While disadvantaged neighborhoods may be associated with worse outcomes and earlier death, the relationship between economic opportunity and surgical outcomes remains unexplored.Medicare beneficiaries who underwent AAA, CABG, colectomy or cholecystectomy were identified and stratified into quintiles based on upward economic mobility. Risk-adjusted probability of adverse postoperative outcomes were examined relative to economic mobility.Among 1,081,745 Medicare beneficiaries (age: 75.5 years, female: 43.0%, White: 91.3%), risk-adjusted 30-day postoperative mortality decreased in a stepwise fashion from 6.0%(5.9-6.1) in the lowest quintile of upward economic mobility to 5.3%(5.2-5.4) in highest upward economic mobility (lowest vs. highest economic mobilityobility OR:1.14 (95%CI:1.11-1.17)). Similar associations were noted for postoperative complications (OR:1.04, 95%CI:1.02-1.06), extended length-of-stay (OR:1.07, 95%CI:1.06-1.09), and 30-day readmission (OR:1.04, 95%CI:1.02-1.05). Black beneficiaries had a higher risk of post-operative mortality across upward economic mobility quintiles except within the highest upward mobility group (referent, White patients, OR:0.93, 95%CI:0.79-1.09, p=0.355).Economic upward mobility was associated with post-operative outcomes. Race-based differences were mitigated at the highest levels of upward economic mobility, highlighting the importance of socioeconomics as a health equity lever.

In order to investigate the optimal approach for synchronous colorectal liver metastases (sCRLM), we sought to use the "win ratio" (WR), a novel statistical approach, to assess the relative benefit of simultaneous versus staged surgical treatment.Patients who underwent hepatectomy for sCRLM between 2008 and 2020 were identified from a multi-institutional database. The WR approach was utilized to compare composite outcomes of patients undergoing simultaneous versus staged resection.Among 1116 patients, 642 (57.5%) presented with sCRLM; 290 (45.2%) underwent simultaneous resection, while 352 (54.8%) underwent staged resection. In assessing the composite outcome, staged resection yielded a WR of 1.59 (95%CI 1.47-1.71) over the simultaneous approach for sCRLM. The highest WR occurred among patients requiring major hepatectomy (WR = 1.93, 95%CI 1.77-2.10) compared with patients who required minor liver resection (WR = 1.55, 95%CI 1.44-1.70).Staged resection was superior to simultaneous resection for sCRLM based on a WR assessment.

The "win ratio" (WR) is a novel statistical technique that hierarchically weighs various postoperative outcomes (eg, mortality weighted more than complications) into a composite metric to define an overall benefit or "win." We sought to use the WR to assess the impact of social vulnerability on the likelihood of achieving a "win" after hepatopancreatic surgery.Individuals who underwent an elective hepatopancreatic procedure between 2013 and 2017 were identified using the Medicare database, which was merged with the Center for Disease Control and Prevention's Social Vulnerability Index. The win ratio was defined based on a hierarchy of postoperative outcomes: 90-day mortality, perioperative complications, 90-day readmissions, and length of stay. Patients matched based on procedure type, race, sex, age, and Charlson Comorbidity Index score were compared and assessed relative to win ratio.Among 32,557 Medicare beneficiaries who underwent hepatectomy (n = 11,621, 35.7%) or pancreatectomy (n = 20,936, 64.3%), 16,846 (51.7%) patients were male with median age of 72 years (interquartile range 68-77) and median Charlson Comorbidity Index of 3 (interquartile range 2-8), and a small subset of patients were a racial/ethnic minority (n = 3,759, 11.6%). Adverse events associated with lack of a postoperative optimal outcome included 90-day mortality (n = 2,222, 6.8%), postoperative complication (n = 8,029, 24.7%), readmission (n = 6,349, 19.5%), and length of stay (median: 7 days, interquartile range 5-11). Overall, the patients from low Social Vulnerability Index areas were more likely to "win" with a textbook outcome (win ratio 1.07, 95% confidence interval 1.01-1.12) compared with patients from high social vulnerability counties; in contrast, there was no difference in the win ratio among patients living in average versus high Social Vulnerability Index (win ratio 1.04, 95% confidence interval 0.98-1.10). In assessing surgeon volume, patients who had a liver or pancreas procedure performed by a high-volume surgeon had a higher win ratio versus patients who were treated by a low-volume surgeon (win ratio 1.21, 95% confidence interval 1.16-1.25). In contrast, there was no difference in the win ratio (win ratio 1.01, 95% confidence interval 0.97-1.06) among patients relative to teaching hospital status.Using a novel statistical approach, the win ratio ranked outcomes to create a composite measure to assess a postoperative "win." The WR demonstrated that social vulnerability was an important driver in explaining disparate postoperative outcomes.

