title: Blood culture collection through peripheral intravenous catheters increases the risk of specimen contamination among adult emergency department patients.
abstract: Five hundred five blood cultures collected through a peripheral intravenous catheter (PIV) in an emergency department were matched to cultures obtained by dedicated venipuncture from the same patient within 10 minutes. The relative risk of contamination for cultures collected through PIVs compared with dedicated venipuncture was 1.83 (95% confidence interval, 1.08-3.11).
