[PMID: 39362415 DOI: 10.1016/j.jvs.2024.09.028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 09/13/2024] [Accepted: 09/23/2024] [Indexed: 10/05/2024]
Abstract
OBJECTIVE Patients with peripheral artery disease (PAD) undergo lower extremity revascularization (LER) for symptomatic relief or limb salvage. Despite LER, patients remain at increased risk of platelet-mediated complications, such as major adverse cardiac and limb events (MACLE). Platelet activity is associated with cardiovascular events; yet little is known about the dynamic nature of platelet activity over time. We therefore investigated the change in platelet activity over time and its association with long-term cardiovascular risk. METHODS Patients with PAD undergoing LER were enrolled into the multicenter, prospective Platelet Activity and Cardiovascular Events (PACE) study. Platelet aggregation was assessed by light transmission aggregometry (LTA) to submaximal epinephrine (0.4μ M) immediately prior to LER, and on post-operative day 1 or 2 (POD1) and 30 (POD30). A hyperreactive platelet phenotype was defined as >60% aggregation. Patients were followed longitudinally for MACLE, defined as the composite of death, myocardial infarction, stroke, major lower extremity amputation, or acute limb ischemia leading to reintervention. RESULTS Among 287 patients undergoing LER, mean age was 70 ± 11 years, 33% were female, 61% were white, and 89% were on baseline antiplatelet therapy. Platelet aggregation to submaximal epinephrine induced a bimodal response; 15.5%, 16.8%, and 16.4% of patients demonstrated a hyperreactive platelet phenotype at baseline, POD1, and POD30, respectively. Platelet aggregation increased by 18.5% (P=0.001) from baseline to POD1, which subsequently returned to baseline at POD30. After a median follow-up of 19 months, MACLE occurred in 165 (57%) patients. After adjustment for demographics, clinical risk factors, procedure type, and antiplatelet therapy, platelet hyperreactivity at POD1 was associated with a significant hazard of long-term MACLE (aHR 4.61, 95% CI 2.08-10.20, P<0.001). CONCLUSION Among patients with severe PAD, platelet activity increases following LER. Platelet hyperreactivity to submaximal epinephrine on POD1 is associated with long-term MACLE. Platelet activity following LER may represent a modifiable biomarker associated with excess cardiovascular risk.

Impact of staged goal-directed fluid therapy on postoperative pulmonary complications in patients undergoing McKeown esophagectomy: a randomized controlled trial. BMC Anesthesiol 2024; 24:330. [PMID: 39289608 PMCID: PMC11406780 DOI: 10.1186/s12871-024-02719-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Accepted: 09/06/2024] [Indexed: 09/19/2024] Open
Abstract
BACKGROUND Our aim was to evaluate the influence of staged goal directed therapy (GDT) on postoperative pulmonary complications (PPCs), intraoperative hemodynamics and oxygenation in patients undergoing Mckeown esophagectomy. METHODS Patients were randomly divided into three groups, staged GDT group (group A, n = 56): stroke volume variation (SVV) was set at 8-10% during the one lung ventilation (OLV) stage and 8-12% during the two lung ventilation (TLV) stage, GDT group (group B, n = 56): received GDT with a target SVV of 8-12% During the entire surgical procedure, and control group (group C, n = 56): conventional fluid therapy was administered by mean arterial pressure (MAP), central venous pressure (CVP), and urine volume. The primary outcome was the incidence of postoperative pulmonary complications within Postoperative days (POD) 7. The secondary outcomes were postoperative lung ultrasound (LUS) B-lines artefacts (BLA) scoring, incidence of other complications, the length of hospital stay, intraoperative hemodynamic and oxygenation indicators included mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), cardiac output (CO), oxygenation index (OI), respiratory indices (RI), alveolar-arterial oxygen difference (Aa-DO2). RESULTS Patients in group A and group B had a lower incidence of PPCs (7/56 vs. 17/56 and 9/56 vs. 17/56, p < 0.05), and a fewer B-lines score on postoperative ultrasound (4.61 ± 0.51 vs. 6.15 ± 0.74 and 4.75 ± 0.62 vs. 6.15 ± 0.74, p < 0.05) compared to group C. The CI, CO, MAP, and OI were higher in group A compared to group B and group C in the stage of thoracic operation. During the abdominal operation stage, patients in group A and group B had a better hemodynamic and oxygenation indicators than group C. CONCLUSIONS In comparison to conventional fluid therapy, intraoperative staged GDT can significantly reduce the incidence of postoperative pulmonary complications in patients undergoing McKeown esophagectomy, facilitating patient recovery. Compared to GDT, it can improve intraoperative oxygenation and stabilize intraoperative hemodynamics in patients. TRIAL REGISTRATION This study was registered in the Chinese Clinical Trial Registry on 24/11/2021 (ChiCTR2100053598).

Abstract
BACKGROUND Gallbladder cancer (GBC) is associated with a high mortality rate. Asian American (AsA) are among the fastest-growing populations in the United States, yet little is known about the disparity of GBC within this cohort. This study identified trends in treatment and outcomes for GBC in a disaggregated fashion, specifically for this population. METHODS A retrospective analysis of the National Cancer Database (NCDB) between 2010 and 2019 examining all patients treated for gallbladder cancer was performed. Basic demographic factors were identified for patients of Caucasian, African American, and disaggregated Asian subpopulations. Survival curves were used to identify differences in median overall survival, and a multivariate analysis was performed to determine which factors impact overall survival. RESULTS A total of 1317 (5%) patients were of AsA origin. Median survival for the overall AsA population is 15.1 months compared with Caucasian (11.5 months) and African Americans (11.4 months) (p < 0.0001). Within the AsA groups, the Korean subpopulation had the lowest survival at 12.6 months, whereas Filipinos had the longest survival at 19.1 months (p < 0.0001). Patients of Filipino descent had the highest rate of surgical resection but lower chemotherapy utilization. Conversely, Korean patients had the highest utilization of multimodality therapy. Multivariate analysis demonstrated that belonging to Chinese, Filipino, or Indian ethnicity was associated with decreased risk of mortality. CONCLUSIONS There are disparate differences in survival for patients with GBC between AsA groups. Socioeconomic, genetic, and epigenetic factors may influence these differences. Further research is needed to delineate the causes of this disparity.

A qualitative study of providers' perspectives on cross-institutional care coordination for pancreatic cancer: challenges and opportunities. BMC Health Serv Res 2024; 24:1041. [PMID: 39251999 PMCID: PMC11382481 DOI: 10.1186/s12913-024-11483-1] [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: 04/23/2023] [Accepted: 08/22/2024] [Indexed: 09/11/2024] Open
Abstract
BACKGROUND Despite calls for regionalizing pancreatic cancer (PC) care to high-volume centers (HVCs), many patients with PC elect to receive therapy closer to their home or at multiple institutions. In the context of cross-institutional PC care, the challenges associated with coordinating care are poorly understood. METHODS In this qualitative study we conducted semi-structured interviews with oncology clinicians from a HVC (n = 9) and community-based hospitals (n = 11) to assess their perspectives related to coordinating the care of and treating PC patients across their respective institutions. Interviews were transcribed, coded, and analyzed using deductive and inductive approaches to identify themes related to cross-institutional coordination challenges and to note improvement opportunities. RESULTS Clinicians identified challenges associated with closed-loop communication due, in part, to not having access to a shared electronic health record. Challenges with patient co-management were attributed to patients receiving inconsistent recommendations from different clinicians. To address these challenges, participants suggested several improvement opportunities such as building rapport with clinicians across institutions and updating tumor board processes. The opportunity to update tumor board processes was reportedly multi-dimensional and could involve: (1) designating a tumor board coordinator; (2) documenting and disseminating tumor board recommendations; and (3) using teleconferencing to facilitate community-based clinician engagement during tumor board meetings. CONCLUSIONS In light of communication barriers and challenges associated with patient co-management, enabling the development of relationships among PC clinicians and improving the practices of multidisciplinary tumor boards could potentially foster cross-institutional coordination. Research examining how multidisciplinary tumor board coordinators and teleconferencing platforms could enhance cross-institutional communication and thereby improve patient outcomes is warranted.

Outcome-Orientated Organ Allocation-A Composite Risk Model for Pancreas Graft Evaluation and Acceptance. J Clin Med 2024; 13:5177. [PMID: 39274392 PMCID: PMC11396207 DOI: 10.3390/jcm13175177] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 08/25/2024] [Accepted: 08/29/2024] [Indexed: 09/16/2024] Open
Abstract
Background: Pancreas transplantation (PTX) remains the most effective treatment to prevent long-term complications and provide consistent euglycemia in patients with endocrine pancreatic insufficiency, mainly in type I diabetic patients. Considering early graft loss (EGL) and the perioperative complication rate, an optimal risk stratification based on donor risk factors is paramount. Methods: In our single-center study, we retrospectively assessed the risk factors for EGL and reduced graft survival in 97 PTXs (82 simultaneous pancreas and kidney [SPK], 11 pancreases transplanted after kidney [PAK] and 4 pancreases transplanted alone [PTA]) between 2010 and 2021. By statistically analyzing the incorporation of different donor risk factors using the Kaplan-Meier method and a log-rank test, we introduced a composite risk model for the evaluation of offered pancreas grafts. Results: The overall EGL rate was 6.5%. In the univariate analysis of donor characteristics, age > 45 years, BMI > 25 kg/m2, lipase > 60 U/L, cerebrovascular accident (CVA) as the cause of death, mechanical cardiopulmonary resuscitation (mCPR), cold ischemia time (CIT) > 600 min and retrieval by another center were identified as potential risk factors; however, they lacked statistical significance. In a multivariate model, age > 45 years (HR 2.05, p = 0.355), BMI > 25 kg/m2 (HR 3.18, p = 0.051), lipase > 60 U/L (HR 2.32, p = 0.148), mCPR (HR 8.62, p < 0.0001) and CIT > 600 min (HR 1.89, p = 0.142) had the greatest impact on pancreas graft survival. We subsumed these factors in a composite risk model. The combination of three risk factors increased the rate of EGL significantly (p = 0.003). Comparing the pancreas graft survival curves for ≥3 risk factors to <3 risk factors in a Kaplan-Meier model revealed significant inferiority in the pancreas graft survival rate (p = 0.029). Conclusions: When evaluating a potential donor organ, grafts with a combination of three or more risk factors should only be accepted after careful consideration to reduce the risk of EGL and to significantly improve outcomes after PTX.

