Background This study aimed to assess the relationship between availability of round-the-clock (RTC) in-house intensivists and patient outcomes in people who underwent surgery for a life-threatening emergency general surgery (LT-EGS) disease such as necrotizing soft-tissue infection, ischemic enteritis, perforated viscus, and toxic colitis. Methods Data on hospital-level critical care structures and processes from a 2015 survey of 2,811 US hospitals were linked to patient-level data from 17 State Inpatient Databases. Patients who were admitted with a primary diagnosis code for an LT-EGS disease of interest and underwent surgery on date of admission were included in analyses. Results We identified 3,620 unique LT-EGS admissions at 368 hospitals. At 66% (n = 243) of hospitals, 83.5% (n = 3,021) of patients were treated at hospitals with RTC intensivist-led care. These facilities were more likely to have in-house respiratory therapists and protocols to ensure availability of blood products or adherence to Surviving Sepsis Guidelines. When accounting for other key factors including overnight surgeon availability, perioperative staffing, and annual emergency general surgery case volume, not having a protocol to ensure adherence to Surviving Sepsis Guidelines (adjusted odds ratio, 2.10; 95% confidence interval, 1.12-3.94) was associated with increased odds of mortality. Conclusion Our results suggest that focused treatment of sepsis along with surgical source control, rather than RTC intensivist presence, is key feature of optimizing EGS patient outcomes. Level of evidence Therapeutic, level III.

Background Mental illness and depression can be associated with increased risk of suicidal ideation (SI). We sought to determine the association between mental illness and SI among cancer surgical patients. Methods Medicare beneficiaries who underwent resection of lung, esophageal, pancreatic, colon, or rectal cancer were analyzed. Patients were categorized as no mental illness, anxiety and/or depression disorders or bipolar/schizophrenic disorders. Results Among 211,092 Medicare beneficiaries who underwent surgery for cancer, the rate of suicidal ideation was 270/100,000 patients. Antecedent mental health diagnosis resulted in a marked increased SI. On multivariable analysis, patients with anxiety alone (OR 1.49, 95%CI 1.04–2.14), depression alone (OR 2.60, 95%CI 1.92–3.38), anxiety + depression (OR 4.50, 95%CI 3.48–5.86), and bipolar/schizophrenia (OR 7.30, 95%CI 5.27–10.30) had increased odds of SI. Conclusions Roughly 1 in 370 Medicare beneficiaries with cancer who underwent a wide range of surgical procedures had SI. An antecedent mental health diagnosis was a strong risk factor for SI.

Pancreatic diseases have long been associated with impaired glucose control. This study sought to identify the incidence of new insulin-dependent diabetes mellitus (IDDM) after pancreatectomy and the predictive accuracy of hemoglobin A1c (HbA1c) or blood glucose. Patients who underwent partial pancreatectomy and had preoperative HbA1c available at two academic institutions were assessed for new IDDM on discharge in relation to complication rates and survival. Of the 267 patients analyzed, 67% had abnormal HbA1c levels prior to surgery (mean 6.8%, glucose 135 mg/dL). Two hundred eight (77.9%) were not insulin-dependent prior to surgery, and 35 (16.8%) developed new IDDM after resection. On multivariable regression, increasing HbA1c and preoperative glucose were the only significant predictors for new IDDM. Optimal predictive cutoffs (HbA1c of 6.25% and glucose of 121 mg/dL) were determined in a discovery group (n = 143) and confirmed in a validation group (n = 124) with a diagnostic sensitivity of 72.7% and specificity of 84.8%. Patients with new IDDM after resection had higher rates of severe complications (OR 3.39), increased TPN at discharge (OR 4.32), and increased rates of discharge to nursing facilities (OR 2.57) (all P < 0.05). New IDDM was also associated with a decreased cancer-specific survival. Preoperative HbA1c ≥ 6.25% and blood glucose ≥ 121 mg/dL can accurately identify patients at increased risk of IDDM. These diagnostics may help identify patients in a preoperative setting that may benefit from interventions such as diabetes education or enhanced glucose control preoperatively.

Introduction: While tumor burden (TB) has been associated with outcomes among patients with hepatocellular carcinoma, the role of overall TB in intrahepatic cholangiocarcinoma (ICC) remains poorly defined. Methods: Patients undergoing curative-intent resection of ICC between 2000 and 2017 were identified from a multi-institutional database. The impact of TB on overall (OS) and disease-free survival (DFS) was evaluated in the multi-institutional database and validated externally. Results: Among 1101 patients who underwent curative-intent resection of ICC, 624 (56.7%) had low TB, 346 (31.4%) medium TB, and 131 (11.9%) high TB. OS incrementally worsened with higher TB (5-year OS; low TB: 48.3% vs medium TB: 29.8% vs high TB: 17.3%, p < 0.001). Similarly, patients with low TB had better DFS compared with medium and high TB patients (5-year DFS: 38.3% vs 18.7% vs 6.9%, p < 0.001). On multivariable analysis, TB was independently associated with OS (medium TB: HR = 1.40, 95% CI 1.14-1.71; high TB: HR = 1.89, 95% CI 1.46-2.45) and DFS (medium TB, HR = 1.61, 95% CI 1.33-1.96; high TB: HR = 2.03, 95% CI 1.56-2.64). Survival analysis revealed an excellent prognostic discrimination using the TB among the external validation cohort (3-year OS; low TB: 44.8%, medium TB: 29.3%; high TB: 23.3%, p = 0.03; 3-year DFS: low TB: 32.7%, medium TB: 10.7%; high TB: 0%, p < 0.001). While neoadjuvant chemotherapy was not associated with survival across the TB groups, receipt of adjuvant chemotherapy was associated with increased survival among patients with high TB (5-year OS: 24.4% vs 13.4%, p = 0.02). Conclusion: Overall TB dictated prognosis among patients with resectable ICC. TB may be used as a tool to help guide post-resection treatment strategies. info:eu-repo/semantics/publishedVersion

We sought to determine the impact of payer-mix on post-operative outcomes among Medicare beneficiaries following hepatopancreatic surgery.Medicare beneficiaries who underwent hepatopancreatic surgery were identified. Hospital quality markers were obtained from the Hospital General Information dataset. Hospitals were dichotomized (low/average vs. high) based on Medicare patient days versus all patient days irrespective of payer type.High Medicare patient-mix hospitals were more likely to be ranked higher than the national average relative to safety of care (29.4% vs. 38.1%) and timeliness of care (15.4% vs. 26.3%) versus low burden Medicare hospitals (both p 0.001). However, Medicare beneficiaries who had hepatopancreatic surgery at a high Medicare patient-mix hospital were at higher risk of a complication (OR = 1.13, 95%CI 1.04-1.22), and death within 30-days (OR = 1.37, 95%CI 1.23-1.53) following surgery.While hospitals caring for higher numbers of Medicare beneficiaries generally performed better on CMS quality indicators, these rankings did not equate to improved post-operative outcomes.

