Enhanced Recovery After Surgery Protocols May Help Reduce Racial and Socioeconomic Disparities in Cardiac Surgery

Racial and Ethnic Patient Care Disparities in Anesthesiology: History, Current State, and a Way Forward

Disparities in patient care and outcomes are well-documented in medicine but have received comparatively less attention in anesthesiology. Those disparities linked to racial and ethnic identity are pervasive, with compelling evidence in operative anesthesiology, obstetric anesthesiology, pain medicine, and critical care. This narrative review presents an overview of disparities in perioperative patient care that is grounded in historical context followed by potential solutions for mitigating disparities and inequities.

Multimodal Analgesic Effectiveness on Acute Postoperative Pain Management After Adult Cardiac Surgery: Protocol for a Systematic Review

BACKGROUND

Many patients report moderate to severe pain in the acute postoperative period. Enhanced recovery protocols recommend multimodal analgesics, but the optimal combination of these is unknown.

PURPOSE

The aim of this study was to synthesize the best available evidence about effectiveness of multimodal analgesics on pain after adult cardiac surgery.

METHODS

A systematic review to determine the effect of multimodal postoperative analgesics is proposed (International Prospective Register of Systematic Reviews Registration CRD42022355834). Multiple databases including the Cochrane Library, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, American Psychological Association, the Education Resources Information Centre, the Excerpta Medica database, the Medical Literature Analysis and Retrieval System Online, Scopus, Web of Science, and clinical trials databases will be searched. Screening in Covidence and quality assessment will be conducted by 2 authors. A grading of recommendations, assessment, development, and evaluation summary of findings will be presented if meta-analysis is possible.

Comparison of Enhanced Recovery After Surgery (ERAS) metrics by race among gynecologic oncology patients: Ensuring equitable outcomes

OBJECTIVES

Race and ethnicity are not routinely audited in Enhanced Recovery After Surgery (ERAS) pathways. Given known racial disparities in outcomes in gynecologic oncology, the purpose of this study was to compare differences in ERAS implementation and outcomes by race.

METHODS

A cohort study was performed among gynecologic oncology patients enrolled in an ERAS pathway at one academic institution from March 2017 to December 2021. Compliance with ERAS metrics, postoperative complications, 30-day survival, reoperations, intensive care unit (ICU) transfers, and readmissions within 30 days were compared by race.

RESULTS

Of 1083 patients (17.0% non-white), non-white women were younger (54.2 years ±13.1 vs. 60.7 years ±13.6, p < 0.001) and proportionally fewer spoke English (75.0% vs. 97.8%, p < 0.001). Fewer non-white women received preadmission ERAS education (73.4% vs. 79.9%, p = 0.05). There were no differences in ERAS implementation by race, including similar rates of preoperative nutritional assessment, carbohydrate loading, antibiotic and thrombosis prophylaxis, and unplanned surgeries by race. There were no differences in complications, reoperations, ICU transfers, or readmissions by race on univariate and multivariate analysis. Four non-white (2.2%) and two white women (0.2%, p = 0.009) died within 30 days of surgery.

CONCLUSIONS

Fewer non-white women received preadmission education, possibly due to language barriers. ERAS compliance, postoperative complications, readmissions, reoperations, and ICU transfers did not differ by race. There were two additional deaths within 30 days postoperatively among non-white women compared to white women - which is difficult to interpret given the rarity of perioperative mortality - but appeared unlikely to be related to differences in ERAS protocol implementation. ERAS programs should ensure educational materials are translated into various languages and audit metrics by race to ensure equitable outcomes.

The effect of socioeconomic factors on patient outcomes in cardiac surgery

OBJECTIVES

Healthcare delivery is heterogenous; the reasons for this are numerous and complex. Patient-specific factors including geography, income, insurance status, age, and gender have been shown to bias surgical outcomes. Utilizing a prospectively collected all-payer database, we aim to evaluate the influence of socioeconomic factors on mortality and length of stay (LOS) after common cardiac surgical procedures.

