ABSTRACT
OBJECTIVE: Through a systematic review and spline curve analysis, to better define the minimum volume threshold for hospitals to perform (pancreaticoduodenectomy) and the high-volume center. BACKGROUND: The pancreaticoduodenectomy (PD) is a resource-intensive procedure, with high morbidity and long hospital stays resulting in centralization towards high-volume hospitals; the published definition of high volume remains variable. MATERIALS AND METHODS: Following a systematic review of studies comparing PD outcomes across volume groups, semiparametric regression modeling of morbidity (%), mortality (%), length of stay (days), lymph node harvest (number of nodes), and cost ($USD) as continuous variables were performed and fitted as a smoothed function of splines. If this showed a nonlinear association, then a "zero-crossing" technique was used, which produced "first and second derivatives" to identify volume thresholds. RESULTS: Our analysis of 33 cohort studies (198,377 patients) showed 55 PDs/year and 43 PDs/year were the threshold value required to achieve the lowest morbidity and highest lymph node harvest, with model estimated df 5.154 ( P <0.001) and 8.254 ( P <0.001), respectively. The threshold value for mortality was ~45 PDs/year (model 9.219 ( P <0.001)), with the lowest mortality value (the optimum value) at ~70 PDs/year (ie, a high-volume center). No significant association was observed for cost ( edf =2, P =0.989) and length of stay ( edf =2.04, P =0.099). CONCLUSIONS: There is a significant benefit from the centralization of PD, with 55 PDs/year and 43 PDs/year as the threshold value required to achieve the lowest morbidity and highest lymph node harvest, respectively. To achieve mortality benefit, the minimum procedure threshold is 45 PDs/year, with the lowest and optimum mortality value (ie, a high-volume center) at approximately 70 PDs/year.

PURPOSE: This study compared the quality of healthcare before and after implementation of a policy restructuring the healthcare delivery system and estimated the impact of centralization. METHODS: We used the National Clinical Database to study patients undergoing esophagectomies from 2011 to 2016. We compared the effect of centralization based on the patient background, surgical mortality, and year of surgery. Difference-in-difference methods based on the generalized estimating equation logistic regression model were used for before-and-after comparisons after adjusting for patient-level expected surgical mortality. RESULTS: In total, 34,640 cases were identified. More cases with risk factors were noted in ultra-low-volume hospitals, where 38.4% of cases in underpopulated areas were treated, than in higher volume facilities, and the operative mortality, readmission within 30 days and length of stay were worse among patients treated in these hospitals. In centralized prefectures, the number of cases per hospital increased over time (7.2 in 2011 to 9.5 in 2016) while the crude operative mortality tended to decrease (3.4% in 2011 to 1.8% in 2016). The difference-in-difference estimator was 0.856 (95% confidence interval: 0.639-1.147, p = 0.298). CONCLUSION: The centralization of ultra-low-volume hospitals did not lead to a deterioration in the quality of care but rather an improving trend.

