Background There has been increased interest in understanding how social determinants of health (SDH) may affect care both in the medical and surgical setting. We sought to define the impact of various aspects of social vulnerability on the ability of patients to achieve a “textbook outcome” (TO) following hepatopancreatic surgery. Methods Medicare beneficiaries who underwent hepatopancreatic resection between 2013 and 2017 were identified using the Medicare database. Social vulnerability was defined using the Centers for Disease Control Social Vulnerability Index (SVI), which is comprised of four subthemes: socioeconomic (SE), household composition and disability (HCD), minority status and language (MSL), and housing type and transportation (HTT). TO was defined as the composite endpoint: absence of 90-day mortality or readmission, absence of an extended length of stay (LOS), and no complications during the index admission. Cluster analysis was used to identify vulnerability cohorts, and multivariable logistic regression was utilized to assess the impact of these SVI subthemes on the likelihood to achieve a textbook outcome. Results Among 37,707 Medicare beneficiaries, 64.9% (n = 24,462) of patients underwent pancreatic resection while 35.1% (n = 13,245) underwent hepatic resection. Median patient age was 72 years (IQR: 68–77), just over one-half were male (51.9%; n = 19,558), and the median CCI was 3 (IQR: 2–8). Cluster analysis revealed five distinct SVI profiles with wide variability in the distribution of SVI subthemes, ranging from 15 (profile 1 IQR: 7–26) to 83 (profile 5 IQR: 66–93). The five profiles were grouped into 3 categories based on median composite SVI: “low vulnerability” (profile 1), “average vulnerability” (profiles 2 and 3), or “high vulnerability” (profiles 4 and 5). The rate of TO ranged from 44.6% in profile 5 (n = 4022) to 49.2% in profile 1 (n = 4836). Multivariable analyses comparing patients categorized into the two average SVI profiles revealed that despite having similar composite SVI scores, the risk of adverse postoperative outcomes was not similar. Specifically, patients from profile 5 had lower odds of achieving a TO (OR 0.89, 95%CI: 0.83–0.95) and higher odds of 90-day mortality (OR 1.29, 95%CI: 1.15–1.44) versus patients in profile 4. Conclusion Distinct profiles of SVI subtheme characteristics were independently associated with postoperative outcomes among Medicare beneficiaries undergoing HP surgery, even among patients with similar overall composite SVI scores.

The effect of varying severity and timing of complications after hepatic resection on 30-day mortality has not been thoroughly examined. National Surgical Quality Improvement Program Patient User Files (NSQIP-PUF) were used to identify patients who underwent elective hepatic resection between 2014 and 2019. The impact of number, timing, and severity of complications on 30-day mortality was examined. Among 25,084 patients who underwent hepatic resection, 7436 (29.9%) patients developed at least one NSQIP complication, while 2688 (10.7%) had multiple (≥2) complications. Overall, 30-day mortality was 1.7% (n=424), among whom 81.4% (n=345) patients had ≥2 complications. The 30-day mortality was highest among patients with three consecutive severe complications (47.8%), as well as patients with one non-severe and two subsequent severe complications (47.6%). The adjusted probability of 30-day mortality was 35.5% (95%CI: 29.5–41.4%) when multiple severe complications occurred within the first postoperative week and 16.2% (95%CI: 7.2–25.1%) when the second severe complication occurred at least one week apart. The adjusted risk of 30-day mortality after even two non-severe complications was as high as 5.3% (95%CI: 3.7–6.9%) when the second complication occurred within a week postoperatively. Approximately 1 in 10 patients developed multiple complications following hepatectomy. Timing and severity of complications were independently associated with 30-day mortality.

