Table 1, Chapter 9Description of outcomes evaluated (adapted from the prior meta-analysis19)

Measures of Catheter-Associated Urinary Tract Infection (Cauti) DevelopmentNumber of CAUTI episodes per 1,000 catheter-days was recorded and a rate ratio was calculated to compare pre- vs. post-intervention. When rates of both asymptomatic and symptomatic CAUTI were reported separately,20 the rates of symptomatic CAUTI were used for the meta-analysis.19
Cumulative risk of CAUTI during hospitalization (i.e., the percentage of patients who developed CAUTI) was also extracted for each study, and a risk ratio was calculated to compare risks before and after the intervention for the meta-analysis.19
Measures of Urinary Catheter UseMean number of days of urinary catheter use per patient was recorded before and after the intervention, and a standardized mean difference (SMD) was calculated to compare the two groups for the meta-analysis.19
Percentage of patient days in which the catheter was in place was calculated before and after the intervention, and a standardized mean difference (SMD) was determined for each study for the meta-analysis.19
Daily catheter prevalence, defined as the number of patients with catheters in place during a specific time period, is reported for some of the more recent studies.
Need for Catheter ReplacementRe-catheterization need was extracted as the number and percent of patients who required replacement of a catheter after prior removal of an indwelling catheter.

The table in Appendix D summarizes the intervention studies described in this review, including study designs, patient populations, and the interventions employed to avoid unnecessary catheter placement or to prompt catheter removal.