BACKGROUND: The benefits of centralization of pancreatic surgery have been documented, but policy differs between countries. This study aimed to model various centralization criteria for their effect on a nationwide cohort. METHODS: Data on all pancreatic resections performed between 2014 and 2016 were obtained from the Italian Ministry of Health. Mortality was assessed for different hospital volume categories and for each individual facility. Observed mortality and risk-standardized mortality rate (RSMR) were calculated. Various models of centralization were tested by applying volume criteria alone or in combination with mortality thresholds. RESULTS: A total of 395 hospitals performed 12 662 resections; 305 hospitals were in the very low-volume category (mean 2·6 resections per year). The nationwide mortality rate was 6·2 per cent, increasing progressively from 3·1 per cent in very high-volume to 10·6 per cent in very low-volume hospitals. For the purposes of centralization, applying a minimum volume threshold of at least ten resections per year would lead to selection of 92 facilities, with an overall mortality rate of 5·3 per cent. However, the mortality rate would exceed 5 per cent in 48 hospitals and be greater than 10 per cent in 17. If the minimum volume were 25 resections per year, the overall mortality rate would be 4·7 per cent in 38 facilities, but still over 5 per cent in 17 centres and more than 10 per cent in five. The combination of a volume requirement (at least 10 resections per year) with a mortality threshold (maximum RSMR 5 or 10 per cent) would allow exclusion of facilities with unacceptable results, yielding a lower overall mortality rate (2·7 per cent in 45 hospitals or 4·2 per cent in 76 respectively). CONCLUSION: The best performance model for centralization involved a threshold for volume combined with a mortality threshold.
ANTECEDENTES: Los beneficios de la centralización de la cirugía pancreática están bien documentados, pero la política de actuación difiere entre los países. Este estudio tuvo como objetivo desarrollar modelos de centralización basados en varios criterios y analizar su aplicación en una cohorte nacional. MÉTODOS: Los datos de todas las resecciones pancreáticas realizadas entre 2014 y 2016 se obtuvieron del Ministerio de Salud italiano. La mortalidad se evaluó para diferentes categorías del volumen hospitalario y para cada centro individualmente. Se calculó la mortalidad observada y la tasa estandarizada de riesgo de mortalidad (risk standardized mortality rate, RSMR). Se analizaron varios modelos de centralización aplicando criterios de volumen solos o en combinación con umbrales de mortalidad. RESULTADOS: Un total de 395 hospitales realizaron 12.662 resecciones; 305 de ellos pertenecían a la categoría de muy bajo volumen (media de 2,6 resecciones/año). La mortalidad nacional fue del 6,2%, aumentando progresivamente del 3,1% en los hospitales de muy alto volumen al 10,6% en los hospitales de muy bajo volumen. Para fines de centralización, al aplicar un umbral de volumen mínimo ≥ 10 resecciones/año, se seleccionarían 92 centros, con una mortalidad global del 5,3%. Sin embargo, la mortalidad sería > 5% en 48 hospitales y > 10% en 17 hospitales. Si el volumen mínimo fuera de 25 resecciones/año, la mortalidad global sería del 4,7% en 38 hospitales, pero aún > 5% en 17 centros y > 10% en seis centros. La combinación de un volumen necesario (≥ 10 resecciones/año) con un umbral de mortalidad (RSMR ≤ 5% o ≤ 10%) permitiría excluir hospitales con resultados inaceptables, determinando una mortalidad global más baja (2,7% en 45 hospitales o 4,2% en 76 hospitales, respectivamente). CONCLUSIÓN: El mejor modelo para la centralización de resecciones pancreáticas incluyó un umbral para el volumen hospitalario combinado con un umbral de mortalidad.

PURPOSE: Penile cancer is a rare but aggressive disease, often requiring a rapid and extensive surgical treatment of the primary tumor and staging or treatment of the inguinal lymph node basins. Current management and guidelines of the disease are mainly based on retrospective data, as there is a lack of controlled trials or large series. The purpose of this work is to review contemporary data on the impact of centralization and formation of rare disease networks on penile cancer care and outcomes. METHODS: This narrative, non-systematic review is based on publications retrieved by a PubMed and EMBASE search and on the current guidelines of the European Association of Urology, the National Institute for Health and Care Excellence, and the National Comprehensive Cancer network. RESULTS: The low case load, particularly in non-specialized centres, combined with limited evidence regularly results in a disparity between the treatment strategy and the guidelines. The suboptimal guideline adherence is specifically the case for organ-sparing surgery and surgical staging of the groin areas in selected cases. Treatment of the disease in high-volume referral centres has been shown to improve the use of organ-sparing surgery, the utilization of invasive lymph node staging in high-risk patients, and finally has resulted in increased survival rates. CONCLUSIONS: The management of penile cancer in disease networks and in countries where centralized healthcare is offered positively influences functional and oncological outcomes. We propose that governments and health care providers should be encouraged to centralize healthcare for rare tumors such as penile cancer.

