The Role of an Infectious Diseases Faculty Pharmacist and Pharmacy Students on an Antimicrobial Stewardship Team at a Community Non-teaching Hospital.

Antimicrobial stewardship program implementation at non-teaching community hospitals differs due to staffing and resource disparities. Demonstrate that an infectious disease (ID) pharmacist faculty with advanced pharmacy practice experience (APPE) students can expand antimicrobial stewardship services at non-teaching community hospitals. A single-center, retrospective chart review was conducted comparing prospective audit and feedback antimicrobial stewardship interventions by an ID pharmacist faculty with and without APPE students between January 16, 2020 to January 16, 2021. The primary endpoints were intervention rate and the intervention acceptance rate. Secondary endpoints included: the difference in the time from antimicrobial order to intervention and length of stay, as well as comparison of acceptance rates stratified by intervention type or the antimicrobial intervened upon. A total of 739 antimicrobial stewardship interventions were made with an overall acceptance rate of 55.2%. The ID pharmacist faculty with APPE students had a higher number of interventions and intervention rate per working day compared to without students (428 vs 311 and 4.46 vs 2.99, respectively). Conversely, the intervention acceptance rate was lower for the ID pharmacist faculty with APPE students vs without (48.8% vs 64%, P < .001). Both the median time from antimicrobial order to the intervention and length of stay was lower for the ID pharmacist faculty with students vs without (2.50 days [interquartile range (IQR) 1.24 - 4.01] vs 2.99 days [IQR 1.64 - 4.95], P = .003, and 9.20 days [IQR 5.57 - 14.93] vs 11.69 days [IQR 6.89 - 22.31], P < .001, respectively). The acceptance rates by intervention type and the antimicrobial intervened upon were similar between groups. An ID pharmacist faculty with APPE students at a non-teaching community hospital increased the number of stewardship interventions, and was associated with decreased time from antimicrobial order to intervention and length of stay.
