A study to determine whether the use of a preconnect urinary catheter system reduces the incidence of nosocomial urinary tract infections

Abstract

Nosocomial urinary tract infection (NUTI) is a common problem in the UK and is often related to the use of urinary catheters. In the UK urinary catheters account for approximately 25% of all healthcare associated infections and can have a considerable financial burden on the health service. Bacteria may gain entry into the bladder of a catheterised patient via the intra-luminal route especially if accidental disconnection arises. A prospective study was undertaken to determine the NUTI rates in patients using a preconnected catheter system compared to a traditional bag and catheter system on three medical wards. A total of 205 patients were included in the study. The catheter-associated urinary tract infection rate (CAUTI) in the baseline was 37.8 per 1,000 catheter days and 22.4 per 1,000 catheter days in the intervention group. The rates of CAUTI were 41% lower in the intervention group. The data in this sample group suggests the use of the preconnected catheter offers some protection against infection. The use of the preconnected system is a new concept in the UK and further studies are required to evaluate its effectiveness. The results from this study suggest their use may help to reduce the risk of CAUTI in certain clinical areas.
