Daily Ecological Momentary Assessments of Pain and Ability to Work After Ureteroscopy and Stenting.

Introduction: Ureteral stents can cause significant patient discomfort, yet the temporal dynamics and impact on activities remain poorly characterized. We employed an automated tool to collect daily ecological momentary assessments (EMAs) regarding pain and the ability to work following ureteroscopy with stenting. Our aims were to assess feasibility and better characterize the postoperative patient experience. Materials and Methods: As an exploratory endpoint within an ongoing clinical trial, patients undergoing ureteroscopy with stenting were asked to complete daily EMAs for 10 days postoperatively or until the stent was removed. Questionnaires were distributed through text messages and included a pain scale (0-10) and a single item from the validated Patient-Reported Outcomes Measurement Information System Ability to Participate in Social Roles and Activities instrument, as well as days missed from work or school. Results: Among the first 65 trial participants, 59 completed at least 1 EMA (overall response rate 91%). Response rates were >85% for each time point through postoperative day (POD)10. Median respondent age was 58 years (interquartile range [IQR] 50-67), and 56% were female. Stones were 54% renal and 46% ureteral, with a median diameter of 9 mm (IQR 7-10). Median stent dwell time was 7 days (IQR 6-8). Pain scores were highest on POD1 (median score 4) and declined on each subsequent day, reaching a median score of 2 on POD5. Sixty-three percent of patients on POD1 reported that they had trouble performing their usual work at least sometimes, but by POD5, this was <50% of patients. Patients who work or attend school reported a median of 1 day missed (IQR 0-2). Conclusions: An automated daily EMA system for capturing patient-reported outcomes was demonstrated to be feasible with sustained excellent engagement. Patients with stents reported the worst pain and interference with work on POD1, with steady improvements thereafter, and by POD5, the majority of patients had minimal pain or trouble performing their usual work. This work is associated with a registered clinical trial [NCT05026710].

Improving the Quality of Upper Urinary Tract Stone Surgery: External Validation of a Statewide Collaborative's Efforts to Reduce Emergency Department Visits After Ureteroscopy.

PURPOSE: The ROCKS (Reducing Operative Complications from Kidney Stones) program in MUSIC (Michigan Urological Surgery Improvement Collaborative) was created to optimize ureteroscopy outcomes. Through data collection, distribution of reports, patient education, and standardization of medication, post-ureteroscopy emergency department visits in Michigan have declined. It is unclear whether this is because of statewide quality efforts or due to national trends. We therefore sought to understand emergency department visit rates in Michigan compared to a national data set. MATERIALS AND METHODS: We compared the MUSIC ROCKS clinical registry in Michigan against a national cohort, Optum's de-identified Clinformatics Data Mart, from 2016-2021 (excluding Michigan). We identified patients who underwent ureteroscopy and the proportion who had a postoperative emergency department visit within 30 days. Emergency department rates were modeled over time, adjusting for age, gender, comorbidity, and ureteral stenting. RESULTS: We identified 24,688 patients in MUSIC ROCKS and 99,340 in the Clinformatics Data Mart database who underwent ureteroscopy. The risk-adjusted emergency department visit rate in MUSIC ROCKS significantly declined over the study period (10.5% in 2016 to 6.9% in 2021, P < 0.001) while the mean emergency department visit rate in the Clinformatics Data Mart cohort was 9.9% and did not change over time (9.6% in 2016 to 10% in 2021). Comparing emergency department visits between the cohorts, the MUSIC ROCKS rate significantly declined relative to the Clinformatics Data Mart (P < 0.001) over the study period. CONCLUSIONS: Postoperative emergency department visit rates in Michigan have declined significantly after ureteroscopy since the establishment of MUSIC ROCKS. This decline outpaced national rates, providing evidence that systematic quality initiatives can improve urological care.

Real-world Practice Stone-free Rates After Ureteroscopy: Variation and Outcomes in a Surgical Collaborative.

BACKGROUND: Studies assessing the stone-free rate (SFR) after ureteroscopy are limited to expert centers with varied definitions of stone free. Real-world data including community practices related to surgeon characteristics and outcomes are lacking. OBJECTIVE: To evaluate the SFR for ureteroscopy and its predictors across diverse surgeons in Michigan. DESIGN, SETTING, AND PARTICIPANTS: We assessed the Michigan Urological Surgery Improvement Collaborative (MUSIC) clinical registry for patients with renal or ureteral stones treated with ureteroscopy between 2016 and 2021 who had postoperative imaging. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Stone free was defined as no fragments on imaging reports within 60 d entered by independent data abstractors. Factors associated with being stone free were examined using logistic regression, including annual surgeon volume. We then assessed variation in surgeon-level SFRs adjusted for risk factors. RESULTS AND LIMITATIONS: We identified 6487 ureteroscopies from 164 surgeons who treated 2091 (32.2%) renal and 4396 (67.8%) ureteral stones. The overall SFRs were 49.6% (renal) and 72.7% (ureteral). Increasing stone size, lower pole, proximal ureteral location, and multiplicity were associated with not being stone free. Female gender, positive urine culture, use of ureteral access sheath, and postoperative stenting were associated with residual fragments when treating ureteral stones. Adjusted surgeon-level SFRs varied for renal (26.1-72.4%; p < 0.001) and ureteral stones (52.2-90.2%; p < 0.001). Surgeon volume was not a predictor of being stone free for renal stones. Limitations include the lack of imaging in all patients and use of different imaging modalities. CONCLUSIONS: The real-world complete SFR after ureteroscopy is suboptimal with substantial surgeon-level variation. Interventions focused on surgical technique refinement are needed to improve outcomes for patients undergoing ureteroscopy and stone intervention. PATIENT SUMMARY: Results from a diverse group of community practicing and academic center urologists show that for a large number of patients, it is not possible to be completely stone free after ureteroscopy. There is substantial variation in surgeon outcomes. Quality improvement efforts are needed to address this.

