Does Rounding Order Bias Discharge Efficiency? Predictors of Discharge Timing on an Academic Urology Service.

ABSTRACT: No previous works have analyzed whether the order in which surgical teams see patients on morning rounds affects discharge efficiency at teaching hospitals. We obtained perioperative urologic surgery timing data at our academic institution from 2014 to 2019. We limited the analysis to routine postoperative day 1 discharges. Univariate and multivariate analyses were performed to determine whether various hospital and patient factors were associated with discharge timing. We analyzed 1,494 patients. Average discharge order time was 11:22 a.m. and hospital discharge 1:24 p.m. Univariate regression revealed earlier discharge order time for patients seen later in rounds by 4 minutes per sequential room cluster (p = .013) and by 12 minutes per cluster when excluding short-stay patients. Multivariate analysis revealed discharge order placement did not vary significantly by rounding order. However, time of hospital discharge did (p < .001), likely due to speed of discharge in the designated short-stay units. Attending physician was the most consistent predictor in variations of discharge timing, with statistical significance across all measured outcomes. Patients seen later in rounding progression received earlier discharge orders, but this relationship does not remain in multivariate modeling or translate to earlier discharge. These findings have helped guide quality improvement efforts focused on discharge efficiency.

Significant financial differences of chemical and surgical androgen deprivation in a contemporary cohort.

Background: Androgen deprivation therapy (ADT) remains a cornerstone of treatment for advanced prostate cancer. Few men elect for surgical castration via bilateral orchiectomy. We sought to compare the relative difference in financial charges between chemical and surgical ADT in men. Methods: Billing data was obtained for patients with metastatic prostate cancer receiving chemical ADT and who had bilateral orchiectomy from 2014-2019. Men had chosen intervention based on personal preference. We compared charges of ADT administration for chemical ADT and overall charges for bilateral orchiectomy. We determined the time chemical ADT patient charges surpassed those of surgical charges, as well as the net present value (NPV) of hypothetical savings for electing surgery over various ADT agents. Results: One hundred and thirty-seven patients receiving chemical ADT and 7 patients who had undergone bilateral orchiectomy were analyzed. Median and mean surgical charges were $13,000. By 38 weeks following treatment initiation, 50% of chemical ADT patients had surpassed surgical charges, with 95% at 2 years. The NPV in savings for a median patient varied between ADT agent and was highest at $167,000 for leuprolide. Conclusions: In less than a year, the median chemical ADT patient charges were greater than surgical castration. The NPV of electing surgery over ADT was the highest with leuprolide. Despite under-utilization, surgical castration remains a medically appropriate and cost-effective option for permanent ADT.

Association between the lengths of excised obstructed vas deferens segments at the time of vasovasostomy and surgical outcomes.

OBJECTIVE: This study aimed to determine whether the length of the excised obstructed vas deferens at vasovasostomy (VV) performed for fertility is associated with semen parameters and/or pregnancy outcomes postoperatively. MATERIAL AND METHODS: The patients who underwent a VV at our institution from September 2004 to December 2018 were contacted via questionnaire and a chart review was performed. Linear and logistic regression models were used to determine the associations between the length of the obstructed vas deferens removed and postoperative outcomes including sperm concentration, motility, and successful pregnancy after reversal. RESULTS: A total of 83/170 questionnaires were returned. After exclusions, a total of 35 patients were included for analysis. The mean age of the patients at the time of surgery was 40.1 years and the mean time since vasectomy 9.3 years. The mean length of the obstructed vas deferens removed during VV was 2.25 cm. The longer the vas deferens segments removed, the more significant was the increase in sperm motility at 3 and 9 months postoperatively (p=0.011 and 0.008, respectively), but decreased sperm motility at 6 months (p=0.029). In 75.9% of the patients, sperm was present postoperatively, 23.2% achieved pregnancy through natural conception, and 55.8% achieved pregnancy using assisted reproductive techniques. There was no significant relationship between the length of the vas deferens removed and sperm concentration or pregnancy achieved after surgery. CONCLUSION: In this cohort, the length of the excised obstructed vas deferens at VV was associated with improved sperm motility at 3 and 9 months postoperatively but not with pregnancy outcomes.

Treatment Setting Influences Treatment Modality for Urinary Stone Disease.

OBJECTIVE: To determine whether selection of treatment modality for urinary stone disease differs between primary and outreach healthcare centers, and if patient rurality predicts treatment modality. METHODS: We retrospectively evaluated Extracorporeal shock wave lithotripsy (ESWL) and ureteroscopy (URS) procedural data from the Iowa Office of Statewide Clinical Education Programs (OSCEP) and Iowa Hospital Association (IHA) databases from 2007 to 2014. Geographical data was used to analyze travel metrics and patient proximity to sites of stone treatment. Rural-urban commuting area (RUCA) codes were used to characterize patient rurality. Chi-square tests and t tests were used to compare ESWL and URS patients, and multilevel logistic regression model was used to assess influence of treatment setting on surgical modality. RESULTS: A total of 18,831 stone procedures were performed by urologists in Iowa on patients from Iowa (10,495 URS; 8336 ESWL). Around 2630 procedures occurred at outreach centers. Ureteroscopy comprised 59.7% of procedures at primary centers, but only 31.2% at outreach centers. On multilevel analysis, outreach location was associated with 2.236 OR toward ESWL (P <.001). Individual physician treatment patterns accounted for 32% of treatment variation. Patient rurality was not significantly associated with treatment modality as an independent factor (P = .879). CONCLUSIONS: Wide variation exists in urolithiasis treatment modality selection between outreach and primary centers. Outreach locations perform a significantly higher frequency of ESWL compared to URS, and much of the variation in treatment selection (32%) arises from individual physician practice patterns.

