Abstract
PURPOSE OF REVIEW Lung cancer is the leading cause of cancer-related death in the United States. Pulmonary resection, in addition to perioperative systemic therapies, is a cornerstone of treatment for operable patients with early-stage and locoregional disease. In recent years, increased emphasis has been placed on surgical quality metrics: specific and evidence-based structural, process, and outcome measures that aim to decrease variation in lung cancer care and improve long term outcomes. These metrics can be divided into potential areas of intervention or improvement in the preoperative, intraoperative, and postoperative phases of care and form the basis of guidelines issued by organizations including the National Cancer Center Network (NCCN) and Society of Thoracic Surgeons (STS). This review focuses on established quality metrics associated with lung cancer surgery with an emphasis on the most recent research and guidelines. RECENT FINDINGS Over the past 18 months, quality metrics across the peri-operative care period were explored, including optimal invasive mediastinal staging preoperatively, the extent of intraoperative lymphadenectomy, surgical approaches related to minimally invasive resection, and enhanced recovery pathways that facilitate early discharge following pulmonary resection. SUMMARY Quality metrics in lung cancer surgery is an exciting and important area of research. Adherence to quality metrics has been shown to improve overall survival and guidelines supporting their use allows targeted quality improvement efforts at a local level to facilitate more consistent, less variable oncologic outcomes across centers.

JTCVS OPEN 2024; 18:221-231. [PMID: 38690419 PMCID: PMC11056476 DOI: 10.1016/j.xjon.2023.12.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 11/11/2023] [Accepted: 12/10/2023] [Indexed: 05/02/2024]
Abstract
Objectives Current National Comprehensive Cancer Network guidelines recommend definitive chemoradiation rather than surgery for patients with locally advanced clinical stage T3 and N2 (stage IIIB) lung cancer involving the chest wall. The data supporting this recommendation are controversial. We studied whether surgery confers a survival advantage over definitive chemoradiation in the National Cancer Database. Methods We identified all patients with clinical stage T3 and N2 lung cancer in the National Cancer Database from 2004 to 2017 who underwent a lobectomy with en bloc chest wall resection and compared them with patients with clinical stage T3 and N2 lung cancer who had definitive chemoradiation. We used propensity score matching to minimize confounding by indication while excluding patients with tumors in the upper lobes to exclude Pancoast tumors. We used 1:1 propensity score matching and Kaplan-Meir survival analyses to estimate associations. Results Of 4467 patients meeting all inclusion/exclusion criteria, 210 (4.49%) had an en bloc chest wall resection. Patients undergoing surgical resection were younger (mean age = 60.3 ± 10.3 years vs 67.5 ± 10.4 years; P < .001) and had more adenocarcinoma (59.0% vs 44.5%; P < .001) but were otherwise similar in terms of sex (37.1% female vs 42.0%; P = .167) and race (Whites 84.3% vs 84.0%; P = .276) compared with the definitive chemoradiation group. After resection, there was an unadjusted 30- and 90-day mortality rate of 3.3% and 9.5%, respectively. A substantial survival benefit with surgical resection persisted after propensity score matching (log-rank P < .001). Conclusions In this large observational study, we found that in select patients, en bloc chest wall resection for locally advanced clinical stage T3 and N2 lung cancer was associated with improved survival compared with definitive chemoradiation. National Comprehensive Cancer Network guidelines should be revisited.

Fragmented care, Commission on Cancer accreditation, and overall survival in patients receiving surgery and chemotherapy for esophageal cancer. Surgery 2024; 175:618-628. [PMID: 37743107 DOI: 10.1016/j.surg.2023.07.026] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 06/21/2023] [Accepted: 07/08/2023] [Indexed: 09/26/2023]
Abstract
BACKGROUND Increasing regionalization for esophagectomy for cancer may lead patients to travel for surgery at one institution and receive chemotherapy at another closer to home. We explore the effects on survival for care fragmentation, the Commission on Cancer status of secondary institutions providing chemotherapy, and the type of institution performing surgery. METHODS We queried the National Cancer Database to identify all patients who underwent esophagectomy for esophageal cancer and received perioperative chemotherapy between 2006 and 2019. Patients were divided into single-center care, fragmented-to-Commission on Cancer care, or fragmented-to-non-Commission on Cancer care. We identified associations using multivariable logistic regression, Kaplan-Meier survival analyses, and Cox proportional hazards models. RESULTS A total of 18,502 patients met the criteria for inclusion: 8,290 (44.8%) received single-center care; 3,414 (18.5%) fragmented-to-Commission on Cancer care; and 6,798 (36.4%) fragmented-to-non-Commission on Cancer care. Fragmented care was more likely in White patients (adjusted odds ratio = 1.25; P < .001) and in patients nonadjacent to a metropolitan area (adjusted odds ratio = 1.36; P < .001). Overall survival was equivalent between single-center and fragmented care, but undergoing an esophagectomy at an academic center was associated with improved survival (adjusted hazard ratio = 0.82; P = .016). In patients with an esophagectomy at a nonacademic center, overall survival was best if perioperative chemotherapy was administered at Commission on Cancer-accredited facilities compared with chemotherapy at fragmented-to-non-Commission on Cancer centers (P = .022). CONCLUSION Most of the esophageal cancer care in the US is fragmented at multiple institutions. When care is fragmented, it is most commonly at non-Commission on Cancer centers for perioperative chemotherapy. Overall survival is best when esophagectomy is performed at an academic center, and perioperative therapy is administered at Commission on Cancer-accredited facilities.

Decreasing prevalence of centers meeting the Society for Vascular Surgery abdominal aortic aneurysm guidelines in the United States. J Vasc Surg 2024; 79:240-249. [PMID: 37774990 DOI: 10.1016/j.jvs.2023.09.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 08/14/2023] [Accepted: 09/03/2023] [Indexed: 10/01/2023]
Abstract
OBJECTIVE Based on data supporting a volume-outcome relationship in elective aortic aneurysm repair, the Society of Vascular Surgery (SVS) guidelines recommend that endovascular aortic repair (EVAR) be localized to centers that perform ≥10 operations annually and have a perioperative mortality and conversion-to-open rate of ≤2% and that open aortic repair (OAR) be localized to centers that perform ≥10 open aortic operations annually and have a perioperative mortality ≤5%. However, the number and distribution of centers meeting the SVS criteria remains unclear. This study aimed to estimate the temporal trends and geographic distribution of Centers Meeting the SVS Aortic Guidelines (CMAG) in the United States. METHODS The SVS Vascular Quality Initiative was queried for all OAR, aortic bypasses, and EVAR from 2011 to 2019. Annual OAR and EVAR volume, 30-day elective operative mortality for OAR or EVAR, and EVAR conversion-to-open rate for all centers were calculated. The SVS guidelines for OAR and EVAR, individually and combined, were applied to each institution leading to a CMAG designation. The proportion of CMAGs by region (West, Midwest, South, and Northeast) were compared by year using a χ2 test. Temporal trends were estimated using a multivariable logistic regression for CMAG, adjusting by region. RESULTS Overall, 67,865 patients (49,264 EVAR; 11,010 OAR; 7591 aortic bypasses) at 336 institutions were examined. The proportion of EVAR CMAGs increased nationally by 1.7% annually from 51.6% (n = 33/64) in 2011 to 67.1% (n = 190/283) in 2019 (β = .05; 95% confidence interval [CI], 0.01-0.09; P = .02). The proportion of EVAR CMAGs across regions ranged from 27.3% to 66.7% in 2011 to 63.9% to 72.9% in 2019. In contrast, the proportion of OAR CMAGs has decreased nationally by 1.8% annually from 32.8% (n = 21/64) in 2011 to 16.3% (n = 46/283) in 2019 (β = -.14; 95% CI, -0.19 to -0.10; P < .01). Combined EVAR and OAR CMAGs were even less frequent and decreased by 1.5% annually from 26.6% (n = 17/64) in 2011 to 13.1% (n = 37/283) in 2019 (β = -.12; 95% CI, -0.17 to -0.07; P < .01). In 2019, there was no significant difference in regional variation of the proportion of combined EVAR and OAR CMAGs (P = .82). CONCLUSIONS Although an increasing proportion of institutions nationally meet the SVS guidelines for EVAR, a smaller proportion meet them for OAR, with a concerning downward trend. These data question whether we can safely offer OAR at most institutions, have important implications about sufficient OAR exposure for trainees, and support regionalization of OAR.

Abstract
BACKGROUND Studies have shown an association between surgical treatment volume and improved quality metrics. This study evaluated nationwide results in carotid artery stenting (CAS) procedural readmission rates, costs, and length of stay based on hospital treatment volume. METHODS We used the Nationwide Readmissions Database for carotid stenosis from 2010 to 2015. Patients receiving CAS were matched based on demographics, illness severity, and relevant comorbidities. Patients were matched 1:1 between low- and high-volume centers using a non-parametric preprocessing matching program to adjust for parametric causal inferences. Nearest-neighbor propensity score matching was performed using logit distance. RESULTS Low- and high-volume centers admitted a mean (SD) of 4.68 (3.79) and 25.10 (16.86) patients undergoing CAS per hospital, respectively. Comorbidities were significantly different and initially could not be adequately matched. Because of significant differences in baseline patient population characteristics after attempted matching between low- and high-volume centers, we used propensity adjustment with multivariate analysis. Using this alternative approach, no significant differences were observed between low- and high-volume centers for the presence of any complication, postoperative stroke, postoperative myocardial infarction, and readmission at 30 days. CONCLUSION In 1:1 nearest-neighbor matching with a high number of patients, our analysis did not result in well-matched cohorts for the effect of case volume on outcomes. Comparing analytical techniques for various outcomes highlights that outcome disparities may not be related to quality differences based on hospital size, but rather variability in patient populations between low- and high-volume institutions.

