【 摘 要 】

BackgroundIndwelling urinary tract catheters (UTC) are a well-known risk factor for urinary tract infections (UTI). Because geriatric patients are at high risk of infection, an intervention with a focus on appropriate and minimal UTC use was introduced in 4 acute care geriatric wards.MethodsBetween 11/2018 and 1/2020, unit-based data on UTC use and nosocomial UTI was collected in accordance with the methods of the German national surveillance system KISS. From 6/2019 to 1/2020, a champion-led intervention was implemented which focused on: (i) feedback of surveillance data, (ii) education and training in aseptic UTC insertion and maintenance, (iii) HCW’s daily assessment of UTC necessity based on a checklist and (iv) timely removal of unnecessary UTCs. UTC use, incidence, and incidence densities for catheter-associated UTI (CAUTI) were calculated before and during the intervention. In addition, we analyzed adherence to a scheduled daily assessment of UTC necessity. Rate ratios (RR) with 95% confidence intervals (95%CI) were calculated. Differences based on the quality of checklist completion were evaluated using the Kruskal Wallis test.ResultsWe analyzed the data of 3,564 patients with a total 53,954 patient days, 9,208 UTC days, and 61 CAUTI. Surveillance data showed a significant decrease in the pooled UTC utilization rate from 19.1/100 patient days to 15.2/100 patient days (RR = 0.80, 95%CI 0.77–0.83, p < 0.001). CAUTI per 100 patients dropped from 2.07 to 1.40 (RR = 0.68, 95%CI 0.41–1.12, p = 0.1279). Overall, 373 patients received a UTC during the intervention. Of those patients 351 patients had an UTC ≥ 2 days. The analysis of these patients showed that 186 patients (53%) received a checklist as part of their chart for daily evaluation of UTC necessity. 43 (23.1%) of the completed checklists were of good quality; 143 (76.9%) were of poor quality. Patients in the group whose checklists were of good quality had fewer UTC days (median 7 UTC days IQR (3–11)) than patients whose checklists were of poor quality (11 UTC days IQR (6–16), p = 0.001).ConclusionWe conclude that a champion-led, surveillance-based intervention reduces the use of UTC among geriatric patients. Further research is needed to determine to what extent the use of checklists in daily medical UTC assessment affects the prevention of CAUTI. The fact that patients whose checklists were completed well had fewer UTC days should encourage a conscientious and thorough daily review of the need for UTC.
