Racial Disparities in Pediatric Anesthesia

Racial and ethnic disparities in regional anesthesia in the United States: A narrative review

BACKGROUND

Racial and ethnic disparities exist in the delivery of regional anesthesia in the United States. Anesthesiologists have ethical and economic obligations to address existing disparities in regional anesthesia care.

OBJECTIVES

Current evidence of racial and ethnic disparities in regional anesthesia utilization in adult patients in the United States is presented. Potential contributors and solutions to racial disparities are also discussed.

EVIDENCE REVIEW

Literature search was performed for studies examining racial and ethnic disparities in utilization of regional anesthesia, including neuraxial anesthesia and/or peripheral nerve blocks.

FINDINGS

While minoritized patients are generally less likely to receive regional anesthesia than white patients, the pattern of disparities for different racial/ethnic groups and for types of regional anesthetics can be complex and varied. Contributors to racial/ethnic disparities in regional anesthesia span hospital, provider, and patient-level factors. Potential solutions include standardization of regional anesthetic practices via Enhanced Recovery After Surgery (ERAS) pathways, increasing patient education, health literacy, language translation services, and improving diversity and cultural competency in the anesthesiology workforce.

CONCLUSION

Racial and ethnic disparities in regional anesthesia exist. Contributors and solutions to these disparities are multifaceted. Much work remains within the subspecialty of regional anesthesia to identify and address such disparities.

Racial bias in pediatric pain perception

Racial disparities in pediatric pain care are prevalent across a variety of healthcare settings, and likely contribute to broader disparities in health, morbidity, and mortality. The present research expands on prior work demonstrating potential perceptual contributions to pain care disparities in adults and tests whether racial bias in pain perception extends to child targets. We examined the perception and hypothetical treatment of pain in Black and White boys (Experiment 1), Black and White boys and girls (Experiment 2), Black and White boys and adult men (Experiment 3), and Black, White, Asian, and Latinx boys (Experiment 4). Across this work, pain was less readily perceived on Black (versus White) boys' faces-though this bias was not observed within girls. Moreover, this perceptual bias was comparable in magnitude to the same bias measured with adult targets and consistently predicted bias in hypothetical treatment. Notably, bias was not limited to Black targets-pain on Hispanic/Latinx boys' faces was also relatively underperceived. Taken together, these results offer strong evidence for racial bias in pediatric pain perception. PERSPECTIVE: This article demonstrates perceptual contributions to racial bias in pediatric pain recognition. Participants consistently saw pain less readily on Black boys' faces, compared to White boys, and this perceptual bias consistently predicted race-based gaps in treatment. This work reveals a novel factor that may support pediatric pain care disparities.

Differential Utilization of Parental Presence and Premedication for Induction of Anesthesia in Pediatric Patients

PURPOSE

Known disparities exist in pain treatment between African American, Latino, and White children. A recent study described 'adultification' of Black children, with Black children being less likely to have a parent present at induction of anesthesia and less likely to receive an anxiolytic premedication before proceeding to the operating room. The aim of this study is to identify differences based on race and socioeconomic status when treating children and their families for anesthetic induction. We hypothesize that differences exist such that certain populations are less likely to receive sedative premedication and less likely to have parents present at induction of anesthesia.

DESIGN

This was a retrospective cohort study.

METHODS

Demographic data were obtained along with type of surgical procedure, type of anesthesia induction, use of premedication, and involvement of child life services (including the plan for parental presence at induction) for all pediatric patients presenting for anesthetics from February 2019 to March 2020. Statistical analysis consisted of fitting logistic mixed effects models for caregiver presence or for midazolam use during induction, with fixed effects for sex, race, ethnicity, language, public/private insurance, and anesthetic risk, and with the provider as a random effect.

FINDINGS

A total of 7,753 patients were included in our statistical analyses, and parental presence focused on 4,102 patients with documentation from child life specialists. Females were less likely than males to have parents present at induction (odds ratio [OR] 0.77, confidence interval [CI] [0.67, 0.89]). When looking at race, American Indian/Alaskan Native patients (OR 0.23 [CI 0.093, 0.47]) and Black/African American patients OR 0.64 [CI 0.47, 0.89]) were less likely to have a parent present induction than White patients. Patients with private insurance were more likely to have parents present than patients with public insurance (OR 0.63 CI [0.5, 0.78]). These findings held true in age-separated sensitivity analysis. Asian patients were less likely to receive midazolam premedication (OR 0.65 CI [0.49, 0.86]).