We sought to evaluate the utility and validity of ICU-free days and ventilator-free days as candidate outcomes for OHCA trials.We conducted a secondary analysis of the Pragmatic Airway Resuscitation Trial. We determined ICU-free (days alive and out of ICU during the first 30 days) and ventilator-free days (days alive and without mechanical ventilation). We determined ICU-free and ventilator-free day distributions and correlations with Modified Rankin Scale (MRS). We tested associations with trial interventions (laryngeal tube (LT), endotracheal intubation (ETI)) using continuous (t-test), non-parametric (Wilcoxon Rank-Sum test - WRS), count (negative binomial - NB) and survival models (Cox proportional hazards (CPH) and competing risks regression (CRR)). We conducted bootstrapped simulations to estimate statistical power.ICU-free days was skewed; median 0 days (IQR 0, 0), survivors only 24 (18, 27). Ventilator-free days was skewed; median 0 (IQR 0, 0) days, survivors only 27 (IQR 23, 28). ICU-free and ventilator-free days correlated with MRS (Spearman's ρ = -0.95 and -0.97). LT was associated with higher ICU-free days using t-test (p = 0.001), WRS (p = 0.003), CPH (p = 0.02) and CRR (p = 0.04), but not NB (p = 0.13). LT was associated with higher ventilator-free days using t-test (p = 0.001), WRS (p = 0.001) and CRR (p = 0.03), but not NB (p = 0.13) or CPH (p = 0.13). Simulations suggested that t-test and WRS would have had the greatest power to detect the observed ICU- and ventilator-free days differences.ICU-free and ventilator-free days correlated with MRS and differentiated trial interventions. ICU-free and ventilator-free days may have utility in the design of OHCA trials.

Background We sought to define the impact of high- versus low-quality hospitals on the risk of adverse outcomes among patients undergoing hepatopancreatic surgery relative to social vulnerability. Social vulnerability is an important factor associated with risk of adverse postoperative outcomes. Methods Patients from 2013 to 2017 were identified from the Medicare Inpatient Standard Analytic File. Hospital quality was determined by calculating risk-adjusted probability to achieve a textbook outcome. The Social Vulnerability Index was used to categorize patients. Risk-adjusted probability of mortality, morbidity, and textbook outcome was examined across varying social vulnerability indices stratified by low-, average-, and high-quality hospitals. Results Among 27,000 patients who underwent a pancreatectomy (67%) or hepatectomy (33%%), median patient age was 72 years, 48% were female, and 89% were White; mean Social Vulnerability Index was 49. Risk-adjusted 90-day mortality (odds ratio: 1.32, 95% CI: 1.20–1.59, P = .004) and postoperative complications (odds ratio: 1.12, 95% confidence interval: 1.00–1.24, P = .044) were both higher among beneficiaries from the highest social vulnerability counties versus the lowest counties. At low-quality hospitals, patients from the highest vulnerability counties had 70% higher odds of mortality (odds ratio: 1.70, 95% confidence interval: 1.16–2.48, P = .007), 31% higher odds of overall morbidity odds ratio: 1.31, 95% confidence interval: 1.05–2.63, P = .013), and 19% lower odds of achieving a textbook outcome (odds ratio: 0.81, 95% confidence interval: 0.66–0.99, P = .035)—all of which were markedly worse compared with outcomes achieved at high-quality hospitals. Conclusion Among patients with increased social vulnerability, outcomes were considerably better at high-quality hospitals. Referral of socially vulnerable patients to high-quality hospitals represents an important opportunity to ensure optimal outcomes after complex surgery.

