DisclaimerIn an effort to expedite the publication of articles related to the COVID-19 pandemic, AJHP is posting these manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.PurposeA prospective observational study was conducted to assess sterile compounding time and workforce requirements in a hospital pharmacy, resulting in development of staff benchmarking metrics.MethodsThe study was conducted in the IV room of a quaternary hospital over a total of 7 weeks. Compounding was directly observed and timing data collected for each compounded sterile preparation (CSP). The primary objective was to assess CSP workload, compounding time requirements, and workforce requirements to enable development of a data-driven staffing benchmark.ResultsA total of 320 sterile product preparations were directly observed during the study. Overall, the average time to compound 1 CSP (including small- and large-volume parenteral solutions, chemotherapy CSPs, batched CSPs, and syringes) was 3.25 minutes. Chemotherapy CSPs had the longest average preparation time (17.74 minutes); batched CSPs had the shortest preparation time, at 1.90 minutes per unit. A safe workload analysis indicated that in an 8-hour shift, 1 pharmacy technician can safely prepare 253 batched CSPs; 148 preparations of SVP solutions, LVP solutions, and syringes combined; 31 parenteral nutrition solutions prepared using an automated device; or 29 chemotherapy preparations. Through extrapolation of these results, it was calculated that a hospital with a capacity of 100 beds would require 1.4 pharmacist full-time equivalents (FTEs) and 2.7 technician FTEs to meet its sterile compounding needs, with proportionate increases in those estimates for a 300-bed hospital.ConclusionOrganizations wishing to use external benchmarking information need to understand data characterization, pharmacy services offered, automation, workflows, and workload before utilizing that information for workforce planning.
