BackgroundComplexity of antiretroviral therapy (ART) for human immunodeficiency virus (HIV) and lack of experience with treatment regimens by providers may lead to medication-related errors (MRE). Consequences of MRE may include loss of virologic suppression, development of ART resistance, HIV transmission, and increased morbidity and mortality. The purpose of this study was to compare ART-related MRE and linkage to care through consultation with Infectious Diseases (ID) providers as a result of ID-pharmacist review.MethodsAn ID pharmacist-led intervention incorporating prospective review of electronic medical records of adult patients admitted with an ICD-10 code for HIV was implemented. Patients not on ART were triaged for linkage to care with ID consultation, and those on ART received profile review to assess for and correct MRE. We then conducted an IRB-approved, quasi-experimental cohort study comparing adult patients living with HIV who were admitted between February 2017 to June 2017 (pre-intervention) and October 2018 to March 2019 (post-intervention). Patients on ART for indications other than the treatment of HIV were excluded. Rates of ART-related MRE and frequency of ID consultation with linkage to care were compared before and after our intervention.ResultsA total of 200 patients were included, with 100 patients in each of the intervention periods. The institutional stewardship program intervened to correct one error in the pre-intervention period, whereas 119 interventions were made in the post-intervention period with an acceptance rate of 97%. The proportion of patients who experienced an MRE decreased from 70% to 25% (absolute risk reduction 45%, P < 0.01). The total number of errors also decreased between intervention periods (102 vs. 36, P < 0.01). A description of ID pharmacist intervention type is provided in Figure 1. To link patients into care or clarify an ART regimen, the number of ID consults significantly increased from 19% to 39% (P < 0.01) as a result of the ID pharmacist-led initiative.ConclusionFocused ID pharmacy review of patients admitted with HIV and inpatient ART prescription as part of an antimicrobial stewardship program was successful in reducing ART-related MRE and increasing ID consultation to promote linkage to care.
