RESUMEN
BACKGROUND: Several randomized controlled trials (RCTs) have demonstrated improved short-term outcomes of totally minimally invasive esophagectomy (TMIE) compared with open esophagectomy (OE); however, to what extent these outcomes can be extrapolated to a national level remains debatable. OBJECTIVE: The aim of this study was to evaluate, on a nationwide basis, the short-term outcomes of TMIE and to analyze these results within the context of previously implemented hybrid minimally invasive esophagectomy (HMIE). METHODS: All consecutive patients who underwent a curative Ivor Lewis esophagectomy in France between 2017 and 2019 were included in this retrospective cohort study. The primary endpoint was to compare 90-day postoperative mortality (POM) between OE, HMIE, and TMIE, while secondary endpoints were defined as the rate of postoperative complications. A matched and multivariate analysis was adjusted for confounding factors. RESULTS: Overall, 2675 patients were included (1003 OE vs. 1498 HMIE vs. 174 TMIE). In every center where TMIE was performed, HMIE had been previously adopted. The matched 90-day POM rate in the TMIE group was significantly lower compared with the OE group (2.3% vs. 6.3%, p = 0.046) but not compared with the HMIE group (2.3% vs. 4.9%, p = 0.156). There was no significant difference between TMIE and OE, or TMIE and HMIE, regarding the 30-day fistula rate (21.8% vs. 17%, p = 0.176; and 21.8% vs. 21.3%, p = 0.88, respectively). TMIE was associated with a reduced rate of pulmonary complications compared with OE (33.9% vs. 44%, p = 0.027) and HMIE (33.9% vs. 42.8%, p = 0.05). Low-volume centers were identified as a negative predictive factor for 90-day POM (odds ratio 1.89, 95% confidence interval 1.3-2.75, p = 0.001). CONCLUSION: TMIE is associated with a lower 90-day POM rate compared with OE and offers reduced rates of pulmonary complications compared with OE and HMIE. After previous adoption of the HMIE technique, TMIE can be safely implemented in high-volume centers nationwide.

PURPOSE: To compare the incidence and the safety outcomes associated with active stone removal procedure (ASRP) between neurological and non-neurological patients. MATERIALS AND METHODS: The present study was conducted using the data issued from the French National Health Data Base. All patients that have been hospitalized to undergo an ASRP between January 1 2012 and December 31 2018 were included and allocated to four neurological groups (multiple sclerosis, spinal dysraphism, paraplegia, tetraplegia) and one non-neurological group. The primary outcome was the rate of patients hospitalized at least once to undergo an ASRP over the study period. The secondary outcomes included the type of ASRP performed, the length of hospital stay, the rates of post-operative UTI, of early re-admission and re-treatments. Multivariate logistic regression was used to estimate odd ratios, the four neurological groups being compared to the non-neurological group. RESULTS: During the study period, 45,745,055 patients were hospitalised, with 151,850 of them presenting with an underlying neurological disease. Among the non-neurological patients, 0.89% underwent an ASRP, while 1.39% neurological patients did. Neurological patients presented with a lower rate of ESWL associated with a higher rate of PCNL, while the length of hospital stay, the rate of post-operative UTI, of early re-admission and of re-treatment were systematically increased (p < 0.001), when compared to non-neurological patients, regardless of the type of ASRP considered. CONCLUSIONS: The results presented here confirm and clarify the incidence and the safety outcomes associated with ASRP within the neurological population and advocate for the emergence of a dedicated research field focusing on neuro-urolithiasis.

