Abstract

Introduction: Surgical hand antisepsis (SHA) is a critical measure in preventing surgical site infections (SSIs). However, maintaining consistent compliance remains challenging without effective monitoring strategies. This study aimed to evaluate the effectiveness of using surface hand microbiological culture as a tool for monitoring SHA compliance and its impact on the SSI rates. Methods: A cross-sectional descriptive study was conducted. Surface samples from surgical team members' hands were collected after SHA and cultured for microbial detection. Compliance behavior was monitored via camera surveillance. SSI rates were tracked before and after the intervention. Statistical significance was determined as p < 0.05. Results: The positive culture rate after SHA was 4.3%. Following the intervention, SHA compliance increased from approximately 60% to around 90%. Meanwhile, the SSI rate decreased from 0.25% (pre-intervention) to 0% (post-intervention), with a statistically significant difference (p = 0.031). Conclusion: Microbiological culture of hand surfaces is an effective monitoring method that enhances awareness, improves compliance with SHA protocols, and significantly reduces surgical site infections.
