Racial disparities in operative outcomes after major cancer surgery in the United States

Racial and Ethnic Disparities in Emergency General Surgery Outcomes Among Older Adult Patients

INTRODUCTION

Racial and ethnic disparities in emergency general surgery (EGS) patients have been well described in the literature. Nonetheless, the burden of these disparities, specifically within the more vulnerable older adult population, is relatively unknown. This study aims to investigate racial and ethnic disparities in clinical outcomes among older adult patients undergoing EGS.

METHODS

This retrospective analysis used data from 2013 to 2019 American College of Surgeons National Surgery Quality Improvement Program database. EGS patients aged 65 y or older were included. Patients were categorized based on their self-reported race and ethnicity. The primary outcomes evaluated were in-hospital mortality, 30-d mortality, and overall morbidity. Multivariable logistic regression was performed to examine the relationship between race/ethnicity and postoperative outcomes while adjusting for relevant factors including age, comorbidities, functional status, preoperative conditions, and surgical procedure.

RESULTS

A total of 54,132 patients were included, of whom 79.8% identified as non-Hispanic White, 9.5% as non-Hispanic Black (NHB), 5.8% as Hispanic, and 4.2% as non-Hispanic Asian. After risk adjustment, compared to non-Hispanic White patients, NHB, non-Hispanic Asian, and Hispanic patients had decreased odds of 30-d mortality. For 30-d readmission and reoperation, differences among groups were comparable. However, NHB patients had significantly increased odds of overall morbidity (adjusted odds ratio, 1.18; 95% confidence interval: 1.10-1.26; P < 0.001) and postoperative complications including sepsis, venous thromboembolism, and unplanned intubation. Hispanic ethnicity was associated with lower odds of postoperative myocardial infarction and stroke.

CONCLUSIONS

Among older adult patients undergoing emergency general surgery, minority patients experienced higher morbidity rates, but paradoxical disparities in mortality were detected. Further research is necessary to identify the cause of these disparities and develop targeted interventions to eliminate them.

Postoperative racial disparities following spine surgery are less pronounced in the outpatient setting

BACKGROUND CONTEXT

Racial disparities in spine surgery have been thoroughly documented in the inpatient (IP) setting. However, despite an increasing proportion of procedures being performed as same-day surgeries, whether similar differences have developed in the outpatient (OP) setting remains to be elucidated.

PURPOSE

This study aimed to investigate racial differences in postoperative outcomes between Black and White patients following OP and IP lumbar and cervical spine surgery.

STUDY DESIGN/SETTING

Retrospective cohort study.

PATIENT SAMPLE

Patients who underwent IP or OP microdiscectomy, laminectomy, anterior cervical discectomy and fusion (ACDF), or cervical disc replacement (CDR) between 2017 and 2021.

OUTCOME MEASURES

Thirty-day rates of serious and minor adverse events, readmission, reoperation, nonhome discharge, and mortality.

METHODS

A retrospective review of patients who underwent IP or OP microdiscectomy, laminectomy, anterior cervical discectomy and fusion (ACDF), or cervical disc replacement (CDR) between 2017 and 2021 was conducted using the National Surgical Quality Improvement Program (NSQIP) database. Disparities between Black and White patients in (1) adverse event rates, (2) readmission rates, (3) reoperation rates, (4) nonhome discharge rates, (5) mortality rates, (6) operative times, and (7) hospital LOS between Black and White patients were measured and compared between IP and OP surgical settings. Multivariable logistic regression analyses were used to adjust for potential effects of baseline demographic and clinical differences.

RESULTS

Of 81,696 total surgeries, 49,351 (60.4%) were performed as IP and 32,345 (39.6%) were performed as OP procedures. White patients accounted for a greater proportion of IP (88.2% vs 11.8%) and OP (92.7% vs 7.3%) procedures than Black patients. Following IP surgery, Black patients experienced greater odds of serious (OR 1.214, 95% CI 1.077-1.370, p=.002) and minor adverse events (OR 1.377, 95% CI 1.113-1.705, p=.003), readmission (OR 1.284, 95% CI 1.130-1.459, p<.001), reoperation (OR 1.194, 95% CI 1.013-1.407, p=.035), and nonhome discharge (OR 2.304, 95% CI 2.101-2.528, p<.001) after baseline adjustment. Disparities were less prominent in the OP setting, as Black patients exhibited greater odds of readmission (OR 1.341, 95% CI 1.036-1.735, p=.026) but were no more likely than White patients to experience adverse events, reoperation, individual complications, nonhome discharge, or death (p>.050 for all).

CONCLUSIONS

Racial inequality in postoperative complications following spine surgery is evident, however disparities in complication rates are relatively less following OP compared to IP procedures. Further work may be beneficial in elucidating the causes of these differences to better understand and mitigate overall racial disparities within the inpatient setting. These decreased differences may also provide promising indication that progress towards reducing inequality is possible as spine care transitions to the OP setting.

Defining the role and impact of specialty surgeons in ensuring high-quality, accessible abdominal surgery: a report from the 2024 GI Surgery Summit

BACKGROUND

The 2024 GI Surgery Summit brought together Society for Surgery of the Alimentary Tract (SSAT), Society of Surgical Oncology (SSO), and Society of University Surgeons (SUS) members to assess the current state of gastrointestinal (GI) surgery. This report reviews the key discussions and recommendations after the dedicated plenary session that addressed challenges in providing high-quality, accessible GI surgery for all patients.

METHODS

The Summit took place from January 14 to 16. During the plenary session "Defining the role and impact of specialty surgeons in ensuring high-quality, accessible abdominal surgery," leaders, rising leaders, and members of SSAT, SSO, and SUS met and discussed challenges in providing high-quality, accessible GI surgery.

RESULTS

Actionable recommendations to address the challenges in providing high-quality, accessible GI surgical care were made, including engaging communities and patients, building alliances across hospitals and surgeons, and establishing standards of GI surgical care.

CONCLUSION

Surgeons, hospital systems, and surgical societies can improve healthcare access and outcomes for all GI surgical patients.

Racial Disparity in Length of Stay Following Implementation of a Bariatric Enhanced Recovery Program

INTRODUCTION

Enhanced Recovery Programs (ERPs) mitigate racial disparities in postoperative length of stay (LOS) for colorectal populations. It is unclear, however, if these effects exist in the bariatric surgery population. Therefore, this study aimed to evaluate the racial disparities in LOS before and after implementation of bariatric surgery ERP.

METHODS

A retrospective cohort study was performed using data from a single institution. Patients undergoing minimally invasive sleeve gastrectomy or Roux-en-Y gastric bypass from 2017 to 2019 (pre-ERP) or 2020-2022 (ERP) were included. Chi-square, Kruskal-Wallis, and analysis of variance were used to compare groups, and estimated LOS (eLOS) was assessed via multivariable regression.

RESULTS

Seven hundred sixty four patients were identified, including 363 pre-ERPs and 401 ERPs. Pre-ERP and ERP cohorts were similar in age (median 44.3 years versus 43.8 years, P = 0.80), race (53.4% Black versus 56.4% Black, P = 0.42), and preoperative body mass index (median 48.3 versus 49.4, P = 0.14). Overall median LOS following bariatric surgery decreased from 2 days pre-ERP to 1 day following ERP (P < 0.001). Average LOS for Black and White patients decreased by 0.5 and 0.48 days, respectively. However, overall eLOS remained greater for Black patients compared with White patients despite ERP implementation (eLOS 0.21 days, P = 0.01).

CONCLUSIONS

Implementation of a bariatric surgery ERP was associated with decreased LOS for both Black and White patients. However, Black patients did have slightly longer LOS than White patients in both pre-ERP and ERP eras. More work is needed to understand the driving mechanism(s) of these disparities to eliminate them.

Robot-Assisted Surgery and Racial and Ethnic Disparities in Post-Prostatectomy Outcomes Among Prostate Cancer Patients

BACKGROUND

We sought to determine whether the differences in short-term outcomes between patients undergoing robot-assisted radical prostatectomy (RARP) and those treated with open radical prostatectomy (ORP) differ by race and ethnicity.

METHODS

This observational study used New York State Cancer Registry data linked to discharge records and included patients undergoing radical prostatectomy for localized prostate cancer during 2008-2018. We used logistic regression to examine the association between race and ethnicity (non-Hispanic White [NHW], non-Hispanic Black [NHB], Hispanic), surgical approach (RARP, ORP), and postoperative outcomes (major events, prolonged length of stay [pLOS], 30-day re-admission). We tested interaction between race and ethnicity and surgical approach on multiplicative and additive scales.

