Race, Ethnicity, and Pediatric Postsurgical Mortality: Current Trends and Future Projections.

BACKGROUND: No study has contextualized the aggregate human costs attributable to disparities in pediatric postsurgical mortalities in the United States, a critical step needed to convey the scale of racial inequalities to clinicians, policymakers, and the public. METHODS: We conducted a population-based study of 673 677 children from US hospitals undergoing intermediate to high-risk surgery between 2000 and 2019. We estimated the excess deaths that could be avoided if Black and Hispanic children had comparable mortality rates to white children. We estimated the mortality reduction required to eliminate disparities within the next decade. We finally evaluated the impact of policy changes targeting a modest annual 2.5% reduction in disparity-attributable mortality. RESULTS: During 2000 to 2019, risk-adjusted postoperative mortality trended consistently higher for both Black (adjusted RR [aRR]: 1.42, 95% confidence interval [CI]: 1.36-1.49) and Hispanic children (aRR: 1.22, 95% CI: 1.17-1.27) than for white children. These disparity gaps were driven by higher mortality in Black and Hispanic children receiving surgery in nonteaching hospitals (Black versus white aRR: 1.63, 95% CI: 1.38-1.93; Hispanic versus white aRR: 1.50, 95% CI: 1.33-1.70). There were 4700 excess deaths among Black children and 5500 among Hispanic children, representing. 10 200 (average: 536 per year) excess deaths among minoritized children. Policy changes achieving an annual 2.5% reduction in postoperative mortality would prevent approximately 1100 deaths among Black children in the next decade. CONCLUSIONS: By exploring the solution, and not just the problem, our study provides a framework to reduce disparities in pediatric postoperative mortality over the next decade.

Trends in Adolescent Comorbid Cannabis Use Disorder and Postoperative Complications.

BACKGROUND: Increasing legalization and widespread misinformation about the dangers of cannabis use have contributed to the rising prevalence of cannabis use disorder (CUD) among adolescents. Our objective was to determine the prevalence of CUD in adolescent surgical patients and evaluate its association with postoperative complications. METHODS: We performed a retrospective, 1:1 propensity-matched cohort study of adolescents (aged 10-17 years) with and without CUD who underwent inpatient operations at US hospitals participating in the Pediatric Health Information System from 2009 to 2022. The primary outcome was the trend in prevalence of CUD. Secondary outcomes included postoperative complications. Using a Bonferroni correction, we considered a P value < .008 to be significant. RESULTS: Of 558 721 adolescents undergoing inpatient surgery from 2009 to 2022, 2604 (0.5%) were diagnosed with CUD (2483 were propensity matched). The prevalence of CUD increased from 0.4% in 2009 to 0.6% in 2022 (P < .001). The adjusted odds of respiratory complications, ICU admission, mechanical ventilation, and extended hospital stay were significantly higher in adolescents with CUD (respiratory complications: odds ratio [OR], 1.52; 95% confidence interval [CI], 1.16-2.00; P = .002; ICU admission: OR, 1.78; 95% CI, 1.61-1.98; P < .001; mechanical ventilation: OR, 2.41; 95% CI, 2.10-2.77; P < .001; extended hospital stay: OR, 1.96; 95% CI, 1.74-2.20; P < .001). The propensity score-adjusted odds of postoperative mortality or stroke for adolescents with CUD were not significantly increased (mortality: OR, 1.40; 95% CI, 0.87-2.25; P = .168; stroke: OR, 2.46; 95% CI, 1.13-5.36; P = .024). CONCLUSIONS: CUD is increasing among adolescents scheduled for surgery. Given its association with postoperative complications, it is crucial to screen adolescents for cannabis use to allow timely counseling and perioperative risk mitigation.

Association of Neighborhood Opportunity, Race and Ethnicity with Pediatric Day-of-Surgery Cancellations: a Cohort Study.

BACKGROUND: Day-of-surgery cancellations impede healthcare access and contribute to inequities in pediatric healthcare. Socially disadvantaged families have many risk factors for surgical cancellation, including low health literacy, transportation barriers, and childcare constraints. These social determinants of health are captured by the Childhood Opportunity Index (COI) 2.0, a national quantification of neighborhood-level characteristics that contribute to a child's vulnerability to adversity. We studied the association of neighborhood opportunity with pediatric day-of-surgery cancellations. METHODS: We conducted a retrospective cohort study of children younger than 18 years of age scheduled for ambulatory surgery at a tertiary pediatric hospital between 2017 and 2022. We geocoded the primary address to determine COI 2.0 neighborhood opportunity. We used log-binomial regression to estimate the relative risk of day-of-surgery cancellation comparing different levels of neighborhood opportunity. We also estimated the relative risk of cancellations associated with race and ethnicity, by neighborhood opportunity. RESULTS: Overall, the incidence of day-of-surgery cancellation was 3.8%. The incidence of cancellation was lowest in children residing in very high opportunity neighborhoods and highest in children residing in very low opportunity neighborhoods (2.4% vs 5.7%, p<0.001). The adjusted relative risk of day-of-surgery cancellation in very low opportunity neighborhoods compared to very high opportunity neighborhoods was 2.24 (95%CI: 2.05-2.44, p<0.001). We found statistical evidence of an interaction of COI with race and ethnicity. In very low opportunity neighborhoods, Black children had 1.48 times greater risk of day-of-surgery cancellation than White children (95%CI: 1.35-1.63, p<0.001). Likewise, in very high opportunity neighborhoods, Black children had 2.17 times greater risk of cancellation (95%CI: 1.75-2.69, p<0.001). CONCLUSION: We found a strong relationship between pediatric day-of-surgery cancellation and neighborhood opportunity. Black children at every level of opportunity had the highest risk of cancellation, suggesting that there are additional factors that render them more vulnerable to neighborhood disadvantage.