OBJECTIVE: Several studies have revealed high volume centres have better outcomes in the treatment of abdominal aortic aneurysms (AAAs), thus supporting centralisation of this procedure into selected centres based on volume. To date however, the real benefit of centralisation of this pathology has not been well demonstrated. The aim of this study was to analyse the impact of centralisation in to high volume centres (defined as those performing more than 30 cases per year) on AAA treatment outcomes carried out in Catalonia (Spain). METHODS: Data were collected from official national registries (HDMBD) for AAA treated by endovascular aneurysm repair (EVAR) or open repair (OR) over a nine year period. Two time periods were selected for comparison: before centralisation (2009-2014) and after complete centralisation (2015-2017). The primary objective was to determine short term mortality (in hospital and 30 day mortality) and length of stay (LOS) after intact AAA (iAAA) and ruptured AAA (rAAA) repair, before and after centralisation. Uni- and multivariable analyses were performed in order to identify independent outcomes predictors. RESULTS: A total of 3 501 iAAAs, including 1 124 (32.1%) OR and 2377 (67.9%) EVAR, and 409 rAAAs, including 218 (53.3%) OR and 191 (46.7%) EVAR, were identified. After centralisation, there was a significant decrease in overall mortality in iAAA repair (4.7% vs. 2.0%, p < .001) and rAAA repair (53.1% vs. 41.9%, p = .028). Mortality reduction in iAAAs was significant for OR (8.7% vs. 3.6%, p = .005), but not for EVAR (2.2% vs. 1.5%, p = .25). Overall LOS decreased as well, mainly in iAAAs (9.49 ± 10.84 vs. 7.44 ± 12.23 days, p < .001), and in particular in elective EVAR (7.32 ± 7.73 vs. 6.00 ± 8.97 days, p < .001). Multivariable analysis was identified before the centralisation period as an independent predictor for both mortality (odds ratio 1.484, 95% CI 1.098-2.005, p = .010) and LOS (B coefficient 1.146, 95% CI 0.218-2.073, p = .016). CONCLUSION: The implementation of a country based centralisation programme for AAA treatment led to a significant reduction in short term mortality, for both iAAA and rAAA, and mainly for elective OR. LOS also significantly decreased, mainly for elective EVAR. These results support the benefit of centralisation of AAA repair procedures.

BACKGROUND: Authors in previous studies demonstrated that centralising acute stroke care is associated with an increased chance of timely Intra-Venous Thrombolysis (IVT) and lower costs compared to care at community hospitals. In this study we estimated the lower bound of the causal impact of centralising IVT on health and cost outcomes within clinical practice in the Northern Netherlands. METHODS: We used observational data from 267 and 780 patients in a centralised and decentralised system, respectively. The original dataset was linked to the hospital information systems. Literature on healthcare costs and Quality of Life (QoL) values up to 3 months post-stroke was searched to complete the input. We used Synthetic Control Methods (SCM) to counter selection bias. Differences in SCM outcomes included 95% Confidence Intervals (CI). To deal with unobserved heterogeneity we focused on recently developed methods to obtain the lower bounds of the causal impact. RESULTS: Using SCM to assess centralising acute stroke 3 months post-stroke revealed healthcare savings of $US 1735 (CI, 505 to 2966) while gaining 0.03 (CI, - 0.01 to 0.73) QoL per patient. The corresponding lower bounds of the causal impact are $US 1581 and 0.01. The dominant effect remained stable in the deterministic sensitivity analyses with $US 1360 (CI, 476 to 2244) as the most conservative estimate. CONCLUSIONS: In this study we showed that a centralised system for acute stroke care appeared both cost-saving and yielded better health outcomes. The results are highly relevant for policy makers, as this is the first study to address the issues of selection and unobserved heterogeneity in the evaluation of centralising acute stroke care, hence presenting causal estimates for budget decisions.

BACKGROUND: In the past two decades, the number of maternity hospitals in Finland has been reduced from 42 to 22. Notwithstanding the benefits of centralization for larger units in terms of increased safety, the closures will inevitably impair geographical accessibility of services. METHODS: This study aimed to employ a set of location-allocation methods to assess the potential impact on accessibility, should the number of maternity hospitals be reduced from 22 to 16. Accurate population grid data combined with road network and hospital facilities data is analyzed with three different location-allocation methods: straight, sequential and capacitated p-median. RESULTS: Depending on the method used to assess the impact of further reduction in the number of maternity hospitals, 0.6 to 2.7% of mothers would have more than a two-hour travel time to the nearest maternity hospital, while the corresponding figure is 0.5 in the current situation. The analyses highlight the areas where the number of births is low, but a maternity hospital is still important in terms of accessibility, and the areas where even one unit would be enough to take care of a considerable volume of births. CONCLUSIONS: Even if the reduction in the number of hospitals might not drastically harm accessibility at the level of the entire population, considerable changes in accessibility can occur for clients living close to a maternity hospital facing closure. As different location-allocation analyses can result in different configurations of hospitals, decision-makers should be aware of their differences to ensure adequate accessibility for clients, especially in remote, sparsely populated areas.