Care delivered in hospital-based emergency departments (ED) is a target for cost savings. ED utilization following hepatopancreatic surgery remains poorly defined. We sought to define the rate of ED utilization following liver and pancreatic resection, as well as to identify factors associated with ED visits post-discharge. The Medicare 100% Standard Analytic Files were used to identify Medicare beneficiaries who underwent hepatectomy or pancreatectomy between 2013 and 2017. Claims associated with ED services were identified using the relevant Revenue Center Codes. Patient characteristics and postoperative outcomes associated with ED care within 30 days of discharge were investigated. Among 37,707 patients who underwent hepatopancreatic surgery, 10,323 (27.4%) had at least one ED visit within 30 days of discharge. Patients presenting to the ED were more likely to be male (OR 1.13, 95%CI 1.07–1.18). Patients undergoing a pancreatectomy (OR 1.39, 95%CI 1.32–1.47), as well as patients who had a perioperative complication (OR 1.16, 95%CI 1.10–1.23) and patients not discharged home (OR 1.41, 95%CI 1.33–1.49), were more likely to require ED care. In contrast, patients undergoing resection for cancer or surgery for an elective basis were less likely to present to the ED postoperatively (OR 0.92, 95%CI 0.87–0.97 and OR 0.22, 95%CI 0.20–0.23, respectively). Patients often had multiple ED visits within 30 days of discharge as 37.2% of patients presented to the ED with at least 2 visits. Visits were also most common in the immediate postoperative period, with 30.9% of ED visits taking place in the first 2 days from discharge. Among patients requiring postoperative ED care, 53.9% were readmitted within 30 days. More than 1 in 4 patients undergoing hepatopancreatic surgery presented to the ED within 30 days of discharge, with most patients returning to the ED within the first week of discharge. A subset of patients had multiple ED visits. Future efforts should target patients most likely to be high ED utilizers to avoid the need for early post-discharge ED use.

Racial/ethnic disparities in cancer outcomes may relate to variations in receipt of National Comprehensive Cancer Network (NCCN) guideline compliant care. Patients undergoing resection of cholangiocarcinoma (CCA) between 2004 and 2015 were identified using the National Cancer Database (NCDB). Institutions treating Black and Hispanic patients within the top decile were categorized as minority-serving hospitals (MSH). Factors associated with receipt of NCCN-compliant care, and the impact of NCCN compliance on overall survival (OS), were evaluated. Among 16,108 patients who underwent resection of CCA, the majority of patients were treated at non-MSH (n = 14,779, 91.8%), while a smaller subset underwent resection of CCA at MSH (n = 1329, 8.2%). Patients treated at MSH facilities tended to be younger (MSH: 65 years versus non-MSH: 67 years), Black or Hispanic (MSH: 59.9% versus non-MSH: 13.4%), and uninsured (MSH: 11.6% versus non-MSH: 2.2%). While overall compliance with NCCN care was 73.0% (n = 11,762), guideline-compliant care was less common at MSH (MSH: 68.8% versus non-MSH: 73.4%; p

We sought to construct and validate a model of cancer surgeon approaches to patient-centered decision-making (PCDM) and compare applications of that model relative to surgical specialties. Ten PCDM strategies were assessed using a cross-sectional survey administered online to 295 board-certified cancer surgeons. Structural equation modeling was used to empirically validate and compare approaches to PCDM. Within the full sample, 7 strategies comprised a latent construct labeled, “physical & emotional accessibility,” associated with surgeon approaches to PCDM (β = 0.37, p

Introduction: Although preoperative α-fetoprotein (AFP) has been recognized as an important tumor marker among patients with hepatocellular carcinoma (HCC), the predictive value of AFP levels at the time of recurrence (rAFP) on post-recurrence outcomes has not been well examined. Methods: Patients undergoing curative-intent resection of HCC between 2000 and 2017 were identified using a multi-institutional database. The impact of rAFP on post-recurrence survival, as well as the impact of rAFP relative to the timing and treatment of HCCrecurrence wereexamined. Results: Among 852 patients who underwent resection of HCC, 307 (36.0%) individuals developed a recurrence. The median rAFP level was 8ng/mL (interquartile range 3–100). Among the 307 patients who developed recurrence, 3-year post-recurrence survival was 48.5%. Patients with rAFP > 10ng/mL had worse 3-year post-recurrence survival compared with individuals with rAFP < 10ng/mL (28.7% vs. 65.5%, p < 0.001). rAFP correlated with survival among patients who had early (3-year survival; rAFP > 10 vs. < 10ng/mL: 30.1% vs. 60.2%, p < 0.001) or late (18.0% vs. 78.7%, p = 0.03) recurrence. Furthermore, rAFP levels predicted 3-year post-recurrence survival among patients independent of the therapeutic modality used to treat the recurrent HCC (rAFP > 10 vs. < 10ng/mL; ablation: 41.1% vs. 76.0%; intra-arterial therapy: 12.9% vs. 46.1%; resection: 37.5% vs. 100%; salvage transplantation: 60% vs. 100%; all p < 0.05). After adjusting for competing risk factors, patients with rAFP > 10ng/mL had a twofold higher hazard of death in the post-recurrence setting (hazard ratio 1.96, 95% confidence interval 1.26–3.04). Conclusion: AFP levels at the time of recurrence following resection of HCC predicted post-recurrence survival independent of the secondary treatment modality used. Evaluating AFP levels at the time of recurrence can help inform post-recurrence risk stratification of patients with recurrent HCC.

