RESUMO
BACKGROUND: We sought to assess the impact of various perioperative factors on the risk of severe complications and post-surgical mortality using a novel maching learning technique. METHODS: Data on patients undergoing resection for HCC were obtained from an international, multi-institutional database between 2000 and 2020. Gradient boosted trees were utilized to construct predictive models. RESULTS: Among 962 patients who underwent HCC resection, the incidence of severe postoperative complications was 12.7% (n = 122); in-hospital mortality was 2.9% (n = 28). Models that exclusively used preoperative data achieved AUC values of 0.89 (95%CI 0.85 to 0.92) and 0.90 (95%CI 0.84 to 0.96) to predict severe complications and mortality, respectively. Models that combined preoperative and postoperative data achieved AUC values of 0.93 (95%CI 0.91 to 0.96) and 0.92 (95%CI 0.86 to 0.97) for severe morbidity and mortality, respectively. The SHAP algorithm demonstrated that the factor most strongly predictive of severe morbidity and mortality was postoperative day 1 and 3 albumin-bilirubin (ALBI) scores. CONCLUSION: Incorporation of perioperative data including ALBI scores using ML techniques can help risk-stratify patients undergoing resection of HCC.
RESUMO
BACKGROUND: Primary care (PC) is essential to overall wellness and management of comorbidities. In turn, patients without adequate access to PC may face healthcare disparities. We sought to characterize the impact of established PC on postoperative outcomes among patients undergoing a surgical procedure for a digestive tract cancer. METHODS: Medicare beneficiaries with a diagnosis of hepatobiliary, pancreas, and colorectal cancer between 2005 and 2019 were identified within the Surveillance, Epidemiology, and End Results program and Medicare-linked database. Individuals who did versus did not have PC encounters within 1-year before surgery were identified. A postoperative textbook outcome (TO) was defined as the absence of complications, no prolonged hospital stay, no readmission within 90 days, and no mortality. RESULTS: Among 63,177 patients, 50,974 (80.7%) had at least one established PC visit before surgery. Patients with established PC were more likely to achieve TO (odds ratio [OR], 1.14; 95% confidence interval [CI], 1.09-1.19) with lower odds for complications (OR, 0.85; 95% CI, 0.72-0.89), extended hospital stay (OR, 0.86; 95% CI, 0.81-0.94), 90-day readmission (OR, 0.94; 95% CI, 0.90-0.99), and 90-day mortality (OR, 0.87; 95% CI, 0.79-0.96). In addition, patients with established PC had a 4.1% decrease in index costs and a 5.2% decrease in 1-year costs. Notably, patients who had one to five visits with their PC in the year before surgery had improved odds of TO (OR, 1.21; 95% CI, 1.16-1.27), whereas individuals with more than 10 visits had lower odds of a postoperative TO (OR, 0.91; 95% CI, 0.84-0.98). CONCLUSION: Most Medicare beneficiaries with digestive tract cancer had established PC within the year before their surgery. Established PC was associated with a higher probability of achieving ideal outcomes and lower costs. In contrast, patients with more than 10 PC appointments, which was likely a surrogate of overall comorbidity burden, experienced no improvement in postoperative outcomes.