RESULTS

The analytical cohort included 18,926 patients (NHW 14,215 [75.1%], NHB 3195 [16.9%], Hispanic 1516 [8.0%]). The average age was 60.4 years (standard deviation 7.1). NHB and Hispanic patients had lower utilization of RARP and higher risks of postoperative adverse events than NHW patients. NHW, NHB, and Hispanic patients all had reduced risks of adverse events when undergoing RARP versus ORP. The absolute reductions in the risks of major events and pLOS following RARP versus ORP were larger among NHB {relative excess risk due to interaction (RERI): major events -0.32 [95% confidence interval (CI) -0.71 to -0.03]; pLOS -0.63 [95% CI -0.98 to -0.35]) and Hispanic (RERI major events -0.27 [95% CI -0.77 to 0.09]; pLOS -0.93 [95% CI -1.46 to -0.51]) patients than among NHW patients. The interaction was absent on the multiplicative scale.

CONCLUSIONS

RARP use has not penetrated and benefited all racial and ethnic groups equally. Increasing utilization of RARP among NHB and Hispanic patients may help reduce disparities in patient outcomes after radical prostatectomy.

Racial differences in patient-reported outcomes among men treated with radical prostatectomy for prostate cancer

BACKGROUND

Real-world data on racial differences in the side effects of radical prostatectomy on quality of life (QoL) are lacking. We aimed to evaluate differences in patient-reported outcome measure (PROM) among non-Hispanic Black (NHB) and non-Hispanic White (NHW) men using the Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) questionnaire to measure health-related QoL after radical prostatectomy.

METHODS

We retrospectively assessed prospectively collected PROMs using EPIC-CP scores at a tertiary care center between 2015 and 2021 for men with prostate cancer undergoing radical prostatectomy. The primary endpoint was the overall QoL score for NHB and NHW men, with a total score of 60 and higher scores indicating worse QoL. An imputed mixed linear regression model was used to examine the effect of covariates on the change in overall QoL score following surgery. A pairwise comparison was used to estimate the mean QoL scores before surgery as well as up to 24 months after surgery.

RESULTS

Our cohort consisted of 2229 men who answered at least one EPIC-CP questionnaire before or after surgery, of which 110 (4.94%) were NHB and 2119 (95.07%) were NHW men. The QoL scores differed for NHB and NHW at baseline (2.34, 95% confidence interval [CI] 0.36-4.31, p = 0.02), 3 months (4.36, 95% CI 2.29-6.42, p < 0.01), 6 months (3.26, 95% CI 1.10-5.43, p < 0.01), and 12 months after surgery (2.48, 95% CI 0.19-4.77, p = 0.03) with NHB having worse scores. There was no difference in QoL between NHB and NHW men 24 months after surgery.

CONCLUSIONS

A significant difference in QoL between NHB and NHW men was reported before surgery, 3, 6, and 12 months after surgery, with NHB having worse QoL scores. However, there was no long-term difference in reported QoL. Our findings inform strategies that can be implemented to mitigate racial differences in short-term outcomes.

Investigating Mortality Disparities Among Insured Patients With Colon Cancer Treated in an Integrated Health care System and Other Private Settings

BACKGROUND

Lower socioeconomic status (SES) affects health care delivery and is associated with worse outcomes. Integrated healthcare systems (IHS) may help reduce barriers to health care and affect outcomes. Our aim was to compare outcomes of colon cancer cases diagnosed at the largest IHS in California, Kaiser Permanente Southern California (KPSC), to other insured patients (OI) to determine how SES influences mortality.

METHODS

This retrospective cohort study included insured adults in southern California diagnosed with colon cancer between 2009 and 2014, using data from the California Cancer Registry, and followed through 2017. Main outcome was all-cause mortality. Person-year mortality rates were calculated for two groups, KPSC and OI. Multivariable hazard ratios were calculated for association between SES quintiles and mortality.

RESULTS

Total of 15 923 patients were diagnosed with colon cancer, 4195 patients (26.3%) within KPSC and 11 728 patients (73.7%) in OI. The overall mortality rate per 1000 person-years (PY) was lower in KPSC [103.8/1000 PY (95% CI:98.5-109.3)] compared to OI [139.3/1000 PY (95% CI:135.2-143.4)]. Compared to the highest SES group, the lowest SES group did not experience higher mortality risk in the KPSC population, after adjusting for race/ethnicity and other factors (HR, 95% CI = 1.13, .93-1.38). However, in OI patients, lowest and lower-middle SES groups had higher mortality risk compared to the highest SES group (HR, 95% CI = 1.26, 1.13-1.40 and 1.28, 1.16-1.41, respectively).

DISCUSSION

Lower SES was associated with higher mortality risk within the OI group; however, within KPSC no such association was observed. Care coordination in IHS settings mitigate SES-related mortality differences.

The combined effect of race, dual-eligibility and neighborhood deprivation on medicare spending after cancer surgery

INTRODUCTION

Disparities in clinical outcomes following high-risk cancer operations are well documented, but, whether these disparities contribute to higher Medicare spending is unknown.

METHODS

Using 100% Medicare claims, White and Black beneficiaries undergoing complex cancer surgery between 2016 and 2018 with dual eligibility status and census tract Area Deprivation Index score were included. Linear regression was used to assess the association of race, dual-eligibility, and neighborhood deprivation on Medicare payments.

RESULT

Overall, 98,725 White(93.5%) and 6900 Black(6.5%) patients were included. Black beneficiaries were more likely to live in the most deprived neighborhoods(33.4% vs. 13.6%; P < 0.001) and be dual-eligible(26.6% vs. 8.5%; P < 0.001) compared to White beneficiares. Overall, Medicare spending was higher for Black compared to White patients($27,291 vs. 26,465; P < 0.001). Notably, when comparing Black dual-eligible patients living in the most deprived neighborhoods to White non-dual eligible patients living in the least deprived spending($29,507 vs. $25,596; abs diff $3911; P < 0.001).

CONCLUSION

In this study, Medicare spending was significantly higher for Black patients undergoing complex cancer operations compared to White patients due to higher index hospitalization and post-discharge care payments.

Race and Ethnicity Impacts Overall Survival of Patients with Appendiceal Cancer Who Undergo Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy

Appendiceal cancer treatment may include cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC). We investigated whether patient race/ethnicity influences outcomes and overall survival for patients with appendiceal cancer who undergo CRS/HIPEC. We queried the National Cancer Database for adult patients with appendiceal cancer treated with CRS/HIPEC from 2006 to 2018. Patients were stratified by race/ethnicity: non-Hispanic White (NHW), non-Hispanic Black (NHB), Hispanic, and Other. Sociodemographics and outcomes were compared using descriptive statistics. Kaplan-Meier survival analysis and Log-rank tests assessed differences in overall survival (OS). Cox Multivariate Regression evaluated factors associated with OS. In total, 2532 patients were identified: 2098 (82.9%) NHW, 186 (7.3%) NHB, 127 (5.0%) Hispanic, and 121 (4.8%) Other patients. The sociodemographics were statistically different across groups. The perioperative and postoperative outcomes were similar. OS was significantly different by race/ethnicity (p = 0.0029). NHB patients compared to Hispanic patients had the shortest median OS (106.7 vs. 145.9 months, p = 0.0093). Race/ethnicity was independently associated with OS: NHB (HR: 2.117 [1.306, 3.431], p = 0.0023) and NHW (HR: 1.549 [1.007, 2.383], p = 0.0463) patients compared to Hispanic patients had worse survival rates. Racial/ethnic disparities exist for patients with appendiceal cancer undergoing CRS/HIPEC. Despite having similar tumor and treatment characteristics, OS is associated with patient race/ethnicity.

Racial Disparities in General Surgery Outcomes

INTRODUCTION

While disparities in Black and Hispanic and Latino patients undergoing general surgeries are well described, most analyses leave out Asian, American Indian or Alaskan Native (AIAN), and native Hawaiian or Pacific Islander patients. This study identified general surgery outcomes for each racial group in the National Surgical Quality Improvement Program.

METHODS

National Surgical Quality Improvement Program was queried to identify all procedures conducted by a general surgeon from 2017 to 2020 (n = 2,664,197). Multivariable regression models were used to investigate the impact of race and ethnicity on 30-day mortality, readmission, reoperation, major and minor medical complications, and non-home discharge destinations. Adjusted odds ratios (AOR) and 95% confidence intervals were calculated.

RESULTS

Compared to non-Hispanic White patients, Black patients had higher odds of readmission and reoperation, and Hispanic and Latino patients had higher odds of major and minor complications. AIAN patients had higher odds of mortality (AOR: 1.003 (1.002-1.005), P < 0.001), major complication (AOR: 1.013 (1.006-1.020), P < 0.001), reoperation (AOR: 1.009, (1.005-1.013), P < 0.001), and non-home discharge destination (AOR: 1.006 (1.001-1.012), P = 0.025), while native Hawaiian or Pacific Islander patients had lower odds of readmission (AOR: 0.991 (0.983-0.999), P = 0.035) and non-home discharge destination (AOR: 0.983 (0.975-0.990), P < 0.001) compared to non-Hispanic White patients. Asian patients had lower odds of each adverse outcome.

