Insights

Neurosurgical antimicrobial prophylaxis in China shows significant practice gaps, with prolonged durations and missed re-dosing. Adhering to guidelines could halve antimicrobial use and costs, highlighting the need for stewardship.

Area of Science:

  • Medical Microbiology
  • Surgical Prophylaxis
  • Health Economics

Background:

  • Antimicrobial prophylaxis audits identify prescribing gaps in healthcare.
  • Limited data exists on neurosurgical perioperative antimicrobial prophylaxis costs, quality, and use in China.

Purpose of the Study:

  • To assess the appropriateness of perioperative antimicrobial prophylaxis in neurosurgery.
  • To analyze the associated costs, quality, and antimicrobial use density.

Main Methods:

  • Retrospective study of 262 neurosurgical patients without infections in 2017.
  • Evaluation of prophylaxis appropriateness against international and Chinese guidelines.
  • Analysis of discrepancies in indication, choice, dose, route, timing, re-dosing, and duration.

Main Results:

  • 82.8% of procedures had inappropriately prolonged prophylaxis duration.
  • 32.1% of procedures missed intraoperative re-dosing.
  • Antimicrobial choice (95%) and timing (100%) were generally appropriate.
  • Guideline adherence could reduce defined daily doses by 46.9% and costs by 75.5% ($2000 to $490).

Conclusions:

  • Significant discrepancies exist in current neurosurgical perioperative antimicrobial prophylaxis practices.
  • Improved antimicrobial stewardship is crucial for optimizing prophylaxis in China.
  • Implementing guidelines can lead to substantial reductions in antimicrobial use and healthcare costs.
