Evaluating the complex association between Social Vulnerability Index and trauma mortality

Understanding the Impact of Enhanced Recovery Programs on Social Vulnerability, Race, and Colorectal Surgery Outcomes

BACKGROUND

Increasing social vulnerability, measured by the Social Vulnerability Index, has been associated with worse surgical outcomes. However, less is known about the impact of social vulnerability on patients who underwent colorectal surgery under enhanced recovery programs.

OBJECTIVE

We hypothesized that increasing social vulnerability is associated with worse outcomes before enhanced recovery implementation, but that after implementation, disparities in outcomes would be reduced.

DESIGN

Retrospective cohort study using multivariable logistic regression to identify associations of social vulnerability and enhanced recovery with outcomes.

SETTINGS

Institutional American College of Surgeons National Surgical Quality Improvement Program database.

PATIENTS

Patients undergoing elective colorectal surgery (2010-2020). Enhanced recovery programs were implemented in 2015. Those adhering to 70% or more of enhanced recovery program components were defined as enhanced recovery and all others as nonenhanced recovery.

OUTCOMES

Length of stay, complications, and readmissions.

RESULTS

Of 1523 patients, 589 (38.7%) were in the enhanced recovery group, with 625 patients (41%) in the lowest third of the Social Vulnerability Index, 411 (27%) in the highest third. There were no differences in Social Vulnerability Index distribution by the enhanced recovery group. On multivariable modeling, social vulnerability was not associated with increased length of stay, complications, or readmissions in the enhanced recovery group. Black race was associated with increased length of stay in both the nonenhanced recovery (OR 1.2; 95% CI, 1.1-1.3) and enhanced recovery groups (OR 1.2; 95% CI, 1.1-1.4). Enhanced recovery adherence was associated with reductions in racial disparities in complications as the Black race was associated with increased odds of complications in the nonenhanced recovery group (OR 1.9; 95% CI, 1.2-3.0) but not in the enhanced recovery group (OR 0.8; 95% CI, 0.4-1.6).

LIMITATIONS

Details of potential factors affecting enhanced recovery program adherence were not assessed and are the subject of current work by this team.

CONCLUSION

High social vulnerability was not associated with worse outcomes among both enhanced recovery and nonenhanced recovery colorectal patients. Enhanced recovery program adherence was associated with reductions in racial disparities in complication rates. However, disparities in length of stay remain, and work is needed to understand the underlying mechanisms driving these disparities. See Video Abstract .

COMPRENDIENDO EL IMPACTO DE LOS PROGRAMAS DE RECUPERACIN MEJORADA EN LA VULNERABILIDAD SOCIAL, LA RAZA Y LOS RESULTADOS DE LA CIRUGA COLORRECTAL

ANTECEDENTES:El aumento de la vulnerabilidad social medida por el índice de vulnerabilidad social se ha asociado con peores resultados quirúrgicos. Sin embargo, se sabe menos sobre el impacto de la vulnerabilidad social en los pacientes de cirugía colorrectal bajo programas de recuperación mejorados.OBJETIVO:Planteamos la hipótesis de que el aumento de la vulnerabilidad social se asocia con peores resultados antes de la implementación de la recuperación mejorada, pero después de la implementación, las disparidades en los resultados se reducirían.DISEÑO:Estudio de cohorte retrospectivo que utilizó regresión logística multivariable para identificar asociaciones de vulnerabilidad social y recuperación mejorada con los resultados.ESCENARIO:Base de datos institucional del Programa de Mejora Nacional de la Calidad de la Cirugía del American College of Surgeons.PACIENTES:Pacientes sometidos a cirugía colorrectal electiva (2010-2020). Programas de recuperación mejorada implementados en 2015. Aquellos que se adhieren a ≥70% de los componentes del programa de recuperación mejorada definidos como recuperación mejorada y todos los demás como recuperación no mejorada.MEDIDAS DE RESULTADO:Duración de la estancia hospitalaria, complicaciones y reingresos.RESULTADOS:De 1.523 pacientes, 589 (38,7%) estaban en el grupo de recuperación mejorada, con 732 (40,3%) pacientes en el tercio más bajo del índice de vulnerabilidad social, 498 (27,4%) en el tercio más alto, y no hubo diferencias en la distribución del índice vulnerabilidad social por grupo de recuperación mejorada. En el modelo multivariable, la vulnerabilidad social no se asoció con una mayor duración de la estancia hospitalaria, complicaciones o reingresos en ninguno de los grupos de recuperación mejorada. La raza negra se asoció con una mayor duración de la estadía tanto en el grupo de recuperación no mejorada (OR1,2, IC95% 1,1-1,3) como en el grupo de recuperación mejorada (OR1,2, IC95% 1,1-1,4). La adherencia a la recuperación mejorada se asoció con reducciones en las disparidades raciales en las complicaciones, ya que la raza negra se asoció con mayores probabilidades de complicaciones en el grupo de recuperación no mejorada (OR1,9, IC95% 1,2-3,0), pero no en el grupo de recuperación mejorada (OR0,8, IC95% 0,4-1,6).LIMITACIONES:No se evaluaron los detalles de los factores potenciales que afectan la adherencia al programa de recuperación mejorada y son el tema del trabajo actual de este equipo.CONCLUSIÓN:La alta vulnerabilidad social no se asoció con peores resultados entre los pacientes colorrectales con recuperación mejorada y sin recuperación mejorada. Una mayor adherencia al programa de recuperación se asoció con reducciones en las disparidades raciales en las tasas de complicaciones. Sin embargo, persisten disparidades en la duración de la estadía y es necesario trabajar para comprender los mecanismos subyacentes que impulsan estas disparidades.

