How Surgeons Think to Avoid Error: A Case Study of the Neurovascular Bundle Sparing During a Robotic Prostatectomy.

OBJECTIVE: To illustrate how experts efficiently navigate a "slowing down moment" to obtain optimal surgical outcomes using the neurovascular bundle sparing during a robotic prostatectomy as a case study. DESIGN: A series of semistructured interviews with four expert uro-oncologists were completed using a cognitive task analysis methodology. Cognitive task analysis, CTA, refers to the interview and extraction of a general body of knowledge. Each interview participant completed four 1 to 2-hour semistructured CTA interviews. The interview data were then deconstructed, coded, and analyzed using a grounded theory analysis to produce a CTA-grid for a robotic prostatectomy for each surgeon, with headings of: surgical steps, simplification maneuvers, visual cues, error/complication recognition, and error/complication management and avoidance. SETTING: The study took place at an academic teaching hospital located in an urban center in Canada. PARTICIPANTS: Four expert uro-oncologists participated in the study. RESULTS: Visual cues, landmarks, common pitfalls, and technique were identified as the 4 key components of the decision-making happening during a slowing down moment in the neurovascular bundle sparing during a robotic prostatectomy. CONCLUSION: The data obtained from the CTA is novel information identifying patterns and cues that expert surgeons use to inform their surgical decision-making and avoid errors. This decision-making knowledge of visual cues, landmarks, common pitfalls and techniques is also generalizable for other surgical subspecialties. Surgeon educators, surgical teaching programs and trainees looking to improve their decision-making skills could use these components to guide their educational strategies.

Venous thromboembolism risk in patients receiving neoadjuvant chemotherapy for bladder cancer.

INTRODUCTION: There is limited evidence to inform thromboprophylaxis use for patients receiving neoadjuvant chemotherapy prior to surgery in bladder cancer. We sought to determine the incidence of venous thromboembolism (VTE) in patients receiving neoadjuvant chemotherapy and cystectomy. We also assessed if the Khorana score was associated with VTE risk. METHODS: A retrospective cohort study was performed on consecutive patients who received a radical cystectomy for bladder cancer at The Ottawa Hospital between January 2016 and August 2020. Demographic information, chemotherapy data, operative characteristics, VTE and bleeding outcomes were collected from the start of treatment to 90 days postoperative. A Khorana score was calculated for each patient who received neoadjuvant chemotherapy. The primary outcome for this study was the incidence of VTE from the time the patient started treatment with neoadjuvant chemotherapy until 90 days post-cystectomy. Secondary outcomes included risk factors for VTE during neoadjuvant chemotherapy. RESULTS: Among 181 radical cystectomy cases during the study period, 123 had muscle-invasive disease and 72 (39.8%) received neoadjuvant chemotherapy. Eighteen (25.0%) patients who received neoadjuvant chemotherapy and radical cystectomy developed a VTE from the start of chemotherapy to 90 days postoperative. Thirteen of the 18 VTEs (72%) occurred while the patient was receiving chemotherapy. In multivariable analysis, the only factor associated with a significantly increased risk of VTE was treatment with neoadjuvant chemotherapy (Relative risk (RR) 3.05, 95% confidence interval [CI] 1.16-8.02; P = 0.02). A higher Khorana score was not associated with an increased risk of VTE in patients who received neoadjuvant chemotherapy (RR = 0.33, 95% CI 0.08-1.28, P = 0.11). One (1.4%) patient had a major bleeding event during neoadjuvant chemotherapy. CONCLUSIONS: Patients receiving neoadjuvant chemotherapy and radical cystectomy are at very high-risk of VTE. Prospective studies that assess the benefits and harms of pharmacologic thromboprophylaxis in this population are needed.

Do androgen-directed therapies improve outcomes in prostate cancer patients undergoing radical prostatectomy? A systematic review and meta-analysis.

