Social vulnerability index (SVI) and poor postoperative outcomes in children undergoing surgery in California

Assessing the Impact of Neighborhood and Built Environment on Pediatric Perioperative Care: A Systematic Review of the Literature

CONTEXT

Neighborhood and built environment encompass one key area of the Social Determinants of Health (SDOH) and is frequently assessed using area-level indices.

OBJECTIVE

We sought to systematically review the pediatric surgery literature for use of commonly applied area-level indices and to compare their utility for prediction of outcomes.

DATA SOURCES

A literature search was conducted using PubMed, Ovid MEDLINE, Ovid MEDLINE Epub Ahead of Print, PsycInfo, and an artificial intelligence search tool (1/2013-2/2023).

STUDY SELECTION

Inclusion required pediatric surgical patients in the US, surgical intervention performed, and use of an area-level metric.

DATA EXTRACTION

Extraction domains included study, patient, and procedure characteristics.

RESULTS

Area Deprivation Index is the most consistent and commonly accepted index. It is also the most granular, as it uses Census Block Groups. Child Opportunity Index is less granular (Census Tract), but incorporates pediatric-specific predictors of risk. Results with Social Vulnerability Index, Neighborhood Deprivation Index, and Neighborhood Socioeconomic Status were less consistent.

LIMITATIONS

All studies were retrospective and quality varied from good to fair.

CONCLUSIONS

While each index has strengths and limitations, standardization on ideal metric(s) for the pediatric surgical population will help build the inferential power needed to move from understanding the role of SDOH to building meaningful interventions towards equity in care.

The intersection of pediatric anesthesiology and social determinants of health

PURPOSE OF REVIEW

There is increasing evidence of racial and ethnic disparities in pediatric perioperative care, which indicates a need to identify factors driving disparities. Social determinants of health (SDOH) play a fundamental role in pediatric health and are recognized as key underlying mechanisms of healthcare inequities. This article summarizes recent research exploring the influence of SDOH on pediatric perioperative outcomes.

RECENT FINDINGS

Despite the scarcity of research exploring SDOH and pediatric perioperative outcomes, recent work demonstrates an association between SDOH and multiple outcomes across the perioperative care continuum. Measures of social disadvantage were associated with preoperative symptom severity, longer hospital stays, and higher rates of postoperative complications and mortality. In some studies, these adverse effects of social disadvantage persisted even when controlling for medical comorbidities and clinical severity.

SUMMARY

The existing literature offers compelling evidence of the impact of SDOH on perioperative outcomes in children and reveals a critical area in pediatric anesthesia that necessitates further exploration and action. To improve outcomes and address care inequities, future efforts should prioritize the integration of SDOH assessment into pediatric perioperative research and practice.

Neighborhood-level Disparities in Achievement of Social Continence Among School-aged Children With Anorectal Malformations: A Single-center Retrospective Study

BACKGROUND

Fecal incontinence is a common problem for children with repaired anorectal malformations (ARM) and has significant implications for initiating school. While sex, anatomy, and medical comorbidities are known to influence continence outcomes, the impact of socioeconomic factors and neighborhood-level disadvantage are less well understood.

METHODS

We performed a single-center retrospective review of all school-aged (5-18 years) children with ARM at a longitudinal pediatric surgery clinic. Demographic, clinical, and socioeconomic variables were abstracted via chart review and geocoding was performed to obtain Area Deprivation Index (ADI) and Social Vulnerability Index (SVI) scores. Statistical analyses assessed for associations between the primary outcome of social continence (defined as no diaper usage and infrequent fecal accidents at age 5) and these variables.

RESULTS

72 patients were included; of these, 45.8% were socially continent. On bivariate analysis, social continence was significantly associated with state ADI score as well as the SVI Housing characteristics score. These associations remained significant when adjusting for sex and medical comorbidities in separate multiple logistic regression models.

