A national survey of the infectious diseases and antimicrobial stewardship pharmacist workforce in the United States: work settings, characteristics, employment activities, resources and needs.

Purpose: This national survey aimed to describe the work settings, characteristics, employment activities, scope, functions, and challenges of the pharmacist workforce responsible for infectious diseases (ID) and antimicrobial stewardship (AMS)-related tasks in the U.S. Methods: An internet-based Results: A total of 796 pharmacists with ID or AMS job responsibilities responded (3.5% response rate), with 607 working clinically or administratively in ID or AMS further categorized in four mutually exclusive groups based on formal and informal ID/AMS responsibilities. Respondents were predominantly female (66%), less than 40 years of age (59%) and white (82%). ID-specific training was completed by 41.8%, and 74% reported having student loan debt at graduation. Work-related activities were diverse and most frequently included: staffing or taking calls on weekends related to ID/AMS, AMS, educating learners or healthcare providers about ID-related topics, precepting learners, and conducting ID-related research and/or quality improvement projects. Respondents frequently indicated they lacked adequate job resources. Conclusions: The results highlight the extensive responsibilities placed on ID/AMS pharmacists to fulfill multiple roles. Pharmacists frequently lack ID-specific training or dedicated time for AMS responsibilities. The workforce is young, suggesting a need for both increased capacity for training programs and strategies for workforce retention.
