Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention | We will select 3 intervention sites who are above the median in their frequency of excessive post-procedural antimicrobial use after the 3 urologic procedures of interest, based on each hospital's performance during a 24-month baseline period. We will provide feedback both at baseline and at regular intervals to the 3 intervention sites. At first, we will schedule one-on-one conference calls with urology providers and the antimicrobial stewardship team at each of the 3 intervention sites. These conference calls will include a review of guidelines, a review of the facility's data on excessive post-procedural antimicrobial use for urologic patients, and an anonymous comparison to all other VHA sites. Next, we will prospectively monitor excessive post-procedural antimicrobial use at all 3 sites and the entire VHA for 1 year. Data on hospital-level excessive post-procedural antimicrobial use specific to urologic patients (primary outcome) will be sent electronically to urology providers and the antimicrobial stewardship team at the intervention site every other month via electronic mail. These data will include an anonymous comparison to all other VHA hospitals. | 4 | 525 | EG000 |
| Group 2 | Baseline | Adverse events were measured among patients who underwent a qualifying procedure at the 3 intervention sites prior to implementation of the intervention. This period spanned from 7/1/2020-6/30/2022. | 4 | 1,272 | EG001 |