Abstract
BACKGROUND Stanford Type A Aortic Dissection (TAAD) is associated with high in-hospital mortality and the need for immediate surgical intervention. Larger hospital size may be associated with better patient care and surgical outcomes. This study aimed to examine the effect of hospital size on TAAD outcomes. METHOD Patients who underwent TAAD repair were identified in National Inpatient Sample (NIS) from Q4 2015-2020. NIS stratifies hospital size into small, medium, and large based on the number of hospital beds, geographical location, and the teaching status of the hospitals. Patients admitted to small/medium and large hospitals were stratified into two cohorts. Multivariable logistic regressions were performed to compare in-hospital outcomes, adjusted for demographics, comorbidity, primary payer status, and hospital characteristics including procedural volume. RESULTS There were 1106 and 3752 TAAD admitted to small/medium and large hospitals, respectively. Among patients admitted to small/medium hospitals, there was higher mortality (17.27% vs 14.37%, aOR = 1.32, P < 0.01), but shorter length of stay (P < 0.01) and lower cost (P = 0.03) compared to larger hospitals. There was no difference in morbidities. CONCLUSIONS Marked higher mortality is associated with admission to smaller hospitals among patients with TAAD, which may in turn decrease the average hospital stay and cost. Given that a significant percentage of patients are already being transferred out of the initial hospital and small/medium hospital is associated with higher mortality, centralization of care in centers of excellence may decrease the high mortality associated with TAAD.

[PMID: 39153890 DOI: 10.1016/j.urolonc.2024.06.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 06/03/2024] [Accepted: 06/10/2024] [Indexed: 08/19/2024]
Abstract
INTRODUCTION AND OBJECTIVES Radical cystectomy readmission rates remain high, with around 25% of patients readmitted to index and nonindex hospitals in 30 days. Nonindex readmissions have been associated with poorer outcomes, including longer lengths of stay and higher mortality rates. This study aimed to examine the associations of social factors (e.g., sex, race, socioeconomic status, insurance type, and resident location) on readmission to index versus nonindex hospitals and discharge disposition. METHODS We conducted a population-based retrospective study using the Pennsylvania Cancer Registry (PCR) to identify patients diagnosed with nonmetastatic muscle-invasive bladder cancer who underwent radical cystectomy in Pennsylvania between 2010 and 2018. Readmitted patients were identified using the Pennsylvania Health Care Cost Containment Council data (PHC4). The primary outcome was readmission location (i.e., index or nonindex hospital) following radical cystectomy. We used chi-square tests for categorical variables, Wilcoxon rank sum test for continuous variables, multivariable logistic regression model to assess predictors of being readmitted to an index hospital and calculating the predicted probability of being admitted to an index hospital depending on discharge disposition. RESULTS A total of 517 patients were readmitted within 30-days after radical cystectomy. The majority of readmissions were index readmissions (83%). Median readmission hospital stay was 4 days (interquartile range [IQR] 4) for index and 5 days (IQR 7) for nonindex hospitals, P = 0.01. Patients readmitted to index hospitals had fewer comorbidities (median weighted Elixhauser Comorbidity Index 2 (IQR 2)) and lived in urban areas (89%). Discharge with home care was associated with a higher odds of index readmission (odds ratio, [OR] 2.40; 95% confidence interval, [CI] 1.25-4.52). CONCLUSIONS Patients residing in urban areas and with fewer comorbidities were more likely to be readmitted to index hospitals than nonindex hospitals. Socioeconomic status and insurance type did not correlate with the type of readmission. Finally, being discharged with home health care was found to be a predictor of readmission to an index hospital.

Comparison of Hospital Volume and Risk-Standardized Mortality Rate as a Proxy for Hospital Quality in Complex Oncologic Hepatopancreatobiliary Surgery. Ann Surg Oncol 2024; 31:4922-4930. [PMID: 38700800 PMCID: PMC11236847 DOI: 10.1245/s10434-024-15361-2] [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: 02/27/2024] [Accepted: 04/09/2024] [Indexed: 07/13/2024]
Abstract
BACKGROUND Centralization of hepatopancreatobiliary procedures to more experienced centers has been recommended but remains controversial. Hospital volume and risk-stratified mortality rates (RSMR) are metrics for interhospital comparison. We compared facility operative volume with facility RSMR as a proxy for hospital quality. PATIENTS AND METHODS Patients who underwent surgery for liver (LC), biliary tract (BTC), and pancreatic (PDAC) cancer were identified in the National Cancer Database (2004-2018). Hierarchical logistic regression was used to create facility-specific models for RSMR. Volume (high versus low) was determined by quintile. Performance (high versus low) was determined by RSMR tercile. Primary outcomes included median facility RSMR and RSMR distributions. Volume- and RSMR-based redistribution was simulated and compared for reductions in 90-day mortality. RESULTS A total of 106,217 patients treated at 1282 facilities were included; 17,695 had LC, 23,075 had BTC, and 65,447 had PDAC. High-volume centers (HVC) had lower RSMR compared with medium-volume centers and low-volume centers for LC, BTC, and PDAC (all p < 0.001). High-performance centers (HPC) had lower RSMR compared with medium-performance centers and low-performance centers for LC, BTC, and PDAC (all p < 0.001). Volume-based redistribution required 16.0 patients for LC, 11.2 for BTC, and 14.9 for PDAC reassigned to 15, 22, and 20 centers, respectively, per life saved within each US census region. RSMR-based redistribution required 4.7 patients for LC, 4.2 for BTC, and 4.9 for PDAC reassigned to 316, 403, and 418 centers, respectively, per life saved within each US census region. CONCLUSIONS HVC and HPC have the lowest overall and risk-standardized 90-day mortality after oncologic hepatopancreatobiliary procedures, but RSMR may outperform volume as a measure of hospital quality.

Abstract
Pancreatoduodenectomy is the most appropriate technique for the treatment of periampullary tumors. In the past, this procedure was associated with high mortality and morbidity, but with improvements in patient selection, anesthesia, and surgical technique, mortality has decreased to less than 5%. However, morbidity remains increased due to various complications such as delayed gastric emptying, bleeding, abdominal collections, and abscesses, most of which are related to the pancreatojejunostomy leak. Clinically relevant postoperative pancreatic fistula is the most dangerous and is related to other complications including mortality. The incidence of postoperative pancreatic fistula ranges from 5-30%. Various techniques have been developed to reduce the severity of pancreatic fistulas, from the use of an isolated jejunal loop for pancreatojejunostomy to binding and invagination anastomoses. Even total pancreatectomy has been considered to avoid pancreatic fistula, but the late effects of this procedure are unacceptable, especially in relatively young patients. Recent studies on the main techniques of pancreatojejunostomy concluded that duct-to-mucosa anastomosis is advisable, but no technique eliminates the risk of pancreatic fistula. The purpose of this study is to highlight technical details and tips that may reduce the severity of pancreatic fistula after pancreatojejunostomy during open or minimally invasive pancreatoduodenectomy.

Abstract
BACKGROUND Textbook oncologic outcome (TOO) serves as a composite, oncologic metric for surgical quality of care. We sought to evaluate variations in TOO among patients undergoing laparoscopic, robotic, and open surgery for intrahepatic (iCCA) and perihilar (pCCA) cholangiocarcinoma. METHODS Patients who underwent liver resection for iCCA and pCCA between 2010 and 2018 were identified from the National Cancer Database. Entropy balancing was performed for covariate balancing and multivariable regression was used to evaluate the association between surgical approach and TOO. RESULTS Among 5434 patients who underwent hepatic resection between 2010 and 2018, 3888 (71.6%) had iCCA, and 1546 (28.4%) had pCCA. TOO was achieved in 11.7% (n = 454), and 18.8% (n = 291) of patients with iCCA and pCCA, respectively. There was a difference in achievement of TOO relative to operative approach among patients with iCCA (robotic: 6.2% vs. laparoscopic: 8.1% vs. open: 12.5%; p = 0.002). After entropy balancing, patients with iCCA undergoing laparoscopic surgery had 32% reduced odds of achieving TOO (Ref: open surgery; laparoscopic, OR 0.68, 95%CI 0.49-0.93; p = 0.016; robotic, OR 0.69, 95%CI 0.34-1.39; p = 0.298). CONCLUSIONS Usage of composite oncologic measures such as TOO may allow for a holistic assessment of different approaches to hepatic resection among patients with CCA.

