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

Colorectal cancer care continuum: Navigating screening, treatment, and outcomes disparities

This review investigates the disparities in colorectal cancer screening, treatment, and outcomes among different racial, ethnic, socioeconomic, and geographic groups. Although there has been progress, notable disparities continue to exist as a result of socioeconomic status, access to healthcare, and systemic prejudices. Approaches to tackle these challenges involve expanding screening access, enhancing healthcare utilization, addressing socioeconomic obstacles, ensuring fair treatment, and boosting representation in research.

Race norming and biases in surgical oncology care

Disparities in surgical oncology care may be due to race/ethnicity. Race norming, defined as the adjustment of medical assessments based on an individual's race/ethnicity, and implicit bias are specifically explored in this focused systematic review. We aim to examine how race norming and bias impact oncologic care and postsurgical outcomes, particularly in Black patient populations, while providing potential strategies to improve equitable and inclusive care.

Adapting Enhanced Recovery After Surgery (ERAS) Protocols to Promote Equity in Cancer Care and Outcomes

MINI ABSTRACT

Equity-focused evaluations of existing healthcare system-level policies, clinical practices, and interventions are needed to identify factors that may narrow, or unintentionally widen, the racial disparity in cancer outcomes. We focus here on the evaluation of enhanced recovery after surgery (ERAS) protocols and their potential to promote equity in cancer care and outcomes.

Differences in outcomes by race/ethnicity after thoracic surgery in a large integrated health system

Background

Disparities exist throughout surgery. We aimed to assess for racial/ethnic disparities among outcomes in a large thoracic surgery patient population.

Methods

We reviewed all thoracic surgery patients treated at our integrated health system from January 1, 2016-December 31, 2020. Post-operative outcomes including length of stay (LOS), 30-day return to the emergency department (30d-ED), 30-day readmission, 30- and 90-day outpatient appointments, and 30- and 90-day mortality were compared by race/ethnicity. Bivariate analyses and multivariable logistic regression were performed. Our multivariable models adjusted for age, sex, body mass index, Charlson Comorbidity Index, surgery type, neighborhood deprivation index, insurance, and home region.

Results

Of 2730 included patients, 59.4 % were non-Hispanic White, 15.0 % were Asian, 11.9 % were Hispanic, 9.6 % were Black, and 4.1 % were Other. Median (Q1-Q3) LOS (in hours) was shortest among non-Hispanic White (37.3 (29.2-76.1)) and Other (36.5 (29.3-75.4)) patients followed by Hispanic (46.8 (29.9-78.1)) patients with Asian (51.3 (30.7-81.9)) and Black (53.7 (30.6-101.6)) patients experiencing the longest LOS (p < 0.01). 30d-ED rates were highest among Hispanic patients (21.3 %), followed by Black (19.2 %), non-Hispanic White (18.1 %), Asian (13.4 %), and Other (8.0 %) patients (p < 0.01). On multivariable analysis, Hispanic ethnicity (Odds Ratio (OR) 1.43 (95 % CI 1.03-1.97)) and Medicaid insurance (OR 2.37 (95 % CI 1.48-3.81)) were associated with higher 30d-ED rates. No racial/ethnic disparities were found among other outcomes.

Conclusions

Despite parity across multiple surgical outcomes, disparities remain related to patient encounters within our system. Health systems must track such disparities in addition to standard clinical outcomes.

Key message

While our large integrated health system has been able to demonstrate parity across many major surgical outcomes among our thoracic surgery patients, race/ethnicity disparities persist including in the number of post-operative return trips to the emergency department. Tracking outcome disparities to a granular level such as return visits to the emergency department and number of follow up appointments is critical as health systems strive to achieve equitable care.

Disparities in Cancer Stage Outcomes by Catchment Areas for a Comprehensive Cancer Center

Importance

The National Cancer Institute comprehensive cancer centers (CCCs) lack spatial and temporal evaluation of their self-designated catchment areas.

Objective

To identify disparities in cancer stage at diagnosis within and outside a CCC's catchment area across a 10-year period using spatial and statistical analyses.

Design, Setting, and Participants

This cross-sectional, population-based study conducted between 2010 and 2019 utilized cancer registry data for the Johns Hopkins Sidney Kimmel CCC (SKCCC). Eligible participants included patients with cancer in the contiguous US who received treatment for cancer, a diagnosis of cancer, or both at SKCCC. Patients were geocoded to zip code tabulation areas (ZCTAs). Individual-level variables included sociodemographic characteristics, smoking and alcohol use, treatment type, cancer site, and insurance type. Data analysis was performed between March and July 2023.

Exposures

Distance between SKCCC and ZCTAs were computed to generate a catchment area of the closest 75% of patients and outer zones in 5% increments for comparison.

Main Outcomes and Measures

The primary outcome was cancer stage at diagnosis, defined as early-stage, late-stage, or unknown stage. Multinomial logistic regression was used to determine associations of catchment area with stage at diagnosis.

Results

This study had a total of 94 007 participants (46 009 male [48.94%] and 47 998 female [51.06%]; 30 195 aged 22-45 years [32.12%]; 4209 Asian [4.48%]; 2408 Hispanic [2.56%]; 16 004 non-Hispanic Black [17.02%]; 69 052 non-Hispanic White [73.45%]; and 2334 with other or unknown race or ethnicity [2.48%]), including 47 245 patients (50.26%) who received a diagnosis of early-stage cancer, 19 491 (20.73%) who received a diagnosis of late-stage cancer , and 27 271 (29.01%) with unknown stage. Living outside the main catchment area was associated with higher odds of late-stage cancers for those who received only a diagnosis (odds ratio [OR], 1.50; 95% CI, 1.10-2.05) or only treatment (OR, 1.44; 95% CI, 1.28-1.61) at SKCCC. Non-Hispanic Black patients (OR, 1.16; 95% CI, 1.10-1.23) and those with Medicaid (OR, 1.65; 95% CI, 1.46-1.86) and no insurance at time of treatment (OR, 2.12; 95% CI, 1.79-2.51) also had higher odds of receiving a late-stage cancer diagnosis.

Conclusions and Relevance

In this cross-sectional study of CCC data from 2010 to 2019, patients residing outside the main catchment area, non-Hispanic Black patients, and patients with Medicaid or no insurance had higher odds of late-stage diagnoses. These findings suggest that disadvantaged populations and those living outside of the main catchment area of a CCC may face barriers to screening and treatment. Care-sharing agreements among CCCs could address these issues.

