BACKGROUND: In 2024, a global shortage of BD BACTEC blood culture bottles disrupted clinical practices worldwide. This study assessed the impact of the shortage on blood culture performance metrics and evaluated the effectiveness of management strategies implemented at a Japanese university-affiliated hospital. METHODS: This single-center, retrospective observational study was conducted between June 29, 2024, and September 25, 2024, and analyzed two phases: the pre-shortage period and the shortage period. During the shortage, clinicians were instructed to collect only one blood culture set per patient, with exceptions allowed for specific conditions. Interrupted time-series analysis was performed to examine changes in blood culture performance indicators. RESULTS: A total of 4490 blood cultures were collected during the study period. The proportion of cases with two or more sets collected and the contamination rate of blood cultures significantly decreased during the shortage period. Additionally, the positivity rate of blood cultures also significantly declined compared to the pre-shortage period. Candida species were isolated more frequently during the shortage period, while no significant changes were observed for other organisms. CONCLUSIONS: The adoption of simplified instructions enabled a rapid transition to single-set blood culture collection during the supply shortage. However, this approach reduced the blood culture positivity rate and hindered contamination rate assessment. These findings highlight the critical need for a stable supply of blood culture bottles and the importance of continued education on optimal blood culture collection practices.