INTRODUCTION: Approximately 50% of patients with non-metastatic prostate cancer are treated with radical prostatectomy (RP). While some men will be cured with surgery alone, a substantial proportion will experience cancer recurrence. Androgen-directed therapy (ADT) is an effective adjuvant therapy for patients treated with prostate radiation. Comparatively, the efficacy of ADT in surgical patients has not been well-studied. METHODS: A systematic search of MEDLINE, Embase, and the Cochrane Library from inception to July 2020 was performed. Randomized trials comparing ADT with RP vs. prostatectomy alone in patients with clinically localized prostate cancer were included. Neoadjuvant ADT and adjuvant ADT interventions were assessed separately. The primary outcomes were cancer recurrence-free survival (RFS) and overall survival (OS). Pathological outcomes following neoadjuvant ADT were also evaluated. RESULTS: Fifteen randomized trials met eligibility criteria; 11 evaluated neoadjuvant ADT (n=2322) and four evaluated adjuvant ADT (n=5205). Neoadjuvant ADT (three months of treatment) did not improve RFS (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.74-1.11) or OS (HR 1.22, 95% CI 0.62-2.41). Neoadjuvant ADT significantly decreased the risk of positive surgical margins (relative risk [RR] 0.48, 95% CI 0.41-0.56) and extraprostatic tumor extension (RR 0.75, 95% CI 0.64-0.89). Adjuvant ADT improved RFS (HR 0.65, 95% CI 0.45-0.93) but did not improve OS (HR 1.02, 95% CI 0.84-1.24). CONCLUSIONS: Neoadjuvant ADT causes a pathological downstaging of prostate tumors but has not been found to delay cancer recurrence nor extend survival. Few studies have evaluated adjuvant ADT. Trials are needed to determine the benefits and harms of intermediate- or long-term adjuvant ADT for RP patients.

Evaluation of individual and cumulative sites of extrarenal tumor invasion in pT3a clear cell renal cell carcinoma.

INTRODUCTION: The Tumor-Node-Metastasis classification of renal cell carcinoma (RCC) for pT3a tumors includes sinus fat invasion (SFI), perinephric fat invasion (PFI), renal vein invasion (RVI), and/or pelvicaliceal system invasion (PSI). The purpose of this study was to determine the association between these patterns of invasion (assessed individually and cumulatively) with the development of metastases and cancer-specific mortality (CSM). MATERIALS AND METHODS: We identified 160 patients who underwent radical nephrectomy for pT3a clear cell RCC between 2011 and 2017. The association between individual patterns of invasion and metastases and cancer-specific survival were evaluated with multivariate logistic regression. Cox Hazard proportion ratios and Kaplan-Meier survival curves were generated for patterns of invasion (assessed individually and cumulatively). RESULTS: The number of individual invasive patterns was as follows: 97/160 (61%) presented with RVI, 91/160 with SFI (57%), 62/160 with PFI (39%), and 24/160 (15%) with PSI. At multivariate analysis, both PFI and RVI were associated with metastases (P < 0.001 and 0.028, respectively). PFI (hazard ratio [HR] 4.12, 95% confidence interval [CI] 2.14-7.92; P < 0.001), RVI (HR 2.44, 95% CI 1.18-5.01; P = 0.015), SFI (HR 2.13, 95% CI 1.05-4.34; P = 0.036) had higher CSM, while PSI (HR 1.43, 95% CI 0.65-3.16; p = 0.38) did not show increased CSM. Furthermore, cumulative analysis showed that multiple invasive patterns resulted in worse CSM (p < 0.001). CONCLUSIONS: In our study, PFI was associated with the most aggressive behavior while PSI was the most indolent. Furthermore, the presence of more than one pattern of invasion was associated with worse CSM. These results indicate that reporting of the individual location and cumulative amount of pT3a patterns of invasion in clear cell RCC is clinically relevant.

Development and Implementation of a Continuing Medical Education Program in Canada: Knowledge Translation for Renal Cell Carcinoma (KT4RCC).

An in-person multidisciplinary continuing medical education (CME) program was designed to address previously identified knowledge gaps regarding quality indicators of care in kidney cancer. The objective of this study was to develop a CME program and determine if the program was effective for improving participant knowledge. CME programs for clinicians were delivered by local experts (uro-oncologist and medical oncologist) in four Canadian cities. Participants completed knowledge assessment tests pre-CME, immediately post-CME, and 3-month post-CME. Test questions were related to topics covered in the CME program including prognostic factors for advanced disease, surgery for advanced disease, indications for hereditary screening, systemic therapy, and management of small renal masses. Fifty-two participants attended the CME program and completed the pre- and immediate post-CME tests. Participants attended in Ottawa (14; 27%), Toronto (13; 25%), Québec City (18; 35%), and Montréal (7; 13%) and were staff urologists (21; 40%), staff medical oncologists (9; 17%), fellows (5; 10%), residents (16; 31%), and oncology nurses (1; 2%). The mean pre-CME test score was 61% and the mean post-CME test score was 70% (p = 0.003). Twenty-one participants (40%) completed the 3-month post-CME test. Of those that completed the post-test, scores remained 10% higher than the pre-test (p value 0.01). Variability in test scores was observed across sites and between French and English test versions. Urologists had the largest specialty-specific increase in knowledge at 13.8% (SD 24.2, p value 0.02). The kidney cancer CME program was moderately effective in improving provider knowledge regarding quality indicators of kidney cancer care. These findings support continued use of this CME program at other sites.