Background: Machine learning to predict morbidity and mortality—especially in a population traditionally considered low risk—has not been previously examined. We sought to characterize the incidence of death among patients with a low estimated morbidity and mortality risk based on the National Surgical Quality Improvement Program (NSQIP) estimated probability (EP), as well as develop a machine learning model to identify individuals at risk for “unpredicted death” (UD) among patients undergoing hepatopancreatic (HP) procedures. Methods: The NSQIP database was used to identify patients who underwent elective HP surgery between 2012–2017. The risk of morbidity and mortality was stratified into three tiers (low, intermediate, or high estimated) using a k-means clustering method with bin sorting. A machine learning classification tree and multivariable regression analyses were used to predict 30-day mortality with a 10-fold cross validation. C statistics were used to compare model performance. Results: Among 63,507 patients who underwent an HP procedure, median patient age was 63 (IQR: 54–71) years. Patients underwent either pancreatectomy (n=38,209, 60.2%) or hepatic resection (n=25,298, 39.8%). Patients were stratified into three tiers of predicted morbidity and mortality risk based on the NSQIP EP: low (n=36,923, 58.1%), intermediate (n=23,609, 37.2%) and high risk (n=2,975, 4.7%). Among 36,923 patients with low estimated risk of morbidity and mortality, 237 patients (0.6%) experienced a UD. According to the classification tree analysis, age was the most important factor to predict UD (importance 16.9) followed by preoperative albumin level (importance: 10.8), disseminated cancer (importance: 6.5), preoperative platelet count (importance: 6.5), and sex (importance 5.9). Among patients deemed to be low risk, the c-statistic for the machine learning derived prediction model was 0.807 compared with an AUC of only 0.662 for the NSQIP EP. Conclusions: A prognostic model derived using machine learning methodology performed better than the NSQIP EP in predicting 30-day UD among low risk patients undergoing HP surgery.

The objective of this study was to analyze whether primary tumor resection (PTR) among patients with stage IV gastrointestinal neuroendocrine tumor (GI-NET) and unresected metastases was associated with improved outcomes. Patients diagnosed with stage IV GI-NETs were identified in the linked SEER-Medicare database from 2004 to 2015. Overall survival (OS) of patients who did versus did not undergo PTR was examined using bivariate and multivariable cox regression analysis as well as propensity score matching (PSM). Among 2219 patients with metastatic GI-NETs, 632 (28.5%) underwent PTR, whereas 1587 (71.5%) did not. The majority of individuals had a NET in the pancreas (n = 969, 43.6%); the most common site of metastatic disease was the liver (n = 1064, 47.9%). Patients with stage IV small intestinal NETs most frequently underwent PTR (62.6%) followed by individuals with colon NETs (56.5%). After adjusting for all competing factors, PTR remained independently associated with improved OS (HR = 0.65, 95% CI: 0.56–0.76). Following PSM (n = 236 per group), patients who underwent PTR had improved OS (median OS: 1.3 years vs 0.8 years, p = 0.016). While PTR of NETs originating from stomach, small intestine, colon, and pancreas was associated with improved OS, PTR of rectal NET did not yield a survival benefit. Primary GI-NET resection was associated with a survival benefit among individuals presenting with metastatic GI-NET with unresected metastases. Resection of primary GI-NET among patients with stage IV disease and unresected metastases should only be performed in selected cases following multi-disciplinary evaluation.

OBJECTIVE We sought to characterize the association between patient county-level vulnerability with postoperative outcomes. SUMMARY BACKGROUND DATA Although the impact of demographic-, clinical- and hospital-level factors on outcomes following surgery have been examined, little is known about the effect of a patient's community of residence on surgical outcomes. METHODS Individuals who underwent colon resection, coronary artery bypass graft (CABG), lung resection, or lower extremity joint replacement (LEJR) were identified in the 2016 to 2017 Medicare database, which was merged with Center for Disease Control social vulnerability index (SVI) dataset at the beneficiary level of residence. Logistic regression models were utilized to estimate the probability of postoperative complications, mortality, readmission, and expenditures. RESULTS Among 299,583 Medicare beneficiary beneficiaries who underwent a colectomy (n = 88,778, 29.6%), CABG (n = 109,564, 36.6%), lung resection (n = 30,401, 10.1%), or LEJR (n = 70,840, 23.6%).Mean SVI score was 50.2 (standard deviation: (25.2); minority patients were more likely to reside in highly vulnerable communities (low SVI: n = 3531, 5.8% vs high SVI: n = 7895, 13.3%; P 0.05). CONCLUSIONS Patients residing in vulnerable communities characterized by a high SVI generally had worse postoperative outcomes. The impact of social vulnerability was most pronounced among Black/minority patients, rather than White individuals. Efforts to ensure equitable surgical outcomes need to focus on both patient-level, as well as community-specific factors.

OBJECTIVE: The objective of the current study was to define surgical outcomes after resection of multinodular hepatocellular carcinoma (HCC) beyond the Milan criteria, and develop a prediction tool to identify which patients likely benefit the most from resection. BACKGROUND: Liver resection for multinodular HCC, especially beyond the Milan criteria, remains controversial. Rigorous selection of the best candidates for resection is essential to achieve optimal outcomes after liver resection of advanced tumors. METHODS: Patients who underwent resection for HCC between 2000 and 2017 were identified from an international multi-institutional database. Patients were categorized according to Milan criteria status. Pre- and postoperative overall survival (OS) prediction models that included HCC tumor burden score (TBS) among patients with multinodular HCC beyond Milan criteria were developed and validated. RESULTS: Among 1037 patients who underwent resection for HCC, 164 (15.8%) had multinodular HCC beyond the Milan criteria. Among patients with multinodular HCC, 25 (15.2%) patients experienced a serious complication and 90-day mortality was 3.7% (n = 6). Five-year OS after resection of multinodular HCC beyond Milan criteria was 52.8%. A preoperative TBS-based model (5-year OS: low-risk, 73.7% vs intermediate-risk, 45.1% vs high-risk, 13.1%), and postoperative TBS-based model (5-year OS: low-risk, 80.1% vs intermediate-risk, 37.2% vs high-risk, not reached) categorized patients into distinct prognostic groups relative to long-term prognosis (both P < 0.001). Pre- and postoperative models could accurately stratify OS in an external validation cohort (5-year OS; low vs medium vs high risk; pre: 66.3% vs 25.2% vs not reached, P = 0.012; post: 61.4% vs 42.5% vs not reached, P = 0.045) Predictive accuracy of the pre- and postoperative models was good in the training (c-index; pre: 0.68; post: 0.71), internal validation (n = 2000 resamples) (c-index, pre: 0.70; post: 0.72) and external validation (c-index, pre: 0.67; post 0.68) datasets. TBS alone could stratify patients relative to 5-year OS after resection of multinodular HCC beyond Milan criteria (c-index: 0.65; 5-year OS; low TBS: 70.2% vs medium TBS: 54.7% vs high TBS: 16.7%; P < 0.001). The vast majority of patients with low and intermediate TBS were deemed low or medium risk based on both the preoperative (98.4%) and postoperative risk scores (95.3%). CONCLUSION: Prognosis of patients with multinodular HCC was largely dependent on overall tumor burden. Liver resection should be considered among patients with multinodular HCC beyond the Milan criteria who have a low- or intermediate-TBS.

Geographic variations in access to care exist in the USA. We sought to characterize county-level disparities relative to access to surgery among patients with early-stage hepatopancreatic (HP) cancer. Data were extracted from the Surveillance, Epidemiology, and End Results (SEER)-Medicare Linked database from 2004 to 2015 to identify patients undergoing surgery for early-stage HP cancer . County-level information was acquired from the Area Health Resources Files (AHRF). Multivariable logistic regression analysis was performed to assess factors associated with utilization of HP surgery on the county level. Among 13,639 patients who met inclusion criteria, 66.9% (n = 9125) were diagnosed with pancreatic cancer and 33.1% (n = 4514) of patients had liver cancer. Among patients diagnosed with early-stage liver and pancreas malignancy, two-thirds (n = 8878, 65%) underwent surgery. Marked county-level variation in the utilization of surgery was noted among patients with early-stage HP cancer ranging from 57.1% to more than 83.3% depending on which county a patient resided. After controlling for patient and tumor-related characteristics, counties with the highest quartile of patients living below the poverty level had 35% lower odds of receiving surgery for early stage HP cancer compared patients who lived in a county with the lowest proportion of patients below the poverty line (OR 0.65, 95% CI 0.55–0.77). In addition, patients residing in counties with the highest surgeon-to-population ratio (OR 2.01, 95% CI 1.52–2.65), as well as the highest hospital bed-to-population ratio (OR 1.29, 95% CI 1.07–1.54), were more likely to undergo surgical treatment for an early-stage HP malignancy. Area-level variations among patients undergoing surgery for early-stage HP cancer were mainly due to differences in structural measures and county-level factors. Policies targeting high-poverty counties and improvement in structural measures may reduce variations in utilization of surgery among patients diagnosed with early-stage HP cancer.