METHODS

We utilized the National Inpatient Sample, Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality for the year 2019. We included patients undergoing coronary artery bypass grafting (CABG), aortic valve replacement (AVR), transcatheter aortic valve replacement (TAVR), and combined AVR/CABG using the 10th revision of the International Classification of Diseases procedure codes. AVR and CABG were combined into a separate cohort as this was felt to represent a different pathology than isolated valvular or coronary arterial disease. Baseline demographics were summarized. Multivariable regression was performed within each procedure group to model the odds of in-hospital mortality and hospital LOS with age, sex, insurance, zip-code median household income, and location as predictors.

RESULTS

Baseline patient characteristics including gender, income, geography, and payer status were similar between CABG, AVR, and AVR/CABG. TAVR patients had a higher proportion of female sex and Medicare as the primary payer, with an overall greater age. Multivariable Cox proportional hazards regression found that higher income was strongly associated with decreased LOS following AVR and CABG, and moderately associated in TAVR and AVR/CABG. Private insurance was associated with a decreased LOS in patients undergoing CABG, AVR, TAVR, and AVR/CABG. Female sex and increased age were associated with increased odds of mortality in TAVR, CABG, and AVR/CABG. Private insurance was associated with a decreased odds of mortality in patients undergoing AVR.

CONCLUSIONS

These findings reveal significant disparities in patient outcomes after routine cardiac operations that are associated with socioeconomic status. Patients who did not have private insurance or had lower incomes were found to be at risk for increased LOS. Women were at a higher risk of mortality for several operations, a finding which has been previously described elsewhere. Private insurance conveyed a decreased odds of mortality in patients undergoing AVR. This data set serves to highlight differences in healthcare outcomes based on a variety of socioeconomic, geographic, and other inherent factors. Additional research is needed to identify the mechanisms behind these disparities with the goal of providing equitable care to all patients.

Towards Equitable Surgical Management of Inflammatory Bowel Disease: A Systematic Review of Disparities in Surgery for Inflammatory Bowel Disease

BACKGROUND

Existing evidence for disparities in inflammatory bowel disease is fragmented and heterogenous. Underlying mechanisms for differences in outcomes based on race and socioeconomic status remain undefined. We performed a systematic review of the literature to examine disparities in surgery for inflammatory bowel disease in the United States.

METHODS

Electronic databases were searched from 2000 through June 11, 2021, to identify studies addressing disparities in surgical treatment for adults with inflammatory bowel disease. Eligible English-language publications comparing the use or outcomes of surgery by racial/ethnic, socioeconomic, geographic, and/or institutional factors were included. Studies were grouped according to whether outcomes of surgery were reported or surgery itself was the relevant end point (utilization). Quality was assessed using the Newcastle-Ottawa Scale for observational studies.

RESULTS

Forty-five studies were included. Twenty-four reported surgical outcomes and 21addressed utilization. Race/ethnicity was considered in 96% of studies, socioeconomic status in 44%, geographic factors in 27%, and hospital/surgeon factors in 22%. Although study populations and end points were heterogeneous, Black and Hispanic patients were less likely to undergo abdominal surgery when hospitalized; they were more likely to have a complication when they did have surgery. Differences based on race were correlated with socioeconomic factors but frequently remained significant after adjustments for insurance and baseline health.

CONCLUSIONS

Surgical disparities based on sociologic and structural factors reflect unidentified differences in multidisciplinary disease management. A broad, multidimensional approach to disparities research with more granular and diverse data sources is needed to improve health care quality and equity for inflammatory bowel disease.