Economic Impact of COVID-19 on a Free-Standing Pediatric Ambulatory Center.

Background: Operating safely throughout the coronavirus disease 2019 (COVID-19) pandemic has required surgical centers to adapt and raise their level of readiness. Intuitively, additional expenses related to such adaptation may have resulted in an increase in the cost of surgical care. However, little is known about the magnitude of such an increase, and no study has evaluated the temporal variation in the costs of care throughout the pandemic. The aim of the current study was to evaluate the impact of COVID-19 on the cost of surgical and anesthetic care in a free-standing, pediatric ambulatory care center. Methods: We performed a retrospective review of the electronic medical record (EMR) and financial data for pediatric ambulatory settings between 2019 and 2020 (April - August) from our tertiary care children's hospital. The primary outcomes were the inflation-adjusted surgical cost for elective tonsillectomy, adenoidectomy, and tympanostomy tubes (BTI) placement procedures in children less than 18 years of age. These data were obtained from financial databases and aggregated into categories including anesthesia services, operating room services, recovery room services, and supply and medical devices. Results: Costs per case to provide care were significantly higher following the COVID-19 pandemic in 2020 compared to 2019 across all services: anesthesia ($1,268 versus $1,143; cost ratio (CR): 1.11, 95% confidence interval (CI): 1.08 - 1.14, P-value < 0.001), operating room ($1,221 vs. $1,255; CR: 1.03, 95% CI: 1.02 - 1.04, P-value < 0.001), recovery room ($659 vs. $751; CR: 1.14, 95% CI: 1.10 - 1.18, P-value < 0.001), and supply ($150 vs. $271; CR: 1.81, 95% CI: 1.26 - 2.6, P-value = 0.001). There was an overall increase in healthcare service costs in 2020, with significant fluctuations in the early and mid-year months. Conclusion: Our study identified specific economic impacts of COVID-19 on free-standing pediatric ambulatory centers, thereby highlighting the need for innovative practices with cost containment for sustainability of such specialized centers when dealing with future pandemics related to COVID-19 or other viral pathogens.

Metabolomic profiling of pediatric post-tonsillectomy pain: A proof-of-concept study.

INTRODUCTION: Tonsillectomies are among the most common surgical procedures in children, with over 500 000 cases annually in the United States. Despite universal administration of intraoperative opioid analgesia, three out of five children undergoing tonsillectomy report moderate-to-severe pain upon recovering from anesthesia. The underlying molecular mechanisms of post-tonsillectomy pain are not well understood, limiting the development of targeted treatment strategies. Our study aimed to identify candidate serum metabolites associated with varying severity of post-tonsillectomy pain. METHODS: Venous blood samples and pain scores were obtained from 34 children undergoing tonsillectomy ± adenoidectomy, and metabolomic analysis was performed. Supervised orthogonal projections to latent structures discriminant analysis were employed to identify differentially expressed metabolites between children with severe and mild pain, as well as between moderate and mild pain. RESULTS: Pain scores differentiated children as mild (n = 6), moderate (n = 14), or severe (n = 14). Four metabolites (fatty acid 18:0(OH), thyroxine, phosphatidylcholine 38:5, and branched fatty acids C27H54O3) were identified as candidate biomarkers that differentiated severe vs. mild post-tonsillectomy pain, the combination of which yielded an AUC of 0.91. Similarly, four metabolites (sebacic acid, dicarboxylic acids C18H34O4, hydroxy fatty acids C18H34O3, and myristoleic acid) were identified as candidate biomarkers that differentiated moderate vs. mild post-tonsillectomy pain, with AUC values ranging from 0.85 to 0.95. CONCLUSION: This study identified novel candidate biomarker panels that effectively differentiated varying severity of post-tonsillectomy pain. Further research is needed to validate these data and to explore their clinical implications for personalized pain management in children undergoing painful surgeries.

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.