Introduction Social vulnerability is an important driver of disparate surgical outcomes, however the extent to which certain types of vulnerability impact outcomes is poorly understood. Methods Medicare beneficiaries 65 years or older who underwent one of four operations were identified. Multivariable mixed-effects logistic regression was used to measure the association of four social vulnerability subthemes from the social vulnerability index (SVI) were assessed relative to the likelihood to achieve a textbook outcome (TO). Results Among 579,846 Medicare beneficiaries, median age was 74 years and most patients (536,455,92.5%) were White/non-Hispanic. On multivariable analysis, the overall impact of the composite SVI metric on the odds to achieve a postoperative TO was lower among White/non-Hispanic patients (Δ25%ile SVI:OR:0.98,95%CI:0.97–0.98) compared with ethnic/minority patients (Δ25%ile SVI:OR:0.93,95%CI:0.91–0.94). Increasing vulnerability in the subthemes of socioeconomic status (Δ25%ile SVI:ethnic/minority:OR:0.92, 95%CI:0.91–0.94) and household composition (Δ25%ile SVI:ethnic/minority:OR:0.92,95%CI:0.91–0.94) was associated with a greater likelihood not to achieve a TO among minority patients. Conclusions Worsening SES and household compositions & disability had a detrimental effect on odds of TO following surgery with the most pronounced effect on non-White minority patients.

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.

BACKGROUND The association of different social vulnerability subthemes (ie, socioeconomic status, household composition and disability, minority status and language, and housing and transportation) with surgical outcomes remains poorly defined. The current study aimed to identify distinct profiles of social vulnerability among Medicare beneficiaries and define the association of these profiles with postoperative outcomes. METHODS The Medicare 100% Standard Analytic Files were used to identify patients undergoing lung resection, coronary artery bypass grafting, abdominal aortic aneurysm repair, and colectomy between 2013 and 2017. A cluster analysis was performed based on ranked scores across the 4 subthemes of the Centers for Disease Control and Prevention social vulnerability index. The likelihood of complications, extended length of stay, readmission, and mortality were assessed relative to cluster vulnerability profiles. RESULTS Among 852,449 Medicare beneficiaries undergoing surgery, median social vulnerability index among patients in the cohort was 49 (interquartile range: 24-74); cluster analysis revealed 5 vulnerability profiles that had heterogeneity in the vulnerability subthemes, even among patients with similar overall social vulnerability index scores. Postoperative outcomes differed across the 5 vulnerability profiles, with patients in the profiles characterized by higher overall vulnerability having worse postoperative outcomes. In particular, risk of complications (profile 1, 31.9% vs profile 5, 34.0%), extended length of stay (profile 1, 21.7% vs profile 5, 24.3%), 30-day readmission (profile 1, 12.6% vs profile 5, 13.2%), and 30-day mortality (profile 1, 4.0% vs profile 5, 4.7%) was greater among patients with the highest vulnerability (all P < .01). Of note, surgical outcomes varied among patients who resided in communities with similar average social vulnerability index scores (social vulnerability index 49-54). In particular, patients in social vulnerability profile 4 had 26% increased odds of 30-day mortality compared to social vulnerability profile 2 patients (odds ratio 1.26, 95% confidence interval 1.21-1.30). Additionally, profile 3 patients had 15% higher odds of 30-day mortality versus profile 2 patients (odds ratio 1.15, 95% confidence interval 1.10-1.20). CONCLUSION Postoperative outcomes differed across patients based on cluster vulnerability profiles. Despite similar overall aggregate social vulnerability index scores, cluster analysis was able to discriminate various social determinants of health subthemes among patients who resided in "average" vulnerability communities that stratified patients relative to risk of adverse postoperative events.

The aim of this analysis was to determine whether optimal outcomes have increased in recent years. Hepatic surgery is high risk, but regionalization and minimally invasive approaches have evolved. Best practices also have been defined with the goal of improving outcomes.The American College of Surgeons National Surgical Quality Improvement Program database was queried. Analyses were performed separately for partial (≤2 segments), major (≥3 segments), and all hepatectomies. Optimal hepatic surgery was defined as the absence of mortality, serious morbidity, need for a postoperative invasive procedure or reoperation, prolonged length of stay (75th percentile) or readmission. Tests of trend, χFrom 2014 to 2018, 17,082 hepatectomies, including 11,862 partial hepatectomies and 5,220 major hepatectomies, were analyzed. Minimally invasive approaches increased from 25.6% in 2014 to 29.6% in 2018 (P.01) and were performed more frequently for partial hepatectomies (34.2%) than major hepatectomies (14.4%) (P.01). Operative time decreased from 220 minutes in 2014 to 208 minutes in 2018 (P.05) and was lower in partial hepatectomies (189 vs 258 minutes for major hepatectomies) (P.01). Mortality (0.7%) and length of stay (4 days) were lower for partial hepatectomies compared with major hepatectomies (1.9%; 6 days), and length of stay decreased for both partial hepatectomies (5 days in 2014 to 4 days in 2018) and major hepatectomies (6 days in 2014 to 6 days in 2018) (all P.01). Postoperative sepsis (2.9% in 2014 and 2.4% in 2018), bile leaks (6% in 2014 and 4.8% in 2018), and liver failure (3.7% in 2014 and 3.3% in 2018) decreased for all patients (.05). On multivariable analyses, overall morbidity decreased for major hepatectomies (OR 0.95, 95% CI 0.91-0.99) and all hepatectomies (OR 0.97, 95% CI 0.94-0.99, both P.01), and optimal hepatic surgery increased over time for partial hepatectomies (OR 1.05, 95% CI 1.02-1.09) and all hepatectomies (OR 1.04, 95% CI 1.02-1.07, both P.01).Over a 5-year period in North America, minimally invasive hepatectomies have increased, while operative time, postoperative sepsis, bile leaks, liver failure, and prolonged length of stay have decreased. Optimal hepatic surgery has increased for partial and all hepatectomies and is achieved more often in partial than in major resections.