Factors Associated With Diagnostic Delay in Axial Spondyloarthritis: Impact of Clinical Factors and Social Vulnerability

OBJECTIVE

Patients with axial spondyloarthritis (axSpA) often experience significant delay between symptom onset and diagnosis for reasons that are incompletely understood. We investigated associations between demographic, medical, and socioeconomic factors and axSpA diagnostic delay.

METHODS

We identified patients meeting modified New York criteria for ankylosing spondylitis (AS) or 2009 Assessment of Spondyloarthritis International Society criteria for axSpA in the Mass General Brigham health care system between December 1990 and October 2021. We determined the duration of diagnostic delay, defined as the duration of back pain symptoms reported at diagnosis, as well as disease manifestations and specialty care prior to diagnosis from the electronic health record. We obtained each patient's Social Vulnerability Index (SVI) by mapping their address to the US Centers for Disease Control SVI Atlas. We examined associations among disease manifestations, SVI, and diagnostic delay using ordinal logistic regression.

RESULTS

Among 554 patients with axSpA who had a median diagnostic delay of 3.8 years (interquartile range 1.1-10), peripheral arthritis (odds ratio [OR] 0.65, 95% confidence interval [CI] 0.45-0.93) and older age at symptom onset (OR 0.83, 95% CI 0.78-0.88 per five years) were associated with shorter delay. AS at diagnosis (OR 1.85, 95% CI 1.30-2.63), a history of uveitis prior to diagnosis (OR 2.77, 95% CI 1.73-4.52), and higher social vulnerability (defined as national SVI 80th to 99th percentiles; OR 1.99, 95% CI 1.06-3.84) were associated with longer diagnostic delay.

CONCLUSION

Older age at back pain onset and peripheral arthritis were associated with shorter delay, whereas uveitis was associated with longer diagnostic delay. Patients with higher socioeconomic vulnerability had longer diagnostic delay independent of clinical factors.

Modification of Firearm Law-Firearm Injury Association by Economic Disadvantage

INTRODUCTION

Firearm-related injuries in the U.S. have risen 37% since 2015. Understanding how the association between firearm incidents and state-level firearm restrictiveness is modified by community-level distress and economic connectedness (EC) may inform upstream injury prevention efforts.

METHODS

A national cross-sectional study of firearm incidents (interpersonal and unintentional firearm events) occurring between 1/2015 and 12/2021 was performed using the Gun Violence Archive. The exposures were community distress (Distressed Communities Index, DCI), EC, and year-state-level firearm restrictiveness. The primary outcome was mean annual urban firearm incidence rate per ZIP Code Tabulation Area. Generalized linear mixed models were fit to evaluate the modification of the firearm law-firearm incident association by DCI and EC. Data analyses took place in 2022.

RESULTS

About 266,020 firearm incidents were included. The mean rate was higher with each DCI tertile, with a RR of 3.18 (95% CI: 3.06, 3.30) in high versus low distress communities. Low EC was associated with over 1.8 times greater rate of firearm-related injury. The least restrictive firearm laws were associated with 1.20 times higher risk of firearm incidents (95% CI: 1.12, 1.28). The association between restrictive laws and lower incidence rates was strongest in low and medium distress and high EC communities.

CONCLUSIONS

Stricter firearm laws are associated with lower rate of firearm incidents. The magnitude of this association is smallest for communities experiencing the greatest economic disadvantage.