RESUMO
OBJECTIVE: We sought to define the association of privilege on rates of unplanned surgery and perioperative outcomes for access-sensitive surgical conditions. BACKGROUND: Social determinants of health (SDOH) are critical in influencing timely access to healthcare. Privilege represents a right, benefit, advantage, or opportunity that positively influences all SDOH. METHODS: The California Department of Health Care Access and Information (HCAI) database identified patients who underwent abdominal aortic aneurysm repair, ventral hernia repair, or colectomy for colon cancer between 2017 and 2020 and was merged using ZIP codes with the Index of Concentration of Extremes, a validated measure of racial and economic privilege obtained from the American Community Survey. Clustered multivariable regression was performed to assess the association between privilege and outcomes. RESULTS: Among 185,316 patients who underwent a surgical procedure for one of three access-sensitive surgical conditions, roughly 1 in 5 individuals resided in areas with the highest (Q5; n=37,308; 20.1%) or lowest (Q1; n=36,352, 19.6%) privilege. Nearly one-half of the surgeries were unplanned (n=88,814, 46.9%), and colectomy for colon cancer was the most performed emergent procedure. Patients residing in the lowest privileged areas had higher rates of unplanned surgery compared with those residing in the highest privilege (Q1; 55.4% vs. 39.4%; referent: Q5; adjusted odds ratio [OR], 1.23, 95%CI 1.16-1.31; P<0.001). For each access-sensitive surgical condition, patients in the least privileged areas were more likely to experience higher rates of inpatient mortality (Q1; 3.1% vs. 2.1%; referent: Q5; adjusted OR, 1.41, 95%CI 1.24-1.60; P<0.001), perioperative complications (Q1; 30.4% vs. Q5; 23.8%; referent: Q5; adjusted OR, 1.24, 95%CI 1.18-1.31; P<0.001) and extended hospital stays (Q1; 26.3% vs. 20.1%; referent: Q5; adjusted OR, 1.16, 95%CI 1.09-1.22; P<0.001). CONCLUSIONS AND RELEVANCE: Privilege was associated with rates of unplanned surgery and adverse clinical outcomes. This indicates the role privilege as a key SDOH that influences patient access to and quality of surgical care.
RESUMO
INTRODUCTION: Environmental hazards may influence health outcomes and be a driver of health inequalities. We sought to characterize the extent to which social-environmental inequalities were associated with surgical outcomes following a complex operation. METHODS: In this cross-sectional study, patients who underwent abdominal aortic aneurysm repair, coronary artery bypass grafting, colectomy, pneumonectomy, or pancreatectomy between 2016 and 2021 were identified from Medicare claims data. Patient data were linked with social-environmental data sourced from Centers for Disease Control and Agency for Toxic Substances and Disease Registry data based on county of residence. The Environmental Justice Index social-environmental ranking (SER) was used as a measure of environmental injustice. Multivariable regression analysis was performed to assess the relationship between SER and surgical outcomes. RESULTS: Among 1,052,040 Medicare beneficiaries, 346,410 (32.9%) individuals lived in counties with low SER, while 357,564 (33.9%) lived in counties with high SER. Patients experiencing greater social-environmental injustice were less likely to achieve textbook outcome (odds ratio 0.95, 95% confidence interval 0.94-0.96, P < 0.001) and to be discharged to an intermediate care facility or home with a health agency (odds ratio 0.97, 95% confidence interval 0.96-0.98, P < 0.001). CONCLUSIONS: Cumulative social and environmental inequalities, as captured by the Environmental Justice Index SER, were associated with postoperative outcomes among Medicare beneficiaries undergoing a range of surgical procedures. Policy makers should focus on environmental, as well as socioeconomic injustice to address preventable health disparities.
RESUMO
BACKGROUND: Access to healthcare providers is a key factor in reducing cancer incidence and mortality, underscoring the significance of provider density as a crucial metric of health quality. We sought to characterize the association of provider density on hepatobiliary cancer population-level incidence and mortality. STUDY DESIGN: County-level hepatobiliary cancer incidence and mortality data from 2016 to 2020 and provider data from 2016 to 2018 were obtained from the CDC and Area Health Resource File. Multivariable logistic regression was utilized to evaluate the relationship between provider density and hepatobiliary cancer incidence and mortality. RESULTS: Among 1359 counties, 851 (62.6%) and 508 (37.4%) counties were categorized as urban and rural, respectively. The median number of providers in any given county was 104 (IQR: 44-306), while provider density was 120.1 (IQR: 86.7-172.2) per 100,000 population; median household income was $51,928 (IQR: $45,050-$61,655). Low provider-density counties were more likely to have a greater proportion of residents over 65 years of age (52.7% vs. 49.6%) who were uninsured (17.4% vs. 13.2%) versus higher provider-density counties (p < 0.05). Moreover, all-stage incidence, late-stage incidence, and mortality rates were higher in counties with low provider density. On multivariable analysis, moderate, and high provider density were associated with lower odds of all-stage incidence, late-stage incidence, and mortality. CONCLUSION: Higher county-level provider density was associated with lower hepatobiliary cancer-related incidence and mortality. Efforts to increase access to healthcare providers may improve healthcare equity as well as long-term cancer outcomes.