Leveraging Ethnic Backgrounds to Improve Collection of Race, Ethnicity, and Language Data

INTRODUCTION

Healthcare disparities may be exacerbated by upstream incapacity to collect high-quality and accurate race, ethnicity, and language (REaL) data. There are opportunities to remedy these data barriers. We present the Denver Health (DH) REaL initiative, which was implemented in 2021.

METHODS

Denver Health is a large safety net health system. After assessing the state of REaL data at DH, we developed a standard script, implemented training, and adapted our electronic health record to collect this information starting with an individual's ethnic background followed by questions on race, ethnicity, and preferred language. We analyzed the data for completeness after REaL implementation.

RESULTS

A total of 207,490 patients who had at least one in-person registration encounter before and after the DH REaL implementation were included in our analysis. There was a significant decline in missing values for race (7.9%-0.5%, p < .001) and for ethnicity (7.6%-0.3%, p < .001) after implementation. Completely of language data also improved (3%-1.6%, p < .001). A year after our implementation, we knew over 99% of our cohort's self-identified race and ethnicity.

CONCLUSIONS

Our initiative significantly reduced missing data by successfully leveraging ethnic background as the starting point of our REaL data collection.

Association of County-Level Food Deserts and Food Swamps with Hepatopancreatobiliary Cancer Outcomes

BACKGROUND

Malnutrition has been linked to the development of hepatopancreatobiliary (HPB) cancer. We sought to examine the association between food swamps and food deserts on surgical outcomes of patients with HPB cancer.

METHODS

Patients who underwent surgery for HPB cancer between 2014 and 2020 were identified from the Medicare Standard Analytic Files. Patient-level data were linked to the United States Department of Agriculture data on food swamps and deserts. Multivariable regression was performed to examine the association between the food environment and outcomes.

RESULTS

Among 53,426 patients, patients from the worse food environment were more likely to be Black, have a higher Charlson Comorbidity Index, and reside in areas with high social vulnerability. Following surgery, the overall incidence of textbook outcome (TO) was 41.6% (n = 22,220). Patients residing in the worse food environments less often achieved a TO versus individuals residing in the healthiest food environments (food swamp: 39.4% vs. 43.9%; food desert: 38.5% vs 42.2%; p < 0.05). On multivariable analysis, individuals residing in the poorest food environments were associated with lower odds of achieving TO compared with individuals living in healthiest food environments (food swamp: OR 0.83, 95%CI 0.75-0.92, food desert: OR 0.86, 95%CI 0.76-0.97; both p < 0.05).

CONCLUSION

The surrounding food environment of patients may serve as a modifiable socio-demographic risk factor that contributes to disparities in surgical outcomes of HPB cancer.

Current Trends in Mortality Attributable to Racial or Ethnic Disparities in Post-Surgical Population in The United States: A Population-Based Study

Background

No study has contextualized the excess mortality attributable to racial and ethnic disparities in surgical outcomes. Further, not much effort has been made to quantify the effort needed to eliminate these disparities.

Objective

We examined the current trends in mortality attributable to racial or ethnic disparities in the US postsurgical population. We then identified the target for mortality reduction that would be necessary to eliminate these disparities by 2030.

Methods

We performed a population-based study of 1,512,974 high-risk surgical procedures among adults (18-64 years) performed across US hospitals between 2000 and 2020.

Results

Between 2000 and 2020, the risk-adjusted mortality rates declined for all groups. Nonetheless, Black patients were more likely to die following surgery (adjusted relative risk 1.42; 95% CI, 1.39-1.46) driven by higher Black mortality in the northeast (1.60; 95% CI, 1.52-1.68), as well as the West (1.53; 95% CI, 1.43-1.62). Similarly, mortality risk remained consistently higher for Hispanics compared with White patients (1.21; 95% CI, 1.19-1.24), driven by higher mortality in the West (1.26; 95% CI, 1.21-1.31). Overall, 8364 fewer deaths are required for Black patients to experience mortality on the same scale as White patients. Similar figures for Hispanic patients are 4388. To eliminate the disparity between Black and White patients by 2030, we need a 2.7% annualized reduction in the projected mortality among Black patients. For Hispanics, the annualized reduction needed is 0.8%.

Conclusions

Our data provides a framework for incorporating population and health systems measures for eliminating disparity in surgical mortality within the next decade.

The Other Pandemic, Racism, in Urology

Racism is deeply ingrained in our society with lasting effects within medicine. The COVID-19 pandemic further highlighted racial disparities in the medical field, including in the field of Urology. This has led to investigation regarding the effects of racism on education, patient care, and research within Urology. This article aims to review current literature on the "other pandemic," structural racism, within medicine and specifically urology and provide ways to combat its impact.

Neighborhood-Level Socioeconomic Disadvantage Predicts Outcomes in Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Peritoneal Malignancy

BACKGROUND

Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) improves survival in select patients with peritoneal metastases (PM), but the impact of social determinants of health on CRS/HIPEC outcomes remains unclear.

PATIENTS AND METHODS

A retrospective review was conducted of a multi-institutional database of patients with PM who underwent CRS/HIPEC in the USA between 2000 and 2017. The area deprivation index (ADI) was linked to the patient's residential address. Patients were categorized as living in low (1-49) or high (50-100) ADI residences, with increasing scores indicating higher socioeconomic disadvantage. The primary outcome was overall survival (OS). Secondary outcomes included perioperative complications, hospital/intensive care unit (ICU) length of stay (LOS), and disease-free survival (DFS).

RESULTS

Among 1675 patients 1061 (63.3%) resided in low ADI areas and 614 (36.7%) high ADI areas. Appendiceal tumors (n = 1102, 65.8%) and colon cancer (n = 322, 19.2%) were the most common histologies. On multivariate analysis, high ADI was not associated with increased perioperative complications, hospital/ICU LOS, or DFS. High ADI was associated with worse OS (median not reached versus 49 months; 5 year OS 61.0% versus 28.2%, P < 0.0001). On multivariate Cox-regression analysis, high ADI (HR, 2.26; 95% CI 1.13-4.50; P < 0.001), cancer recurrence (HR, 2.26; 95% CI 1.61-3.20; P < 0.0001), increases in peritoneal carcinomatosis index (HR, 1.03; 95% CI 1.01-1.05; P < 0.001), and incomplete cytoreduction (HR, 4.48; 95% CI 3.01-6.53; P < 0.0001) were associated with worse OS.