CONCLUSIONS

This study supports previous work showing differential use of parental presence at induction based on race. Additionally, it also shows different treatment based on sex and public insurance status, a surrogate for socioeconomic status.

Racial and Ethnic Disparities in Pediatric Musculoskeletal Care

PURPOSE OF REVIEW

This article provides a review of recent published research studying racial, ethnic, and socioeconomic disparities in pediatric musculoskeletal care.

RECENT FINDINGS

Disparities in pediatric musculoskeletal care are demonstrated in two general realms: access to care and health outcomes. Though initiatives have been proposed or enacted to address disparities, underrepresented minorities and patients from lower socioeconomic statuses continue to face barriers across the spectrum of orthopedic care and poorer ultimate outcomes after both non-operative and operative management. Minority pediatric patients and those from lower socioeconomic statuses experience delays across the spectrum of orthopedic care for both urgent and non-urgent conditions. They wait longer between injury date and initial orthopedic evaluation, longer to receipt of diagnostic imaging, and longer to ultimate treatment than their counterparts. When finally able to obtain musculoskeletal care and treatment, they are at higher risk of poor in-hospital outcomes and inpatient complications, worse patient reported outcomes, and suboptimal pain management. In the outpatient setting, they receive less physical therapy and follow-up clinic visits, resulting in greater stiffness and strength deficits, and are ultimately less likely to meet return to sport criteria.

Racial Inequity in Pediatric Anesthesia

Purpose of Review

Minority health disparities have received renewed attention in the USA following several highly publicized racial injustices in 2020. Though the focus has been largely on adults, children are not immune to these inequities. By reviewing racial disparities in pediatric perioperative care, we aim to engage the anesthesia community in the fight against systemic racism.

Recent Findings

Minority children have higher rates of anesthetic and surgical morbidity compared to White children, including respiratory events, length of stay, hospital costs, and even death. These inequities occur across surgical specialties and environments.

Summary

Racial disparities in the perioperative health and management of children are ubiquitous. Herein, we will summarize recent pediatric health disparity literature, discuss some important contributors to persistent inequities, and propose avenues for anesthesiologists to impact the pursuit of equitable healthcare outcomes.

Diversity, equity, and inclusion within the Society for Pediatric Anesthesia: A mixed methods assessment

BACKGROUND

Leadership of the Society for Pediatric Anesthesia created the Diversity, Equity, and Inclusion committee in 2018 to prioritize diversity work. The Society for Pediatric Anesthesia-Diversity, Equity, and Inclusion committee implemented a baseline survey of the Society for Pediatric Anesthesia membership in 2020 to assess demographics, equity in leadership, inclusivity, and attitudes toward diversity work. The Society for Pediatric Anesthesia plays a significant role in shaping the future of pediatric anesthesiology and in supporting our diverse pediatric patients.

METHODS

This study is an IRB-exempt, cross-sectional survey of the Society for Pediatric Anesthesia membership. Quantitative analysis provided descriptive statistics of demographics, practice characteristics, and involvement within the Society for Pediatric Anesthesia. Qualitative thematic analysis provided an in-depth assessment of perceptions of diversity, challenges faced, and prioritization of Diversity, Equity, and Inclusion efforts within the Society for Pediatric Anesthesia.

RESULTS

Out of 3 242 Society for Pediatric Anesthesia members, 1 232 completed the survey representing 38% of overall membership. Respondents were 89.2% United States members, 52.7% female, 55.7% non-Hispanic White, 88.6% heterosexual, 95.7% non-military, 59.2% religious, and 2.1% have an Americans with Disabilities Act recognized disability. All major United States geographical areas were represented equally with 71% practicing in urban areas and 67% in academic settings. Ethnic/racial minorities were more likely to be international medical graduates (p < .001). Among United States members, 41.5% report being fluent in a language other than English, and 23.5% of those fluent in another language are certified to interpret. Compared to men, women are less likely to be in leadership roles (p < .003), but we found no difference in participation and leadership when stratified by race/ethnicity, geography, international medical graduate status, or sexuality. Racial/ethnic minorities (p < .028), women (p < .001), and lesbian, gay, bisexual, transgender, and queer members (p < .044) more frequently hold lower academic rank positions when compared to white, heterosexual, and male members. Half of respondents were unsure whether diversity, equity, and inclusion challenges existed within the Society for Pediatric Anesthesia while the other half demonstrated opposing views. Among those who reported diversity, equity, and inclusion challenges, the themes centered around persistent marginalization, the need for more inclusive policies and increased psychological safety, and lack of leadership diversity.