BACKGROUND: There is growing evidence that failure to rescue (FTR) is an important factor of postoperative mortality (POM) after rectal cancer surgery and surgical approach modified post-operative outcomes. However, the impact of laparoscopy on FTR after proctectomy for rectal cancer remains unknown. The aim of this study was to compare the rates of postoperative complications and FTR after laparoscopy vs open proctectomy for cancer. METHODS: All patients who underwent proctectomy for rectal cancer between 2012 and 2016 were included. FTR was defined as the 90-day POM rate among patients with major complications. Outcomes of patients undergoing open or laparoscopic rectal cancer surgery were compared after 1:1 propensity score matching by year of surgery, hospital volume, sex, age, Charlson score, neoadjuvant chemotherapy, tumor localization and type of anastomosis. RESULTS: Overall, 44,536 patients who underwent proctectomy were included, 7043 of whom (15.8%) developed major complications. The rates of major complications, POM and FTR were significantly higher in open compared to laparoscopic procedure (major complications: 19.2% vs 13.7%, p < 0.001; POM: 5.4% vs 2.3%, p < 0.001; FTR: 13.6% vs 8.3%, p < 0.001; respectively). After matching, open and laparoscopic groups were comparable. Multivariate analysis showed that age, Charlson score, sphincter-preserving procedure and surgical approach were predictive factors for FTR. Open proctectomy was found to be a risk factor for FTR (OR 1.342, IC95% [1.066; 1.689], p = 0.012) compared to laparoscopic procedure. CONCLUSION: When complications occurred, patients operated on by open proctectomy were more likely to die.

National and international guidelines about thyroid surgery seem to be moving more and more towards less radical surgical procedures but everyday practice does not seem to always align with them. We describe for the first time the role of non-surgical parameters in the surgeon's choice for thyroid surgery. OBJECTIVE: The ain of this study was to describe thyroid surgery and to identify the factors leading to either a total or a partial thyroidectomy regardless of the severity of the thyroid disease. SUMMARY BACKGROUND DATA: National and international guidelines about thyroid surgery seem to be moving more and more toward less radical surgical procedures but everyday practice does not seem to always align with them. METHODS: We based this nationwide retrospective cohort study on a national database that compiles discharge abstracts for every admission for thyroidectomy to French acute healthcare facilities (PMSI database 2010 to 2019). RESULTS: In this study, 375,810 patients (male: 23%; age = 53â±â15 years) had a thyroidectomy (partial: 28%) for cancer (17%), hyperthyroidism (16%), nonfunctioning goiter (64%), or other (3%). We noticed a global trend toward more partial thyroidectomy (P < 0.001) with a significant increase in the proportion of lobectomy in the post-ATA recommendations' period (P < 0.001) as well as in the "French Levothyrox crisis" period, in which we saw an unexpected rise of adverse events notifications associated with the marketing of a new formula of Levothyrox (P < 0.001) amid widespread media coverage. In a multivariate analysis, we also identified that complete resection was more frequently performed in centers with a caseload >40/year [P < 0.001, odds ratio (OR) = 1.48], for obese patients (body mass index >30âkg/m2; P < 0.001, OR = 1.42), and according to the indication of surgery (OR benign = 1, OR cancer = 2.25, OR hyperthyroidism = 4.13). CONCLUSION: We describe for the first time the role of non-surgical parameters in the surgeon's choice for thyroid surgery.

OBJECTIVES: Analyze a multicenter cohort of deceased patients after pancreatectomy in high-volume centers in France by performing a root-cause analysis (RCA) to define the avoidable mortality rate. BACKGROUND: Despite undeniable progress in pancreatic surgery for over a century, postoperative outcome remains particularly worse and could be further improved. METHODS: All patients undergoing pancreatectomy between January 2015 and December 2018 and died postoperatively within 90âdays after were included. RCA was performed in 2 stages: the first being the exhaustive collection of data concerning each patient from preoperative to death and the second being blind analysis of files by an independent expert committee. A typical root cause of death was defined with the identification of avoidable death. RESULTS: Among the 3195 patients operated on in 9 participating centers, 140 (4.4%) died within 90âdays after surgery. After the exclusion of 39 patients, 101 patients were analyzed. The cause of death was identified in 90% of cases. After RCA, mortality was preventable in 30% of cases, mostly consequently to a preoperative assessment (disease evaluation) or a deficient postoperative management (notably pancreatic fistula and hemorrhage). An inappropriate intraoperative decision was incriminated in 10% of cases. The comparative analysis showed that young age and arterial resection, especially unplanned, were often associated with avoidable mortality. CONCLUSIONS: One-third of postoperative mortality after pancreatectomy seems to be avoidable, even if the surgery is performed in high volume centers. These data suggest that improving postoperative pancreatectomy outcome requires a multidisciplinary, rigorous, and personalized management.