Abstract
Background: Robotic hiatal hernia (HH) repair has been demonstrated to be feasible and safe. Recent conflicting reports have emerged on the higher incidence of perioperative complications with robotic HH repair when compared with laparoscopic repair. Materials and Methods: A retrospective review of a prospective database at an academic medical center for all robotic HH repairs performed by a high-volume foregut surgeon from 2018 to 2021 was performed. Outcome measures included operative time, estimated blood loss (EBL), length of stay (LOS), conversion rate, need for esophageal lengthening procedure, intra- and perioperative complications, and 30-day in-hospital mortality. Results: One hundred four patients were included in the analysis. Fifteen percent of patients had a type I HH, 2% had a type II, 73% had a type III, and 10% had a type IV HH. Eighty-four percent of cases were primary and 16% were revisional. Fifty-four percent of patients had mesh placed and 4.4% had an esophageal lengthening procedure. Mean EBL was 15 mL and mean operative time was 151 minutes. Median LOS was 2 days (interquartile range 1-2 days). There were zero conversions. Intraoperative complication rate was 1% and 30-day complication rate was 4%. The 30-day in-hospital mortality was zero. Conclusion: In this retrospective analysis of 114 consecutive robotic HH repairs performed, with 83% type III or IV HHs and 16% revisional hiatal cases, our results demonstrate favorable perioperative outcomes, with lower EBL, shorter LOS, lower complication rate, zero conversions, and comparable operative times compared with historical laparoscopic data.

Abstract
PURPOSE Americans who reside in health professional shortage areas currently have less than half of the needed physician workforce. While the shortage designation has been associated with poor outcomes for chronic medical conditions, far less is known about outcomes after high-risk surgical procedures. METHODS We performed a retrospective review of Medicare beneficiaries living in health professional shortage areas and nonshortage areas who underwent abdominal aortic aneurysm repair, coronary artery bypass graft, esophagectomy, liver resection, pancreatectomy, or rectal resection between 2014 and 2018. Risk-adjusted multivariable logistic regression was used to determine whether rates of postoperative complications and 30-day mortality differed between patient cohorts. Beneficiary and hospital ZIP codes were used to quantify travel time to obtain care. FINDINGS Compared with patients living in nonshortage areas, patients living in health professional shortage areas traveled longer (median 60.0 vs 28.0 minutes, P<.001). There were no differences in risk-adjusted rates of complications (28.5% vs 28.6%, OR = 1.00, 95% CI 1.00-1.00, P = .59) and small differences in rates of 30-day mortality (4.2% vs 4.4%, OR = 0.95, 95% CI 0.95-0.95, P<.001) between beneficiaries living in shortage areas versus those not in shortage areas, respectively. CONCLUSIONS Patients living in health professional shortage area undergoing high-risk surgery traveled more than 2 times longer for their care to obtain similar outcomes. While reassuring for clinical outcomes, additional efforts may be needed to mitigate the travel burden experienced by shortage area patients.

Abstract
OBJECTIVE To examine the relationship between surgeon volume and operative morbidity and mortality for laryngectomy. DATA SOURCES The Nationwide Inpatient Sample was used to identify 45,156 patients who underwent laryngectomy procedures for laryngeal or hypopharyngeal cancer between 2001 and 2011. Hospital and surgeon laryngectomy volume were modeled as categorical variables. METHODS Relationships between hospital and surgeon volume and mortality, surgical complications, and acute medical complications were examined using multivariable regression. RESULTS Higher-volume surgeons were more likely to operate at large, teaching, nonprofit hospitals and were more likely to treat patients who were white, had private insurance, hypopharyngeal cancer, low comorbidity, admitted electively, and to perform partial laryngectomy, concurrent neck dissection, and flap reconstruction. Surgeons treating more than 5 cases per year were associated with lower odds of medical and surgical complications, with a greater reduction in the odds of complications with increasing surgical volume. Surgeons in the top volume quintile (>9 cases/year) were associated with a decreased odds of in-hospital mortality (OR = 0.09 [0.01-0.74]), postoperative surgical complications (OR = 0.58 [0.45-0.74]), and acute medical complications (OR = 0.49 [0.37-0.64]). Surgeon volume accounted for 95% of the effect of hospital volume on mortality and 16%-47% of the effect of hospital volume on postoperative morbidity. CONCLUSION There is a strong volume-outcome relationship for laryngectomy, with reduced mortality and morbidity associated with higher surgeon and higher hospital volumes. Observed associations between hospital volume and operative morbidity and mortality are mediated by surgeon volume, suggesting that surgeon volume is an important component of the favorable outcomes of high-volume hospital care.

BACKGROUND With a large body of literature demonstrating positive volume-outcome relationships for most major operations, minimum volume requirements have been suggested for concentration of cases to high-volume centers (HVCs). However, data are limited regarding disparities in access to these hospitals for pancreatectomy patients. METHODS The 2005-2018 National Inpatient Sample (NIS) was queried for all elective adult hospitalizations for pancreatectomy. Hospitals performing more than 20 annual cases were classified as HVCs. Mixed-multivariable regression models were developed to characterize the impact of demographic factors and case volume on outcomes of interest. RESULTS Of an estimated 127,527 hospitalizations, 79.8% occurred at HVCs. Patients at these centers were more frequently white (79.0 vs 70.8%; p < 0.001), privately insured (39.4 vs 34.2%; p < 0.001), and within the highest income quartile (30.5 vs 25.0%; p < 0.001). Adjusted analysis showed that operations performed at HVCs were associated with reduced odds of in-hospital mortality (adjusted odds ratio [AOR], 0.43; 95% confidence interval [CI], 0.34-0.55), increased odds of discharge to home (AOR, 1.17; 95% CI, 1.04-1.30), shorter hospital stay (β, -0.81 days; 95% CI, -1.2 to -0.40 days), but similar costs. Patients who were female (AOR, 0.88; 95% CI, 0.79-0.98), non-white (black: AOR, 0.66; 95% CI, 0.59-0.75; Hispanic: AOR, 0.56; 95% CI, 0.47-0.66; reference, white), insured by Medicaid (AOR, 0.63; 95% CI, 0.56-0.72; reference, private), and within the lowest income quartile (AOR, 0.73; 95% CI, 0.59-0.90; reference, highest) had decreased odds of treatment at an HVC. CONCLUSIONS For those undergoing pancreatectomies, HVCs realize superior clinical outcomes but treat lower proportions of female, non-white, and Medicaid populations. These findings may have implications for improving access to high-quality centers.

Abstract
BACKGROUND Multiple stakeholders have advocated for minimum volume standards for complex surgical procedures. The Leapfrog Group recommends that patients with non-small cell lung cancer (NSCLC) receive surgical resection at hospitals that perform at least 40 lung resections annually. However, the cost-effectiveness of this paradigm is unknown. METHODS A cost-effectiveness analysis was performed on 90-day and 5-year horizons for patients with clinical stage I NSCLC undergoing surgical resection at hospitals stratified by Leapfrog standard. Model inputs were derived from either the literature or a propensity score-matched cohort using the National Cancer Database. For the 5-year horizon, we simulated using a Markov model with 1-year cycle. Incremental cost-effectiveness ratio (ICER) was calculated to evaluate cost-effectiveness. RESULTS For the 90-day horizon, resection at a Leapfrog hospital was more costly ($25 567 vs $25 530) but had greater utility (0.185 vs 0.181 quality-adjusted life-years), resulting in an ICER of 10 506. Similarly, for the 5-year horizon, resection at a Leapfrog hospital was more costly ($26 600 vs $26 495) but more effective (3.216 vs 3.122 quality-adjusted life-years), resulting in an ICER of 1108. When the costs for long-distance travel, lodging, and loss of productivity for caregivers were factored in, the ICER was 20 499 during the 5-year horizon for resection at Leapfrog hospitals. Using a willingness-to-pay threshold of $50 000, resection at a Leapfrog hospital remained cost-effective. CONCLUSIONS Receiving surgery for clinical stage I NSCLC at hospitals that meet Leapfrog volume standards is cost-effective. Payers and policymakers should consider supporting patient and caregiver travel to higher volume institutions for lung cancer surgery.

Association of Textbook Outcome and Surgical Case Volume with Long-Term Survival in Patients Undergoing Surgical Resection for Pancreatic Cancer. J Am Coll Surg 2022; 235:829-837.

