All blood culture contamination is local

Matthew Aaron Pettengill

Short summary

Blood culture collector dissatisfaction and avoidance of optional specimen diversion devices (ISDDs) limit their impact on reducing contamination, suggesting local factors are key.

Key points

  • Blood culture contamination (BCC) remains a significant clinical and financial issue.
  • Initial specimen diversion devices (ISDDs) show promise in reducing BCC.
  • Collector dissatisfaction and optional avoidance of ISDDs limit their effectiveness.
  • Local factors, not just the devices, are critical in controlling BCC.

Abstract

Blood culture contamination (BCC) has historically been a major issue with clinical and financial implications. Recent studies have shown that initial specimen diversion devices (ISDDs) can help reduce BCC, but a recent large study by C. Vieni, M. Legried, J. Mainella, K. Bute, et al. (J Clin Microbiol 64:e00085-26, 2026, https://doi.org/10.1128/jcm.00085-26) demonstrates that a major concern with ISDD implementation is blood culture collector dissatisfaction with the utilization of ISDDs and subsequent avoidance when use is optional. A variety of local factors may limit the potential impact of ISDDs.
