[Inquiry into the incidence of nosocomial infections and evaluation of the transmission of methicillin-resistant Staphylococcus aureus in an orthopedic surgical unit].
Nosocomial infections are an important cause of morbidity and mortality. Methicillin resistant Staphylococcus aureus (MRSA) is often the severe causal agent in this kind of infections. In order to evaluate risk factors for nosocomial infections and nasal MRSA carriage, an incidence study was carried out on patients hospitalized in an orthopaedic surgery department in Boucicaut Hospital (Paris). This study was carried out over a five month period. Data of all the patients who stayed more than two days in the unit were collected in medical and nursing records. Nasal swab specimens were taken at the admission of each patient included in order to screen nasal MRSA carriers. Statistical analysis were performed using Epi Info software version 6.0. A total of 451 patients were included in the study. Nosocomial infections incidence rate was 11.5%. Risk factor significantly associated with nosocomial infection was high wound containation classes III and IV (Altemeier). Incidence rate of MRSA carriage was 3.1%. A previous hospitalization in a general hospital 6 months before an admission at Boucicaut Hospital was the only risk factor identified. According to this, these patients, when they are admitted, are proposed to be preventely isolated awaiting their microbiological results.