Abstract
OBJECTIVE The purpose of this study was to statistically analyze the factors that influence cardiovascular surgery recruitment. METHODS Fifth- and sixth-year medical students and first-year residents who participated in cardiovascular surgery-related events at our university over a 10-year period from April 2013 to August 2022 were included. The primary endpoint was admission to the department of cardiovascular surgery. Gender, participation in sixth-year elective clinical training, participation in national academic conferences, participation in cardiovascular surgery summer school, and the cost of participation in these events (airfares and lodging) were included as analytic factors. RESULTS Fifty-three participants attended cardiovascular surgery events during the study period. The sample included 48 males (84%) and 9 females (16%), and 3 fifth-year medical students (5%), 45 sixth-year students (79%), and 9 students in their first year of clinical training (16%). Eighteen (32%) of the participants eventually joined the department. Gender, participation in national academic conferences, cardiovascular surgery summer school, and cost of participation were not significantly related to the decision to join the department, but participation in elective clinical training was significantly positively related to the decision to join the department for sixth-year students (p < 0.01). CONCLUSIONS We statistically analyzed the factors involved in the recruitment of students and initial clinical residents to the department of cardiovascular surgery. The results showed that participation in elective clinical training was significantly positively associated with the decision to join the department, suggesting that efforts to encourage participation in elective clinical training are important.

Abstract
INTRODUCTION This study aims to assess the association of operative time with the postoperative length of stay and unplanned return to the operating room in patients undergoing femoral to below knee popliteal bypasses, stratified by autologous vein graft or polytetrafluoroethylene (PTFE). MATERIALS AND METHODS A retrospective analysis of vascular quality initiative database (2003-2021). The selected patients were grouped into the following: vein bypass (group I) and PTFE (group II) patients. Each group was further stratified by a median split of operative time (i.e., 210 min for autologous vein and 155 min for PTFE) to study the outcomes. The outcomes were assessed by univariate and multivariate approach. RESULTS Of the 10,902 patients studied, 3570 (32.7%) were in the autologous vein group, while 7332 (67.3%) were in the PTFE group. Univariate analysis revealed autologous vein and PTFE graft recipients that had increased operative times were associated with a longer mean postoperative length of stay and a higher incidence of all-cause return to the operating room. In PTFE group, patients with prolonged operative times were also found to be associated with higher incidence of major amputation, surgical site infection, and cardiovascular events, along with loss of primary patency within a year. CONCLUSIONS For patients undergoing femoral to below knee popliteal bypasses using an autologous vein or PTFE, longer operative times were associated with inferior outcomes. Mortality was not found to be associated with prolonged operative time.

Abstract
INTRODUCTION Due to the high morbidity associated with esophagectomies, patients are often directly admitted to intensive care units (ICUs) for postoperative monitoring. However, critical complications can arise after this initial ICU stay. We hypothesized that the timing of ICU stay was not optimal for the care of patients after esophagectomy and aimed to determine when patients are at risk for developing critical complications. METHODS We searched the National Safety and Quality Improvement Program for patients who underwent an esophagectomy between 2016 and 2021. The outcome of interest was the interval between surgery and first critical complication. A critical complication was defined as one likely to require intensive care, including respiratory failure, septic shock, etc. Multivariate regression was performed to identify the risks of complications. RESULTS This study included 6813 patients from more than 70 institutions. Within the first 30 d postesophagectomy, 21.59% of patients experienced at least one critical complication. Half of first critical complications occurred after postoperative day 5, and 85.05% of them occurred after postoperative day 2. Risk factors for critical complications included age greater than 60 y, preoperative comorbidities, and open surgical approach. Malignancies were associated with a significantly lower incidence of critical complications. CONCLUSIONS Critical complications occurred beyond the immediate postesophagectomy period. Therefore, low-risk patients undergoing minimally invasive esophagectomies can be safely monitored outside the ICU, allowing for better patient care and resource utilization.

Abstract
OBJECTIVES Currently, there remains debate regarding the optimal anesthesia approach for patients undergoing intra-arterial therapy for acute ischemic stroke. Therefore, we conducted a comparative analysis to assess the effects of general anesthesia versus non general anesthesia on patient outcomes. METHODS The research methodology entailed comprehensive searches of prominent databases such as the Cochrane Library, PubMed, Scopus, and Web of Science, covering the period from January 1, 2010, to March 1, 2024. Data synthesis employed techniques like risk ratio or standardized mean difference, along with 95% confidence intervals. The study protocol was prospectively registered with PROSPERO (CRD42024523079). RESULTS A total of 27 trials and 12,875 patients were included in this study. The findings indicated that opting for non-general anesthesia significantly decreased the risk of in-hospital mortality (RR, 1.98; 95% CI: 1.50 to 2.61; p<0.00001; I2 = 20%), as well as mortality within three months post-procedure (RR, 1.24; 95% CI: 1.15 to 1.34; p<0.00001; I2 = 26%), while also leading to a shorter hospitalization duration (SMD, 0.24; 95% CI: 0.15 to 0.33; p<0.00001; I2 = 44%). CONCLUSION Ischemic stroke patients who undergo intra-arterial treatment without general anesthesia have a lower risk of postoperative adverse events and less short-term neurological damage. In routine and non-emergency situations, non-general anesthetic options may be more suitable for intra-arterial treatment, offering greater benefits to patients. In addition to this, the neuroprotective effects of anesthetic drugs should be considered more preoperatively and postoperatively.

Abstract
Background/Aims : Recently, patients with pancreatic cancer (PC) who underwent resection have exhibited improved survival outcomes, but comprehensive analysis is limited. We analyzed the trends of contributing factors. Methods : Data of patients with resected PC were retrospectively collected from the Korean Health Insurance Review and Assessment Service (HIRA) database and separately at our institution. Cox regression analysis was conducted with the data from our institution a survival prediction score was calculated using the β coefficients. Results : Comparison between the periods 2013-2015 (n=3,255) and 2016-2018 (n=3,698) revealed a difference in the median overall survival (25.9 months vs not reached, p<0.001) when analyzed with the HIRA database which was similar to our single-center data (2013-2015 [n=119] vs 2016-2018 [n=148], 20.9 months vs 32.2 months, p=0.003). Multivariable analyses revealed six factors significantly associated with better OS, and the scores were as follows: age >70 years, 1; elevated carbohydrate antigen 19-9 at diagnosis, 1; R1 resection, 1; stage N1 and N2, 1 and 3, respectively; no adjuvant treatment, 2; FOLFIRINOX or gemcitabine plus nab-paclitaxel after recurrence, 4; and other chemotherapy or supportive care only after recurrence, 5. The rate of R0 resection (69.7% vs 80.4%), use of adjuvant treatment (63.0% vs 74.3%), and utilization of FOLFIRINOX or gemcitabine plus nab-paclitaxel (25.2% vs 47.3%) as palliative chemotherapeutic regimen, all increased between the two time periods, resulting in decreased total survival prediction score (mean: 7.32 vs 6.18, p=0.004). Conclusions : Strict selection of surgical candidates, more use of adjuvant treatment, and adoption of the latest combination regimens for palliative chemotherapy after recurrence were identified as factors of recent improvement.

BACKGROUND Esophagectomy is associated with significant mortality. A better understanding of the causes leading to death may help to reduce mortality. A root cause analysis of mortality after esophagectomy was performed. METHODS Root cause analysis was retrospectively applied by an independent expert panel of 4 upper gastrointestinal surgeons and 1 anesthesiologist-intensivist to patients included in the French national multicenter prospective cohort FREGAT between August 2014 and September 2019 who underwent an esophagectomy for cancer and died within 90 days of surgery. A cause-and-effect diagram was used to determine the root causes related to death. Death was classified as potentially preventable or non-preventable. RESULTS Among the 1,040 patients included in the FREGAT cohort, 70 (6.7%) patients (male: 81%, median age 68 [62-72] years) from 17 centers were included. Death was potentially preventable in 37 patients (53%). Root causes independently associated with preventable death were inappropriate indication (odds ratio 35.16 [2.50-494.39]; P = .008), patient characteristics (odds ratio 5.15 [1.19-22.35]; P = .029), unexpected intraoperative findings (odds ratio 18.99 [1.07-335.55]; P = .045), and delay in diagnosis of a complication (odds ratio 98.10 [6.24-1,541.04]; P = .001). Delay in treatment of a complication was found only in preventable deaths (28 [76%] vs 0; P < .001). National guidelines were less frequently followed (16 [43%] vs 22 [67%]; P = .050) in preventable deaths. The only independent risk factor of preventable death was center volume <26 esophagectomies per year (odds ratio 4.71 [1.55-14.33]; P = .006). CONCLUSIONS More than one-half of deaths after esophagectomy were potentially preventable. Better patient selection, early diagnosis, and adequate management of complications through centralization could reduce mortality.

