We sought to implement a multipronged behavioral intervention to reduce and tailor antibiotic use for 2 common urologic outpatient procedures. This study was a nonblinded intervention study that consisted of a preintervention phase (November 2018-January 2019), an intervention phase (January 2020-December 2020) in which a multipronged behavioral intervention was implemented, and a postintervention phase (January 2021-March 2021). We examined antibiotic use for cystoscopy and transrectal prostate biopsy at 3 separate urologic outpatient clinics. A multipronged behavioral intervention consisted of formal physician education, modification of the electronic health order sets, clinic staff education, literature review, development and introduction of patient questionnaires, and individual audit feedback. The primary outcome was 30-day infections. Secondary outcomes were adherence to the recommended antibiotic protocols, questionnaire completion, and Escherichia coli outpatient antibiograms. A total of 2374 patients underwent 3047 cystoscopies, and 547 patients underwent 559 prostate biopsies. The proportions of cystoscopy patients receiving antibiotic prophylaxis and prostate biopsy patients receiving augmented antibiotic prophylaxis decreased 33% and 35%, respectively. The odds of postcystoscopy infection were not different between the preintervention and intervention phases and were lower in the postintervention phase. The odds of postbiopsy infection were not changed between the preintervention and intervention phases or between the preintervention and postintervention phases. Implementing a multipronged behavioral intervention reduced and tailored antibiotic use without an increase in 30-day infections. These findings suggest that outpatient antibiotic stewardship and facilitating rapid adoption of guidelines can be accomplished via this approach.

Live donor nephrectomy (LDN) is performed by various specialty surgeons, including urologists, general surgeons, and transplant surgeons. However, national practice patterns and outcomes associated with surgeon specialty have not been previously explored. Here, we investigate surgeon specialty trends, perioperative complications, hospital length of stay, cost, and charge for LDN according to surgeon specialty. Patients who underwent LDN from 2000 to quarter 1 of 2020 were identified in the Premier Healthcare Database. Associations between physician specialty and 3-month complications, hospital length of stay, institutional cost, and patient charge for LDN procedures were examined using multivariable regression. We identified 11,418 patients who underwent LDN. Of these cases, 3387 (29.7%) were performed by urologists, 3127 (27.4%) by transplant surgeons, 3928 (34.4%) by general surgeons, and 976 (8.5%) by other specialties. In 2000, urologists performed 35.92% of LDNs, decreasing to 18.91% by 2019 (P < .001 for trend). In the last 5 years, we found no significant difference in complications or length of stay according to surgeon specialty. LDNs performed by a urologist ($57,289, 95% CI $49,292-$66,582) were associated with lower patient charges than those performed by a general surgeon ($68,501, 95% CI $59,090-$79,412) or transplant surgeon ($62,639, 95% CI $53,993-$72,670). From 2000 to 2019, the proportion of LDNs performed by urologists significantly decreased, while the proportion for transplant surgeons significantly increased, with no significant differences in complications or length of stay across specialties. However, surgeries performed by urologists cost hospitals less and had lower charges for patients.
