy, dose adjustment, or schedule modification. Findings were compared to a prior study. RESULTS: A total of 185 admissions were included and 76 CSDDIs were identified, 19 (25%) occurred after ART approval. The percentages of CSDDIs that occurred after ART approval and were intervened upon before and after ARVSP expansion were 43% and 95%, respectively (P<.001). An additional 80 other interventions were made by the ARVSP. CONCLUSION: An ARVSP is critical in the prevention of CSDDIs and errors to improve safety in HIV-infected patients.