OBJECTIVE: Evaluate at a national level the postoperative mortality (POM), major morbidity (MM) and failure-to-rescue (FTR) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) across time and according to hospital-volume. BACKGROUND: CRS/HIPEC is an effective therapeutic strategy commonly used to treat peritoneal surface malignancies. However, this aggressive approach has the reputation to be associated with a high POM and MM. METHODS: All patients treated with CRS/HIPEC between 2009 and 2018 in France were identified through a national medical database. Patients and perioperative outcomes were analyzed. A cut-off value of the annual CRS/HIPEC caseload affecting the 90-day POM was calculated using the Chi-squared Automatic Interaction Detector method. A multivariable logistic model was used to identify factors mediating 90-day POM. RESULTS: A total of 7476 CRS/HIPEC were analyzed. Median age was 59 years with a mean Elixhauser comorbidity index of 3.1, both increasing over time (P < 0.001). Ninety-day POM was 2.6%. MM occurred in 44.2% with a FTR rate of 5.1%. The threshold of CRS/HIPEC number per center per year above which the 90-day POM was significantly reduced was 45 (3.2% vs 1.9%, P = 0.01). High-volume centers had more extended surgery (P < 0.001) with increased MM (55.8% vs 40.4%, P < 0.001) but lower FTR (3.1% vs 6.3%, P = 0.001). After multivariate analysis, independent factors associated with 90-day POM were: age >70 years (P = 0.002), Elixhauser comorbidity index ≥8 (P = 0.006), lower gastro-intestinal origin, (P < 0.010), MM (P < 0.001), and <45 procedures/yr (P = 0.002). CONCLUSION: In France, CRS/HIPEC is a safe procedure with an acceptable 90-day POM that could even be improved through centralization in high-volume centers.

OBJECTIVES: We aimed to analyze the outcomes of interhospital transfer (IHT) patients after pancreatectomy, describe the characteristics of transferring hospitals, and determine the risk factors of transfer and mortality in IHT patients. BACKGROUND: Implementation of the centralization process is complex and currently unrealized in France. Alternatively, centralization of patients with postoperative complications to high volume centers could reduce postoperative mortality (POM) and failure to rescue (FTR). METHODS: All patients undergoing pancreatectomy for cancer between 2012 and 2018 were included. Hospitals' and patients' characteristics were analyzed to determine predictive factors for transfer and FTR. POM was defined as death occurring during the hospital stay and FTR as POM rate among patients with major complications. RESULTS: Overall, 19,938 patients who underwent pancreatectomy were included, 1164 (5.8%) of whom were transferred. IHT patients were mostly originated from low volume hospitals (60.3% vs 39.7%), from facilities without intensive care unit (46.9% vs 22.4%) or interventional radiology (22.8% vs 12.8%). Among IHT patients, 51% underwent reoperation before transfer and 34.9% experienced hemorrhage complications. The POM was 5.2% and varied significantly between transfer and nontransfer patients (13.3% vs 4.7%, P < 0.001). Patients who experienced major complications after pancreatectomy in low volume hospitals had greater odds of being transferred (Odds Ratio (OR) = 2.46, confidence intervals (CI)95%[1.734; 3.516], P < 0.001). Also, transfer (OR = 2.17, CI95%[1.814; 2.709], P < 0.001) and especially transfer after pancreatectomy in low volume centers (OR = 3.76, CI95%[2.83; 5.01], P < 0.001) were associated with increased FTR rates. CONCLUSIONS: Transfers after pancreatectomy were associated with high rates of FTR, especially for patients undergoing surgery in low volume hospitals. Local expertise, resources, and volume of hospitals are mandatory to provide appropriate care after pancreatectomy.

