From understanding to action: interventions for surgical disparities

Racial Disparities in Perioperative Outcomes for Patients With Head and Neck Cancer

OBJECTIVE

To characterize the perioperative complications after ablative and reconstructive surgery in patients with head and neck cancer (HNC) based on race.

METHODS

We conducted a retrospective study of the 2015-2020 National Surgical Quality Improvement Program Database. We compared the perioperative outcomes between White, Asian, Black, Native Hawaiian or Pacific Islander, and American Indian or Alaskan Native patients with bivariate analysis. Multivariate logistic regression assessed the independent association of race with perioperative complications.

RESULTS

Black patients experienced longer surgeries (aβ, 43; 95% CI, 33, 53), longer hospital stays (aβ, 1.6 [95% CI, 1.1-2.1]), and were less likely to be discharged home (aOR, 0.64; [95% CI, 0.54, 0.76]). Black patients also had higher major complications risk (aOR, 1.38; [95% CI, 1.13-1.67]) with the most common being reintubation/ventilation (Black, 4.4% vs. White 2.7%; p = 0.003) and sepsis/septic shock (Black, 3.4% vs. White 1.8%; p = < 0.001). Black patients had higher reoperation rates (aOR, 1.33; [95% CI, 1.12-1.56]) with incision and drainage of abscess and hematoma, exploration of postoperative hemorrhage, thrombosis or infection, or surgical debridement being the top reasons for reoperation. Concordantly, they were at higher risk of postoperative transfusion (Black, 18%; White, 7.2%; p = < 0.001) and wound dehiscence (Black, 4.1%; White, 2.1%; p = < 0.001).

CONCLUSION

There is evidence of racial disparities in HNC surgery perioperatively. Black patients face an increased risk of major complications, reoperation, extended hospital stay, and non-home discharge. Developing a comprehensive surgical database with more social determinants of health variables and using a socioecological framework of health can help us identify contributors to these disparities and design high-leverage solutions.

Persistent Racial Disparities in Morbidity Following Major Elective Operations

Introduction: Despite considerable national attention, racial disparities in surgical outcomes persist. We sought to consider whether race-based inequities in outcomes following major elective surgery have improved in the contemporary era. Methods: All adult hospitalization records for elective coronary artery bypass grafting, abdominal aortic aneurysm repair, colectomy, and hip replacement were tabulated from the 2016-2020 National Inpatient Sample. Patients were stratified by Black or White race. To consider the evolution in outcomes, we included an interaction term between race and year. We designated centers in the top quartile of annual procedural volume as high-volume hospitals (HVH). Results: Of ∼2,838,485 patients, 245,405 (8.6%) were of Black race. Following risk-adjustment, Black race was linked with similar odds of in-hospital mortality, but increased likelihood of major complications (Adjusted Odds Ratio [AOR] 1.41, 95%Confidence Interval [CI] 1.36-1.47). From 2016-2020, overall risk-adjusted rates of major complications declined (patients of White race: 9.2% to 8.4%; patients of Black race 11.8% to 10.8%, both P < .001). Yet, the delta in risk of adverse outcomes between patients of White and Black race did not significantly change. Of the cohort, 158,060 (8.4%) were treated at HVH. Following adjustment, Black race remained associated with greater odds of morbidity (AOR 1.37, CI 1.23-1.52; Ref:White). The race-based difference in risk of complications at HVH did not significantly change from 2016 to 2020. Conclusion: While overall rates of complications following major elective procedures declined from 2016 to 2020, patients of Black race faced persistently greater risk of adverse outcomes. Novel interventions are needed to address persistent racial disparities and ensure acceptable outcomes for all patients.

Health Disparities Research: What Every Pediatric Surgeon Should Know

While the earliest published health disparity research in the United States dates to 1899, the field was not formally established until the late 20th century. Initially focused on race and ethnicity, the field has broadened to include socioeconomic status. Several measures have been developed to quantify socioeconomic disadvantage, including the Social Vulnerability Index, Area Deprivation Index, and Child Opportunity Index. These indices have been validated and demonstrate correlation with health outcomes. However, socioeconomic status cannot fully explain health inequities experienced by people of minoritized racial and ethnic identities. Three generations of health disparities research have been described-identification of disparities, root analysis, and development of interventions to mitigate health inequities. While there has been an increase in publication of health disparity research, there is little third generation work. It is imperative that health disparities research move beyond defining the problem and toward interventions that will reduce health inequities. LEVELS OF EVIDENCE: Level IV.

Racial disparities in the utilization and outcomes of robotic bariatric surgery: an 8-year analysis of Metabolic and Bariatric Surgery Accreditation Quality Improvement Program data

BACKGROUND

Robotic surgery utilization has been increasing across surgical specialties; however, racial disparities in patient access to care and outcomes have been reported.

OBJECTIVES

In this study, we examined racial disparities in the utilization and outcomes of robotic bariatric surgery over an 8-year period.

SETTING

Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP) centers of excellence across the United States.

METHODS

The MBSAQIP database was used to identify adult patients who underwent robotic bariatric surgery between 2015 and 2022. Patients were stratified according to race and ethnicity into non-Hispanic White, non-Hispanic Black or African American (AA), Indigenous, Asian, and Hispanic patients. Multivariable analyses were used to assess predictors of robotic surgery use, odds of minor and major complications, prolonged length of stay (prolonged length of stay (pLOS): ≥3 days), readmissions, reoperations, and mortality within 30 days.