Background: Composite measures such as "Textbook Outcome" (TO) may be superior to individual quality metrics to assess surgical care and hospital performance. However, the incidence and factors associated with TO after resection of HCC remain poorly defined. Methods: Hospital variation in the rates of TO, factors associated with achieving a TO and the impact of TO on long-term survival following resection for HCC were examined using an international multi-institutional database. Results: Among 605 patients who underwent curative-intent resection of HCC, the unadjusted incidence of TO ranged from 50.9% to 77.7%. While achievement of each individual quality metric was relatively high (range, 74.5-98.0%), an overall TO was achieved among only 62.3% (n = 377) of patients. At the hospital level, TO ranged from 54.3% to 72.9%. Patients with BCLC-0 HCC (referent BCLC-B/C; OR: 4.17, 95%CI: 1.62-10.7) and ALBI grade 1 (referent ALBI grade 2/3; OR: 1.49, 95%CI: 1.06-2.11) had higher odds of achieving a TO. On multivariable analysis, TO was associated with improved overall survival (HR: 0.60, 95% CI: 0.42-0.85). Conclusion: Roughly 6 in 10 patients achieved a TO following resection for HCC. When achieved, TO was associated with better long-term outcomes. TO is a simple composite measure of both short- and long-term outcomes among patients undergoing resection for HCC. info:eu-repo/semantics/publishedVersion

Although KRAS mutation status is known to affect the prognosis of patients with colorectal liver metastasis, the hierarchical association between other prognostic factors and KRAS status is not fully understood.Patients who underwent a hepatectomy for colorectal liver metastasis were identified in a multi-institutional international database. A classification and regression tree model was constructed to investigate the hierarchical association between prognostic factors and overall survival relative to KRAS status.Among 1,123 patients, 29.9% (n = 336) had a KRAS mutation. Among wtKRAS patients, the classification and regression tree model identified presence of metastatic lymph nodes as the most important prognostic factor, whereas among mtKRAS patients, carcinoembryonic antigen level was identified as the most important prognostic factor. Among patients with wtKRAS, the highest 5-year overall survival (68.5%) was noted among patients with node negative primary colorectal cancer, solitary colorectal liver metastases, size4.3 cm. In contrast, among patients with mtKRAS colorectal liver metastases, the highest 5-year overall survival (57.5%) was observed among patients with carcinoembryonic antigen6 mg/mL. The classification and regression tree model had higher prognostic accuracy than the Fong score (wtKRAS [Akaike's Information Criterion]: classification and regression tree model 3334 vs Fong score 3341; mtKRAS [Akaike's Information Criterion]: classification and regression tree model 1356 vs Fong score 1396).Machine learning methodology outperformed the traditional Fong clinical risk score and identified different factors, based on KRAS mutational status, as predictors of long-term prognosis.

Purpose: To assess the rate of and characterize the utilization of pastoral care (PC) among patients on their cancer treatment trajectory. Methods: Patients included in the present study were diagnosed with cancer 01/2015-08/2019 at The Ohio State Wexner Medical Center—The James. To determine which patient demographic and clinical factors were independently associated with PC utilization, a multivariable logistic regression was performed. Results: A total of 14,322 patients were included in the study and 5,166 (36.1%) had at least one visit with PC. Cancers such as brain (n = 232, 4.5% vs. n = 159, 1.7%), liver/pancreas (n = 733, 14.2% vs. 686, 7.5%), and lung (n = 1,288 vs. 24.9% vs. n = 1,113, 12.2%) were more commonly noted among patients who utilized PC services (all p < 0.001). Furthermore, compared with patients diagnosed with Stage 1 cancer, patients with more advanced disease stages had higher odds of utilizing PC services (Stage III: OR 2.37, 95% CI 2.07-2.70; Stage IV OR 2.31, 95% CI: 2.04-2.61; both p < 0.05). Interestingly, patients who had a DNR order had a markedly higher odds (OR 4.18, 95%CI 3.76-4.65, p < 0.001) of utilizing PC services. Discussion: One in three patients with cancer utilized PC services. Patients with more severe prognoses and individuals with a DNR order were more likely to utilize PC. The data suggest that PC services are an important resource for many patients and should be integrated into the treatment approach for cancer.

A person’s community, or lived environment, may play an important role in achieving optimal health outcomes. The objective of the current study was to assess the association of county-level vulnerability with the probability of having a non-elective colon resection. We hypothesized that individuals from areas with a high social vulnerability would be at greater risk of non-elective colon resection compared with patients from low social vulnerability areas. Patients aged 65–99 who underwent a colon resection for a primary diagnosis of either diverticulitis (n = 11,812) or colon cancer (n = 33,312) were identified in Medicare Part A and Part B for years 2016–2017. Logistic regression analysis was used to evaluate differences in probability of undergoing an elective versus non-elective operation from counties relative to county-level social vulnerability index (SVI). Secondary outcomes included postoperative complications, mortality, readmission, and index hospitalization expenditure. Among 45,124 patients, 11,812 (26.2%) underwent a colon resection for diverticulitis, while 33,312 (73.8%) had a resection for colon cancer; 31,012 (68.7%) patients had an elective procedure (diverticulitis n = 7291 (61.7%) vs. cancer n = 23,721 (71.2%)), while 14,112 (31.3%) had an emergent operation (diverticulitis n = 4521 (38.3%) vs. cancer n = 9591 (28.8%)). Patients with a high SVI were more likely to undergo an emergent colon operation compared with low SVI patients (43.7% vs. 40.4%) (p < 0.001). The association of high SVI with increased risk of an emergent colon operation was similar among patients with diverticulitis (emergent: low SVI 37.2% vs. high SVI 40.4%) or colon cancer (emergent: low SVI 26.0% vs. high SVI 29.9%) (both p < 0.05). On multivariable analyses, risk-adjusted probability of undergoing an urgent/emergent operation remained associated with SVI (p < 0.05). Patients residing in vulnerable communities characterized by a high SVI were more likely to undergo a non-elective colon resection for either diverticulitis or colon cancer. Patients from high SVI areas had a higher risk of postoperative complications, as well as index hospitalization expenditures; however, there were no differences in mortality or readmission rates.

Traditional metrics may inadequately represent rates of attaining optimal oncologic care. We evaluated a composite “textbook oncologic outcome” (TOO) to assess the incidence of achieving an “optimal” clinical result after colon adenocarcinoma (CA) resection. The National Cancer Database (NCDB) was queried to identify patients undergoing colectomy for non-metastatic CA between 2010 and 2015. TOO was defined as a margin negative resection with an AJCC compliant lymph node evaluation, no prolonged length of stay (LOS) or 30-day readmission/mortality, as well as receipt of stage appropriate adjuvant chemotherapy. Among 170,120 patients who underwent colectomy at 1315 hospitals, 93,204 (54.8%) achieved TOO with large variations observed among facilities. While certain factors were achieved nearly universally (R0 margin, 95.6%; no 30-day mortality, 97.2%), avoidance of prolonged LOS (77.3%) and appropriate adjuvant chemotherapy (83.0%) were achieved less consistently. On multivariable analysis, Black race/ethnicity (OR 0.82, 95% CI 0.80–0.85), Medicaid insurance (OR 0.64, 0.61–0.68), and low-volume facility (< 50/year) (OR 0.83, 0.77–0.89) were associated with decreased likelihood of TOO. Achievement of TOO was associated with improved long-term survival (HR 0.45; 95% CI 0.44–0.46). Roughly one-half of patients undergoing resection of CA achieved an optimal clinical outcome. TOO may be a more useful quality metric to assess patient-centric composite outcomes following surgical procedures.