BACKGROUND: Surgical removal of hyperfunctional parathyroid gland is the definitive treatment for primary hyperparathyroidism (pHPT). Postoperative follow-up shows variability in persistent/recurrent disease rate throughout different centers. OBJECTIVE: To evaluate the incidence of redo surgery after targeted parathyroidectomy for pHPT. METHODS: We performed a nationwide retrospective cohort study on the "Programme de Medicalisation des Systemes d'Information," the French administrative database that collects information on all healthcare facilities' discharges. We extracted data from 2009 to 2018 for all patients who underwent parathyroidectomy for pHPT between January 2011 to December 2016. The primary outcome was the reoperation rate within 2 years since first surgery. Patients who had a first attempt of surgery within the previous 24 months, familial hyperparathyroidism, multiglandular disease, and renal failure were excluded. Results were adjusted according to sex and the Elixhauser Comorbidity Index. Operative volume thresholds to define high-volume centers were achieved by the Chi-Squared Automatic Interaction Detector method. RESULTS: In the study period, 13,247 patients (median age 63, F/M=3.6) had a focused parathyroidectomy by open (88.7%) or endoscopic approach. Need of remedial surgery was 2.8% at 2 years. In multivariate analysis, factors predicting redo surgery were: cardiac history (P=0.008), obesity (P=0.048), endoscopic approach (P=0.005), and low-volume center (P<0.001). We evaluated that an annual caseload of 31 parathyroidectomies was the best threshold to discriminate high-volume centers and carries the lowest morbidity/failure rate. CONCLUSION: Although focused parathyroidectomy represents a standardized operation, cure rate is strongly associated with annual hospital caseload, type of procedure (endoscopic), and patients' features (obesity, cardiac history). Patients with risk factors for redo surgery should be considered for an open surgery in a high-volume center.

BACKGROUND: It remains to be established whether centralization to high volume centers is essential for all patients undergoing pancreatic surgery. The aims of this study were to identify the optimal cut-off volume to optimize patient outcomes and to determine if patient comorbidity affected the volume-outcome relationship. METHODS: Patients undergoing pancreatectomy from 2012 to 2015 were retrospectively identified (n = 12 333) in the French nationwide database. The 90-day Post-Operative Mortality (POM) was analyzed according to hospital volume of pancreatectomy (very low:<10, Low:10-19, High:20-49 and very high:≥50 resections/year) and Charlson Comorbidity Index (ChCI). RESULTS: The overall POM was 6.9%. The cut-off of 20 pancreatic resections per year was identified as predictor of POM. Compared to high volume centers, POM was significantly higher in low and very low volume centers whatever the ChCl. Regarding surgical procedures, there was a significant decrease in POM with increasing hospital volume only after pancreaticoduodenectomy regardless of the ChCl. On multivariable analysis, low and very low volume centers were independently associated with increased mortality rates. CONCLUSION: The optimal cut-off of annual caseload was 20 pancreatic resections. POM following pancreaticoduodenectomy is high in low and very low volume centers independently of ChCl, suggesting that this procedure should be centralized.