CONCLUSIONS

Black, Hispanic and Latino, and AIAN patients are at higher odds for poor postoperative results than non-Hispanic White patients. AIANs had some of the highest odds of mortality, major complications, reoperation, and non-home discharge. Social health determinants and policy adjustments must be targeted to ensure optimal operative results for all patients.

A Comparison of Whipple Outcomes Between a Safety-Net Hospital and American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) in African Americans

Purpose The aim of this study was to compare 30-day adverse events following pancreaticoduodenectomy between our safety-net hospital and the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) in a matched cohort of Black/African American (AA) patients. Methods We retrospectively reviewed consecutive Black/AA patients undergoing pancreaticoduodenectomies from 2015 to 2020 at our safety-net institution. The corresponding patients from the ACS-NSQIP (2015-2019) were queried. Propensity-score matching was performed between safety-net and ACS-NSQIP Black/AA cohorts to equate baseline characteristics, and 30-day outcomes were compared between propensity-matched cohorts. Results Thirty-two Black/AAs (16 females; 62.1±10.7 years) were identified from 128 patients undergoing pancreaticoduodenectomies at our safety-net institution and were propensity-score matched to 32 ACS-NSQIP patients. After matching, baseline characteristics did not significantly differ between cohorts. Postoperatively, surgical site infections, wound disruptions, respiratory events, cardiovascular events, urinary tract infections, acute renal failure, sepsis, delayed gastric emptying, and pancreatic fistulas were not significantly different between our safety-net and ACS-NSQIP cohorts. Our length of stay (LOS) was longer (17.0(12.3-27.0) versus 10.0(7.0-16.0) days); however, patients with a LOS>30 days were comparable. Furthermore, 30-day readmissions were similar, and 30-day reoperations were lower (p=0.03) at our safety-net institution. Conclusions Black/AA patients who underwent pancreatectomies at a safety-net hospital had similar outcomes and fewer reoperations compared to a corresponding national cohort. Although we illustrate comparable outcomes, clinical pathways to mitigate and alleviate health disparities in marginalized populations at a safety-net hospital should be emphasized to continue improving outcomes.

Comparisons between White and Black Patients Hospitalized with Postliver Transplant Complications/Failure

OBJECTIVES

The impact of race on patients presenting to North American hospitals with postliver transplant complications/failure (PLTCF) has not been studied fully. We compared in-hospital mortality and resource utilization outcomes between White and Black patients hospitalized with PLTCF.

METHODS

This was a retrospective cohort study that evaluated the years 2016 and 2017 from the National Inpatient Sample. Regression analysis was used to determine in-hospital mortality and resource utilization.

RESULTS

There were 10,805 hospitalizations for adults with liver transplants who presented with PLTCF. White and Black patients with PLTCF made up 7925 (73.3%) hospitalizations from this population. Among this group, 6480 were White (81.7%) and 1445 were Black (18.2%). Blacks were younger than Whites (mean age ± standard error of the mean: 46.8 ± 1.1 vs 53.6 ± 0.39 years, P < 0.01). Blacks were more likely to be female (53.9% vs 37.4%, P < 0.01). Charlson Comorbidity Index scores were not significantly different (scores ≥3: 46.7% vs 44.2%, P = 0.83). Blacks had significantly higher odds for in-hospital mortality (adjusted odds ratio 2.9, confidence interval [CI] 1.4-6.1; P < 0.01). Hospital charges were higher for Blacks compared with Whites (adjusted mean difference $48,432; 95% CI $2708-$94,157, P = 0.03). Blacks had significantly longer lengths of hospital stays (adjusted mean difference 3.1 days, 95% CI 1.1-5.1, P < 0.01).

CONCLUSIONS

Compared with White patients hospitalized for PLTCF, Black patients had higher in-hospital mortality and resource use. Investigation into causes leading to this health disparity is needed to improve in-hospital outcomes.

Racial Disparities in Perioperative Morbidity Following Oncological Spine Surgery

STUDY DESIGN

Retrospective cohort study.

OBJECTIVE

To assess the impact of race on complications following spinal tumor surgery.

METHODS

Adults with cancer who underwent spine tumor surgery were identified in the American College of Surgeons National Surgical Quality Improvement Program datasets from 2012 to 2016. Clavien-Dindo Grade I-II (minor complications) and Clavien-Dindo Grade III-V (major complications including 30-day mortality) complications were compared between non-Hispanic Whites (NHW) and Black patients. A multivariable analysis was also conducted.

RESULTS

Of 1,226 identified patients, 85.9% were NHW (n = 1,053) and 14.1% were Black (n = 173). The overall rate of Grade I-II complications was 16.2%; 15.1% for NHW patients and 23.1% for Black patients (P = .008). On multivariable analysis, Black patients had significantly higher odds of having a minor complication (OR 1.87; 95% CI, 1.16-3.01; P = .010). On the other hand, the overall rate of Grade III-V complications was 13.3%; 12.5% for NHW patients and 16.2% for Black patients (P = .187). On multivariable analysis, Black race was not independently associated with major complications (OR 1.26; 95% CI, 0.71-2.23; P = .430). Median length of stay was 8 days (IQR 5-13) for NHW patients and 10 days (IQR 6-15) for Black patients (P = .011).

CONCLUSION

Black patients who underwent metastatic spinal tumor surgery were at a significantly increased risk of perioperative morbidity compared to NHW patients independent of baseline and operative characteristics. Major complications did not differ between groups. Race should be further studied in the context of metastatic spine disease to improve our understanding of these disparities.

Hysterectomy inequities between black and white patients in the US military health system: A retrospective cohort study

OBJECTIVE

To evaluate multicomponent aspects of hysterectomy-related care in the US Military Health System including the probability of open hysterectomy (versus vaginal or laparoscopic hysterectomy), probability of having a length of stay > 1 day, and discharge milligram morphine equivalent dose (MED). Analyses sought to identify the presence and strength of healthcare inequities between Black and white patients.

METHODS

In this retrospective cohort study, records of patients (N = 11,067) ages 18-65 years enrolled in TRICARE who underwent a hysterectomy between January 2017 to January 2021 in US military treatment facilities (direct care) or civilian facilities (purchased care) were included. Graphic representations illustrated provider and facility variation. Generalized additive mixed models (GAMMs) evaluated inequities across outcomes. Sensitivity analyses included only direct care receipt and added a random effect for the facility.

RESULTS

There was significant variation in provider use of open versus vaginal or laparoscopic hysterectomies, as well as provider and facility discharge MED. The GAMMs indicated Black patients were more likely to receive an open hysterectomy [log(OR) -0.54, (95 %CI -0.65, -0.43), p < 0.001] and have a length of stay > 1 day [log(OR) 0.18, (95 %CI 0.07, 0.30), p = 0.002], but had similar discharge MED [-2 mg (95% CI -7 mg, 3 mg), p = 0.51], relative to white patients. Patients receiving care in purchased care, relative to direct care, were more likely to receive a vaginal or laparoscopic hysterectomy [log(OR) 0.28, (95 %CI 0.17, 0.38), p = 0.002] and received approximately 21 mg lower discharge MED (95 %CI 16-26 mg less, p < 0.001), but were more likely to have a hospital stay > 1 day [log(OR) 0.95, (95 %CI 0.83, 0.1.10), p < 0.001]. Additional gynecological conditions (e.g., uterine fibroids) and prescription receipt were associated with some, but not all outcomes.

CONCLUSION

Improving timely care receipt, especially for uterine fibroids, increasing access to vaginal and laparoscopic hysterectomies, and reducing unwarranted variation in discharge MED could improve care quality and equity in the US Military Health System.

Hospital-Level Segregation Among Medicare Beneficiaries Undergoing Lung Cancer Resection

BACKGROUND

Recent research has raised concern that health care segregation, the high concentration of racial groups within a subset of hospitals, is a key contributor to persistent disparities in surgical care. However, to date the extent and effect of hospital level segregation among patients undergoing resection for lung cancer remains unclear.

METHODS

We used 100% Medicare fee-for-service claims to evaluate the degree of hospital-level racial segregation for patients undergoing resection for lung cancer between 2014 and 2018. Hospitals serving a high volume of minority patients were defined as the top decile of hospitals by volume of racial and ethnic minority beneficiaries served. Multivariable logistic regression analysis was used to compare surgical outcomes between hospitals serving high vs low volumes of minority patients.

