Implementing Change Through an Outpatient Antibiotic Stewardship Program.

INTRODUCTION: We sought to implement a multipronged behavioral intervention to reduce and tailor antibiotic use for 2 common urologic outpatient procedures. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

"Factors influencing readmission patterns following radical cystectomy: An analysis of social determinants and discharge outcomes".

INTRODUCTION AND OBJECTIVES: Radical cystectomy readmission rates remain high, with around 25% of patients readmitted to index and nonindex hospitals in 30 days. Nonindex readmissions have been associated with poorer outcomes, including longer lengths of stay and higher mortality rates. This study aimed to examine the associations of social factors (e.g., sex, race, socioeconomic status, insurance type, and resident location) on readmission to index versus nonindex hospitals and discharge disposition. METHODS: We conducted a population-based retrospective study using the Pennsylvania Cancer Registry (PCR) to identify patients diagnosed with nonmetastatic muscle-invasive bladder cancer who underwent radical cystectomy in Pennsylvania between 2010 and 2018. Readmitted patients were identified using the Pennsylvania Health Care Cost Containment Council data (PHC4). The primary outcome was readmission location (i.e., index or nonindex hospital) following radical cystectomy. We used chi-square tests for categorical variables, Wilcoxon rank sum test for continuous variables, multivariable logistic regression model to assess predictors of being readmitted to an index hospital and calculating the predicted probability of being admitted to an index hospital depending on discharge disposition. RESULTS: A total of 517 patients were readmitted within 30-days after radical cystectomy. The majority of readmissions were index readmissions (83%). Median readmission hospital stay was 4 days (interquartile range [IQR] 4) for index and 5 days (IQR 7) for nonindex hospitals, P = 0.01. Patients readmitted to index hospitals had fewer comorbidities (median weighted Elixhauser Comorbidity Index 2 (IQR 2)) and lived in urban areas (89%). Discharge with home care was associated with a higher odds of index readmission (odds ratio, [OR] 2.40; 95% confidence interval, [CI] 1.25-4.52). CONCLUSIONS: Patients residing in urban areas and with fewer comorbidities were more likely to be readmitted to index hospitals than nonindex hospitals. Socioeconomic status and insurance type did not correlate with the type of readmission. Finally, being discharged with home health care was found to be a predictor of readmission to an index hospital.

Using a Multi-pronged Behavioral Intervention to Standardize Antibiotic Prophylaxis at the Time of Foley Catheter Removal After Radical Prostatectomy.

OBJECTIVE: To identify antibiotic prescribing patterns at the time of foley catheter removal after radical prostatectomy and implement a multi-pronged behavioral intervention to standardize antibiotic use. METHODS: This was a single-institution study examining the prescribing of antibiotics at the time of foley catheter removal after radical prostatectomy. Pre-intervention data were collected retrospectively to establish baselines for antibiotic prescribing, patient characteristics, and urinary tract infection rates. A single dose of an oral antibiotic taken at the time of foley catheter removal was recommended as the standard antibiotic protocol. A multi-pronged behavioral intervention was used to encourage compliance with our protocol. Adherence to the protocol, quantity of antibiotics prescribed, and rate of urinary tract infection were recorded prospectively. Durability of the intervention was evaluated during a post-intervention phase. RESULTS: A total of 416 patients and 6 surgeons were included in the study. Accordance with the standardized antibiotic protocol was 59% in the pre-intervention phase and 91% in the intervention phase (P = .03). No patients in the intervention or post-intervention phase were prescribed more than one dose of an antibiotic. The rate of urinary tract infection did not differ across the study phases. CONCLUSION: Implementation of a multi-pronged behavioral intervention resulted in a high rate of surgeon compliance with a standardized antibiotic protocol. This led to a significant reduction in antibiotic use with no change in the rate of urinary tract infection after foley catheter removal after radical prostatectomy.

Utilizing a Questionnaire to Implement a Risk-based Antibiotic Prophylaxis Protocol for Transrectal Prostate Biopsy.

OBJECTIVE: To develop and evaluate a risk-based antibiotic prophylaxis protocol for patients undergoing transrectal prostate biopsy. METHODS: We created a risk-based protocol for antibiotic prophylaxis before transrectal prostate biopsy. Patients were screened for infection risk-factors with a self-administered questionnaire. The protocol was implemented from January 1, 2020 to March 31, 2020. We compared patient risk-factors, antibiotic regimens, and 30-day infection rates for patients undergoing transrectal prostate biopsies during the intervention and for a 3-month period before the intervention. RESULTS: There were 116 prostate biopsies in the preintervention group and 104 in the intervention group. Although there was no significant difference in the number of high-risk patients between the 2 groups (48% vs 55%; P = .33), the percentage of patients treated with augmented prophylaxis decreased from 74% to 45% (P = 0.03). The duration of antibiotic administration and the median number of doses prescribed also decreased significantly. Despite significant decreases in antibiotic use, there were no differences in infection rates (5% vs 5%; P = .90) or sepsis rates (1% vs 2%; P = .60). CONCLUSION: We developed a risk-based protocol for prophylactic antibiotics before prostate biopsy. The protocol was associated with less antibiotic use but did not lead to an increase in infectious complications.

Obstructing ureteral calculus causing massive hydronephrosis in a renal allograft.

Nephrolithiasis is a rare complication of renal transplantation. Patients with an obstructing calculus in a renal allograft often lack the usual renal colic symptoms, and therefore present with atypical symptoms. Treatment of obstructing calculi is imperative to prevent renal allograft failure and other complications. We report the case of a 46-year-old man who presented 28 years after renal transplant with renal failure and massive hydronephrosis secondary to an obstructing calculus.

Contemporary best practice in the management of staghorn calculi.

Staghorn calculi are complex renal stones that occupy the majority of the renal collecting system. These stones are associated with high morbidity and can lead to recurrent urinary tract infections, urosepsis, renal deterioration, and death if left untreated. Managing patients with staghorn calculi can be challenging. Fortunately, advances in technology and endourology techniques have enabled urologists to effectively treat these stones with minimal morbidity to the patient. This article describes the contemporary best practices in the initial evaluation, management, and follow up of patients with staghorn calculi to help the practicing urologist navigate this complex condition.

Cowper's Gland Syringocele.

Cowper's gland syringoceles are rare cystic dilations of the Cowper's gland duct. They are typically diagnosed in childhood but occasionally occur in adults. We report the case of a 28-year-old man who presented with a painful perineal and inferior scrotal mass and was found to have a large Cowper's gland syringocele extending into the scrotum associated with a scrotal abscess. Treatment consisted of surgical excision. The magnetic resonance imaging findings of this case are described.

Paratesticular fibrous pseudotumor.

We present a rare case of fibrous pseudotumor of the tunica vaginalis. Discussion includes identification, histopathologic findings and management. Proper understanding and preoperative identification of this benign disease allows for an organ-sparing surgical approach.

Concept Mapping as a Method to Engage Patients in Clinical Quality Improvement.

Patient engagement has become a primary care research and practice priority. Little guidance exists, however, on how best to engage patients in primary care practice improvement, or how to measure the impact of their engagement. We present an overview of group concept mapping as a method for engaging patients in primary care practice improvement. We detail the group concept mapping process as a tool for use in primary care practice improvement, research, and evaluation, and we present resources to enable researchers and practice leaders to use this tool in practice improvement. To illustrate the method, we present a practice-based quality improvement project conducted with patients and staff at a large urban academic primary care practice.