While social determinants of health may adversely affect various populations, the impact of residential segregation on surgical outcomes remains poorly defined. The objective of the current study was to examine the association between residential segregation and the likelihood to achieve a textbook outcome (TO) following cancer surgery. The Medicare 100% Standard Analytic Files were reviewed to identify Medicare beneficiaries who underwent resection of lung, esophageal, colon, or rectal cancer between 2013 and 2017. Shannon’s integration index, a measure of residential segregation, was calculated at the county level and its impact on composite TO [no complications, no prolonged length of stay (LOS), no 90-day readmission, and no 90-day mortality] was examined. Among 200,509 patients who underwent cancer resection, the overall incidence of TO was 56.0%. The unadjusted likelihood of achieving a TO was lower among patients in low integration areas [low integration: n = 19,978 (55.0%) vs. high integration: n = 18,953 (59.3%); p

Inter-hospital transfer (IHT) may help reduce failure-to-rescue (FTR) by transferring patients to centers with a higher level of expertise than the index hospital. We sought to identify factors associated with an IHT and examine if IHT was associated with improved outcomes after complex gastrointestinal cancer surgery. Medicare Inpatient Standard Analytic Files were utilized to identify patients with >1 postoperative complication following resection for esophageal, pancreatic, liver, or colorectal cancer between 2013 and 2017. Multivariable logistic regression was used to examine the association of different factors with the chance of IHT, as well as the impact of IHT on failure-to-rescue (FTR) and expenditures. Among 39,973 patients with >1 postoperative complications, 3090 (7.7%) patients were transferred to a secondary hospital. The median LOS at the index hospital prior to IHT was 10 days (IQR, 6–17 days). Patients who underwent IHT more often had experienced multiple complications at the index hospital compared with non-IHT patients (57.7% vs. 38.9%) (p

Patients can experience barriers and disparities to access high-quality cancer care. This study sought to characterize receipt of surgery and chemotherapy among Medicare beneficiaries with a diagnosis of early-stage pancreatic adenocarcinoma cancer (PDAC) relative to race/ethnicity and social vulnerability. The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was used to identify patients with a diagnosis of early-stage (stage 1 or 2) PDAC between 2004 and 2016. Data were merged with the CDC’s Social Vulnerability Index (SVI) at the beneficiary’s county of residence. Multivariable, mixed-effects logistic regression was used to assess the association of SVI with resection. Among 15,931 older Medicare beneficiaries with early-stage PDAC (median age, 77 years; interquartile range [IQR], 71–82 years), the majority was White (n = 12,737, 80.0 %), whereas a smaller subset was Black or Latino (n = 3194, 20.0 %) A minority of patients was more likely to live in highly vulnerable communities (low SVI: white [90.5 %] vs minority [9.5 %] vs high SVI: white [71.9 %] vs minority [28.1 %]; p < 0.001). Use of resection for early-stage PDAC was lowest among the patients who resided in high-SVI areas (low [38.0 %] vs average [34.3 %] vs high [31.9 %]; p < 0.001). The minority patients were less likely to undergo resection than the White patients (no resection: white [64.1 %] vs minority [70.7 %]; p < 0.001). The median SVI was higher among the patients who underwent resection (57.6; IQR, 36.0–81.0) than among those who did not (60.4; IQR, 41.9–84.3), and increased SVI resulted in a decline in the likelihood of resection (SVI trend: OR, 0.98; 95 % confidence interval [CI], 0.97–1.00), especially among the minority patients. Minority patients from high-SVI counties had markedly lower odds of preoperative chemotherapy than minority patients from a low-SVI neighborhood (OR, 0.62; 95 % CI, 0.52–0.73). Older Medicare beneficiaries with early-stage PDAC residing in counties with higher social vulnerability had lower odds of undergoing pancreatic resection, which was more pronounced among minority versus older White Medicare beneficiaries.