Abstract
BACKGROUND Current literature has identified textbook outcome (TO) as a quality metric after cancer surgery. We studied whether TO after pancreatic resection has a stronger association with long-term survival than individual hospital case volume. STUDY DESIGN Patients undergoing surgery for pancreatic adenocarcinoma from 2010 to 2015 were identified from the National Cancer Database. Hospitals were stratified by volume (low less than 6, medium 6 to 19, and high 20 cases or more per year), and overall survival data were abstracted. We defined TO as adequate lymph node count, negative margins, length of stay less than the 75th percentile, appropriate systemic therapy, timely systemic therapy, and without a mortality event or readmission within 30 days. The association of TO and case volume was assessed using a multivariable Cox regression model for survival. RESULTS Overall, 7270 patients underwent surgery, with 30.7%, 48.7%, and 20.6% performed at low-, medium-, and high-volume hospitals, respectively. Patients treated at low-volume hospitals were more likely to be Black, be uninsured or on Medicaid, have higher Charlson comorbidity scores, and be less likely to achieve TO (23.4% TO achievement vs 37.5% achievement at high-volume hospitals). However, high hospital volume was no longer associated with overall survival once TO was added to the multivariable model stratified by volume status. Achievement of TO corresponded to a 31% decrease in mortality (hazard ratio 0.69; p < 0.001), independent of hospital volume. CONCLUSIONS Improved long-term survival after pancreatic resection was associated with TO rather than high hospital volume. Quality improvement efforts focused on TO criteria have the potential to improve outcomes irrespective of case volume.

Abstract
BACKGROUND Centralization for complex cancer surgery may not always be feasible owing to socioeconomic disparities, geographic constraints, or patient preference. The present study investigates how the combined volume of complex cancer operations impacts postoperative outcomes at hospitals that are low-volume for a specific high-risk cancer operation. STUDY DESIGN Patients who underwent pneumonectomy, esophagectomy, gastrectomy, hepatectomy, pancreatectomy, or proctectomy were identified from the National Cancer Database (2004-2017). For every operation, 3 separate cohorts were created: low-volume hospitals (LVH) for both the individual cancer operation and the total number of those complex operations, mixed-volume hospital (MVH) with low volume for the individual cancer operation but high volume for total number of complex operations, and high-volume hospitals (HVH) for each specific operation. RESULTS LVH was significantly (all p ≤ 0.01) predictive for 30-day mortality compared with HVH across all operations: pneumonectomy (9.5% vs 7.9%), esophagectomy (5.6% vs 3.2%), gastrectomy (6.8% vs 3.6%), hepatectomy (5.9% vs 3.2%), pancreatectomy (4.7% vs 2.3%), and proctectomy (2.4% vs 1.3%). Patients who underwent surgery at MVH and HVH demonstrated similar 30-day mortality: esophagectomy (3.2 vs 3.2%; p = 0.993), gastrectomy (3.2% vs 3.6%; p = 0.637), hepatectomy (3.8% vs 3.2%; p = 0.233), pancreatectomy (2.8% vs 2.3%; p = 0.293), and proctectomy (1.2% vs 1.3%; p = 0.843). Patients who underwent pneumonectomy at MVH demonstrated lower 30-day mortality compared with HVH (5.4% vs 7.9%; p = 0.045). CONCLUSION Patients who underwent complex operations at MVH had similar postoperative outcomes to those at HVH. MVH provide a model for the centralization of complex cancer surgery for patients who do not receive their care at HVH.

Abstract
BACKGROUND Pancreatic cancer care is complex, and multiple disparities in receipt of therapies have been documented. The authors aimed to conduct a systematic review of the literature to critically assess and summarize disparities in access to oncologic therapies for pancreatic cancer. METHODS A search of PubMed, Scopus, Web of Science, and Cochrane databases were performed for studies reporting disparities in access to oncologic care for pancreatic cancer. Primary research articles published in the United States from 2000 to 2020 were included. Data were independently extracted, and risk of bias was assessed using the modified Newcastle-Ottawa scale. RESULTS The inclusion criteria were met by 47 studies. All the studies used retrospective data, with 70 % involving national database studies, 41 assessing the impact of race/ethnicity, 22 assessing the impact of socioeconomic status, 18 assessing the impact of insurance status, 23 assessing the impact of gender, 26 assessing the impact of age, and 3 assessing the impact of location on the delivery of cancer-directed therapies. Race, socioeconomic status, insurance status, gender, and age- based disparities in receipt of surgical resection, treatment at high-volume facilities and multimodal therapy for resectable pancreatic cancer, receipt of systemic chemotherapy for metastatic cancer, and receipt of expected standard-of-care treatment are reported. CONCLUSION Significant sociodemographic disparities in access to equitable oncologic care exist along the continuum of pancreatic cancer care. Multiple patient, provider, and systemic factors contribute to these disparities. The ongoing study of these disparities is important to elucidate processes that may be targeted to improve access to equitable oncologic care for patients with pancreatic cancer.

Abstract
BACKGROUND Racial disparities in outcomes have been shown to persist in many operative specialties, including the management of congenital heart disease. Using a demographic-adjusted methodology, we examined whether patient race influenced access to high-performing centers for the operative management of hypoplastic left heart syndrome. METHODS The 2005-2017 National Inpatient Sample was queried to identify all pediatric (≤5 years) hospitalizations with an operation for hypoplastic left heart syndrome. A racial disparity index was generated for each hospital and defined as the proportion of White patients receiving operative management for hypoplastic left heart syndrome divided by the proportion of White patients admitted for respiratory failure. This methodology quantified hospital-level racial variation while adjusting for the local racial makeup of each center. RESULTS Of the 17,275 patients who met inclusion criteria, 64.1% were managed at high-volume centers. Patients at high-volume centers had a similar distribution of operative type, age, and burden of comorbidities. The mean racial disparity index steadily grew from 1.06 at the lowest volume decile of operative volume to 1.51 at the highest, indicating an increasing proportion of White patients as volume increased. Using risk-adjusted analysis, each decile increase in hospital volume was associated with a 14% relative reduction in odds of mortality and a 0.06 increase in predicted racial disparity index. Increasing volume was further associated with reduced odds of non-home discharge but did not alter resource utilization. CONCLUSION We demonstrate that high-volume centers disproportionally serve White patients and have superior clinical outcomes compared to low-volume centers. This study highlights the critical importance of equitable access to expert care for high-risk conditions such as hypoplastic left heart syndrome.

Abstract
Introduction Patients who are disadvantaged socioeconomically or live in rural areas may not pursue surgery at high-volume centers where outcomes are better for some complex procedures. The objective of this study was to compare rural and urban patient differences directly by location of residence and outcomes after undergoing esophagectomy for cancer. Methods An analysis of the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) database was performed, capturing adult patients with esophageal cancer who underwent esophagectomy. Patients were stratified into rural or urban groups by the National Center for Health Statistics Urban-Rural Classification Scheme. Demographics, hospital variables, and outcomes were compared. Results A total of 2,877 patients undergoing esophagectomy for esophageal cancer were captured by the database, with 228 (7.92%) rural and 2,575 (89.50%) urban patients. The rural and urban groups had no differences in age, race, and insurance status, and shared many common comorbidities. Major outcomes of mortality (3.95% versus 4.27%, p = 0.815) and length of stay (15.75 ± 13.22 vs. 15.55 ± 14.91 days, p = 0.828) were similar for both rural and urban patients. There was a trend for rural patients to more likely be discharged home (35.96% vs. 29.79%, OR 0.667 [95% CI 0.479 – 0.929]; p = 0.0167). Conclusions This retrospective administrative database study indicated that rural and urban patients received equivalent postoperative care after undergoing esophagectomy. The findings were reassuring as there did not appear to be a disparity in major outcomes depending on the location of residence, but further studies are necessary to assure equitable treatment for rural patients.

Abstract
OBJECTIVE/HYPOTHESIS Utilization of flaps for reconstruction of large head and neck cancer (HNCA) defects has become more prevalent. The present study aimed to assess the impact of center experience as measured by annual hospital caseload on mortality, major complications, resource utilization, and 90-day readmissions following HNCA resection with flap reconstruction. STUDY DESIGN Non-Randomized Controlled Cohort Study. METHODS All adult patients undergoing elective HNCA resection with flap reconstruction were identified utilizing the 2010 to 2018 Nationwide Readmissions Database. Hospitals were subsequently classified as low-, medium-, or high-volume based on annual institutional surgical caseload tertiles. Multivariable regression models were implemented to assess the independent association of hospital volume with the outcomes of interest. RESULTS Over the nine-year study period, the proportion of HNCA resection with flap reconstruction gradually increased (12.8% in 2010 vs. 17.3% in 2018, P < .001). Although increasing hospital volume did not alter the odds of mortality, patients treated at high-volume centers were less likely to experience both surgical (adjusted odds ratio [AOR] 0.81, 95% confidence interval [CI] 0.67-0.97, P = .025) and medical complications (AOR 0.70, 95% CI 0.57-0.85, P < .001). Furthermore, these patients had shorter hospitalizations (-2.1 days, 95% CI -2.7 to -1.4 days, P < .001) and decreased costs (-$8,100, 95% CI -11,400 to -4,700, P < .001) compared to counterparts at low-volume centers. However, hospital volume did not impact 90-day readmissions. CONCLUSION Patients undergoing HNCA resection with flap reconstruction at high-volume centers were less likely to experience surgical and medical complications while incurring shorter hospitalizations and lower costs. Implementation of volume standards may be appropriate to improve outcomes in this surgical population. LEVEL OF EVIDENCE 3 Laryngoscope, 2021.

