OBJECTIVE: To understand healthcare workers' (HCWs) beliefs and practices toward blood culture (BCx) use. DESIGN: Cross-sectional electronic survey and semi-structured interviews. SETTING: Academic hospitals in the United States. PARTICIPANTS: HCWs involved in BCx ordering and collection in adult intensive care units (ICU) and wards. METHODS: We administered an anonymous electronic survey to HCWs and conducted semi-structured interviews with unit staff and quality improvement (QI) leaders in these institutions to understand their perspectives regarding BCx stewardship between February and November 2023. RESULTS: Of 314 HCWs who responded to the survey, most (67.4%) were physicians and were involved in BCx ordering (82.3%). Most survey respondents reported that clinicians had a low threshold to culture patients for fever (84.4%) and agreed they could safely reduce the number of BCx obtained in their units (65%). However, only half of them believed BCx was overused. Although most made BCx decisions as a team (74.1%), a minority reported these team discussions occurred daily (42.4%). A third of respondents reported not usually collecting the correct volume per BCx bottle, half were unaware of the improved sensitivity of 2 BCx sets, and most were unsure of the nationally recommended BCx contamination threshold (87.5%). Knowledge regarding the utility of BCx for common infections was limited. CONCLUSIONS: HCWs' understanding of best collection practices and yield of BCx was limite...