Surgeon volume and outcomes following thoracic endovascular aortic repair for blunt thoracic aortic injury. J Vasc Surg 2024; 80:53-63.e3. [PMID: 38431064 DOI: 10.1016/j.jvs.2024.02.032] [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: 12/12/2023] [Revised: 02/10/2024] [Accepted: 02/26/2024] [Indexed: 03/05/2024]
Abstract
OBJECTIVE Thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) at high-volume hospitals has previously been associated with lower perioperative mortality, but the impact of annual surgeon volume on outcomes following TEVAR for BTAI remains unknown. METHODS We analyzed Vascular Quality Initiative (VQI) data from patients with BTAI that underwent TEVAR between 2013 and 2023. Annual surgeon volumes were computed as the number of TEVARs (for any pathology) performed over a 1-year period preceding each procedure and were further categorized into quintiles. Surgeons in the first volume quintile were categorized as low volume (LV), the highest quintile as high volume (HV), and the middle three quintiles as medium volume (MV). TEVAR procedures performed by surgeons with less than 1-year enrollment in the VQI were excluded. Using multilevel logistic regression models, we evaluated associations between surgeon volume and perioperative outcomes, accounting for annual center volumes and adjusting for potential confounders, including aortic injury grade and severity of coexisting injuries. Multilevel models accounted for the nested clustering of patients and surgeons within the same center. Sensitivity analysis excluding patients with grade IV BTAI was performed. RESULTS We studied 1321 patients who underwent TEVAR for BTAI (28% by LV surgeons [0-1 procedures per year], 52% by MV surgeons [2-8 procedures per year], 20% by HV surgeons [≥9 procedures per year]). With higher surgeon volume, TEVAR was delayed more (in <4 hours: LV: 68%, MV: 54%, HV: 46%; P < .001; elective (>24 hours): LV: 5.1%; MV: 8.9%: HV: 14%), heparin administered more (LV: 80%, MV: 81%, HV: 87%; P = .007), perioperative mortality appears lower (LV: 11%, MV: 7.3%, HV: 6.5%; P = .095), and ischemic/hemorrhagic stroke was lower (LV: 6.5%, MV: 3.6%, HV: 1.5%; P = .006). After adjustment, compared with LV surgeons, higher volume surgeons had lower odds of perioperative mortality (MV: 0.49; 95% confidence interval [CI], 0.25-0.97; P = .039; HV: 0.45; 95% CI, 0.16-1.22; P = .12; MV/HV: 0.50; 95% CI, 0.26-0.96; P = .038) and ischemic/hemorrhagic stroke (MV: 0.38; 95% CI, 0.18-0.81; P = .011; HV: 0.16; 95% CI, 0.04-0.61; P = .008). Sensitivity analysis found lower adjusted odds for perioperative mortality (although not significant) and ischemic/hemorrhagic stroke for higher volume surgeons. CONCLUSIONS In patients undergoing TEVAR for BTAI, higher surgeon volume is independently associated with lower perioperative mortality and postoperative stroke, regardless of hospital volume. Future studies could elucidate if TEVAR for non-ruptured BTAI might be delayed and allow stabilization, heparinization, and involvement of a higher TEVAR volume surgeon.

Association of hospital volume and operative approach with clinical and financial outcomes of elective esophagectomy in the United States. PLoS One 2024; 19:e0303586. [PMID: 38875301 PMCID: PMC11178205 DOI: 10.1371/journal.pone.0303586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Accepted: 04/16/2024] [Indexed: 06/16/2024] Open
Abstract
INTRODUCTION Literature regarding the impact of esophagectomy approach on hospitalizations costs and short-term outcomes is limited. Moreover, few have examined how institutional MIS experience affects costs. We thus examined utilization trends, costs, and short-term outcomes of open and minimally invasive (MIS) esophagectomy as well as assessing the relationship between institutional MIS volume and hospitalization costs. METHODS All adults undergoing elective esophagectomy were identified from the 2016-2020 Nationwide Readmissions Database. Multiple regression models were used to assess approach with costs, in-hospital mortality, and major complications. Additionally, annual hospital MIS esophagectomy volume was modeled as a restricted cubic spline against costs. Institutions performing > 16 cases/year corresponding with the inflection point were categorized as high-volume hospitals (HVH). We subsequently examined the association of HVH status with costs, in-hospital mortality, and major complications in patients undergoing minimally invasive esophagectomy. RESULTS Of an estimated 29,116 patients meeting inclusion, 10,876 (37.4%) underwent MIS esophagectomy. MIS approaches were associated with $10,600 in increased incremental costs (95% CI 8,800-12,500), but lower odds of in-hospital mortality (AOR 0.76; 95% CI 0.61-0.96) or major complications (AOR 0.68; 95% CI 0.60, 0.77). Moreover, HVH status was associated with decreased adjusted costs, as well as lower odds of postoperative complications for patients undergoing MIS operations. CONCLUSION In this nationwide study, MIS esophagectomy was associated with increased hospitalization costs, but improved short-term outcomes. In MIS operations, cost differences were mitigated by volume, as HVH status was linked with decreased costs in the setting of decreased odds of complications. Centralization of care to HVH centers should be considered as MIS approaches are increasingly utilized.

Abstract
Pancreatic and periampullary cancers pose significant challenges in oncological care due to their complexity and diagnostic difficulties. Global experiences underscore the crucial role of multidisciplinary collaboration and centralized care in improving patient outcomes in this context. Recognizing these challenges, Lombardy, Italy's most populous region, embarked on establishing pancreas units across its territory to enhance clinical outcomes and organizational efficiency. This initiative, driven by a multistakeholder approach involving the Lombardy Welfare Directorate, clinicians, and a patient association, emphasizes the centralization of complex care in high-volume hospitals, adopting a hub-and-spoke model and a multidisciplinary approach. This article outlines the process and criteria set forth for pancreas unit implementation, aiming to provide a structured framework for enhancing pancreatic cancer care. Central to this initiative is the establishment of structured criteria and minimal requirements, not only for surgery but also for other essential components of care, ensuring a comprehensive approach to pancreatic cancer management. The Lombardy model offers a structured framework for enhancing pancreatic cancer care, with potential applicability to other regions and countries seeking to improve their cancer care infrastructure.

Abstract
OBJECTIVE To analyze the association of a surgeon's experience with postoperative outcomes of pancreatoduodenectomies (PDs) when stratified by Fistula Risk Score (FRS). BACKGROUND Centralization is now well-established for pancreatic surgery. Nevertheless, the benefits of individual surgeon's experience in high-volume settings remain undefined. METHODS Pancreatoduodenectomies performed by 82 surgeons across 18 international specialty institutions (median: 140 PD/year) were analyzed. Surgeon cumulative PD volume was linked with postoperative outcomes through multivariable models, adjusted for patient/operative characteristics and the FRS. Then, surgeon experience was also stratified by the 10, previously defined, most clinically impactful scenarios for clinically relevant pancreatic fistula (CR-POPF) development. RESULTS Of 8189 PDs, 18.7% suffered severe complications (Accordion≥3), 4.8% were reoperated upon and 2.2% expired. Although the most experienced surgeons (top-quartile; >525 career PDs) more often operated on riskier cases, their experience was significantly associated with declines in CR-POPF ( P <0.001), severe complications ( P =0.008), reoperations ( P <0.001), and length of stay (LOS) ( P <0.001)-accentuated even more in the most impactful FRS scenarios (2830 patients). Risk-adjusted models indicate male sex, increasing age, ASA class, and FRS, but not surgeon experience, as being associated with severe complications, failure-to-rescue, and mortality. Instead, upper-echelon experience demonstrates significant reductions in CR-POPF (OR 0.66), reoperations (OR 0.64), and LOS (OR 0.65) in moderate-to-high fistula risk circumstances (FRS≥3, 68% of cases). CONCLUSIONS At specialty institutions, major morbidity, mortality, and failure-to-rescue are primarily associated with baseline patient characteristics, while cumulative surgical experience impacts pancreatic fistula occurrence and its attendant effects for most higher-risk pancreatoduodenectomies. These data also suggest an extended proficiency curve exists for this operation.

Abstract
BACKGROUND The magnitude of the risk of death and cardiac arrest associated with emergency surgery and anesthesia is not well understood. Our aim was to assess whether the risk of perioperative and anesthesia-related death and cardiac arrest has decreased over the years, and whether the rates of decrease are consistent between developed and developing countries. METHODS A systematic review was performed using electronic databases to identify studies in which patients underwent emergency surgery with rates of perioperative mortality, 30-day postoperative mortality, or perioperative cardiac arrest. Meta-regression and proportional meta-analysis with 95% confidence intervals (CIs) were performed to evaluate global data on the above three indicators over time and according to country Human Development Index (HDI), and to compare these results according to country HDI status (low vs. high HDI) and time period (pre-2000s vs. post-2000s). RESULTS 35 studies met the inclusion criteria, representing more than 3.09 million anesthetic administrations to patients undergoing anesthesia for emergency surgery. Meta-regression showed a significant association between the risk of perioperative mortality and time (slope: -0.0421, 95%CI: from - 0.0685 to -0.0157; P = 0.0018). Perioperative mortality decreased over time from 227 per 10,000 (95% CI 134-380) before the 2000s to 46 (16-132) in the 2000-2020 s (p < 0-0001), but not with increasing HDI. 30-day postoperative mortality did not change significantly (346 [95% CI: 303-395] before the 2000s to 292 [95% CI: 201-423] in the 2000s-2020 period, P = 0.36) and did not decrease with increasing HDI status. Perioperative cardiac arrest rates decreased over time, from 113 per 10,000 (95% CI: 31-409) before the 2000s to 31 (14-70) in the 2000-2020 s, and also with increasing HDI (68 [95% CI: 29-160] in the low-HDI group to 21 [95% CI: 6-76] in the high-HDI group, P = 0.012). CONCLUSIONS Despite increasing baseline patient risk, perioperative mortality has decreased significantly over the past decades, but 30-day postoperative mortality has not. A global priority should be to increase long-term survival in both developed and developing countries and to reduce overall perioperative cardiac arrest through evidence-based best practice in developing countries.