Post-acute care (PAC) services can include home healthcare, long-term care hospitals, and skilled nursing facilities. We sought to define factors associated with PAC discharge disposition among Medicare beneficiaries who underwent hepatectomy for hepatocellular carcinoma (HCC). Data for Medicare beneficiaries with a diagnosis of HCC and who underwent a hepatectomy between 2004 and 2015 were retrieved from the SEER-Medicare database. Discharge disposition was defined as routine (HSC: discharged to home) or non-routine (SNF/ICF, discharged to skilled nursing/intermediate care facilities, or HHA, discharge to home with home health agency). The Cochran-Mantel-Haenszel test and multivariable logistic regression were used to assess trends in discharge disposition. Among 1305 patients, the median patient age at diagnosis was 72 years (IQR: 68–76). Approximately 4 in 5 patients were discharged to HSC (77.4%; n = 1010). The odds of a non-routine discharge decreased by 7.0% annually from 2004 to 2015 (ORtrend, 0.93; 95%CI, 0.89–0.97; ptrend = 0.001). Several factors were associated with non-routine discharge, including patient age (OR 1.06, 95%CI 1.04–1.09) and longer LOS (OR 1.07, 95%CI 1.05–1.10). In contrast, patients who had a minor hepatectomy (OR 0.69, 95%CI 0.52–0.93) at a teaching hospital (OR 0.63, 95%CI 0.45–0.89) had lower odds of a non-routine discharge (all P < 0.05). HSC discharge increased over time (2004–2007 (n = 205, 68.1%) vs. 2008–2011 (n = 330, 77.8%) vs. 2012–2015 (n = 475, 81.9%); ptrend < 0.001). Over the same time period, there was a decreasing trend in 90-day readmission (2004–2007 (n = 91, 30.2%) vs. 2008–2011 (n = 107, 25.2%) vs. 2012–2015 (n = 129, 22.2%); ptrend = 0.03). Utilization of PAC services following hepatic resection of HCC decreased by 57.0% between 2004 and 2015. These data highlight that decreased PAC utilization was not generally associated with higher readmission rates following resection of HCC.

The impact of depression on utilization of post-discharge care and overall episode of care expenditures remains poorly defined. We sought to define the impact of depression on postoperative outcomes, including discharge disposition, as well as overall expenditures associated with the global episode of surgical care. The Medicare 100% Standard Analytic Files were used to identify patients undergoing resection for esophageal, colon, rectal, pancreatic, and liver cancer between 2013 and 2017. The impact of depression on inpatient outcomes, as well as home health care and skilled nursing facilities utilization and expenditures, was analyzed. Among 113,263 patients, 14,618 (12.9%) individuals had depression. Patients with depression were more likely to experience postoperative complications (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.31–1.42), extended length of stay (LOS) (OR 1.41, 95% CI 1.36–1.47), readmission within 90 days (OR 1.20, 95% CI 1.14–1.25), as well as 90-day mortality (OR 1.35, 95% CI 1.27–1.42) (all p < 0.05). In turn, the proportion of patients who achieved a textbook outcome following cancer surgery was lower among patients with depression (no depression: 53.3% vs. depression: 45.3%; OR 0.70, 95% CI 0.68–0.73). Patients with a preexisting diagnosis of depression had higher odds of additional post-discharge expenditures compared with individuals without a diagnosis of depression (OR 1.42; 95% CI 1.35–1.50); patients with a preexisting diagnosis of depression ($10,500, IQR $3,200–$22,500) had higher median post-discharge expenditures versus patients without depression ($6600, IQR $2100–$17,400) (p < 0.001). On multivariable analysis, after controlling for other factors, depression remained associated with a 19.0% (95% confidence interval [CI] 15.7–22.3%) increase in post-discharge expenditures. Patients with depression undergoing resection for cancer had worse in-patient outcomes and were less likely to achieve a TO. Patients with depression were more likely to require post-discharge care and had higher post-discharge expenditures.

The increasing incidence of hepatocellular carcinoma (HCC) coupled with rising health care costs contributes to high end-of-life expenditures. The current study aimed to characterize health care expenditures and hospice use among patients with HCC using a large, national database. The Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database was used to identify patients with HCC. Logistic regression was used to identify factors associated with overall hospice use and end-of-life expenditures among individuals who died of HCC. Among 14,369 Medicare beneficiaries with HCC, 8069 (63.7 %) used hospice. Racial/ethnic minority patients were less likely to use hospice services during the last year of life than white patients (no hospice: n = 2034 [44.3 %] vs. hospice: n = 2513 [31.1 %]). Social vulnerability also had an impact on the likelihood of patients using hospice services; in particular, the probability of hospice use among patients declined as social vulnerability increased (P < 0.05). Hospice use was associated with an approximate $10,000 decrease in inpatient expenditures (hospice: US$7900 [IQR, US$0–26,600] vs. no hospice: US$18,000 [IQR $400-49,100]; P < 0.001) and $1300 decrease in outpatient expenditures (hospice: US$900 [IQR, US$0–4500] vs. non-hospice: US$2200 [IQR, US$200–7900; P < 0.001) compared with individuals who did not use hospice. Minority patients and individuals residing in high-vulnerability areas were less likely to use hospice. Patients who used hospice at the end of life had a reduction in inpatient and outpatient Medicare claims. Patients with HCC in need of hospice services should be ensured timely referral regardless of race/ethnicity or social vulnerability.