Abstract
BACKGROUND Socioeconomic- and demographic-based disparities exist in the treatment of pancreatic adenocarcinoma (PDAC). Medicaid expansion (ME) may have an impact on these disparities. Analyses of patients with PDAC from the National Cancer Database (NCDB) were performed to examine the impact of ME on access to treatment and outcomes. METHODS Patients with non-metastatic PDAC diagnosed between 2006 and 2016 were identified. Multiple logistic regression analyses were performed to evaluate factors associated with curative-intent surgical resection, multimodal therapy, treatment at a high-volume facility (HVF), and survival. RESULTS The study identified 41,876 patients who met the criteria. Medicaid expansion was independently associated with curative-intent resection (odds ratio [OR] 1.54; 95 % confidence interval [CI] 1.43-1.67; p < 0.001). In a multivariable analysis, ME was independently associated with multimodal therapy (OR 1.60; 95 % CI 1.44-1.76; p < 0.001) and treatment at an HVF (OR 1.57; 95 % CI 1.42-1.74; p < 0.001). Medicaid expansion was independently associated with improved 30-day mortality (OR 0.49; 95 % CI 0.34-0.79) and 90-day mortality (OR 0.48 95 % CI 0.35-0.59). Cox regression analysis demonstrated that after adjustment for other variables, ME status was associated with improved overall survival (hazard ratio [HR], 0.82; 95 % CI 0.73-0.90; p < 0.001). CONCLUSIONS Medicaid expansion is associated with increased use of care processes that improve outcomes in PDAC, operative outcomes, and overall survival. The study data suggest that ME has helped to improve disparities in PDAC in ME states.

The Association of Overall Annual Hospital Volume and Perioperative Outcomes following Free Flap Breast Reconstruction. Plast Reconstr Surg 2021; 147:196e-206e.

Abstract
BACKGROUND Hospital volume has been correlated with improved outcomes in oncologic care and complex surgical procedures. The authors sought to determine the relationship between overall annual hospital volume and perioperative outcomes following free flap breast reconstruction. METHODS Free flap breast reconstruction patients (n = 7991) were identified at 1907 centers using the Healthcare Cost and Utilization Project National Inpatient Sample database. Logistic regression characterized the association of hospital volume (total discharges per year) with systemic, surgical, and microsurgical complications. Patients were categorized as being treated at low- versus high-volume hospitals based on identified threshold volumes, and the association with the incidence of complications was estimated. RESULTS Initially, restricted cubic spline analysis suggested potential threshold volumes of 13,018 (95 percent CI, 7468 to 14,512) and 7091 (95 percent CI, 5396 to 9918) discharges per year, at which the risk for developing systemic and microsurgical complications may change, respectively. However, further patient-level evaluation of treatment at low- versus high-volume hospitals demonstrated that hospital volume did not predict the risk of developing perioperative systemic (OR, 1.28; 95 percent CI, 0.75 to 2.18; p = 0.36) or microsurgical complications (OR, 1.06; 95 percent CI, 0.78 to 1.44; p = 0.73). CONCLUSIONS Perioperative complications after free flap breast reconstruction did not differ between patients treated at low- versus high-volume hospitals after in-depth multiprong analysis. Patient outcomes are more likely associated with surgeon and programmatic experience. Overall annual hospital volume should not serve as a proxy for high-quality breast free flap care. .

Abstract
Purpose The delivery of surgical care in England has seen a momentum towards centralisation within larger volume hospitals and surgical teams. The aim of this study was to investigate outcomes in England in relationship to hospital and surgeon annual volumes for total thyroidectomy. Methods Data were extracted from the Hospital Episodes Statistics (HES) database for England. A 6-year period (April 2012–March 2018 inclusive) for all adult admissions for thyroidectomy was used in the analysis. The primary outcome measure used was a length of hospital stay greater than 2 days or an emergency readmission within 30 days following surgery. This was used as a proxy for surgical complications. A multilevel modelling strategy was used to adjust for hierarchy and potentially confounding. Results Data for 22,823 total thyroidectomies across 144 hospital trusts were used for analysis. For total thyroidectomy, larger volume surgeons had reduced levels of post-surgical complications; length of stay > 2 and > 4 days; emergency readmission at 30 days; and hypoparathyroidism, vocal cord palsy, stridor, and tracheostomy at 1-year post-surgery. Larger hospital volume was associated with lower levels of emergency readmission at 30 days and hypoparathyroidism at 1 year. Conclusions There is significant correlation between surgeon volume and clinical outcome for total thyroidectomy. The relationship was approximately linear, and a low-volume threshold could not be defined.

Abstract
PURPOSE Provider and hospital factors influence healthcare quality, but data are lacking to assess their impact on renal cancer surgery. We aimed to assess factors related to surgeon and hospital volume and study their impact on 30-day outcomes after radical nephrectomy. MATERIALS AND METHODS Renal surgery data were abstracted from Maryland's Health Service Cost Review Commission from 2000 to 2018. Patients ≤18 years old, without a diagnosis of renal cancer, and concurrently receiving another major surgery were excluded. Volume categories were derived from the mean annual cases distribution. Multivariable logistic and linear regression models assessed the association of volume on length of stay, intensive care days, cost, 30-day mortality, readmission, and complications. RESULTS 7,950 surgeries, completed by 573 surgeons at 48 hospitals, were included. Demographic, surgical, and admission characteristics differed between groups. Radical nephrectomies performed by low volume surgeons demonstrated increased post-operative complication frequency, mortality frequency, length of stay, and days spent in intensive care relative to other groups. However, after logistic regression adjusting for clinical risk and socioeconomic factors, only increased length of stay and ICU days remained associated with lower surgeon volume. Similarly, after adjusted logistic regression, hospital volume was not associated with the studied outcomes. CONCLUSIONS Surgeons and hospitals differ in regards to patient demographic and clinical factors. Barriers exist regarding access to high-volume care, and thus some volume-outcome trends may be driven predominantly by disparities and case mix.

Abstract
Studies over the past decade have clearly demonstrated an association between high surgeon and hospital volume and improved outcomes for women undergoing gynecologic surgical procedures. In contrast to procedures associated with higher morbidity, the association between higher volume and improved outcomes is often modest for gynecologic surgeries. The lower magnitude of this association has limited actionable policy changes for gynecologic surgery. These data have been driving initiatives such as regionalization of care, targeted quality improvement at low volume centers and volume-based credentialing in gynecology.

Abstract
To perform a systematic review of studies prospectively analyzing the impact of regionalization of complex surgical oncology care on patient outcomes. High volume care of complex surgical oncology patients has been repeatedly associated with improved outcomes. Most studies, however, are retrospective and have not prospectively accounted for confounders such as financial ability and social support. Four electronic databases (Ovid MEDLINE®, Ovid EMBASE, Cochrane Library (Wiley), and EBSCHOHost) were searched from inception until August 25, 2018. Two authors independently reviewed 5887 references, with a third independent reviewer acting as arbitrator when needed. Data extracted from 11 articles that met inclusion criteria. Risk of bias assessments conducted using MINORS criteria for the non-randomized, observational studies, and the Cochrane tool for the randomized-controlled trial. Of the 11 studies selected, we found 7 historically-controlled trials, two retrospective cohort studies with prospective data collection, one prospective study, and one randomized-controlled trial. 73% of studies were from Northern Europe, 18% from Ontario, Canada, and 9% from England. Pancreatic surgery accounted for 36% of studies, followed by gynecologic oncology (27%), thoracic surgery (18%), and dermatologic surgery (9%). The studies reported varying outcome parameters, but all showed improvement post-regionalization. Included studies featured poor-to-fair risk of bias. 11 studies indicated improved outcomes following regionalization of surgical oncology, but most exhibit poor methodological rigor. Prospective evidence for the regionalization of surgical oncology is lacking. More research addressing patient access to care and specialist availability is needed to understand the shortcomings of centralization.

