Health care-associated infection (HCAI) is the most frequent adverse event for hospitalized patients. Hand hygiene is a simple and effective solution to protect patients from HCAI. This study aimed to introduce hand hygiene to health care workers based on the World Health Organization guideline for reducing HCAI in Cambodia and to assess their behavioral patterns on hand hygiene. All health care workers at Kampong Cham provincial hospital had lectures and practice on hand hygiene in January 2012. The surveys for hand hygiene compliance (HHC) were performed after 6 months, 1 year and 2 years, respectively. The number of surgical site infections (SSI) was counted in 2011 and 2014. Our analysis used the data of 58 workers, who were observed at all three points, although 139 workers were observed during the study period. The average of HHC at 6 months, 1 year and 2 years were 62.37%, 85.76% and 80.36%, respectively. The improved group (HHC 2 years/1 year≧1) had 32 workers, whereas the worsened group (HHC 2 years/1 year<1) had 26. There was a significant difference in departments of the two groups (P=0.011) but not in sex, age or occupations. The improved group had more workers of General (31.2% vs. 19.2%), Surgical (25.0% vs. 11.5%) and Infection (21.9% vs. 11.5%) categories compared to the worsened group. The incidence of SSI was improved from 32.26% in 2011 to 0.97% in 2014. Our results suggest that the education and the survey on hand hygiene are effective for reducing HCAI in Cambodia.