RESULTS

A total of 122,943 patients were included, with racial/ethnic composition of 360 American Indian or Native American (0.3%), 2077 Asian or Pacific Islander (1.7%), 1146 Hispanic or Latino (0.9%), 8707 non-Hispanic Black (7.1%), and 108,665 non-Hispanic White patients. Overall, 31.6%, 15.9%, 15.0%, and 7.8% of all hospitals performed 90% of lung cancer resection for Black, Asian, Hispanic, and Native American patients, respectively. Hospitals performing higher volumes of operations for racial and ethnic minorities had higher mortality (3.9% vs 3.1%; odds ratio [OR], 1.19; 95% CI, 1.15-1.23; P < .001), complications (18.1% vs 15.9%; OR, 1.17; 95% CI, 1.14-1.19; P < .001), and readmissions (11.7% vs 11.2%; OR, 1.04; 95% CI, 1.02-1.05; P < .001) for resections for lung cancer.

CONCLUSIONS

Our findings suggest that a small proportion of hospitals provide a disproportionate amount of surgical care for racial and ethnic minorities with lung cancer with inferior surgical outcomes.

Disparities in Receipt of Adjuvant Therapy After Upfront Surgical Resection for Pancreatic Ductal Adenocarcinoma

BACKGROUND

A multimodal approach of surgery and chemotherapy, with or without radiation, is the mainstay of therapy with curative-intent for resectable pancreatic ductal adenocarcinoma (PDAC). This study compared utilization trends and outcomes of upfront surgery with and without adjuvant therapy.

METHODS

The National Cancer Database was queried for patients with a diagnosis of stage 1 or 2 PDAC who underwent upfront resection. Multivariable regression was applied to identify factors associated with initiation of adjuvant therapy.

RESULTS

Of the 39,128 patients in the study, 67% initiated adjuvant therapy after resection, whereas 33% received upfront surgery alone. Receipt of adjuvant multimodal therapy increased from 59% in 2006 to 69% in 2017 (P < 0.0001). Non-white race was associated with lower odds of receiving adjuvant therapy after adjustment for income status, education attainment, and other variables (Hispanic/Spanish [odds ratio {OR}, 0.77; 95% confidence interval {CI}, 0.69-0.86] and non-Hispanic black [OR 0.84; 95% CI 0.78-0.91 vs non-Hispanic white; P < 0.001). The variables that contributed to receipt of adjuvant therapy were place of residence in high versus low education attainment area (OR 1.30; 95% CI 1.18-1.44; P < 0.0001) and lower odds for initiation of adjuvant therapy with increasing distance from the treating facility (> 50 miles [OR 0.51; 95% CI 0.47-0.54] vs <12.5 miles; P < 0.0001). The median unadjusted overall survival (OS) time was 18.2 months (95% CI 17.7-18.8 months) for upfront surgery alone and 25.3 months (95% CI 24.9-25.8 months) for surgery with adjuvant therapy.

CONCLUSIONS

The patients who underwent upfront surgical resection for PDAC showed wide socioeconomic disparities in the use of adjuvant therapy independent of insurance status, facility type, or travel distance.

Fecal continence outcomes and potential disparities for patients with anorectal malformations treated at referral institutions for pediatric colorectal surgery

PURPOSE

Fecal incontinence is a problem for many patients born with an anorectal malformation (ARM) that can impact quality of life. It is unknown if racial, ethnic, and socioeconomic disparities relate to fecal continence in these children. We sought to examine outcomes and potential disparities in care.

METHODS

We performed a multicenter retrospective study of children > 3y with ARM evaluated at sites participating in the Pediatric Colorectal and Pelvic Learning Consortium (PCPLC). The primary outcome was fecal continence. We evaluated for associations between fecal continence and race, sex, age, and insurance status.

RESULTS

509 patients with ARM from 11 institutions were included. Overall, 24% reported complete fecal continence, and fecal continence was associated with older age (p < .001). For school-aged children, 27% reported complete continence, while 53% reported none. On univariate analysis, patients with combined private and public insurance showed lower rates of continence when compared to those with private insurance (23 vs. 12%; p = 0.02). Age was associated with continence on univariate and multivariable analyses.

CONCLUSION

Rates of complete fecal continence in this population are low. Differences based on payor status may exist. There were no observed disparities related to sex and race. Further investigation is warranted to improve care for this patient population.

Small bowel obstruction in older patients: challenges in surgical management

BACKGROUND

Small bowel obstruction (SBO) is a common disease affecting all segments of the population, including the frail elderly. Recent retrospective data suggest that earlier operative intervention may decrease morbidity. However, management decisions are influenced by surgical outcomes. Our goal was to determine the current surgical management of SBO in older patients with particular attention to frailty and the timing of surgery.

STUDY DESIGN

A retrospective review of patients over the age of 65 with a diagnosis of bowel obstruction (ICD-10 K56*) using the 2016 National Inpatient Sample (NIS). Demographics included age, race, insurance status, medical comorbidities, and median household income by zip code. Elixhauser comorbidities were used to derive a previously published frailty score using the NIS dataset. Outcomes included time to operation, mortality, discharge disposition, and hospital length of stay. Associations between demographics, frailty, timing of surgery, and outcomes were determined.

RESULTS

264,670 patients were included. Nine percent of the cohort was frail; overall mortality was 5.7%. Frail had 1.82 increased odds of mortality (95% CI 1.64-2.03). Hospital LOS was 1.6 times as long for frail patients; a quarter of the frail were discharged home. Frail patients waited longer for surgery (3.58 days vs 2.44 days; p < 0.001). Patients transferred from another facility had increased mortality (aOR 1.58; 95% CI 1.36-1.83). There was an increasing mortality associated with a delay in surgery.

CONCLUSION

Patients with frailty and SBO have higher mortality, more frequent discharge to dependent living, longer hospital length of stay, and longer wait to operative intervention. Mortality is also associated with male gender, black race, transfer status from another facility, self-pay status, and low household income. Every day in delay in surgical intervention for those who underwent operations led to higher mortality. If meeting operative indications, older patients with bowel obstruction have a higher chance of survival if they undergo surgery earlier.

Racial Disparities in Surgical Outcomes Among Women with Endometrial Cancer

PURPOSE

Endometrial cancer (EC) is the most common gynecological cancer among women in the United States. Despite well-documented racial/ethnic disparities in EC incidence and mortality rates, limited data exist regarding disparities in hysterectomy surgical outcomes. We evaluated associations of race/ethnicity with postoperative complications, serious adverse events (SAEs), and length of hospital stay among women undergoing EC-related hysterectomy.

METHODS

Using National Surgical Quality Improvement Program (NSQIP) data, we identified women (≥18 years) undergoing hysterectomy to treat EC between 2014 and 2020. We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for associations of race/ethnicity (white, black, and Latina) with postoperative complications and SAEs. We used Poisson regression with robust standard errors to calculate incidence rate ratios (IRRs) and 95% CIs for the association of race/ethnicity with length of hospital stay.

RESULTS

Of 22,778 women undergoing EC-related hysterectomy, 3.1% developed postoperative complications. Black (adjusted OR: 1.62; 95% CI 1.05-2.48) and Latina women (adjusted OR: 1.79; 95% CI 1.04-3.09) had higher postoperative complication risks than white women. The overall SAE incidence was 5.0%. Black women (adjusted OR: 1.55, 95% CI 1.13-2.15) had higher SAE risks than white women. Length of hospital stay was significantly longer for black women than white women (IRR: 1.18; 95% CI 1.07-1.30).

CONCLUSIONS

We observed racial/ethnic disparities in EC-related hysterectomy surgical outcomes in a large, diverse sample of U.S. women between 2014 and 2020. Studies to elucidate the underlying mechanisms of these racial disparities, with a focus on social context remain necessary.

Characterizing the Association of Race and Insurance Status with Resource Utilization in Brachial Plexopathy Surgery

BACKGROUND

Understanding the link between socioeconomic status and immediate postoperative brachial plexus injury (BPI) management outcomes is critical to mitigating disparities and optimizing postoperative recovery plans. The present study aimed to elucidate the association between socioeconomic status and resource utilization following surgery for BPI.

METHODS

We conducted a cross-sectional study of adult patients (18 years) with a BPI diagnosis from the 2002-2017 National Inpatient Sample. Primary outcomes included home discharge rates, length of stay (LOS), and cost. We used multivariable regressions to analyze outcome measures.

RESULTS

A total of 23,755 BPI admissions were identified, 14.67% of whom received surgical intervention. Patients receiving Medicare had lower odds of home discharge compared with privately insured patients (adjusted odds ratio 0.65, 95% confidence interval 0.58-0.74; P < 0.001). Medicaid, Medicare, and uninsured patients had 6%-32% longer LOS than privately insured patients (P < 0.001, P = 0.004, and P = 0.006, respectively). Patients in the top income quartile had a 12% increase in costs compared with those in the bottom quartile (P < 0.001). Latinx and Other race groups had 11%-14% increased costs compared with White patients (Latinx P < 0.001, Other P = 0.003).