Surgery 2021; 170:571-578. [PMID: 33775393 DOI: 10.1016/j.surg.2021.02.038] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 02/08/2021] [Accepted: 02/16/2021] [Indexed: 01/13/2023]
Abstract
BACKGROUND In an effort to improve perioperative and oncologic outcomes, there have been multiple quality improvement initiatives, including regionalization of high-risk procedures and hospital accreditation designations from independent organizations. These initiatives may, however, hinder access to high-quality surgical care for certain patients living in areas with high social vulnerability who may be disproportionally affected, leading to disparities in access and worse postoperative outcomes. METHODS Medicare beneficiaries who underwent liver or pancreas resection for cancer were identified using the 100% Medicare Inpatient Standard Analytic Files. Hospitals were designated as high-volume based on Leapfrog criteria. The Centers for Disease Control and Prevention's social vulnerability index database was used to abstract social vulnerability index information based on each beneficiary's county of residence at the time of operation. The probability that a patient received care at a high-volume hospital stratified by the social vulnerability of the patient's county of residence was examined. Risk-adjusted postoperative outcomes were compared across low, average, and high levels of vulnerability at both low- and high-volume hospitals. RESULTS Among 16,978 Medicare beneficiaries who underwent a pancreatectomy (n = 13,393, 78%) or a liver resection (n = 3,594, 21.2%) for cancer, the mean age was 73.3 years (standard deviation: 5.8), nearly half the cohort was female (n = 7,819, 46%), and the overwhelming majority were White (n = 15,034, 88.5%). Mean social vulnerability index was 49.8 (standard deviation 24.8) and mean Charlson comorbidity index was 4.8 (standard deviation: 3). Overall, 8,251 (48.6%) of patients had their operations at a high-volume hospital, and 3,802 patients had their operations at a hospital with Magnet recognition. Age and sex were similar within the low-, average-, and high-social vulnerability index cohorts (P > .05); however, race differed across social vulnerability index groups. White patients made up 93% (n = 3,241) of the low social vulnerability index compared with 83.9% (n = 2,706) of the high-social vulnerability index group, whereas non-Whites made up 7% (n = 244) of the low-social vulnerability index group compared with 16.1% (n = 556) of the high-social vulnerability index group (P < .001). The risk-adjusted overall probability of having surgery at a high-volume hospital decreased as social vulnerability increased (odds ratio: 0.98, 95% confidence interval: 0.97-0.99). Risk-adjusted probability of postoperative complications increased with social vulnerability index; however, among patients with high social vulnerability, risk of postoperative complications was lower at high-volume hospitals compared with low-volume hospitals. In contrast, there was no difference in postoperative complications between hospitals with and without Magnet recognition across social vulnerability index. CONCLUSION Patients residing in communities characterized by a high social vulnerability index were less likely to undergo high-risk cancer surgery at a high-volume hospital. Although postoperative complications and mortality increased as social vulnerability index increased, some of the risk appeared to be mitigated by having surgery at a high-volume hospital. These data highlight the importance of access to high-quality surgical care, especially among patients who may already be more vulnerable.

Editor's Choice - Optimal Threshold for the Volume-Outcome Relationship After Open AAA Repair in the Endovascular Era: Analysis of the International Consortium of Vascular Registries. Eur J Vasc Endovasc Surg 2021; 61:747-755.

Abstract
OBJECTIVE As open abdominal aortic aneurysm (AAA) repair (OAR) rates decline in the endovascular era, the endorsement of minimum volume thresholds for OAR is increasingly controversial, as this may affect credentialing and training. The purpose of this analysis was to identify an optimal centre volume threshold that is associated with the most significant mortality reduction after OAR, and to determine how this reflects contemporary practice. METHODS This was an observational study of OARs performed in 11 countries (2010 - 2016) within the International Consortium of Vascular Registry database (n = 178 302). The primary endpoint was post-operative in hospital mortality. Two different methodologies (area under the receiving operating curve optimisation and Markov chain Monte Carlo procedure) were used to determine the optimal centre volume threshold associated with the most significant mortality improvement. RESULTS In total, 154 912 (86.9%) intact and 23 390 (13.1%) ruptured AAAs were analysed. The majority (63.1%; n = 112 557) underwent endovascular repair (EVAR) (OAR 36.9%; n = 65 745). A significant inverse relationship between increasing centre volume and lower peri-operative mortality after intact and ruptured OAR was evident (p < .001) but not with EVAR. An annual centre volume of between 13 and 16 procedures per year was associated with the most significant mortality reduction after intact OAR (adjusted predicted mortality < 13 procedures/year 4.6% [95% confidence interval 4.0% - 5.2%] vs. ≥ 13 procedures/year 3.1% [95% CI 2.8% - 3.5%]). With the increasing adoption of EVAR, the mean number of OARs per centre (intact + ruptured) decreased significantly (2010 - 2013 = 35.7; 2014 - 2016 = 29.8; p < .001). Only 23% of centres (n = 240/1 065) met the ≥ 13 procedures/year volume threshold, with significant variation between nations (Germany 11%; Denmark 100%). CONCLUSION An annual centre volume of 13 - 16 OARs per year is the optimal threshold associated with the greatest mortality risk reduction after treatment of intact AAA. However, in the current endovascular era, achieving this threshold requires significant re-organisation of OAR practice delivery in many countries, and would affect provision of non-elective aortic services. Low volume centres continuing to offer OAR should aim to achieve mortality results equivalent to the high volume institution benchmark, using validated data from quality registries to track outcomes.

Abstract
OBJECTIVE Limited data exist exploring the relationship between multispecialty surgical collaboration and outcomes in general thoracic surgery. To address this, the Nationwide Inpatient Sample (NIS) was analyzed to determine whether the presence of an on-site cardiac surgery program is associated with improved general thoracic surgery outcomes. METHODS The NIS (1999-2008) was utilized to identify 389,959 patients who had a lobectomy, pneumonectomy, or esophagectomy. Short-term outcomes of patients undergoing these procedures were compared between hospitals with and without an on-site cardiac surgery program. Univariate and multivariate analyses were performed to determine patient and hospital predictors of mortality and morbidity. RESULTS During the study period, patients undergoing lobectomy (n = 314,130), pneumonectomy (n = 34,860), or esophagectomy (n = 40,969) were identified. Univariate analysis demonstrated lower mortality for lobectomy (P < 0.001) and esophagectomy (P < 0.001) but not pneumonectomy (P = 0.344) in hospitals with a cardiac surgery program. All-cause morbidity was significantly lower for all 3 procedures in hospitals with a cardiac surgery program. However, multivariate analysis demonstrated that a cardiac surgery program was not an independent predictor when adjusted for known confounders, particularly procedure volume and hospital academic teaching status. CONCLUSIONS The presence of an on-site cardiac surgery program is not in and of itself associated with improved general thoracic surgery outcomes. The presence of a cardiac surgery program is likely a surrogate for other known predictors of improved outcomes such as hospital teaching status and procedure volume.

Abstract
BACKGROUND Thoracic outlet syndrome (TOS) surgery is relatively rare and controversial, given the challenges in diagnosis as well as wide variation in symptomatic and functional recovery. Our aims were to measure trends in utilization of TOS surgery, complications, and mortality rates in a nationally representative cohort and compare higher versus lower volume centers. METHODS The National Inpatient Sample was queried using International Classification of Diseases, Ninth Revision, codes for rib resection and scalenectomy paired with axillo-subclavian aneurysm (arterial [aTOS]), subclavian deep vein thrombosis (venous [vTOS]), or brachial plexus lesions (neurogenic [nTOS]). Basic descriptive statistics, nonparametric tests for trend, and multivariable hierarchical regression models with random intercept for center were used to compare outcomes for TOS types, trends over time, and higher and lower volume hospitals, respectively. RESULTS There were 3,547 TOS operations (for an estimated 18,210 TOS operations nationally) performed between 2010 and 2015 (89.2% nTOS, 9.9% vTOS, and 0.9% aTOS) with annual case volume increasing significantly over time (P = 0.03). Higher volume centers (≥10 cases per year) represented 5.2% of hospitals and 37.0% of cases, and these centers achieved significantly lower overall major complication (defined as neurologic injury, arterial or venous injury, vascular graft complication, pneumothorax, hemorrhage/hematoma, or lymphatic leak) rates (adjusted odds ratio [OR] 0.71 [95% confidence interval 0.52-0.98]; P = 0.04], but no difference in neurologic complications such as brachial plexus injury (aOR 0.69 [0.20-2.43]; P = 0.56) or vascular injuries/graft complications (aOR 0.71 [0.0.33-1.54]; P = 0.39). Overall mortality was 0.6%, neurologic injury was rare (0.3%), and the proportion of patients experiencing complications decreased over time (P = 0.03). However, vTOS and aTOS had >2.5 times the odds of major complication compared with nTOS (OR 2.68 [1.88-3.82] and aOR 4.26 [1.78-10.17]; P < 0.001), and ∼10 times the odds of a vascular complication (aOR 10.37 [5.33-20.19] and aOR 12.93 [3.54-47.37]; P < 0.001], respectively. As the number of complications decreased, average hospital charges also significantly decreased over time (P < 0.001). Total hospital charges were on average higher when surgery was performed in lower volume centers (<10 cases per year) compared with higher volume centers (mean $65,634 [standard deviation 98,796] vs. $45,850 [59,285]; P < 0.001). CONCLUSIONS The annual number of TOS operations has increased in the United States from 2010 to 2015, whereas complications and average hospital charges have decreased. Mortality and neurologic injury remain rare. Higher volume centers delivered higher value care: less or similar operative morbidity with lower total hospital charges.