Background Although most conventional risk prediction models have been based on preoperative information, intra- and post-operative events may be more relevant to mortality after surgery. We sought to develop a mortality risk calculator based on real time characteristics associated with hepatectomy. Methods Patients who underwent hepatectomy between 2014 and 2017 were identified in the ACS-NSQIP dataset. Three prediction models (pre-, intra-, post-operative) were developed and validated using perioperative data. Results Among 14,720 patients, 197 (1.3%) experienced 30-day mortality. The predictive ability of the real-time mortality risk calculator was very good based on only preoperative factors (AUC; training cohort: 0.813, validation cohort: 0.731). Incorporating intra-operative variables into the model increased the AUC (training: 0.838, validation: 0.777), while the post-operative model achieved an AUC of 0.922 in the training and 0.885 in the validation cohorts, respectively. While patients with low preoperative risk had only very small fluctuations in the estimated 30-day mortality risk during the intraoperative (Δ0.4%) and postoperative (Δ0.6%) phases, patients who were already deemed high risk preoperatively had additional increased mortality risk based on factors that occurred in the intraoperative (Δ5.4%) and postoperative (Δ9.3%) periods. Conclusion A real-time mortality risk calculator may better help clinicians identify patients at risk of death at the different stages of the surgical episode.

Background In response to duty hour restrictions, hospitals expanded residency programs and added advanced practice providers. We sought to determine if type of clinical support was associated with emergency general surgery outcomes. Methods As part of our 2015 survey of acute care hospitals, we asked hospitals whether residents and advanced practice providers participate in emergency general surgery care. Data from responding hospitals were linked to patient data (≥18 years old admitted with an emergency general surgery diagnosis) from 17 State Inpatient Databases using American Hospital Association identifiers. Analyses compared emergency general surgery patient and hospital characteristics based on type of providers assisting emergency general surgery surgeons (none, only advanced practice providers, only residents, or both). Multivariable analysis determined if presence of advanced practice providers and/or residents was associated with type of management, mortality, or complications. Results Eighty-three hospitals and 49,271 unique emergency general surgery admissions were included. Hospitals without residents and advanced practice providers were most likely to manage patients operatively. However, hospitals with residents (alone or with advanced practice providers) had reduced odds of systemic complication compared with hospitals without clinical support (adjusted odds ratio 0.77 [95% confidence interval 0.60–0.98] and adjusted odds ratio 0.77 [95% confidence interval 0.62–0.95], respectively), while hospitals with only residents had the lowest odds of operative complication. Conclusion Our findings highlight the positive effect residents (alone or partnering with advanced practice providers) can have on emergency general surgery patient outcomes.

A primary goal of the recent state and federal health reform is to increase access to care through expanded insurance coverage. We sought to evaluate the effect of Medicaid expansion (ME) on four high-risk cancer operations in California. The California Office of Statewide Health Planning database was used to identify patients who underwent either lung, esophageal, pancreas, or rectal resection for cancer between 2012 and 2016. To include only patients eligible for Medicaid and not Medicare, patients > 65 years were excluded. Trends in insurance coverage rates and utilization of high-volume hospitals were evaluated relative to the pre-policy (2012–2013) versus the post-policy (2014–2016) period. Overall 10,569 individuals (esophageal: 5.6%; lung: 38%; pancreas: 14.1%; rectal: 42.3%) underwent a cancer operation. Following ME, Medicaid coverage increased from 12.4 to 20.2% (p 0.05). Of note, following ME, there was an increase in probability of utilization of high-volume hospitals for lung (47.6% vs. 56.3%), rectal (74.0% vs. 77.7%), and pancreas (60.2% vs. 68.5%) (p 0.05). ME was associated with an increase in Medicaid coverage, which resulted in more beneficiaries undergoing cancer operations at high-volume hospitals. While ME was associated with increased access to care, peri-operative outcomes were comparable pre- versus post-ME implementation.

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

The current study aimed to define the relationship between patient satisfaction, hospital-level factors, and clinical outcomes among patients undergoing major surgery for cancer. The Medicare Inpatient Standard Analytic Files were used to identify patients undergoing lung, esophageal, colorectal, hepatic, or pancreatic surgery between 2016 and 2017, and Hospital Consumer Assessment of Healthcare Providers and Systems survey data were used to assess performance in terms of patient satisfaction. Among 60,446 patients, half were female (n = 31,244, 52%) with a median age of 73 years (interquartile range [IQR] 69–78 years). Patients who underwent surgery for esophageal resection (odds ratio [OR] 2.44; 95% confidence interval [CI] 1.10–5.40) and were Caucasian (OR 2.43; 95% CI 2.11–2.81) had optimal patient satisfaction. Hospital level factors such as urban location (OR 3.69; 95% CI 3.16–4.29), 200 + beds (OR 3.58; 95% CI 3.09–4.13), greater inpatient surgical volume (OR 3.03; 95% CI 2.82–3.25), higher nurse-to-bed ratio (OR 4.57; 95% CI 4.25–4.92), non-profit hospital status (OR 1.14; 95% CI 1.01–1.29), and non-teaching hospital status (OR 1.52; 95% CI 1.39–1.65) were related to optimal patient satisfaction. In adjusted analysis, patients undergoing surgery at hospitals reporting poor or average patient satisfaction had 22% higher odds of 90-day mortality than patients undergoing surgery at optimal-satisfaction hospitals (OR 1.22; 95% CI 1.09–1.36). In addition, hospitals with the highest patient satisfaction scores also had the highest proportion of surgical cases that achieved the composite textbook outcome (TO) quality metric (OR 1.12; 95% CI 1.05–1.20). Higher patient satisfaction was strongly associated with hospital structural measures such as bed number, urban location, nurse-to-bed ratio, and “optimal” TO after cancer surgery. These data highlight how high quality of care can directly lead to improved patient satisfaction among surgical patients with cancer.

Assessing composite measures of quality such as textbook outcome may be superior to focusing on individual parameters when evaluating hospital performance. The aim of the current study was to assess the impact of teaching hospital status on the occurrence of a textbook outcome after hepatopancreatic surgery.The Medicare Inpatient Standard Analytic Files were used to identify patients undergoing hepatopancreatic surgery from 2013 to 2015 for a malignant indication. Stratified and multivariable regression analyses were performed to determine the relationship between teaching hospital status, hospital surgical volume and textbook outcome.Among 8,035 Medicare patients (hepatectomy; 41.8%, pancreatectomy; 58.2%), 6,196 (77.1%) patients underwent surgery at a major teaching hospital, whereas 1,839 (22.9%) patients underwent surgery at a minor teaching hospital. Patients undergoing surgery for pancreatic cancer at a major teaching hospital had a greater likelihood of achieving a textbook outcome compared with patients treated at a minor teaching hospital (minor teaching hospital: 456, 40% versus major teaching hospital: 1,606, 45.4%; P = .002). The likelihood of textbook outcome was also greater among patients undergoing hepatopancreatic surgery at high-volume centers (pancreas, low volume: 875, 40.5% versus high volume: 1,187, 47.1% P.001; liver, low volume: 608, 41.8% versus high volume: 886, 46.6%; P = .005). When examining only major teaching hospitals, patients undergoing a pancreatectomy at a high-volume center had 29% greater odds of achieving a textbook outcome (odds ratio 1.29, 95% confidence interval 1.12-1.49). In contrast, among patients undergoing pancreatic resection at high-volume centers, the odds of achieving a textbook outcome was comparable among major versus minor teaching hospital (odds ratio 1.17, 95% confidence interval 0.89-1.53).The odds of achieving a textbook outcome after pancreatic and hepatic surgery was greater at major versus minor teaching hospitals; however, this effect was largely mediated by hepatopancreatic procedural volume. Patients and payers should focus on regionalization of pancreatic and liver resection to high-volume centers in an effort to optimize the chances of achieving a textbook outcome.

