The short-term and long-term effectiveness of a multidisciplinary hand hygiene improvement program

BACKGROUND: Although hand hygiene (HH) compliance has been an important issue for years, the compliance rate is still a problem in health care today. METHODS: This was an observational, prospective, before-and-after study. We measured HH knowledge and HH compliance before (baseline), directly after (poststrategy), and 6 months after the performance of HH team strategies (follow-up). The study was composed of employed nurses and physicians working in the department of internal medicine of a university hospital. We performed a multifaceted improvement program including HH education, feedback, reminders, social influence activities including the use of role models, and improvement of HH facilities. RESULTS: Ninety-two nurses and physicians were included. Compared with baseline, there was a significant improvement in the overall mean HH knowledge score at poststrategy (from 7.4 to 8.4) and follow-up (from 7.4 to 8.3). The overall HH compliance was 27% at baseline, 83% at poststrategy, and 75% at follow-up. At baseline, the compliance rate was 17% in nurses and 43% in physicians and significantly improved to 63% in nurses and 91% in physicians at follow-up. CONCLUSION: Our multifaceted HH improvement program resulted in a sustained improvement of HH knowledge and compliance in nurses as well as physicians.status: publishe