Female radical cystectomy patients have a higher risk of surgical site infections.

INTRODUCTION: Surgical site infections (SSI) are common after radical cystectomy. The objectives of this study were to evaluate if female sex is associated with postoperative SSI and if experiencing an SSI was associated with subsequent adverse events. METHODS: This was a historical cohort study of radical cystectomy patients from the American College of Surgeons' National Surgical Quality Improvement Program database between 2006 and 2016. The primary outcome was development of a SSI (superficial, deep, or organ/abdominal space) within 30 days of surgery. Multivariable logistic regression analyses were performed to determine the association between sex and other patient/procedural factors with SSI. Female patients with SSI were also compared to those without SSI to determine risk of subsequent adverse events. RESULTS: A total of 9,275 radical cystectomy patients met the inclusion criteria. SSI occurred in 1,277(13.7%) patients, 308 (16.4%) females and 969 (13.1%) males (odds ratio = 1.27; 95% confidence interval 1.10-1.47; P = 0.009). Infections were superficial in 150 (8.0%) females versus 410 (5.5%) males (P < 0.0001), deep in 40 (2.1%) females versus 114 (1.5%) males (P = 0.07), and organ/abdominal space in 118 (6.2%) females versus 445 (6.0%) males (P = 0.66). On multivariable analysis, female sex was independently associated with SSI (odds ratio = 1.21 confidence interval 1.01-1.43 P = 0.03). Females who experience SSI had higher probability of developing other complications including wound dehiscence, septic shock, and need for reoperation (all P < 0.05). CONCLUSIONS: Female sex is an independent risk factor for SSI following radical cystectomy. More detailed study of patient factors, pathogenic microbes, and treatment factors are needed to prescribe the best measures for infection prophylaxis.

Radiotherapy with radical cystectomy for bladder cancer: A systematic review and meta-analysis.

INTRODUCTION: Muscle-invasive bladder cancer (MIBC) is associated with high recurrence and mortality rates. The role of radiotherapy as an adjunct to radical cystectomy is not well-defined. We sought to evaluate the efficacy and safety of radiotherapy preoperatively or postoperatively for patients with MIBC receiving cystectomy compared to cystectomy alone. The primary outcome was overall survival. The secondary outcome was adverse effects. METHODS: MEDLINE, EMBASE, and CENTRAL were searched on August 30, 2016 for randomized controlled trials (RCTs) of patients undergoing cystectomy for bladder cancer. A control group receiving cystectomy alone and an intervention group with radiotherapy and cystectomy were required. The Jadad score was used to assess for bias. Fifteen studies representing 10 RCTs met eligibility criteria. RESULTS: A total of 996 patients were randomized in seven trials included in a meta-analysis of neoadjuvant radiotherapy. Insufficient data were available to complete a pooled analysis for adjuvant radiotherapy. There was a non-statistically significant improvement in overall survival for patients who received neo-adjuvant radiotherapy and cystectomy. At three years and five years, the odds ratios were 1.23 (95% confidence interval [CI] 0.72-2.09) and 1.26 (95% CI 0.76-2.09), respectively, in favour of neoadjuvant radiotherapy. Subgroup analyses including higher doses of radiotherapy showed greater effect on survival. CONCLUSIONS: These data suggest that radiotherapy prior to cystectomy may improve overall survival. This review was limited by old studies, heterogeneous patient populations, and radiotherapy treatment techniques that may not meet current standards. There is a need for current RCTs to further evaluate this effect.

Urinary function following radical cystectomy and orthotopic neobladder urinary reconstruction.