Practice patterns and outcomes of urgent versus elective ureteroscopy in a statewide surgical collaborative.

PURPOSE: Urgent indications for nephrolithiasis treatment include obstruction with intractable pain or renal impairment without untreated infection. Patients and hospitals may benefit from urgent primary ureteroscopy. We aimed to examine variation in urgent ureteroscopy utilization and associated outcomes. METHODS: Using Reducing Operative Complications from Kidney Stones (ROCKS), we identified all ureteroscopy's between 2016 and 2019. Cases were classified by acuity (elective versus urgent). We assessed practice/urologist variation in urgent ureteroscopy performance. We characterized patients demographic, operative and outcomes data, making bivariate comparisons with elective ureteroscopy to understand implications of urgent surgery. We performed multilevel modeling to understand factors associated with unplanned healthcare encounters after urgent ureteroscopy. RESULTS: 12,859 cases were identified from 33 practices and 204 urologists, 10,854 (84.4%) elective and 2005 (15.6%) urgent. Urgent ureteroscopy was performed on younger patients (53 vs 57, p < 0.001), with higher rates of ureteral stones (72.8% vs 56.8%, p < 0.001). Urgent ureteroscopy rates varied widely by practice (2-70%) and urologist (0-98%). Urgent ureteroscopy had higher stenting rates (77.4% vs 72.5%, p < 0.001), stone free rates (66% vs 58.4%, p < 0.001), and postoperative ED visits (11% vs 7.2%, p < 0.001). There were no differences in intraoperative complications or unplanned hospitalizations. Factors predictive of ED visits in urgent ureteroscopy included concomitant ureteral/renal stone location (OR = 1.53, CI = 1.05-2.23, p = 0.035). CONCLUSIONS: In Michigan elective ureteroscopy is performed 5 times more frequently than urgent ureteroscopy with wide variation. Urgent ureteroscopy demonstrated low morbidity. Urgent ureteroscopy produced modestly higher stone free rates with a slightly increased frequency of unscheduled ED visits particularly for ureteral stones.

Development of a Surgical Decision Aid for Patients with Nephrolithiasis: Shockwave Lithotripsy vs Ureteroscopy.

Introduction and Objective: Shared decision making is recommended to guide medical/surgical treatment strategies. We aimed at developing a surgical decision aid (SDA) facilitating decision making between ureteroscopy (URS) or shockwave lithotripsy (SWL) in patients with symptomatic nephrolithiasis. Methods: The SDA scope was identified through discussions with patients and urologists in the Michigan Urological Surgery Improvement Collaborative (MUSIC). A steering committee of patient advocates, MUSIC coordinating center, content experts, biostatisticians, and urologists was formed. Content domains were assessed through best available evidence and content experts. For content validation we anonymously surveyed 35 MUSIC urologists. Content validity ratios (CVR), numeric value indicating degree of expert validity, were calculated. Face validation interviews were conducted with patient advocates. Results: The SDA prototype using descriptive plain language and pictorial information was designed for nephrolithiasis patients, candidates for SWL or URS. It first provides patients procedural education whereas the second section informs urologists of patient goals. Six content domains were chosen: anesthesia type, effectiveness, number of procedures, risk, pain, and recovery. Overall, 91.4% and 85.7% of MUSIC urologists indicated that each section accomplished their goals, respectively. Anesthesia received an unacceptable CVR. High levels of face validation overall were reported with unacceptable scoring for anesthesia and recovery. Conclusions: We developed an SDA facilitating treatment choice between SWL and URS with promising content and face validity. Agreement and contradiction between anesthesia type and recovery validation results indicate the importance of shared decision making and the need for a validated SDA. Future work should focus on the SDAs value and opportunities for refinement in practice.

Appropriateness Criteria for Ureteral Stent Omission following Ureteroscopy for Urinary Stone Disease.