RESUMO
INTRODUCTION: Accurate prediction of patients at risk for early recurrence (ER) among patients with colorectal liver metastases (CRLM) following preoperative chemotherapy and hepatectomy remains limited. METHODS: Patients with CRLM who received chemotherapy prior to undergoing curative-intent resection between 2000 and 2020 were identified from an international multi-institutional database. Multivariable Cox regression analysis was used to assess clinicopathological factors associated with ER, and an online calculator was developed and validated. RESULTS: Among 768 patients undergoing preoperative chemotherapy and curative-intent resection, 128 (16.7 %) patients had ER. Multivariable Cox analysis demonstrated that Eastern Cooperative Oncology Group Performance status ≥1 (HR 2.09, 95%CI 1.46-2.98), rectal cancer (HR 1.95, 95%CI 1.35-2.83), lymph node metastases (HR 2.39, 95%CI 1.60-3.56), mutated Kirsten rat sarcoma oncogene status (HR 1.95, 95%CI 1.25-3.02), increase in tumor burden score during chemotherapy (HR 1.51, 95%CI 1.03-2.24), and bilateral metastases (HR 1.94, 95%CI 1.35-2.79) were independent predictors of ER in the preoperative setting. In the postoperative model, in addition to the aforementioned factors, tumor regression grade was associated with higher hazards of ER (HR 1.91, 95%CI 1.32-2.75), while receipt of adjuvant chemotherapy was associated with lower likelihood of ER (HR 0.44, 95%CI 0.30-0.63). The discriminative accuracy of the preoperative (training: c-index: 0.77, 95%CI 0.72-0.81; internal validation: c-index: 0.79, 95%CI 0.75-0.82) and postoperative (training: c-index: 0.79, 95%CI 0.75-0.83; internal validation: c-index: 0.81, 95%CI 0.77-0.84) models was favorable (https://junkawashima.shinyapps.io/CRLMfollwingchemotherapy/). CONCLUSIONS: Patient-, tumor- and treatment-related characteristics in the preoperative and postoperative setting were utilized to develop an online, easy-to-use risk calculator for ER following resection of CRLM.
RESUMO
Importance: Gender inequities and limited representation are an obstacle to surgical workforce diversification. There has been limited examination of gender-based disparities in billing practices among surgeons. Objective: To evaluate variations in practice metrics and billing practices among female and male surgeons and identify factors associated with gender disparities in Medicare reimbursements. Design, Setting, and Participants: This retrospective cross-sectional study used publicly available Medicare Fee-for-Service Provider Utilization and Payment data from January to December 31, 2021, to identify demographics, annual services provided, and financial payments and charges for general surgeons, surgical oncologists, and colorectal surgeons. Data were analyzed from November 2023 to February 2024. Exposure: The primary exposure of interest was surgeon gender (ie, female or male). Main Outcomes and Measures: The annual total submitted charges and payments submitted in 2021 by female and male surgeons were assessed. Additionally, the total number and types of services provided each year and the number of beneficiaries treated were examined. Multivariable linear regression models were used to evaluate the association of surgeon gender with payments, number of services, and beneficiaries. Results: A total of 20â¯549 general surgeons (5036 [24.5%] female; 15â¯513 [75.5%] male), 1065 surgical oncologists (450 [42.3%] female; 615 [57.7%] male), and 1601 colorectal surgeons (432 [27.0%] female; 1169 [73.0%] male) were included. Across all surgical subspecialties, female surgeons billed fewer mean (SE) Medicare charges (general surgeons: 30.1% difference; $224â¯934.80 [$3846.97] vs $321â¯868.50 [$3933.57]; surgical oncologists: 27.5% difference; $277â¯901.70 [$22â¯857.37] vs $382â¯882.90 [$19â¯566.06]; colorectal surgeons: 21.7% difference; $274â¯091.70 [$10â¯468.48] vs $350â¯146.10 [$8741.66]; all P < .001) and received significantly lower mean (SE) reimbursements (general surgeons: 29.0% difference; $51â¯787.61 [$917.91] vs $72â¯903.12 [$890.35]; surgical oncologists: 23.6% difference; $57â¯945.18 [$3853.28] vs $75â¯778.22 [$2622.75]; colorectal surgeons: 24.5% difference; $63â¯117.01 [$2248.10] vs $83â¯598.53 [$1934.77]; all P < .001). On multivariable analysis, a reimbursement gap remained across all 3 surgical subspecialties (general surgeons: -$14â¯963.46 [95% CI, -$18â¯822.27 to -$11â¯104.64] [P < .001]; surgical oncologists: -$8354.69 [95% CI, -$15â¯018.12 to -$1691.25] [P = .01]; colorectal surgeons: -$4346.73 [95% CI, -$7660.15 to -$1033.32] [P = .01]). Conclusions and Relevance: In this cross-sectional study, there was considerable gender-based variation in practice patterns and reimbursement among different surgical subspecialties serving the Medicare population. Differences in mean payment per service were associated with variations in billing and coding strategies among female and male surgeons.