RESULTS

Out of 1,288,359 patients included, robotic surgery was utilized in 196,314 patients (15.2%), with a mean age of 44 ± 12 years and 80.6% females. Rates of robotic surgery increased to 30% by 2022. Compared to White patients, Black/AA patients were more likely to undergo robotic surgery (adjusted odds ratio (aOR) = 1.22, 95% confidence interval (CI) = 1.21-1.24, P < .001). The safety of robotic bariatric surgery improved for both White and Black patients with decreased odds of major complications, readmissions, reoperations, and pLOS over the study period. However, Black/AA patients were more likely to experience minor and major complications, readmissions and have pLOS compared with White patients in 2022 (aOR:1.26, 95% CI:1.19-1.34, P < .001; aOR:1.22, 95% CI:1.06-1.41, P = .006; aOR:1.44, 95% CI:1.28-1.62, P < .001; aOR:2.26, 95% CI:2.06-2.47, P < .001, respectively).

CONCLUSION

The utilization of robotic bariatric surgery has increased significantly over the past 8 years with continued improvements in its safety profile. While Black/AA patients have improved access to robotic surgery, their clinical outcomes continue to be worse than those of White patients. Efforts to address racial disparities in bariatric surgery outcomes must remain a priority to achieve health equity.

Disparities in pathways to reduction mammaplasty: A single institution review of 425 women with macromastia

BACKGROUND

Reduction mammaplasty improves the quality of life by providing functional and aesthetic benefits to women with macromastia. This study contributes to the existing literature on socioeconomic and clinical barriers to referral for plastic surgery procedures by focusing specifically on reduction mammaplasty.

METHODS

Patients with macromastia were identified via a chart review in a single institution from 2021-2022. The treatment pathway for each patient was characterized by reception of referral, completion of plastic surgery consultation, and eventual reception of surgery. After controlling for clinical covariates, multivariate logistic regression was applied to quantify the independent impact of race, insurance, and language status on the completion of surgery (p < 0.05).

RESULTS

The final patient cohort included 425 women with macromastia. Among the 151 patients who were first seen by a primary care physician, 64 (42%) completed an initial plastic surgery consultation. Among all patients, 160 (38%) eventually underwent reduction mammaplasty. Multivariate regression predictions indicated a lower likelihood of completing breast reduction surgery in patients with current smoking history (OR: 0.08, 95% CI: 0.01-0.59) and higher body mass index (BMI) (OR: 0.94, 95% CI: 0.90-0.97) (p < 0.05). Minority race and ethnicity, private insurance status, and primary language status were not significant predictors of this outcome (p > 0.05).

CONCLUSIONS

In this study, the socioeconomic variables were not independent predictors of breast reduction surgery completion. However, the association of minority race and ethnicity and nonprivate insurance status with the most common reasons for breast reduction deferral suggest an indirect influence of socioeconomic status on the treatment pathway.

Racial Disparities in Bowel Preparation and Post-Operative Outcomes in Colorectal Cancer Patients

BACKGROUND

Combined pre-operative bowel preparation with oral antibiotics (OAB) and mechanical bowel preparation (MBP) is the current recommendation for elective colorectal surgery. Few have studied racial disparities in bowel preparation and subsequent post-operative complications.

METHODS

This retrospective cohort study used 2015-2021 ACS-NSQIP-targeted data for elective colectomy for colon cancer. Multivariate regression evaluated predictors of post-operative outcomes: post-operative ileus, anastomotic leak, surgical site infection (SSI), operative time, and hospital length of stay (LOS).

RESULTS

72,886 patients were evaluated with 82.1% White, 11.1% Black, and 6.8% Asian or Asian Pacific Islander (AAPI); 4.2% were Hispanic and 51.4% male. Regression accounting for age, sex, ASA classification, comorbidities, and operative approach showed Black, AAPI, and Hispanic patients were more likely to have had no bowel preparation compared to White patients receiving MBP+OAB. Compared to White patients, Black and AAPI patients had higher odds of prolonged LOS and pro-longed operative time. Black patients had higher odds of post-operative ileus.

CONCLUSIONS

Racial disparities exist in both bowel preparation administration and post-operative complications despite the method of bowel preparation. This warrants exploration into discriminatory bowel preparation practices and potential differences in the efficacy of bowel preparation in specific populations due to biological or social differences, which may affect outcomes. Our study is limited by its use of a large database that lacks socioeconomic variables and patient data beyond 30 days.

Impact of Racial/Ethnic Disparities on Patient-Reported Outcomes Following Cervical Spine Surgery: QOD Analysis

STUDY DESIGN

Retrospective analysis of data from the cervical module of a National Spine Registry, the Quality Outcomes Database.

OBJECTIVE

To examine the association of race and ethnicity with patient-reported outcome measures (PROMs) at one year after cervical spine surgery.

SUMMARY OF BACKGROUND DATA

Evidence suggests that Black individuals are 39% to 44% more likely to have postoperative complications and a prolonged length of stay after cervical spine surgery compared with Whites. The long-term recovery assessed with PROMs after cervical spine surgery among Black, Hispanic, and other non-Hispanic groups ( i.e . Asian) remains unclear.

MATERIALS AND METHODS

PROMs were used to assess disability (neck disability index) and neck/arm pain preoperatively and one-year postoperative. Primary outcomes were disability and pain, and not being satisfied from preoperative to 12 months after surgery. Multivariable logistic and proportional odds regression analyses were used to determine the association of racial/ethnic groups [Hispanic, non-Hispanic White (NHW), non-Hispanic Black (NHB), and non-Hispanic Asian (NHA)] with outcomes after covariate adjustment and to compute the odds of each racial/ethnic group achieving a minimal clinically important difference one-year postoperatively.

