Hand hygiene is an effective strategy for the prevention of health care-associated infection (HAI). We investigated the effect of a hand hygiene promotion strategy introducing alcohol-based handrub (AHBR) on the incidence of HAI in a university hospital in Colombia.


A Prospective cohort study was performed in 6 intensive care units from January 2001 to December 2005. HAI were identified using standard US Centers for Disease Control and Prevention definitions. Alcohol-based handrub dispensers were installed between February and June 2002.


Total ABHR consumption was 5,794 L (mean, 28.9 L per 1,000 patient-days) and significantly increased over time (+9.2% per year; P < .001). Of 14,516 patients cumulating 166,498 patient-days, 2,398 (16.5%) acquired a total of 3,490 HAI episodes (20.9 per 1,000 patient-days). Incidence densities for central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia, and urinary tract infections were 7.7, 10.6, and 3.6 episodes per 1,000 device-days, respectively. A significant decrease was observed for CLABSI (-12.7% per year; P < .001) with low nurse-to-patient ratio independently associated with infection (odds ratio, 1.11; 95% confidence interval: 1.07-1.16; P < .001).


Improved hand hygiene measured by increased ABHR consumption resulted in CLABSI reduction. Low nurse-to-patient ratio is independently associated with HAI in an upper-middle income country.
