Abstract.
We have investigated prospectively the incidence of urinary tract infection (UTI) in 5320 orthopaedic patients. There were 74 UTIs (1.39%). Enterobacteriaceae was the most frequent etiological agent. Each infection increased the length of stay in hospital by more than 8 days. Statistically independent risk factors for the development of urinary infection were a preoperative stay of more than 4 days, inadequate preoperative preventive measures, central venous catheterization and urinary catheterization. Sex, age, or type of surgery had no statistical influence on the development of infection.
Résumé.
Nous avons étudié prospectivement 5320 patients hospitalisés pendant plus de 2 jours. Les entérobactéries furent les agents étiologiques principaux parmi les 74 infections urinaires (1.39%). L'infection urinaire a prolongé l'hospitalisation de plus de 8 jours. Les facteurs de risque retrouvés pour l'infection urinarie sont: une hospitalisation préopératoire de plus de 4 jours, des mesures préventives préopératoires insuffisantes, la cathéterisation veineuse centrale, et la cathéterisation vésicale. Le sexe, l'âge ou le type de chirurgie n'ont pas montré de signification statistique.