RESUMO
BACKGROUND AND OBJECTIVES: Surgeon sex has been associated with perioperative clinical outcomes among patients undergoing oncologic surgery. There may be variations in financial outcomes relative to the surgeon-patient dyad. We sought to define the association of surgeon's sex with perioperative financial outcomes following cancer surgery. METHODS: Patients who underwent resection of lung, breast, hepato-pancreato-biliary (HPB), or colorectal cancer between 2014 and 2021 were identified from the Medicare Standard Analytic Files. A generalized linear model with gamma regression was utilized to characterize the association between sex concordance and expenditures. RESULTS: Among 207,935 Medicare beneficiaries (breast: n = 14,753, 7.1%, lung: n = 59,644, 28.7%, HPB: n = 23,400, 11.3%, colorectal: n = 110,118, 53.0%), 87.8% (n = 182,643) and 12.2% (n = 25,292) of patients were treated by male and female surgeons, respectively. On multivariable analysis, female surgeon sex was associated with slightly reduced index expenditures (mean difference -$353, 95%CI -$580, -$126; p = 0.003). However, there were no differences in 90-day post-discharge inpatient (mean difference -$-225, 95%CI -$570, -$121; p = 0.205) and total expenditures (mean difference $133, 95%CI -$279, $545; p = 0.525). CONCLUSIONS: There was minor risk-adjusted variation in perioperative expenditures relative to surgeon sex. To improve perioperative financial outcomes, a diverse surgical workforce with respect to patient and surgeon sex is warranted.
RESUMO
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.

BACKGROUND: We sought to assess the impact of telemedicine on healthcare utilization and medical expenditures among patients with a diagnosis of gastrointestinal (GI) cancer. METHODS: Patients with newly diagnosed GI cancer from 2013 to 2020 were identified from the IBM MarketScan database (IBM Watson Health) . Healthcare utilization, total medical outpatient insurance payments within 1 year post-diagnosis, and out-of-pocket (OOP) expenses among telemedicine users and non-users were assessed after propensity score matching (PSM). RESULTS: Among the 32,677 patients with GI cancer (esophageal, n = 1862, 5.7%; gastric, n = 2009, 6.1%; liver, n = 2929, 9.0%; bile duct, n = 597, 1.8%; pancreas, n = 3083, 9.4%; colorectal, n = 22,197, 67.9%), a total of 3063 (9.7%) utilized telemedicine. After PSM (telemedicine users, n = 3064; non-users, n = 3064), telemedicine users demonstrated a higher frequency of clinic visits (median: 5.0 days, IQR 4.0-7.0 vs non-users: 2.0 days, IQR 2.0-3.0, P < .001) and fewer potential days missed from daily activities (median: 7.5 days, IQR 4.5-12.5 vs non-users: 8.5 days, IQR 5.5-13.5, P < .001). Total medical spending per month and utilization of emergency room (ER) visits for telemedicine users were higher vs non-users (median: $10,658, IQR $5112-$18,528 vs non-users: $10,103, IQR $4628-$16,750; 46.8% vs 42.6%, both P < .01), whereas monthly OOP costs were comparable (median: $273, IQR $137-$449 for telemedicine users vs non-users: $268, IQR $142-$434, P = .625). CONCLUSION: Telemedicine utilization was associated with increased outpatient clinic visits yet reduced potential days missed from daily activities among patients with GI cancer. Telemedicine users tended to have more ER visits and total medical spending per month, although monthly OOP costs were comparable with non-users.