Background The objective of the current study was to assess the impact of case mix index at the hospital level on postoperative outcomes among Medicare beneficiaries who underwent hepatopancreatic surgery. Methods Medicare beneficiaries who underwent hepatopancreatic surgery between 2013 and 2017 were identified and analyzed. The primary independent variable, Case Mix Index, is a freely available metric; the primary outcome was textbook outcome defined as the absence of complications, extended length of stay, readmission, and mortality. Results Among 37,412 Medicare beneficiaries, 64.9% (n = 24,299) underwent a pancreatectomy and 35.1% (n = 13,113) underwent hepatectomy. The overall incidence of textbook outcome was 47.2%, which varied by case mix index (low case mix index: 41.6% vs high case mix index: 51.3%), as did extended length of stay (low case mix index: 27.9% versus high case mix index: 19.3%), complications (low case mix index: 33.3% vs high case mix index: 24.7%), and 90-day mortality (low case mix index: 12.5% vs high case mix index: 6.3%). After controlling for hepatopancreatic-specific surgical volume and hospital teaching status, multivariable analyses revealed that patients who underwent surgery at a low case mix index hospital had 28% decreased odds (95% confidence interval 0.66–0.79) of achieving a textbook outcome versus patients from a high case mix index hospital. Moreover, patients at a low case mix index hospital had 39% increased odds of extended length of stay (95% confidence interval 1.23–1.59), 48% increased odds of experiencing a complication (95% confidence interval 1.32–1.65), and 56% increased odds of 90-day mortality (95% confidence interval 1.31–1.87). Conclusion Case mix index was strongly associated with the probability of achieving a textbook outcome after hepatopancreatic surgery. Hospitals with a higher case mix index were more likely to perform hepatopancreatic surgeries with no adverse postoperative outcomes.

Determining the impact of county-level upward economic mobility on stage at diagnosis and receipt of treatment among Medicare beneficiaries with pancreatic adenocarcinoma.The extent to which economic mobility contributes to socioeconomic disparities in health outcomes remains largely unknown.Pancreatic adenocarcinoma patients diagnosed in 2004-2015 were identified from the SEER-Medicare linked database. Information on county-level upward economic mobility was obtained from the Opportunity Atlas. Its impact on early-stage diagnosis (stage I or II), as well as receipt of chemotherapy or surgery was analyzed, stratified by patient race/ethnicity.Among 25,233 patients with pancreatic adenocarcinoma, 37.1%(n = 9349) were diagnosed at an early stage; only 16.7%(n = 4218) underwent resection, whereas 31.7%(n = 7996) received chemotherapy. In turn, 10,073(39.9%) patients received any treatment. Individuals from counties with high upward economic mobility were more likely to be diagnosed at an earlier stage (OR 1.15, 95% CI 1.07-1.25), as well as to receive surgery (OR 1.58, 95% CI 1.41-1.77) or chemotherapy (OR 1.51, 95% CI 1.39-1.63). White patients and patients who identified as neither White or Black had increased odds of being diagnosed at an early stage (OR 1.12, 95% CI 1.02-1.22 and OR 1.35, 95% CI 1.02-1.80, respectively) and of receiving treatment (OR 1.73, 95% CI 1.59-1.88 and OR 1.49, 95% CI 1.13-1.98, respectively) when they resided in a county of high vs low upward economic mobility. The impact of economic mobility on stage at diagnosis and receipt of treatment was much less pronounced among Black patients (high vs low, OR 1.28, 95% CI 0.96-1.71 and OR 1.30, 95% CI 0.99-1.72, respectively).Pancreatic adenocarcinoma patients from higher upward mobility areas were more likely to be diagnosed at an earlier stage, as well as to receive surgery or chemotherapy. The impact of county-level upward mobility was less pronounced among Black patients.