CONCLUSIONS

Compared to the diversity of the pediatric population we serve, there are still significant gaps in demographic representation within the Society for Pediatric Anesthesia. As well, there is no consensus among Society for Pediatric Anesthesia membership regarding perceptions of diversity, equity, and inclusion in pediatric anesthesia in the United States. Among those who reported diversity challenges, opportunities for the Society for Pediatric Anesthesia and Anesthesiology Departments to better support minoritized members included bolstering workforce diversity efforts and awareness via more inclusive policies, improved psychological safety, and increasing diversity in leadership. If pediatric anesthesiology is like other specialties, gaining consensus and improving diversity in the workforce might advance pediatric anesthesia innovation, quality, and safety for children of all backgrounds in the United States.

Trends of Racial/Ethnic Disparities in Pediatric Central Line-Associated Bloodstream Infections

BACKGROUND AND OBJECTIVES

Central line-associated bloodstream infections (CLABSIs), eminently preventable nosocomial infections, are a substantial source of morbidity, mortality, and increased resource utilization in pediatric care. Racial or ethnic disparities in health outcomes have been demonstrated across an array of medical specialties and practices in pediatric patients. However, it is unknown whether disparities exist in the rate of CLABSIs. Our objective was to evaluate the trends in racial and ethnic disparities of CLABSIs over the past 5 years.

METHODS

This is a retrospective cohort study using data from Pediatric Health Information System database collected from tertiary children's hospitals in the United States. Participants included 226 802 children (<18 years) admitted to the emergency department or inpatient ward between 2016 and 2021 who required central venous catheter placement. The primary outcome was risk-adjusted rate of CLABSI, occurring during the same admission, across race and ethnicity.

RESULTS

Of the 226 802 children, 121 156 (53.4%) were White, 40 589 (17.9%) were Black, and 43 374 (19.1%) were Hispanic. CLABSI rate decreased in all racial/ethnic groups over the study period, with the rates being consistently higher in Black (relative risk [RR], 1.27; 95% confidence interval [CI], 1.17-1.37; P < .01) and Hispanic children (RR, 1.16; 95% CI, 1.08-1.26; P < .01) than in White children. There was no statistically significant evidence that gaps in CLABSI rate between racial/ethnic groups narrowed over time.

CONCLUSIONS

CLABSI rate was persistently higher among Black and Hispanic children than their White peers. These findings emphasize the need for future exploration of the causes of persistent racial and ethnic disparities in pediatric patients.

Racial Disparities in Postoperative Outcomes Following Operative Management of Pediatric Developmental Dysplasia of the Hip

BACKGROUND

Developmental dysplasia of the hip in pediatric patients can be managed conservatively or operatively. Understanding patient risk factors is important to optimize outcomes following surgical treatment of developmental dysplasia of the hip. Racial disparities in procedural outcomes have been studied, however, there is scarce literature on an association between race and complications following pediatric orthopaedic surgery. Our study aimed to determine the association between pediatric patients' race and outcomes following operative management of hip dysplasia by investigating 30-day postoperative complications and length of hospital stay.

METHODS

The National Surgical Quality Improvement Program-Pediatric database was utilized from the years 2012 to 2019 to identify all pediatric patients undergoing surgical treatment for hip dysplasia. Patients were stratified into 2 groups: patients who were White and patients from underrepresented minority (URM) groups. URM groups included those who were Black or African American, Hispanic, Native American or Alaskan, and Native Hawaiian or Pacific Islander. Differences in patient demographics, comorbidities, and postoperative outcomes were compared between the 2 cohorts using bivariate and multivariate analyses.

RESULTS

Of the 9159 pediatric patients who underwent surgical treatment for hip dysplasia between 2012 and 2019, 6057 patients (66.1%) were White and 3102 (33.9%) were from URM groups. In the bivariate analysis, compared with White patients, patients from URM groups were more likely to experience deep wound dehiscence, pneumonia, unplanned reintubation, cardiac arrest, and extended length of hospital stay. Following multivariate analysis, patients from URM groups had an increased risk of unplanned reintubation (odds ratio: 3.583; P=0.018).

CONCLUSIONS

Understanding which patient factors impact surgical outcomes allows health care teams to be more aware of at-risk patient groups. Our study found that pediatric patients from URM groups who underwent surgery for correction of hip dysplasia had greater odds of unplanned reintubation when compared with patients who were White. Further research should investigate the relationship between multiple variables including race, low socioeconomic status, and language barriers on surgical outcomes following pediatric orthopaedic procedures.