RESUMO
BACKGROUND: Despite an established association with improved patient outcomes, compliance with National Comprehensive Cancer Network (NCCN) guidelines remains suboptimal. We sought to assess the effect of patient characteristics (PCs), operative characteristics (OCs), hospital characteristics (HCs), and social determinants of health (SDoH) on noncompliance with NCCN guidelines for colon cancer. METHODS: Patients treated for stage I to III colon cancer from 2004 to 2017 were identified from the National Cancer Database. Multilevel multivariate regression analysis was performed to identify factors associated with receipt of NCCN-compliant care and quantify the proportion of variance explained by PCs, OCs, HCs, and SDoH. RESULTS: Among 468,097 patients with colon cancer treated across 1319 hospitals, 1 in 4 patients did not receive NCCN-compliant care (122,170 [26.1%]). On regression analysis, older age (odds ratio [OR], 0.96; 95% CI, 0.96-0.96), female sex (OR, 0.97; 95% CI, 0.96-0.99), Black race (OR, 0.96; 95% CI, 0.94-0.98), higher Charlson-Deyo score (OR, 0.84; 95% CI, 0.82-0.86), tumor stage ≥II (OR, 0.42; 95% CI, 0.40-0.44), and tumor grade ≥ 3 (OR, 0.33; 95% CI, 0.32-0.34) were associated with lower odds of receiving NCCN-compliant care (all P values <.05). Higher hospital volume (OR, 1.02; 95% CI, 1.02-1.03), minimally invasive or robotic surgical approach (OR, 1.26; 95% CI, 1.23-1.29), adequate (≥12) lymph node assessment (OR, 3.46; 95% CI, 3.38-3.53), private insurance status (OR, 1.33; 95% CI, 1.26-1.40), Medicare insurance status (OR, 1.42; 95% CI, 1.35-1.49), and higher educational status (OR, 1.06; 95% CI, 1.02-1.09) were associated with higher odds of receiving NCCN-compliant care (all P values <.05). Overall, PCs contributed 36.5%, HCs contributed 1.3%, and OCs contributed 12.9% to the variation in guideline-compliant care, while SDoH contributed only 3.6% of the variation in receipt of NCCN-compliant care. CONCLUSION: The variation in NCCN-compliant care among patients with colon cancer was largely attributable to patient- and surgeon-level factors, whereas SDoH were associated with a smaller proportion of the variation.
RESUMO
BACKGROUND: There is limited data on the safety and efficacy of left atrial appendage occlusion (LAAO) devices in patients with cardiac amyloidosis. We examined the outcomes of patients with cardiac amyloidosis undergoing LAAO device implantation in a nationally representative cohort of patients. METHODS: The National Readmissions Database (NRD) was analyzed from 2016 to 2019 to identify patients ≥ 18 years old with atrial fibrillation (AF) undergoing LAAO. Patients were divided into those with cardiac amyloidosis and those without cardiac amyloidosis. A multivariable logistic regression model was utilized to assess the independent association of cardiac amyloidosis with in-hospital, 30-day/90-day/180-day outcomes after adjusting for confounders. RESULTS: Our cohort included 54,900 LAAO implantation procedures, of which 220 (0.4%) had cardiac amyloidosis. Patients with cardiac amyloidosis had a lower proportion of women and a lower prevalence of comorbidities including anemia, obesity, diabetes, and peripheral vascular disorders but a higher prevalence of stroke, as compared to those without cardiac amyloidosis. On multivariable analysis, cardiac amyloidosis was associated with significantly higher odds of peri-procedural major adverse events (adjusted odds ratio [aOR]: 2.69; 95% confidence interval [CI]: 1.41-5.14; p<0.01) and neurological complications (aOR: 5.48; 95% CI: 2.47-12.8; p<0.01). There was no difference in the odds of other peri-procedural complications, in-hospital mortality, hospital resource utilization, and 30/90/180-day all-cause/bleeding/stroke-related readmissions between both groups. CONCLUSION: Patients with cardiac amyloidosis undergoing LAAO device implantation have an increased risk of peri-procedural complications without any difference in bleeding/stroke-related readmissions. These hypothesis-generating findings need validation in future prospective studies.

