Insights
Early intervention (EI) referral is inequitable for substance-exposed newborns (SENs). Factors like substance type and maternal insurance impact access, highlighting the need for systemic improvements.
Area of Science:
- Neonatal care
- Developmental pediatrics
- Public health
Background:
- Substance-exposed newborns (SENs) face developmental risks.
- Equitable access to early intervention (EI) services is critical for mitigating these risks.
- Current EI access for SENs is known to be inequitable.
Purpose of the Study:
- To determine the prevalence of EI referral among SENs in a collaborative.
- To identify predictors associated with EI referral for SENs.
- To evaluate disparities in EI referral based on substance exposure and insurance status.
Main Methods:
- Retrospective analysis of maternal-infant dyads with substance exposure documented in electronic medical records.
- Statistical comparison of maternal/infant characteristics based on EI referral status using chi-squared, Fisher's exact, and ANOVA tests.
- Multivariable Poisson regression models to assess independent associations between characteristics and EI referral.
Main Results:
- Only 41% (504/1222) of identified SENs received EI referral.
- Infants exposed to non-MOUD or polysubstances had lower referral rates compared to MOUD-exposed infants.
- Infants with private or self-pay/no insurance had significantly lower referral rates than those with public insurance.
Conclusions:
- Less than half of SENs received necessary EI services, indicating a significant gap in care.
- Referral rates varied substantially based on the type of substance exposure and maternal insurance status.
- Systemic changes are essential to ensure equitable EI service access for all SENs.
Objectives:
Substance-exposed newborns (SENs) are at risk for developmental delay(s). Early intervention (EI) access, key to addressing these risks, is inequitable. Objectives were to: 1. determine prevalence of EI referral in the Colorado Hospitals Substance-Exposed Newborn Quality Improvement Collaborative; and 2. evaluate predictors of referral.
Methods:
Within participating Colorado Hospitals Substance-Exposed Newborn hospitals, maternal-infant dyads with exposure to medications for opioid use disorder (MOUD), illicit/prescription opioids, and/or nonopioid substances were included on the basis of electronic medical record documentation. χ2, Fisher's exact, and analysis of variance tests evaluated differences in maternal/infant characteristics by referral. Multivariable Poisson regression models assessed the independent association of characteristics with referral.
Results:
Among 1222 dyads, 504 (41%) SENs received EI referral. Infants born to mothers with non-MOUD (adjusted risk ratio [aRR] 2.15, 95% confidence interval [CI] 1.67-2.76) and polysubstance (aRR 1.58, 95% CI 1.26-1.97) exposure were less likely to receive referral compared with infants born to mothers with MOUD exposure. Those with private (aRR 1.26, 95% CI 1.03-1.55) or self-pay/no insurance (aRR 12.32, 95% CI 10.87-13.96) were less likely to receive referral compared with infants with public insurance.
Conclusions:
Less than half of identified SENs received EI referral, with variation by substance exposure and maternal insurance status. Systems to ensure equitable access to services are crucial.