Enhanced Recovery After Cardiac Surgery: A Propensity-Matched Analysis

Enhanced Recovery After Surgery (ERAS) pathways have improved clinical outcomes, cost-effectiveness, and patient satisfaction across multiple non-cardiac surgical specialties. Since the adaptation of ERAS in cardiac surgery is rapidly increasing yet still evolving, herein, we demonstrate early results of our implementation of ERAS cardiac guidelines. We retrospectively reviewed all patients who were managed with our institutional ERAS Cardiac Surgery guidelines between 5/2018 and 6/2019(N = 102). Postoperative primary outcomes (total ventilation times(hours), intensive-care unit(ICU) stay, and postoperative hospital length of stay (LOS)) were compared to 1:1 propensity matched controls from the pre ERAS era between January 2017 and March 2019. A total of 76 propensity-matched pairs were identified. Compared to the matched controls, ERAS patients had significantly shorter median ventilation times(3.5 vs. 5.3 hours, p = .01), ICU stays(median 28 vs 48 hours, p=.005) and postoperative hospital LOS (median 5 vs. 6 days, p = .03). There were no operative mortalities and no significant differences in 30-day readmission rates. There were also no significant differences in post-operative stroke, acute kidney injury, atrial fibrillation, and reoperation rates for bleeding. Two-year survival was also not statistically different between the two cohorts (p = .22). Our initial experience with implementation of ERAS protocols in cardiac surgery appear to demonstrate that these protocols are associated with shorter ventilation times, ICU stay, and hospital LOS without compromising patient outcomes. While these results are promising yet preliminary, further studies are warranted to demonstrate whether ERAS algorithms in cardiac surgery can consistently expedite postoperative recovery and improve outcomes.

Racial disparities exist in surgical outcomes for patients with inflammatory bowel disease

BACKGROUND

Racial disparities in surgical outcomes exist for Black patients with IBD compared to White patients. However, previous studies fail to include other racial/ethnic populations. We hypothesized these disparities exist for Hispanic and Asian patients.

METHODS

This is a retrospective cohort study of patients undergoing surgery for IBD using the American College of Surgeons National Surgical Quality Improvement Program (ACS- NSQIP) database (2005-2017). Bivariate comparisons and adjusted multivariable regressions were performed to evaluate associations between race and outcomes.

RESULTS

Of 23,901 patients with IBD, the racial/ethnic makeup were: 88.7% White, 7.6% Black, 2.4% Hispanic and 1.4% Asian. Overall mean LOS was 8 days (SD 8.2) and significantly varied between groups (8d for White, 10d for Black, 8.5d for Hispanic, and 11.1d for Asian; p < 0.001). Hispanic patients had the highest odds of readmission (OR: 1.4; 95% CI 1.1-1.8). Black patients had increased odds of renal insufficiency (OR: 1.8; 95% CI 1.1-2.9), bleeding requiring transfusions (OR: 1.7; 95% CI 1.4-1.9), and sepsis (OR: 1.7; 95% CI 1.4-2.02) compared to White patients.

CONCLUSIONS

Racial disparities exist among IBD patients undergoing surgery. Black, Hispanic and Asian IBD patients experience major disparities in post-operative complications, readmissions and LOS, respectively, when compared to White patients with IBD. Future research is needed to better understand the mechanisms of these disparities including evaluation of social determinants of health.

Racial disparities in surgical outcomes of patients with Inflammatory Bowel Disease

BACKGROUND

Inflammatory Bowel Disease (IBD) has not historically been a focus of racial health disparities research. IBD has been increasing in the black community. We hypothesized that outcomes following surgery would be worse for black patients.

METHODS

A retrospective cohort study of death and serious morbidity (DSM) of patients undergoing surgery for IBD was performed using data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP 2011-2014). Multivariable logistic regression modeling was performed to evaluate associations between race and outcomes.

RESULTS

Among 14,679 IBD patients, the overall rate of DSM was 20.3% (white: 19.3%, black 27.0%, other 23.8%, p < 0.001). After adjustment, black patients remained at increased risk of DSM compared white patients (OR: 1.37; 95% CI 1.14-1.64).

CONCLUSIONS

Black patients are at increased risk of post-operative DSM following surgery for IBD. The elevated rates of DSM are not explained by traditional risk factors like obesity, ASA class, emergent surgery, or stoma creation.