INTRODUCTION: An orthotopic neobladder urinary diversion aims to minimize the physical and psychological effects of radical cystectomy through avoidance of a stoma and maintenance of urethral voiding. Neobladder function reported in the literature ranges widely due to differences in patient selection and method of assessment. The objective of the study was to characterize functional outcomes of consecutive patients treated at a tertiary care hospital. METHODS: A historical cohort of patients who underwent radical cystectomy with a neobladder diversion performed at The Ottawa Hospital between January 2006 and December 2014 were reviewed. Outcomes of interest were urinary continence, use of clean intermittent catheterization (CIC), post-void residual volume, and uroflowmetry at three, six, and 12 months following cystectomy. RESULTS: During the study period, 158 neobladder diversions were performed. The mean age of patients was 63.1 years (standard deviation [SD] 8.1), and 81.7% were male. Significant daytime incontinence (>1 pad) three months following surgery was common (65%), but decreased to 8.6% by 12 months. Nighttime incontinence was also common at three months (54%) and improved at 12 months (20%). While no appreciable differences between men and women were observed for continence, more women performed CIC at 12 months post-surgery (59% of women; 9% of men; relative risk [RR] 0.15; 95% confidence interval [CI] 0.07-0.30). Among patients who did not catheterize, uroflowmetry and post-void residual volume parameters were stable between three and 12 months postoperative. CONCLUSIONS: Daytime and nighttime incontinence is common in neobladder patients following surgery, but improves considerably with time. Correspondingly, many female neobladder patients at our institution use CIC.

Long-term patient outcomes from the first year of a robotic surgery program using multi-surgeon implementation.

INTRODUCTION: There is concern that surgical quality initially declines during the learning phase of robotic surgery. At our institution, we used a multi-surgeon programmatic approach to the introduction of robotic surgery. The purpose of this study was to evaluate outcomes of patients treated during the first year of our program. METHODS: This is a historical cohort of all radical prostatectomy patients during a one-year period. Baseline, perioperative, and long-term followup data were prospectively and retrospectively collected. Treatment failure was a composite of any postoperative radiation, androgen-deprivation, or prostate-specific antigen (PSA) ≥0.2. RESULTS: During the study period, 225 radical prostatectomy procedures were performed (104 robotic and 121 open). Baseline characteristics were similar between groups (p>0.05). All patients were continent and 74% were potent prior to surgery. Mean estimated blood loss (280 cc vs. 760 cc; p<0.001) and blood transfusion (0% vs. 8.3%; p=0.002) was lower in the robotic cohort. Non-transfusion complications were similar between groups (13% vs. 12%; p=0.7). Mean hospital stay was shorter in the robotic cohort (1.4 vs. 2.5 days). There was no difference in overall positive margin rate (38% vs. 43%; p=0.4) or treatment failure at a median followup of 3.5 years (p=0.4). Robotically treated patients were more often continent (89% vs. 77%; p=0.02) and potent (48% vs. 32%; p=0.02). CONCLUSIONS: Using an inclusive multi-surgeon approach, robotic pros-tatectomy was introduced safely at a Canadian academic institution.

Evaluation of tumor morphologies and association with biochemical recurrence after radical prostatectomy in grade group 5 prostate cancer.

We assessed Gleason pattern 5 (GP5) and other prostatic adenocarcinoma (PCa) morphologies to determine their association with biochemical recurrence (BCR). A search for grade group 5 PCa with radical prostatectomy (RP) yielded 49 patients. RPs were reviewed for %GP5 and morphologies (sheets, single cells, cords, small solid cylinders, solid medium to large nests with rosette-like spaces [SMLNRS], comedonecrosis, cribriform glands, glomerulations, intraductal carcinoma of the prostate [IDC-P], and prostatic ductal adenocarcinoma [PDCa]). Prevalence of morphologies was as follows: single cells 100%, cribriform glands 98.7%, cords 85.7%, IDC-P 77.6%, comedonecrosis 53.1%, sheets 49.0%, small solid cylinders 49.0%, PDCa 44.9%, glomerulations 34.7%, and SMLNRS 14.3%. From 28 patients who were treated with RP as monotherapy, 64.3% (18/28) had BCR. Comedonecrosis, sheets, small solid cylinders, IDC-P, and PDCa were significantly associated with BCR. Number of morphologies on RP and %GP5 were higher in patients with BCR (6.8 ± 2.1 versus 3.7 ± 2.9%; P < 0.001 and 26.9 ± 16.8 versus 11.4 ± 14.1%; P = 0.02) with area under ROC curve of 0.89 (confidence intervals [CI] 0.77-1.00). Sensitivity/specificity was 77.8/80.0% for predicting BCR when ≥ 5 morphologies were present and 0.79 (CI 0.60-0.99) with sensitivity/specificity of 66.7/80.0% for predicting BCR when ≥ 15% GP5 was present. Hazard ratio for BCR was higher with increasing number of morphologies (1.23, CI 1.02-1.49; P = 0.034) but not %GP5 (0.99, CI 0.97-1.02, P = 0.622). Our results indicate that GP5 morphologies may represent a biologically heterogeneous group and that an increasing number of PCa morphologies on RP is strongly associated with an increased risk of BCR.