Widening volume and persistent outcome disparity in valve operations: New York statewide analysis, 2005-2016. J Thorac Cardiovasc Surg 2020; 164:1796-1803.e5. [PMID: 33431209 DOI: 10.1016/j.jtcvs.2020.11.098] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2020] [Revised: 10/28/2020] [Accepted: 11/04/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Volume concentration of complex noncardiac operations to high-volume centers has been observed, but whether this is also occurring in cardiac surgery is unknown. We examined the relationship between volume concentration and mortality rates for valve surgery and coronary artery bypass grafting (CABG) between 2005 and 2016 in New York State. METHODS We analyzed publicly available, hospital-level case volume and risk-adjusted mortality rates (RAMRs) from 2005 to 2016 for isolated CABG and isolated or concomitant valve operations performed in New York. We identified hospitals in the top- and bottom-volume quartiles for each procedure type and compared changes in percent market share and outcomes. Bivariate and univariate longitudinal analysis was used to evaluate the statistical significance of the temporal trend. RESULTS Among 36 centers, percent market share of the top-volume quartile increased for valve cases from 54.4% to 59.4%, whereas CABG share increased from 41.4% to 44.3%. No significant changes were noted in market share for the bottom quartile. The top-volume quartile demonstrated significant trends in improving outcomes over the study period for both valve procedures (RAMR: -0.261%/year, P < .001) and CABG (RAMR: -0.071%/year, P = .018). No significant trends were noted in the bottom quartile for either procedure. CONCLUSIONS In New York, over the last decade, highest-volume hospitals increased their market share for valve operations while maintaining lower mortality rates than lowest-volume hospitals. Valve volume is regionalizing in the setting of a persistent outcome gap between the highest- and lowest-volume hospitals, suggesting that volume-based referrals for specialized cardiac procedures may improve surgical mortality.

Abstract
Few reports have discussed appropriate strategies for patient referrals to advanced heart failure (HF) centers with available left ventricular assist devices (LVADs). We examined the association between the characteristics and prognoses of referred patients with advanced HF and the bed volume of the referring hospitals. This retrospective analysis evaluated 186 patients with advanced HF referred to our center for consultation about the indication of LVAD between January 1, 2015, and August 31, 2018. We divided the patients into two groups according to the bed volume of their referring hospital (high bed volume hospitals (HBHs): ≥ 500 beds in the hospital; low bed volume hospitals (LBHs): < 500 beds). We compared the primary outcome measure, a composite of LVAD implantation and all-cause death, between the patients referred from HBHs and patients referred from LBHs. The 186 patients with advanced HF referred to our hospital, who were referred from 130 hospitals (87 from LBHs and 99 from HBHs), had a mean age of 43.0 ± 12.6 years and a median left ventricular ejection fraction of 22% [15–33%]. The median follow-up duration of the patients was 583 days (119–965 days), and the primary outcome occurred during follow-up in 42 patients (43%) in the HBH group and 20 patients (23%) in the LBH group. Patients referred from HBHs tended to require catecholamine infusion on transfer more often than those referred from LBLs (36.5% (HBH), 20.2% (LBL), P = 0.021). Kaplan–Meier analysis indicates that the occurrence of the primary outcome was significantly higher in the HBH patients than in the LBH patients (log-rank P = 0.0022). Multivariate Cox proportional hazards analysis revealed that catecholamine support on transfer and long disease duration were statistically significant predictors of the primary outcome. Patients from HBHs had a greater risk of the primary outcome. However, the multivariate analysis did not indicate an association between referral from an HBH and the primary outcome. In contrast, catecholamine support on transfer, long duration of disease, and low blood pressure were independent predictors of the primary outcome. Therefore, these should be considered when determining the timing of a referral to an advanced HF center, irrespective of the bed volume of the referring hospital.

Abstract
BACKGROUND There has been a dramatic increase in worldwide health care spending over the last several decades. Operative procedures and perioperative care in the USA represent some of the most expensive episodes per patient. In view of both the rising cost of health care in general and the rising cost of surgical care specifically, policymakers and stakeholders have sought to identify ways to increase the value-improving quality of care while controlling (or diminishing) costs. In this context, we reviewed data relative to achieving the "value proposition" in the delivery of gastrointestinal surgical care. METHODS The National Library of Medicine online repository (PubMed) was text searched for human studies including "cost," "quality," "outcomes," "health care," "surgery," and "value." Results from this literature framed by the Donabedian conceptual model (identifying structures, processes, and outcomes), and the resulting impact of efforts to improve quality on costs. RESULTS The relationship between quality and costs was nuanced. Better quality care, though associated with better outcomes, was not always reported as concomitant with low costs. Moreover, some centers reported higher costs of surgical care commensurate with higher quality. Conversely, higher costs in health care delivery were not always linked to improved outcomes. While higher quality surgical care can lead to lower costs, higher costs of care were not necessarily associated with better outcomes. Strategies to improve quality, reduce cost, or achieve both simultaneously included regionalization of complex operations to high-volume centers of excellence, overall reduction in complications, introducing evidence-based improvements in perioperative care pathways including as enhanced recovery after surgery (ERAS), and elimination of inefficient or low-value care. CONCLUSIONS The relationship between quality and cost following gastrointestinal surgical procedure is complex. Data from the current study should serve to highlight the various means available to improve the value proposition related to surgery, as well as encourage surgeons to become more engaged in the national conversation around the Triple Aim of better health care quality, lower costs, and improved health care outcomes.

Abstract
BACKGROUND The lung allocation score (LAS) was designed to optimize the use of pulmonary allografts based on anticipated pretransplant survival and posttransplant outcome. Hospital admission status, not included in the LAS, has not been comprehensively investigated with regard to organ allocation. The objective of this study was to determine whether pretransplant hospital admission status was independently associated with posttransplant mortality and whether high center volume was associated with improved survival in that cohort. METHODS All consecutive adult lung transplants provided by the Scientific Registry of Transplant Recipients were retrospectively reviewed (from 2007 to 2017). Group stratification was performed based on admission status at the time of transplantation. A Cox proportional hazard regression was used to determine independent associations with posttransplant mortality. RESULTS During the study period, 3747 of 18,416 recipients (20%) were admitted to the hospital at the time of transplantation. Compared with nonadmitted recipients, LAS were significantly higher and waitlist times significantly shorter. Admitted recipients had higher rates of prolonged mechanical ventilation, higher rates of posttransplant dialysis, and longer posttransplant lengths of stay. Pretransplant admission to a low-volume center conferred significantly worse survival compared with nonadmitted patients, and high-volume centers were independently associated with improved survival compared with low-volume centers. CONCLUSIONS Hospital admission status is associated with increased posttransplant mortality independent of the LAS and the factors from which it is calculated. However, adjusted survival analysis demonstrates that admission to a high-volume center appears to be independently associated with improved survival compared with low-volume centers.

Abstract
OBJECTIVES To examine the effect of hospital volume on short and long-term outcomes for radical nephroureterectomy (RNUx). Upper tract urothelial carcinoma is a rare malignancy that few surgeons have experience with. The hospital volume-outcome relationship has been well established for other cancers but not RNUx. METHODS The National Cancer Database was queried for all cases of upper tract urothelial carcinoma that underwent RNUx from 2004 to 2016. Average annual hospital volume for radical nephroureterectomy was stratified into tertiles. The upper tertile, defined as 6 or more RNUx per year, was considered high volume while low volume was less than 6 RNUx per year. Kaplan-Meier and Cox proportional hazards regression were used to identify independent predictors of overall survival, and logistic regression was used to identify predictors of perioperative outcomes. RESULTS We identified 37,479 RNUx performed across 1290 hospitals. There were no differences in baseline health or cancer staging between patients who presented at low- versus high-volume centers. Both peri-operative survival (30- and 90-day mortality) and long-term overall survival were improved in patients treated at high-volume centers. On multivariable survival analysis, treatment at a high-volume center was associated with improved hazards of survival. This relationship for long-term survival remained consistent on landmark analysis where patients who died within 90 days of surgery were removed. CONCLUSIONS Treatment at a high-volume hospital was associated not only with improved short-term perioperative outcomes but also with improved overall long-term survival. The mechanism behind this is likely multifactorial with surgeon volume, and ancillary support services all playing critical roles.

Abstract
INTRODUCTION As high-risk cancer surgery continues to become more centralized, it is important to understand the association of neighborhood characteristics relative to access to surgical care. We sought to determine the neighborhood level characteristics that may be associated with travel patterns and utilization of high-volume hospitals. METHODS The California Office of Statewide Health Planning database was used to identify patients who underwent pancreatectomy (PD), esophagectomy (ES), proctectomy (PR), or pneumonectomy (PN) for cancer between 2014 and 2016. Total minutes (m) traveled as well as whether a patient bypassed the nearest hospital that performed the operation to get to a higher-volume center was assessed. Data were merged with the Centers for Disease control social vulnerability index (SVI). RESULTS Overall, 26,937 individuals (ES: 4.7%; PN: 53.5% PD: 13.9% PR: 27.9%) underwent a complex oncologic operation. Median travel time was 16 m (interquartile range [IQR] 8.3-30.24) [ES: 21.8 m (IQR 10.6-46.9); PN: 14 m (IQR 7.8-27.0); PD: 21.2 m (IQR 10.6-42.6); PR: 15 m (IQR 8.1-28.4)]. Nearly three-quarter of patients (ES: 34%; PN: 73%; PD: 72%; LR: 81%) underwent an operation at a high-volume hospital. For all four operations, patients who resided in a county with a high overall SVI were less likely to have surgery at a high-volume hospital (ES: odds ratio [OR] 0.39, 95% confidence interval [CI] 0.24-0.65; PN: OR: 0.67, 95% CI 0.51-0.88; PD: OR 0.61, 95% CI 0.44-0.84; PR: OR 0.76, 95% CI 0.58-0.98). CONCLUSIONS Patients residing in communities of high social vulnerability were less likely to undergo high-risk cancer surgery at a high-volume hospital. The identification of society-based contextual disparities in access to complex surgical care should serve to inform targeted strategies to direct additional resources toward these vulnerable communities.