Abstract
PURPOSE Patients undergoing oncologic surgery at major referral centers frequently experience postdischarge care fragmentation, which has been associated with poor outcomes. This report describes and evaluates the outcomes of an intervention at Memorial Sloan Kettering Cancer Center (MSKCC) to decentralize postdischarge postoperative acute care within our health care system. METHODS In 2018, MSKCC completed the addition of six regional acute care clinics called symptom care clinics (SCCs) to existing regional outpatient clinics. Acute care was previously only available within our system at a single centralized urgent care center (UCC). All patients undergoing surgery in our system between January 1, 2019, and June 30, 2021, were followed for 90 days. The exposure was the site of initial acute care presentation-UCC or SCC-and outcomes included utilization, access, financial toxicity, and mortality. Mortality was adjusted using hierarchical modeling at the level of the region. RESULTS A total of 6,992 postsurgical patients experienced 10,525 acute care visits in our system within 90 days of surgery. Twenty-nine percent of these patients presented to the SCC first. These patients were older but had fewer comorbidities and shorter index length of stay compared with UCC patients. Utilization of SCCs increased substantially while UCC utilization decreased during a period of stable case volume. SCCs were closer to patients' homes, and wait times were shorter. Rates of financial toxicity were similar between groups. Of this high-risk cohort accessing acute care postoperatively, 90-day mortality was similar for UCC and SCC patients (P = .731). CONCLUSION This model of decentralized acute care after oncologic surgery was increasingly used over time with comparable patient safety. Health systems should emphasize patient-centered care by supporting safe strategies for regionalized care even when treatments are delivered at centralized referral centers.

Abstract
INTRODUCTION We sought to define the individual contributions of patient characteristics (PCs), hospital characteristics (HCs), case volume (CV), and social determinants of health (SDoH) on in-hospital mortality (IHM) after complex cancer surgery. METHODS The California Department of Health Care Access and Information database identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PD), or proctectomy (PR) for a malignant diagnosis between 2010 and 2020. Multi-level multivariable regression was performed to assess the proportion of variance explained by PCs, HCs, CV and SDoH on IHM. RESULTS A total of 52,838 patients underwent cancer surgery (ES: n = 2,700, 5.1%; PN: n = 30,822, 58.3%; PD: n = 7530, 14.3%; PR: n = 11,786, 22.3%) across 294 hospitals. The IHM for the overall cohort was 1.7% and varied from 4.4% for ES to 0.8% for PR. On multivariable regression, PCs contributed the most to the variance in IHM (overall: 32.0%; ES: 21.6%; PN: 28.0%; PD: 20.3%; PR: 39.9%). Among the overall cohort, CV contributed 2.4%, HCs contributed 1.3%, and SDoH contributed 1.2% to the variation in IHM. CV was the second highest contributor to IHM among ES (5.3%), PN (5.3%), and PD (5.9%); however, HCs were a more important contributor among patients who underwent PR (8.0%). The unexplained variance in IHM was highest among ES (72.4%), followed by the PD (67.5%) and PN (64.6%) patient groups. CONCLUSIONS PCs are the greatest underlying contributor to variations in IHM following cancer surgery. These data highlight the need to focus on optimizing patients and exploring unexplained sources of IHM to improve quality of surgical care.

[PMID: 38309029 DOI: 10.1016/j.ygyno.2024.01.005] [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: 06/29/2023] [Revised: 12/31/2023] [Accepted: 01/05/2024] [Indexed: 02/05/2024]
Abstract
OBJECTIVE To quantify the impact on short-term ovarian cancer survival associated with treatment at high-performing hospitals using the observed-to-expected ratio (O/E) for adherence to ovarian cancer treatment guidelines as a risk-adjusted measure of hospital quality care. METHODS This was a retrospective population-based study of stage I-IV invasive epithelial ovarian cancer reported to California Cancer Registry 1996-2017. A fit logistic regression model, risk-adjusted for patient and disease characteristics, was used to calculate O/E for each hospital stratified by hospital annual case volume. Cox proportional hazards model was used for survival analyses at 3, 6, 12, 24 months and stratified according to sociodemographic characteristics. RESULTS The study population included 35,725 subjects treated at 443 hospitals: Low-O/E - 26.4% of cases; Intermediate-O/E - 55.5% of cases; and High-O/E - 18.1% of cases. Overall median survival by hospital category was: High-O/E = 72.5 months (95% CI = 68.6-78.6 months), Intermediate-O/E = 68.6 months (95% CI = 65.9-71.6 months), Low-O/E = 47.0 months (95% CI = 44.2-49.2 months). Initial treatment at a High-O/E hospital (HR = 1.00) was a statistically significant and independent predictor of improved short-term survival compared to Low-O/E hospitals at 3 months (HR = 1.46, 95% CI = 1.29-1.65), 6 months (HR = 1.35, 95% CI = 1.22-1.50), 12 months (HR = 1.27, 95% CI = 1.17-1.38), and 24 months (HR = 1.19, 95% CI = 1.11-1.27). Significant and independent associations between improved sort-term survival and High/O/E care were observed for Whites, Hispanics, Asian/Pacific Islanders (A/PI), across SES strata, and among all payer categories. CONCLUSION Ovarian cancer care at a High-O/E hospital is an independent predictor of improved outcome and the survival advantage is disproportionately weighted toward the short-term time horizon following diagnosis.

Abstract
OBJECTIVES There are significant variations in both perioperative and long-term outcomes after lung cancer resection. While perioperative outcomes are often used as comparative measures of quality, they are unreliable, and their association with long-term outcomes remain unclear. In this context, we evaluated whether historical perioperative mortality after lung cancer resection is associated with 5-year survival. PATIENTS AND METHODS The National Cancer Database (NCDB) was queried to identify patients diagnosed with non-small cell lung cancer (NSCLC) in 2010-2016 who underwent surgical resection (n = 234200). Hospital-level reliability-adjusted 90-day mortality rate quartiles for 2010-2013 was used as the independent variable to analyze 5-year survival for patients diagnosed in 2014-2016 (n = 85396). RESULTS There were 85,396 patients in the 2014-2016 cohort across 1,086 hospitals. Overall observed 90-day mortality rate was 3.2% (SD 17.6%) with 2.6% (SD 16.0%) for the historically best performing quartile vs. 3.9% (SD 19.4%) for the worst performing quartile (p < 0.0001). Patients who underwent resection at hospitals with the best historical mortality rate had significantly better 5-year survival across all stages compared to those treated at hospitals in the worst performing quartile in multivariate Cox regression analysis (all stages - HR 1.21 [95% CI 1.15-1.26]; stage I - HR 1.19 [95% CI 1.12-1.25]; stage II - HR 1.20 [95% CI 1.09-1.32]; stage III - HR 1.36 [95% CI 1.20-1.54]) and Kaplan-Meier survival estimates (all stages - p < 0.0001, stage I - p < 0.0001; stage II - p = 0.0004; stage III - p < 0.0001). CONCLUSION With expanded lung cancer screening criteria and likely increase in early-stage detection, profiling performance is paramount to ensuring mortality benefits. We found that episodes surrounding surgical resection may be used to profile long-term outcomes that likely reflect quality across a broader context of care. Evaluating lung cancer care quality using perioperative outcomes may be useful in profiling provider performance and guiding value-based payment policies.

Abstract
Importance In surgical patients, it is well known that higher hospital procedure volume is associated with better outcomes. To our knowledge, this volume-outcome association has not been studied in ambulatory surgery centers (ASCs) in the US. Objective To determine if low-volume ASCs have a higher rate of revisits after surgery, particularly among patients with multimorbidity. Design, Setting, and Participants This matched case-control study used Medicare claims data and analyzed surgeries performed during 2018 and 2019 at ASCs. The study examined 2328 ASCs performing common ambulatory procedures and analyzed 4751 patients with a revisit within 7 days of surgery (defined to be either 1 of 4735 revisits or 1 of 16 deaths without a revisit). These cases were each closely matched to 5 control patients without revisits (23 755 controls). Data were analyzed from January 1, 2018, through December 31, 2019. Main Outcomes and Measures Seven-day revisit in patients (cases) compared with the matched patients without the outcome (controls) in ASCs with low volume (less than 50 procedures over 2 years) vs higher volume (50 or more procedures). Results Patients at a low-volume ASC had a higher odds of a 7-day revisit vs patients who had their surgery at a higher-volume ASC (odds ratio [OR], 1.21; 95% CI, 1.09-1.36; P = .001). The odds of revisit for patients with multimorbidity were higher at low-volume ASCs when compared with higher-volume ASCs (OR, 1.57; 95% CI, 1.27-1.94; P < .001). Among patients with multimorbidity in low-volume ASCs, for those who underwent orthopedic procedures, the odds of revisit were 84% higher (OR, 1.84; 95% CI, 1.36-2.50; P < .001) vs higher-volume centers, and for those who underwent general surgery or other procedures, the odds of revisit were 36% higher (OR, 1.36; 95% CI, 1.01-1.83; P = .05) vs a higher-volume center. The findings were not statistically significant for patients without multimorbidity. Conclusions and Relevance In this observational study, the surgical volume of an ASC was an important indicator of patient outcomes. Older patients with multimorbidity should discuss with their surgeon the optimal location of their care.