Pilot Study to Determine Optimal Stent Duration Following Ureteroscopy: Three versus Seven days.

BACKGROUND/AIMS: Many providers elect to place a stent following ureteroscopy for nephrolithiasis, but little data exists on the optimal duration to leave a stent. We sought to determine whether there are any differences in post-operative outcomes for patients with a 3 versus 7-day stent following ureteroscopy. METHODS: We retrospectively reviewed 247 patients who underwent unilateral ureteroscopy with lithotripsy, 79 of whom removed a stent with an extraction string at 3 or 7 days post-operatively. These 2 groups were compared with regard to demographic information, pre-operative variables, and post-operative outcomes. RESULTS: Of all patients, 33% experienced a post-procedure related event (phone call, extra clinic visit, and emergency department visit) within 30 days of their procedure, 39% of 3-day stent patients compared to 21% of 7-day patients (p = 0.11). Within the 3 days following stent removal, 3-day stent patients were significantly more likely to have a post-procedure related event than 7-day patients (23 vs. 3%, p = 0.026). CONCLUSION: One third of patients with a post-operative ureteral stent will seek medical care in the 30 days following ureteroscopy. Leaving a stent for 3 versus 7 days may lead to worse outcomes with regard to post-operative events and fank pain.

Increasing the size of ureteral access sheath during retrograde intrarenal surgery improves surgical efficiency without increasing complications.

PURPOSE: To directly compare intraoperative and post-operative outcomes and complications between three groups undergoing ureteroscopy: no ureteral access sheath, 12/14 Fr and larger 14/16 Fr ureteral access sheaths (UAS). METHODS: We retrospectively reviewed demographic, pre-operative, intraoperative, and post-operative data of 257 patients who underwent ureteroscopy for nephrolithiasis by a single surgeon from January 2013 through July 2015. Patients were separated into three groups: no UAS, a 12/14 Fr UAS, or 14/16 Fr UAS. Outcomes included differences in stone-free rate, post-procedure-related events (PRE), ureteral injury rate (measured by early post-operative hydronephrosis), and post-operative complications. RESULTS: A UAS was used in 65.4% (168/257) patients, with 73.8% (124/168) utilizing a 12/14 Fr UAS and 26.2% (44/168) utilizing a 14/16 Fr UAS. Those patients in whom a 14/16 Fr UAS was employed had greater stone burden compared to the 12/14 Fr UAS group (180.8 ± 18.0 vs. 104 ± 9.1 mm2, p < 0.001). When comparing 12/14 Fr and 14/16 Fr ureteral access sheaths, there was no significant difference in ureteral injury rate, complications (10.5 vs. 11.4%, respectively; p = 0.87), or overall stone-free rate (78.1 vs. 81.3%, p = 0.70). The mean amount of stone burden treated per minute of operative time was more than 30% higher in the 14/16 Fr UAS group compared to 12/14 Fr UAS group (2.11 vs. 1.62 mm2/min; p = 0.01). CONCLUSION: The use of a 14/16 Fr UAS allows for similar stone-free rate and improved operative efficiency with no increased risk of ureteral injury or post-operative complications when compared to the 12/14 Fr UAS.

Novel Management of Anastomotic Disruption and Persistent Hematuria Following Robotic Prostatectomy: Case Report and Review of the Literature.

Vesicourethral anastomosis leaks are not uncommon following radical prostatectomy. We present a case of a 59-year-old male who presented to our ED with hematuria, abdominal pain, and clot retention 17 days after a robotic-assisted laparoscopic prostatectomy. A 50% vesicourethral disruption was ultimately managed endoscopically and with hemostatic agents. At 9-month follow-up he is fully continent with normal erectile function. Vesicourethral leaks can typically be managed conservatively with gentle traction and prolonged catheterization. Persistent hematuria can complicate management, and hemostatic agents may allow for completely endoscopic management with minimal morbidity as seen in this case.

Pushing Stones Uphill: Why Patients Are Lost to Follow-Up After Uncomplicated Ureteroscopy.

INTRODUCTION: We sought to determine the rate of and factors associated with patient nonadherence to prescribed follow-up after uncomplicated ureteroscopy. MATERIALS AND METHODS: The records of 247 consecutive patients who underwent ureteroscopy at a tertiary referral center from November 2010 to February 2016 were reviewed. Bivariate and multivariate analyses were performed to determine the impact of demographic, procedural, socioeconomic, and environmental factors on the rate of compliance with secondary prevention counseling. RESULTS: Forty-five patients (18.5%) were lost to scheduled follow-up for secondary prevention counseling after ureteroscopy. Lost to counseling rates were broad based and not associated with traditional predictors of poor follow-up such as age, gender, marital status, and distance traveled. On multivariate analysis, compared with those using commercial insurance, patients with Medicare (odds ratio [OR] for follow-up 0.48, 95% confidence interval [CI] 0.21, 1.1 p = 0.095) and Medicaid (OR for follow-up 0.25, 95% CI 0.1, 0.6, p < 0.001) were less likely to be adherent to prescribed follow-up. CONCLUSIONS: Nearly one in five patients will be lost to follow-up for secondary prevention counseling after ureteroscopy. Lack of follow-up may prevent the diagnosis of postoperative complications and limit the ability to counsel patients on stone prevention. Efforts to improve follow-up following ureteroscopy should focus on including more postoperative counseling in the preoperative period and a more individualized approach to specific patient populations, particularly those with a lower socioeconomic status.
