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.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