Abstract
INTRODUCTION Pancreatic surgery is technically challenging, with mortality rates at high-volume centers ranging from 0% to 5%. An inverse relationship between surgeon volume and perioperative mortality has been reported suggesting that patients benefit from experienced surgeons at high-volume centers. There is little published on the volume of pancreatic surgeries performed in military treatment facilities (MTF) and there is no centralization policy regarding pancreatic surgery. This study evaluates pancreatic procedures at MTFs. We hypothesize that a small group of MTFs perform most pancreatic procedures, including more complex pancreatic surgeries. METHODS This is a retrospective review of de-identified data from MHS Mart (M2) from 2014 to 2020. The database contains patient data from all Defense Health Agency treatment facilities. Variables collected include number and types of pancreatic procedures performed and patient demographics. The primary endpoint was the number and type of surgery for each MTF. RESULTS Twenty-six MTFs performed pancreatic surgeries from 2014 to 2020. There was a significant decrease in the number of cases from 2014 to 2020. Nine hospitals performed one surgery over eight years. The most common surgery was a distal pancreatectomy, followed by a pancreaticoduodenectomy. There was a decrease in the number of pancreaticoduodenectomies and distal pancreatectomies performed over this period. CONCLUSIONS Pancreatic surgery is being performed at few MTFs with a downward trajectory over time. Further studies would be needed to assess the impact on patient care regarding postoperative complications, barriers to timely patient care, and impact on readiness of military surgeons.

Abstract
Surgical decision making is complex and involves a combination of analytic, intuitive, and cognitive processes. Medicolegal, infrastructural, and financial factors may influence these processes depending on the context and setting, but to what extent can they influence surgical decision making in gynecologic oncology? This scoping review evaluates existing literature related to medicolegal, infrastructural, and financial aspects of gynecologic cancer surgery and their implications in surgical decision making. Our objective was to summarize the findings and limitations of published research, identify gaps in the literature, and make recommendations for future research to inform policy.

Is surgical treatment of hepatocellular carcinoma at high-volume centers worth the additional cost? Surgery 2024; 175:629-636. [PMID: 37741780 DOI: 10.1016/j.surg.2023.06.044] [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: 04/05/2023] [Revised: 06/02/2023] [Accepted: 06/18/2023] [Indexed: 09/25/2023]
Abstract
BACKGROUND Case volume has been associated with improved outcomes for patients undergoing treatment for hepatocellular carcinoma, often with higher hospital expenditures. We sought to define the cost-effectiveness of hepatocellular carcinoma treatment at high-volume centers. METHODS Patients diagnosed with hepatocellular carcinoma from 2013 to 2017 were identified from Medicare Standard Analytic Files. High-volume centers were defined as the top decile of facilities performing hepatectomies in a year. A multivariable generalized linear model with gamma distribution and a restricted mean survival time model were used to estimate costs and survival differences relative to high-volume center status. The incremental cost-effectiveness ratio was used to define the additional cost incurred for a 1-year incremental gain in survival. RESULTS Among 13,666 patients, 8,467 (62.0%) were treated at high-volume centers. Median expenditure was higher ($19,148, interquartile range $15,280-$29,128) among patients treated at high-volume centers versus low-volume centers ($18,209, interquartile range $14,959-$29,752). Despite similar median length-of-stay (6 days, interquartile range 4-9), a slightly higher proportion of patients were discharged to home from high-volume centers (n = 4,903, 57.9%) versus low-volume centers (n = 2,868, 55.2%) (P = .002). A 0.14-year (95% confidence interval 0.06-0.22) (1 month and 3 weeks) survival benefit was associated with an incremental cost of $1,070 (95% confidence interval $749-$1,392) among patients undergoing surgery at high-volume centers. The incremental cost-effectiveness ratio for treatment at a high-volume center was $7,951 (95% confidence interval $4,236-$21,217) for an additional year of survival, which was below the cost-effective threshold of $21,217. CONCLUSION Surgical care at high-volume centers offers the potential to deliver cancer care in a more cost-effective and value-based manner.

Abstract
BACKGROUND We sought to determine the impact of historical redlining on travel patterns and utilization of high-volume hospitals (HVHs) among patients undergoing complex cancer operations. METHODS The California Department of Health Care Access and Information database was utilized to identify patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR) for cancer between 2010 and 2020. Patient ZIP codes were assigned Home Owners' Loan Corporation grades (A: 'Best'; B: 'Still Desirable'; C: 'Definitely Declining'; and D: 'Hazardous/Redlined'). A clustered multivariable regression was used to assess the likelihood of patients undergoing surgery at an HVH, bypassing the nearest HVH, and total real driving time and travel distance. RESULTS Among 14,944 patients undergoing high-risk cancer surgery (ES: 4.7%, n = 1216; PN: 57.8%, n = 8643; PD: 14.4%, n = 2154; PR: 23.1%, n = 3452), 782 (5.2%) individuals resided in the 'Best', whereas 3393 (22.7%) individuals resided in redlined areas. Median travel distance was 7.8 miles (interquartile range [IQR] 4.1-14.4) and travel time was 16.1 min (IQR 10.7-25.8). Overall, 10,763 (ES: 17.4%; PN: 76.0%; PA: 63.5%; PR: 78.4%) patients underwent surgery at an HVH. On multivariable regression, patients residing in redlined areas were less likely to undergo surgery at an HVH (odds ratio [OR] 0.67, 95% confidence interval [CI] 0.54-0.82) and were more likely to bypass the nearest hospital (OR 1.80, 95% CI 1.44-2.46). Notably, Medicaid insurance, minority status, limited English-language proficiency, and educational level mediated the disparities in access to HVH. CONCLUSION Surgical disparities in access to HVH among patients from historically redlined areas are largely mediated by social determinants such as insurance and minority status.

Abstract
Importance US surgical quality improvement (QI) programs use data from a systematic sample of surgical cases, rather than universal review of all cases, to assess and compare risk-adjusted hospital postoperative complication rates. Given decreasing postoperative complication rates over time and the types of cases eligible for abstraction, it is unclear whether case sampling is robust for identifying hospitals with higher than expected complications. Objective To compare the assessment of hospital 30-day complication rates derived from sampling strategy used by some US surgical QI programs relative to universal review of all cases. Design, Setting, and Participants This US hospital-level analysis took place from January 1, 2016, through September 30, 2020. Data analysis was performed from July 1, 2022, through December 21, 2022. Quarterly, risk-adjusted, 30-day complication observed to expected (O-E) ratios were calculated for each hospital using the sample (n = 502 730) and universal review (n = 1 725 364). Outlier hospitals (ie, those with higher than expected mortality) were identified using an O-E ratio significantly greater than 1.0. Patients 18 years and older who underwent a noncardiac operation at US Department of Veterans Affairs (VA) hospitals with a record in the VA Surgical Quality Improvement Program (systematic sample) and the VA Corporate Data Warehouse surgical domain (100% of surgical cases) were included. Main Outcome Measure Thirty-day complications. Results Most patients in both the representative sample and the universal sample were men (90.2% vs 91.2%) and White (74.7% vs 74.5%). Overall, 30-day complication rates were 7.6% and 5.3% for the sample and universal review cohorts, respectively (P < .001). Over 2145 hospital quarters of data, hospitals were identified as an outlier in 15.0% of quarters using the sample and 18.2% with universal review. Average hospital quarterly complication rates were 4.7%, 7.2%, and 7.4% for outliers identified using the sample only, universal review only, and concurrent identification in both data sources, respectively. For nonsampled cases, average hospital quarterly complication rates were 7.0% at outliers and 4.4% at nonoutliers. Among outlier hospital quarters in the sample, 54.2% were concurrently identified with universal review. For those identified with universal review, 44.6% were concurrently identified using the sample. Conclusion In this observational study, case sampling identified less than half of hospitals with excess risk-adjusted postoperative complication rates. Future work is needed to ascertain how to best use currently collected data and whether alternative data collection strategies may be needed to better inform local QI efforts.