CONCLUSIONS

Even after controlling for cancer-specific variables, adverse outcomes persisted in association with neighborhood-level socioeconomic disadvantage. The individual and structural-level factors leading to these cancer disparities warrant further investigation to improve outcomes for all patients with peritoneal malignancies.

Social determinants of health and lung cancer surgery: a qualitative study

Introduction

Social determinants of health (SDOH) are non-clinical factors that may affect the outcomes of cancer patients. The purpose of this study was to describe the influence of SDOH factors on quality of life (QOL)-related outcomes for lung cancer surgery patients.

Methods

Thirteen patients enrolled in a randomized trial of a dyadic self-management intervention were invited and agreed to participate in semi-structured key informant interviews at study completion (3 months post-discharge). A conventional content analysis approach was used to identify codes and themes that were derived from the interviews. Independent investigators coded the qualitative data, which were subsequently confirmed by a second group of independent investigators. Themes were finalized, and discrepancies were reviewed and resolved.

Results

Six themes, each with several subthemes, emerged. Overall, most participants were knowledgeable about the concept of SDOH and perceived that provider awareness of SDOH information was important for the delivery of comprehensive care in surgery. Some participants described financial challenges during treatment that were exacerbated by their cancer diagnosis and resulted in stress and poor QOL. The perceived impact of education varied and included its importance in navigating the healthcare system, decision-making on health behaviors, and more economic mobility opportunities. Some participants experienced barriers to accessing healthcare due to insurance coverage, travel burden, and the fear of losing quality insurance coverage due to retirement. Neighborhood and built environment factors such as safety, air quality, access to green space, and other environmental factors were perceived as important to QOL. Social support through families/friends and spiritual/religious communities was perceived as important to postoperative recovery.

Discussion

Among lung cancer surgery patients, SDOH factors can impact QOL and the patient's survivorship journey. Importantly, SDOH should be assessed routinely to identify patients with unmet needs across the five domains. SDOH-driven interventions are needed to address these unmet needs and to improve the QOL and quality of care for lung cancer surgery patients.

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.

Something's got to give: How do we improve care for minorities, dual-eligible medicare, and disadvantaged patients?

This study highlights the implications of surgical disparities on health care spending. The strengths of this study include pinning down the potential etiologies of how surgical disparities contribute to excessive spending. Prior studies have focused primarily on individual social factors, yet this study takes into consideration the financial implications of disparities from multiple levels.6 Black patients face more challenges in cancer care in part due to late stage presentation and diagnosis, as well as increased exposure to risk factors that place them under a disproportionate burden of disease and risk of post-operative complications.7 We commend the authors for broaching this rarely discussed and costly combination of minority race and dual eligibility contributing to a "multiple hit" phenomenon that our most vulnerable patients face.

Association between the Environmental Quality Index and Textbook Outcomes Among Medicare Beneficiaries Undergoing Surgery for Early-Stage Pancreatic Adenocarcinoma

BACKGROUND

Access to high-quality cancer care is affected by environmental exposures and structural inequities. This study sought to investigate the association between the environmental quality index (EQI) and achievement of textbook outcomes (TO) among Medicare beneficiaries over the age of 65 who underwent surgical resection for early-stage pancreatic adenocarcinoma (PDAC).

METHODS

Patients diagnosed with early-stage PDAC from 2004 to 2015 were identified using the SEER-Medicare database and combined with the US Environmental Protection Agency's EQI data. High EQI category indicated poor environmental quality, whereas low EQI indicated better environmental conditions.

RESULTS

A total of 5,310 patients were included, of which 45.0% (n = 2,387) patients achieved TO. Median age was 73 years and more than half were female (n = 2,807, 52.9%), married (n = 3,280, 61.8%), and resided in the Western region of the US (n = 2,712, 51.1%). On multivariable analysis, patients residing in moderate and high EQI counties were less likely to achieve a TO (referent: low EQI; moderate EQI: OR 0.66, 95% CI 0.46-0.95; high EQI: OR 0.65, 95% CI 0.45-0.94; p < 0.05). Increasing age (OR 0.98, 95%CI 0.97-0.99), racial minorities (OR 0.73, 95% CI 0.63-0.85), having a Charlson co-morbidity index > 2 (OR 0.54, 95%CI 0.47-0.61) and stage II disease (OR 0.82, 95%CI 0.71-0.96) were also associated with not achieving a TO (all p < 0.001).

CONCLUSION

Older Medicare patients residing in moderate or high EQI counties were less likely to achieve an "optimal" TO after surgery. These results demonstrate that environmental factors may drive post-operative outcomes among patients with PDAC.

Conditional Effects of Race on Operative and Nonoperative Outcomes of Emergency General Surgery Conditions

INTRODUCTION

Many emergency general surgery (EGS) conditions can be managed both operatively or nonoperatively; however, it is unknown whether the decision to operate affects Black and White patients differentially.

METHODS

We identified a nationwide cohort of Black and White Medicare beneficiaries, hospitalized for common EGS conditions from July 2015 to June 2018. Using near-far matching to adjust for measurable confounding and an instrumental variable analysis to control for selection bias associated with treatment assignment, we compare outcomes of operative and nonoperative management in a stratified population of Black and White patients. Outcomes included in-hospital mortality, 30-day mortality, nonroutine discharge, and 30-day readmissions. An interaction test based on a t test was used to determine the conditional effects of operative versus nonoperative management between Black and White patients.

RESULTS

A total of 556,087 patients met inclusion criteria, of which 59,519 (10.7%) were Black and 496,568 (89.3%) were White. Overall, 165,932 (29.8%) patients had an operation and 390,155 (70.2%) were managed nonoperatively. Significant outcome differences were seen between operative and nonoperative management for some conditions; however, no significant differences were seen for the conditional effect of race on outcomes.

CONCLUSIONS

The decision to manage an EGS patient operatively versus nonoperatively has varying effects on surgical outcomes. These effects vary by EGS condition. There were no significant conditional effects of race on the outcomes of operative versus nonoperative management among universally insured older adults hospitalized with EGS conditions.

Surgical Care for Racial and Ethnic Minorities and Interventions to Address Inequities: A Narrative Review

OBJECTIVE

Racial and ethnic inequities in surgical care in the United States are well documented. Less is understood about evidence-based interventions that improve surgical care and reduce or eliminate inequities. In this review, we discuss effective patient, surgeon, community, health care system, policy, and multi-level interventions to reduce inequities and identifying gaps in intervention-based research.