BACKGROUND Intensive care unit (ICU) use has increased among patients with cancer. We sought to define factors associated with ICU admissions among patients with pancreatic cancer and characterize trends in mortality among hospital survivors. METHODS The Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database was used to identify patients with pancreatic cancer who underwent resection. Multivariable analyses were conducted to identify factors associated with ICU admission and mortality among hospital survivors. RESULTS Among 6422 Medicare beneficiaries who underwent resection of pancreatic cancer, 2386 (37.1%) had an ICU admission. Patients with ICU admissions were more likely to be younger (10-year increase odds ratio [OR]: 0.83, 95% confidence interval [CI]: 0.77-0.89), male (OR: 1.17, 95% CI 1.05-1.30) and undergo resection at a teaching hospital (OR: 1.19, 95% CI: 1.05-1.36). While the majority of patients survived to hospital discharge (n = 2106; 88.3%), a majority of patients (n = 1296; 54.3%) died within 6 months. Among patients who had subsequent ICU admissions, 1- and 5-year survival was only 31.8% and 11.0%, respectively. CONCLUSIONS Over one-third of patients with pancreatic cancer had an ICU admission. While most patients survived hospitalization, more than one-half of patients died within 6 months of discharge and two-thirds died within 1 year. These data should serve to guide patient-provider discussions around prognosis relative to ICU utilization.

Partial pancreatic resection is a known risk factor for new-onset pancreatogenic diabetes mellitus (P-DM). The long-term incidence of P-DM and its clinical impact after partial pancreatic resection remains unknown. The primary objective of this study is to determine the long-term incidence of P-DM and its clinical impact after partial pancreatic resection.The Medicare 100% Standard Analytic File (2013 to 2017) was queried for all patients who underwent partial pancreatic resection (pancreaticoduodenectomy, distal pancreatectomy). The primary outcome was the development of postoperative P-DM after surgery.Among 4,255 patients who underwent a pancreaticoduodenectomy or distal pancreatectomy, with a median follow-up of 10.8 months, the incidence of P-DM was 20.3% (n=863) and occurred at a median of 3.6 months after surgery. For patients with at least a 3-year follow-up, 32.2% of patients developed P-DM. Risk factors for developing P-DM included male sex (odds ratio [OR] 1.32, 95% CI 1.13 to 1.54), undergoing a distal pancreatectomy (OR 1.98, 95% CI 1.68 to 2.35), having a malignant diagnosis (OR 1.65, 95% CI 1.34 to 2.04), a family history of diabetes (OR 2.06, 95% CI 1.43 to 2.97; all p0.001), and being classified as prediabetic in the preoperative setting (OR 1.57, 95% CI 1.18 to 2.08; p = 0.002). Patients who developed P-DM were more commonly readmitted within 90 days of surgery and had higher postoperative healthcare expenditures in the year after surgery ($24,440 US dollars vs $16,130 US dollars; both p0.001) vs patients without P-DM.Approximately 1 in 5 Medicare beneficiaries who undergo a pancreatic resection develop P-DM after pancreatic resection. Appropriate screening and improved patient education should be conducted for these patients, in particular, for those with identified risk factors.

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.