Abstract
BACKGROUND Widespread adoption of endovascular aneurysm repair has led to a consequential decline in the use of open aneurysm repair (OAR). This evolution has had significant ramifications on vascular surgery training paradigms and contemporary practice patterns among established surgeons. Despite being the subject of previous analyses, the surgical volume-outcome relationship has remained a focus of controversy. At present, little is known about the complex interaction of case volume and surgeon experience with patient selection, procedural characteristics, and postoperative complications of OAR. The purpose of the present analysis was to examine the association between surgeon annual case volume and years of practice experience with OAR. METHODS All infrarenal OARs (n = 11,900; elective, 70%; nonelective, 30%) included in the Society for Vascular Surgery Vascular Quality Initiative from 2003 to 2019 were examined. Surgeon experience was defined as years in practice after training. The experience level at repair was categorized chronologically (≤5 years, n = 1667; 6-10 years, n = 1887; 11-15 years, n = 1806; ≥16 years, n = 6540). The annual case volume was determined by the number of OARs performed by the surgeon annually (median, five cases). Logistic regression was used to perform risk adjustment of the outcomes across surgeon experience and volume (five or fewer vs more than five cases annually) strata for in-hospital major complications and 30-day and 1-year mortality. RESULTS Practice experience had no association with unadjusted mortality (30-day death: elective, P = .2; nonelective, P = .3; 1-year death: elective, P = .2; nonelective, P = .2). However, more experienced surgeons had fewer complications after elective OAR (25% with ≥16 years vs 29% with ≤5 years; P = .004). A significant linear correlation was identified between increasing surgeon experience and performance of a greater proportion of elective OAR (P-trend < .0001). Risk adjustment (area under the curve, 0.776) revealed that low-volume (five or fewer cases annually) surgeons had inferior outcomes compared with high-volume surgeons across the experience strata for all presentations. In addition, high-volume, early career surgeons (≤5 years' experience) had outcomes similar to those of older, low-volume surgeons (P > .1 for all pairwise comparisons). Early career surgeons (≤5 years) had operated on a greater proportion of elective patients with American Society of Anesthesiologists class ≥4 (35% vs 30% [≥16 years' experience]; P = .0003) and larger abdominal aortic aneurysm diameters (mean, 62 vs 59 mm [≥16 years' experience]; P < .0001) compared with all other experience categories. Similarly, the use of a suprarenal cross-clamp occurred more frequently (26% vs 22% [≥16 years' experience]; P = .0009) but the total procedure time, estimated blood loss, and renal and/or visceral ischemia times were all greater for less experienced surgeons (P-trend < .0001). CONCLUSIONS Annual case volume appeared to be more significantly associated with OAR outcomes compared with the cumulative years of practice experience. To ensure optimal OAR outcomes, mentorship strategies for "on-boarding" early career, as well as established, low-volume, aortic aneurysm repair surgeons should be considered. These findings have potential implications for widespread initiatives surrounding regulatory oversight and credentialing paradigms.

Ann Thorac Surg 2020; 110:1832-1839. [PMID: 32622794 DOI: 10.1016/j.athoracsur.2020.05.069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 05/02/2020] [Accepted: 05/08/2020] [Indexed: 11/15/2022]
Abstract
BACKGROUND The aims of this study were to examine the factors associated with use of neoadjuvant chemoradiotherapy (NCR) for patients with locally advanced esophageal cancer and to evaluate the effect of NCR on survival. METHODS The 2004 to 2015 National Cancer Database was used to identify patients with cT1-4aN1-3M0 (stage II-IVA) esophageal adenocarcinoma who underwent esophagectomy. Patients were stratified by receipt of NCR. A multivariable logistic regression was performed to examine factors associated with NCR, and survival between the 2 groups was compared using a multivariable Cox model. RESULTS Of 8076 patients meeting the study criteria, 1616 (20%) did not receive NCR and 6460 (80%) did. In a multivariable regression, factors associated with receipt of NCR were a later year of diagnosis, treatment in a high-volume center, and clinical stage III disease. Factors associated with nonreceipt of NCR were increasing age, comorbidities, and treatment in a Middle Atlantic, South Central, or Pacific state. Receipt of trimodality therapy was associated with improved survival compared with other or no perioperative therapies (adjusted hazard ratio, 0.80; 95% confidence interval, 0.74-0.87). CONCLUSIONS Numerous personal-, demographic-, and treatment center-related factors account for variability in NCR for clinically node-positive esophageal adenocarcinoma, although neoadjuvant therapy was associated with a survival benefit. Further efforts are needed to identify reasons for these differences and design interventions to provide more equitable care for patients with esophageal cancer.

Abstract
CONTEXT There is a lack of accepted consensus on what should constitute appropriate quality-of-care indicators for bladder cancer. OBJECTIVE To evaluate the optimal management of bladder cancer and propose quality indicators (QIs). EVIDENCE ACQUISITION A systematic review was performed to identify literature on current optimal management and potential quality indicators for both non-muscle-invasive (NMIBC) and muscle-invasive (MIBC) bladder cancer. A panel of experts was convened to select a recommended list of QIs. EVIDENCE SYNTHESIS For NMIBC, preoperative QIs include tobacco cessation counselling and appropriate imaging before initial transurethral resection of bladder tumour (TURBT). Intraoperative QIs include administration of antibiotics, proper safe conduct of TURBT using a checklist, and performing restaging TURBT with biopsy of the prostatic urethra in appropriate cases. Postoperative QIs include appropriate receipt of perioperative adjuvant therapy, risk-stratified surveillance, and appropriate decision to change therapy when indicated (eg, bacillus Calmette-Guerin [BCG] unresponsive). For MIBC, preoperative QIs include multidisciplinary care, selection for candidates for continent urinary diversion, receipt of neoadjuvant cisplatin-based chemotherapy, time to commencing radical treatment, consideration of trimodal therapy as a bladder-sparing alternative in select patients, preoperative counselling with stoma marking, surgical volume of radical cystectomy, and enhanced recovery after surgery protocols. Intraoperative QIs include adequacy of lymphadenectomy, blood loss, and operative time. Postoperative QIs include prospective standardised monitoring of morbidity and mortality, negative surgical margins for pT2 disease, appropriate surveillance after primary treatment, and adjuvant cisplatin-based chemotherapy in appropriate cases. Participation in clinical trials was highlighted as an important component indicating high quality of care. CONCLUSIONS We propose a set of QIs for both NMIBC and MIBC based on established clinical guidelines and the available literature. Although there is currently a lack of level 1 evidence for the benefit of implementing these QIs, we believe that the measurement of these QIs could aid in the improvement and benchmarking of optimal care for bladder cancer. PATIENT SUMMARY After a systematic review of existing guidelines and literature, a panel of experts has recommended a set of quality indicators that can help providers and patients measure and strive towards optimal outcomes for bladder cancer care.

Fenestrated repair improves perioperative outcomes but lacks a hospital volume association for complex abdominal aortic aneurysms. J Vasc Surg 2020; 73:417-425.e1.

Abstract
BACKGROUND Complex abdominal aortic aneurysms (AAAs) have traditionally been treated with an open surgical repair (OSR). During the past decade, fenestrated endovascular aneurysm repair (FEVAR) has emerged as a viable option. Hospital procedural volume to outcome relationship for OSR of complex AAAs has been well established, but the impact of procedural volume on FEVAR outcomes remains undefined. This study investigated the outcomes of OSR and FEVAR for the treatment of complex AAAs and examined the hospital volume-outcome relationship for these procedures. METHODS A retrospective review of a statewide vascular surgery registry was queried for all patients between 2012 and 2018 who underwent elective repair of a juxtarenal/pararenal AAA with FEVAR or OSR. The primary outcomes were 30-day mortality, myocardial infarction, and new dialysis. Secondary end points included postoperative pneumonia, renal dysfunction (creatine concentration increase of >2 mg/dL from preoperative baseline), major bleeding, early procedural complications, length of stay, and need for reintervention. To evaluate procedural volume-outcomes relationship, hospitals were stratified into low- and high-volume aortic centers based on a FEVAR annual procedural volume. To account for baseline differences, we calculated propensity scores and employed inverse probability of treatment weighting in comparing outcomes between treatment groups. RESULTS A total of 589 patients underwent FEVAR (n = 186) or OSR (n = 403) for a complex AAA. After adjustment, OSR was associated with higher rates of 30-day mortality (10.7% vs 2.9%; P < .001) and need for dialysis (11.3% vs 1.8; P < .001). Postoperative pneumonia (6.8% vs 0.3%; P < .001) and need for transfusion (39.4% vs 10.4%; P < .001) were also significantly higher in the OSR cohort. The median length of stay for OSR and FEVAR was 9 days and 3 days, respectively. For those who underwent FEVAR, endoleaks were present in 12.1% of patients at 30 days and 6.1% of patients at 1 year, with the majority being type II. With a median follow-up period of 331 days (229-378 days), 1% of FEVAR patients required a secondary procedure, and there were no FEVAR conversions to an open aortic repair. Hospitals were divided into low- and high-volume aortic centers based on their annual FEVAR volume of complex AAAs. After adjustment, hospital FEVAR procedural volume was not associated with 30-day mortality or myocardial infarction. CONCLUSIONS FEVAR was associated with lower perioperative morbidity and mortality compared with OSR for the management of complex AAAs. Procedural FEVAR volume outcome analysis suggests limited differences in 30-day morbidity, although long-term durability warrants further research.