BACKGROUND

Evidenced-based interventions to reduce racial and ethnic inequities in surgical care are key to achieving surgical equity. Surgeons, surgical trainees, researchers, and policy makers should be aware of the evidence-based interventions known to reduce racial and ethnic disparities in surgical care for prioritization of resource allocation and implementation. Future research is needed to assess interventions effectiveness in the reduction of disparities and patient-reported measures.

METHODS

We searched PubMed database for English-language studies published from January 2012 through June 2022 to assess interventions to reduce or eliminate racial and ethnic disparities in surgical care. A narrative review of existing literature was performed identifying interventions that have been associated with reduction in racial and ethnic disparities in surgical care.

RESULTS AND CONCLUSIONS

Achieving surgical equity will require implementing evidenced-based interventions to improve quality for racial and ethnic minorities. Moving beyond description toward elimination of racial and ethnic inequities in surgical care will require prioritizing funding of intervention-based research, utilization of implementation science and community based-participatory research methodology, and principles of learning health systems.

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.

Addressing racial and ethnic disparities in US liver cancer care

HCC, the most common form of primary liver cancer, is the fastest rising cause of cancer-related death in the United States. HCC disproportionately affects racial and ethnic minorities in the United States. A practical framework is needed to organize the complex patient, provider, health system, and societal factors that drive these racial and ethnic disparities. In this narrative review, we adapted and applied the National Institute on Minority Health and Health Disparities (NIMHD) Research Framework to the HCC care continuum, as a step toward better understanding and addressing existing HCC-related disparities. We first summarize the literature on HCC-related disparities by race and ethnicity organized by the framework's 5 domains (biological, behavioral, physical/built environment, sociocultural environment, and health care system) and 4 levels (individual, interpersonal, community, and societal) of influence. We then offer strategies to guide future research initiatives toward promotion of health equity in HCC care. Clinicians and researchers may help mitigate further inequities and better address racial and ethnic disparities in HCC care by prioritizing the following in HCC research: (1) increasing racial and ethnic minority representation, (2) collecting and reporting HCC-related data by racial and ethnic subgroups, (3) assessing the patient experience of HCC care by race and ethnicity, and (4) evaluating HCC-specific social determinants of health by race and ethnicity. These 4 priorities will help inform the development of future programs and interventions that are tailored to the unique experiences of each racial and ethnic group.

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.

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.

Racial Disparities in Surgical Outcomes of Acute Diverticulitis: Have We Moved the Needle?

INTRODUCTION

There has been increasing national attention on reducing healthcare disparities. Prior studies cite worse surgical outcomes and less use of laparoscopy for Black patients with diverticulitis. Re-evaluation of these disparities is lacking despite national initiatives to improve health equity. This study aimed to evaluate the association of race with short-term outcomes and surgical approaches in patients with acute diverticulitis.

METHODS

The National Surgical Quality Improvement Program database was queried for patients who underwent nonelective surgery for acute diverticulitis from 2015 to 2019. Severity of presentation, morbidity, mortality, surgical approach, and ostomy creation were compared by race.

RESULTS

Of the 13,996 patients included in the study, 82.4% were White, 7.6% were Black, 1.1% Asian, 0.61% American Indian/Alaska Native, and 0.20% Native Hawaiian/Pacific Islander (NH/PI). Overall 30-day morbidity was 44.3% and 30-day mortality was 3.9%. In a multivariate logistic regression analysis, compared to Whites, Black race was independently associated with higher 30-day morbidity (Odds Ratio: 1.24, 95% confidence interval: 1.07-1.43, P = 0.003) and NH/PI race was independently associated with higher mortality (Odds Ratio: 5.35, 95% confidence interval: 1.32-21.6, P = 0.019). There was no difference in complicated disease (abscess or perforation), use of laparoscopy, or ostomy creation among races.

CONCLUSIONS

Despite national efforts to achieve equity in healthcare, disparities persist in surgical outcomes for those with diverticulitis. Black and NH/PI race are independently associated with increased morbidity and mortality, respectively. Use of laparoscopy, however, is no longer different by race suggesting some gaps may be closing.

Inequities in surgical outcomes by race and sex in the United States: retrospective cohort study

OBJECTIVE

To assess inequities in mortality by race and sex for eight common surgical procedures (elective and non-elective) across specialties in the United States.

DESIGN

Retrospective cohort study.

SETTING

US, 2016-18.

PARTICIPANTS

1 868 036 Black and White Medicare beneficiaries aged 65-99 years undergoing one of eight common surgeries: repair of abdominal aortic aneurysm, appendectomy, cholecystectomy, colectomy, coronary artery bypass surgery, hip replacement, knee replacement, and lung resection.

MAIN OUTCOME MEASURE

The main outcome measure was 30 day mortality, defined as death during hospital admission or within 30 days of the surgical procedure.

RESULTS

Postoperative mortality overall was higher in Black men (1698 deaths, adjusted mortality rate 3.05%, 95% confidence interval 2.85% to 3.24%) compared with White men (21 833 deaths, 2.69%, 2.65% to 2.73%), White women (21 847 deaths, 2.38%, 2.35% to 2.41%), and Black women (1631 deaths, 2.18%, 2.04% to 2.31%), after adjusting for potential confounders. A similar pattern was found for elective surgeries, with Black men showing a higher adjusted mortality (393 deaths, 1.30%, 1.14% to 1.46%) compared with White men (5650 deaths, 0.85%, 0.83% to 0.88%), White women (4615 deaths, 0.82%, 0.80% to 0.84%), and Black women (359 deaths, 0.79%, 0.70% to 0.88%). This 0.45 percentage point difference implies that mortality after elective procedures was 50% higher in Black men compared with White men. For non-elective surgeries, however, mortality did not differ between Black men and White men (1305 deaths, 6.69%, 6.26% to 7.11%; and 16 183 deaths, 7.03%, 6.92% to 7.14%, respectively), although mortality was lower for White women and Black women (17 232 deaths, 6.12%, 6.02% to 6.21%; and 1272 deaths, 5.29%, 4.93% to 5.64%, respectively). These differences in mortality appeared within seven days after surgery and persisted for up to 60 days after surgery.

CONCLUSIONS

Postoperative mortality overall was higher among Black men compared with White men, White women, and Black women. These findings highlight the need to understand better the unique challenges Black men who require surgery face.

Rural Disparities in Lung Cancer-directed Surgery: A Medicare Cohort Study

OBJECTIVE

The primary objective of this study was to determine the influence of rural residence on access to and outcomes of lung cancer-directed surgery for Medicare beneficiaries.