In an effort to improve perioperative and oncologic outcomes, there have been multiple quality improvement initiatives, including regionalization of high-risk procedures and hospital accreditation designations from independent organizations. These initiatives may, however, hinder access to high-quality surgical care for certain patients living in areas with high social vulnerability who may be disproportionally affected, leading to disparities in access and worse postoperative outcomes.Medicare beneficiaries who underwent liver or pancreas resection for cancer were identified using the 100% Medicare Inpatient Standard Analytic Files. Hospitals were designated as high-volume based on Leapfrog criteria. The Centers for Disease Control and Prevention's social vulnerability index database was used to abstract social vulnerability index information based on each beneficiary's county of residence at the time of operation. The probability that a patient received care at a high-volume hospital stratified by the social vulnerability of the patient's county of residence was examined. Risk-adjusted postoperative outcomes were compared across low, average, and high levels of vulnerability at both low- and high-volume hospitals.Among 16,978 Medicare beneficiaries who underwent a pancreatectomy (n = 13,393, 78%) or a liver resection (n = 3,594, 21.2%) for cancer, the mean age was 73.3 years (standard deviation: 5.8), nearly half the cohort was female (n = 7,819, 46%), and the overwhelming majority were White (n = 15,034, 88.5%). Mean social vulnerability index was 49.8 (standard deviation 24.8) and mean Charlson comorbidity index was 4.8 (standard deviation: 3). Overall, 8,251 (48.6%) of patients had their operations at a high-volume hospital, and 3,802 patients had their operations at a hospital with Magnet recognition. Age and sex were similar within the low-, average-, and high-social vulnerability index cohorts (P.05); however, race differed across social vulnerability index groups. White patients made up 93% (n = 3,241) of the low social vulnerability index compared with 83.9% (n = 2,706) of the high-social vulnerability index group, whereas non-Whites made up 7% (n = 244) of the low-social vulnerability index group compared with 16.1% (n = 556) of the high-social vulnerability index group (P.001). The risk-adjusted overall probability of having surgery at a high-volume hospital decreased as social vulnerability increased (odds ratio: 0.98, 95% confidence interval: 0.97-0.99). Risk-adjusted probability of postoperative complications increased with social vulnerability index; however, among patients with high social vulnerability, risk of postoperative complications was lower at high-volume hospitals compared with low-volume hospitals. In contrast, there was no difference in postoperative complications between hospitals with and without Magnet recognition across social vulnerability index.Patients residing in communities characterized by a high social vulnerability index were less likely to undergo high-risk cancer surgery at a high-volume hospital. Although postoperative complications and mortality increased as social vulnerability index increased, some of the risk appeared to be mitigated by having surgery at a high-volume hospital. These data highlight the importance of access to high-quality surgical care, especially among patients who may already be more vulnerable.

Background The use of robotic total knee arthroplasty has become increasingly prevalent. Proponents of robotic total knee arthroplasty tout its potential to not only improve outcomes, but also to reduce costs compared with traditional total knee arthroplasty. Despite its potential to deliver on the value proposition, whether robotic total knee arthroplasty has led to improved outcomes and cost savings within Medicare’s Bundled Payment for Care Improvement initiative remains unexplored. Methods Medicare beneficiaries who underwent total knee arthroplasty designated under Medicare severity diagnosis related group 469 or 470 in the year 2017 were identified using the 100% Medicare Inpatient Standard Analytic Files. Hospitals participating in the Bundled Payment for Care Improvement were identified using the Bundled Payment for Care Improvement analytic file. We calculated risk-adjusted, price-standardized payments for the surgical episode from admission through 90-days postdischarge. Outcomes, utilization, and spending were assessed relative to variation between robotic and traditional total knee arthroplasty. Results Overall, 198,371 patients underwent total knee arthroplasty (traditional total knee arthroplasty: n= 194,020, 97.8% versus robotic total knee arthroplasty: n = 4,351, 2.2%). Among the 3,272 hospitals that performed total knee arthroplasty, only 300 (9.3%) performed robotic total knee arthroplasty. Among the 183 participating in the Bundled Payment for Care Improvement, only 40 (19%) hospitals performed robotic total knee arthroplasty. Risk-adjusted 90-day episode spending was $14,263 (95% confidence interval $14,231–$14,294) among patients who underwent traditional total knee arthroplasty versus $13,676 (95% confidence interval $13,467–$13,885) among patients who had robotic total knee arthroplasty. Patients who underwent robotic total knee arthroplasty had a shorter length of stay (traditional total knee arthroplasty: 2.3 days, 95% confidence interval: 2.3–2.3 versus robotic total knee arthroplasty: 1.9 days, 95% confidence interval: 1.9–2.0), as well as a lower incidence of complications (traditional total knee arthroplasty: 3.3%, 95% confidence interval: 3.2–3.3 versus robotic total knee arthroplasty: 2.7%, 95% confidence interval: 2.3–3.1). Of note, patients who underwent robotic total knee arthroplasty were less often discharged to a postacute care facility than patients who underwent traditional total knee arthroplasty (traditional total knee arthroplasty: 32.4%, 95% confidence interval: 32.3–32.5 versus robotic total knee arthroplasty: 16.8%, 95% confidence interval 16.1–17.6). Both Bundled Payment for Care Improvement and non-Bundled Payment for Care Improvement hospitals with greater than 50% robotic total knee arthroplasty utilization had lower spending per episode of care versus spending at hospitals with less than 50% robotic total knee arthroplasty utilization. Conclusion Overall 90-day episode spending for robotic total knee arthroplasty was lower than traditional total knee arthroplasty (Δ $–587, 95% confidence interval: $–798 to $–375). The decrease in spending was attributable to shorter length of stay, fewer complications, as well as lower utilization of postacute care facility. The cost savings associated with robotic total knee arthroplasty was only realized when robotic total knee arthroplasty volume surpassed 50% of all total knee arthroplasty volume. Hospitals participating in the Bundled Payment for Care Improvement may experience cost-saving with increased utilization of robotic total knee arthroplasty.

