Implementing parity for mental health and substance use treatment in Medicaid.
Article in Health services research, 2020. 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 estimate the association between the implementation of parity in coverage for mental health and substance use disorder (MHSUD) services within the Medicaid program and MHSUD service use. DATA SOURCES/STUDY
settingWisconsin Medicaid enrollment and claims data from 2013 to 2015. In April 2014, Wisconsin Medicaid transitioned childless adult beneficiaries from coverage with limited MHSUD services to parity-consistent coverage. Preparity, they only had Medicaid coverage for MHSUD visits to psychiatrists and the emergency department, while parent beneficiaries had parity-consistent coverage. STUDY
designThe study uses a difference-in-differences design to compare outcome changes for childless adult and parent beneficiaries. DATA COLLECTION/EXTRACTION
methodsWe identified 76, 569 childless adult and parent beneficiaries aged 18-64 who were continuously enrolled for the 2-year study period. PRINCIPAL
findingsIntroducing parity-consistent coverage within Medicaid was associated with increased utilization of Medicaid-reimbursed MHSUD services: outpatient, prescription medication, ED, and inpatient. Increased MHSUD outpatient visits were driven by increased visits to nonpsychiatrists.
conclusionsParity's effects on MHSUD service use have been studied in the context of private insurance, but its impact among Medicaid beneficiaries has not. Our findings suggest that parity implementation in Medicaid could increase access to effective MHSUD services in a high-need population.