SUMMARY OF BACKGROUND DATA

Lung cancer is the leading cause of cancerrelated death in the United States and rural patients have 20% higher mortality. Drivers of rural disparities along the continuum of lung cancercare delivery are poorly understood.

METHODS

Medicare claims (2015-2018) were used to identify 126,352 older adults with an incident diagnosis of nonmetastatic lung cancer. Rural Urban Commuting Area codes were used to define metropolitan, micropolitan, small town, and rural site of residence. Multivariable logistic regression models evaluated influence of place of residence on 1) receipt of cancer-directed surgery, 2) time from diagnosis to surgery, and 3) postoperative outcomes.

RESULTS

Metropolitan beneficiaries had higher rate of cancer-directed surgery (22.1%) than micropolitan (18.7%), small town (17.5%), and isolated rural (17.8%) (P < 0.001). Compared to patients from metropolitan areas, there were longer times from diagnosis to surgery for patients living in micropolitan, small, and rural communities. Multivariable models found nonmetropolitan residence to be associated with lower odds of receiving cancer-directed surgery and MIS. Nonmetropolitan residence was associated with higher odds of having postoperative emergency department visits.

CONCLUSIONS

Residence in nonmetropolitan areas is associated with lower probability of cancer-directed surgery, increased time to surgery, decreased use of MIS, and increased postoperative ED visits. Attention to timely access to surgery and coordination of postoperative care for nonmetropolitan patients could improve care delivery.

Differential pulse oximetry readings between ethnic groups and delayed transfer to intensive care units

BACKGROUND

Pulse oximeters are widely used to monitor blood oxygen saturations, although concerns exist that they are less accurate in individuals with pigmented skin.

AIMS

This study aimed to determine if patients with pigmented skin were more severely unwell at the period of transfer to intensive care units (ICUs) than individuals with White skin.

METHODS

Using data from a large teaching hospital, measures of clinical severity at the time of transfer of patients with COVID-19 infection to ICUs were assessed, and how this varied by ethnic group.

RESULTS

Data were available on 748 adults. Median pulse oximetry demonstrated similar oxygen saturations at the time of transfer to ICUs (Kruskal-Wallis test, P = 0.51), although median oxygen saturation measurements from arterial blood gases at this time demonstrated lower oxygen saturations in patients classified as Indian/Pakistani ethnicity (91.6%) and Black/Mixed ethnicity (93.0%), compared to those classified as a White ethnicity (94.4%, Kruskal-Wallis test, P = 0.005). There were significant differences in mean respiratory rates in these patients (P < 0.0001), ranging from 26 breaths/min in individuals with White ethnicity to 30 breaths/min for those classified as Indian/Pakistani ethnicity and 31 for those who were classified as Black/Mixed ethnicity.

CONCLUSIONS

These data are consistent with the hypothesis that differential measurement error for pulse oximeter readings negatively impact on the escalation of clinical care in individuals from other than White ethnic groups. This has implications for healthcare in Africa and South-East Asia and may contribute to differences in health outcomes across ethnic groups globally.

Characteristics Contributing to Survival Differences Between Black and White Patients Following Cystectomy

PURPOSE

Examine patient, tumor, and treatment characteristics effect on the disparity between black and white patients with muscle-invasive bladder cancer (MIBC) who undergo radical cystectomy (RC).

METHODS

1,286 black patients in the 2004 to 2016 National Cancer Database fit inclusion criteria. A tapered match was performed from 17,374 white patients sequentially matched to the black cohort on demographics (age, gender, insurance, income, education, county, diagnosis year), presentation (demographic variables, stage, grade, tumor size, Charlson score), and treatment (demographic and presentation variables, lymph node count, hospital volume, neoadjuvant chemotherapy [NAC], treatment delay), creating 3 matched cohorts. Chi-square and Kruskal-Wallis tests were used to compare cohorts. Kaplan-Meier analysis was used to compare 5-year overall survival (OS).

RESULTS

5-year OS rate was 40.4% and 35.6% for unmatched white and black cohorts (P < 0.001), respectively. Following demographics and presentation match, 5-year OS rate for white patients decreased to 39.2% (P = 0.003) and 39.10% (P = 0.019), respectively. After treatment match, 5-year OS rate decreased to 36.7% for white patient (P = 0.32). Following presentation match, 7.2% of black patients vs. 5.8% of white patients had treatment delay, and 10.1% of black patients vs. 11.2% of white patients received NAC. The treatment match resulted in a 0.3% difference between groups for treatment delay and NAC.

CONCLUSIONS

Our analysis demonstrates that disparity between black and white patients with muscle-invasive bladder cancer exists in demographic-, presentation-, and treatment-related variables. Treatment variables may be a large contributing factor to survival disparities. Further research is needed to identify social, biological, and organizational inputs that contribute to these disparities.

Comparison of Simulated Outcomes of Colorectal Cancer Surgery at the Highest-Performing vs Chosen Local Hospitals

IMPORTANCE

Variation in outcomes across hospitals adversely affects surgical patients. The use of high-quality hospitals varies by population, which may contribute to surgical disparities.

OBJECTIVE

To simulate the implications of data-driven hospital selection for social welfare among patients who underwent colorectal cancer surgery.

DESIGN, SETTING, AND PARTICIPANTS

This economic evaluation used the hospital inpatient file from the Florida Agency for Health Care Administration. Surgical outcomes of patients who were treated between January 1, 2016, and December 31, 2018 (training cohort), were used to estimate hospital performance. Costs and benefits of care at alternative hospitals were assessed in patients who were treated between January 1, 2019, and December 31, 2019 (testing cohort). The cohorts comprised patients 18 years or older who underwent elective colorectal resection for benign or malignant neoplasms. Data were analyzed from March to October 2022.

EXPOSURES

Using hierarchical logistic regression, we estimated the implications of hospital selection for in-hospital mortality risk in patients in the training cohort. These estimates were applied to patients in the testing cohort using bayesian simulations to compare outcomes at each patient's highest-performing and chosen local hospitals. Analyses were stratified by race and ethnicity to evaluate the potential implications for equity.

MAIN OUTCOMES AND MEASURES

The primary outcome was the mean patient-level change in social welfare, a composite measure balancing the value of reduced mortality with associated costs of care at higher-performing hospitals.

