Implementation of a pharmacist-led ARVSP in an academic hospital to reduce ART errors

The primary objective was to compare the percentage of Antiretroviral Therapy (ART) uncorrected errors during hospital admission before and after the implementation of an Antiretroviral Stewardship Program (ARVSP).

This was a 2-year single-center, pre-post quality improvement study. Included in the study were admitted patients at least 18 years of age, diagnosed with human immunodeficiency virus (HIV), and taking at least 1 antiretroviral. The baseline percentage of uncorrected ARV errors was retrospectively determined during the first year. The second year consisted of implementing an ARVSP that prospectively audited ART orders. The ARVSP consisted of a pharmacy resident, a medical resident, an infectious disease, HIV trained pharmacist, an infectious disease physician, and ancillary health care providers. The impact of the ARVSP was assessed by comparing the percentage of uncorrected errors between the 2 time periods.

The number of uncorrected errors were 64.1% versus 31.1% before and after ARVSP implementation, respectively (P < 0.05). Delay in therapy errors were statistically significantly reduced (30.1% vs. 22.2%; P < 0.05). The time to overall correction of any error before ARVSP was 3.1 days, and after ARVSP, it was 1.8 days (P = 0.11).

Implementation of an ARVSP reduces the number of uncorrected antiretroviral-related errors. Because health care resources are finite and focused on the acute care of hospitalized patients, this multidisciplinary practice model may provide a practical approach for similar institutions to improve antiretroviral stewardship surveillance in the inpatient setting.