Objective: To bridge the gap between evidence and clinical judgement, we defined scenarios appropriate for ureteral stent omission after uncomplicated ureteroscopy (URS) using the RAND/UCLA Appropriateness Method (RAM). We retrospectively assessed rates of appropriate stent omission, with the goal to implement these criteria in clinical practice. Methods: A panel of 15 urologists from the Michigan Urological Surgery Improvement Collaborative (MUSIC) met to define uncomplicated URS and the variables that influence stent omission decision-making. Over two rounds, they scored clinical scenarios for Appropriateness Criteria (AC) for stent omission based on a combination of variables. AC were defined by median scores: 1 to 3 (inappropriate), 4 to 6 (uncertain), and 7 to 9 (appropriate). Multivariable analysis determined the association of each variable with AC scores. Uncomplicated URS cases in the MUSIC registry were assigned AC scores and stenting rates assessed. Results: Seven variables affecting stent decision-making were identified. Of the 144 scenarios, 26 (18%) were appropriate, 88 (61%) inappropriate, and 30 (21%) uncertain for stent omission. Most scenarios appropriate for omission were pre-stented (81%). Scenarios with ureteral access sheath or stones >10mm were only appropriate if pre-stented. Stenting rates of 5,181 URS cases correlated with AC scores. Stents were placed in 61% of cases appropriate for omission (practice range, 25% to 98%). Conclusion: We defined objective variables and AC for stent omission following uncomplicated URS. AC scores correlated with stenting rates but there was substantial practice variation. Our findings demonstrate that the appropriate use of stent omission is underutilized.

Variation and Correlation in Postoperative Imaging After Shockwave Lithotripsy and Ureteroscopy by Treatment Modality: Results of a Statewide Clinical Registry.

OBJECTIVE: To understand how patient, practice/urologist-level factors impact imaging after ureteroscopy (URS) and shockwave lithotripsy (SWL). METHODS: Using the Reducing Operative Complications from Kidney Stones (ROCKS) clinical registry from the Michigan Urological Surgery Improvement Collaborative (MUSIC), we identified patients undergoing URS and SWL between 2016-2019. Frequency and modality of 60-day postoperative imaging was assessed. We made bivariate comparisons across demographic/clinical data and assessed provider/practice-level imaging rate variation. We assessed correlation between imaging use within practices by treatment modality. Multivariable logistic regression controlling for practice/urologist variation was used to adjust for group differences. RESULTS: 14,894 cases were identified (9621 URS, 5273 SWL) from 33 practices and 205 urologists. Overall postoperative imaging rate was 49.1% and was significantly different following URS and SWL (36.3% vs 72.4%, P<0.01). Substantial practice variation was seen in rates following URS (range 0-93.1%) and SWL (range 36-95.2%). Odds of postoperative imaging by practice varied significantly (range 0.02-1.96). Moderate postoperative imaging correlation for URS and SWL (0.7, P<0.001) was seen. No practice had significantly higher odds of post-URS imaging. There was increased odds of postoperative imaging for SWL modality, larger stones and renal stones. CONCLUSION: Imaging rates after URS are almost half the rate for SWL with wide variation, underscoring uncertainty with how postoperative imaging is approached. However, practices who have higher post-URS imaging rates also image highly after SWL. Increased patient complexity and renal stone location drive imaging following URS.

Opioid-Free Discharge is Not Associated With Increased Unplanned Healthcare Encounters After Ureteroscopy: Results From a Statewide Quality Improvement Collaborative.

OBJECTIVES: To evaluate patient factors associated with post-ureteroscopy opioid prescriptions, provider-level variation in opioid prescribing, and the relationship between opioid-free discharges and ED visits. METHODS: This is a retrospective analysis of a prospective cohort study of adults age 18 years and older who underwent primary ureteroscopy for urinary stones from June 2016 to September 2019 within the Michigan Urological Surgery Improvement Collaborative (MUSIC) Reducing Operative Complications from Kidney Stones (ROCKS) quality improvement initiative. Postoperative opioid prescription trends and variation among practices and surgeons were examined. Multivariable logistic regression models defined risk factors for receipt of opioid prescriptions. The association among opioid prescriptions and postoperative ED visits within 30 days of surgery was assessed among complete case and propensity matched cohorts, matched on all measured characteristics other than opioid receipt. RESULTS: 13,143 patients underwent ureteroscopy with 157 urologists across 28 practices. Post-ureteroscopy opioid prescriptions and ED visits declined (86% to 39%, P<.001; 10% to 6%, P<.001, respectively). Practice and surgeon-level opioid prescribing varied from 8% to 98%, and 0% to 98%, respectively. Patient-related factors associated with opioid receipt included male, younger age, and history of chronic pain. Procedure-related factors associated with opioid receipt included pre- and post-ureteroscopy ureteral stenting and access sheath use. An opioid-free discharge was not associated with increased odds of an ED visit (OR 0.77, 95% CI 0.62-0.95, P=.014). CONCLUSIONS: There was no increase in ED utilization among those not prescribed an opioid after ureteroscopy, suggesting their routine use may not be necessary in this setting.