CONCLUSIONS

Differences in BPI resource utilization and allocation exist, from increased LOS among non-privately insured and non-White patients to increased BPI treatment costs among patients in higher-income quartiles. Further research is necessary to elucidate how these disparities exist and impact functional outcomes.

Temporal trends in Black-White disparities in cancer surgery and cancer-specific survival in the United States between 2007 and 2015

BACKGROUND

The American Society of Clinical Oncology (ASCO) has strived to address racial/ethnic disparities in cancer care since 2009. Surgery plays a pivotal role in cancer care; however, it is unclear whether and how racial/ethnic disparities in cancer surgery have changed over time.

METHODS

This cohort study included 1,113,256 White and Black cancer patients across 9 years (2007-2015) using patient data extracted from the Surveillance, Epidemiology, and End Results (SEER)-18 registries. Patient data were included from 2007 to adjust insurance status and by 2015 to obtain at least a 3-year survival follow-up (until 2018). The primary outcome was a surgical intervention. The secondary outcomes were the use of (neo)adjuvant chemotherapy and cancer-specific survival (CSS). Adjusted associations of the race (Black/White) with the outcomes were measured in each cancer type and year.

RESULTS

The gap between surgery rates for Black and White patients narrowed overall, from an adjusted odds ratio (aOR) of 0.621 (0.592-0.652) in 2007 to 0.734 (0.702-0.768) in 2015. However, the racial gap persisted in the surgery rates for lung, breast, prostate, esophageal, and ovarian cancers. In surgically treated patients with lymph node metastasis, Black patients with colorectal cancer (CRC) were less likely to receive (neo)adjuvant chemotherapy than White patients. Black patients undergoing surgery were more likely to have a worse CSS rate than White patients undergoing surgery. In breast cancer patients, the overall trend was narrow, but continuously present, with an adjusted hazard ratio (aHR) of 1.224 (1.278-1.173) in 2007 and 1.042 (1.132-0.96) in 2015.

CONCLUSIONS

Overall, progress has been made toward narrowing the Black-White gap in cancer surgical opportunity and survival. Future efforts should be directed toward those specific cancers for which the Black-White gap continues. Additionally, it is worth addressing the Black-White gap regarding the use of (neo)adjuvant chemotherapy for CRC treatment.

Racial Disparities in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy: Does Aggressive Surgical Treatment Overcome Cancer Health Inequities?

Background

Advanced cancer states perpetuate health-related disparities. Peritoneal-based cancers are clinically advanced cancers that present a significant clinical dilemma. Peritoneal cancers are managed aggressively with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). While racial and ethnic disparities are prevalent in cancer, there are no studies investigating if racial disparities exist in patients with peritoneal carcinomatosis managed with CRS and HIPEC. We hypothesized that this advanced disease state further delineates racial disparities.

Methods

A retrospective chart review was conducted on patients with peritoneal carcinomatosis receiving CRS and HIPEC at a single institution from January 1, 2017-October 4, 2021. Descriptive statistics were used to compare racial groups. The Cox Proportional Hazards Model and Log Rank Test were used for multivariate and overall survival analysis.

Results

In total, 67 patients underwent CRS and HIPEC, of which 41 (61.2%) were White, 20 (29.8%) were Black, 3 (4.5%) were Asian, and 3 (4.5%) were Other race. When compared to White patients, Black patients had lower income (p=0.0011), higher incidence of hypertension (p=0.0231), and lower performance status (p=0.0441). Cancer type, including colorectal, appendiceal, ovarian, etc., was similar between groups (p=0.8703). Despite these differences in sociodemographic and morbidity factors, when comparing Black patients to White patients, there were no differences in peritoneal cancer index score (13.2 vs. 12.3, p=0.6932), estimated blood loss (748 vs. 655 mL, p=0.6332), minor/major complication rates (1.1 vs. 1.2, p=0.7281; 0.4 vs. 0.7, p=0.3470, respectively), 30-day readmission rates (25.0% vs. 17.1%, p=0.6210), disease recurrence (40.0% vs. 51.2%, p=0.3667), or 30-day mortality (0.0% vs. 2.4%, p=1.0000). Overall survival was similar for Black and White patients (p=0.2693). The occurrence of a major complication was the only factor associated with overall survival (HR 2.188 [1.502, 3.188], p< 0.0001).

Conclusions

Despite differences in patient socioeconomic factors and comorbid conditions, outcomes were similar between Black and White patients receiving CRS and HIPEC at our institution. While larger studies with more diverse patient populations are needed to confirm these findings, our data provide evidence that aggressive surgical management across diverse patient populations allows for equitable outcomes.

Patients undergoing colorectal surgery at a Veterans Affairs Hospital do not experience racial disparity in length of stay either before or after implementing an enhanced recovery pathway

Background

Enhanced Recovery Pathways (ERP) have been shown to reduce racial disparities following surgery. The objective of this study is to determine whether ERP implementation mitigates racial disparities at a Veterans Affairs Hospital.

Methods

A retrospective cohort study was conducted using data obtained from the Veterans Affairs Surgical Quality Improvement Program. All patients undergoing elective colorectal surgery following ERP implementation were included. Current procedural terminology (CPT) codes were used to identify patients who underwent similar procedures prior to ERP implementation.

Results

Our study included 417 patients (314 pre-ERP vs. 103 ERP), 97.1% of which were male, with an average age of 62.32 (interquartile range (IQR): 25–90). ERP patients overall had a significantly shorter post-operative length of stay (pLOS) vs. pre-ERP patients (median 4 days (IQR: 3–6.5) vs. 6 days (IQR: 4–9) days (p < 0.001)). Within the pre-ERP group, median pLOS for both races was 6 days (IQR: 4–6; p < 0.976) and both groups experienced a decrease in median pLOS (4 vs. 6 days; p < 0.009 and p < 0.001) following ERP implementation.

Conclusions

Racial disparities did not exist in patients undergoing elective surgery at a single VA Medical Center. Implementation of an ERP significantly reduced pLOS for black and white patients.

Racial and Ethnic Disparities in Surgical Outcomes after Postmastectomy Breast Reconstruction

BACKGROUND

Women of color with breast cancer are less likely to undergo post-mastectomy reconstruction compared with White women, but it is unclear whether their perioperative outcomes are worse. The goal of this study was to investigate differences in preoperative comorbidities and postoperative complications by race/ethnicity among women with breast cancer undergoing postmastectomy reconstruction.

STUDY DESIGN

Data were collected from the National Inpatient Sample database of the Healthcare Cost and Utilization Project from 2012 to 2016. Patient demographics, types of reconstruction, comorbid conditions, Charlson-Deyo Combined Comorbidity (CDCC) scores, length of stay (LOS), and perioperative complications were abstracted. Multivariate linear and logistic regression were performed to model LOS and likelihood of postoperative complications, respectively.

RESULTS

Compared with White women (n = 19,730), Black women (n = 3,201) underwent autologous reconstruction more frequently (40.7% vs 28.3%), had more perioperative comorbidities (eg diabetes: 12.9% vs 5.8%), higher CDCC scores (% CDCC ≥ 4: 5.5% vs 2.7%), and longer LOS (median 3 vs 2 days, all p < 0.001). Being Black (vs White: +0.13 adjusted days, 95% CI 0.06 to 0.19) was also associated with longer LOS and an increased likelihood of surgical complications (vs White: odds ratio 1.24, 95% CI 1.09 to 1.42, both p < 0.01), but this association did not persist when outcomes were limited to microsurgical complications.

CONCLUSION

Disparities in postmastectomy breast reconstruction between Black and White women extend beyond access to care and include perioperative factors and outcomes. These findings suggest an important opportunity to mitigate inequities in reconstruction through perioperative health optimization and improved access to and co-management with primary care.

Racial Disparities in 30-Day Outcomes After Colorectal Surgery in an Integrated Healthcare System

BACKGROUND

Racial disparities in colorectal surgery outcomes have been studied extensively in the USA, and access to healthcare resources may contribute to these differences. The Veterans Health Administration (VHA) is the largest integrated healthcare network in the USA with the potential for equal access care to veterans. The objective of this study is to evaluate the VHA for the presence of racial disparities in 30-day outcomes of patients that underwent colorectal resection.

METHODS

Colon and rectal resections from 2008 to 2019 were reviewed retrospectively using the Veterans Affairs Surgical Quality Improvement Program database. Patients were categorized by race and ethnicity. Multivariable analysis was used to compare 30-day outcomes. Cases with "unknown/other/declined to answer" race/ethnicity were excluded.

RESULTS

Thirty-six-thousand-nine-hundred-sixty-nine cases met inclusion criteria: 27,907 (75.5%) Caucasian, 6718 (18.2%) African American, 2047 (5.5%) Hispanic, and 290 (0.8%) Native American patients. There were no statistically significant differences in overall complication incidence or mortality between all cohorts. Compared to Caucasian race, African American patients had longer mean length of stay (10.7 days vs. 9.7 days; p < 0.001). Compared to Caucasian race, Hispanic patients had higher odds of pulmonary-specific complications (adjusted odds ratio with 95% confidence interval = 1.39 [1.17-1.64]; p < 0.001).