BACKGROUND: Process-based quality metrics are important for improving long-term outcomes after surgical resection. We sought to develop a practical surgical quality score for patients diagnosed with pancreatic ductal adenocarcinoma undergoing curative-intent resection. METHODS: Patients who underwent surgical resection for pancreatic ductal adenocarcinoma between 2010 and 2017 were identified using the National Cancer Database. Five surgical quality metrics were defined: minimally invasive approach, adequate lymphadenectomy, negative surgical margins, receipt of adjuvant therapy, and no prolonged hospitalization. Log-rank test and multivariable Cox regression analysis were used to determine the association of quality metrics with overall survival. RESULTS: A total of 38,228 patients underwent curative-intent resection for pancreatic ductal adenocarcinoma. Median age at diagnosis was 68 years (interquartile range = 61-75), and roughly half the cohort was male (n = 19,562; 51.2%). Quality metrics were achieved on a varied basis: minimally invasive approach (n = 5,701; 14.9%), adequate lymphadenectomy (n = 27,122; 80.0%), negative surgical margin (n = 29,248; 76.5%), receipt of adjuvant therapy (n = 26,006; 68.0%), and absence of prolonged hospitalization (n = 26,470; 69.2%). An integer-based surgical quality score from 0 (no quality metrics) to 16 (all quality metrics) was calculated. Patients with higher scores had progressively better overall survival. Median overall survival differed substantially among the score categories (score = 0-4 points, 8.7 [8.0-9.6] months; 5-8 points, 17.5 [16.9-18.2] months; 9-12 points, 22.1 [21.6-22.8] months; and 13-16 points, 30.8 [30.2-31.3] months; P < .001). On multivariable analysis, risk-adjusted mortality hazards decreased in a stepwise manner with higher scores (0-4 points: reference; 5-8 points: multivariable adjusted hazard ratio = 0.60; 95% CI, 0.57-0.63; 9-12 points: adjusted hazard ratio = 0.49; 95% CI, 0.47-0.52; 13-16 points: and adjusted hazard ratio = 0.37; 95% CI, 0.34-0.40; all P < .001). CONCLUSION: Adherence to quality metrics may be associated with improved overall survival. Efforts aimed at increasing compliance with quality metric measures may help optimize long-term outcomes among patients undergoing surgical resection for pancreatic ductal adenocarcinoma.

OBJECTIVE: We sought to characterize postoperative outcomes among patients who underwent an oncologic operation relative to whether the treating surgeon was an international medical graduate (IMG) versus a United States medical graduate (USMG). SUMMARY BACKGROUND DATA: IMGs comprise approximately one-quarter of the physician workforce in the United States. METHODS: The 100% Medicare Standard Analytic Files were utilized to extract data on patients with breast, lung, hepato-pancreato-biliary (HPB), and colorectal cancer who underwent surgical resection between 2014 and 2020. Entropy balancing (EB) and multivariable regression analysis were performed to evaluate the association between postoperative outcomes among USMG and IMG surgeons. RESULTS: Among 285,930 beneficiaries, 242,914 (85.0%) and 43,016 (15.0%) underwent surgery by a USMG and IMG surgeon, respectively. Overall, 129,576 (45.3%) individuals were male, and 168,848 (59.1%) patients had a Charlson Comorbidity Index score >2. Notably, IMG surgeons were more likely to care for racial/ethnic minority patients (14.7% vs. 12.5%) and those with a high social vulnerability index (33.3% vs. 32.1%) (all P<0.001). On multivariable analysis after EB, patients treated by an IMG surgeon were less likely to experience adverse postoperative outcomes including 90-day readmission (OR 0.89, 95%CI 0.80-0.99) and index complications (OR 0.84, 95%CI 0.74-0.95) versus USMG surgeons (all P<0.05). Patients treated by IMG versus USMG surgeons had no difference in likelihood to achieve a textbook outcome (OR 1.10, 95%CI 0.99-1.21; P=0.077). CONCLUSIONS: Postoperative outcomes among patients treated by IMG surgeons were roughly equivalent to those of USMG surgeons. In addition, IMG surgeons were more likely to care for patients with multiple comorbidities and individuals from vulnerable communities.