RESULTS

On average, the sample of 14,429 participants had significant reductions in pain and disability, and 87% were satisfied at one-year follow-up. Hispanic and NHB patients had higher odds of not being satisfied (40% and 80%) and having worse pain outcomes (30%-70%) compared with NHW. NHB had 50% higher odds of worse disability scores compared with NHW. NHA reported similar disability and neck pain outcomes compared with NHW.

CONCLUSIONS

Hispanic and NHB patients had worse patient-reported outcomes one year after cervical spine surgery compared with NHW individuals, even after adjusting for potential confounders, yet there was no difference in disability and neck pain outcomes reported for NHA patients. This study highlights the need to address inherent racial/ethnic disparities in recovery trajectories following cervical spine surgery.

Impact of Sociodemographic and Hospital Factors on Inpatient Bilateral Reduction Mammaplasty: A National Inpatient Sample Analysis

Background

Although reduction mammaplasty remains a common procedure in plastic surgery, its interaction with sociodemographic and economic disparities has remained relatively uncharacterized on a nationwide scale.

Methods

Patients who underwent reduction mammaplasty were identified within the 2016-2018 National Inpatient Sample databases. In addition to clinical comorbidities, sociodemographic characteristics, hospital-level variables, and postoperative outcomes of each patient were collected for analysis. Statistical analyses, including univariate comparison and multivariate logistic regression, were applied to the cohort to determine significant predictors of adverse outcomes, described as extended length of stay, higher financial cost, and postoperative complications.

Results

The final patient cohort included 414 patients who underwent inpatient reduction mammaplasty. The average age was 45.2 ± 14.5 years. The average length of stay was 1.6 ± 1.5 days, and the average hospital charge was $53,873.81 ± $36,014.50. Sixty (14.5%) patients experienced at least one postoperative complication. Black race and treatment within a nonmetropolitan or rural county predicted postoperative complications (P < 0.01). Black race, lower relative income, and concurrent abdominal contouring procedures also predicted occurrence of extended length of stay (P < 0.01). Hospital factors, including larger bed capacity and for-profit ownership, predicted high hospital charges (P < 0.05). Severity of comorbidities, measured by a clinical index, also predicted all three outcomes (P < 0.001).

Conclusion

In addition to well-described clinical variables, multiple sociodemographic and economic disparities affect outcomes in inpatient reduction mammaplasty.

Inefficiency in Delivery of General Surgery to Black Patients: A National Inpatient Sample Study

Background  Racial disparities in outcomes among patients in the United States are widely recognized, but disparities in treatment are less commonly understood. This study is intended to identify treatment disparities in delivery of surgery and time to surgery for diagnoses managed by general surgeons-appendicitis, cholecystitis, gallstone pancreatitis, abdominal wall hernias, intestinal obstructions, and viscus perforations. Methods  The National Inpatient Sample (NIS) was used to estimate and analyze disparities in delivery of surgery, type of surgery received, and timing of surgery. Age-adjusted means were compared by race/ethnicity and trends in treatment disparities were evaluated from 1993 to 2017. Linear modeling was used to measure trends in treatment and outcome disparities over time. Mediation analysis was performed to estimate contributions of all available factors to treatment differences. Relationships between treatment disparities and disparities in mortality and length of stay were similarly evaluated. Results  Black patients were less likely to receive surgery for appendicitis, cholecystitis, pancreatitis, and hernias, and more likely to receive surgery for obstructions and perforations. Black patients experienced longer wait times prior to surgery, by 0.15 to 1.9 days, depending on the diagnosis. Mediation analysis demonstrated that these disparities are not attributable to the patient factors available in the NIS, and provided some insight into potential contributors to the observed disparities, such as hospital factors and socioeconomic factors. Conclusion  Treatment disparities are present even with common indications for surgery, such as appendicitis, cholecystitis, and gallstone pancreatitis. Black patients are less likely to receive surgery with these diagnoses and must wait longer for surgery if it is performed. Surgeons should plan institution-level interventions to measure, explain, and potentially correct treatment disparities.

Racial disparities in time to laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND

Disparities in healthcare exist, yet few data are available on racial differences in time from admission to surgery. This study aimed to compare time from admission to laparoscopic cholecystectomy for acute cholecystitis between non-Hispanic Black and non-Hispanic White patients.

METHODS

Patients who underwent laparoscopic cholecystectomy for acute cholecystitis from 2010 to 2020 were identified using NSQIP. Time to surgery and additional preoperative, operative, and postoperative variables were analyzed.

RESULTS

In the univariate analysis, 19.4% of Black patients experienced a time to surgery >1 day compared with 13.4% of White patients (p < 0.0001). In the multivariable analysis, controlling for potential confounding factors, Black patients were found to be more likely than White patients to experience a time to surgery >1 day (OR 1.23, 95% CI 1.17-1.30, p < 0.0001).

CONCLUSIONS

Further investigation is indicated to better define the nature and significance of gender, race, and other biases in surgical care. Surgeons should be aware that biases may adversely impact patient care and should strive to identify and proactively address them to promote health equity in surgery.

National trends in distribution of underrepresented minorities within United States general surgery residency programs: A longitudinal panel study

BACKGROUND

Cultural affinity with a provider improves satisfactoriness of healthcare. We examined 2005-2019 trends in racial/ethnic diversity/inclusion within general surgery residency programs.

METHODS

We triangulated 2005-2019 race/ethnicity data from Association of American Medical Colleges surveys of 4th-year medical students, the Electronic Residency Application Service, and Accreditation Council for Graduate Medical Education-affiliated general surgery residencies. Temporal trends in minority representation were tested for significance.