RESULTS

A total of 21 098 patients (mean [SD] age, 67.3 [12.0] years; 10 782 males [51.1%]; 2232 Black [10.6%] and 18 866 White [89.4%] individuals) who were treated at 178 hospitals were included. A higher-quality local hospital was identified for 3057 of 5000 patients (61.1%) in the testing cohort. Selecting the highest-performing hospital was associated with a 26.5% (95% CI, 24.5%-29.0%) relative reduction and 0.24% (95% CI, 0.23%-0.25%) absolute reduction in mortality risk. A mean amount of $1953 (95% CI, $1744-$2162) was gained in social welfare per patient treated. Simulated reassignment to a higher-quality local hospital was associated with a 23.5% (95% CI, 19.3%-32.9%) relative reduction and 0.26% (95% CI, 0.21%-0.30%) absolute reduction in mortality risk for Black patients, with $2427 (95% CI, $1697-$3158) gained in social welfare.

CONCLUSIONS AND RELEVANCE

In this economic evaluation, using procedure-specific hospital performance as the primary factor in the selection of a local hospital for colorectal cancer surgery was associated with improved outcomes for both patients and society. Surgical outcomes data can be used to transform care and guide policy in colorectal cancer.

Understanding Racial Differences in Lung Cancer Surgery Through a Statewide Quality Collaborative

BACKGROUND

Persistent racial disparities in lung cancer incidence, treatment, and survival are well documented. Given the importance of surgical resection for lung cancer treatment, racial disparities in surgical quality were investigated using a statewide quality collaborative.

METHODS

This retrospective study used data from the Michigan Society of Cardiothoracic Surgeons General Thoracic database, which includes data gathered for the Society of Thoracic Surgeons General Thoracic Surgery Database at 17 institutions in Michigan. Adult patients undergoing resection for lung cancer between 2015 and 2021 were included. Propensity score-weighting methodology was used to assess differences in surgical quality, including extent of resection, adequate lymph node evaluation, 30-day mortality, and 30-day readmission rate between white and black patients.

RESULTS

The cohort included 5073 patients comprising 357 (7%) black and 4716 (93%) white patients. The black patients had significantly higher unadjusted rates of wedge resection than the white patients, but after propensity score-weighting for clinical factors, wedge resection did not differ from lobectomy (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.78-1.49; P = 0.67). The black patients had fewer lymph nodes collected (incidence rate ratio [IRR], 0.77; 95% CI, 0.73-0.81; P < 0.0001) and lymph node stations sampled (IRR, 0.89; 95% CI, 0.84-0.94; P < 0.0001). The black patients did not differ from the white patients in terms of mortality (OR, 0.65; 95% CI, 0.19-2.34; P = 0.55) or readmission (OR, 0.79; 95 % CI, 0.49-1.27; P = 0.32). The black patients had longer hospital stays (OR, 1.08; 95% CI, 1.02-1.14; P = 0.01).

CONCLUSION

In a statewide quality collaborative that included high-volume centers, black patients received a less extensive lymph node evaluation, with fewer non-anatomic wedge resections performed, and a more limited lymph node evaluation with lobectomy.

Evaluation of the role of local therapy in patients with cN1M0 prostate cancer: A population-based study from the SEER database

Objective

To investigate the prognostic value of local therapy (LT) in cN1M0 prostate cancer (PCa).

Methods

Patients diagnosed with cN1M0 PCa were extracted from the surveillance, epidemiology, and end results (SEER) database. Kaplan-Meier (KM) curve was used to compare the survival outcomes between patients treated with and without LT. Further, among patients receiving LT, KM analysis was also applied to investigate the survival differences in patients with radical prostatectomy (RP) and radiation therapy (RT). Propensity score matching (PSM) analysis was performed to balance the basic characteristics of patients in each group and make it comparable when exploring the survival impact of different treatment types. Finally, uni- and multivariable Cox proportional-hazards models were utilized to identify independent prognostic factors associated with overall survival (OS) and cancer-specific survival (CSS) in this population.

Results

Patients treated with LT had significantly better OS (P<0.0001) and CSS (P<0.0001) than those without LT, as well as in most subgroups, except for non-White patients, or those with ISUP grade group 1 or T3 stage. Notably, patients receiving RP also had significantly better OS (P=0.00012) and CSS (P=0.0045) than those treated with RT alone, especially in those aged ≥75 years old, prostate-specific antigen (PSA) 10-20 ng/mL, ISUP grade 1-3 or non-white patients. Finally, clinical T stage, ISUP grade group and the administration of LT were identified to be independent prognostic factors for OS and CSS among cN1M0 PCa patients.

Conclusion

The cN1M0 PCa patients treated with LT were associated with significantly better survival. Among patients receiving LT, the combination of RP and PLND could lead to a better prognosis compared to RT alone in most subgroups. An individualized treatment strategy is warranted to be developed after weighing the benefits and risks of treatment.

Disparities in Comorbidities in Lung Cancer: Findings From the Behavioral Risk Factor Surveillance System

BACKGROUND

In persons with lung cancer, sex and race are independent predictors of comorbidities and are associated survival. It is unclear how comorbidity profiles differ across sex and race.

OBJECTIVE

The objective was to examine comorbidity differences between men and women and Blacks and Whites.

METHODS

Data from the 2014, 2016, 2017, and 2018 Behavioral Risk Factor Surveillance System were analyzed using descriptive statistics, χ2 test of independence, and multiple logistic regression. Variables included sociodemographics and comorbidities.

RESULTS

Among individuals with lung cancer (N = 594), men were more likely to experience a heart attack (odds ratio [OR], 3.59; 95% confidence interval [CI], 1.62-7.96) and diabetes (OR, 2.83; 95% CI, 1.57-5.10) and less likely to experience depressive disorder (OR, 0.360; 95% CI, 0203-0.637). Black men (OR, 28.57; 95% CI, 9.22-88.55) and women (OR, 2.48; 95% CI, 1.02-6.05) were more likely to have a history of stroke.

CONCLUSION

Findings show that there may be differences in patterns of comorbidities among individuals with lung cancer. As we continue to move toward individualized medicine in cancer care, future work in this area should examine social determinants of health and how they may influence the patterns of comorbidities.

IMPLICATION FOR NURSES

Although nurses may be aware that certain groups have an increased risk for certain comorbid conditions, this study highlights what groups with lung cancer may be more likely to have certain comorbidities. Nurses can assess individuals for comorbidities and provide education on how to manage comorbidities during cancer treatment.

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.