RESUMO
BACKGROUND: We sought to examine the association between primary care physician (PCP) follow-up on readmission following gastrointestinal (GI) cancer surgery. METHODS: Patients who underwent surgery for GI cancer were identified using the Surveillance, Epidemiology and End Results (SEER) database. Multivariable regression was performed to examine the association between early PCP follow-up and hospital readmission. RESULTS: Among 60 957 patients who underwent GI cancer surgery, 19 661 (32.7%) visited a PCP within 30-days after discharge. Of note, patients who visited PCP were less likely to be readmitted within 90 days (PCP visit: 17.4% vs. no PCP visit: 28.2%; p < 0.001). Median postsurgical expenditures were lower among patients who visited a PCP (PCP visit: $4116 [IQR: $670-$13 860] vs. no PCP visit: $6700 [IQR: $870-$21 301]; p < 0.001). On multivariable analysis, PCP follow-up was associated with lower odds of 90-day readmission (OR: 0.52, 95% CI: 0.50-0.55) (both p < 0.001). Moreover, patients who followed up with a PCP had lower risk of death at 90-days (HR: 0.50, 95% CI: 0.40-0.51; p < 0.001). CONCLUSION: PCP follow-up was associated with a reduced risk of readmission and mortality following GI cancer surgery. Care coordination across in-hospital and community-based health platforms is critical to achieve optimal outcomes for patients.

BACKGROUND: New persistent opioid use (NPOU) after surgery has been identified as a common complication. This study sought to assess the long-term health outcomes among patients who experienced NPOU after gastrointestinal (GI) cancer surgery. METHODS: Patients who underwent surgery for hepato-pancreato-biliary and colorectal cancer between 2007 and 2019 were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database. Mixed-effect multivariable logistic regression and Cox proportional hazard models were used to estimate the risk of mortality and hospital visits related to falls, respiratory events, or pain symptoms. RESULTS: Among 15,456 patients who underwent GI cancer surgery, 967(6.6%) experienced NPOU. Notably, the patients at risk for the development of NPOU were those with a history of substance abuse (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.14-1.84), moderate social vulnerability (OR, 1.26; 95% CI, 1.06-1.50), an advanced disease stage (OR, 4.42; 95% CI, 3.51-5.82), or perioperative opioid use (OR, 3.07; 95% CI, 2.59-3.63. After control for competing risk factors, patients who experienced NPOU were more likely to visit a hospital for falls, respiratory events, or pain symptoms (OR, 1.45, 95% CI 1.18-1.78). Moreover, patients who experienced NPOU had a greater risk of death at 1 year (hazard ratio [HR], 2.15; 95% CI, 1.74-2.66). CONCLUSION: Approximately 1 in 15 patients experienced NPOU after GI cancer surgery. NPOU was associated with an increased risk of subsequent hospital visits and higher mortality. Targeted interventions for individuals at higher risk for NPOU after surgery should be used to help mitigate the harmful effects of NPOU.

BACKGROUND: We sought to assess healthcare utilization and expenditures among patients who developed venous thromboembolism (VTE) after gastrointestinal cancer surgery. METHODS: Patients who underwent surgery for esophageal, gastric, hepatic, biliary duct, pancreatic, and colorectal cancer between 2013 and 2020 were identified using the MarketScan database. Entropy balancing was performed to obtain a cohort that was well balanced relative to different clinical covariates. Generalized linear models were used to compare 1-year postdischarge costs among patients who did and did not develop a postoperative VTE. RESULTS: Among 20,253 individuals in the analytical cohort (esophagus [n = 518 {2.6%}], stomach [n = 970 {4.8%}], liver [n = 608 {3.0%}], bile duct [n = 294 {1.5%}], pancreas [n = 1511 {7.5%}], colon [n = 12,222 {60.3%}], and rectum [n = 4130 {20.4%}]), 894 (4.4%) developed VTE. Overall, most patients were male (n = 10,656 [52.6%]), aged between 55 and 64 years (n = 10,372 [51.2%]), and were employed full time (n = 11,408 [56.3%]). On multivariable analysis, VTE was associated with higher inpatient (mean difference [MD], $17,547; 95% CI, $15,141-$19,952), outpatient (MD, $8769; 95% CI, $7045-$10,491), and pharmacy (MD, $2811; 95% CI, $2509-$3113) expenditures (all P < .001). Furthermore, patients who developed VTE had higher out-of-pocket costs for inpatient (MD, $159; 95% CI, $66-$253) and pharmacy (MD, $122; 95% CI, $109-$136) services (all P < .001). CONCLUSION: Among privately insured patients aged <65 years, VTE was associated with increased healthcare utilization and expenditures during the first year after discharge.