CONCLUSIONS

The VHA provides the benefits of integrated healthcare and access, which may explain the improvements in racial disparities compared to existing literature. However, some racial disparities in clinical outcomes still persisted in this analysis. Further efforts beyond healthcare access are needed to mitigate disparities in colorectal surgery.

Opioid Use Disorder is Associated With Complications and Increased Length of Stay After Major Abdominal Surgery

OBJECTIVE

The objective of this study was to determine the impact of opioid use disorder (OUD) on perioperative outcomes after major upper abdominal surgeries.

SUMMARY OF BACKGROUND DATA

OUD, defined as dependence/abuse, is a national health epidemic. Its impact on outcomes after major abdominal surgery has not been well characterized.

METHODS

Patients who underwent elective esophagectomy, total/partial gastrectomy, major hepatectomy, and pancreatectomy were identified using the National Inpatient Sample (2003-2015). Propensity score matching by baseline characteristics was performed for patients with and without OUD. Outcomes measured were in-hospital complications, mortality, length of stay (LOS), and discharge disposition.

RESULTS

Of 376,467 patients, 1096 (0.3%) had OUD. Patients with OUD were younger (mean 53 vs 61 years, P < 0.001) and more often male (55.1% vs 53.2%, P < 0.001), black (15.0% vs 7.6%, P < 0.001), Medicaid beneficiaries (22.0% vs 6.4%, P < 0.001), and in the lowest income quartile (32.6% vs 21.3%, P < 0.001). They also had a higher rate of alcohol (17.2% vs 2.8%, P < 0.001) and nonopioid drug (2.2% vs 0.2%, P = 0.023) dependence/abuse. After matching (N = 1077 OUD, N = 2164 no OUD), OUD was associated with a higher complication rate (52.9% vs 37.3%, P < 0.001), including increased pain [odds ratio (OR) 3.5, P < 0.001], delirium (OR 3.0, P = 0.004), and pulmonary complications (OR 2.0, P = 0.006). Additionally, OUD was associated with increased LOS (mean 12.4 vs 10.6 days, P = 0.015) and nonroutine discharge (OR 1.6, P < 0.001). In-hospital mortality did not differ (OR 2.4, P = 0.10).

CONCLUSION

Patients with OUD more frequently experienced complications and increased LOS. Close postoperative monitoring may mitigate adverse outcomes.

Disparities in Complications After Prolapse Repair and Sling Procedures: Trends From 2010-2018

OBJECTIVE

To compare 30-day complication rates after prolapse repair and sling procedures across racial/ethnic groups, and evaluate trends over time.

METHODS

We identified female patients in a national outcomes-based database who underwent prolapse repair and/or sling procedures between January 1, 2010 and December 31, 2018, stratified by race and ethnicity, and compared 30-day postoperative complication rates. Multivariable logistic regression adjusted for confounders. Trends in complication rates over time were evaluated using a test for trend (p-trend).

RESULTS

We identified 70,540 prolapse repairs and 23,968 sling procedures. Following prolapse repairs, Black women had the highest complication rates (11%, vs 8% for Hispanic and 9% for both White and Other race/ethnicity women, P <0.01). Following sling procedures, there were few differences in complication rates between groups. After adjustments, Black women still experienced higher odds of any complication (aOR 1.15, 95% CI 1.03-1.29), particularly a vascular complication (venous thromboembolism or transfusion) (aOR 2.50, 95% CI 2.05-3.04) following prolapse repair procedures. Hispanic women had higher odds of vascular complications after prolapse repair (aOR 1.47, 95% CI 1.23-1.76) and slings (aOR 2.40, 95% CI 1.53-3.76). Trends from 2010-2018 showed a decrease in vascular complication rates among non-Black women after prolapse repairs, but rates among Black women did not decrease.

CONCLUSION

Black women have higher odds of experiencing postoperative complications after prolapse repair procedures, particularly vascular complications. Vascular complication rates after prolapse repair decreased over time for all racial/ethnic groups except Black women. Hispanic women have higher odds of vascular complications after prolapse repair and slings than other racial/ethnic groups.

Impact of race on nonroutine discharge, length of stay, and postoperative complications after surgery for spinal metastases

OBJECTIVE

Previous studies have suggested the possibility of racial disparities in surgical outcomes for patients undergoing spine surgery, although this has not been thoroughly investigated in those with spinal metastases. Given the increasing prevalence of spinal metastases requiring intervention, knowledge about potential discrepancies in outcomes would benefit overall patient care. The objective in the present study was to investigate whether race was an independent predictor of postoperative complications, nonroutine discharge, and prolonged length of stay (LOS) after surgery for spinal metastasis.

METHODS

The authors retrospectively examined patients at a single comprehensive cancer center who had undergone surgery for spinal metastasis between April 2013 and April 2020. Demographic information, primary pathology, preoperative clinical characteristics, and operative outcomes were collected. Factors achieving p values < 0.15 on univariate regression were entered into a stepwise multivariable logistic regression to generate predictive models. Nonroutine discharge was defined as a nonhome discharge destination and prolonged LOS was defined as LOS greater than the 75th percentile for the entire cohort.

RESULTS

Three hundred twenty-eight patients who had undergone 348 operations were included: 240 (69.0%) White and 108 (31.0%) Black. On univariable analysis, cohorts significantly differed in age (p = 0.02), marital status (p < 0.001), insurance status (p = 0.03), income quartile (p = 0.02), primary tumor type (p = 0.04), and preoperative Karnofsky Performance Scale (KPS) score (p < 0.001). On multivariable analysis, race was an independent predictor for nonroutine discharge: Black patients had significantly higher odds of nonroutine discharge than White patients (adjusted odds ratio [AOR] 2.24, 95% confidence interval [CI] 1.28-3.92, p = 0.005). Older age (AOR 1.06 per year, 95% CI 1.03-1.09, p < 0.001), preoperative KPS score ≤ 70 (AOR 3.30, 95% CI 1.93-5.65, p < 0.001), preoperative Frankel grade A-C (AOR 3.48, 95% CI 1.17-10.3, p = 0.02), insurance status (p = 0.005), being unmarried (AOR 0.58, 95% CI 0.35-0.97, p = 0.04), number of levels (AOR 1.17 per level, 95% CI 1.05-1.31, p = 0.004), and thoracic involvement (AOR 1.71, 95% CI 1.02-2.88, p = 0.04) were also predictive of nonroutine discharge. However, race was not independently predictive of postoperative complications or prolonged LOS. Higher Charlson Comorbidity Index (AOR 1.22 per point, 95% CI 1.04-1.43, p = 0.01), low preoperative KPS score (AOR 1.84, 95% CI 1.16-2.92, p = 0.01), and number of levels (AOR 1.15 per level, 95% CI 1.05-1.27, p = 0.004) were predictive of complications, while insurance status (p = 0.05), income quartile (p = 0.01), low preoperative KPS score (AOR 1.64, 95% CI 1.03-2.72, p = 0.05), and number of levels (AOR 1.16 per level, 95% CI 1.05-1.30, p = 0.004) were predictive of prolonged LOS.

CONCLUSIONS

Race, insurance status, age, baseline functional status, and marital status were all independently associated with nonroutine discharge. This suggests that a combination of socioeconomic factors and functional status, rather than medical comorbidities, may best predict postdischarge disposition in patients treated for spinal metastases. Further investigation in a prospective cohort is merited.

The impact of hospital volume on racial disparities in resected rectal cancer

BACKGROUND

Although high volume centers (HVC) equate to improved outcomes in rectal cancer, the impact of surgical volume related to race is less defined.

METHODS

Patients who underwent surgical resection for stage I-III rectal adenocarcinoma were divided into cohorts based on race and hospital surgical volume. Outcomes were analyzed following 1:1 propensity-score matching using logistic, Poisson, and Cox regression analyses with marginal effects.

RESULTS

Fifty-four thousand one hundred and eighty-four (91.5%) non-Black and 5043 (8.5%) Black patients underwent resection of rectal cancer. Following 1:1 matching of non-Black (N = 5026) and Black patients, 5-year overall survival (OS) of Black patients was worse (72% vs. 74.4%, average marginal effects [AME] 0.66, p = 0.04) than non-Black patients. When compared to non-Black patients managed at HVCs, Black patients had worse OS (70.1% vs. 74.7%, AME 1.55, p = 0.03), but this difference was not significant when comparing OS between non-Black and Black patients managed at HVCs (72.3% vs. 74.7%, AME 0.62, p = 0.06). Length of stay was longer among Black and HVC patients across all cohorts. There was no difference across cohorts in 90-day mortality.