OBJECTIVE: Evidence favours centralisation of emergency care for specific conditions, but it remains unclear whether broader implementation improves outcomes and efficiency. Routine healthcare data examined consolidation of three district general hospitals with mixed medical admission units (MAU) into a single high-volume site directing patients from the ED to specialty wards with consultant presence from 08:00 to 20:00. METHODS: Consecutive unscheduled adult index admissions from matching postcode areas were identified retrospectively in Hospital Episode Statistics over a 3-year period: precentralisation baseline (from 16 June 2014 to 15 June 2015; n=18 586), year 1 postcentralisation (from 16 June 2015 to 15 June 2016; n=16 126) and year 2 postcentralisation (from 16 June 2016 to 15 June 2017; n=17 727). Logistic regression including key demographic covariates compared baseline with year 1 and year 2 probabilities of mortality and daily discharge until day 60 after admission and readmission within 60 days of discharge. RESULTS: Relative to baseline, admission postcentralisation was associated with favourable OR (95% CI) for day 60 mortality (year 1: 0.95 (0.88 to 1.02), p=0.18; year 2: 0.94 (0.91 to 0.97), p<0.01), mainly among patients aged 80+ years (year 1: 0.88 (0.79 to 0.97); year 2: 0.91 (0.87 to 0.96)). The probability of being discharged alive on any day since admission increased (year 1: 1.07 (1.04 to 1.10), p<0.01; year 2: 1.04 (1.02 to 1.05), p<0.01) and the risk of readmission decreased (year 1: 0.90 (0.87 to 0.94), p<0.01; year 2: 0.92 (0.90 to 0.94), p<0.01). CONCLUSION: A centralised site providing early specialist care was associated with improved short-term outcomes and efficiency relative to lower volume ED admitting to MAU, particularly for older patients.

In many countries, specialist cancer services are centralised to improve outcomes. We explored how centralisation affects the radical treatment of high-risk and locally advanced prostate cancer in the English NHS. 79,085 patients diagnosed with high-risk and locally advanced prostate cancer in England (April 2014 to March 2016) were identified in the National Prostate Cancer Audit database. Poisson models were used to estimate risk ratios (RR) for undergoing radical treatment by whether men were diagnosed at a regional co-ordinating centre ('hub'), for having surgery by the presence of surgical services on-site, and for receiving high dose-rate brachytherapy (HDR-BT) in addition to external beam radiotherapy by its regional availability. Men were equally likely to receive radical treatment, irrespective of whether they were diagnosed in a hub (RR 0.99, 95% CI 0.91-1.08). Men were more likely to have surgery if they were diagnosed at a hospital with surgical services on site (RR 1.24, 1.10-1.40), and more likely to receive additional HDR-BT if they were diagnosed at a hospital with direct regional access to this service (RR 6.16, 2.94-12.92). Centralisation of specialist cancer services does not affect whether men receive radical treatment, but it does affect treatment modality. Centralisation may have a negative impact on access to specific treatment modalities.