RESULTS

Underrepresented racial/ethnic minorities in medicine (URiMs) increased among graduating MDs from 7.6% in 2005 to 11.8% in 2019 (p < 0.0001), as did their proportion among surgery residency applicants during 2005-2019 (p < 0.0001). However, proportions of URiMs among general surgery residents (≈8.5%), and of programs without URiMs (≈18.8%), stagnated.

CONCLUSIONS

Growing URiM proportions among medical school graduates and surgery residency applicants did not improve URiM representation among surgery trainees nor shrink the percentage of programs without URiMs. Deeper research into motivators underlying URiMs' residency program preferences is warranted.

Healthcare Disparities in Interventional Radiology

Racial, ethnic, and sex-based healthcare disparities have been documented for the past several decades. Nonetheless, disparities remain firmly entrenched in our care delivery systems, with multiple contributing factors, including patient interactions with care providers, systemic barriers to access, and socioeconomic determinants of health. Interventional radiology is also subject to these drivers of health inequity. In this review, documented disparities for the most common conditions being addressed by interventional radiologists are summarized; their magnitude is quantified where relevant, and underlying drivers are identified. Specific examples are provided to illustrate how medical, cultural, and socioeconomic factors interact to produce unequal outcomes. By outlining known disparities and common contributors, this review aims to motivate future efforts to mitigate them.

Socioeconomic disparities in abdominal aortic aneurysm repair rates and survival

BACKGROUND

Abdominal aortic aneurysm (AAA) is more prevalent in socioeconomically disadvantaged areas. This study investigated socioeconomic disparities in AAA repair rates and survival.

METHODS

The study used ecological and cohort study designs, from 31 672 census areas in England (April 2006 to March 2018), the Index of Multiple Deprivation 2010 as the area-level deprivation indicator, and Poisson, logistic and Cox regression.

RESULTS

Some 77 606 patients (83.4 per cent men) in four age categories (55-64, 65-74, 75-84, 85 or more years) were admitted with AAA from a population aged at least 55 years of 14.7 million. Elective open and endovascular repair rates were 41 (95 per cent c.i. 23 to 61) and 60 (36 to 89) per cent higher respectively among men aged 55-64 years in the most versus least deprived areas by quintile. This differences diminished and appeared to reverse with increasing age, with 26 (-1 to 45) and 25 (13 to 35) per cent lower rates respectively in men aged 85 years or more in the most deprived areas. Men admitted from more deprived areas were more likely to die in hospital without aneurysm repair. Among those who had aneurysm repair, this was more likely to be for a ruptured aneurysm than among men from less deprived areas. For intact aneurysm repair, they were relatively more likely to have this during an emergency admission. The mortality rate after repair was higher for men from more deprived areas, although the hazard diminished with age. Patterns were unclear for women.

CONCLUSION

There were clear socioeconomic disparities in operation rates, mode of presentation, and outcome for AAA surgery. Policies are needed to address these disparities.

Disparate Access to Surgery for Operable Carcinoma of the Lung in North Carolina

PURPOSE

Disparities in access to surgical care are associated with poorer outcomes in patients with cancer. We sought to determine whether vulnerable populations undergo an expected rate of surgery for Stage I-IIIA lung cancer in North Carolina (NC).

METHODS

We calculated the proportional surgical ratio (PSR) to identify a potential disparity in surgery rates for early stage (I-IIIA) lung cancer, first in the five counties with the worst health outcomes (LRC) and subsequently the entire state. The reference was the five healthiest counties (HRC), initially, and then the single county with the best health outcomes.

RESULTS

In 2016, 3,452 individuals with Stage I-IIIA lung cancer were diagnosed in NC of which 246,854 resided in LRC, whereas 1,865,588 resided in HRC. A total of 453 operable lung cancers were diagnosed in the HRC and 107 in the LRC. The observed lobectomy rate in HRC was 40.1% (range 20.2-58.3%) of early-stage lung cancer and 19% (range 12-36%) for LRC. The PSR was 0.65 (95% confidence interval [CI] = 0.35, 0.90). For all 99 counties across NC, the PSR ranged from 0.33 to 0.96 (mean = 0.49, standard deviation [SD] = 0.10). In a multivariable model, only other primary care provider ratio (relative rate per 100 increase = 0.997; 95% CI = 0.994, 0.999) was significantly associated with PSR.

CONCLUSIONS

Individuals residing in LRC in NC are 42% less likely to undergo surgery for operable lung cancer than patients living in HRC. Understanding how factors impact access is key to designing informed interventions.

Community Based Participatory Research (CBPR): An Underutilized Approach to Address Surgical Disparities

Disparities are well-documented across the continuum of surgical care. Counteracting such disparities requires new multidisciplinary approaches that utilize the expertise of affected individuals, such as community-based participatory research (CBPR). CBPR is an approach to research that is anchored in equitable, sustainable community-academic partnerships, and has been shown to improve intervention implementation and outcomes. In this article, community stakeholders and researchers outline the principles and benefits of CBPR, examples of CBPR in trauma and transplant, and future directions for CBPR within surgery.

The Impact of Socioeconomic Deprivation on Clinical Outcomes for Pancreatic Adenocarcinoma at a High-volume Cancer Center: A Retrospective Cohort Analysis

OBJECTIVE

To assess the impact of a granular measure of SED on pancreatic surgical and cancer-related outcomes at a high-volume cancer center that employs a standardized clinic pathway.

SUMMARY OF BACKGROUND DATA

Prior research has shown that low socioeconomic status leads to less treatment and worse outcomes for PDAC. However, these studies employed inconsistent definitions and categorizations of socioeconomic status, aggregated individual socioeconomic data using large geographic areas, and lacked detailed clinicopathologic variables.