LEVEL OF EVIDENCE

Level III-retrospective cohort analysis.

Association between implementation of a coordinated care pathway in idiopathic scoliosis patients and a reduction in perioperative outcome disparities

BACKGROUND

There are well-documented racial and ethnic disparities in treatment and perioperative outcomes for patients with adolescent idiopathic scoliosis.

AIMS

We hypothesize that the implementation of a coordinated care pathway for pediatric patients undergoing posterior spinal fusion for adolescent idiopathic scoliosis may be associated with a reduction in racial and ethnic disparities in perioperative outcomes.

METHODS

This is a retrospective pre- and post-test cohort study of patients who underwent posterior spinal fusion for adolescent idiopathic scoliosis at our institution between July 1, 2013 and August 5, 2019. We implemented a coordinated care pathway in March 2015. Patient demographics included age, race, ethnicity, weight, gender, insurance status, ASA class, time between the date surgery was ordered and the date surgery occurred, degree of scoliosis, and the number of spinal levels fused. The primary outcome was length of stay. The secondary outcomes included transfusion rates, pain scores, and postoperative complications. Multivariable regression models compared outcome medians across race/ethnicity. Disparities were defined as the difference in adjusted outcomes by race/ethnicity.

RESULTS

Four hundred twenty-four patients underwent posterior spinal fusion for adolescent idiopathic scoliosis at our institution (116 prepathway and 308 postpathway). The median length of stay of Black patients was 1.0 day (95% CI: 0.4, 1.5; p = .006) longer than White patients prepathway. Prepathway patients who self-identified as Other had a 1.2 (95% CI: 0.5, 1.9; p = .004) higher median average pain score on postoperative day 1 compared with White patients. On postoperative day 2, patients who identified as Other had 2.0 (95% CI: 0.8, 3.2; p = .005) higher pain score compared with White patients prepathway. Postpathway, there were no significant differences in outcomes by race/ethnicity.

CONCLUSIONS

Our study supports the hypothesis that use of a coordinated care pathway is associated with a reduction in racial and ethnic disparities in length of stay and pain scores in pediatric patients undergoing posterior spinal fusion.

Association of Race and Family Socioeconomic Status With Pediatric Postoperative Mortality

IMPORTANCE

Racial disparities in postoperative outcomes have remained difficult to eliminate. It is commonly understood that socioeconomic status (SES) is an important factor associated with excess risk of postoperative morbidity and death. To date, comparable data exploring the association of family SES with pediatric postoperative mortality are unavailable, and it is unknown whether the advantage provided by higher income status is equitable across racial groups.

OBJECTIVE

To assess whether increasing family SES is associated with lower pediatric postoperative mortality and, if so, whether this association is equitable among Black and White children.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study used data from 51 freestanding pediatric tertiary care hospitals across the US that reported to the Children's Hospital Association Pediatric Health Information System. The study included 1 378 111 Black and White children younger than 18 years who underwent inpatient surgical procedures between January 1, 2004, and December 31, 2020.

EXPOSURES

The exposures of interest were race (Black and White) and parental income quartile (used as a proxy for SES and measured by median income quartile of the zip code of residence). Race was self-reported by parents or guardians at admission or assessed by the registration team consistent with each hospital's policy and state legislation.

MAIN OUTCOMES AND MEASURES

The primary outcome was risk-adjusted in-hospital mortality rates by race and parental income quartile controlled for baseline covariates. To evaluate whether belonging to the highest income quartile modified the association between race and postoperative mortality, multiplicative and additive interactions were examined.

RESULTS

Among 1 378 111 children (773 364 [56.1%] male; mean [SD] age, 7 [6] years) who received inpatient surgical procedures during the study period, 248 464 children (18.0%) were Black, and 1 129 647 children (82.0%) were White; 211 127 children (15.3%) were Hispanic, and 825 477 (59.9%) were non-Hispanic. Only 49 541 Black children (20.3%) belonged to the highest income quartile compared with 482 758 White children (43.0%). The overall mortality rate was 1.2%, and mortality rates decreased as income quartile increased (1.4% in quartile 1 [lowest income], 1.3% in quartile 2, 1.0% in quartile 3, and 0.9% in quartile 4 [highest income]; P < .001). Among those belonging to the 3 lowest income quartiles, Black children had 33% higher odds of postoperative death compared with White children (adjusted odds ratio, 1.33; 95% CI, 1.27-1.39; P < .001). This racial disparity gap persisted among children belonging to the highest income quartile (adjusted odds ratio, 1.39; 95% CI, 1.25-1.54; P < .001). Postoperative mortality rates among Black children in the highest income quartile (1.30%; 95% CI, 1.19%-1.42%) were comparable to those of White children in the lowest income quartile (1.20%; 95% CI, 1.16%-1.25%). The interaction between Black race and income was not statistically significant on either the multiplicative scale (β for interaction = 1.04; 95% CI, 0.93-1.17; P = .45) or the additive scale (relative excess risk due to interaction = 0.01; 95% CI, -0.11 to 0.11; P > .99), suggesting no reduction in the disparity gap across increasing income levels.