Quantitative edge analysis of pancreatic margins in patients with head pancreatic tumors: correlations between pancreatic margins and the onset of postoperative pancreatic fistula. Eur Radiol 2024; 34:1515-1523. [PMID: 37658898 DOI: 10.1007/s00330-023-10200-6] [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: 01/04/2023] [Revised: 07/09/2023] [Accepted: 07/20/2023] [Indexed: 09/05/2023]
Abstract
OBJECTIVE To assess the correlation between pancreatic quantitative edge analysis as a surrogate of parenchymal stiffness and the incidence of postoperative pancreatic fistula (POPF), in patients undergoing pancreaticoduodenectomy (PD). METHODS All consecutive patients who underwent PD at our Institution between March 2018 and November 2019 with an available preoperative CT were included. Pancreatic margin score (PMS) was calculated through computer-assisted quantitative edge analysis on the margins of the pancreatic body and tail (the expected pancreatic remnant) on non-contrast scans with in-house software. Intraoperative assessment of pancreatic stiffness by manual palpation was also performed, classifying pancreatic texture into soft and non-soft. PMS values were compared between groups using an unpaired T-test and correlated with the intraoperative evaluation of stiffness and with the grading of postoperative pancreatic fistula according to the International Study Group on Pancreatic Surgery (ISGPS). RESULTS Patient population included 200 patients (mean age 64.6 years), 146 without onset of POPF (73%, non-POPF group), and 54 with POPF (27%, POPF group). A significant difference in PMS values was observed between POPF and non-POPF (respectively 1.88 ± 0.05 vs 0.69 ± 0.01; p < 0.0001). PMS values of pancreatic parenchymas intraoperatively considered "soft" were significantly higher than those evaluated as "non-soft" (1.21 ± 0.04 vs 0.73 ± 0.02; p < 0.0001). A significant correlation between PMS values and POPF grade was observed (r = 0.8316), even in subgroups of patients with soft (r = 0.8016) and non-soft (r = 0.7602) pancreas (all p < 0.0001). CONCLUSIONS Quantitative edge analysis with dedicated software may stratify patients with different pancreatic stiffness, thus potentially improving preoperative risk assessment and strategies for POPF mitigation. CLINICAL RELEVANCE STATEMENT This study proposes quantitative pancreas edge analysis as a predictor for postoperative pancreatic fistula. The test has high accuracy and correlation with fistula grade according to the International Study Group on Pancreatic Surgery. KEY POINTS • Prediction of postoperative pancreatic fistula (POPF) onset risk after pancreaticoduodenectomy is based only on intraoperative evaluation. • Quantitative edge analysis may preoperatively identify patients with higher risk of POPF. • Quantification of pancreatic stiffness through the analysis of pancreatic margins could be done on preoperative CT.

Risk Factor Analysis for Developing Major Complications Following Esophageal Surgery-A Two-Center Study. J Clin Med 2024; 13:1137.

Abstract
BACKGROUND Esophagectomy carries a high risk of morbidity and mortality compared to other major surgeries. With the aim of creating an easy-to-use clinical preoperative risk assessment tool and to validate previously described risk factors for major complications following surgery, esophagectomies at two tertiary medical centers were analyzed. METHODS A total of 450 patients who underwent esophagectomy for esophageal carcinoma at the University Medical Centre, Hamburg, or at the Medical Center University Duisburg-Essen, Germany (January 2008 to January 2020) were retrospectively analyzed. Epidemiological and perioperative data were analyzed to identify the risk factors that impact major complication rates. The primary endpoint of this study was to determine the incidence of major complications. RESULTS The mean age of the patients was 63 years with a bimodal distribution. There was a male predominance across the cohort (81% vs. 19%, respectively). Alcohol abuse (p = 0.0341), chronic obstructive pulmonary disease (p = 0.0264), and cardiac comorbidity (p = 0.0367) were associated with a significantly higher risk of major complications in the multivariate analysis. Neoadjuvant chemotherapy significantly reduced the risk of major postoperative complications (p < 0.0001). CONCLUSIONS Various patient-related risk factors increased the rate of major complications following esophagectomy. Patient-tailored prehabilitation programs before esophagectomy that focus on minimizing these risk factors may lead to better surgical outcomes and should be analyzed in further studies.

JCO Oncol Pract 2024; 20:278-290. [PMID: 38086003 PMCID: PMC10911581 DOI: 10.1200/op.23.00495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/05/2023] [Accepted: 10/30/2023] [Indexed: 12/19/2023] Open
Abstract
PURPOSE We evaluated the potential cost-effectiveness of combined magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) screening for pancreatic ductal adenocarcinoma (PDAC) among populations at high risk for the disease. METHODS We used a microsimulation model of the natural history of PDAC to estimate the lifetime health benefits, costs, and cost-effectiveness of PDAC screening among populations with specific genetic risk factors for PDAC, including BRCA1 and BRCA2, PALB2, ATM, Lynch syndrome, TP53, CDKN2A, and STK11. For each high-risk population, we simulated 29 screening strategies, defined by starting age and frequency. Screening included MRI with follow-up EUS in a subset of patients. Costs of tests were based on Medicare reimbursement for MRI, EUS, fine-needle aspiration biopsy, and pancreatectomy. Cancer-related cost by stage of disease and phase of treatment was based on the literature. For each high-risk population, we performed an incremental cost-effectiveness analysis, assuming a willingness-to-pay (WTP) threshold of $100,000 US dollars (USD) per quality-adjusted life year (QALY) gained. RESULTS For men with relative risk (RR) 12.33 (CDKN2A) and RR 28 (STK11), annual screening was cost-effective, starting at age 55 and 40 years, respectively. For women, screening was only cost-effective for those with RR 28 (STK11), with annual screening starting at age 45 years. CONCLUSION Combined MRI/EUS screening may be a cost-effective approach for the highest-risk populations (among mutations considered, those with RR >12). However, for those with moderate risk (RR, 5-12), screening would only be cost-effective at higher WTP thresholds (eg, $200K USD/QALY) or with once-only screening.

Abstract
BACKGROUND In 2006, Cancer Care Ontario created Surgical Oncology Standards for the delivery of hepatopancreatobiliary (HPB) surgery including hepatectomy and pancreaticoduodenectomy (PD). Our objective was to identify the impact of standardization on outcomes after HPB surgery in Ontario, Canada. STUDY DESIGN This study was a population-level analysis of patients undergoing hepatectomy or PD (2003 to 2019). Logistic regression models were used to compare 30- and 90-day mortality and length of stay (LOS) before (2003 to 2006), during (2007 to 2011), and after (2012 to 2019) standardization. Interrupted time series models were used to co-analyze secular trends. RESULTS A total of 7,904 hepatectomies and 5,238 PDs were performed. More than 80% of all cases were performed at a designated center (DC) before standardization. This increased to >98% in the poststandardization era. Median volumes at DCs increased from 55 to 67 hepatectomies/year and from 22 to 50 PDs/year over time. In addition, 30-day mortality after hepatectomy was 2.6% before standardization and 2.3% after standardization (p = 0.9); 30-day mortality after PD was 3.6% before standardization and 2.4% after standardization (p = 0.1). Multivariable analyses revealed a significant difference in 90-day mortality following PD poststandardization (4.3% vs 6.3%; adjusted odds ratio, 0.7; p = 0.03). Median LOS was shorter for hepatectomy (6 days vs 8 days) and PD (9 days vs 14 days; p < 0.0001) after standardization. Immediate and late effects on mortality and LOS were likely attributable to secular trends, which predated standardization. CONCLUSIONS Standardization was associated with a higher volume of hepatectomy and PDs with further concentration of care at DCs. Pre-existing quality initiatives may have attenuated the effect of standardization on quality outcomes. Our data highlight the merits of a multifaceted provincial system for enabling consistent access to high quality HPB care throughout a region of 15 million people over a 16-year period.

Abstract
BACKGROUND The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) population is among the fastest-growing population in the USA. However, this is not reflected in scientific research, in which ethnic groups are often combined. We identified trends in treatment and outcomes for pancreatic cancer in a disaggregated AANHPI population. We hypothesize that patients from different AANHPI groups have differences in survival. PATIENTS AND METHODS A retrospective analysis of the National Cancer Database between 2010 and 2019 identified patients treated for pancreatic cancer. We identified demographic factors for patients of Caucasian, African American, and disaggregated Asian subpopulations. Survival curves were generated and multivariate analysis was performed to help determine which factors impacted overall survival. RESULTS A total of 296,448 patients met the inclusion criteria. Of those, 8568 (3%) patients were Asian. Median survival of AANHPI patients was 11.3 months, as compared with Caucasians (8.9 months) and African Americans (8.1 months) (p < 0.0001). Asian Indians had the highest median survival (14.3 months), whereas the Japanese subpopulation had the lowest (7.6 months) (p < 0.0001). There were significant differences in median survival between the different AANHPI subpopulations irrespective of stage. Multivariate analysis demonstrated that belonging to an AANHPI racial/ethnic group, excluding Japanese and Filipino, was associated with decreased risk of overall mortality. DISCUSSION Significant differences were identified in the overall median survival for patients with pancreatic cancer between AANHPI subpopulations. Disparities in socioeconomic factors may have played a role in overall survival. This study highlights the need to include disaggregated data in future studies to subdue disparities in cancer care for patients.

Abstract
OBJECTIVES To determine a data-based optimal annual radical cystectomy (RC) hospital volume threshold and evaluate its clinical significance regarding perioperative mortality, complications, length of hospital stay, and hospital revenues. MATERIAL AND METHODS We used the German Nationwide inpatient Data, provided by the Research Data Center of the Federal Bureau of Statistics (2005-2020). 95,841 patients undergoing RC were included. Based on ROC analyses, the optimal RC threshold to reduce mortality, ileus, sepsis, transfusion, hospital stay, and costs is 54, 50, 44, 44, 71 and 76 cases/year, respectively. Therefore, we defined an optimal annual hospital threshold of 50 RCs/year, and we also used the threshold of 20 RCs/year proposed by the EAU guidelines to perform multiple patient-level analyses. RESULTS 28,291 (29.5%) patients were operated in low- (< 20 RC/year), 49,616 (51.8%) in intermediate- (20-49 RC/year), and 17,934 (18.7%) in high-volume (≥ 50 RC/year) centers. After adjusting for major risk factors, high-volume centers were associated with lower inpatient mortality (OR 0.72, 95% CI 0.64-0.8, p < 0.001), shorter length of hospital stay (2.7 days, 95% CI 2.4-2.9, p < 0.001) and lower costs (457 Euros, 95% CI 207-707, p < 0.001) compared to low-volume centers. Patients operated in low-volume centers developed more perioperative complications such as transfusion, sepsis, and ileus. CONCLUSIONS Centralization of RC not only improves inpatient morbidity and mortality but also reduces hospital stay and costs. We propose a threshold of 50 RCs/year for optimal outcomes.