OBJECTIVES: We aimed to examine whether the improved outcome of a digestive cancer procedure in high-volume hospitals is specific or correlates with that of other digestive cancer procedures, and determine if the discriminant cut-off of hospital volume may influence postoperative mortality (POM) regardless of the procedure. BACKGROUND: Performing complex surgeries in tertiary centers is associated with improved outcome. However, the association between POM and hospital volume of nonspecific procedures is unknown. METHODS: Patients who underwent colectomy, proctectomy, esophagectomy, gastrectomy, pancreatectomy, and hepatectomy for cancer between 2012 and 2017 were identified in the French nationwide database. Chi-square automatic interaction detector was used to identify the cut-off values of the annual caseload affecting the 90-day POM. A common threshold was estimated by minimization of chi-square distance taking into account the specific mortality of each procedure. RESULTS: Overall, 225,752 patients were identified. Hospitals were categorized according to the procedure volume (colectomy: ≥80âcases/yr, proctectomy: ≥35/yr, esophagectomy: ≥41/yr, gastrectomy: ≥16/yr, pancreatectomy: ≥26/yr, and hepatectomy: ≥76/yr). The overall 90-day POM was 5.1% and varied significantly with volume. The benefits of high volume were transferable across procedures. High-volume hospitals for colorectal cancer surgery significantly influenced the risk of death after hepatectomy (P < 0.001) and pancreatectomy (P < 0.001). The common threshold for all procedures that influenced POM was 199âcases/yr (odds ratio 1.29, P < 0.001). CONCLUSION: In digestive cancer surgery, the volume-POM relationship of one procedure was associated with the volume of other procedures. Thus, tertiary hospitals should be defined according to the common threshold of different procedures.

OBJECTIVE: To explore the determinants of postoperative outcomes of adrenal surgery in order to build a proposition for healthcare improvement. SUMMARY OF BACKGROUND DATA: Adrenalectomy is the recommended treatment for many benign and malignant adrenal diseases. Postoperative outcomes vary widely in the literature and their determinants remain ill-defined. METHODS: We based this retrospective cohort study on the "Programme de médicalisation des systèmes d'information" (PMSI), a national database that compiles discharge abstracts for every admission to French acute health care facilities. Diagnoses identified during the admission were coded according to the French adaptation of the 10th edition of the International Classification of Diseases (ICD-10). PMSI abstracts for all patients discharged between January 2012 and December 2017 were extracted. We built an Adrenalectomy-risk score (ARS) from logistic regression and calculated operative volume and ARS thresholds defining high-volume centers and high-risk patients with the CHAID method. RESULTS: During the 6-year period of the study, 9820 patients (age: 55â±â14; F/M = 1.1) were operated upon for adrenal disease. The global 90-day mortality rate was 1.5% (n = 147). In multivariate analysis, postoperative mortality was independently associated with age ≥75 years [odds ratio (OR): 5.3; P < 0.001], malignancy (OR: 2.5; P < 0.001), Charlson score ≥2 (OR: 3.6; P < 0.001), open procedure (OR: 3.2; P < 0.001), reoperation (OR: 4.5; P < 0.001), and low hospital caseload (OR: 1.8; P = 0.010). We determined that a caseload of 32âpatients/year was the best threshold to define high-volume centers and 20 ARS points the best threshold to define high-risk patients. CONCLUSION: High-risk patients should be referred to high-volume centers for adrenal surgery.

OBJECTIVE: To evaluate the influence of hospital volume on failure-to-rescue (FTR) after pancreatectomy in France. BACKGROUND: There are growing evidences that FTR is an important source of postoperative mortality (POM) after pancreatectomy. However, few studies have analyzed the volume-FTR relationship following pancreatic surgery. METHODS: All patients undergoing pancreatectomy between 2012 and 2015 were included. FTR is defined as the 90-day POM rate among patients with major complications. According to the spline model, the critical cutoff was 20 resections per year and hospitals were divided into low (<10âresections/an), intermediate (11-19âresections/yr), and high volume centers (≥20âresections/yr). RESULTS: Overall, 12,333 patients who underwent pancreatectomy were identified. The POM was 6.9% and decreased significantly with increased hospital volume. The rate of FTR was 14.5% and varied significantly with hospital volume (18.3% in low hospital volume vs 11.9% in high hospital volume, P < 0.001), age (P < 0.001) and ChCl (CCl0-2: 11.5%, ChCl3: 13%, CCl ≥4:18.6%; P < 0.001). FTR for renal failure was the highest of all complications (40.2%), followed by postoperative shock (36.4%) and cardiac complications (35.1%). The FTR was significantly higher in low and intermediate compared with high volume hospitals for shock, digestive, and thromboembolic complications and reoperation. In multivariable analysis, intermediate (OR = 1.265, CI95%[1.103-1.701], P = 0.045) and low volume centers (OR = 1.536, CI95%[1.165-2.025], P = 0.002) were independently associated with increased FTR rates. CONCLUSION: FTR after pancreatectomy is high and directly correlated to hospital volume, highlighting variability in the management of postoperative complications. Measurement of the FTR rate should become a standard for quality improvement programs.

