Hidden Structure of Care Coordination in Heart Failure Care Transitions: A Mixed-Method Network Analysis of Clinical Notes.
Article in Journal of cardiac failure, 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
introductionPatients with heart failure, especially those with lower socioeconomic position, are vulnerable to adverse outcomes of care fragmentation. Care coordination mitigates care fragmentation; however, a comprehensive assessment of relationships among all relevant clinicians that enable it is lacking. This explanatory sequential mixed-methods study explores how patients' clinician network characteristics relate to their social context and clinical outcomes following heart failure care transitions.
methodsWe conducted a bipartite social network analysis to describe clinician networks for 1269 patients first hospitalized with heart failure in a southeastern US health system. Networks were constructed using electronic health record notes 1 year before, during, and 1 year after the index hospitalization (January 2015-February 2020). We then used stratified purposive sampling to select 11 adults with diverse socioeconomic positions but similar illness severity and comorbidity. For these patients, we conducted qualitative chart reviews of their clinical notes. Each patient's clinician network size, density, and centrality were integrated with qualitative findings to explore clinician networks' relationship to patients' social context and outcomes.
resultsPatients with higher socioeconomic positions used fewer acute care services and lived longer. Their clinicians, particularly outpatient clinicians, tended to have denser and more centrally located team networks before the index hospitalization that persisted after the index hospitalization. Their telephone notes indicated more regular and reciprocal communication patterns between patients and clinicians.
conclusionsEarly involvement and better communication among clinician networks with greater density and centrality may help to explain better care transition outcomes observed among patients with higher socioeconomic positions.
