Background The objective of the current study was to characterize the association between travel distance/hospital volume relative to outcomes following resection of cholangiocarcinoma. Methods Patients were identified using the 2004–2015 National Cancer Database and stratified into quartiles according to travel distance/hospital volume. Multivariable regression models were utilized to examine the impact of travel distance and hospital volume on quality-of-care metrics and overall survival. Results Among 5125 patients, the majority of patients had T1/2 ( N  = 2006, 41.1%) and N0 disease ( N  = 2498, 50.9%). Median hospital quartile surgical volumes in cases/year were low volume (LV) 6, intermediate low volume (ILV) 7, intermediate high volume (IHV) 12, and high volume (HV) 24 cases/year. Median travel distance quartiles in miles were short travel (ST) 2.7, intermediate short travel (IST) 7.9, intermediate long travel (ILT) 18.9, and long travel (LT) 84.7. Longer travel distances were associated with better overall survival, as every 10 miles was associated with a 2% decrease in mortality ( p  = 0.02). Differences in quality-of-care metrics were largely mediated through travel distance. Conclusions Travel distance and hospital volume were associated with certain quality-of-care metrics among patients with cholangiocarcinoma. After controlling for hospital volume and travel distance simultaneously, only travel distance was associated with decreased risk of mortality.

ObjectiveEndoscopic mucosal resection (EMR) is established for the management of benign and early malignant upper GI disease. The aim of this observational study was to establish the effect of endoscopist procedural volume on mortality.DesignPatients undergoing upper GI EMR between 1997 and 2012 were identified from the Hospital Episode Statistics database. The primary outcome was 30-day mortality and secondary outcomes were 90-day mortality, requirement for emergency intervention and elective cancer re-intervention. Risk-adjusted cumulative sum (RA-CUSUM) analysis was used to assess patient mortality risk during initial stage of endoscopist proficiency gain and the effect of endoscopist and hospital volume. Mortality was compared before and after the change point or threshold in the RA-CUSUM curve.Results11 051 patients underwent upper GI EMR. Endoscopist procedure volume was an independent predictor of 30-day mortality. Fifty-eight per cent of EMR procedures were performed by endoscopists with annual volume of 2 cases or less, and had a higher 30-day and 90-day mortality rate for patients with cancer, 6.1% vs 0.4% (p<0.001) and 12% vs 2.1% (p<0.001), respectively. The requirement for emergency intervention after EMR for cancer was also greater with low volume endoscopists (1.8% vs 0.1%, p=0.002). In patients with cancer, the RA-CUSUM curve change points for 30-day mortality and elective re-intervention were 4 cases and 43 cases, respectively.ConclusionsEMR performed by high volume endoscopists is associated with reduced adverse outcomes. In order to reach proficiency, appropriate training and procedural volume accreditation training programmes are needed nationally.

BACKGROUND:Surgical site infection (SSI) rates are publicly reported as quality metrics and increasingly used to determine financial reimbursement. OBJECTIVE:To evaluate the volume-outcome relationship as well as the year-to-year stability of performance rankings following coronary artery bypass graft (CABG) surgery and hip arthroplasty. RESEARCH DESIGN:We performed a retrospective cohort study of Medicare beneficiaries who underwent CABG surgery or hip arthroplasty at US hospitals from 2005 to 2011, with outcomes analyzed through March 2012. Nationally validated claims-based surveillance methods were used to assess for SSI within 90 days of surgery. The relationship between procedure volume and SSI rate was assessed using logistic regression and generalized additive modeling. Year-to-year stability of SSI rates was evaluated using logistic regression to assess hospitals’ movement in and out of performance rankings linked to financial penalties. RESULTS:Case-mix adjusted SSI risk based on claims was highest in hospitals performing <50 CABG/year and <200 hip arthroplasty/year compared with hospitals performing ≥200 procedures/year. At that same time, hospitals in the worst quartile in a given year based on claims had a low probability of remaining in that quartile the following year. This probability increased with volume, and when using 2 years’ experience, but the highest probabilities were only 0.59 for CABG (95% confidence interval, 0.52–0.66) and 0.48 for hip arthroplasty (95% confidence interval, 0.42–0.55). CONCLUSIONS:Aggregate SSI risk is highest in hospitals with low annual procedure volumes, yet these hospitals are currently excluded from quality reporting. Even for higher volume hospitals, year-to-year random variation makes past experience an unreliable estimator of current performance.

