Impact of stewardship interventions on antiretroviral medication errors in an urban medical center: a three year, multi-phase study.

At baseline, nearly half of patients prescribed antiretroviral treatment for HIV at a university hospital had at least one medication error and 38% had uncorrected errors at discharge. Introducing education and computerized provider order entry only slightly decreased those rates. Launching a stewardship program with prospective audits and feedback in the third year of the study reduced errors at discharge to 12%.
