Association of Medicaid Accountable Care Organizations and postpartum mental health care utilization.
Article in Health services research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo examine the association of Massachusetts Medicaid Accountable Care Organization (ACO) implementation with changes in mental health care utilization in the postpartum period. STUDY SETTING AND
designWe examine care for people with a birth covered by Medicaid or private insurance. We used a difference-in-differences design to compare differences before and after Medicaid ACO implementation for those with Medicaid versus those with private insurance. The primary outcome was a binary measure of having at least one outpatient mental health care visit in the 6 months postpartum. We estimated linear probability models controlling for age, prenatal mental illness, pregnancy complications, birth mode, and ZIP code characteristics. DATA SOURCES AND ANALYTIC SAMPLE: Data are from the Massachusetts All-Payer Claims Database. The analytic sample included Massachusetts residents with a live birth between July 1, 2016, and September 30, 2019, with complete data. PRINCIPAL
findings107,813 births were included (53.0% Medicaid, 47.0% private). 7.8% of these had at least one outpatient mental health visit in the 6 months postpartum, with similar rates among those with Medicaid versus those with private insurance pre-ACO implementation (7.9% Medicaid versus 7.7% private). An increase in utilization among privately insured individuals and a decrease among Medicaid beneficiaries post-ACO implementation was observed. Regression-adjusted difference-in-differences estimates indicate that Medicaid ACO implementation was associated with a 1.3 percentage point [pp] decrease (95% confidence interval: 1.3 pp, -0.5 pp; p < 0.01) in the probability of having an outpatient mental health visit for those with Medicaid.
conclusionsMedicaid ACO implementation was associated with decreases in use of outpatient mental health care in the postpartum period among people with Medicaid, overall and compared to those with private insurance. Future research should determine whether this increased disparity in mental health care utilization persists with maturation of the ACO delivery model.
