Abstract

Objective: To evaluate the efficacy of a program to control nosocomial spread of methicillin-resistant Staphylococcus aureus (MRSA). Methods: Analysis of the incidence of infection and contamination due to MRSA in patients admitted to the hospital of Cremona 6 months before and 3 years after the introduction of the guidelines (July 1997). Results: During the 42 months of the study period, on 80705 admissions, 511 cases of MRSA contamination/infection were identified, the incidence being 0.57 cases per 100 admissions. The infection rate dropped from 0.34 (IC95%: 0.25-0.45) in the first 6 months of the study, before the introduction of guidelines, to 0.17 (IC95%: 0.14-0.20) in the following 3 years (p=0.01). Severe infection decreased from 0.18 to 0.1 per 100 admissions, with a 44% decrease (p=0.058), while mild infections dimineshed from 0.16 to 0.07 per 100 admissions (p=0.045). Methicillin resistance among nosocomial isolates of Staphylococcus aureus was reduced from 53% to 35% (p