To characterize cancer care provider perceptions of the role of religion and spirituality (RS p = 0.02). All providers were equally as likely to believe that RS IQR 0.9–2.0) compared with physicians (median 1.0; IQR 0.9–2.0) or other providers (median 1.4; IQR 1.0–2.1) (p

We sought to characterize surgeon perceptions of patient attachment-related behaviors relative to patient-centered approaches during treatment decision-making within the clinical encounter. An online survey including clinical vignettes was sent to board-certified surgeons to assess their approach to patient-centered treatment decision-making. Within these vignettes, patient behaviors associated with attachment styles (secure vs 3 insecure subtypes: avoidant, anxious, and fearful) were fixed and patient factors (age, race, occupation, and gender) were randomized. Analysis included repeated measures mixed-effects linear regression. Among the 208 respondents, the majority were male (65.4%) and White/Caucasian (84.5%) with an average age of 51.6 years (SD = 9.9). Most surgeons had been in practice for more than 10 years (66.8%) and treated adult patients (77.4%). Surgical specializations included breast (27.2%), HPB (35.0%), and broad-based/general (21.8%). Patient race, age, and gender did not impact surgeons’ patient-centered approach to treatment decision-making (all ps > 0.05). However, when the “patient” had a white collar occupation and were securely attached, surgeons reported a greater likeliness to spend equal time presenting all treatment options (p = 0.02 and p < 0.001, respectively) and believe the patient wanted an active role in decision-making (p = 0.01 and p < 0.001, respectively). Surgeons reported being least likely to agree with a patient’s treatment decision (p < 0.001) and an increased likelihood of being directive (p = 0.002) when patients exhibited behaviors associated with avoidant attachment. Attachment-related behaviors were associated with differences in surgeon approaches to patient-centered decision-making. Attachment styles may offer a framework for providers to understand patient behaviors and needs, thereby providing insight on how to tailor their approach and provide optimal patient-centered care.

Background Gastrointestinal cancers contribute substantially to the cost of health care. We sought to quantify and compare the financial burden associated with treatment of gastrointestinal cancers versus other common nongastrointestinal cancers. Methods The Medical Expenditure Panel Survey from 2006 to 2015 was used to identify individuals with gastrointestinal cancer, other nongastrointestinal cancer (breast/prostate or lung), or no history of malignancy. Total and out-of-pocket medical expenditures were compared. Among each cohort, risk of high and catastrophic financial burden was determined. Results A total of 90,344 individuals were identified, which was extrapolated to a national representative sample of 95,449,062 individuals. Overall, an estimated 365,367 (0.4%) individuals had a gastrointestinal cancer while 2,015,724 (2.1%) had lung, breast, or prostate cancer. Mean adjusted total health expenditures was greater among patients with gastrointestinal cancer ($13,716; 95% confidence interval, $9,805–$17,628) versus patients with nongastrointestinal cancer ($8,665; 95% confidence interval, $8,222–$9,108) or individuals without cancer ($5,807; 95% confidence interval $5,740–$5,874). An estimated 15.8% (n = 57,898) and 7.1% (n = 25,956) of patients with gastrointestinal cancer experienced a high and catastrophic financial burden, respectively. Patients with gastrointestinal cancer had a 64% increased odds of experiencing catastrophic financial burden compared with patients without a history of cancer (odds ratio 1.64, 95% confidence interval, 1.17–2.31). Furthermore, patients with a gastrointestinal cancer had nearly 40% increased odds of high financial burden associated with their care compared with patients without cancer (odds ratio 1.37; 95% confidence interval, 1.00–1.88). Conclusion The risk of experiencing catastrophic financial burden among patients with gastrointestinal cancer was considerable, as roughly 1 in 7 patients experienced high financial burden, and 1 in 13 had a catastrophic financial burden.

Background The objective of the current study was to define and compare rates of textbook outcomes (TO) among patients undergoing colorectal, lung, esophagus, liver, and pancreatic surgery for cancer at U.S. News & World Report (USNWR) ranked hospitals. Methods Medicare Inpatient Standard Analytic Files 2013-2015 were utilized to examine the relationship of TO and USNWR hospital ratings following surgery for colorectal, lung, esophageal, pancreatic, and liver cancer. TO was defined as no postoperative surgical complications, no prolonged length of hospital stay, no readmission within 90 days after discharge, and no postoperative mortality within 90 days after surgery. Results Among the 35,352 Medicare patients included in the cohort, 16,820 (47.6%) underwent surgery at honor roll hospitals, whereas 18 532 (52.4%) underwent surgery at non-honor roll hospitals. The overall proportion of patients who achieved TO was 50.1%. In examining the clinical outcomes of patients who underwent surgery, there was no difference in the odds of achieving TO at honor roll vs non-honor roll hospitals (colorectal: odds ratio [OR], 0.87; 95% confidence interval [CI], 0.69-1.10; lung: OR, 1.07; 95% CI, 0.87-1.32; esophagus: OR, 1.44; 95% CI, 0.72-2.89; liver: OR, 1.27; 95% CI, 0.87-1.84; pancreas: OR, 1.04; 95% CI, 0.67-1.62). Conclusion and relevance Patients undergoing surgery for lung, esophageal, liver, pancreatic, and colorectal cancer had comparable rates of TO at honor roll vs non-honor roll hospitals. No linear association was observed between hospital position in the rank and postoperative outcomes such as TO indicating that patients should not overly focus on the exact position within USNWR ranked hospitals. These data highlight to patients and physicians that up to one-half of patients undergoing surgery for cancer should anticipate at least one adverse outcome.

BACKGROUND Composite outcomes may more accurately reflect patient and provider expectations around optimal care. We sought to determine the impact of achieving a so-called "textbook oncologic outcome" (TOO) among patients undergoing resection of pancreatic adenocarcinoma (PDAC). METHODS Patients undergoing pancreaticoduodenectomy (PD) for PDAC between 2006 and 2016 were identified in the National Cancer Database (NCDB). TOO was defined by: margin negative resection, compliant lymph node evaluation, no prolonged length-of-stay, no 30-day readmission/mortality, and receipt of adjuvant chemotherapy. Factors associated with TOO and overall survival (OS) were evaluated using multivariable logistic and Cox regression models, respectively. RESULTS Among 18 608 patients who underwent PD at 782 hospitals, many patients successfully achieved certain TOO factors such as R0 margin (77.9%) and no 30-day mortality (96.9%), while other TOO criteria such as receipt of adjuvant therapy (48.2%) were achieved less frequently. Overall, only 3124 (16.8%) patients achieved a TOO. Factors associated with lower odds of TOO included: older age, Black race, Medicaid insurance, Community facility, and low PD facility (

Although previous studies have suggested that drain management is highly variable, data on drain placement and timing of drain removal among patients undergoing hepatic resection remain scarce. The objective of the current study was to define the utilization of drain placement among patients undergoing major hepatic resection. The ACS NSQIP-targeted hepatectomy database was used to identify patients who underwent major hepatectomy between 2014 and 2017. Association between day of drain removal, timing of discharge, and drain fluid bilirubin on postoperative day (POD) 3 (DFB-3) was assessed. Propensity score matching (PSM) was used to compare outcomes of patients with a drain removed before and after POD 3. Among 5330 patients, most patients had an abdominal drain placed at the time of hepatic resection (n = 3075, 57.7%). Of 2495 patients with data on timing of drain removal, only 380 patients (15.2%) had their drain removed by POD 3. Almost 1 in 6 patients (n = 441, 17.7%) were discharged home with the drain in place. DFB-3 values correlated poorly with POD of drain removal (R2 = 0.0049). After PSM, early drain removal (≤ POD 3) was associated with lower rates of grade B or C bile leakage (2.1% vs. 7.1%, p = 0.008) and prolonged length of hospital stay (6.0% vs. 12.7%, p = 0.009) compared with delayed drain removal (> POD 3). Roughly 3 in 5 patients had a drain placed at the time of major hepatectomy and only 1 in 7 patients had the drain removed early. This study demonstrated the potential benefits of early drain removal in an effort to improve the quality of care following major hepatectomy.

