The Impact of a Statewide Active Surveillance Initiative: A Roadmap for Increasing Active Surveillance Utilization Nationwide

While patient-level factors influencing active surveillance (AS) use in Michigan are similar to those for the rest of the USA, implementation of a quality improvement initiative led to a drastic increase in AS utilization in Michigan compared to outside the state. Active surveillance (AS) is recommended as a management option for men with favorable-risk (low risk and favorable intermediate risk) prostate cancer; however, national rates remain low. The Michigan Urological Surgery Improvement Collaborative (MUSIC) established a quality improvement (QI) initiative in June 2014 to increase AS utilization. In this report, we analyze the rates of AS utilization over time in the state of Michigan (MUSIC) for men with favorable-risk prostate cancer and compare these to rates for other men diagnosed with favorable-risk prostate cancer in the USA outside the state of Michigan. While the variables that influence AS utilization were the same in both cohorts, we found that the AS utilization rates and the rate of increase were significantly higher in MUSIC. We conclude that the QI initiative started in MUSIC should serve as a roadmap to increasing AS use nationwide. Active surveillance (AS), which involves close monitoring with blood tests and scans, is recommended for management of favorable-risk prostate cancer to avoid or delay unnecessary treatment. Our results show that a quality improvement program in Michigan increased AS use for prostate cancer patients in the state. This program should be used to increase AS uptake throughout the USA

Partial nephrectomy should be classified as an inpatient procedure: Results from a statewide quality improvement collaborative

OBJECTIVES: To examine length of stay (LOS) and readmission rates for all minimally-invasive partial nephrectomy (MIPN) and MI radical nephrectomy (MIRN) performed for localized renal masses ≤7 cm in size (cT1RM) within 12 Michigan urology practices. Both RN and PN are commonly performed in treating cT1RM. Although technically more complex and associated with higher complication rates, Centers for Medicare & Medicaid Services considers MIPN an outpatient procedure and MIRN is inpatient. METHODS: We collected data for renal surgeries for cT1RM at MUSIC-KIDNEY practices between May 2017-February 2020. Data abstractors recorded clinical, radiographic, pathologic, surgical, and short-term follow-up data into the registry for cT1RM patients. RESULTS: Within MUSIC-KIDNEY, 807 patients underwent MI renal surgery at 12 practices. Median LOS for cT1RM patients after MIPN (n = 531, 66%) was 2 days and after MIRN (n = 276, 34%) was also 2 days. Among patients undergoing laparoscopic or robotic PN, 171 (32%), 230 (43%), and 130 (24%) stayed ≤1, 2, ≥3 days. Among patients undergoing laparoscopic or robotic RN, 81 (29%), 112 (41%), and 83 (30%) stayed ≤1, 2, ≥3 days. No significant difference was observed between MIPN and MIRN on LOS commensurate with outpatient surgery (≤1-day, OR = 0.97, P = 0.87). CONCLUSIONS: Less than one-third of patients had a LOS ≤1-day and LOS was comparable for MIPN and MIRN. Centers for Medicare & Medicaid Services should be advised that MIPN is a more complex surgery than MIRN, most patients receiving a MIPN will require a ≥2-day hospital stay and it would be more appropriate to classify MIPN an inpatient procedure with MIRN

Measuring to Improve: Peer and Crowd-sourced Assessments of Technical Skill with Robot-assisted Radical Prostatectomy.

UNLABELLED: Because surgical skill may be a key determinant of patient outcomes, there is growing interest in skill assessment. In the Michigan Urological Surgery Improvement Collaborative (MUSIC), we assessed whether peer and crowd-sourced (ie, layperson) video review of robot-assisted radical prostatectomy (RARP) could distinguish technical skill among practicing surgeons. A total of 76 video clips from 12 MUSIC surgeons consisted of one of four parts of RARP and underwent blinded review by MUSIC peer surgeons and prequalified crowd-sourced reviewers. Videos were rated for global skill (Global Evaluation Assessment of Robotic Skills) and procedure-specific skill (Robotic Anastomosis and Competency Evaluation). We fit linear mixed-effects models to estimate mean peer and crowd ratings for each video. Individual video ratings were aggregated to calculate surgeon skill scores. Peers (n=25) completed 351 video ratings over 15 d, whereas crowd-sourced reviewers (n=680) completed 2990 video ratings in 38 h. Surgeon global skill scores ranged from 15.8 to 21.7 (peer) and from 19.2 to 20.9 (crowd). Peer and crowd ratings demonstrated strong correlation for both global (r=0.78) and anastomosis (r=0.74) skills. The two groups consistently agreed on the rank order of lower scoring surgeons, suggesting a potential role for crowd-sourced methodology in the assessment of surgical performance. Lack of patient outcomes is a limitation and forms the basis of future study. PATIENT SUMMARY: We demonstrated the large-scale feasibility of assessing the technical skill of robotic surgeons and found that online crowd-sourced reviewers agreed with experts on the rank order of surgeons with the lowest technical skill scores