Changes in Older Adult Trauma Quality When Evaluated Using Longer-Term Outcomes vs In-Hospital Mortality

Importance

Lack of knowledge about longer-term outcomes remains a critical blind spot for trauma systems. Recent efforts have expanded trauma quality evaluation to include a broader array of postdischarge quality metrics. It remains unknown how such quality metrics should be used.

Objective

To examine the utility of implementing recommended postdischarge quality metrics as a composite score and ascertain how composite score performance compares with that of in-hospital mortality for evaluating associations with hospital-level factors.

Design, Setting, and Participants

This national hospital-level quality assessment evaluated hospital-level care quality using 100% Medicare fee-for-service claims of older adults (aged ≥65 years) hospitalized with primary diagnoses of trauma, hip fracture, and severe traumatic brain injury (TBI) between January 1, 2014, and December 31, 2015. Hospitals with annual volumes encompassing 10 or more of each diagnosis were included. The data analysis was performed between January 1, 2021, and December 31, 2022.

Exposures

Reliability-adjusted quality metrics used to calculate composite scores included hospital-specific performance on mortality, readmission, and patients' average number of healthy days at home (HDAH) within 30, 90, and 365 days among older adults hospitalized with all forms of trauma, hip fracture, and severe TBI.

Main Outcomes and Measures

Associations with hospital-level factors were compared using volume-weighted multivariable logistic regression.

Results

A total of 573 554 older adults (mean [SD] age, 83.1 [8.3] years; 64.8% female; 35.2% male) from 1234 hospitals were included. All 27 reliability-adjusted postdischarge quality metrics significantly contributed to the composite score. The most important drivers were 30- and 90-day readmission, patients' average number of HDAH within 365 days, and 365-day mortality among all trauma patients. Associations with hospital-level factors revealed predominantly anticipated trends when older adult trauma quality was evaluated using composite scores (eg, worst performance was associated with decreased older adult trauma volume [odds ratio, 0.89; 95% CI, 0.88-0.90]). Results for in-hospital mortality showed inverted associations for each considered hospital-level factor and suggested that compared with nontrauma centers, level 1 trauma centers had a 17 times higher risk-adjusted odds of worst (highest quantile) vs best (lowest quintile) performance (odds ratio, 17.08; 95% CI, 16.17-18.05).

Conclusions and Relevance

The study results challenge historical notions about the adequacy of in-hospital mortality as the single measure of older adult trauma quality and suggest that, when it comes to older adults, decisions about how quality is evaluated can profoundly alter understandings of what constitutes best practices for care. Composite scores appear to offer a promising means by which postdischarge quality metrics could be used.

Trends in disparities research on trauma and acute care surgery outcomes: A 10-year systematic review of articles published in The Journal of Trauma and Acute Care Surgery

ABSTRACT

This is a 10-year review of The Journal of Trauma and Acute Care Surgery (JTACS) literature related to health care disparities, health care inequities, and patient outcomes. A retrospective review of articles published in JTACS between January 1, 2013, and July 15, 2022, was performed. Articles screened included both adult and pediatric trauma populations. Included articles focused on patient populations related to trauma, surgical critical care, and emergency general surgery. Of the 4,178 articles reviewed, 74 met the inclusion criteria. Health care disparities related to gender (n = 10), race/ethnicity (n = 12), age (n = 14), income status (n = 6), health literacy (n = 6), location and access to care (n = 23), and insurance status (n = 13) were described. Studies published on disparities peaked in 2016 and 2022 with 13 and 15 studies respectively but dropped to one study in 2017. Studies demonstrated a significant increase in mortality for patients in rural geographical regions and in patients without health insurance and a decrease in patients who were treated at a trauma center. Gender disparities resulted in variable mortality rates and studied factors, including traumatic brain injury mortality and severity, venous thromboembolism, ventilator-associated pneumonia, firearm homicide, and intimate partner violence. Under-represented race/ethnicity was associated with variable mortality rates, with one study demonstrating increased mortality risk and three finding no association between race/ethnicity and mortality. Disparities in health literacy resulted in decreased discharge compliance and worse long-term functional outcomes. Studies on disparities in JTACS over the last decade primarily focused on location and access to health care, age, insurance status, and race, with a specific emphasis on mortality. This review highlights the areas in need of further research and funding in the Journal of Trauma and Acute Care Surgery regarding health care disparities in trauma aimed at interventions to reduce disparities in patient care, ensure equitable care, and inform future approaches targeting health care disparities.

