Impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional hand hygiene approach in three cities of Colombia

Abstract

To assess the feasibility and effectiveness of the International Nosocomial Infection Control Consortium (INICC) multidimensional hand hygiene (HH) approach in Colombia, and analyze predictors of poor HH compliance. An observational, prospective, interventional, before-and-after study was conducted from May 2003 through September 2010 in 10 intensive care units (ICUs) of six hospitals in three cities. The study was divided into two periods: a baseline and a follow-up period. Observations for HH compliance were done in each ICU during randomly selected 30-min periods. The multidimensional HH approach included: (1) administrative support, (2) supplies availability, (3) education and training, (4) reminders in the workplace, (5) process surveillance, and (6) performance feedback. A total of 13187 opportunities for HH were observed. Overall HH compliance increased from 50% to 77% (relative risk 1.55, 95% confidence interval 1.43-1.68; p=0.0001). Multivariate and univariate analyses showed that several variables were significantly associated with poor HH compliance: males vs. females (67% vs. 77%; p=0.0001), physicians vs. nurses (59% vs. 78%; p<0.0001), and adult vs. pediatric ICUs (76% vs. 42%; p<0.001), among others. Adherence to HH was increased by 55% with the INICC approach. Programs targeted at improving HH in variables found to be predictors of poor compliance should be implemented.
