Insights
Social vulnerability index (SVI) did not significantly impact infant outcomes for congenital anomalies. Further research is needed to explore healthcare inequities in these high-risk surgical patient populations.
Area of Science:
- Medical research
- Public health
- Socioeconomic impact on health
Background:
- The Social Vulnerability Index (SVI) is a tool used to assess community risk based on location.
- Understanding how SVI influences health outcomes in vulnerable populations is crucial for targeted interventions.
- Congenital anomalies requiring surgical treatment represent a high-risk group where social factors may play a significant role.
Purpose of the Study:
- To evaluate the impact of the Social Vulnerability Index (SVI) on pregnancy and infant outcomes.
- To investigate the association between SVI quartiles and infant morbidity and mortality in surgically treated congenital anomalies.
- To explore secondary outcomes including prenatal care access and maternal comorbidities in relation to SVI.
Main Methods:
- Retrospective study of 295 pregnant patient and infant dyads with surgically treatable congenital anomalies (2014-2022).
- Dyads were categorized into SVI quartiles (low, low-medium, medium-high, high).
- Bivariate analyses and odds ratios were used to compare outcomes across SVI quartiles, controlling for other indices like Area Deprivation Index.
Main Results:
- No significant association was found between SVI quartile and infant morbidity or mortality.
- The highest SVI quartile showed a nonsignificant trend towards increased odds of poor infant outcomes (OR: 1.57, 95% CI: 0.32-6.4).
- Fetal MRI was the only prenatal service associated with SVI quartile, but without a clear directional trend.
Conclusions:
- Social Vulnerability Index quartile was not significantly associated with infant outcomes in surgically treated congenital anomalies.
- Healthcare inequities related to social vulnerability in congenital surgical pathologies warrant further investigation.
- Future research should examine the long-term impact of SVI on perinatal and postnatal outcomes in high-risk populations.
Objective:
The social vulnerability index (SVI) is a place-based index used to stratify community risk. We evaluated the impact of SVI on pregnancy and infant outcomes in patients with surgically treatable congenital anomalies.
Study Design:
This is a retrospective study of pregnant patients and infant dyads diagnosed from 2014 to 2022 with congenital anomalies amenable to surgical treatment. Dyads were grouped into SVI quartiles. Primary outcomes were infant morbidity and mortality, and secondary outcomes included prenatal care services, pregnancy course characteristics, and pregnant person co-morbidities. The area deprivation index and child opportunity index were also collected. Bivariate comparisons of patient characteristics and unadjusted odds ratios for death or morbidity stratified by SVI quartile were performed.
Results:
Two hundred and ninety-five dyads met the inclusion criteria. Ten point two percent had low SVI, 23.7% low-medium, 35.3% medium-high, and 30.9% high. The only prenatal care service associated with SVI quartile was fetal MRI (p = 0.038), but no directional trend was observed. Infant diagnoses included 11.5% congenital diaphragmatic hernia, 27.5% gastroschisis, 18.6% intestinal atresia, 9.2% lower urinary tract obstruction, 20.3% myelomeningocele, 9.2% omphalocele, 0.3% sacrococcygeal teratoma, 8.5% tracheoesophageal fistula. The odds ratio of poor infant outcomes by SVI quartile showed a nonsignificant elevated odds ratio in the highest quartile SVI (low-medium SVI OR: 0.66 [95% CI: 0.14, 2.35], medium-high SVI OR: 0.78 [95% CI: 0.17, 2.63], and high SVI OR: 1.57 [95% CI: 0.32, 6.4]).
Conclusion:
SVI quartile was not associated with infant outcomes in patients with surgically treatable congenital anomalies. Future studies should examine the impact of SVI or other indices of social vulnerability on perinatal and long-term postnatal outcomes in these high-risk patients.
Key Points:
· Healthcare inequities warrant exploration in congenital surgical pathologies.. · Explored SVI quartile association with infant outcomes.. · Primary outcomes were not associated with SVI quartile.. · Nonsignificantly higher odds of poor outcome in patients with high SVI quartile..
