The Association of Social Vulnerability With Maternal and Fetal Outcomes in a Cardio-Obstetrics Cohort
Authors' conclusion
The cardio-obstetric referral population exhibited a high overall SVI. Higher social vulnerability was associated with delayed access to care but not independently associated with most adverse maternal and fetal pregnancy outcomes.
Study context
- Population
- Patients referred to a cardio-obstetrics programindividuals included
- Participants
- 489 patients
- Exposure
- Risk of maternal and fetal outcomes by Social Vulnerability Index (SVI)
- Outcome
- Overall median SVI of the referral cohort
Methodological detailsall consecutive patients referred to our cardio-obstetrics program from March 2023 to January 2025
- All consecutive patients referred to our cardio-obstetrics program from March 2023 to January 2025
Main finding
As reported in the abstract
Overall median SVI
0.833
Observational data: associations, not effects.
Further findings
Characteristics associated with increasing SVI
- Increasing SVI was associated with younger age, higher BMI, Black race, and Medicaid insurance
Mean SVI by late entry to cardio-obstetrical care, neonatal intensive care unit admission, and fetal demise
- Mean SVI higher with late entry to cardio-obstetrical care
- P = 0.03
- Mean SVI higher with neonatal intensive care unit admission
- P = 0.04
- Mean SVI higher with fetal demise
- P < 0.001
Delayed cardio-obstetrical care
- Delayed cardio-obstetrical care was associated with high SVI
- Unadjusted regression analyses
Maternal and fetal outcomes
- SVI was not independently associated with most maternal and fetal outcomes
- Multivariable adjusted analyses
Discriminatory performance of SVI for fetal/neonatal demise
- Area under the curve
- 0.80; 95% CI: 0.68-0.92
- Discriminatory performance of SVI was highest for fetal/neonatal demise