An assessment of Prostate Cancer Research International: Active Surveillance (PRIAS) criteria for active surveillance of clinically low-risk prostate cancer patients.

INTRODUCTION: Active surveillance is a strategy to delay or prevent treatment of indolent prostate cancer. The Prostate Cancer Research International: Active Surveillance (PRIAS) criteria were developed to select patients for prostate cancer active surveillance. The objective of this study was to compare pathological findings from PRIAS-eligible and PRIAS-ineligible clinically low-risk prostate cancer patients. METHODS: A D'Amico low-risk cohort of 1512 radical prostatectomy patients treated at The Ottawa Hospital or Memorial Sloan Kettering Cancer Centre between January 1995 and December 2007 was reviewed. Pathological outcomes (pT3 tumours, Gleason sum ≥7, lymph node metastases, or a composite) and clinical outcomes (prostate-specific antigen [PSA] recurrence, secondary cancer treatments, and death) were compared between PRIAS-eligible and PRIAS-ineligible cohorts. RESULTS: The PRIAS-eligible cohort (n=945) was less likely to have Gleason score ≥7 (odds ratio [OR] 0.61; 95% confidence interval [CI] 0.49-0.75), pT3 (OR 0.41; 95% CI 0.31-0.55), nodal metastases (OR 0.37; 95% CI 0.10-1.31), or any adverse feature (OR 0.56; 95% CI 0.45-0.69) compared to the PRIAS-ineligible cohort. The probability of any adverse pathology in the PRIAS-eligible cohort was 41% vs. 56% in the PRIAS-ineligible cohort. At median follow-up of 3.7 years, 72 (4.8%) patients had a PSA recurrence, 24 (1.6%) received pelvic radiation, and 13 (0.9%) received androgen deprivation. No difference was detected for recurrence-free and overall survival between groups (recurrence hazard ratio [HR] 0.71; 95% CI 0.46-1.09 and survival HR 0.72; 95% CI 0.36-1.47). CONCLUSIONS: Low-risk prostate cancer patients who met PRIAS eligibility criteria are less likely to have higher-risk cancer compared to those who did not meet at least one of these criteria.

Are renal tumour scoring systems better than clinical judgement at predicting partial nephrectomy complexity?

INTRODUCTION: We aimed to determine how renal tumour scoring systems, such as RENAL, PADUA, and Centrality (C)-index, compare to clinical judgement at predicting time required for tumour removal and kidney reconstruction during partial nephrectomy. METHODS: A consecutive cohort of partial nephrectomy patients treated at The Ottawa Hospital, a tertiary care uro-oncological centre, was retrospectively reviewed. Preoperative axial images were reviewed by four experienced urological oncologists who independently rated the complexity of a partial nephrectomy from 1-10 to generate a clinical judgement score. Two independent reviewers determined the RENAL, PADUA, and C-index scores. The time to complete tumour resection and renal reconstruction during partial nephrectomy was prospectively recorded. RESULTS: During the study period, 104 partial nephrectomies were performed. The mean partial nephrectomy complexity score based on clinical judgement was 3.4 (standard deviation [SD] 2.1) out of 10. There was good agreement between surgeons in assessing tumour complexity (intraclass correlation coefficient 0.72; 95% confidence interval [CI] 0.65, 0.78). The mean RENAL score was 6.7 (SD 1.6) out of a maximum of 12, the mean PADUA score was 8.5 (SD 1.5) out of a maximum of 14, and the mean C-index score was 3.8 (SD 2). Mean resection and reconstruction time was 24 minutes (SD 10 minutes). The correlation between clinical judgement score and time was 0.27 (p=0.005). The correlation between renal tumour scoring systems and time was 0.20 (p=0.04) for RENAL, 0.21 (p=0.03) for C-index, and 0.26 (p=0.007) for PADUA. RENAL and PADUA scores were significantly associated with surgical and total complications. CONCLUSIONS: The majority of variance in ischemia time is not explained by clinical judgement or renal tumour scoring systems. Renal tumour scoring systems were not better than the clinical judgement of urological oncologists at predicting ischemia time during partial nephrectomy.

A Multicentered, Propensity Matched Analysis Comparing Laparoscopic and Open Surgery for pT3a Renal Cell Carcinoma.

