Impact of an evidence-based intervention on urinary catheter utilization

Catheter-associated urinary tract infections (CAUTI) are a well-known complication of urinary tract catheterization, with rates ranging from 0.2-4.8 per 1,000 catheter days. The aim of this study was to decrease urinary catheterization and consequently catheter-associated urinary tract infections (CAUTI) and non-infectious complications.

We included 25,880 patients [13,171 before the intervention (August-October 2016) and 12,709 after the intervention (August-October 2017)]. Catheter utilization dropped from 23.7% to 21.0% (p=0.001), and catheter-days per 100 patient-days from 17.4 to 13.5 (p=0.167). CAUTI remained stable on a low level with 0.02 infections per 100 patient-days (before) and 0.02 infections (after), (p=0.98). Measuring infections per 1,000 catheter-days, the rate was 1.02 (before) and 1.33 (after), (p=0.60). Non-infectious complications dropped significantly, from 0.79 to 0.56 events per 100 patient-days (p<0.001), and from 39.4 to 35.4 events per 1,000 catheter-days (p=0.23). Indicated catheters increased from 74.5% to 90.0% (p<0.001). Reevaluations increased from 168 to 624 per 1,000 catheter-days (p<0.001).

In this before/after intervention study of urinary catheter utilization, a straightforward bundle of three evidence-based measures (providing a catheter indication list, promoting daily catheter evaluation, and teaching state-of-the-art catheter insertion) reduced catheter utilization and led to increases in indicated urinary catheters and daily evaluations. The intervention had an impact on non-infectious complications, whereas the CAUTI rate remained on a low level.The next step is planning the national roll-out of both the surveillance module and the intervention bundle, the components of which have been made available to the public (surveillance module, intervention bundle)
