Key Points Question Are blood cultures collected and processed in Israel in accordance with best practice standards? Findings In this quality improvement study that included 28 hospitals (348 987 blood culture bottles), an estimated 24% of adult bloodstream infections went undetected because of undersampling of patients, use of solitary blood cultures, or lack of anaerobic bottles. Median time from blood draw to pathogen identification was 34 hours longer than best practice. Meaning The findings of this study suggest that interventions to improve blood culturing processes are needed.