OBJECTIVE: To identify the impact of hospital volume according to Charlson Comorbidity Index (ChCI) on postoperative mortality (POM) after rectal cancer surgery. BACKGROUND: A volume-outcome relationship has been established in complex surgical procedures. However, little is known regarding the impact of hospital volume on POM according to patients' comorbidities after rectal cancer surgery. METHODS: All patients undergoing proctectomy for cancer from 2012 to 2016 were identified in the French nationwide database. Patient condition was assessed on the basis of the validated ChCl and was stratified into 3 groups according to the score (0-2, 3, and ≥4). Chi-square automatic interaction detector (CHAID) was used to identify the cut-off values of the annual proctectomy caseload affecting the 90-day POM. The 90-day POM was analyzed according to hospital volume (low: <10, intermediate: 10-40, and high: ≥41âcases/yr) and ChCI. RESULTS: Among 45,569 rectal cancer resections, the 90-day POM was 3.5% and correlated to ChCI (ChCI 0-2: 1.9%, ChCI 3: 4.9%, ChCI ≥4: 5.8%; P < 0.001). There was a linear decrease in POM with increasing hospital volume (low: 5.6%, intermediate: 3.5%, high: 1.9%; P < 0.001). For low-risk patients (ChCl 0-2), 90-day POM was significantly higher in low and intermediate hospital volume compared with high hospital volume centers (3.2% and 1.8% vs 1.1%; P < 0.001). A significant decrease in postoperative hemorrhage complication rates was observed with increasing center volume (low: 13.3%, intermediate: 11.9%, and high: 9.4%; P < 0.001). After multivariable analysis, proctectomy in low [odds ratio (OR) 2.1, 95% confidence interval (CI) 1.71-2.58, P < 0.001] and intermediate (OR 1.45, 95% CI 1.2-1.75, P < 0.001) hospital volume centers were independently associated with higher risk of mortality. CONCLUSION: The POM after proctectomy for rectal cancer is strongly associated with hospital volume independent of patients' comorbidities. To improve postoperative outcomes, rectal surgery should be centralized.

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.

INTRODUCTION: Total alkaline phosphatase (tALP) levels rise physiologically in maternal serum during pregnancy, and excessively so in certain conditions. However, current reference values are dated, nonlinear, and based on small samples. Factors related to variation in tALP remain unexplained. Thus, our goals in this study were to establish a physiological development curve for tALP within low-risk pregnancies and to evaluate the factors influencing tALP values. METHODS: This was a single-center, retrospective, observational study. All patients who delivered a live singleton infant at our center from January 1, 2011 to May 31, 2019, and had a tALP assay during pregnancy, were included regardless of the gestational age at which the assay was conducted. RESULTS: A total of 2415 pregnancies were included. Median tALP decreased during the first trimester, it increased slightly during the second trimester, and then increased sharply during the third trimester. Factors associated with a significant increase in tALP were chronic histiocytic intervillositis, cholestasis, multiple pregnancies, liver disease, preeclampsia, smoking, and low weight for gestational age. Conversely, gestational diabetes was associated with a discrete decrease in tALP. DISCUSSION: Our large sample allowed establishment of tALP reference curves based on gestational age. To interpret these results more thoroughly, factors that influence tALP rates should be further scrutinized.