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.

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.

Objective The objective of the current study was to characterize the role of patient social vulnerability relative to hospital racial/ethnic integration on postoperative outcomes among patients undergoing pancreatectomy. Background The interplay between patient- and community-level factors on outcomes after complex surgery has not been well-examined. Methods Medicare beneficiaries who underwent a pancreatectomy between 2013 and 2017 were identified utilizing 100% Medicare inpatient files. P-SVI was determined using the Centers for Disease Control and Prevention criteria, whereas H-REI was estimated using Shannon Diversity Index. Impact of P-SVI and H-REI on "TO" [ie, no surgical complication/extended length-of-stay (LOS)/90-day mortality/90-day readmission] was assessed. Results Among 24,500 beneficiaries who underwent pancreatectomy, 12,890 (52.6%) were male and median age was 72 years (Interquartile range: 68-77); 10,619 (43.3%) patients achieved a TO. The most common adverse postoperative outcome was 90-day readmission (n = 8,066, 32.9%), whereas the least common was 90-day mortality (n = 2282, 9.3%). Complications and extended LOS occurred in 30.4% (n = 7450) and 23.3% (n = 5699) of the cohort, respectively. Patients from an above average SVI county who underwent surgery at a below average REI hospital had 18% lower odds [95% confidence interval (CI): 0.74-0.95] of achieving a TO compared with patients from a below average SVI county who underwent surgery at a hospital with above average REI. Of note, patients from the highest SVI areas who underwent pancreatectomy at hospitals with the lowest REI had 30% lower odds (95% CI: 0.54-0.91) of achieving a TO compared with patients from very low SVI areas who underwent surgery at a hospital with high REI. Further comparisons of these 2 patient groups indicated 76% increased odds of 90-day mortality (95% CI: 1.10-2.82) and 50% increased odds of an extended LOS (95% CI: 1.07-2.11). Conclusion Patients with high social vulnerability who underwent pancreatectomy in hospitals located in communities with low racial/ethnic integration had the lowest chance to achieve an "optimal" TO. A focus on both patient- and community-level factors is needed to ensure optimal and equitable patient outcomes.

Introduction Residential racial desegregation has demonstrated improved economic and education outcomes. The degree of racial community segregation relative to surgical outcomes has not been examined. Patients and Methods Patients undergoing pancreatic resection between 2013 and 2017 were identified from Medicare Standard Analytic Files. A diversity index for each county was calculated from the American Community Survey. Multivariable mixed-effects logistic regression with a random effect for hospital was used to measure the association of the diversity index level with textbook outcome (TO). Results Among the 24,298 Medicare beneficiaries who underwent a pancreatic resection, most patients were male (n = 12,784, 52.6%), White (n = 21,616, 89%), and had a median age of 72 (68–77) years. The overall incidence of TO following pancreatic surgery was 43.3%. On multivariable analysis, patients who resided in low-diversity areas had 16% lower odds of experiencing a TO following pancreatic resection compared with patients from high-diversity communities (OR 0.84, 95% CI 0.72–0.98). Compared with patients who resided in the high-diversity areas, individuals who lived in low-diversity areas had higher odds of 90-day readmission (OR 1.16, 95% CI 1.03–1.31) and had higher odds of dying within 90 days (OR 1.85, 95% CI 1.45–2.38) (both p < 0.05). Nonminority patients who resided in low-diversity areas also had a 14% decreased likelihood to achieve a TO after pancreatic resection compared with nonminority patients in high-diversity areas (OR 0.86, 95% CI 0.73–1.00). Conclusion Patients residing in the lowest racial/ethnic integrated counties were considerably less likely to have an optimal TO following pancreatic resection compared with patients who resided in the highest racially integrated counties.

