Surgical Mortality and Race as a Risk Factor: A Compass, Not a Destination

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.

Racial Disparities in Surgery for Malignant Bowel Obstruction

BACKGROUND

Operative management of patients with malignant bowel obstruction (MBO) may provide effective palliation, but is associated with substantial risks. This study aimed to analyze racial and ethnic differences in surgical outcomes for patients with MBO.

METHODS

This retrospective study, using National Surgical Quality Improvement Program (NSQIP) registry data from 2010 to 2019, compared differences in outcomes by race and ethnicity for 2762 patients undergoing surgery for MBO. Multivariable logistic regression controlled for relevant covariates.

RESULTS

Black patients (n = 407) had higher rates of preoperative comorbidity and were more likely than White patients (n = 2081) to have major complications (28.5% vs 21.8%; p = 0.0031), overall complications (47.4% vs 40.4%; p = 0.0087), a longer median hospital stay (12 days; interquartile range [IQR, 8-19 days] vs 10 days [IQR, 7-17 days]; p = 0.0007), and unplanned readmission (17.1% vs 12.9%; p = 0.0266). Black patients had a similar mortality rate to that of White patients and were less frequently discharged to home (67.6% vs 73.0%; p = 0.0315). Differences in morbidity between Black patients and White patients persisted after controlling for potentially confounding variables. Hispanic patients had lower mortality than White patients (6.3% vs 13.1%; p = 0.0130) and a longer hospital stay (12 days [IQR, 8-18 days] vs 10 days [IQR, 7-17 days]; p = 0.0313). Outcomes did not differ between Asian patients and White patients.

CONCLUSIONS

This study demonstrated significant disparities for Black patients undergoing surgery for MBO. Understanding and addressing what drives these differences, including systemic inequalities such as access to care and racial biases, is essential to the achievement of more equitable, higher-quality patient care.

Economic Trends of Racial Disparities in Pediatric Postappendectomy Complications

BACKGROUND

Despite unparalleled advances in perioperative medicine, surgical outcomes remain poor for racial minority patients relative to their white counterparts. Little is known about the excess costs to the health care system related to these disparities.

METHODS

We performed a retrospective analysis of data from the Nationwide Inpatient Sample between 2001 and 2018. We included children younger than 18 years admitted with appendicitis who underwent an appendectomy during their hospital stay. We examined the inflation-adjusted hospital costs attributable to the racial disparities in surgical complications and perforation status, focusing on differences between non-Hispanic white patients and non-Hispanic Black patients.

RESULTS

We included 100 639 children who underwent appendectomy, of whom 89.9% were non-Hispanic white and 10.1% were non-Hispanic Black. Irrespective of perforation status at presentation, surgical complications were consistently higher for Black compared with white children, with no evidence of narrowing of the racial disparity gap over time. Black children consistently incurred higher hospital costs (median difference: $629 [95% confidence interval: $500-$758; P < .01). The total inflation-adjusted hospital costs for Black children were $518 658 984, and $59 372 044 (11.41%) represented the excess because of the racial disparities in perforation rates.

CONCLUSIONS

Although all patients had a progressive decline in post appendectomy complications, Black children consistently had higher rates of complications and perforation, imposing a significant economic burden. We provide an empirical economic argument for sustained efforts to reduce racial disparities in pediatric surgical outcomes, notwithstanding that eliminating these disparities is simply the right thing to do.
