Evaluate the effect of an intervention on the rate of nosocomial infections (NI) produced by multiresistant microorganisms in the Intensive Care Units.A study was conducted before and after an intervention in two ICUs to control an outbreak of multiresistant Acinetobacter baumanii (MRAB). During the outbreak (from 22-12-06 to 12-2-07) the wards were closed and both the wards and the equipment of both ICUs were cleaned and disinfected. A microbiological sampling was also made. The nosocomial infection rate density of the multiresistant microorganisms was compared between hospitalized patients: preintervention (1-3-2006 to 15-12-2006) and postintervention (1-3-2007 to 15-12-2007). To certify if there were any statistically significant differences between them, a rate ratio (RT) was calculated with a 95% confidence interval. The level of statistical significance was established at p0.05. We stratified per unit, per type of microorganism and location of the infection.The global NI incidence rate for multiresistant microorganisms significantly declined after the interventions in both units (RT: 1.83, 95% CI: 1.34-2.50), p0.005. A significant decrease was also observed on the NI incidence rate for the following microorganisms: P. aeruginosa (RT: 2.36, 95% CI: 1.41-3.96), Enterobacter BLEE (RT: 2.31, 95% CI: 1.11-4.82) and S. maltophilia (RT: 2.77, 95% CI: 1.10-6.99). In regards to the infection location, a significant decrease in respiratory infection rates was observed (RT: 1.96, 95% CI: 1.29-2.99).The intervention conducted to control the MRAB outbreak was effective in reducing the NI incidence of multiresistant microorganisms. |