Racial Disparities in Colorectal Cancer Care for Black Patients: Barriers and Solutions

Racial disparities in colorectal cancer for Black patients have led to a significant mortality difference when compared to White patients, a gap which has remained to this day. These differences have been linked to poorer quality insurance and socioeconomic status in addition to lower access to high-quality health care resources, which are emblematic of systemic racial inequities. Disparities impact nearly every point along the colorectal cancer care continuum and include barriers to screening, surgical care, oncologic care, and surveillance. These critical faults are the driving forces behind the mortality difference Black patients face. Health care systems should strive to correct these disparities through both cultural competency at the provider level and public policy change at the national level.

Disparities in Health Care Spending and Utilization Among Black and White Medicaid Enrollees

Importance

Administrative records indicate that more than half of the 80 million Medicaid enrollees identify as belonging to a racial and ethnic minority group. Despite this, disparities within the Medicaid program remain understudied. For example, we know of no studies examining racial differences in Medicaid spending, a potential measure of how equitably state resources are allocated.

Objectives

To examine whether and to what extent there are differences in health care spending and utilization between Black and White enrollees in Medicaid.

Design Setting and Participants

This cross-sectional study used calendar year 2016 administrative data from 3 state Medicaid programs and included 1 966 689 Black and White Medicaid enrollees. Analyses were performed between January 28, 2021, and October 18, 2021.

Exposures

Self-reported race.

Main Outcomes and Measures

Rates and racial differences in health care spending and utilization (including Healthcare Effectiveness Data and Information Set [HEDIS] access measures).

Results

Of 1 966 689 Medicaid adults and children (mean [SD] age, 20.3 [17.1] years; 1 119 136 [56.9%] female), 867 183 (44.1%) self-identified as non-Hispanic Black and 1 099 506 (55.9%) self-identified as non-Hispanic White. Results were adjusted for age, sex, Medicaid eligibility category, zip code, health status, and usual source of care. On average, annual spending on Black adult (19 years or older) Medicaid enrollees was $317 (95% CI, $259-$375) lower than White enrollees, a 6% difference. Among children (18 years or younger), annual spending on Black enrollees was $256 (14%) lower (95% CI, $222-$290). Adult Black enrollees also had 19.3 (95% CI, 16.78-21.84), or 4%, fewer primary care encounters per 100 enrollees per year compared with White enrollees. Among children, the differences in primary care utilization were larger: Black enrollees had 90.1 (95% CI, 88.2-91.8) fewer primary care encounters per 100 enrollees per year compared with White enrollees, a 23% difference. Black enrollees had lower utilization of most other services, including high-value prescription drugs, but higher emergency department use and rates of HEDIS preventive screenings.

Conclusions and Relevance

In this cross-sectional study of US Medicaid enrollees in 3 states, Black enrollees generated lower spending and used fewer services, including primary care and recommended care for acute and chronic conditions, but had substantially higher emergency department use. While Black enrollees had higher rates of HEDIS preventive screenings, ensuring equitable access to all services in Medicaid must remain a national priority.

Are perioperative outcomes in cancer-related ventral incisional hernia repair worse than in the general population? An Abdominal Core Health Quality Collaborative (ACHQC) database study

PURPOSE

Patients with a history of cancer-related abdominal surgery undergoing incisional hernia repair (IHR) are highly heterogenous and increasingly prevalent. We explored whether cancer surgery should be considered an independent risk factor for worse IHR perioperative outcomes.

METHODS

Patients undergoing IHR between 2018 and 2020 were identified within the Abdominal Core Health Quality Collaborative (ACHQC). Regression models were used to assess associations between cancer operation history and 30 d surgical site occurrences-exclusive of infection (SSO-EIs), surgical site infections (SSIs), reoperations, time to recurrence, and quality of life (QoL) scores. Cancer cohort subgroup analysis was performed for operative approach and mesh location.

RESULTS

8019 patients who underwent IHR were identified in the ACHQC, 1321 of which had a history of cancer operation. Cancer cohort patients were more likely to be older, males with a higher ASA status and lower BMI, and have longer and wider hernias (p < 0.001). After adjusting for confounding, the cancer cohort was less likely to experience SSO-EIs (OR 0.74, 95% CI 0.59-0.94 p = 0.0092) and showed lower odds of SSIs, reoperations, and recurrence (SSI OR 0.7, 95% CI 0.47-1.05, p = 0.0542; reoperation OR 0.66, 95% CI 0.37-1.17, p = 0.1002; recurrence OR 0.8, 95% CI 0.63-1.02, p = 0.08). There was no difference in postoperative QoL scores between cohorts. There were also no differences in perioperative or QoL outcomes within the cancer cohort based on operative approach or mesh location.

CONCLUSION

These data show no evidence that history of cancer operation predisposes patients to worse incisional hernia repair perioperative or quality of life outcomes.

Access to High-Volume Hospitals for High-Risk Cancer Surgery for Racial and Ethnic Minoritized Groups

High-volume hospitals have been associated with better outcomes for high-risk cancer surgeries, although concerns exist concerning inequitable access to these high-volume hospitals. We assessed tendencies in access to high-volume hospitals for 4 (lung, pancreatic, rectal, esophageal) high-risk cancer surgeries for Black and Hispanic patients in the National Cancer Database. Hospitals were classified as high volume according to Leapfrog Group volume thresholds. Odds of accessing high-volume hospitals increased over time for Black and Hispanic patients for 3 surgeries, but Black patients had lower probabilities of undergoing a pancreatectomy, proctectomy, or esophagectomy at high-volume hospitals than non-Black patients (eg, 2016 pancreatectomy rate: 49.0% [95% confidence interval (CI) = 45.4% to 52.5%] vs 62.3% [95% CI = 61.1% to 63.5%]). Although for Hispanics the gap narrowed for lung resection and pancreatectomy, these populations continued to have lower probabilities of accessing high-volume hospitals than non-Hispanic patients (eg, 2016 pancreatectomy: 48.8% [95% CI = 44.1% to 53.5%] vs 61.6% [95% CI = 60.5% to 62.8%]). Despite increased access to high-volume hospitals for high-risk cancer surgeries, ongoing efforts to improve equity in access are needed.

Disparities in Lung Cancer Treatment

PURPOSE OF REVIEW

Despite an overall reduction in lung cancer incidence and mortality rates worldwide, Blacks still have higher mortality rates compared to Whites. There are many factors that contribute to this difference. This review seeks to highlight racial disparities in treatment and the possible reasons for these disparities.