Background The mainstay of treatment for pancreatic cancer is surgical resection; however, positive surgical margins remain commonplace. We identified hospitals with higher than predicted rates of positive margins and isolated factors that caused this discordance. Methods This is a retrospective review of patients with head of the pancreas adenocarcinoma in the National Cancer Database between 2004 and 2015. A nomogram was used to calculate the observed to expected positive margin rates (O/E) for facilities. If the O/E differed significantly (P < .05), it was considered an outlier. Results Among a total of 19 968 patients, 24.3% had positive margins. Among hospitals with lower than expected positive margin rates, 73.6% were academic or research programs, 17% were comprehensive community cancer programs, and none were community cancer programs (P = .0002). Within the group with higher than expected positive margin rates, 47% were comprehensive community cancer programs and 38.6% were academic or research programs (P = .0002). The mean hospital volume was higher in the low positive margin group (110.4 vs 48.8, P < .0001). Conclusions Facility type and hospital volume can predict improvement in the O/E ratio for margin positivity in pancreatic adenocarcinoma resection. Surgeons should consider referral to academic or research facilities with higher case volumes for improved surgical resection.

Background Neoadjuvant chemoradiation reduces local recurrence in locally advanced rectal cancer, and adherence to national and societal recommendations remains unknown. Objective To determine variability in guideline adherence in rectal cancer treatment and investigate whether hospital volume correlated with variability seen. Design We performed a retrospective analysis using the National Cancer Database rectal cancer participant user files from 2005 to 2010. Stage-specific predictors of neoadjuvant chemotherapy and radiation use were determined, and variation in use across hospitals analyzed. Hospitals were ranked based on likelihood of preoperative therapy use by stage, and observed-to-expected ratios for neoadjuvant therapy use calculated. Hospital outliers were identified, and their center characteristics compared. Results A total of 23,488 patients were identified at 1183 hospitals. There was substantial variability in the use of neoadjuvant chemoradiation across hospitals. Patients managed outside clinical guidelines for both stage 1 and stage 3 disease tended to receive treatment at lower-volume, community cancer centers. Conclusions There is substantial variability in adherence to national guidelines in the use of neoadjuvant chemoradiation for rectal cancer across all stages. Both hospital volume and center type are associated with over-treatment of early-stage tumors and under-treatment of more invasive tumors. These findings identify a clear need for national quality improvement efforts in the treatment of rectal cancer.

Background A strong relationship between hospital caseload and adverse outcomes has been demonstrated for pancreatic resections. Participation in regional surgical collaboratives may mitigate this phenomenon. This study sought to investigate changes over time in adverse outcomes after pancreatectomy across hospitals with different caseloads in a statewide surgical collaborative. Methods The study investigated patients undergoing pancreatic resection from January 2008 to August 2013 at Michigan Surgical Quality Collaborative (MSQC) hospitals (1007 patients in 19 academic and community hospitals). Risk-adjusted rates of major complications, mortality, and failure to rescue were compared between hospitals based on caseloads (low, medium, and high) in early (2008–2010) and later (2011–2013) periods. Finally, the degree to which different complications explained changes in hospital outcome variation was assessed. Results Adjusted rates of major complications and mortality decreased over time, driven largely by improvements at low-caseload hospitals. In 2008–2010, risk-adjusted major complication rates were higher for low-caseload than for high-caseload hospitals (27.8 vs. 17.8 %; p  = 0.02). However, these differences were attenuated in 2011–2013 (22.2 vs. 20.0 %; p  = 0.74). Similarly, adjusted mortality rates were higher in low-caseload hospitals in 2008–2010 (6.2 vs. 0.8 %; p  = 0.02), but these differences were attenuated in 2011–2013 (3.3 vs. 1.1 %; p  = 0.18). Variation in major complications decreased, largely due to decreased variation in “medical” complication rates, with less change in surgical-site complications. Conclusion Participation in regional quality collaboratives by lower-volume hospitals can attenuate the volume–outcome relationship for pancreatic surgery. Continued work in collaboratives with an emphasis on technical and intraoperative aspects of care may improve overall quality of care.