Abstract
Transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) are standard procedures for dealing with severe aortic stenosis patients. Researchers have not carried out a systematic review of the volume-outcome relationship in TAVR and SAVR. Our study is intended to address this problem. We systemically searched databases through MEDLINE, EMBASE, PUBMED, and the Cochrane Library up to September 2019. Two reviewers independently screened for the studies and evaluated bias. We used short-term mortality (in-hospital or 30-day mortality) as an outcome. A meta-analysis of TAVR with 115,596 patients ranging from 2005 to 2016 showed a result significantly in favor of high-volume hospitals (OR 0.43 (CI 0.36-0.51)). The subgroup of population period, region, data type, and cut-off value did not show any difference. A meta-analysis of SAVR comprising 418,384 patients ranging from 1994 to 2011 revealed that the OR of short-term mortality for a high-volume hospital compared with that of a low-volume hospital was 0.73 (CI 0.71, 0.74). No difference was observed in subgroups based on population period and cut-off. In conclusion, we found that short-term mortality was lower in high-volume hospitals for both TAVR and SAVR.

Abstract
OBJECTIVES To determine whether hospital and surgeon volume are associated with outcomes after operative fixation of tibial shaft fractures. METHODS Adults (≥18 year old) who underwent operative fixation of diaphyseal tibial fractures were identified in the New York Statewide Planning and Research Cooperative System data set from 2001 to 2015. Reoperation, nonunion, and other adverse event rates were compared across surgeon and hospital volume using multivariable Cox proportional hazards regression, adjusting for clinical and demographic factors. Low-volume providers (lowest 20%) were compared with high-volume providers (highest 20%). Low volume constituted <5 cases/year for hospitals and 1 case/year for surgeons. High volume constituted ≥40 cases/year for hospitals and ≥8 cases/year for surgeons. RESULTS Nine thousand one hundred forty-seven patients were included. Relative to high-volume surgeons, low-volume surgeons experienced slightly higher rates of pneumonia [2% vs. 1%, hazard ratio (HR) 2.50, 95% confidence interval (CI) 1.38-4.53, P = 0.003], and respiratory failure (5% vs. 3%, HR 1.88, 95% CI 1.30-2.71, P = 0.001). Compared with high-volume hospitals, low-volume hospitals experienced slightly lower rates of compartment syndrome (1% vs. 3%, HR 0.45, 95% CI 0.24-0.85, P = 0.01) and fasciotomies (3% vs. 7%, HR 0.57, 95% CI 0.38-0.85, P = 0.005). The rates of all other reoperations and adverse events compared among hospitals and surgeons were not significantly different. CONCLUSIONS We did not detect a clinically meaningful volume-outcome relationship for either surgeons or hospitals despite the use of a robust database with rigorous statistical methodology. Of note, these findings should not be applied to rare complex injuries such as those with extensive bone loss or articular extension, which are not well represented by this study population. Therefore, we conclude that typical tibial shaft fracture, including open or closed injuries, can be safely managed in the vast majority of orthopaedic settings and that this care does not necessarily require transfer to a specialty centers. Future research into orthopaedic volume-outcome relationships could be strengthened by the use of functional outcomes (which would likely require well-organized multicenter prospective registries). LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND Information on procedure volume of graduating chief residents (GCRs) for hepato-pancreato-biliary(HPB) surgical procedures may inform assessments of resident training. This study sought to characterize trends in operative volumes over a 19-year period to define the degree to which general surgery residents gain exposure to HPB procedures during training. METHODS The ACGME was queried for all HPB operations performed by GCR between 2000-2018. Total procedures as well as means and fold change was calculated and reported for each year. RESULTS Between 2000-2018, the number of general surgery residency programs varied between 240 and 254. A total of 411,383 HPB procedures (36.2% liver, 42.8% pancreas, 21% complex biliary) were performed by 22,229 GCR. Each year of the study, GCR had similar mean number total procedures:liver 7.4, pancreas 8.7, and complex biliary 4.4. For liver procedures there was no difference in the fold change over time, however for pancreas there was an increase in the fold change from 2.25 to 3.25. CONCLUSION Most GCRs are graduating with a low number of HPB procedures and trends suggesting a decrease in the mean number of procedures per GCR and an increasing variability among residents.

Abstract
BACKGROUND We aimed to examine whether safety-net burden is a significant predictor of failure-to-rescue (FTR) after major abdominal surgery controlling for patient and hospital characteristics, including surgical volume. METHODS Data were extracted from the 2007-2011 Nationwide Inpatient Sample. FTR was defined as mortality among patients experiencing major postoperative complications. Differences in rates of complications, mortality, and FTR across quartiles of safety-net burden were assessed with univariate analyses. Multilevel regression models were constructed to estimate the association between FTR and safety-net burden. RESULTS Among 238,645 patients, the incidence of perioperative complications, in-hospital mortality, and FTR were 33.7%, 4.4%, and 11.8%, respectively. All the outcomes significantly increased across the quartiles of safety-net burden. In the multilevel regression analyses, safety-net burden was a significant predictor of FTR after adjustment for patient and hospital characteristics, including hospital volume. CONCLUSION Increasing hospital safety-net burden is associated with higher odds of FTR for major abdominal surgery.

Abstract
INTRODUCTION Compared to low-volume hospitals, high-volume hospitals are associated with lower rates of perioperative morbidity and mortality. However, access to high-volume hospitals is unequal. We investigated racial and socioeconomic disparities among patients undergoing surgery for genitourinary malignancies at high-volume hospitals. MATERIAL AND METHODS We queried the National Cancer Database from 2004-2015 to identify patients who underwent radical prostatectomy, radical cystectomy, and nephrectomy for nonmetastatic prostate cancer, muscle-invasive urothelial bladder cancer, and kidney cancer, respectively. Hospitals were ranked based on their annual volume for the given procedure. The endpoint of our study was receipt of treatment at a high-volume hospital. Multivariable logistic regression models were used to identify predictors of treatment at a high-volume hospital. RESULTS Our final cohort consisted of 397,242 prostate cancer patients, 39,480 bladder cancer patients, and 292,095 kidney cancer patients. For prostate and bladder cancer, Black race was associated with lower odds of treatment at a high-volume hospital (Odds Ratio [OR] 0.83, 95% confidence interval [CI] 0.79-0.87 and 0.71, 95%CI 0.58-0.87; reference: White). Higher education level and private insurance status were associated with greater odds of treatment across all 3 procedures (strongest effect for prostate cancer; higher education level: OR 1.63 [1.58-1.68]; private insurance 1.86 [1.77-1.97]). Moreover, an interaction was found between race and study period for all cancers examined (P < 0.001). Subgroup analyses revealed that Black patients were more likely to undergo radical prostatectomy at high-volume hospitals in 2013-2015 (OR 0.98, 95%CI 0.94-1.02) compared to 2004-2006 (OR 0.83, 95%CI 0.79-0.87). CONCLUSION Across all procedures, patients with lower education status and lack of insurance were less likely to be treated at high-volume hospitals. For prostate cancer and bladder cancer, Black race was a negative predictor of treatment at high-volume hospitals. Further studies are needed to understand the root causes for this inequity.

Abstract
OBJECTIVE To examine the association between operator or hospital volume and procedural outcomes of carotid revascularization. BACKGROUND Operator and hospital volume have been proposed as determinants of outcome after carotid endarterectomy (CEA) or carotid artery stenting (CAS). The magnitude and clinical relevance of this relationship are debated. METHODS We systematically searched PubMed and EMBASE until August 21, 2017. The primary outcome was procedural (30 days, in-hospital, or perioperative) death or stroke. Obtained or estimated risk estimates were pooled with a generic inverse variance random-effects model. RESULTS We included 87 studies. A decreased risk of death or stroke following CEA was found for high compared to low operator volume with a pooled adjusted odds ratio (OR) of 0.50 (95% confidence interval [CI] 0.28-0.87; 3 cohorts), and a pooled unadjusted relative risk (RR) of 0.59 (95% CI 0.42-0.83; 9 cohorts); for high compared to low hospital volume with a pooled adjusted OR of 0.62 (95% CI 0.42-0.90; 5 cohorts), and a pooled unadjusted RR of 0.68 (95% CI 0.51-0.92; 9 cohorts). A decreased risk of death or stroke after CAS was found for high compared to low operator volume with an adjusted OR of 0.43 (95% CI 0.20-0.95; 1 cohort), and an unadjusted RR of 0.50 (95% CI 0.32-0.79; 1 cohort); for high compared to low hospital volume with an adjusted OR of 0.46 (95% CI 0.26-0.80; 1 cohort), and no significant decreased risk in a pooled unadjusted RR of 0.72 (95% CI 0.49-1.06; 2 cohorts). CONCLUSIONS We found a decreased risk of procedural death and stroke after CEA and CAS for high operator and high hospital volume, indicating that aiming for a high volume may help to reduce procedural complications. REGISTRATION This systematic review has been registered in the international prospective registry of systematic reviews (PROSPERO): CRD42017051491.
