Abstract

The expanding scope of practice of hospital pharmacists has contributed to improvements in patient care; however, workload remains a barrier to the provision of optimal pharmaceutical care. Established ratios to guide clinical pharmacy staffing on medical and surgical units are lacking in Canada. To determine the pharmacist-to-patient ratio that allows for provision of comprehensive pharmaceutical care to each patient on a medical or surgical unit and to determine which comprehensive care tasks can be delivered in settings where staffing is limited. A multiphase study was conducted in 6 hospitals. First, a modified Delphi study was conducted to define and prioritize the elements of comprehensive pharmaceutical care. Next, a work sampling study was conducted to establish the frequency of each task and the time required for completion. Finally, a workforce calculator was used to determine pharmacy staffing ratios. Ten pharmacists participated in the modified Delphi study, and 31 participated in the work sampling study. A total of 15 comprehensive care tasks were identified, 7 of which were categorized as tasks to prioritize in settings where staffing is limited. The optimal staffing ratios were 1 pharmacist to 13 patients in internal medicine teaching units, 1 pharmacist to 26 patients in hospitalist or internal medicine nonteaching units, and 1 pharmacist to 14 patients in surgical units. The optimal staffing ratios determined in this study should enable pharmacists to provide comprehensive care to each patient. Implementing these staffing ratios could increase the consistency of clinical pharmacy services, improve patient outcomes, and improve pharmacists' work satisfaction. Further research is required to validate these ratios in a variety of settings.