METHODS

We conducted a retrospective cohort study of 1552 PDAC patients between 2008 and 2015. Patients were stratified using the area deprivation index, a validated dataset that ranks census block groups based on SED. Multivariable models were used in the curative surgery cohort to predict the impact of SED on (1) grade 3/4 Clavien-Dindo complications, (2) initiation of adjuvant therapy, (3) completion of adjuvant therapy, and (4) overall survival.

RESULTS

Patients from high SED neighborhoods constituted 29.9% of the cohort. Median overall survival was 28 months. The rate of Clavien-Dindo grade 3/4 complications was 14.2% and completion of adjuvant therapy was 65.6%. There was no evidence that SED impacted surgical evaluation, receipt of curative-intent surgery, postoperative complications, receipt of adjuvant therapy or overall survival.

CONCLUSIONS

Although nearly one-quarter of curative-intent surgery patients were from high SED neighborhoods, this factor was not associated with measures of treatment quality or survival. These observations suggest that treatment at a high-volume cancer center employing a standardized clinical pathway may in part address socioeconomic disparities in pancreatic cancer.

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.

Health Equity and Healthcare Disparities in Plastic Surgery: What We Can Do

Amidst the unexpected losses and challenges of 2020, healthcare disparities and health equity have presided as noteworthy topics of national discussion among healthcare workers, governmental officials, and society at large. Health equity, defined as the opportunity for everyone to be as healthy as possible, may be achieved through the alleviation of healthcare disparities. Healthcare disparities are defined as "preventable differences in the burden of disease, injury, violence, or opportunities to achieve optimal health that are experienced by socially disadvantaged populations." While these concepts may be perceived as a departure from the core responsibility of plastic surgeons, it is of paramount importance to recognize how race, socioeconomic status (SES), and physical environment impact access to care, surgical outcomes, and postoperative recovery for vulnerable populations. In this communication, our purpose is two-fold: 1) to elucidate the existent healthcare disparities and associations with race and SES in craniofacial, trauma, breast, hand, and gender-affirming reconstruction; and 2) provide tangible recommendations to incorporate the concepts of health equity and healthcare disparities in clinical, research, community, and recruitment settings for plastic surgeons. Through such knowledge, plastic surgeons may glean important insights that may enhance the delivery of equitable and accessible care for patients.

Understanding Racial Disparities in Gastrointestinal Cancer Outcomes: Lack of Surgery Contributes to Lower Survival in African American Patients

BACKGROUND

Race/ethnicity-related differences in rates of cancer surgery and cancer mortality have been observed for gastrointestinal (GI) cancers. This study aims to estimate the extent to which differences in receipt of surgery explain racial/ethnic disparities in cancer survival.

METHODS

The National Cancer Database was used to obtain data for patients diagnosed with stage I-III mid-esophageal, distal esophagus/gastric cardia (DEGC), noncardia gastric, pancreatic, and colorectal cancer in years 2004-2015. Mediation analysis was used to identify variables influencing the relationship between race/ethnicity and mortality, including surgery.

RESULTS

A total of 600,063 patients were included in the study: 3.5% mid-esophageal, 12.4% DEGC, 4.9% noncardia gastric, 17.0% pancreatic, 40.1% colon, and 22.0% rectal cancers. The operative rates for Black patients were low relative to White patients, with absolute differences of 21.0%, 19.9%, 2.3%, 8.3%, 1.6%, and 7.7%. Adjustment for age, stage, and comorbidities revealed even lower odds of receiving surgery for Black patients compared with White patients. The observed HRs for Black patients compared with White patients ranged from 1.01 to 1.42. Mediation analysis showed that receipt of surgery and socioeconomic factors had greatest influence on the survival disparity.

CONCLUSIONS

The results of this study indicate that Black patients appear to be undertreated compared with White patients for GI cancers. The disproportionately low operative rates contribute to the known survival disparity between Black and White patients.

IMPACT

Interventions to reduce barriers to surgery for Black patients should be promoted to reduce disparities in GI cancer outcomes.See related commentary by Hébert, p. 438.

Does Universal Insurance and Access to Care Influence Disparities in Outcomes for Pediatric Patients with Osteomyelitis?

BACKGROUND

Healthcare disparities are an issue in the surgical management of orthopaedic conditions in children. Although insurance expansion efforts may mitigate racial disparities in surgical outcomes, prior studies have not examined these effects on differences in pediatric orthopaedic care. To assess for racial disparities in pediatric orthopaedic care that may persist despite insurance expansion, we performed a case-control study of the outcomes of children treated for osteomyelitis in the TRICARE system, the healthcare program of the United States Department of Defense and a model of universal insurance and healthcare access.

QUESTIONS/PURPOSES

We asked whether (1) the rates of surgical intervention and (2) 90-day outcomes (defined as emergency department visits, readmission, and complications) were different among TRICARE-insured pediatric patients with osteomyelitis when analyzed based on black versus white race and military rank-defined socioeconomic status.

METHODS

We analyzed TRICARE claims from 2005 to 2016. We identified 2906 pediatric patients, of whom 62% (1810) were white and 18% (520) were black. A surgical intervention was performed in 9% of the patients (253 of 2906 patients). The primary outcome was receipt of surgical intervention for osteomyelitis. Secondary outcomes included 90-day complications, readmissions, and returns to the emergency department. The primary predictor variables were race and sponsor rank. Military rank has been used as an indicator of socioeconomic status before and during enlistment, and enlisted service members, particularly junior enlisted service members, may be at risk of having the same medical conditions that affect civilian members of lower socioeconomic strata. Patient demographic information (age, sex, race, sponsor rank, beneficiary category [whether the patient is an insurance beneficiary from an active-duty or retired service member], and geographic region) and clinical information (prior comorbidities, environment of care [whether clinical care was provided in a civilian or military facility], treatment setting, and length of stay) were used as covariates in multivariable logistic regression analyses.