Many patients who present for complex surgery have underlying medical comorbidities. While surgeons often refer these patients to medical appointments for preoperative “optimization” or “clearance,” the actual impact of these visits remains poorly examined. The objective of the current study was to define the potential benefit of preoperative medical appointments on outcomes and costs associated with hepatopancreatic (HP) surgery. Patients with modifiable comorbidities undergoing HP surgery were identified in the Medicare claims data. The association of preoperative non-surgical visit and postoperative outcomes and expenditures was assessed using inverse propensity treatment weighting analysis and multivariable logistic regression. Among the 5574 Medicare beneficiaries who underwent a hepatopancreatic surgery, one in seven patients (n = 830, 14.9%) was “optimized” preoperatively. On multivariable logistic regression analysis, age (OR 1.02; 95% CI 1.01–1.03; p = 0.006) and higher comorbidity burden (OR 1.03; 95% CI 1.01–1.05; p = 0.007) were associated with modest increased odds of being referred in the preoperative period for a non-surgical evaluation; the factor most associated with preoperative non-surgical visit was male patient sex (OR 1.33; 95% CI 1.14–1.56; p

BACKGROUND Historically, women have been largely underrepresented in the body of medical research. Given the paucity of data regarding race and trauma in women, we aimed to evaluate the most common types of traumas incurred by women and analyze temporal racial differences. METHODS A 10-year review (2007-2016) of the National Trauma Data Bank was conducted to identify common mechanisms of injuries among women. Trends of race, intent of injury, and firearm-related assaults were assessed using the Cochran-Armitage Trend test. Multivariable multinomial logistic regressions were utilized to examine the association between race and trauma subtypes. RESULTS Of the 2,082,768 women identified as a trauma during this study period, the majority presented due to an unintentional intent (94.5%), whereas fewer presented secondary to an assault (4.4%) or self-inflicted injury (1.1%). While racioethnic minority women encompassed a small percentage of total traumas (19%), they accounted for roughly three fifths of assault-related traumas (p < 0.001). Though total assaults decreased by 20.8% during the study period, black and Hispanic women saw a disproportionately smaller decrease of 15.1% and 15.8%, respectively. On regression analysis, compared with white women, black women had more than four times the odds of being an assault-related trauma compared with unintentional trauma (odds ratio, 4.48; 95% confidence interval, 4.41-4.55). On subset analysis, firearm-related assault was 17.3 times more prevalent among black women (white, 0.3% vs. black: 5.2%; p < 0.001). In fact, history of alcohol abuse was found to be an effect modifier of the association of race/ethnicity and firearm-related trauma. CONCLUSION Compelling data highlight a disproportionate trend in the assault-related trauma of minority women. Specifically, minority women, especially those with a history of alcohol abuse, were at increased risk of being involved in a firearm assault. Further studies are essential to help mitigate disparities and subsequently develop preventative services for this diverse population. LEVEL OF EVIDENCE Epidemiological, Level III.

Background: The objective of the current study was to assess the impact of serum CA19-9 and CEA and their combination on survival among patients undergoing surgery for intrahepatic cholangiocarcinoma (ICC). Methods: Patients who underwent curative-intent resection of ICC between 1990 and 2016 were identified using a multi-institutional database. Patients were categorized into four groups based on combinations of serum CA19-9 and CEA (low vs. high). Factors associated with 1-year mortality after hepatectomy were examined. Results: Among 588 patients, 5-year OS was considerably better among patients with low CA19-9/low CEA (54.5%) compared with low CA19-9/high CEA (14.6%), high CA19-9/low CEA (10.0%), or high CA19-9/high CEA (0%) (P < 0.001). No difference in 1-year OS existed between patients who had either high CA19-9 (high CA19-9/low CEA:70.4%) or high CEA levels (low CA19-9/high CEA:72.5%) (P = 0.92). Although patients with the most favorable tumor marker profile (low CA19-9/low CEA) had the best 1-year survival (87.9%), 15.1% (n = 39) still died within a year of surgery. Among patients with low CA19-9/low CEA, a high neutrophil-to-lymphocyte ratio (NLR) (odds ratio 1.09; 95% confidence interval 1.03-1.64) and large size tumor (odds ratio 3.34; 95% confidence interval 1.40–8.10) were associated with 1-year mortality (P < 0.05). Conclusions: Patients with either a high CA19-9 and/or high CEA had poor 1-year survival. High NLR and large tumor size were associated with a greater risk of 1-year mortality among patients with favorable tumor marker profile.

The aim of the current study is to assess rates of textbook outcome (TO) among Medicare beneficiaries undergoing hepatopancreatic (HP) surgery for cancer at dedicated cancer centers (DCCs) and National Cancer Institute affiliated cancer centers (NCI-CCs) versus non-DCC non-NCI hospitals. Medicare Inpatient Standard Analytic Files were utilized to identify patients undergoing HP surgery between 2013 and 2017. TO was defined as no postoperative surgical complications, no 90-day mortality, no prolonged length of hospital stay, and no 90-day readmission after discharge. Among 21,234 Medicare patients, 8.2% patients underwent surgery at DCCs whereas 32.1% underwent surgery at NCI-CCs and 59.7% underwent an operation at neither DCCs nor NCI-CCs. Although DCCs more often cared for patients with severe comorbidities [Charlson score > 5: DCCs, 1195 (68.9%), NCI-CCs, 3687 (54.1%), others, 3970 (31.3%); p

Background: The objective of this study was to examine whether the systemic immune inflammation index (SII) was associated with prognosis among patients following resection of intrahepatic cholangiocarcinoma (ICC). Methods: The impact of SII on overall (OS) and cancer-specific survival (CSS) following resection of ICC was assessed. The performance of the final multivariable models that incorporated inflammatory markers (i.e. neutrophil-to-lymphocyte ratio [NLR], platelet-to-lymphocyte ratio [PLR] and SII [platelets∗NLR]) was assessed using the Harrell's concordance index. Results: Patients with high SII had worse 5-year OS (37.7% vs 46.6%, p < 0.001) and CSS (46.1% vs 50.1%, p < 0.001) compared with patients with low SII. An elevated SII (HR = 1.70, 95% CI 1.23–2.34) and NLR (HR = 1.58, 95% CI 1.10–2.27) independently predicted worse OS, whereas high PLR (HR = 1.17, 95% CI 0.85–1.60) was no longer associated with prognosis. Only SII remained an independent predictor of CSS (HR = 1.55, 95% CI 1.09–2.21). The SII multivariable model outperformed models that incorporated PLR and NLR relative to OS (c-index; 0.696 vs 0.689 vs 0.692) and CSS (c-index; 0.697 vs 0.689 vs 0.690). Conclusion: SII independently predicted OS and CSS among patients with resectable ICC. SII may be a better predictor of outcomes compared with other markers of inflammatory response among patients with resectable ICC.

