Background: Two affiliated teaching hospitals in Chicago, Illinois, participated in an ethnographic study of hospital-based inpatient antimicrobial stewardship programs and interventions between 2017 and 2018. Although antimicrobial stewardship is now a requirement in medical practice, it is not clear how infectious disease physicians perceive and understand antimicrobial stewardship. Over a period of 18 months, we directly observed infectious disease practice to better understand how antimicrobial stewardship is conducted among physicians within the same specialty. Methods: A doctoral candidate medical anthropologist conducted semistructured interviews with infectious disease attending physicians and fellow physicians (N = 18) at 2 affiliated teaching hospitals in Chicago, IL, between July 2017 and March 2018 as part of an ethnographic study involving direct observation of inpatient care. Interview questions focused on 3 key domains: (1) descriptions of antimicrobial use among hospital-based physicians, (2) solicited definitions of antimicrobial stewardship, and (3) experiences practicing as an infectious disease consultant. Physicians who were directly involved with the antimicrobial stewardship program were excluded from this analysis. Transcriptions of the data were analyzed using thematic coding aided by MAXQDA qualitative analysis software. Results: Infectious disease physicians have a robust understanding of antimicrobial stewardship (Table 1). Infectious disease physicians described other hospital-based physicians as regularly overusing and misusing antimicrobials, compared with their practice, which they described as “thoughtful.” Definitions in response to the question “What is antimicrobial stewardship?” centered on guiding the prescribing behavior of others. Infectious disease physicians valued stewardship and were concerned with lack of adherence to antimicrobial prescribing recommendations among other hospital-based physicians, behaviors which infectious disease physicians viewed as perpetuating antibiotic resistance. Finally, infectious disease physicians found serving as antimicrobial stewards during their everyday practice to be challenging based on their role as consultants to the primary service. Conclusions: Our qualitative analysis revealed that infectious disease physicians not regularly involved in antimicrobial stewardship are highly motivated stewards who perceive their hospital-based colleagues to be less effective at appropriately prescribing antimicrobials. As consultants, infectious disease physicians are not autonomous decision makers. However, as antimicrobial stewardship programs search for champions, infectious disease physicians could be better utilized as knowledgeable and motivated individuals who can make the case for stewardship.Funding: NoneDisclosures: None
