Importance of medical home domains on emergency visits using a cross-sectional national survey of US children.
Article in BMJ open, 2024. 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
BACKGROUND AND
objectivesReceiving care at patient-centred medical homes (PCMH) is associated with reduced emergency department (ED) visits among children. Adverse social determinants of health (SDoH), such as lower socioeconomic status and household poverty, are associated with increased ED visits in children. The objective of this study is to use machine learning techniques to understand the relative importance of each PCMH component among different populations with adverse SDoH on the outcome of ED visits. METHODS DESIGN, SETTING AND
participantsThis study used the 2018-2019 pooled data from the National Survey of Children's Health (NSCH), an annual survey of parents and caregivers of US children from birth to 17 years. PCMH components were operationalised by classifying parent/caregiver responses into five domains: care coordination (CC), having a personal doctor or nurse, having a usual source of care, family-centred care and ease of getting referrals. SDoH included five categories: (1) social and community context, (2) economic stability, (3) education access and quality, (4) healthcare access and quality and (5) neighbourhood and built environment. PRIMARY OUTCOME MEASURE: We used a split-improvement variable importance measure based on random forests to determine the importance of PCMH domains on ED visits overall and stratified by SDoH.
resultsOverall, between 3% and 28% experienced one or more gaps in PCMH domains. Models show that problems with referrals (rank, 2; Gini, 83.5) and gaps in CC (rank, 3; Gini, 81.0) were the two most important domains of PCMH associated with ED visits in children. This result was consistent among black and Hispanic children and among children with lower socioeconomic status.
conclusionsOur study findings underscore the importance of poor CC and referrals on ED visits for all children and those from disadvantaged populations. Initiatives for expanding the reach of PCMH should consider prioritising these two domains, especially in areas with significant minority populations.
