BACKGROUND: We describe a multifaceted intervention deployed amidst a blood culture (BC) bottle shortage and its impact on BC yields.
METHODS: Cross-sectional study conducted at a large safety-net hospital. BC bottle conservation strategies focused on improving blood volume collection, discouraging orders for low-yield conditions, limiting BC orders to 1 set per patient and restricting repeat BC to greater than 48-hour intervals. Trends in BC positivity rates and bloodstream infection events were analyzed using control charts, with a 13-month baseline period, and 12-month intervention period.
RESULTS: A total of 35,449 BCs were analyzed. The overall median percent positivity increased from 8.6% to 12.6% (P = .001). In the Emergency Department, the median percent positivity rose from 12.4% to 14.3% (P = .03); in Intensive Care Units (ICU), from 6.8% to 11.6% (P = .001); and in Medical-Surgical units, from 4.9% to 9.0% (P = .001). No significant variability in the counts of positive BCs was observed. The median blood volume per set increased from 5.7 to 7.5 mL (P = .001). Vancomycin use and acute ICU transfers remained stable.
CONCLUSIONS: The implementation of BC bottle conservation measures did not negatively impact BC yields or patient safety indicators. Prospective studies are needed to re-evaluate traditional BC ordering and collection practices.