The provision of spiritual care by an interprofessional healthcare team is an important, yet frequently neglected, component of patient-centered cancer care. The current study aimed to assess the relationship between individual and occupational factors of healthcare providers and their self-reported observations and behaviors regarding spiritual care in the oncologic encounter. A cross-sectional survey was administered to healthcare providers employed at a large Comprehensive Cancer Center. Pearson’s chi-square test and logistic regression were used to determine potential associations between provider factors and their observations and behaviors regarding spiritual care. Among the participants emailed, 420 followed the survey link, with 340 (80.8%) participants completing the survey. Most participants were female (82.1%) and Caucasian (82.6%) with a median age was 35 years (IQR: 31–48). Providers included nurses (64.7%), physicians (17.9%), and “other” providers (17.4%). There was a difference in provider observations about discussing patient issues around religion and spirituality (R&S). Specifically, nurses more frequently inquired about R&S (60.3%), while physicians were less likely (41.4%) (p = 0.028). Also, nurses more frequently referred to chaplaincy/clergy (71.8%), while physicians and other providers more often consulted psychology/psychiatry (62.7%, p < 0.001). Perceived barriers to not discussing R&S topics included potentially offending patients (56.5%) and time limitations (47.7%). Removing extrinsic barriers and understanding intrinsic influences can improve the provision of spiritual care by healthcare providers.

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.

Integration of palliative care services into the surgical treatment plan is important for holistic patient care. We sought to examine the association between patient race/ethnicity and county-level vulnerability relative to patterns of hospice utilization. Medicare Standard Analytic Files were used to identify patients undergoing lung, esophageal, pancreatic, colon, or rectal cancer surgery between 2013 and 2017. Data were merged with the Centers for Disease Control and Prevention’s social vulnerability index (SVI). Logistic regression was utilized to identify factors associated with overall hospice utilization among deceased individuals. A total of 54,256 Medicare beneficiaries underwent lung (n = 16,645, 30.7%), esophageal (n = 1427, 2.6%), pancreatic (n = 6183, 11.4%), colon (n = 26,827, 49.4%), or rectal (n = 3174, 5.9%) cancer resection. Median patient age was 76 years (IQR 71–82 years), and 28,887 patients (53.2%) were male; the majority of individuals were White (91.1%, n = 49,443), while a smaller subset was Black or Latino (racial/ethnic minority: n = 4813, 8.9%). Overall, 35,416 (65.3%) patients utilized hospice services prior to death. Median SVI was 52.8 [interquartile range (IQR) 30.3–71.2]. White patients were more likely to utilize hospice care compared with minority patients (OR 1.24, 95% CI 1.17–1.31, p

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.

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.

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.

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: 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.

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

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.

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.

INTRODUCTION: Disparities in health and healthcare access remain a major problem in the United States. The current study sought to investigate the relationship between patient insurance status and hospital selection for surgical care. METHODS: Patients who underwent liver or pancreatic resection for cancer between 2004 and 2014 were identified in the National Inpatient Sample. The association of insurance status and hospital type was examined. RESULTS: In total, 22,254 patients were included in the study. Compared with patients with private insurance, Medicaid patients were less likely to undergo surgery at urban non-teaching hospitals (OR=0.36, 95%CI 0.22–0.59) and urban teaching hospitals (OR=0.54, 95%CI 0.34–0.84) than rural hospitals. Medicaid patients were less likely to undergo surgery at private investor-owned hospitals (OR=0.53, 95%CI 0.38– 0.73) than private non-profit hospitals. In contrast, uninsured patients were 2.2-fold more likely to go to government funded hospitals rather than private non-profit hospitals (OR=2.19, 95%CI 1.76–2.71). CONCLUSION: Insurance status was strongly associated with the type of hospital in which patients underwent surgery for liver and pancreatic cancers. Addressing the reasons for inequitable access to different hospital settings relative to insurance status is essential to ensure that all patients undergoing pancreatic or liver surgery receive high quality surgical care.

Intrahepatic cholangiocarcinoma (ICC) remains an uncommon disease with a rising incidence worldwide. We sought to identify trends in therapeutic approaches and differences in patient outcomes based on facility types. Between January 1, 2004, and December 31, 2015, a total of 27,120 patients with histologic diagnosis of ICC were identified in the National Cancer Database and were enrolled in this study. The incidence of ICC patients increased from 1194 in 2004 to 3821 in 2015 with an average annual increase of 4.16% (p
