Comparison of prior authorization and prospective audit with feedback for antimicrobial stewardship.

Objective: Although prior authorization and prospective audit with feedback are both effective antimicrobial stewardship program (ASP) strategies, the relative impact of these approaches remains unclear. We compared these core ASP strategies at an academic medical center.

Design: Quasi-experimental study.

A retrospective analysis of the effect of patient-specific factors on voriconazole concentrations in oncology patients.

Objective: To identify patient-specific factors significantly associated with voriconazole exposure. DESIGN SETTING, AND PARTICIPANTS: Retrospective, single center at an academic medical center. Consecutive, adult oncology inpatients who received voriconazole by mouth and had at least one voriconazole level over a 14-month period.