OBJECTIVE: The objective of this study was to review our institute's open aortic surgery volume experience and its impact on Accreditation Council for Graduate Medical Education trainees. METHODS: A review was conducted of the vascular surgery department's operative database for all cases that underwent aortic aneurysm repair, whether open aortic repair (OAR), endovascular aneurysm repair (EVAR), or fenestrated EVAR (FEVAR). We also reviewed our graduating trainees' case logs. In the setting of our regionalized referral center, all patients who underwent open or endovascular aortic intervention between 2010 and 2014 at our main campus were included. The total number of aortic procedures performed by our graduation trainees was determined. All aortic aneurysm interventions, both open and endovascular (both EVAR and FEVAR), were included. The main outcome measures were the total number of aortic interventions, any change in trends of intervention, and the total number of open aortic cases that our graduation trainees had. RESULTS: During the 5-year period analyzed, a total of 1389 abdominal aortic aneurysm repair procedures were performed by OAR, EVAR, and FEVAR. Of those, 462 were OARs, representing 33.2% of the total; 440 were EVARs, representing 31.6%; and 487 were FEVARs, representing 35.2%. For all OAR procedures, there was a significant increase in the proportion of these cases over time (P = .014). The total number of EVAR and FEVAR cases performed annually during this time did not change, whereas the number of OAR cases has increased. Of the OARs, 59.3% were performed for juxtarenal aneurysms, whereas 22.9% involved type IV thoracoabdominal aortic aneurysms. On average, graduating vascular surgery trainees performed 23.1 OARs before graduation (range, 19-26). CONCLUSIONS: In contrast to the documented national trend of decreased OAR, our institute continues to see increased OAR relative to EVAR and FEVAR. Moreover, we theorized that the preservation of OAR volume in our program and other similar institutions might offer a practical solution to the challenge of addressing vascular surgery training in aortic surgery by OAR, EVAR, and FEVAR. Inclusive discussions at the national and international levels are needed to reach consensus regarding the future of vascular surgery training and key issues, such as additional, mandatory, subspecialized training in OAR and FEVAR for both residents and fellows who wish to receive certification in OAR; creation of centers of excellence for open aortic surgery that would centralize OAR and direct trainees to those centers for their needed training; and possibly development of new training strategies whereby single cases can be shared among trainees with alternating roles as exposure and closure vs repair.

BACKGROUND: A retrospective study was performed to characterize trends in centralization of care and compliance with National Comprehensive Cancer Network (NCCN) guidelines for resected cholangiocarcinoma (CCA), and their impact on overall survival (OS). METHODS: Using the National Cancer Database (NCDB) 2004-2015 we identified patients undergoing resection for CCA. Receiver Operating Characteristic (ROC) analyses identified time periods and hospital volume groups for comparison. Propensity score matching provided case-mix adjusted patient cohorts. Cox hazard analysis identified risk factors for OS. RESULTS: Among the 40,338 patients undergoing resection for CCA, the proportion of patients undergoing surgery at high volume hospitals increased over time (25%-44%, p < 0.001), while the proportion of patients undergoing surgery at low volume hospitals decreased (30%-15%, p < 0.001). Using ROC analyses, a hospital volume of 14 operations/year was the most sensitive and specific value associated with mortality. Surgery at high volume hospitals [HR] = 0.92, 95% CI: 0.88-0.97, p < 0.001) and receipt of care compliant with NCCN guidelines (HR = 0.87, 95% CI: 0.83-0.91, p < 0.001) were independently associated with improved OS. CONCLUSIONS: Both centralization of surgery for CCA to high volume hospitals and increased compliance with NCCN guidelines were associated with significant improvements in overall survival.

BACKGROUND: Centralization of complex surgical care leads to increased travel distances for patients. We sought to determine if increased travel distance to the index hospital altered inpatient Visit rates following pancreatectomy. METHODS: Pancreatectomies from 2013-2016 were reviewed retrospectively from a single high-volume institution. Travel distance for 936 patients was determined, and patients were grouped by 50-mile increments. Visits (Observations or Readmissions) and corresponding reasons were gathered. RESULTS: 222 patients (23.7%) had a Visit to any hospital (AH) within 90 days postoperative; 195 (87.8%) were to the index hospital (IH). The <50 miles group had the highest Visit rate to AH (28.6% vs. 17.8% vs. 24.6%; P = 0.008) and the IH (26.9% vs. 15.2% vs. 20.6%; P = 0.002) compared to 50-100 and > 100 miles. This trend was statistically significant for Observations, but not Readmissions. Gastrointestinal (GI) complaints alone led to 20.7% patients requiring Visits to AH at 90-days, mostly in <50miles group for Visits and Observations at AH and IH. CONCLUSIONS: Patients closest to the IH had the highest Visit and Observation rate following pancreatectomy without affecting Readmission rate, with GI complaints as a driving factor. Inpatient education and outpatient symptom management may reduce repeat hospitalization.

