Cancer Care Ontario Guidelines for radical prostatectomy: Striving for continuous quality improvement in community practice

Objective: Cancer Care Ontario has published an evidence-based guideline on their website “Guideline for Optimization of Surgicaland Pathological Quality Performance for Radical Prostatectomy in Prostate Cancer Management: Surgical and Pathological Guidelines.” The evidentiary base for this guideline was recently published in CUAJ. The CCO guideline proposes the following: a positive surgical margin (PSM) rate of <25% for organ-confined disease (pT2), a perioperative mortality of <1%, a rate of rectal injury <1%, and a blood transfusion rate <10% in non-anemic patients. The objective of this study was to review the radical prostatectomy practice at the Grey Bruce Health Services, an Ontario community hospital, and to compare our performance in relation to the Cancer Care Ontario guideline and the literature.Methods: We conducted a retrospective review of all radical prostatectomies performed at the Grey Bruce Health Services from January 1, 2006 to December 31, 2007. The following data were obtained from clinical records and pathology reports: patient age, pre-biopsy prostate-specific antigen, biopsy Gleason score, resected prostate gland weight, radical prostatectomy Gleason score, surgical margin status, pathological tumour stage (pT), lymph node dissection status, perioperative incidence of transfusion of blood products and if the patient was anemic (hemoglobin <140 g/L) preoperatively, incidence of rectal injury, and perioperative mortality within 30 days following surgery.Results: Using the method proposed by D’Amico, most patients undergoing radical prostatectomy were intermediate risk (62%), with a minority of low-risk (24%) and high-risk (14%) patients. The overall PSM rate was 37%. The rate of PSMs in organ-confined disease (pT2) was 26%. There was a statistically significant trend between increasing D’Amico risk category and increasing rate of PSM (Cochran-Armitage trend test, p = 0.023). There was a strong correlation between the pathological tumour stage and the rate of PSM (Cochran-Armitage trend test, p = 0.0003). The rate of blood transfusion in non-anemic patients was 6%. There was 1 patient (0.8%) who experienced a rectal injury. There were no perioperative deaths in our study group.Conclusion: Our results show that a community hospital group can appropriately select patients to undergo radical prostatectomy, as well as achieve an acceptable rate of PSMs. We believe that ongoing critical appraisal and reflective practice are essential to improving surgical outcomes and providing quality care.

Introduction: Robot-assisted radical prostatectomy (RARP) is a standard of care primary treatment for men with clinically localized prostate cancer (CLPC). The 2010 Canadian Urological Association (CUA) consensus guideline examining surgical quality performance for radical prostatectomy suggested benchmarks for surgical performance. To date, no study has examined whether Canadian surgeons are achieving these benchmarks. We determined the proportion of University of Alberta (UA) urologic surgeons achieving the CUA surgical quality performance outcome (SQPO) benchmarks. Methods: A retrospective quality assurance analysis of prospectively collected data from the PROstate Cancer Urosurgery Repository of Edmonton (PROCURE) was performed. Men who underwent RARP for CLPC between September 2007 and May 2018 by one of seven surgeons were analyzed. SQPO were an unadjusted pT2–R1 resection rate <25%, blood transfusion rate <10%, rectal injury rate <1%, and 90-day mortality rate <1%. Descriptive statistics were used to determine the proportion of surgeons achieving the benchmarks. Results: Data were evaluable for 2821 men. Seven of 7 (100%) surgeons achieved a blood transfusion rate <10%, rectal injury rate <1%, and 90-day mortality rate <1%. However, only six of seven surgeons achieved an unadjusted pT2–R1 resection rate <25%; one surgeon had an unadjusted pT2–R1 resection rate of 27.9%. Limitations include the lack of centralized pathology review for surgical margin status by a dedicated genitourinary pathologist. Conclusions: UA surgeons are achieving the CUA SQPO benchmarks for blood transfusion, rectal injury, and perioperative mortality. However, not all UA urologists are achieving a pT2– R1 resection rate <25%. Surgical quality performance initiatives designed to improve cancer control may be warranted.

AbstractTo evaluate potential factors associated with the risk of perioperative blood transfusion (PBT) with implications on length of hospital stay (LOHS) and major post-operative complications in patients who underwent robot-assisted radical prostatectomy (RARP) as a primary treatment for prostate cancer (PCa). In a period ranging from January 2013 to August 2019, 980 consecutive patients who underwent RARP were retrospectively evaluated. Clinical factors such as intraoperative blood loss were evaluated. The association of factors with the risk of PBT was investigated by statistical methods. Overall, PBT was necessary in 39 patients (4%) in whom four were intraoperatively. Positive surgical margins, operating time and intraoperative blood loss were associated with perioperative blood transfusion on univariate analysis. On multivariate analysis, the risk of PBT was predicted by intraoperative blood loss (odds ratio, OR 1.002; 95% CI 1.001–1.002; p < 0.0001), which was associated with prolonged operating time and elevated body mass index (BMI). PBT was associated with delayed LOHS and Clavien–Dindo complications > 2. In patients undergoing RARP as a primary treatment for PCa, the risk of PBT represented a rare event that was predicted by severe intraoperative bleeding, which was associated with increased BMI as well as with prolonged operating time. In patients who received a PBT, prolonged LOHS as well as an elevated risk of major Clavien–Dindo complications were seen.