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 effect of community-level factors on surgical outcomes has not been well examined. We sought to characterize differences in "textbook outcomes" (TO) relative to social vulnerability among Medicare beneficiaries who underwent operations for cancer.Individuals who underwent operations for lung, esophageal, colon, or rectal cancer between 2013 and 2017 were identified using the Medicare database, which was merged with the CDC's Social Vulnerability Index (SVI). TO was defined as surgical episodes with the absence of complications, extended length of stay, readmission, and mortality. The association of SVI and TO was assessed using mixed-effects logistic regression.Among 203,800 patients (colon, n = 113,929; lung, n = 70,642; rectal, n = 14,849; and esophageal, n = 4,380), median age was 75 years (interquartile range 70 to 80 years) and the overwhelming majority of patients was White (n = 184,989 [90.8%]). The overall incidence of TO was 56.1% (n = 114,393). The incidence of complications (low SVI: 21.5% vs high SVI: 24.0%) and 90-day mortality (low SVI: 7.0% vs high SVI: 8.4%) were higher among patients from highly vulnerable neighborhoods (both, p0.05). In turn, there were lower odds of achieving TO among high-vs low-SVI patients (odds ratio 0.83; 95% CI, 0.78 to 0.87). Although high-SVI White patients had 10% lower odds (95% CI, 0.87 to 0.93) of achieving TO, high-SVI non-White patients were at 22% lower odds (95% CI, 0.71 to 0.85) of postoperative TO. Compared with low-SVI White patients, high-SVI minority patients had 47% increased odds of an extended length of stay, 40% increased odds of a complication, and 23% increased odds of 90-day mortality (all, p0.05).Only roughly one-half of Medicare beneficiaries achieved the composite optimal TO quality metric. Social vulnerability was associated with lower attainment of TO and an increased risk of adverse postoperative surgical outcomes after several common oncologic procedures. The effect of high SVI was most pronounced among minority patients.

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

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.

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.

ImportanceImproving equity in organ transplant access for people with intellectual and developmental disabilities (IDD) is a topic of social discourse in mainstream media, state legislation, and national legislation. However, few studies have compared evaluation rates, transplant rates, and outcomes among adults with and without IDD.ObjectiveTo compare rates of kidney transplant and transplant-specific outcomes between propensity–score matched groups of adults with end-stage kidney disease (ESKD [also referred to as end-stage renal disease (ESRD)]) with and without co-occurring IDD.Design, Setting, and ParticipantsThis retrospective cohort study included all Medicare inpatient and outpatient standard analytical files from 2013 through 2020. A total of 1 413 655 adult Medicare beneficiaries with ESKD were identified. Propensity–score matching was used to balance cohorts based on age, sex, race, follow-up duration, and Charlson Comorbidity Index. The matched cohorts consisted of 21 384 adults with ESKD (10 692 of whom had IDD) and 1258 kidney transplant recipients (629 of whom had IDD). Data were analyzed between June 1, 2022, and August 1, 2022.ExposureIDD.Main Outcomes and MeasuresEvaluation for kidney transplant, receipt of kidney transplant, perioperative complications, readmission, mortality, graft rejection, and graft failure.ResultsOf the 21 384 propensity–score matched adults with ESKD, the median (IQR) age was 55 (43-65) years, 39.2% were male, 27.4% were Black, 64.1% were White, and 8.5% identified as another race or ethnicity. After propensity score matching within the ESKD cohort, 633 patients with IDD (5.9%) received a kidney transplant compared with 1367 of adults without IDD (12.8%). Adults with IDD were 54% less likely than matched peers without IDD to be evaluated for transplant (odds ratio, 0.46; 95% CI, 0.43-0.50) and 62% less likely to receive a kidney transplant (odds ratio, 0.38; 95% CI, 0.34-0.42). Among matched cohorts of kidney transplant recipients, rates of perioperative complications, readmission, and graft failure were similar for adults with and without IDD.Conclusions and RelevanceUsing the largest cohort of adult kidney transplant recipients with IDD to date, the study team found that rates of evaluation and transplant were lower despite yielding equivalent outcomes. These data support consideration of adults with IDD for kidney transplant and underscore the urgent need for antidiscrimination initiatives to promote the receipt of equitable care for this population.