CONCLUSION

The relative disadvantage of the neighborhood in which a child with ARM lives may play a role in their ability to achieve continence by school age. Efforts are warranted to identify and develop targeted interventions to for this pediatric population.

Using the Social Vulnerability Index to Analyze Statewide Health Disparities in Cholecystectomy

INTRODUCTION

Addressing the effects of social determinants of health in surgery has become a national priority. We evaluated the utility of the Social Vulnerability Index (SVI) in determining the likelihood of receiving cholecystectomy for cholecystitis in Texas.

METHODS

A retrospective study of adults with cholecystitis in the Texas Hospital Inpatient Discharge Public Use Data File and Texas Outpatient Surgical and Radiological Procedure Data Public Use Data File from 2016 to 2019. Patients were stratified into SVI quartiles, with the lowest quartile as low vulnerability, the middle two as average vulnerability, and the highest as high vulnerability. The relative risk (RR) of undergoing surgery was calculated using average vulnerability as the reference category and subgroup sensitivity analyses.

RESULTS

A total of 67,548 cases were assessed, of which 48,603 (72.0%) had surgery. Compared with the average SVI groups, the low vulnerability groups were 21% more likely to undergo cholecystectomy (RR = 1.21, 95% confidence interval [CI] 1.18-1.24), whereas the high vulnerability groups were 9% less likely to undergo cholecystectomy (RR = 0.91, 95% CI 0.88-0.93). The adjusted model showed similar results (RR = 1.05, 95% CI 1.04-1.06 and RR = 0.97, 95% CI 0.96-0.99, for low and high vulnerability groups, respectively). These results remained significant after stratifying for age, sex, ethnicity, and insurance status. However, the differences between low, average, and high vulnerability groups diminished in rural settings, with lower surgery rates in all groups.

CONCLUSIONS

Patients with higher SVI were less likely to receive an elective cholecystectomy. SVI is an effective method of identifying social determinants impacting access to and receipt of surgical care.

Sociodemographic Factors are Associated with Care Delivery and Outcomes in Pediatric Severe Sepsis

IMPORTANCE

Sepsis is a leading cause of morbidity and mortality in the United States and disparate outcomes exist between racial/ethnic groups despite improvements in sepsis management. These observed differences are often related to social determinants of health (SDoH). Little is known about the role of SDoH on outcomes in pediatric sepsis.

OBJECTIVE

This study examined the differences in care delivery and outcomes in children with severe sepsis based on race/ethnicity and neighborhood context (as measured by the social vulnerability index).

DESIGN SETTING AND PARTICIPANTS

This retrospective, cross-sectional study was completed in a quaternary care children's hospital. Patients 18 years old or younger who were admitted between May 1, 2018, and February 28, 2022, met the improving pediatric sepsis outcomes (IPSO) collaborative definition for severe sepsis. Composite measures of social vulnerability, care delivery, and clinical outcomes were stratified by race/ethnicity.

MAIN OUTCOMES AND MEASURES

The primary outcome of interest was admission to the PICU. Secondary outcomes were sepsis recognition and early goal-directed therapy (EGDT).

RESULTS

A total of 967 children met the criteria for IPSO-defined severe sepsis, of whom 53.4% were White/non-Hispanic. Nearly half of the cohort (48.7%) required PICU admission. There was no difference in illness severity at PICU admission by race (1.01 vs. 1.1, p = 0.18). Non-White race/Hispanic ethnicity was independently associated with PICU admission (odds ratio [OR] 1.35 [1.01-1.8], p = 0.04). Although social vulnerability was not independently associated with PICU admission (OR 0.95 [0.59-1.53], p = 0.83), non-White children were significantly more likely to reside in vulnerable neighborhoods (0.66 vs. 0.38, p < 0.001). Non-White race was associated with lower sepsis recognition (87.8% vs. 93.6%, p = 0.002) and less EGDT compliance (35.7% vs. 42.8%, p = 0.024).

