摘要

Intervention

In New Brunswick (NB), the Healthy Families, Healthy Babies (HFHB) public health program provides targeted perinatal services to first-time families at higher risk of poor outcomes. Research question: Does participation in the targeted HFHB prenatal program have a positive impact on select pregnancy and birth outcomes?

Methods

Population-based administrative datasets were linked to develop a matched retrospective cohort study of all first-time births in NB between April 1, 2012, and March 31, 2020, using propensity scores (PS) and nearest neighbour to select a matched group of nonparticipants. Multivariable regression models provided PS-adjusted risk difference estimates while accounting for remaining imbalanced confounding variables.

Results

A cohort of 20,832 births was established, among which 2000 were HFHB prenatal program participants. Overall results do not demonstrate a consistent positive impact of participation on the pregnancy (anemia, gestational diabetes) and birth (preterm birth, poor APGAR score, large for gestational age (GA), small for GA) outcomes examined. Program participation had a small but consistent impact on reduced risk of gestational hypertension (RD −1.3%, 95% CI −2.6 to 0%), which was similar when restricting to those under age 25. Measures of program intensity were examined, and results were consistent with the main analyses.

Conclusion

This study was embedded in a program review of the provincial perinatal program in NB. Results provide policy-relevant evidence to support program modification to improve population health outcomes. Linked administrative data, available through provincial data centres, are an efficient resource to conduct population-level outcome evaluations, supporting continuous system-level learning and quality improvement.