The relationship of volume and travel distance to patient outcomes after resection of gallbladder cancer (GBC) remains poorly defined.The 2004-2015 National Cancer Database was used to identify GBC resection patients and examine the impact of travel distance, hospital volume and both on overall survival (OS) and quality of care indicators.Among 10,174 patients undergoing surgery for GBC, the majority of patients were Caucasian (N = 8,175, 80%) and had a Charlson-Deyo comorbidity score of 0 (N = 6,785, 67%). On unadjusted survival analysis increasing travel distance and hospital volume were associated with improved OS (both p0.001). After controlling for competing risk factors, the 4th quartile of hospital volume was associated with a decreased hazard of death (HR 0.831, 95% CI 0.751-0.920, p0.001). When both hospital volume and travel distance were included, the association with improved OS persisted only for hospital volume (4th quartile HR 0.835, 95% CI 0.753-0.925, p0.001), whereas there was no independent association of increasing travel distance with OS.Both increasing travel distance and hospital volume were associated with improved OS; however, adjusted models demonstrated that the impact of travel distance was mediated through hospital volume.

Safety-net hospitals are critical to the US health system as they provide care to vulnerable patients. The effect of hospital safety-net burden on patient outcomes in hepatopancreaticobiliary (HPB) surgery was examined. Discharge data between 2004 and 2014 from the National Inpatient Sample were utilized. Hospitals with a safety-net burden were divided into tertiles: low (LBH) ( 33.3%). The association of hospital safety-net burden with complications, in-hospital mortality, never events, and costs were defined. Nearly 5% of the analytic cohort (n = 65,032) had surgery at a HBH. Patients treated at HBH were younger (median age, HBH 55 years vs LBH 62 years; p

We sought to assess the effect of nurse-to-patient ratio on outcomes with a focus on defining whether nurse-to-patient ratio altered outcomes relative to pancreaticoduodenectomy (PD) surgeon specific volume. Medicare SAFs from 2013–2015 were used to identify patients who underwent PD. Nurse-to-patient ratio, PD specific surgeon volume were stratified. Association of factors associated with short term outcomes was evaluated. Overall, 6668 patients (median age 73, IQR 68–77; 52.8% male) were identified. The median annual PD volume of surgeons in the highest volume tier was 24 (IQR 21–29), whereas surgeons in the lowest tier performed 2 PDs annually (IQR 1–3) (p < 0.001). Compared with hospitals that had the highest nurse-to-patient ratio tier, patients at hospitals with the lowest nurse-to-patient ratio tier were 26% more likely to have a complication (OR 1.26, 95% CI 1.02–1.55). Additionally, patients of surgeons in the lowest tier had 43% greater odds of suffering a complication compared to patients of surgeons in the highest tier (OR 1.43, 95% CI 1.11–1.84). However, patients who underwent a PD by a surgeon within the lowest tier had similar odds of a complication irrespective of nurse-to-patient ratio (OR 1.34, 95% CI 0.97–1.86). Compared with patients who underwent an operation by a surgeon in highest PD volume tier, patients treated by surgeons in the lowest tier had higher odds of post-operative complications which was not mitigated by a higher nurse-to-patient ratio.

The impact of preoperative cholangitis (PC) on perioperative outcomes among patients undergoing liver resection remains poorly defined. We sought to characterize the prevalence of PC among patients undergoing hepatectomy and define the impact of PC on postoperative outcomes. Patients who underwent liver resection between 2013 and 2015 were identified using the Center for Medicare Services (CMS) 100% Limited Data Set (LDS) Standard Analytic Files (SAFs). Short-term outcomes after liver resection, stratified by the presence of PC, were examined. Subgroup analyses were performed to evaluate the relationship between the timing of liver resection relative to PC. Among 7392 patients undergoing liver resection, 251 patients (3.4%) experienced PC. Patients with PC were more likely to be male (59.0% vs. 50.6%) and to have a benign diagnosis (34.3% vs. 19.8%) compared with patients without PC (both p

Background: There is an ongoing debate about expanding the resection criteria for hepatocellular carcinoma (HCC) beyond the Barcelona Clinic Liver Cancer (BCLC) guidelines. We sought to determine the factors that held the most prognostic weight in the pre- and postoperative setting for each BCLC stage by applying a machine learning method. Methods: Patients who underwent resection for BCLC-0, A and B HCC between 2000 and 2017 were identified from an international multi-institutional database. A Classification and Regression Tree (CART) model was used to generate homogeneous groups of patients relative to overall survival (OS) based on pre- and postoperative factors. Results: Among 976 patients, 63 (6.5%) had BCLC-0, 745 (76.3%) had BCLC-A, and 168 (17.2%) had BCLC-B HCC. Five-year OS among BCLC-0/A and BCLC-B patients was 64.2% versus 50.2%, respectively (p = 0.011). The preoperative CART model selected α-fetoprotein (AFP) and Charlson comorbidity score (CCS) as the first and second most important preoperative factors of OS among BCLC-0/A patients, whereas radiologic tumor burden score (TBS) was the best predictor of OS among BCLC-B patients. The postoperative CART model revealed lymphovascular invasion as the best postoperative predictor of OS among BCLC-0/A patients, whereas TBS remained the best predictor of long-term outcomes among BCLC-B patients in the postoperative setting. On multivariable analysis, pathologic TBS independently predicted worse OS among BCLC-0/A (hazard ratio [HR] 1.04, 95% confidence interval [CI] 1.02-1.07) and BCLC-B patients (HR 1.13, 95% CI 1.06-1.19) undergoing resection. Conclusion: Prognostic stratification of patients undergoing resection for HCC within and beyond the BCLC resection criteria should include assessment of AFP and comorbidities for BCLC-0/A patients, as well as tumor burden for BCLC-B patients. info:eu-repo/semantics/publishedVersion

BACKGROUND: In parallel to women entering general surgery training, acute care surgery (ACS) has been developing as a team-based approach to emergency general surgery (EGS). We sought to examine predictors of women surgeons in EGS generally, and ACS particularly. METHODS: From our national survey, we determined the proportion of women surgeons within EGS hospitals. We compared the proportion of women surgeons based on hospitals characteristics using chi squared tests, then regression models to measure odds of ACS relative to proportion of women. RESULTS: 779 (50.4%) hospitals had zero women surgeons. These hospitals were more likely non-ACS and non-teaching with

Formal gastrectomy is occasionally required to achieve complete cytoreduction for patients with peritoneal surface malignancies. In addition, the role of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for patients with gastric cancer is increasingly being explored. Nevertheless, data on the safety of gastrectomy at the time of CRS-HIPEC are limited.The American College of Surgeons-National Surgical Quality Improvement Program databases from 2005 to 2016 were used to identify patients who underwent CRS-HIPEC. Demographic, clinical, and perioperative outcomes were compared between patients who underwent CRS-HIPEC with and without gastrectomy.Among 1168 patients who underwent CRS-HIPEC, 43 (4%) underwent partial (n = 20) or total (n = 23) gastrectomy. Patients who underwent gastrectomy at the time of CRS-HIPEC had a longer operative time (529.3 versus 457.6 min, P = 0.004), were more likely to need an intraoperative transfusion (32.6% versus 14.3%, P = 0.001), experienced a longer length of stay (19.0 versus 11.3 d, P 0.001), and had a significantly greater complication rate (60.5% versus 27.9%, P 0.001), whereas postoperative mortality was not statistically significantly different (4.7% versus 1.4%, P = 0.09). On multivariate logistic regression, gastrectomy (odds ratio [OR] 3.52, P 0.001) was the strongest predictor of postoperative morbidity, in addition to American Society of Anesthesiologists class 4 (OR 2.82, P = 0.001), malnutrition (OR 1.63, P = 0.01), liver resection (OR 1.88, P = 0.01), and colectomy (OR 2.04, P 0.001).Patients undergoing gastrectomy at the time of CRS-HIPEC experience a substantial postoperative complication rate (60%) and extended length of stay (mean 19 d). These findings highlight the need for cautious patient selection and preoperative counseling before performing concomitant gastrectomy and CRS-HIPEC.

