Utilization of an Electronic Health Record Embedded Enterprise Health Data Exchange: A Single Institute Experience.
Article in Journal of imaging informatics in medicine, 2025. 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
Evaluate the demand, volume, and institutional utilization of an EHR-based platform for health data exchange in a single US academic system. A retrospective review (3/2023-4/2024) spanned 11 hospitals and over 500 outpatient sites. Analytic reports from the Epic Care Everywhere Image Exchange Advanced Platform (Verona, WI) captured inbound (requested internally) and outbound (accessed externally) data volumes, including thumbnails and subsequent reference-quality key image retrievals. Data types were categorized as DICOM or non-DICOM (e.g., JPG, PDF). Counts, retrieval rates, and geographic patterns were analyzed. Inbound data involved 1.6 million patients from 370 external organizations, generating 5% for DICOM and 3% for non-DICOM; 77% of inbound thumbnails originated in-state. From 3/2023 to 4/2024, 1.9 million outbound thumbnails were accessed by 1478 external institutions, with a 78% reference-quality key image retrieval rate. Most outbound thumbnails were non-DICOM (66%); however, overall DICOM retrieval rates (5%) were higher than non-DICOM (3%). In-state institutions retrieved the most thumbnails (1,156,896/59%), whereas out-of-state sites requested more reference-quality key images (1,034,614/67%). Top users included various private and public health sectors. Findings show a growing reliance on EHR-embedded health data exchange. The abundance of inbound non-DICOM underscores interoperability challenges, while high DICOM retrieval rates emphasize clinical importance. Geographic disparities highlight the need for standardized solutions to improve continuity of care. Moreover, the upcoming HTI-2 bill mandates stronger data exchange measures, reinforcing the urgency for scalability. Health data exchange is in high demand as patients increasingly seek care across the US.
