Pharmacist-led antimicrobial stewardship program in an urgent care setting.

Purpose: While many programs have demonstrated pharmacist-led antimicrobial stewardship successes in inpatient and emergency department (ED) settings, there is a paucity of literature exploring these initiatives in urgent care (UC) sites. This study aimed to determine the impact of implementing a pharmacist-led antimicrobial stewardship program (ASP) in the UC setting.

Methods: A retrospective quasi-experimental study was conducted evaluating UC patients with positive urine or wound cultures following discharge. A collaborative practice agreement was implemented in 2015 allowing for pharmacist-led UC culture follow-up via a stewardship-focused protocol. The primary outcome of this study was to compare guideline-concordant antibiotic prescribing between the pre-ASP and post-ASP groups. Secondary outcomes included comparing the number of patients who required follow-up, time to follow-up, UC or ED revisits within 72 hours, and hospital admission within 30 days between groups.

Results: A total of 300 patients were included in the study (pre-ASP, n = 150; post-ASP, n = 150). Total guideline-concordant prescribing for all diagnoses was significantly improved in the post-ASP group (pre-ASP, 41.3% versus post-ASP 53.3%, p = 0.037). Additionally, guideline-concordant antibiotic selection improved in the post-ASP group (pre-ASP, 51% versus post-ASP, 68%, p = 0.01). Follow-up was required for 27 (18%) patients in the pre-ASP group compared with 16 (10.7%) in the post-ASP group (p = 0.07). Median time to follow-up call was longer in the post-ASP group (38 versus 71 hours, p < 0.001). There were no differences in UC and ED revisits within 72 hours (p = 1.0) or hospital admissions within 30 days (p = 0.723).

Conclusion: A pharmacist-led urgent care ASP was associated with significantly improved guideline-concordant antimicrobial prescribing.