[PMID: 38247946 PMCID: PMC10812999 DOI: 10.3390/bioengineering11010069] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Revised: 12/01/2023] [Accepted: 01/04/2024] [Indexed: 01/23/2024] Open
Abstract
Hyperspectral imaging (HSI) is a non-invasive and contactless technique that enables the real-time acquisition of comprehensive information on tissue within the surgical field. In this pilot study, we investigated whether a new HSI system for minimally-invasive surgery, TIVITA® Mini (HSI-MIS), provides reliable insights into tissue perfusion of the proximal and distal esophagogastric anastomotic sites during 21 laparoscopic/thoracoscopic or robotic Ivor Lewis esophagectomies of patients with cancer to minimize the risk of dreaded anastomotic insufficiency. In this pioneering investigation, physiological tissue parameters were derived from HSI measurements of the proximal site of the anastomosis (esophageal stump) and the distal site of the anastomosis (tip of the gastric conduit) during the thoracic phase of the procedure. Tissue oxygenation (StO2), Near Infrared Perfusion Index (NIR-PI), and Tissue Water Index (TWI) showed similar median values at both anastomotic sites. Significant differences were observed only for NIR-PI (median: 76.5 vs. 63.9; p = 0.012) at the distal site (gastric conduit) compared to our previous study using an HSI system for open surgery. For all 21 patients, reliable and informative measurements were attainable, confirming the feasibility of HSI-MIS to assess anastomotic viability. Further studies on the added benefit of this new technique aiming to reduce anastomotic insufficiency are warranted.

Abstract
BACKGROUND Postpancreatectomy hemorrhage (PPH) is a rare yet dreaded complication following pancreaticoduodenectomy (PD). This retrospective study aimed to explore a machine learning (ML) model for predicting PPH in PD patients. METHODS A total of 284 patients who underwent open PD at our institute were included in the analysis. To address the issue of imbalanced data, the adaptive synthetic sampling (ADASYN) technique was employed. The best-performing ML model was selected using the PyCaret library in Python and evaluated based on recall, precision, and F1 score metrics. In addition to assessing the model's performance on the test data, bootstrap validation (n = 1000) with the original dataset was conducted. RESULTS PPH occurred in 11 patients (3.9%), with a median onset time of 22 days postoperatively. These minority cases were oversampled to 85 using ADASYN. The extra trees classifier demonstrated superior performance with recall, precision, and F1 score of 0.967, 0.914, and 0.937, respectively. Both validation using the test data and bootstrap resampling consistently demonstrated recall, precision, and F1 score exceeding 0.9. The model identified the peak value of C-reactive protein during the first 7 postoperative days as the most significant feature, followed by the preoperative neutrophil-to-lymphocyte ratio. CONCLUSIONS This study highlights the potential of the ML approach to predict PPH occurrence following PD. Vigilance and early interventions guided by such model predictions could positively impact outcomes for high-risk patients.

Abstract
Healthcare is increasingly delivered through networks of organizations. Well-structured patient sharing networks are known to have positive associations with the quality of delivered services. However, the drivers of patient sharing relations are rarely studied explicitly. In line with recent developments in network and integration theorizing, we hypothesize that structural and social network ties between organizations are uniquely associated with a higher number of shared patients. We test these hypotheses using a Bayesian zero-dispersed Poisson regression model within the Additive and Multiplicative Effects Framework based on administrative claims data from 732,122 dermatological patients from the Netherlands in 2017. Our results indicate that 2.6% of all dermatological patients are shared and that the amount of shared patients is significantly associated with structural (i.e. emergency contracts) and social (i.e. shared physicians) ties between organizations, confirming our hypotheses. We also find some evidence that patients are shared with more capable organizations. Our findings highlight the role of relational ties in the way health services are delivered. At the same time, they also raise some potential anti-trust concerns.

Abstract
PURPOSE The aim of this study was to assess how physicians perceive the role of the reimbursement system and its potential influence in affecting their treatment choice in the management of patients affected by osteoarthritis (OA). METHODS A survey was administered to 283 members of SIAGASCOT (Italian Society of Arthroscopy, Knee, Upper Limb, Sport, Cartilage and Orthopaedic Technologies), a National scientific orthopaedic society. The survey presented multiple choice questions on the access allowed by the current Diagnosis-Related Groups (DRG) system to all necessary options to treat patients affected by OA and on the influence toward prosthetic solutions versus other less invasive options. RESULTS Almost 70% of the participants consider that the current DRG system does not allow access to all necessary options to best treat patients affected by OA. More than half of the participants thought that the current DRG system favors the choice of prosthetic solutions (55%) and that it can contribute to the increase in prosthetic implantation at the expense of less invasive solutions (54%). The sub-analyses based on different age groups, professional roles, and places of work allowed to evaluate the response in each specific category, confirming the findings for all investigated aspects. CONCLUSIONS This survey documented that the majority of physicians consider that the reimbursement system can influence the treatment choice when managing OA patients. The current DRG system was perceived as unbalanced in favor of the choice of the prosthetic solution, which could contribute to the increase in prosthetic implantation at the expense of other less invasive options for OA management.

Abstract
To evaluate the success rates of percutaneous drainage for fluid collection after radical cystectomy, with emphasis on factors affecting the clinical success, including lesion, patient, and procedure characteristics. In this retrospective study, 31 percutaneous drainage catheters were placed in 29 consecutive patients between January 2021 and September 2023. Most fluid collections formed near the uretero-ileal anastomosis site in the right pelvic cavity (80.6%). The technical success rate was 100%. The primary and final clinical success was 80.6% and 96.9%, respectively. Lymphoceles notably increased the primary clinical failure risk (odds ratio and 95% confidential interval: 22.667 (1.839-279.366), P = .015). Significant differences were observed between transabdominal and transgluteal approaches in terms of fluoroscopic time, dose, and location. Leakage indications on computed tomography prompted differing interventions, but all achieved final clinical success. Percutaneous drainage for post-operative fluid collection is safe and effective in patients with radical cystectomy and urinary diversion.

Abstract
INTRODUCTION In response to intense market pressures, many hospitals have consolidated into systems. However, evidence suggests that consolidation has not led to the improvements in clinical quality promised by proponents of mergers. The challenges to delivering care within expanding health systems and the opportunities posed to surgical leaders remains largely unexplored. METHODS Semistructured interviews with 30 surgical leaders at teaching hospitals affiliated with health systems from August-December 2019. Interviews were transcribed verbatim and coded in an iterative process using MaxQDA software. Attitudes and strategies toward redesigning health care delivery across expanding systems were analyzed using thematic analysis. RESULTS Leaders reported challenges to redesigning care delivery across the system ranging from resource constraints (e.g. hospital beds and operating rooms) to evolving market demands (e.g., patient preferences to receive care close to home). However, participants also highlighted that system expansion provided multiple opportunities to increase access (e.g. decant low-complexity care to affiliated centers) and improve quality of care (e.g. standardize best practices) for diverse populations including the potential to leverage their health system to expand access and improve quality. CONCLUSIONS Though evidence suggests that hospital consolidation has not led to redesigned care delivery or improved clinical quality at a national level, leaders are pursuing varying sets of strategies aimed at leveraging system expansion in order to improve access and quality of care.

Abstract
INTRODUCTION Regionalization of complex surgical procedures may improve healthcare quality. We sought to define the impact of regionalization on access to high-volume hospitals for complex oncologic procedures in the state of California. METHODS The California Department of Health Care Access and Information Database (2012-2016) identified patients who underwent esophagectomy (ES), pneumonectomy (PN), pancreatectomy (PA), or proctectomy (PR). Geospatial analysis was conducted to determine travel patterns. Clustered multivariable regression was performed to assess the probability of receiving care at a high-volume center. RESULTS Among 25,070 patients (ES: n = 1216, 4.9%; PN: n = 13,247, 52.8%; PD: n = 3559, 14.2%; PR: n = 7048, 28.1%), 6575 (26.2%) individuals resided within 30 min, 11,046 (44.1%) resided within 30-60 min, 7125 (28.4%) resided within 60-90 min, and 324 (1.3%) resided beyond a 90-min travel window from a high-volume center. Median travel distance was 13.4 miles (interquartile range [IQR] 6.0-28.7). On multivariable regression, patients residing further away were more likely to bypass a low-volume center to undergo care at a high-volume hospital (odds ratio 1.32, 95% confidence interval 1.12-1.55) versus individuals residing closer to high-volume centers. Approximately one-third (29.7%) of patients lived beyond a 1-h travel window to the nearest high-volume hospital, of whom 5% traveled over 90 min. While hospital mortality rates across different travel time windows did not differ, surgery at a high-volume center was associated with an overall 1.2% decrease in in-hospital mortality. CONCLUSIONS Regionalization of complex cancer surgery may be associated with a significant travel burden for a large subset of patients with complex cancer.
