Hypothesis

What are the risk factors for Alcaligenes xylosoxidans bloodstream infections in outpatient oncology patients?

Conclusion

The study found that breaches in infection control led to a cluster of bloodstream infections caused by Alcaligenes xylosoxidans in patients with central venous catheters.

Supporting Evidence

  • 12 patients with A. xylosoxidans bloodstream infection were identified.
  • Case-patients were significantly more likely to have had a central venous catheter than controls.
  • The outbreak was linked to breaches in infection control practices.

Takeaway

Some patients got sick from a germ called Alcaligenes xylosoxidans because the doctors didn't follow the right rules to keep things clean.

Methodology

The study used a matched case-control study and a prospective cohort study to investigate the outbreak.

Potential Biases

The investigation was limited by the lack of medical records indicating when nursing staff accessed the CVCs.

Limitations

The original multidose vials used at the start of the outbreak were discarded and not available for testing.

Participant Demographics

All 12 case-patients were immunocompromised, aged 41 to 79 years, with a mean age of 65.8 years, and 83.3% were female.