INTRODUCTION: To compare outcomes following laparoscopic renal surgery (LRS) and open renal surgery (ORS) in the treatment of pathologic T3a (pT3a) renal cell carcinoma (RCC) using a propensity matched analysis. MATERIALS AND METHODS: The Canadian Kidney Cancer Information System is a prospectively maintained database for patients diagnosed with RCC from 15 Canadian institutions. Patients treated for nonmetastatic pT3a RCC between 2008 and 2015 were included. Propensity score matching for age, gender, tumor size, grade, histology, and surgical approach was performed to compare laparoscopic radical and partial nephrectomy (LRN or LPN) with open radical or partial nephrectomy (ORN or OPN). The primary endpoint was recurrence-free survival (RFS). RESULTS: Two hundred twenty-six (45%) patients underwent LRS (88% LRN and 12% LPN), and 275 (55%) underwent ORS (75% ORN and 25% OPN). After a median follow-up of 21.1 months, 155 (72 LRS and 83 ORS) patients experienced recurrence. The 3-year RFS was 63% and 50% for the LRS and ORS groups, respectively, p = 0.36. On subgroup analysis, there was no significant difference in RFS among patients who underwent radical nephrectomy (3-year RFS 61% in LRN compared with 46% in ORN group, p = 0.32) or partial nephrectomy (77% in LPN compared with 79% in OPN group, p = 0.82). CONCLUSIONS: This study is the largest matched analysis comparing LRS and ORS for pT3a RCC. In matched patients, LRS showed no difference in oncologic outcomes compared with ORS and should be considered when technically feasible.

The Safety and Efficacy of Lysine Analogues in Cancer Patients: A Systematic Review and Meta-Analysis.

Lysine analogues are effective agents used for the reduction of blood loss and transfusion. However, the safety of lysine analogues in cancer patients remains in question due to a potential risk of venous thromboembolism (VTE). The objective of our review is to investigate safety and efficacy of lysine analogue administration in the patients with cancer. Medline, Embase, and The Cochrane Library were searched from inception to June, 2016. Reference lists of retrieved studies were searched to identify additional publications. We included randomized clinical trials in adult cancer patients for which a lysine analogue was administered for the purpose of blood loss reduction. Abstract and full-text selection as well as data extraction and risk of bias assessment was done by 2 independent reviewers. The primary outcome was venous thromboembolic events. Secondary outcomes were other adverse events, blood transfusion, and blood loss. Overall, 11studies involving 1177 patients evaluated at least one of the primary or secondary outcomes. Nine studies evaluated the effects of tranexamic acid, one study evaluated the effects of aminocaproic acid and one study examined both agents. No increased risk of venous thromboembolism was observed for patients who received lysine analogues compared to control (Peto OR 0.58; 95% CI 0.26-1.28). The administration of a lysine analogue significantly decreased both transfusion risk (pooled RR 0.52, 95% CI 0.34-0.80) and blood loss (SMD -1.57, 95% CI -2.21 to -0.92). Among 3 eligible studies, no increased risk was observed for mortality (Peto OR 1.01; 95% CI 0.14-7.18) or infection (OR 0.58; 95% CI 0.27-1.27). The safety of lysine analogues in cancer patients has not been extensively studied. Based on the available literature, lysine analogue use has not been associated with increased risk of venous thromboembolism or other adverse events, while being effective in reducing blood loss and subsequent transfusion.

Quality indicators in the management of bladder cancer: A modified Delphi study.

BACKGROUND: Survival in patients with bladder cancer has only moderately improved over the past 2 decades. A potential reason for this is nonadherence to clinical guidelines and best practice, leading to wide variations in care. Common quality indicators (QIs) are needed to quantify adherence to best practice and provide data for benchmarking and quality improvement. OBJECTIVE: To produce an evidence- and consensus-based list of QIs for the management of bladder cancer. METHODS: A modified Delphi method was used to develop the indicator list. Candidate indicators were extracted from the literature and rated by a 27-member Canadian expert panel in several rounds until consensus was reached on the final list of indicators. In rounds with numeric ratings, a frequency analysis was performed. RESULTS: A total of 86 indicators were rated, 52 extracted from the literature and 34 suggested by the panel. After iterative rounds of ratings and discussion, a final list of 60 QIs spanning several disciplines and phases of the cancer care continuum was developed. CONCLUSIONS: This is the first study to comprehensively produce common QIs representing structure, process, and outcome measures in bladder cancer management. Though developed in Canada, these indicators can be used in other countries with slight modifications to track performance and improve care.
