Enquête de prévalence sur le sondage vésical dans un centre hospitalo-universitaire

Abstract

Urinary tract infection is the most common healthcare-association infection, especially because of urinary catheter. We evaluated our practices concerning catheter insertion and management in our institution. We conducted a single-centre descriptive cross-sectional study during 1week in September2014 in all adult departments. We noted prevalence, indications, length, management of urinary catheter (UC) and symptomatic catheter-associated urinary tract infections (SCAUTI). Amongst 1046patients audited, 125 (12%) had UC. The mean age was 72years (64.8-79.2). UC prevalence was higher in surgical (88%) and medical (87%) intensive care, urology (50%), geriatrics (18%) and long-term care (18%) departments. The average catheterisation length was 7.8days (3.8-11.8); it was shorter in surgery than in medicine departments (3.6 vs 9.7days, P<0.001). Catheters were present for more than 4days in 60% of the cases. Acute urinary retention was the most frequent indication (59%), significantly more in medical than surgical departments (75% vs 26%). Others indications were perioperative (17%), diuresis monitoring (12%), strict immobilization (4%) and unnecessary indications or staff comfort (4%). A SCAUTI was present in 10% of cases, mostly in medicine department (30% vs 8%). The prevalence of our institution is higher than the national prevalence (8.1%), but still below the European average (17.2%). Control of the risk of CAUTI requires compliance with UC appropriate indications, UC management, and prompt removal of unnecessary UC. 4.