BACKGROUND: This study aimed to characterize the association of preoperative acute cholangitis (PAC) with surgical outcomes and healthcare costs. METHODS: Patients who underwent pancreaticoduodenectomy (PD) between 2013 and 2021 were identified using 100% Medicare Standard Analytic Files. PAC was defined as the occurrence of at least 1 episode of acute cholangitis within the year preceding surgery. Multivariable regression analyses were used to compare postoperative outcomes and costs relative to PAC. RESULTS: Among 23,455 Medicare beneficiaries who underwent PD, 2,217 patients (9.5%) had at least 1 episode of PAC. Most patients (n = 14,729 [62.8%]) underwent PD for a malignant indication. On multivariable analyses, PAC was associated with elevated odds of surgical site infection (odds ratio [OR], 1.14; 95% CI, 1.01-1.29), sepsis (OR, 1.17; 95% CI, 1.01-1.37), extended length of stay (OR, 1.13; 95% CI, 1.01-1.26), and readmission within 90 days (OR, 1.14; 95% CI, 1.04-1.26). Patients with a history of PAC before PD had a reduced likelihood of achieving a postoperative textbook outcome (OR, 0.83; 95% CI, 0.75-0.92) along with 87.8% and 18.4% higher associated preoperative and postoperative healthcare costs, respectively (all P < .001). Overall costs increased substantially among patients with more than 1 PAC episode ($59,893 [95% CI, $57,827-$61,959] for no episode vs $77,922 [95% CI, $73,854-$81,990] for 1 episode vs $101,205 [95% CI, $94,871-$107,539] for multiple episodes). CONCLUSION: Approximately 1 in 10 patients undergoing PD experienced an antecedent PAC episode, which was associated with adverse surgical outcomes and greater healthcare expenditures.

BACKGROUND: Health care providers play a crucial role in increasing overall awareness, screening, and treatment of cancer, leading to reduced cancer mortality. We sought to characterize the impact of provider density on colorectal cancer population-level mortality. METHODS: County-level provider data, obtained from the Area Health Resource File between 2016 and 2018, were used to calculate provider density per county. These data were merged with county-level colorectal cancer mortality 2016-2020 data from the Centers for Disease Control and Prevention. Multivariable regression was performed to define the association between provider density and colorectal cancer mortality. RESULTS: Among 2,863 counties included in the analytic cohort, 1,132 (39.5%) and 1,731 (60.5%) counties were categorized as urban and rural, respectively. The colorectal cancer-related crude mortality rate was higher in counties with low provider density versus counties with moderate or high provider density (low = 22.9, moderate = 21.6, high = 19.3 per 100,000 individuals; P < .001). On multivariable analysis, the odds of colorectal cancer mortality were lower in counties with moderate and high provider density versus counties with low provider density (moderate odds ratio 0.97, 95% confidence interval 0.94-0.99; high odds ratio 0.88, 95% confidence interval 0.86-0.91). High provider density remained associated with a lower likelihood of colorectal cancer mortality independent of social vulnerability index (low social vulnerability index and high provider density: odds ratio 0.85, 95% confidence interval 0.81-0.89; high social vulnerability index and high provider density: odds ratio 0.93, 95% confidence interval 0.89-0.98). CONCLUSION: Regardless of social vulnerability index, high county-level provider density was associated with lower colorectal cancer-related mortality. Efforts to increase access to health care providers may improve health care equity, as well as long-term cancer outcomes.