CONCLUSIONS AND RELEVANCE

Non-White race/ethnicity was independently associated with PICU admission. Differences in care delivery were also identified. Prospective studies are needed to further investigate these findings.

Association of Hospice Agency Location and Neighborhood Socioeconomic Disadvantage in the U.S

BACKGROUND

Despite the growing increase in the utilization of hospice in the U.S, disparities exist in the utilization of hospice. Accumulating evidence has shown that neighborhood characteristics have an impact on availability of hospice agencies.

OBJECTIVE

To assess the association between neighborhood social vulnerability and hospice agency availability.

METHODS

Using the Medicare Post-Acute Care and Hospice Provider Utilization and Payment Public Use Files (PAC PUF) for 2019. Hospice agency addresses were geocoded to the census tract level. Multivariable Poisson regression models were used to assess the association between socioeconomic status SVI theme and hospice agency availability adjusting for number of home health agencies, primary care health profession shortage, per cent Black, and Percent Hispanic at the census tract level and rurality.

RESULTS

The socioeconomic status SVI subtheme was associated with decreased likelihood of hospice agency availability (adjusted IRR (aIRR), .56; 95% CI, .50- .63; P < .001). Predominantly Black, and predominantly Hispanic neighborhoods had lower rates of hospice agency availability (aIRR, .48; 95% CI, .39-.59; P < .001 and aIRR, .29; 95% CI, .24-.36; P < .001), respectively.

CONCLUSION

Neighborhood socioeconomic disadvantage was associated with lower availability of hospice agencies. Policies aimed at increasing access to hospice should be cognizant of neighborhood socioeconomic disadvantage.

Associations Between Social Vulnerability Indicators and Pediatric Tonsillectomy Outcomes

OBJECTIVE

To investigate the impact of neighborhood-level social vulnerability on pediatric tonsillectomy outcomes.

METHODS

This single-center retrospective cohort study included tonsillectomies performed on children aged 1 to 18 between August 2019 and August 2020. Geographic information systems were used to geocode addresses, and spatial overlays were used to assign census-tract level social vulnerability index (SVI) scores to each patient. For categorical variables, two-sided Pearson chi-square tests were used, whereas for continuous variables, paired t-tests, means, and standard deviations were calculated. SVI and its four subthemes were investigated using binomial logistic regressions to determine their impact on post-T&A complications and readmissions.

RESULTS

The study included 397 patients, with 52 having complications (13.1%) and 33 (8.3%) requiring readmissions due to their complications. Controlling for age, gender, race, insurance status, surgical indication, comorbidities, obesity, and obstructive sleep apnea, postoperative complications were associated with high overall SVI (odds ratio [OR] 5.086, 95% confidence interval [CI] 1.128-22.938), high socioeconomic vulnerability (SVI theme 1, OR 6.003, 95% CI 1.270-28.385), and high house composition vulnerability (SVI theme 2, OR 6.340, 95% CI 1.275-31.525). Readmissions were also associated with high overall SVI (10.149, 95% CI 1.293-79.647) and high housing/transportation vulnerability (SVI theme 4, OR 5.657, 95% CI 1.089-29.396).

CONCLUSION

Social vulnerability at the neighborhood level is linked to poorer surgical outcomes in otherwise healthy children, suggesting a target for community-based interventions. Because of the increased risk, it may have implications for preoperative decision-making, treatment plans, and clinic follow-ups.

Prevalence and Geographic Features of Patients Eligible for Extracorporeal Cardiopulmonary Resuscitation

OBJECTIVE

This study sought to identify Out of Hospital Cardiac Arrests (OHCA) eligible for Extracorporeal Cardiopulmonary Resuscitation (ECPR), use Geographic Information Systems (GIS) to investigate geographic patterns, and investigate if correlation between ECPR candidacy and Social Determinants of Health (SDoH) exist.

