Substance use treatment facility access and utilization among mothers in child welfare.
Article in Journal of substance use and addiction treatment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionDespite the severe consequences of substance use disorder (SUD), most Americans with SUD do not seek treatment. Uptake of treatment is especially important for mothers involved in the child welfare system (CWS), where SUD is common and can result in child maltreatment and loss of child custody. This study examines how local treatment accessibility influences utilization among CWS-involved mothers.
methodsOur sample includes 98,343 CWS referrals in Pennsylvania (2015-2019) in which the referred biological mother was receiving Medicaid. Using geocoded referral addresses and SUD treatment facilities statewide, we estimate how the drive time to and supply of SUD treatment is associated with maternal treatment uptake in the quarter following the referral. Given lack of consensus regarding the distance individuals will travel for SUD treatment (service areas), we consider multiple versions of our measures and allow operationalization of service areas to vary by county urbanicity and SUD treatment type. We use hierarchical logistic regression models with conditional autoregressive random effects to account for spatial autocorrelation to estimate treatment utilization.
resultsDrive time is associated with lower outpatient utilization, particularly in large metropolitan areas with broader service area definitions. Greater treatment supply is associated with increased outpatient and inpatient utilization, with the magnitudes being higher for inpatient care. For both measures, levels of significance depend on urbanicity.
conclusionsThe associations between the accessibility measures and treatment uptake are statistically significant but relatively small in magnitude. Greater attention to access barriers beyond drive time and supply of SUD treatment is needed to increase uptake among child welfare-involved mothers.
