A social care system implemented in pediatric primary care: A cluster RCT

OBJECTIVES: To assess the implementation and effectiveness of the augmented WE CARE social care system on low-income children's health care utilization and child maltreatment outcomes. METHODS: We conducted a type 1 hybrid effectiveness-implementation cluster randomized controlled trial at 6 community health centers. Full-term infants were followed from birth to age 3. The 3 experimental clinics implemented the augmented WE CARE system at well-child visits, consisting of a self-report screening instrument for 7 basic needs; an electronic health record-generated resource information referral system; and access to a peer patient navigator. Families at control community health centers received usual care; 1 control site was contaminated and removed from primary analysis. We analyzed results using generalized mixed-effects models. RESULTS: Overall, 878 children were followed until age 3. Implementation of WE CARE was poor with only 28.9% of visits having a WE CARE screener documented. WE CARE families received significantly more resource referrals than control families (43.1% vs 1.9%, adjusted odds ratio 4.6; 95% confidence interval, 2.0-5.6); 20% were referred to the patient navigator. WE CARE children had significantly higher immunization adherence ratios. Although there were no statistically significant differences with well-child visits, WE CARE children had higher rates of emergency department visits than control children. By age 3, WE CARE children had significantly higher hospitalization rates (14.1% vs 10.4%, adjusted odds ratio 1.3, 95% confidence interval: 1.03-1.7). There were no statistically significant differences with maltreatment outcomes. CONCLUSIONS: We found poor implementation and mixed benefits for the augmented WE CARE system on immunization, health care utilization, and maltreatment outcomes in early childhood.