INTRODUCTION: Clinical pathways represents the sequence of interventions from which the patients benefit during their encounters with health care structures. There are several complex issues which make it difficult to represent these pathways (e.g. high numbers of patients, heterogeneity of variables). METHODS: We developed a tool to automate the representation of clinical pathways, from an individual and population points of view, and based on the OMOP CDM. The tool implemented the Sankey diagram in three stages: (i) data extraction, (ii) generation of individual sequence of steps and (iii) aggregation of sequence to obtain the population-level diagram. We tested the tool with three surgery procedures: the total hip replacement, the coronary bypass and the transcatheter aortic valve implantation. RESULTS: The tool provided different ways of visualizing pathways depending on the question asked: a pathway before a surgery, the pathway of deceased patients or the complete pathway with different steps of interest. DISCUSSION: We proposed a tool automating the representation of the clinical pathways, and reducing complexity of visualization. Representations are detailed from an individual and population points of view. It has been tested with three surgical procedures. The tool functionalities will be extended to cover a greater number of use cases.

OBJECTIVE: The centralization of complex surgical procedures is associated with better postoperative outcomes. However, little is known about the impact of hospital volume on the outcome after distal pancreatectomy. METHODS: Using the French national hospital discharge database, we identified all patients having undergone distal pancreatectomy in France between 2012 and 2015. A spline model was applied to determine the caseload cut-off in annual distal pancreatectomy that influenced 90-day postoperative mortality. RESULTS: A total of 3314 patients were identified. Use of a spline model did not reveal a cut-off in the annual distal pancreatectomy caseload. By taking the median number of distal pancreatectomy (n = 5) and the third quartile (n = 15), we stratified centers into low, intermediate, and high hospital volume groups. The overall postoperative mortality rate was 3.0% and did not differ significantly between these groups. In a multivariable analysis, age, Charlson comorbidity score, septic complications, hemorrhage, shock, and reoperation were independently associated with a greater overall risk of death. However, hospital volume had no impact on mortality after distal pancreatectomy (odds ratio, 0.954; 95% confidence interval, 0.552-1.651, P = 0.867). CONCLUSIONS: Hospital volume does not seem to influence mortality after distal pancreatectomy in France, and centralization may not necessarily improve outcomes.

BACKGROUND: The long-term collection of population-based data should improve our knowledge of the contribution of trend in cardiovascular risk factors to the steady fall in mortality associated with coronary heart disease in high-income countries. AIMS: To assess long-term time trends in the prevalence of cardiovascular risk factors, estimated coronary heart disease risk and mortality between 1986 and 2013 in the Lille urban area (northern France). METHODS: We studied representative samples of inhabitants of the Lille urban area (aged 40-64 years) in 1986-1988 (n=860), 1995-1996 (n=1021), 2005-2007 (n=1021) and 2011-2013 (n=1636), together with data from the Lille MONICA registry. RESULTS: In men, the age-standardized prevalence fell between 1986 and 2013 from 70.5% to 42.5% for hypertension, from 71.1% to 58.3% for dyslipidaemia and from 44.1% to 24.7% for smoking (all P<0.001). The prevalence of being overweight increased from 59.6% to 65.1% (P<0.05). In women, the prevalences decreased from 56.6% to 34.3% for hypertension and from 60.9% to 42.2% for dyslipidaemia (both P<0.001). The prevalences of smoking (17%) and being overweight (50%) were stable. The mean 10-year (95% confidence interval) predicted risk of fatal coronary heart disease (estimated with the Systematic Coronary Risk Evaluation equation) decreased by 2.02% (1.78-2.25%) per year for men and by 1.55% (1.32-1.78%) for women. The observed coronary mortality rate fell by 2.6% (2.2-3.0%) in men and 2.8% (1.9-3.6%) in women. CONCLUSIONS: Prevalences of main risk factors and estimated coronary mortality risk decreased concomitantly with the observed coronary mortality - indicating that primary prevention made a major contribution to the decrease in mortality.