RESULTS

After controlling for demographic and clinical factors including age, sex, sponsor rank, beneficiary category, geographic region, Charlson comorbidity index (as a measure of baseline health), environment of care, and treatment setting (inpatient versus outpatient), we found that black children were more likely to undergo surgical interventions for osteomyelitis than white children (odds ratio 1.78; 95% confidence interval, 1.26-2.50; p = 0.001). When stratified by environment of care, this finding persisted only in the civilian healthcare setting (OR 1.85; 95% CI, 1.26-2.74; p = 0.002). Additionally, after controlling for demographic and clinical factors, lower socioeconomic status (junior enlisted personnel) was associated with a higher likelihood of 90-day emergency department use overall (OR 1.60; 95% CI, 1.02-2.51; p = 0.040).

CONCLUSIONS

We found that for pediatric patients with osteomyelitis in the universally insured TRICARE system, many of the historically reported disparities in care were absent, suggesting these patients benefitted from improved access to healthcare. However, despite universal coverage, racial disparities persisted in the civilian care environment, suggesting that no single intervention such as universal insurance sufficiently addresses differences in racial disparities in care. Future studies can address the pervasiveness of these disparities in other patient populations and the various mechanisms through which they exert their effects, as well as potential interventions to mitigate these disparities.

National trends in ventral hernia repairs for patients with intra-abdominal metastases

BACKGROUND

Ventral hernias in patients with intra-abdominal metastases may not be addressed owing to other oncologic priorities, but they can affect quality of life and lead to sequelae necessitating an emergency operation. We compared the national trends and perioperative outcomes for elective and nonelective ventral hernia repairs for patients with intra-abdominal metastases.

METHODS

Patients were identified from the National Inpatient Sample (2003-2015). Temporal trends were described using average annual percent change. Perioperative outcomes between elective and nonelective ventral hernia repairs were compared using multivariable regressions.

RESULTS

An estimated 947,112 ventral hernia repairs were performed nationally, including 5,602 (0.6%) in patients with intra-abdominal metastases. Among patients with intra-abdominal metastases, 40.1% had a nonelective ventral hernia repair, mean (standard deviation) age was 64 (12) years, and 65.1% were women. Between 2003 and 2015, the total number of ventral hernia repairs performed nationally did not change (average annual percent change 0.062, P = .84). For patients with intra-abdominal metastases, although there was no change in the number of elective ventral hernia repairs (average annual percent change 0.65, P = .59), the number of nonelective ventral hernia repairs increased significantly (average annual percent change 2.7, P = .025). By multivariable analyses, patients with intra-abdominal metastases who underwent a nonelective repair were more likely to experience complications (odds ratio 1.76, P = .001), nonroutine discharge (odds ratio 1.93, P < .001), and mortality (odds ratio 2.27, P = .035). Nonelective ventral hernia repairs was also associated with a 38.5% (P < .001) longer hospital stay and 24.4% (P < .001) higher charges.

CONCLUSION

The number of nonelective ventral hernia repairs, which is associated with substantial perioperative morbidity, has increased significantly among patients with intra-abdominal metastases. Surgeons should consider a nonemergency operation for select patients to mitigate the burden of nonelective ventral hernia repairs.

Racial Disparity in Cardiac Surgery Risk and Outcome: Report From a Statewide Quality Initiative

BACKGROUND

Racial disparities persist in health care. Our study objective was to evaluate racial disparity in cardiac surgery in Maryland.

METHODS

A statewide database was used to identify patients. Demographics, comorbidities, and predicted risk of death were compared between races. Crude mortality and incidence of complications were compared between groups, as were risk-adjusted odds for mortality and major morbidity or mortality.

RESULTS

The study included 23,094 patients. Most patients were white (75.8%), followed by African American (16.3%), Asian (3.8%), and other races (4.1%). African Americans had a higher preoperative risk for mortality based on The Society of Thoracic Surgeons predictive models compared with white patients (3.0% vs 2.3%, P < .001). African Americans also had higher prevalence of diabetes mellitus, hypertension, peripheral vascular disease, and cerebral vascular disease than white patients. After adjustment for preoperative risk, there was no difference in 30-day mortality between African Americans (odds ratio [OR], 1.26; 95% confidence interval [CI], 0.99-1.59), Asians (OR, 1.22; 95% CI, 0.75-1.97), and other races (OR, 1.18; 95% CI, 0.74-1.89) compared with whites. African Americans had lower risk-adjusted odds of major morbidity or mortality compared with whites (OR, 0.83; 95% CI, 0.75-0.93).

CONCLUSIONS

African American cardiac surgical patients have the highest preoperative risk in Maryland. Patients appeared to receive excellent cardiac surgical care, regardless of race, as risk-adjusted mortality did not differ between groups, and African American patients had lower risk-adjusted odds of major morbidity or mortality than white patients. Future interventions in Maryland should be aimed at reducing preoperative risk disparity in cardiac surgical patients.

Trends and Disparities in Inpatient Costs for Eye Trauma in the United States (2001-2014)

PURPOSE

To determine the trends and disparities in inpatient costs for eye trauma in the United States from 2001 through 2014.

DESIGN

Retrospective population-based cross-sectional study.