Evaluation of Patient- and Surgeon-Specific Variations in Patient-Reported Urinary Outcomes 3 Months After Radical Prostatectomy From a Statewide Improvement Collaborative

Importance: Understanding variation in patient-reported outcomes following radical prostatectomy may inform efforts to reduce morbidity after this procedure. Objective: To describe patient-reported urinary outcomes following radical prostatectomy in the diverse practice settings of a statewide quality improvement program and to explore whether surgeon-specific variations in observed outcomes persist after accounting for patient-level factors. Design, Setting, and Participants: This prospective population-based cohort study included 4582 men in the Michigan Urological Surgery Improvement Collaborative who underwent radical prostatectomy as primary management of localized prostate cancer between April 2014 and July 2018 and who agreed to complete validated questionnaires prior to surgery and at 3, 6, and 12 months after surgery. Data were analyzed from 2019 to June 2019. Exposures: Radical prostatectomy. Main Outcomes and Measures: Patient- and surgeon-level analyses of patient-reported urinary function 3 months after radical prostatectomy. Outcomes were measured using validated questionnaires with results standardized using previously published methods. Urinary function survey scores are reported on a scale from 0 to 100 with good function established as a score of 74 or higher. Results: For the 4582 men undergoing radical prostatectomy within the Michigan Urological Surgery Improvement Collaborative who agreed to complete surveys, mean (SD) age was 63.3 (7.1) years. Survey response rates varied: 3791 of 4582 (83%) responded at baseline, 3282 of 4137 (79%) at 3 months, 2975 of 3770 (79%) at 6 months, and 2213 of 2882 (77%) at 12 months. Mean (SD) urinary function scores were 88.5 (14.3) at baseline, 53.6 (27.5) at 3 months, 68.0 (25.1) at 6 months, and 73.7 (23.0) at 12 months. Regression analysis demonstrated that older age, lower baseline urinary function score, body mass index (calculated as weight in kilograms divided by height in meters squared) of 30 or higher, clinical stage T2 or higher, and lack of bilateral nerve-sparing surgery were associated with a lower probability of reporting good urinary function 3 months after surgery. When evaluating patients with good baseline function, the rate at which individual surgeons\u27 patients reported good urinary function 3 months after surgery varied broadly (0% to 54.5%; P \u3c .001). Patients receiving surgery from top-performing surgeons were more likely to report good 3-month function. This finding persisted after accounting for patient risk factors. Conclusions and Relevance: In this study, patient- and surgeon-level urinary outcomes following prostatectomy varied substantially. Documenting surgeon-specific variations after accounting for patient factors may facilitate identification of surgical factors associated with superior outcomes

Utilization of a Virtual Tumor Board for the Care of Patients With Renal Masses: Experience From a Quality Improvement Collaborative

INTRODUCTION: Multidisciplinary tumor board meetings are useful sources of insight and collaboration when establishing treatment approaches for oncologic cases. However, such meetings can be time intensive and inconvenient. We implemented a virtual tumor board within the Michigan Urological Surgery Improvement Collaborative to discuss and improve the management of complicated renal masses. METHODS: Urologists were invited to discuss decision-making for renal masses through voluntary engagement. Communication was performed exclusively through email. Case details were collected and responses were tabulated. All participants were surveyed about their perceptions of the virtual tumor board. RESULTS: Fifty renal mass cases were reviewed in a virtual tumor board that included 53 urologists. Patients ranged from 20-90 years old and 94% had localized renal mass. The cases generated 355 messages, ranging from 2-16 (median 7) per case; 144 responses (40.6%) were sent via smartphone. All urologists (100%) who submitted to the virtual tumor board had their questions answered. The virtual tumor board provided suggestions to those with no stated treatment plan in 42% of cases, confirmed the physician\u27s initial approach to their case in 36%, and offered alternative approaches in 16% of cases. Eighty-three percent of survey respondents felt the experience was Beneficial or Very Beneficial, and 93% stated increased confidence in their case management. CONCLUSIONS: Michigan Urological Surgery Improvement Collaborative\u27s initial experience with a virtual tumor board showed good engagement. The format reduced barriers to multi-institutional and multi-disciplinary discussions and improved the quality of care for selected patients with complex renal masses

Development and Validation of an Objective Scoring Tool for Robot-Assisted Radical Prostatectomy: Prostatectomy Assessment and Competency Evaluation.