Background Little is known about between-hospital differences in the rate of suboptimal lymphadenectomy. This study characterizes variation in hospital-specific rates of suboptimal lymphadenectomy and its effect on overall survival in a national hospital-based registry. Methods Stage I–III colon cancer patients were identified from the 2003–2012 National Cancer Data Base. Bayesian multilevel logistic regression models were used to assess the impact of patient- and hospital-level factors on hospital-specific rates of suboptimal lymphadenectomy (<12 lymph nodes), and multilevel Cox models were used to estimate the effect of suboptimal lymphadenectomy at the patient (yes vs. no) and hospital level (quartiles of hospital-specific rates) on overall survival. Results A total of 360,846 patients across 1345 hospitals in the US met the inclusion criteria, of which 25 % had a suboptimal lymphadenectomy. Wide variation was observed in hospital-specific rates of suboptimal lymphadenectomy (range 0–82 %, median 44 %). Older age, male sex, comorbidity score, no insurance, positive margins, lower tumor grade, lower T and N stage, and sigmoid and left colectomy were associated with higher odds of suboptimal lymphadenectomy. Patients treated at lower-volume and non-academic hospitals had higher odds of suboptimal lymphadenectomy. Patient- and hospital-level factors explained 5 % of the between-hospital variability in suboptimal lymphadenectomy, leaving 95 % unexplained. Higher suboptimal lymphadenectomy rates were associated with worse survival (quartile 4 vs. quartile 1: hazard ratio 1.19, 95 % confidence interval 1.16–1.22). Conclusion Large differences in hospital-specific rates of suboptimal lymphadenectomy were observed, and this variation was associated with survival. Quality improvement initiatives targeting hospital-level adherence to the national standard may improve overall survival among resected colon cancer patients.

Background The use of inappropriate elective Percutaneous Coronary Intervention (PCI) has decreased over time, but hospital-level variation in the use of inappropriate PCI persists. Understanding the barriers and facilitators to the implementation of Appropriate Use Criteria (AUC) guidelines may inform efforts to improve elective PCI appropriateness. Methods All hospitals performing PCI in Washington State were categorized by their use of inappropriate elective PCI in 2010 to 2013. Semi-structured, qualitative telephone interviews were then conducted with 17 individual interviews at 13 sites in Washington State to identify barriers and facilitators to the implementation of the AUC guidelines. An inductive and deductive, team-based analytical approach, drawing primarily on Matrix analysis was performed to identify factors affecting implementation of the AUC. Results Specific facilitators were identified that supported successful implementation of the AUC. These included collaborative catheterization laboratory environments that allow all staff to participate with questions and opinions; ongoing AUC education with catheterization laboratory teams and referring providers; internal AUC peer review processes; interventional cardiologist be directly involved with the pre-procedural review process; checklist-based algorithms for pre-procedural documentation; systems redesign to include insurance companies; and AUC educational information with patients. Barriers to implementation of the AUC included external pressures, such as competition for patients, and the lack of shared medical records with sites that referred patients for coronary angiography. Conclusions The identified facilitators enabled sites to successfully implement the AUC. Catheterization laboratories struggling to successfully implement the AUC may consider utilizing these strategies to improve their processes to improve patient selection for elective PCI.

Background Pancreato-duodenectomy (PD) is a technically challenging operation with significant morbidity and mortality. Over the period of time, Tata Memorial Centre has evolved into a high-volume centre for management of pancreatic cancer. Aim of this study is to report the short- and long-term outcomes of 1200 consecutive PDs performed at single tertiary cancer centre in India. Methods 1200 PDs were performed from 1992 to 2017. Prospectively maintained database was used to retrospectively assess the short- and long-term outcomes. Results Study cohort was divided into periods A and B (500 and 700 patients, respectively). Both groups were comparable for demographic variables. Overall morbidity and mortality in entire cohort were 31.2% and 3.9%, respectively. Period B documented significant reduction in post-operative mortality (5.4% vs 2.8%), post-pancreatectomy haemorrhage (5.8% vs 3%) and bile leaks (3.4% vs 1.3%). However, incidence of delayed gastric emptying and clinically relevant post-operative pancreatic fistula was higher in period B. With median follow-up of 25 months, 3-year overall survival and disease-free survival for patients with pancreatic cancer were 43.7% and 38.7%, respectively, and that for periampullary tumours were 65.9% and 59.4%, respectively. Period B also corresponded with dissemination of technical expertise across diverse regions of India with specialised training of 35 surgeons. Conclusion Our study demonstrates the feasibility of delivering high-quality care in a dedicated high-volume centre even in a country with low incidence of pancreatic cancer with marked disparities in medical care and socio-economic conditions. Improved outcomes underscore the need to promote regionalisation via a dedicated training programme.