METHODS

This study is of emergency medical service (EMS) runs for OHCA to an urban medical center from January 1, 2016 to December 31, 2020. All runs were filtered to inclusion criteria for ECPR: age 18-65, initial shockable rhythm, and no return of spontaneous circulation within initial defibrillations. Address level data were mapped in a GIS. Cluster detection assessed for granular areas of high concentration. The Center for Disease Control and Prevention (CDC) Social Vulnerability Index (SVI) was overlaid. The SVI ranges from 0-1 with higher values indicating increasing social vulnerability.

RESULTS

There were 670 EMS transports for OHCA during the study period. 12.7% (85/670) met inclusion criteria for ECPR. 90% (77/85) had appropriate addresses for geocoding. Three geographic clusters of events were detected. Two were residential areas and one was concentrated over a public use area of downtown Cleveland. The SVI for these locations was 0.79, indicative of high social vulnerability. Nearly half (32/77, 41.5%) occurred in neighborhoods with the highest level of social vulnerability (SVI ≥0.9).

CONCLUSION

A significant proportion of OHCAs were eligible for ECPR based on prehospital criteria. Utilizing GIS to map and analyze ECPR patients provided insights into the locations of these events and the SDoH that may be driving risk in these places.

Disparities in Hand Surgery Exist in Unexpected Populations

Background The purpose of our study is to investigate disparities in the patient populations and outcomes of carpal tunnel release (CTR) and trigger finger release (TFR).  Methods A retrospective review of 777 CTR and 395 TFR patients from May 2021 to August 2022 was completed. The shortened form of the Disabilities of the Arm, Shoulder, and Hand (DASH) scores (QuickDASH) was recorded to evaluate physical function preoperatively and at one and three months postoperatively. This study was deemed institutional review board-exempt by the institutional clinical research committee. Results Compared to CTR, TFR patients resided in zip codes with higher levels of social vulnerability across dimensions of 'household composition and disability' (p=0.018) and 'minority status and language' (p=0.043). When analyzing QuickDASH scores by demographics and procedure, preoperative scores were statistically significantly higher for non-married (p=0.002), White (p=0.003), and female sex (p=0.001) CTR patients. Further, one-month postoperative scores were statistically higher for White and non-married CTR patients (0.016 and 0.015, respectively). At three months postoperatively, female and non-married patients had statistically significant higher scores (0.010 and 0.037, respectively). In TFR patients, one-month postoperative QuickDASH scores for White and female patients were statistically significantly higher (0.018 and 0.007, respectively). There were no significant differences in QuickDASH scores between rural and non-rural patients, household income (HHI) above or below the median, or the Social Vulnerability Index (SVI) dimensions.  Conclusion Our study found marital status, sex, and race were associated with disparities in pre-and postoperative physical function in patients undergoing carpal tunnel or trigger finger release. However, future studies are warranted to confirm and develop solutions to disparities within this population.

The past, present and future of ACS NSQIP-Pediatric: Evolution from a quality registry to a comparative quality performance platform

Quality and process improvement (QI/PI) in children's surgical care require reliable data across the care continuum. Since 2012, the American College of Surgeons' (ACS) National Surgical Quality Improvement Program-Pediatric (NSQIP-Pediatric) has supported QI/PI by providing participating hospitals with risk-adjusted, comparative data regarding postoperative outcomes for multiple surgical specialties. To advance this goal over the past decade, iterative changes have been introduced to case inclusion and data collection, analysis and reporting. New datasets for specific procedures, such as appendectomy, spinal fusion for scoliosis, vesicoureteral reflux procedures, and tracheostomy in children less than 2 years old, have incorporated additional risk factors and outcomes to enhance the clinical relevance of data, and resource utilization to consider healthcare value. Recently, process measures for urgent surgical diagnoses and surgical antibiotic prophylaxis variables have been developed to promote timely and appropriate care. While a mature program, NSQIP-Pediatric remains dynamic and responsive to meet the needs of the surgical community. Future directions include introduction of variables and analyses to address patient-centered care and healthcare equity.