CONCLUSIONS

Although racial disparities exist in rectal cancer, this disparity appears to be ameliorated when patients are managed at HVCs.

Racial Disparities in Outcomes After Spine Surgery: A Systematic Review and Meta-Analysis

OBJECTIVE

Racial disparities are a major issue in health care but the overall extent of the issue in spinal surgery outcomes is unclear. We conducted a systematic review/meta-analysis of disparities in outcomes among patients belonging to different racial groups who had undergone surgery for degenerative spine disease.

METHODS

We searched Ovid MEDLINE, Scopus, Cochrane Review Database, and ClinicalTrials.gov from inception to January 20, 2021 for relevant articles assessing outcomes after spine surgery stratified by race. We included studies that compared outcomes after spine surgery for degenerative disease among different racial groups.

RESULTS

We found 30 studies that met our inclusion criteria (28 articles and 2 published abstracts). We included data from 20 cohort studies in our meta-analysis (3,501,830 patients), which were assessed to have a high risk of observation/selection bias. Black patients had a 55% higher risk of dying after spine surgery compared with white patients (relative risk [RR], 1.55, 95% confidence interval [CI], 1.28-1.87; I² = 70%). Similarly, black patients had a longer length of stay (mean difference, 0.93 days; 95% CI, 0.75-1.10; I² = 73%), and higher risk of nonhome discharge (RR, 1.63; 95% CI, 1.47-1.81; I² = 89%), and 30-day readmission (RR, 1.45; 95% CI, 1.03-2.04; I² = 96%). No significant difference was noted in the pooled analyses for complication or reoperation rates.

CONCLUSIONS

Black patients have a significantly higher risk of unfavorable outcomes after spine surgery compared with white patients. Further work in understanding the reasons for these disparities will help develop strategies to narrow the gap among the racial groups.

Measuring What Matters: Patient-Reported Outcome and Experience Measures for Men Undergoing Radical Prostatectomy

Patient-reported outcome and experience measures capture a reliable representation of a patient's functional outcomes and quality of life. However, they are only helpful if the data are easily comprehensible to patients and are accessible to providers, patients, and payers. If we want to ensure that these metrics are fair, accurate, and relevant, then physicians should be leaders in developing and adopting these tools.

Health Care Disparities and the Future of Pancreatic Cancer Care

There have been tremendous advances in the diagnosis and treatment of pancreatic cancer in the past decade, yet we are failing to achieve equitable outcomes for all patient populations. Disparities exist in the incidence, diagnosis, treatment, and outcomes of patients with pancreatic cancer. Inequities are based on racial and ethnic group, sex, socioeconomic status, and geography. To address disparities, future steps must focus on research methods, including collection and methodology, and policy measures, including access, patient tools, hospital incentives, and workforce diversity. Through these comprehensive efforts, we can begin to rectify inequitable care for treatment of patients with pancreatic cancer.

Patient Social Vulnerability and Hospital Community Racial/Ethnic Integration: Do All Patients Undergoing Pancreatectomy Receive the Same Care Across Hospitals?

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.

Racial Disparities in Bariatric Surgery Complications and Mortality Using the MBSAQIP Data Registry

Background

Racial disparities in postoperative complications have been demonstrated in bariatric surgery, yet the relationship of race to complication severity is unknown.

Study Design

Adult laparoscopic primary bariatric procedures were queried from the 2015 and 2016 MBSAQIP registry. Adjusted logistic and multinomial regressions were used to examine the relationships between race and 30-day complications categorized by the Clavien-Dindo grading system.

Results

A total of 212,970 patients were included in the regression analyses. For Black patients, readmissions were higher (OR = 1.39, p < 0.0001) and the odds of a Grade 1, 3, 4, or 5 complication were increased compared with White patients (OR = 1.21, p < 0.0001; OR = 1.21, p < 0.0001; OR = 1.22, p = 0.01; and OR = 1.43, p = 0.04) respectively. The odds of a Grade 3 complication for Hispanic patients were higher compared with White patients (OR = 1.59, p < 0.0001).

Conclusion

Black patients have higher odds of readmission and multiple grades of complications (including death) compared with White patients. Hispanic patients have higher odds of a Grade 3 complication compared with White patients. No significant differences were found with other races. Specific causes of these disparities are beyond the limitations of the dataset and stand as a topic for future inquiry.

Racial disparities in complications and costs after surgery for pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

The study objective was to examine the impact of race on inpatient complications and costs after inpatient surgery for pelvic organ prolapse (POP).

METHODS

In this retrospective cohort study, we identified women who underwent surgery for POP between 2012 and 2014. Patient demographics, outcomes, hospital characteristics, and hospital costs were extracted. Demographic and clinical characteristics were compared by race using Kruskal-Wallis for continuous variables and Chi-squared test for categorical variables. Multivariate logistic and linear regressions were used to identify variables associated with increased complications and costs respectively.

RESULTS

A total of 29,347 women with a median age of 62 years underwent inpatient surgery for POP between 2012 and 2014. There were 4,419 women (15%) who had at least one in-hospital postoperative complication. Rates of any postoperative complication were significantly higher among Black women (20%) than among white, Hispanic, and women of other races (16%, 11%, and 13% respectively, p < 0.01). The median total cost associated with surgeries for POP was $8,267 (IQR $6,008-$11,734). After multivariate analyses controlled for potential confounders, postoperative complications remained independently associated with Black race (aOR 1.21) whereas Hispanic and other races were associated with decreased odds of complications (aOR 0.62, and aOR 0.77) relative to white race. After controlling for confounders, Hispanic women had lower associated hospital costs.

CONCLUSIONS

Black women undergoing inpatient surgery for POP had a 21% increase in the odds of complications, but no difference in costs compared with white women, whereas Hispanic women had the lowest odds of complications and lowest costs.

Thirty-day complication rates do not differ by race among patients undergoing pancreaticoduodenectomy for pancreatic adenocarcinoma

BACKGROUND AND OBJECTIVES

Black patients with pancreatic ductal adenocarcinoma (PDAC) are less likely to receive multimodality treatment and have worse survival compared to White patients. However, little is known regarding racial differences in postoperative outcomes. The primary aim of this study was to determine if 30-day complication rates following pancreaticoduodenectomy (PD) differ by race.

METHODS

A retrospective cohort study of patients who underwent PD for PDAC from 2014 to 2016 within the ACS-NSQIP pancreatectomy-specific data set was performed. Primary outcomes were 30-day pancreas-specific and overall major complications.

RESULTS

A total of 6936 patients were identified, including 91.4% (N = 6337) White and 8.6% (N = 599) Black. Pathologic stage and rates of neoadjuvant therapy were similar among Whites and Blacks. Rates of pancreas-specific (23.9% vs. 23.1%, p = .88) and major postoperative complications (39.2% vs. 39.9%, p = .55) were similar between Whites and Blacks. By multivariable regression analysis, there was no association between race and odds of pancreas-specific complications (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.89-1.37) or overall major complications (OR 1.13, 95% CI 0.95-1.36).

CONCLUSIONS

Among patients undergoing PD for PDAC, Black race is not associated with increased pancreas-specific or overall 30-day postoperative complications. Short-term postoperative outcomes do not appear to explain the increase in pancreatic cancer mortality among Black patients.

High Social Vulnerability and "Textbook Outcomes" after Cancer Operation

BACKGROUND

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.

METHODS

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.

RESULTS

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, p < 0.05). 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, p < 0.05).

CONCLUSIONS

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.

Racial Differences in Gastroenteropancreatic Neuroendocrine Tumor Treatment and Survival in the United States

OBJECTIVES

The objective of this study was to evaluate racial differences in cancer treatment and survival in gastroenteropancreatic neuroendocrine tumor (GEP-NET) patients.

METHODS

Using the Surveillance, Epidemiology, and End Results Registry, we identified patients with GEP-NETs of the stomach, small intestine (SI), colon, rectum, appendix, and pancreas diagnosed between 1973 and 2014. Demographic, cancer, and treatment information were collected and compared using χ2 tests. Multivariable logistic and Cox regression were used to determine disparities in receiving treatment and overall survival.

RESULTS

We identified 19,031 GEP-NET patients: 2839 were non-Hispanic Blacks, 12,832 non-Hispanic Whites, 2098 Hispanics, and 1262 Asians. African Americans and Hispanics with SI and pancreatic NETs were less likely to be treated with surgery (odds ratio, 0.6; 95% confidence interval [CI], 0.46-0.69; odds ratio, 0.71; 95% CI, 0.51-0.99, respectively). African American race was not an independent predictor of survival; there was a strong trend in stomach, SI, and pancreas NETs (hazard ratio [HR], 1.31; 95% CI, 1-1.7; HR, 1.2; 95% CI, 0.99-1.45; HR, 1.22; 95% CI, 1-1.48, respectively).