METHODS

National Inpatient Sample, a representative sample of U.S. hospital discharges, was used to determine costs of eye trauma hospitalizations. Linear regression was used to estimate changes in mean inflation-adjusted cost per admission. Multivariable logistic regression was used to evaluate factors associated with a cost in the highest quartile (>$13 000) including age, sex, race, income quartile, primary payer, hospital location, size, and type. The model was adjusted for year of admission, length of stay, type of trauma, comorbidities, and the type and number of procedures performed.

RESULTS

The inpatient costs for eye trauma from 2001 through 2014 totaled $1.72 billion. The mean cost (95% confidence interval [CI]) per stay remained relatively constant: $12 000 ($11 000-13 000) in 2001 to $11 000 ($10 000-12 000) in 2014 (P = .643). A cost in the highest quartile was more likely in African Americans compared to whites (adjusted odds ratio, 1.3; 95% CI, 1.2-1.5), patients in the highest income quartile compared to those in the lowest (1.3; 1.2-1.5), uninsured patients compared to publicly insured patients (1.2; 1.1-1.4), teaching hospitals compared to non-teaching ones (1.5; 1.2-1.8), and the West compared to the South (2.4; 2.0-2.8).

CONCLUSIONS

Inpatient costs of eye trauma have remained steady and can be potentially reduced by addressing associated disparities. Further research including outpatient costs and eye trauma in vulnerable populations will be key to optimizing care and advancing healthcare equity.

Granulocyte Colony-Stimulating Factor Combined with Methylprednisolone Improves Functional Outcomes in Rats with Experimental Acute Spinal Cord Injury

OBJECTIVES

To evaluate the effects of combined treatment with granulocyte colony-stimulating factor (G-CSF) and methylprednisolone in rats subjected to experimental spinal cord injury.

METHODS

Forty Wistar rats received a moderate spinal cord injury and were divided into four groups: control (no treatment); G-CSF (G-CSF at the time of injury and daily over the next five days); methylprednisolone (methylprednisolone for 24 h); and G-CSF/Methylprednisolone (methylprednisolone for 24 h and G-CSF at the time of injury and daily over the next five days). Functional evaluation was performed using the Basso, Beattie and Bresnahan score on days 2, 7, 14, 21, 28, 35 and 42 following injury. Motor-evoked potentials were evaluated. Histological examination of the spinal cord lesion was performed immediately after euthanasia on day 42.

RESULTS

Eight animals were excluded (2 from each group) due to infection, a normal Basso, Beattie and Bresnahan score at their first evaluation, or autophagy, and 32 were evaluated. The combination of methylprednisolone and G-CSF promoted greater functional improvement than methylprednisolone or G-CSF alone (p<0.001). This combination also exhibited a synergistic effect, with improvements in hyperemia and cellular infiltration at the injury site (p<0.001). The groups displayed no neurophysiological differences (latency p=0.85; amplitude p=0.75).

CONCLUSION

Methylprednisolone plus G-CSF promotes functional and histological improvements superior to those achieved by either of these drugs alone when treating spinal cord contusion injuries in rats. Combining the two drugs did have a synergistic effect.

Race and postoperative complications following urologic cancer surgery: An ACS-NSQIP analysis

PURPOSE

Racial disparities in complication rates have been demonstrated for a variety of surgical procedures. We hypothesized that African American (AA) patients experience higher postoperative complication rates than whites following urologic oncology procedures.

MATERIALS AND METHODS

Patients in American College of Surgeons National Surgical Quality Improvement Program who underwent radical prostatectomy (RP), radical or partial nephrectomy (RN/PN), and radical cystectomy (RC) between 2005 and 2013 were included. Complications were grouped as minor (Clavien I-II), major (Clavien III-IV), or death (Clavien V). A 30-day complication rates and disparities in preoperative comorbidity burden were compared by race. After adjustment for comorbidity burden, multivariable logistic regression was performed to test the association between race and risk of complication.

RESULTS

Of 38,642 patients included in the analysis, 90% were white and 10% were AA. In unadjusted analysis, there were no significant differences in complication rates between AA and white patients for any Clavien grade in the procedures queried (RP: P = 0.07; RN/PN: P = 0.70; RC: P = 0.12). After controlling for a higher comorbidity burden among AA patients, AA race was again not independently associated with 30-day postoperative complications for RP (odds ratio [OR] = 1.08, 95% CI: 0.92-1.29), RN/PN (OR = 0.98, 95% CI: 0.84-1.13), or RC (OR = 1.10, 95% CI: 0.84-1.43).

CONCLUSION

Despite a higher comorbidity burden, AA patients in American College of Surgeons National Surgical Quality Improvement Program are not at increased risk of 30-day postoperative complications following major urologic cancer surgery. These findings suggest that comorbidity burden, as opposed to race, is most strongly associated with the risk of postoperative complications. To minimize perioperative risk, clinicians should strive to preoperatively optimize medical comorbidities in all patients undergoing urologic cancer surgery.

The Need to Consider Longer-term Outcomes of Care: Racial/Ethnic Disparities Among Adult and Older Adult Emergency General Surgery Patients at 30, 90, and 180 Days

OBJECTIVES

Following calls from the National Institutes of Health and American College of Surgeons for "urgently needed" research, the objectives of the present study were to (1) ascertain whether differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among adult (18-64 yr) and older adult (≥65 yr) emergency general surgery (EGS) patients; (2) vary by diagnostic category; and (3) are explained by variations in insurance, income, teaching status, hospital EGS volume, and a hospital's proportion of minority patients.