BACKGROUND: With regionalization of care, patients often undergo treatment in institutions other than where the initial investigation is conducted. This study assessed the impact of a shared diagnostic imaging repository (SDIR) on processes of care and outcomes in hepato-pancreatico-biliary (HPB) cancer surgery. METHODS: Provincial administrative datasets were linked to study HPB cancer patients operated at a regional cancer centre (2003-2014). SDIR and non-SDIR groups were based on where initial imaging (CT or MRI) was conducted. Outcomes were repeat imaging before surgery and wait times for surgery from initial imaging and surgical consultation. RESULTS: Of 839 patients, 474 were from SDIR institutions. Fewer SDIR patients underwent any repeat imaging (55.9% vs. 75.3%; p < 0.01) and repeat imaging with same modality and protocol (24.7% vs. 43.0%; p < 0.01). Median wait time to surgery from initial imaging (64 Vs. 79 days; p < 0.01) and surgical consultation (39 Vs. 45 days; p = 0.046) was shorter with SDIR. SDIR patients had lower adjusted odds of any repeat imaging (OR 0.20 [0.14-0.30]), and repeat imaging with same modality and protocol (OR 0.58 [0.41-0.80]). CONCLUSION: Radiology sharing with SDIR reduced repeat imaging for HPB cancer surgery, including potentially redundant repeat imaging with same protocol, and shortened wait time to surgical care.

BACKGROUND: Centralization of pancreatic resections is advocated due to a volume-outcome association. Pancreatic surgery is in Norway currently performed only in five teaching hospitals. The aim was to describe the short-term outcomes after pancreatoduodenectomy (PD) within the current organizational model and to assess for regional disparities. METHODS: All patients who underwent PD in Norway between 2012 and 2016 were identified. Mortality (90 days) and relaparotomy (30 days) were assessed for predictors including demographic data and multi-visceral or vascular resection. Aggregated length-of-stay and national and regional incidences of the procedure were also analysed. RESULTS: A total of 930 patients underwent PD during the study period. In-hospital mortality occurred in 20 patients (2%) and 34 patients (4%) died within 90 days. Male gender, age, multi-visceral resection and relaparotomy were independent predictors of 90-day mortality. Some 131 patients (14%) had a relaparotomy, with male gender and multi-visceral resection as independent predictors. There was no difference between regions in procedure incidence or 90-day mortality. There was a disparity within the regions in the use of vascular resection (p = 0.021). CONCLUSION: The short-term outcomes after PD in Norway are acceptable and the 90-day mortality rate is low. The outcomes may reflect centralization of pancreatic surgery.

BACKGROUND AND PURPOSE: In Orange County, California, patients with suspected acute stroke are taken to stroke neurology receiving centers that are designated by County Emergency Medical Services authorities as either hubs or spokes based on endovascular treatment capability. We examined relationships between stroke details, reperfusion therapies, hospital transfers, and their change over time. METHODS: All patients from January 1, 2013, to December 31, 2015, for whom 911 was called within 7 hours of onset in whom Emergency Medical Services personnel suspected acute stroke were evaluated. RESULTS: Among 6132 patients, 3924 (64%) had confirmed diagnosis of stroke (74% ischemic/26% hemorrhagic), yielding diagnostic precision of 64% in the field. Of the 2892 patients with acute ischemic stroke, acute reperfusion therapy was given to 29.2% (21.7% intravenous tPA [tissue-type plasminogen activator] only and 7.5% endovascular treatment). Rates of endovascular treatment of patients with ischemic stroke increased over time, more than doubling from 5.6% in 2013 to 12.5% (odds ratio per 3-month quarter=1.09; 95% confidence interval, 1.04-1.14; P<0.0001). Only 3.4% of patients with acute ischemic stroke were transferred from a spoke to a hub hospital; transfer rates were inversely related to age (P<0.0001), and reperfusion therapy rates did not vary according to transfer status. CONCLUSIONS: Favorable features of this acute stroke care system include reperfusion therapy in 29.2% of patients with ischemic stroke and substantial increases in endovascular treatment rates over time. Continued efforts to optimize acute stroke systems of care can be directed toward improving access to best acute stroke therapies.