Given the need to increase female representation in hepatopancreatobiliary (HPB) surgery, as well as the need to increase the academic pipeline of women in this subspecialty, we sought to characterize the prevalence of female authorship in the HPB literature. In particular, the objective of the current study was to determine the proportion of women who published HPB research articles as first, second, or last author over the last decade. All articles pertaining to hepatopancreaticobiliary (HPB) surgery appearing in seven surgical journals (Annals of Surgery, British Journal of Surgery, JAMA Surgery, Annals of Surgical Oncology, HPB (Oxford), Surgery, and Journal of Gastrointestinal Surgery) were reviewed for the years 2008 and 2018. Information on sex of author, country of author’s institution, and article type was collected and entered into a computerized database. Among the 1473 index articles included in the final analytic cohort, 414 (28%) publications had a woman as the first or last author, while the vast majority (n = 1,059, 72%) had a man as the first or last author. The number of female first authors increased from 15.6% (n = 92/591) in 2008 to 25.7% (n = 227/882) in 2018 (p

Surgical resection is the only potentially curative treatment for patients with colorectal, liver, and pancreatic cancers. Although these procedures are performed with low mortality, rates of complications remain relatively high following hepatopancreatic and colorectal surgery. The American College of Surgeons (ACS) National Surgical Quality Improvement Program was utilized to identify patients undergoing liver, pancreatic and colorectal surgery from 2014 to 2016. Decision tree models were utilized to predict the occurrence of any complication, as well as specific complications. To assess the variability of the performance of the classification trees, bootstrapping was performed on 50% of the sample. Algorithms were derived from a total of 15,657 patients who met inclusion criteria. The algorithm had a good predictive ability for the occurrence of any complication, with a C-statistic of 0.74, outperforming the ASA (C-statistic 0.58) and ACS-Surgical Risk Calculator (C-statistic 0.71). The algorithm was able to predict with high accuracy thirteen out of the seventeen complications analyzed. The best performance was in the prediction of stroke (C-statistic 0.98), followed by wound dehiscence, cardiac arrest, and progressive renal failure (all C-statistic 0.96). The algorithm had a good predictive ability for superficial SSI (C-statistic 0.76), organ space SSI (C-statistic 0.76), sepsis (C-statistic 0.79), and bleeding requiring transfusion (C-statistic 0.79). Machine learning was used to develop an algorithm that accurately predicted patient risk of developing complications following liver, pancreatic, or colorectal surgery. The algorithm had very good predictive ability to predict specific complications and demonstrated superiority over other established methods.

Background We sought to characterize epidural analgesia (EA) use among Medicare patients undergoing hepatopancreatic (HP) procedures, identify factors associated with EA use and asses perioperative outcomes. Methods Patients undergoing HP surgery were identified using the Inpatient Standard Analytic Files. Logistic regression was utilized to identify factors associated with EA receipt, and assess associations of EA with in-hospital outcomes and Medicare expenditures. Results Among 20,562 patients included in the study, 6.7% (n =1362) had EA. There was no difference in the odds of complications (OR 1.05, 95% CI 0.93–1.19) or blood transfusions (OR 0.90, 95% CI 0.79–1.03) with EA versus conventional analgesia (CA). The odds of prolonged LOS (OR 1.16, 95% CI 1.03–1.30) were higher with EA; the odds of in-hospital mortality were higher with conventional analgesia (OR 1.90, 95% CI 1.28–2.83). Medicare payments for liver surgery were comparable among EA ($19,500) versus conventional analgesia ($19,300, p = 0.85) and slightly higher for EA ($23,600) versus conventional analgesia ($22,000, p Conclusion EA utilization among Medicare patients undergoing HP was low. While EA was not associated with morbidity, it resulted in an average additional one day LOS and slightly higher expenditures in pancreatic surgery.

BACKGROUND Few data are available regarding the management and outcomes among patients with sarcomatoid hepatocellular carcinoma (HCC) due to its rarity. METHODS Patients diagnosed with sarcomatoid HCC from 2004 through 2015 were identified in the National Cancer Data Base. Overall survival (OS) was calculated among patients with sarcomatoid versus conventional HCC using a 1:3 propensity score matching based on sex, age, and American Joint Committee on Cancer (AJCC) stage of disease. RESULTS The final analytic cohort included 104 patients with sarcomatoid HCC and 312 patients with conventional HCC. Patients with sarcomatoid HCC more often had a larger median tumor size (8.5 cm vs 5.4 cm; P

While patient- and hospital-level factors affecting outcomes of patients undergoing pancreatoduodenectomy (PD) have been well described separately, the relative impact of these factors on in-hospital mortality has not been comprehensively assessed. Retrospective review of the National Inpatient Sample database (January 2004–December 2014) was conducted to identify patients undergoing PD. Factors associated with in-hospital mortality after PD were analyzed after adjusting for previously defined patient- and hospital-level risk factors. A total of 9639 patients who underwent a PD at 2325 hospitals were identified. Median patient age was 57 years (IQR 66–73). Overall, mortality following PD was 3.2%. When patient- and hospital-level characteristics were analyzed in the same model, patient-level characteristic associated with increased odds of in-hospital mortality included increasing patient age (OR 1.05, 95% CI 1.03–1.06/per 5 years increase), male sex (OR 1.47, 95% CI 1.16–1.86), the presence of liver disease (OR 3.03, 95% CI 1.99–4.61), chronic kidney disease (OR 1.78, 95% CI 1.18–2.68), and congestive heart failure (OR 2.48, 95% CI 1.65–3.74). The only hospital characteristic associated with odds of mortality following PD included compliance with Leapfrog volume standards (OR 0.70, 95% CI 0.54–0.92). Patient-level factors, such as advanced comorbidities, male sex, and increased age, contributed the most to increased risk of mortality after PD. Hospital volume was the only hospital-level factor contributing to risk of in-hospital mortality following PD.

Scirrhous hepatocellular carcinoma (HCC) is a rare primary liver tumor characterized by extensive fibrosis and production of parathyroid hormone–related peptide. There have been conflicting reports on patient survival in scirrhous versus non-scirrhous HCC. The objective of the present study was to define the clinical features, practice patterns, and long-term outcomes of patients with scirrhous HCC versus non-scirrhous HCC in a propensity score–matched cohort. A propensity score–matched cohort was created using data from the National Cancer Database for 2004 to 2015. A multivariable Cox proportional hazards regression analysis was performed to assess the effect of the scirrhous HCC variant on overall survival. Among the 70,426 patients with a diagnosis of HCC who met the inclusion criteria, 99.8% had non-scirrhous HCC (n = 70,290) whereas a small subset had scirrhous HCC (n = 136, 0.19%). While 20,330 (28.9%) patients underwent liver-directed therapy (resection, ablation, and transplantation), the majority did not (n = 50,096, 71.1%). After propensity matching, there were no difference in 1-, 3-, or 5-year overall survival among patients with scirrhous versus non-scirrhous HCC (1-year overall survival (OS), 53.7% versus 51.0%; 3-year OS, 34.6% versus 28.7%; and 5-year OS, 18.0% versus 21.0%, respectively; p = 0.52). While the scirrhous HCC variant was not associated with survival (hazard ratio [HR] 0.93, 95% CI 0.74–1.16), non-receipt of liver-directed therapy (HR 0.24, 95% CI 0.18–0.32), advanced AJCC stage (III/IV) (HR 2.14, 95% CI 1.55–2.95), and non-academic facilities (HR 0.60, 95% CI 0.49–0.73) remained associated with worse survival. Patients with the scirrhous variant had a comparable overall survival compared with individuals who had non-scirrhous HCC. Failure to receive liver-directed therapy, advanced AJCC stage (III/IV), and treatment at a non-academic facility was strongly associated with a worse long-term prognosis.
