Positive Toxicology Screens at Birth in Massachusetts

Background
Referral Disparity
Results

•Federal law requires drug-exposed infants (DEI) to be
referred to Part C Early Intervention (EI) services.1
•Methods to estimate the number of drug-exposed
infants (DEI) in a state are limited.
•There are no population-based data on subsequent
referral, evaluation, and eligibility of DEI once identified.
•There is evidence of bias in performing toxicology
screens at birth based on non-clinical factors;2 is there
bias in referral after a positive screen?

Discussion
Drug Exposed Infant Identification Algorithm
• General utility as a Public Health screening
tool.
• May identify only more serious drug users.
• Retrospective cohort, secondary data analysis using the Pregnancy to
Early Life Longitudinal (PELL) data system, a population-based,
longitudinally linked data system (Boston University School of Public
Health, the MA Dept. of Public Health, and the Centers for Disease
Control and Prevention). PELL links birth certificates of live births in
MA hospitals to MA residents to birth hospital records for the mother
and child (99% linkage rate); pre- and postnatal hospital inpatient,
emergency, & observational stay records of the mother and child; & EI
records.
• Developed the Drug-exposed Infant Identification Algorithm (DEIIA).
• Referral identified by linkages to EI data; generalized estimating
equations that account for maternal clustering used to model referral
predictors.

and institutional characteristics related to EI referral of DEI

Address referral disparities
• Positive toxicology screens should trigger
referral regardless of insurance.
• Investigate why privately insured not being
referred.
• Disparities found for Asian/Pacific Islanders,
mothers aged 17-24, mothers with some
college education or more, & rural residence.
• Target outreach to lower level of maternity
care hospitals.
• EI referrals must be made by directly by birth
hospitals before discharge; do not assume
other agencies will make referral or that
family will follow up on referral suggestion.
7,348 Drug-Exposed Infants