Community-Level Social Vulnerability and Patterns of Adolescent Injury

Objective

To describe adolescent injuries by the community-level social vulnerability, focusing on injuries related to interpersonal violence.

Background

The Center for Disease Control and Prevention's social vulnerability index (SVI) is a tool used to characterize community-level vulnerability.

Methods

Injured adolescent trauma patients (13-17 years old) cared for at a large Level I trauma center over a 10-year period were identified. Injuries were classified by intent as either intentional or unintentional. Census tract level SVI was calculated by composite score and for 4 subindex scores (socioeconomic, household composition/disability, minority/language, housing type/transportation). Patients were stratified by SVI quartile with the lowest quartile designated as low-, the middle two quartiles as average-, and the highest quartile as high vulnerability. The primary outcome was odds of intentional injury. Demographic and injury characteristics were compared by SVI and intent. Multivariable logistic regression was used to estimate the adjusted odds of intentional injury associated with SVI.

Results

A total of 1993 injured adolescent patients (1676 unintentional and 317 intentional) were included. The composite SVI was higher in the intentional injury cohort (mean, SD: 66.7, 27.8 vs. 50.5, 30.2; P < 0.001) as was each subindex SVI. The high SVI cohort comprised 31% of the study population, 49% of intentional injuries, and 51% of deaths. The high SVI cohort had significantly increased unadjusted (odds ratio, 4.5; 95% confidence interval, 3.0-6.6) and adjusted (odds ratio, 1.8; 95% confidence interval, 1.6-2.8) odds of intentional injury.

Conclusions

Adolescents living in the highest SVI areas experience significantly higher odds of intentional injury. SVI and SVI subindex details may provide direction for community-level interventions to decrease the impact of violent injury among adolescents.

Socioeconomic Factors and Pediatric Injury

Purpose of Review

The goal of this review is to describe how socioeconomic status (SES) is evaluated in the pediatric trauma literature and further consider how differences in SES can lead to inequities in pediatric injury.

Recent Findings

Insurance status, area-level income, and indices of socioeconomic deprivation are the most common assessments of socioeconomic status. Children from socioeconomically disadvantaged backgrounds experience higher rates of firearm-related injuries, motor vehicle-related injuries, and violence-related injuries, contributing to inequities in morbidity and mortality after pediatric injury. Differences in SES may also lead to inequities in post-injury care and recovery, with higher rates of readmission, recidivism, and PTSD for children from socioeconomically disadvantaged backgrounds.

Summary

Additional research looking at family-level measures of SES and more granular measures of neighborhood deprivation are needed. SES can serve as an upstream target for interventions to reduce pediatric injury and narrow the equity gap.

Social Vulnerability and Emergency General Surgery among Medicare Beneficiaries

BACKGROUND

Although the Social Vulnerability Index (SVI) was created to identify vulnerable populations after unexpected natural disasters, its ability to identify similar groups of patients undergoing unexpected emergency surgical procedures is unknown. We sought to examine the association between SVI and outcomes after emergency general surgery.

STUDY DESIGN

This study is a cross-sectional review of 887,193 Medicare beneficiaries who underwent 1 of 4 common emergency general surgery procedures (appendectomy, cholecystectomy, colectomy, and ventral hernia repair) performed in the urgent or emergent setting between 2014 and 2018. These data were merged with the SVI at the census-track level of residence. Risk-adjusted outcomes (30-day mortality, serious complications, readmission) were evaluated using a logistic regression model accounting for age, sex, comorbidity, year, procedure type, and hospital characteristics between high and low social vulnerability quintiles and within the 4 SVI subthemes (socioeconomic status; household composition and disability; minority status and language; and housing type and transportation).

RESULTS

Compared with beneficiaries with low social vulnerability, Medicare beneficiaries living in areas of high social vulnerability experienced higher rates of 30-day mortality (8.56% vs 8.08%; adjusted odds ratio 1.07; p < 0.001), serious complications (20.71% vs 18.40%; adjusted odds ratio 1.17; p < 0.001), and readmissions (16.09% vs 15.03%; adjusted odds ratio 1.08; p < 0.001). This pattern of differential outcomes was present in subgroup analysis of all 4 SVI subthemes but was greatest in the socioeconomic status and household composition and disability subthemes.

CONCLUSIONS

National efforts to support patients with high social vulnerability from natural disasters may be well aligned with efforts to identify communities that are particularly vulnerable to worse postoperative outcomes after emergency general surgery. Policies targeting structural barriers related to household composition and socioeconomic status may help alleviate these disparities.
