Impact of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Hand Hygiene Approach During 3 Years in 6 Hospitals in 3 Mexican Cities.

Abstract

To evaluate the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional hand hygiene (HH) approach in Mexico, and analyze predictors of poor HH compliance. From June 2002 to April 2006, we conducted a prospective, observational, before-and-after study in 8 intensive care units (ICUs) from 6 hospitals in 3 cities of Mexico. The approach included administrative support, availability of supplies, education and training, reminders in the workplace, process surveillance, and performance feedback. A total of 13,201 observations for HH opportunities were done in each ICU, during randomly selected 30-minute periods. Overall, HH compliance increased from 45% to 79% (95% confidence interval [CI], 69.1-86.5; P = 0.01). Univariate and multivariate analyses showed that several variables were significantly associated with poor HH compliance: males versus females (61% versus 66%; 95% CI, 0.91-0.96; P = 0.0001), physicians versus nurses (62% versus 67%; 95% CI, 0.91-0.97; P = 0.0001), and adult versus neonatal ICUs (67% versus 54%; 95% CI, 0.79-0.84; P = 0.0001), among others. Hand hygiene programs should focus on variables found to be predictors of poor HH compliance.