PURPOSE: Comprehensive training and skill acquisition by urological surgeons are vital to optimize surgical outcomes and patient safety. We sought to develop and validate PACE (Prostatectomy Assessment and Competence Evaluation), an objective and procedure specific tool to assess the quality of robot-assisted radical prostatectomy. MATERIALS AND METHODS: Development and content validation of PACE was performed by deconstructing robot-assisted radical prostatectomy into 7 key domains utilizing the Delphi methodology. Reliability and construct validation were then assessed using de-identified videos performed by practicing surgeons and fellows. Consensus for each domain was defined as achieving a content validity index of 0.75 or greater. Reliability was assessed by the intraclass correlation and construct validation using a mixed linear model accounting for multiple ratings on the same video. RESULTS: After 3 rounds consensus was reached on wording, relevance of the skills assessed and concordance between the score assigned and the skill assessed. An intraclass correlation of 0.4 or greater was achieved for all domains. The expert group outperformed trainees in all domains but reached statistical significance in bladder drop (4.5 vs 3.4, p = 0.002), preparation of the prostate (4.4 vs 3.2, p \u3c0.0001), seminal vesicle and posterior plane dissection (8.3 vs 6.8, p = 0.03), and neurovascular bundle preservation (4.1 vs 2.4, p \u3c0.0001). Limitations included the lack of assessment of other key skills such as communication and decision making. CONCLUSIONS: PACE is a structured, procedure specific and reliable tool that objectively measures surgical performance during robot-assisted radical prostatectomy. It can differentiate different levels of expertise and provide structured feedback to customize training and surgical quality improvement

Noise injection for training artificial neural networks: A comparison with weight decay and early stopping

The purpose of this study was to investigate the effect of a noise injection method on the “overfitting” problem of artificial neural networks (ANNs) in two-class classification tasks. The authors compared ANNs trained with noise injection to ANNs trained with two other methods for avoiding overfitting: weight decay and early stopping. They also evaluated an automatic algorithm for selecting the magnitude of the noise injection. They performed simulation studies of an exclusive-or classification task with training datasets of 50, 100, and 200 cases (half normal and half abnormal) and an independent testing dataset of 2000 cases. They also compared the methods using a breast ultrasound dataset of 1126 cases. For simulated training datasets of 50 cases, the area under the receiver operating characteristic curve (AUC) was greater (by 0.03) when training with noise injection than when training without any regularization, and the improvement was greater than those from weight decay and early stopping (both of 0.02). For training datasets of 100 cases, noise injection and weight decay yielded similar increases in the AUC (0.02), whereas early stopping produced a smaller increase (0.01). For training datasets of 200 cases, the increases in the AUC were negligibly small for all methods (0.005). For the ultrasound dataset, noise injection had a greater average AUC than ANNs trained without regularization and a slightly greater average AUC than ANNs trained with weight decay. These results indicate that training ANNs with noise injection can reduce overfitting to a greater degree than early stopping and to a similar degree as weight decay

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

Introduction: To bridge the gap between evidence and clinical judgment, we defined scenarios appropriate for ureteral stent omission after uncomplicated ureteroscopy (URS) using the RAND/UCLA Appropriateness Method. 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 MUSIC (Michigan Urological Surgery Improvement Collaborative) met to define uncomplicated URS and the variables that influence stent omission decision making. Over 2 rounds, they scored clinical scenarios for appropriateness criteria (AC) for stent omission based on a combination of variables. AC were defined by median scores of 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 \u3e10 mm 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%). Conclusions: 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

A Configurational Perspective on Key Account Management

Most firms struggle with the challenge of managing their key customer accounts. There is a significant gap between the importance of this organizational design problem in practice and the research attention paid to it. Sound academic research on key account management (KAM) is very limited and fragmented. Drawing on research on KAM and team selling, the authors develop an integrative conceptualization of KAM and define key constructs in four areas: (1) Activities, (2) Actors, (3) Resources, (4) Approach Formalization. Adopting a configurational perspective to organizational research, the authors then use numerical taxonomy to empirically identify eight prototypical KAM approaches based on a cross-industry, cross-national study. The results show significant performance differences between the approaches. Overall, the paper builds a bridge between marketing organization research and relationship marketing research
