1306. Evaluation and Predictors of Antiretroviral (ART)-Related Medication Errors in Hospitalized People Living with HIV (PWLH)

BACKGROUND: As HIV has become a chronic condition, management of the disease and preventing resistance is paramount to improving patient outcomes. Medication errors can lead to suboptimal therapy and potential development of resistance. The purpose of this study was to identify the rate of antiretroviral (ART)-related medication errors in hospitalized people living with HIV (PWLH). METHODS: This was a multi-center, retrospective cohort study of patients diagnosed with HIV and/or AIDS based on International Classification of Diseases codes. Patients were included if they were at least 18 years old and hospitalized between March 2016 and March 2018. Patients were excluded if they were pregnant and only received intravenous zidovudine during their hospitalization. Of the patients eligible for inclusion, 400 were randomly selected and included in this study. The primary objective was to determine the rate of inpatient ART-related medication errors. Secondary objectives included the type of errors and rate of error resolution prior to discharge. RESULTS: A total of 203 ART-related medication errors occurred during the study period (mean 0.9 ± 1.2 errors per patient). Incorrect schedule was the most common type of error followed by incorrect or incomplete regimen. More errors occurred in male patients (P = 0.01), those known to be infected with HIV on admission (P < 0.05), and in patients with an undetectable viral load (P = 0.01). Approximately 30% of ART-related medication errors were resolved prior to discharge, of which pharmacists were responsible for 25%. Incorrect schedule, incorrect or incomplete regimen, and clinically significant drug-drug interaction (DDI) were the most common medication errors that persisted at discharge. Among resolved errors, resolution of clinically significantly DDI or incorrect/incomplete ART were the most common interventions. CONCLUSION: ART-related medication errors continue to occur in hospitalized PLWH and frequently persist at discharge. Interventions should be developed to reduce rates of ART-related medication errors on admission. Antimicrobial stewardship programs serve as an ideal platform to incorporate ART stewardship into routine activities to help minimize errors while inpatient and during transitions of care.