OBJECTIVES: To critically assess centralization policies for highly specialized surgeries in Europe and North America and propose recommendations. BACKGROUND/METHODS: Most countries are increasingly forced to maintain quality medicine at a reasonable cost. An all-inclusive perspective, including health care providers, payers, society as a whole and patients, has ubiquitously failed, arguably for different reasons in environments. This special article follows 3 aims: first, analyze health care policies for centralization in different countries, second, analyze how centralization strategies affect patient outcome and other aspects such as medical education and cost, and third, propose recommendations for centralization, which could apply across continents. RESULTS: Conflicting interests have led many countries to compromise for a health care system based on factors beyond best patient-oriented care. Centralization has been a common strategy, but modalities vary greatly among countries with no consensus on the minimal requirement for the number of procedures per center or per surgeon. Most national policies are either partially or not implemented. Data overwhelmingly indicate that concentration of complex care or procedures in specialized centers have positive impacts on quality of care and cost. Countries requiring lower threshold numbers for centralization, however, may cause inappropriate expansion of indications, as hospitals struggle to fulfill the criteria. Centralization requires adjustments in training and credentialing of general and specialized surgeons, and patient education. CONCLUSION/RECOMMENDATIONS: There is an obvious need in most areas for effective centralization. Unrestrained, purely "market driven" approaches are deleterious to patients and society. Centralization should not be based solely on minimal number of procedures, but rather on the multidisciplinary treatment of complex diseases including well-trained specialists available around the clock. Audited prospective database with monitoring of quality of care and cost are mandatory.

BACKGROUND AND AIMS: The potential benefit of the centralization of Bariatric surgery (BS) remains debated. The aim of this study was to evaluate the impact on 90-day mortality of an innovative organization aiming at centralizing the care of severe postoperative complications of BS. STUDY DESIGN: The centralization of care for postoperative complication after BS was implemented by French Authorities in 2013 in the Nord-Pas-de-Calais Region, France. This unique formalized network (OSEAN), coordinated by 1 tertiary referral center, enrolled all regional institutions performing bariatric surgery. Data were extracted from the medico-administrative database providing information on all patients undergoing BS between 2009 and 2016 in OSEAN (n = 22,928) and in Rest of France (n = 288,942). The primary outcome was the evolution of 90-day mortality before and after the implementation of this policy. Rest of France was used as a control group to adjust the results to improvement with time of BS outcomes. RESULTS: The numbers of primary procedure and reoperations increased similarly before and after 2013 within OSEAN and in Rest of France. The 90-day mortality rate became significantly lower within OSEAN than in the rest of France after 2013 (0.03% vs 0.08%, P < 0.01). This difference was confirmed in multivariate analysis after adjustment to the procedure specific mortality (P < 0.04). The reduction of 90-day mortality was most visible for sleeve gastrectomy. CONCLUSION: The implementation of centralized care for early postoperative complications after BS in OSEAN was associated with reduced 90-day mortality. Our results indicate that this reduction was not due to a lower incidence of complications but to the improvement of their management.

BACKGROUND: In England in 2001 oesophagogastric cancer surgery was centralized. The aim of this study was to evaluate whether centralization of oesophagogastric cancer to high-volume centres has had an effect on mortality from different emergency upper gastrointestinal conditions. METHODS: The Hospital Episode Statistics database was used to identify patients admitted to hospitals in England (1997-2012). The influence of oesophagogastric high-volume cancer centre status (20 or more resections per year) on 30- and 90-day mortality from oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer was analysed. RESULTS: Over the study interval, 3707, 12 441 and 56 822 patients with oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer respectively were included. There was a passive centralization to high-volume cancer centres for oesophageal perforation (26·9 per cent increase), paraoesophageal hernia (19·5 per cent increase) and perforated peptic ulcer (23·0 per cent increase). Management of oesophageal perforation in high-volume centres was associated with a reduction in 30-day (HR 0·58, 95 per cent c.i. 0·45 to 0·74) and 90-day (HR 0·62, 0·49 to 0·77) mortality. High-volume cancer centre status did not affect mortality from paraoesophageal hernia or perforated peptic ulcer. Annual emergency admission volume thresholds at which mortality improved were observed for oesophageal perforation (5 patients) and paraoesophageal hernia (11). Following centralization, the proportion of patients managed in high-volume cancer centres that reached this volume threshold was 88·0 per cent for oesophageal perforation, but only 30·3 per cent for paraoesophageal hernia. CONCLUSION: Centralization of low incidence conditions such as oesophageal perforation to high-volume cancer centres provides a greater level of expertise and ultimately reduces mortality.