Abstract The objective of this study was to identify trends in the percentage of type of respiratory viral vaccines administered to lots of beef calves offered for sale in summer video auctions from 2000 through 2018. There were 59,762 lots of single-gender beef calves (7,167,352 total calves) offered for sale in 145 summer video auctions during these years. Information describing calf lots was obtained from the auction service (Superior Livestock Auction, Fort Worth, TX) which included named vaccines administered to the lot. Named 4- or 5-way respiratory viral vaccines were classified into three groups based on the type of antigens they contained: all modified live antigens (MLV), all killed antigens (KILLED), and a combination of modified live and killed antigens (COMBO). The Cochran-Armitage Trend Test was used to quantify the significance of a trend in the usage of each respiratory viral vaccine type. There was an increase (P < 0.0001) in the percentage of MLV vaccines given to beef calf lots from 2000 (39.7%) through 2018 (88.9%). At the same time, the percentages of both KILLED and COMBO vaccines administered to lots of beef calves declined (P < 0.0001 and P < 0.0001, respectively). In 2000, 31.2% and 29.1% of the total respiratory viral vaccines given to beef calf lots were KILLED or COMBO vaccines, respectively. By 2018, only 4.7% of respiratory viral vaccines were KILLED, and only 6.4% were COMBO vaccines. This dramatic shift indicates an industry trend towards increasing MLV vaccine utilization compared with declining usage of KILLED and COMBO vaccines. This trend may be a result of MLV vaccine approval for use in calves nursing pregnant cows.

Surgeon Experience

AbstractThe positive surgical margin (PSM) and biochemical recurrence (BCR) are two main factors associated with poor oncotherapeutic outcomes after prostatectomy. This is an Asian population study based on a single-surgeon experience to deeply investigate the predictors for PSM and BCR. We retrospectively included 419 robot-assisted radical prostatectomy cases. The number of PSM cases was 126 (30.1%), stratified as 22 (12.2%) in stage T2 and 103 (43.6%) in stage T3. Preoperative prostate-specific antigen (PSA) > 10 ng/mL (p = 0.047; odds ratio [OR] 1.712), intraoperative blood loss > 200 mL (p = 0.006; OR 4.01), and postoperative pT3 stage (p < 0.001; OR 6.901) were three independent predictors for PSM while PSA > 10 ng/mL (p < 0.015; hazard ratio [HR] 1.8), pT3 stage (p = 0.012; HR 2.264), International Society of Urological Pathology (ISUP) grade > 3 (p = 0.02; HR 1.964), and PSM (p = 0.027; HR 1.725) were four significant predictors for BCR in multivariable analysis. PSMs occurred mostly in the posterolateral regions (73.8%) which were associated with nerve-sparing procedures (p = 0.012) while apical PSMs were correlated intraoperative bleeding (p < 0.001). A high ratio of pT3 stage after RARP in our Asian population-based might surpass the influence of PSM on BCR. PSM was less significant than PSA and ISUP grade for predicting PSA recurrence in pT3 disease. Among PSM cases, unifocal and multifocal positive margins had a similar ratio of the BCR rate (p = 0.172) but ISUP grade > 3 (p = 0.002; HR 2.689) was a significant BCR predictor. These results indicate that PSA and pathological status are key factors influencing PSM and BCR.

The Impact

ObjectiveTo determine trends and impact on outcomes of atrial fibrillation (AF) in patients with pre-existing psychosis.BackgroundWhile post-AF psychosis has been extensively studied, contemporary studies including temporal trends on the impact of pre-AF psychosis on AF and post-AF outcomes are largely lacking.MethodsWe used Nationwide Inpatient Sample (NIS) from the healthcare cost and utilization project (HCUP) from year's 2002–2012. We identified AF and psychosis as primary and secondary diagnosis respectively using validated international classification of diseases, 9th revision, and Clinical Modification (ICD-9-CM) codes, and used Cochrane–Armitage trend test and multivariate regression to generate adjusted odds ratios (aOR).ResultsWe analyzed total of 3.887.827AF hospital admissions from 2002–2012 of which 1.76% had psychosis. Proportion of hospitalizations with psychosis increased from 5.23% to 14.28% (P trend < 0.001). Utilization of atrial-cardioversion was lower in patients with psychosis (0.76%v vs. 5.79%, P < 0.001). In-hospital mortality was higher in patients with Psychosis (aOR 1.206; 95%CI 1.003–1.449; P < 0.001) and discharge to specialty care was significantly higher (aOR 4.173; 95%CI 3.934–4.427; P < 0.001). The median length of hospitalization (3.13 vs. 2.14 days; P < 0.001) and median cost of hospitalization (16.457 vs. 13.172; P < 0.001) was also higher in hospitalizations with psychosis.ConclusionsOur study displayed an increasing proportion of patients with Psychosis admitted due to AF with higher mortality and extremely higher morbidity post-AF, and significantly less utilization of atrial-cardioversion. There is a need to explore reasons behind this disparity to improve post-AF outcomes in this vulnerable population.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Mode Of Inheritance

The Cochran-Armitage trend test (CA) has become a standard procedure for association testing in large-scale genome-wide association studies (GWAS). However, when the disease model is unknown, there is no consensus on the most powerful test to be used between CA, allelic, and genotypic tests. In this article, we tackle the question of whether CA is best suited to single-locus scanning in GWAS and propose a power comparison of CA against allelic and genotypic tests. Our approach relies on the evaluation of the Taylor decompositions of non-centrality parameters, thus allowing an analytical comparison of the power functions of the tests. Compared to simulation-based comparison, our approach offers the advantage of simultaneously accounting for the multidimensionality of the set of features involved in power functions. Although power for CA depends on the sample size, the case-to-control ratio and the minor allelic frequency (MAF), our results first show that it is largely influenced by the mode of inheritance and a deviation from Hardy–Weinberg Equilibrium (HWE). Furthermore, when compared to other tests, CA is shown to be the most powerful test under a multiplicative disease model or when the single-nucleotide polymorphism largely deviates from HWE. In all other situations, CA lacks in power and differences can be substantial, especially for the recessive mode of inheritance. Finally, our results are illustrated by the comparison of the performances of the statistics in two genome scans.