CONCLUSIONS

Our study provides evidence of racial disparities in treatment and survival across GEP-NET primary sites and racial groups. Further studies should be performed to improve our understanding of the reason for these disparities.

Changes in Racial Disparities in Mortality After Cancer Surgery in the US, 2007-2016

IMPORTANCE

Racial disparities are well documented in cancer care. Overall, in the US, Black patients historically have higher rates of mortality after surgery than White patients. However, it is unknown whether racial disparities in mortality after cancer surgery have changed over time.

OBJECTIVE

To examine whether and how disparities in mortality after cancer surgery have changed over 10 years for Black and White patients overall and for 9 specific cancers.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study, national Medicare data were used to examine the 10-year (January 1, 2007, to November 30, 2016) changes in postoperative mortality rates in Black and White patients. Data analysis was performed from August 6 to December 31, 2019. Participants included fee-for-service beneficiaries enrolled in Medicare Part A who had a major surgical resection for 9 common types of cancer surgery: colorectal, bladder, esophageal, kidney, liver, ovarian, pancreatic, lung, or prostate cancer.

EXPOSURES

Cancer surgery among Black and White patients.

MAIN OUTCOMES AND MEASURES

Risk-adjusted 30-day, all-cause, postoperative mortality overall and for 9 specific types of cancer surgery.

RESULTS

A total of 870 929 cancer operations were performed during the 10-year study period. In the baseline year, a total of 103 446 patients had cancer operations (96 210 White patients and 7236 Black patients). Black patients were slightly younger (mean [SD] age, 73.0 [6.4] vs 74.5 [6.8] years), and there were fewer Black vs White men (3986 [55.1%] vs 55 527 [57.7%]). Overall national mortality rates following cancer surgery were lower for both Black (-0.12%; 95% CI, -0.17% to -0.06% per year) and White (-0.14%; 95% CI, -0.16% to -0.13% per year) patients. These reductions were predominantly attributable to within-hospital mortality improvements (Black patients: 0.10% annually; 95% CI, -0.15% to -0.05%; P < .001; White patients: 0.13%; 95% CI, -0.14% to -0.11%; P < .001) vs between-hospital mortality improvements. Across the 9 different cancer surgery procedures, there was no significant difference in mortality changes between Black and White patients during the period under study (eg, prostate cancer: 0.35; 95% CI, 0.02-0.68; lung cancer: 0.61; 95% CI, -0.21 to 1.44).

CONCLUSIONS AND RELEVANCE

These findings offer mixed news for policy makers regarding possible reductions in racial disparities following cancer surgery. Although postoperative cancer surgery mortality rates improved for both Black and White patients, there did not appear to be any narrowing of the mortality gap between Black and White patients overall or across individual cancer surgery procedures.

Postoperative mortality in New Zealand following general anaesthetic: demographic patterns and temporal trends

OBJECTIVES

In this manuscript, we describe broad trends in postoperative mortality in New Zealand (a country with universal healthcare) for acute and elective/waiting list procedures conducted between 2005 and 2017.

DESIGN, PARTICIPANTS AND SETTING

We use high-quality national-level hospitalisation data to compare the risk of postoperative mortality between demographic subgroups after adjusting for key patient-level confounders and mediators. We also present temporal trends and consider how rates in postoperative death following acute and elective/waiting list procedures have changed over this time period.

RESULTS AND CONCLUSION

A total of 1 836 683 unique patients accounted for 3 117 374 admissions in which a procedure was performed under general anaesthetic over the study period. We observed an overall 30-day mortality rate of 0.5 per 100 procedures and a 90-day mortality rate of 0.9 per 100. For acute procedures, we observed a 30-day mortality rate of 1.6 per 100, compared with 0.2 per 100 for elective/waiting list procedures. In terms of procedure specialty, respiratory and cardiovascular procedures had the highest rate of 30-day mortality (age-standardised rate, acute procedures: 3-6 per 100; elective/waiting list: 0.7-1 per 100). As in other contexts, we observed that the likelihood of postoperative death was not proportionally distributed within our population: older patients, Māori patients, those living in areas with higher deprivation and those with comorbidity were at increased risk of postoperative death, even after adjusting for all available factors that might explain differences between these groups. Increasing procedure risk (measured using the Johns Hopkins Surgical Risk Classification System) was also associated with an increased risk of postoperative death. Encouragingly, it appears that risk of postoperative mortality has declined over the past decade, possibly reflecting improvements in perioperative quality of care; however, this decline did not occur equally across procedure specialties.

Influence of Insurance Status and Demographic Factors on Outcomes Following Tracheostomy

OBJECTIVES/HYPOTHESIS

Little data exists regarding the relationship between socioeconomic and demographic factors and tracheostomy outcomes. The goal of this study was to determine associations between socioeconomic status (SES), demographic factors, and insurance status with hospital length of stay (LOS), intensive care unit (ICU) LOS, and mortality following tracheostomy.

STUDY DESIGN

Retrospective cohort study.

METHODS

A retrospective analysis of all patients who underwent tracheostomy at an urban tertiary-care academic hospital from 2016 to 2017 was performed. Patients were aggregated into low-, middle-, and high-income brackets. Other variables included age, sex, race, ethnicity, body mass index, and Charlson Comorbidity Index (CCI). Outcomes included hospital and ICU LOS, in-hospital mortality, and 30-day mortality following tracheostomy. Outcomes were compared using Kruskal-Wallis tests for continuous variables and χ² or Fisher exact tests for categorical variables. The α level was set to .05.

RESULTS

In total, 523 patients were included in the study. Patients from high-income areas were more likely to be male (P < .01), white (P < .01), and had lower body mass index (P = .04). On multiple regression analysis, Hispanic or Latino ethnicity was associated with an increased odds of 30-day mortality (odds ratio [OR]: 4.43, P = .020). CCI was also associated with increased odds of 30-day mortality (OR: 1.12, P = .039).

CONCLUSIONS

Lower SES was not associated with increased morbidity or mortality after tracheostomy. Although Hispanic patients tended to have a lower CCI score, they had increased 30-day mortality, suggesting there are factors specific to this population that may influence outcomes, and future targeted studies are warranted to study these relationships.

Perioperative complications and oncological outcomes following radical cystectomy among different racial groups: A long-term, single-center study

INTRODUCTION

Current literature on perioperative and oncological outcomes following radical cystectomy among different racial groups is limited, especially among Hispanics and Asians. The objective of this study was to assess the impact of racial differences on perioperative and oncological outcomes in a large cohort of bladder cancer patients who underwent radical cystectomy.

METHODS

We retrospectively reviewed the records of 3293 patients who underwent radical cystectomy with curative intent at our institution between 1971 and 2017. Based on race, patients were categorized as Hispanic (n=190), Asian (n=145), African American (n=67), and Caucasian (n=2891). Baseline characteristics, pericystectomy complications, and oncological outcomes, including recurrence-free and overall survival, were compared between the racial groups.

RESULTS

Mean patient age was 68±10.6 years. Median followup was 10.28 years. Body masss index and American Society of Anesthesiologists scores were significantly higher in Hispanic and African American population, and smoking incidence was lower in Asian patients. Hispanics presented with significantly higher clinical stage and longer time interval from diagnosis to treatment (mean 85.5 vs. 75.4 days in Caucasians, p<0.001). Overall 90-day complication and readmission rates were higher in Hispanics (41.06% and 18.95%, respectively). Oncological outcomes, however, were comparable between different race groups. In multivariate analysis, pathological nodal status and lymphovascular invasion were independent predictors of oncological outcomes, but race was not.

CONCLUSIONS

In this very large, ethnically diverse patient cohort who underwent radical cystectomy with curative intent, pericystectomy complications were more common in Hispanics; however, race was not an independent predictor of long-term oncological outcome.

Disparities in Bladder Cancer Outcomes Based on Key Sociodemographic Characteristics

PURPOSE OF REVIEW

A review of the impact of several key patient characteristics on oncologic outcomes in bladder cancer (BC) summarized and analyzed in a narrative fashion.

RECENT FINDINGS

The bulk of the published literature suggests that females and blacks have poorer cancer-specific outcomes. Both groups tend to present with worse disease, which may be driven by differences in access to timely and quality care. Attempts to assess the association between smoking status and history and BC outcomes have been hindered by the quality and heterogeneity of the data, although several studies have linked smoking with higher rates of recurrence and poorer survival. Being married, particularly in men, may improve survival after radical cystectomy (RC). Limited data suggests that socioeconomic and education levels may be associated with poorer survival; however, the data is limited. A growing body of investigation suggests that there are significant differences in oncologic outcomes in BC patients based on race, gender, smoking status, socioeconomic status, and others. Further focus and investigation is needed to validate these findings, investigate the root cause of these differences, and offer solutions to mitigate them.
