Health interoperability across phenotypes of family physician practices.
Article in Journal of the American Medical Informatics Association : JAMIA, 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
objectivesTo inform initiatives to improve the interoperability of healthcare data, we described the experience of distinct phenotypes of physicians when obtaining information from outside sources. MATERIALS AND
methodsA total of 6175 family physicians across the United States responded to information technology questions on the 2022 and 2023 American Board of Family Medicine Continuous Certification Questionnaire (100% response rate). Latent class analysis grouped physicians by individual and practice characteristics and then compared reported experience with interoperability.
resultsA 4-class model ("Safety Net," "Health System," "Independent Practice," and "Large Practice") best fit. Health system and large practice physicians (predominately Epic users) were more likely to report information was integrated in their Electronic Health Record (EHR) than independent practice physicians (38% and 40%, respectively, compared to 24%), and to report that information from organizations using the same EHR was usable (52% and 51%, respectively, compared to 25%). Safety net physicians were least likely to report that information from outside organizations was usable (17% compared to 23% of independent physicians). Between 42% and 50% of each phenotype reported commonly encountering external records with a large volume of low-value information. DISCUSSION: Independent practice and safety net physicians reported worse experience in some dimensions of interoperability, likely driven by differences in access to information from organizations using the same EHR. Many other challenges were consistent across physician phenotypes.
conclusionInitiatives to improve interoperability among physicians may be most effective if targeted at independent practices and safety net practices; however, broad improvements will be necessary to address similar challenges across phenotypes.