CONCLUSIONS AND RELEVANCE

In this cohort study, increasing SES was associated with lower pediatric postoperative mortality. However, postoperative mortality rates were significantly higher among Black children in the highest SES category compared with White children in the same category, and mortality rates among Black children in the highest SES category were comparable to those of White children in the lowest SES category. These findings suggest that increasing family SES did not provide equitable advantage to Black compared with White children, and interventions that target socioeconomic inequities alone may not fully address persistent racial disparities in pediatric postoperative mortality.

Identification of the risk factors in perioperative respiratory adverse events in children under general anesthesia and the development of a predictive model

BACKGROUND

This study explored the risk factors of perioperative respiratory adverse events in children under 12 years old undergoing general anesthesia surgery. A prediction model was constructed according to the related risk factors to provide a basis for timely clinical intervention and decision-making.

METHODS

Children under 12 years old who underwent general anesthesia in our hospital between January 2016 and December 2020 were included in this study. The clinical data, including age, gender, weight, American Society of Anesthesiologists (ASA) grade classification, operation season, preoperative hospital stay, anesthesia time, and postoperative pain score, were collated. Continuous variables were converted to categorical variables. Logistic regression analysis was used to screen independent risk factors and a nomogram was constructed to predict the probability of adverse events. Fitting curves and receiver operating characteristic (ROC) curves were utilized to verify the model.

RESULTS

Logistic regression analyses demonstrated that age [odds ratio (OR) =1.32, 95% confidence interval (CI): 1.08 to 1.49], body weight (OR =1.49, 95% CI: 1.21 to 1.84), anesthesia time (OR =1.61, 95% CI: 1.32 to 1.78), and surgery season (OR =1.12, 95% CI: 1.07 to 1.39) were independent risk factors for respiratory adverse events in children undergoing general anesthesia (P<0.05). The risk of respiratory-related adverse events increased in children with grade II ASA classification compared to children with grade I ASA classification (P<0.05). Similarly, the risk of respiratory adverse events increased in children with level III pain scores compared to children with level I pain scores (P<0.05). The calibration curve showed that the predicted curve was consistent with the actual curve. The area under the ROC curve (AUC) was 0.707, indicating that model showed great predictive ability.

CONCLUSIONS

Age, weight, anesthesia time, operation season, ASA grade, and pain score were identified as independent risk factors for respiratory adverse events in children undergoing general anesthesia. Using the above risk factors, a nomogram was established to predict the risk of respiratory system-related adverse events. The predicted results were highly consistent with the actual risk, and the false positive rate was within a reasonable range.

Racial and Ethnic Health Services Disparities in Pediatric Anesthesia Practice: A Scoping Review

Racial and ethnic disparities in pediatric anesthesia health services could result in minority children being at increased risk of poor outcomes, such as pain, anxiety, or over-exposure to medications. Yet, a comprehensive understanding of the literature on such disparities does not exist to date. The objective of this study is to describe health services disparities in pediatric anesthetic care in the pre-, intra-, or post-operative period by synthesizing current literature. We searched the National Library of Medicine's PubMed/Medline, Embase, and Web of Science for articles published between January 1, 2007, and May 9, 2020, to identify literature on racial and ethnic health services disparities in pediatric anesthesia. We used the Institute of Medicine's definition of disparities. Health services were related to pre-, intra-, or post-operative anesthetic care of pediatric patients (< 18 years old). Out of 2110 studies, 10 studies met the criteria for inclusion. Nine out of the ten articles were single-institutional observational studies, based at tertiary hospitals. Sample sizes ranged from 74 to 37,618 discrete participants, for a total of 69,350 subjects across all studies. Results of these studies present low-quality evidence and heterogeneous conclusions regarding pediatric anesthesia health services disparities. This review demonstrates the paucity and diversity of research on racial and ethnic disparities in pediatric anesthesia health services and suggests how future work might utilize improved data and rigorous study designs.