BACKGROUND

Racial/ethnic disparities have been described in in-hospital and 30-day settings. How longer-term outcomes compare-a critical consideration for the lived experience of patients-has, however, only been limitedly considered.

METHODS

Survival analysis of 2007 to 2011 California State Inpatient Database using Cox proportional hazards models.

RESULTS

A total of 737,092 adults and 552,845 older adults were included. In both cohorts, significant differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions were found, pointing to persistently worse outcomes between non-Hispanic Black and White patients [180-d readmission hazard ratio (95% confidence interval):1.04 (1.03-1.06)] and paradoxically better outcomes among Hispanic adults [0.85 (0.84-0.86)] that were not encountered among Hispanic older adults [1.06 (1.04-1.07)]. Stratified results demonstrated robust morbidity and readmission trends between non-Hispanic Black and White patients for the majority of diagnostic categories, whereas variations in insurance/income/teaching status/EGS volume/proportion of minority patients all significantly altered the effect-combined accounting for up to 80% of risk-adjusted differences between racial/ethnic groups.

CONCLUSIONS

Racial/ethnic disparities exist in longer-term outcomes of EGS patients and are, in part, determined by differences in factors associated with emergency care. Efforts such as these are needed to understand the interplay of influences-both in-hospital and during the equally critical, postacute phase-that underlie disparities' occurrence among surgical patients.

Pipeline program recruits and retains women and underrepresented minorities in procedure based specialties: A brief report

As the US population continues to grow in racial and ethnic diversity, we also continue to see healthcare disparities across racial lines. Considerable attention has been given to creating a physician workforce that better reflects the population served by healthcare professionals. To address the low numbers of women and underrepresented minorities in procedural based specialties, Nth Dimensions has sought to address and eliminate healthcare disparities through strategic pipeline initiatives. This is a retrospective observational cohort study of 118 medical students from 29 accredited US medical schools, who were awarded a position in the Nth Dimensions Summer Internship program between 2005 and 2012. Overall, 84 NDSI scholars applied and 81 matched into procedure-based specialties; therefore the overall retention rate was 75% and the overall match rate across the eight cohorts was 72.3%. Through intervention-based change, the authors hypothesize that greater numbers in the residency training cohorts can lead to a greater number of physicians with diverse backgrounds and perspectives. Ultimately, this will enhance quality of care for all patients and improve decision making process that influence healthcare systems.

SUMMARY

Strategic pipeline programs increase successful recruit women and underrepresented minorities to apply and matriculate into procedure based residency programs. This is a retrospective observational cohort study of 118 medical students who completed the Nth Dimensions Summer Internship program between 2005 and 2012. Overall, 84 NDSI scholars applied and 81 matched into procedure-based specialties; therefore the overall retention rate was 75% and the overall match rate across the eight cohorts was 72.3%.

Role of in-hospital care quality in reducing anxiety and readmissions of kidney transplant recipients

BACKGROUND

A total of 17,000 patients receive kidney transplants each year in the United States. The 30-day readmission rate for kidney transplant recipients is over 30%. Our research focuses on the relationship between the quality of care delivered during the patient's hospital stay for a kidney transplant, and the patient health outcomes and readmissions related to the transplant.

METHODS

We interviewed 20 kidney transplant recipients at a major transplant center in the United States. Findings from these interviews were used to inform the data collection using structured surveys, which were administered to an additional 77 kidney transplant recipients. We used ordinary least squares regression to predict the effects of two dimensions of in-hospital care quality-information consistency and empathetic care delivery-on level of patient anxiety 1 week following discharge. Further, we estimated a logistic regression to predict the effect of anxiety, combined with the two dimensions of in-hospital care quality, on occurrence of 30-day readmissions.

RESULTS

Patient anxiety levels 1 wk after discharge are significantly associated with information consistency and empathetic delivery of care. Patient anxiety 1 wk after discharge is associated with occurrence of 30-d readmissions. The logistic regression model indicates that the risk of getting readmitted is 110% higher for a one unit increase in patient anxiety level 1 wk after discharge. Finally, patient anxiety fully mediates the effects of consistency of information and empathetic care delivery on occurrence of 30-d readmissions (50.96% of the effect is mediated).

CONCLUSIONS

Our study suggests two ways of preventing readmissions through reduction of postdischarge anxiety: (1) standardizing in-hospital care, so that information received by patients is consistent, and (2) by training caregivers to be more empathetic toward patients during the delivery of this information.

Awareness of racial/ethnic disparities in surgical outcomes and care: factors affecting acknowledgment and action

BACKGROUND

Studies have demonstrated racial/ethnic disparities in surgical outcomes and care. Surgeon awareness and its association with institutional action remain unclear. The study sought to assess surgeons' awareness of racial/ethnic disparities, ascertain whether demographic and practice factors influence acknowledgement of disparities, and determine whether surgeons are seeking to mitigate disparities.

METHODS

Anonymous online survey was administered to a random sample of American College of Surgeons (ACS) general surgeons (July 2013 to March 2014). Responses were weighted for nonresponse and risk-adjusted using logistic regression.

RESULTS

172 surgeons completed the survey. Levels of acknowledged disparities were low. Less than one half reported institutional efforts to address disparities, and less than one fourth had taken efforts to investigate disparities in their personal practice. Several respondent factors including Academic Medical Center affiliation, awareness of the ACS statement on optimal access, and year of medical school graduation significantly associated with expressed acknowledgment of disparities.

CONCLUSIONS

Such associations speak to the need for continued efforts to promote enhanced provider awareness and participation. As the field of surgical disparities moves from understanding to action, we must acknowledge the contributing role that providers play.