RECENT FINDINGS

Factors attributing to racial disparities in lung cancer treatment include social determinants of health, differences in the administration of guideline-concordant therapy as well as molecular testing that is essential for most NSCLC patients. One way to circumvent disparities in lung cancer survivorship is to ensure equal representation of race in research at all levels that will provide insight on interventions that will address social determinants of health, differences in treatment patterns, molecular testing, and clinical trial involvement.

Landscape of mortality during and within thirty days after non-palliative radiotherapy across eleven major cancer types

BACKGROUND AND PURPOSE

Peri-RT mortality (death during or within 30 days of non-palliative radiotherapy) has been historically overlooked, and rates and risk factors are unclear.

MATERIALS AND METHODS

Patients with non-metastatic cancer, treated with non-palliative external beam radiation (RT) 2004-2016, were identified in the National Cancer Database for 11 cancer types: breast, prostate, non-prostate genitourinary, bone/soft tissue, gynecological, head/neck, lymphoma, gastrointestinal (GI), small cell lung, non-small cell lung, and central nervous system (CNS). Multivariable logistic regression was used to identify predictors of peri-RT mortality controlled for 17 covariates, including patient, tumor, and treatment factors.

RESULTS

Approximately 1.53 million patients were identified. Peri-RT mortality was 2.46% overall, spanning two orders of magnitude from 0.14% for breast to 8.52% for CNS. Peri-RT mortality steadily improved from 3.13% in 2004 to 1.78% in 2016 (P < .0001). Major predictors of peri-RT mortality included age, baseline comorbidity, male sex, and stage (P < .0001). Conversely, higher patient volume at the treating facility and use of more conformal RT planning techniques were moderately protective (P < .0001). Racial disparities varied based on disease site, as Black patients had increased peri-RT mortality for breast, lymphoma, and GI cancers, but not for other cancer types. Lack of private insurance was associated with substantially increased peri-RT mortality regardless of cancer type.

CONCLUSION

Peri-RT mortality varied considerably according to multiple factors. Sociodemographic differences highlight areas of health disparities and opportunities for quality improvement. Early recognition of patients at increased risk may facilitate implementation of closer monitoring or other preventive measures.

Teaching what matters: Integrating health equity education into the core surgery clerkship

BACKGROUND

Significant disparities in surgical outcomes exist. It is imperative to prepare future doctors to eliminate disparities. Our team of senior medical students developed a surgical clerkship module examining equity in prostate cancer. Student attitudes before and after a facilitated teaching session were assessed.

METHODS

A surgical equity pilot module was integrated into the core surgical clerkship starting in July 2020. This module was composed of (1) asynchronous preparatory material and (2) a synchronous interactive case discussion regarding disparities in prostate cancer. Discussion sessions were facilitated by upper-level medical students. Participants answered optional anonymous Likert-style and open-ended survey questions before and after the session. Pre- and post-responses were compared.

RESULTS

One hundred and sixteen students completed the module between July 2020 and January 2021. Pre- and post-survey response rates were 66% and 29%, respectively. At baseline, almost all students (95%) agreed knowledge of disparities would make them a better physician. However, the majority (95%) described their general knowledge of surgical disparities as "nonexistent," "poor," or "average." Most students did not have a framework for assessing causes of surgical disparities (86%) and were not aware of interventions for reducing disparities (90%). After intervention, the majority rated their knowledge of surgical disparities as "good" or "excellent" (71%; P < .001). Most students indicated they had a framework 79%; P < .001) and were aware of effective interventions (62%; P < .001).

CONCLUSION

We demonstrated a successful pilot of an equity-focused clerkship module. Student attitudes after a single session reflected significant improvement in knowledge of causes and interventions related to surgical disparities. Equity-focused teaching can be incorporated into the surgical clerkship.

Challenges in the Methodology for Health Disparities Research in Thoracic Surgery

Research on health disparities in thoracic surgery is based on large population-based studies, which is associated with certain biases. Several methodological challenges are associated with these biases and warrant review and attention. The lack of standardized definitions in health disparities research requires clarification for study design strategy. Further inconsistencies remain when considering data sources and collection methods. These inconsistencies pose challenges for accurate and standardized downstream data analysis and interpretation. These sources of bias should be considered when establishing the infrastructure of health disparities research in thoracic surgery, which is in its infancy and requires further development.

Bias Issues in Colorectal Cancer Management: A Review

Based on census data, over one-third of the US population identifies as a racial or ethnic minority. This group of racial and ethnic minorities is more likely to develop cancer and die from it when compared with the general population of the USA. These disparities are most pronounced in the African American community. Despite overall CRC rates decreasing nationally and within certain racial and ethnic minorities in the USA, there continue to be disparities in incidence and mortality when compared with non-Hispanic Whites. The disparities in CRC incidence and mortality are related to systematic racism and bias inherent in healthcare systems and society. Disparities in CRC management will continue to exist until specific interventions are implemented in the context of each racial and ethnic group. This review's primary aim is to highlight the disparities in CRC among African Americans in the USA. For surgeons, understanding these disparities is formative to creating change and improving the quality of care, centering equity for all patients.

Cultural Complications Curriculum: Applicability to Surgical Oncology Programs and Practices

Background

Recognizing the need to raise awareness of core diversity, equity, and inclusion (DEI) issues in the healthcare system, our previously developed Cultural Complications Curriculum aims to support institutions in reducing cultural error. As we continue program deployment, we discuss the opportunity to apply the Cultural Complications Curriculum to multidisciplinary audiences, such as in cancer programs.

Methods

We discuss applicability of the Cultural Complications Curriculum to cancer programs and practices, including how to tailor case discussions to oncology audiences. By emphasizing the unique characteristics of the multidisciplinary care environment and anticipating potential barriers to curriculum implementation, we demonstrate how the Cultural Complications Curriculum may support culture improvement across broad audiences.

Results

The successful application of the Cultural Complication Curriculum to multidisciplinary care programs will depend on appreciating differences in background knowledge, tailoring discussions to audience needs, and adapting material by incorporating new data and addressing emerging DEI issues. Multidisciplinary environments may require innovative approaches to education including virtual platforms, increased collaboration across centers and systems, and support from professional societies. In integrated care environments, like oncology, effective DEI discussions call for the engagement of a variety of medical specialties and departments.

Conclusions

To meet the needs of an increasingly diverse patient population and workforce, our approach to DEI education must embrace the interdependent nature of care delivery. In oncology and other multidisciplinary care environments, application of the Cultural Complications Curriculum may be the first step to combating cultural error by engaging a broader demographic within our healthcare system.
