Abstract
in English, French

The aim of this prospective study was to determine the effect of screening for methicillin-resistant Staphylococcus aureus (MRSA), in patients undergoing total hip and knee replacements, on reducing hospital-acquired infections and the length of hospital stay. We included 395 patients admitted to the elective orthopaedic ward for hip and knee replacements (knee 210; hip 185) from 16 October 2000 to 15 October 2001. Group 1 included 164 admissions before 16 April 2001 when MRSA swabs were not compulsory. Group 2 included 231 admissions after 16 April 2001 when axillary, nasal and groin swabs had to be negative for MRSA. Four patients in group 1 had post-operative MRSA infection compared with none in group 2. The mean length of hospital stay decreased significantly from 10.43 days +/- SD 4.2 days in group 1 to 9.47 days +/- SD 2.6 days in group 2. There was a significant reduction in the incidence of hospital-acquired infections following the introduction of pre-admission screening.

Le but de cette étude prospective était de déterminer l’effet du dépistage du Staphylocoque Aureus Méthicilline Résistant (MRSA) chez des patients devant subir une prothèse de hanche ou de genou, sur la réduction des infections nosocomiales et la durée du séjour hospitalier. Nous avons inclus 395 malades admis pour remplacement prothétique de la hanche et du genou (genou 210 / Hanche 185) du 16 octobre 2000 au 15 octobre 2001. Le groupe 1 a inclus 164 admissions avant le 16 avril 2001 quand les écouvillonnages MRSA n’étaient pas obligatoires. Le groupe 2 a inclus 231 admissions après le 16 avril 2001 quand l’écouvillonnage axillaire, nasal et inguinal devait être négatif pour le MRSA. Cinq malades du groupe 1 ont eu une infection MRSA postopératoire , comparé à l’absence d’infection dans le groupe 2. La durée moyenne de séjour a diminué de 10.43 jours (±SD 4.2 j) dans le groupe 1 à 9.47 jours (±SD 2.6 j ) dans le groupe 2. Il y avait une réduction significative de la fréquence des infections acquises à l’hôpital grâce au dépistage avant l’admission.
