AimTo investigate the cost-avoidance associated with implementation of an overnight emergency medicine pharmacist (EMP) through documented clinical interventions.DesignRetrospective evaluation of prospectively tracked interventions in a single Level I Trauma, Comprehensive Stroke Center, from November 25, 2020 through March 12, 2021 during expanded emergency medicine service hours (2300-0700).InterventionsOne of 45 clinical patient-care recommendations associated with cost-avoidance were available to be selected and documented by the EMP; more than one intervention was allowed per patient, though one clinical intervention could not be counted as multiple items. Documented services were associated with monetary cost avoidance based upon available literature assessing pharmacy clinical interventions. Differences in time from imaging to systemic thrombolytics and percentage of patients meeting door-to-alteplase benchmarks were compared with and without the availability of EMPs.ResultsOvernight EMPs documented 820 interventions during 107 overnight shifts with a cost avoidance of $612,974. The most common interventions were bedside monitoring (n = 127; $50,694), drug information consultation (97; $11,269), and antimicrobial therapy initiation and streamlining (95; $60,101). When categorizing interventions, 378 (46%; $292,484) were input as hands-on care, 216 (26%; $94,899) as individualization of patient care, 135 (17%; $25,897) as administrative and supportive tasks, 84 (10%; $121,746) as adverse drug event prevention, and 7 (1%; $77,964) as resource utilization. All patients (n = 6) with an acute ischemic stroke during the evaluation period received systemic thrombolytics ≤45 min in the presence of EMPs compared with 50% receiving thrombolytics ≤45 min without EMPs.ConclusionsExpanded overnight coverage by EMPs provided clinical bedside pharmacotherapy expertise to critically ill patients otherwise not available prior to study implementation. Clinical interventions were associated with substantial cost-avoidance.Copyright © 2024. Published by Elsevier Inc.
