When hospitals build their own AI: a comparison of the EU and US regulatory framework.
Review in BMJ digital health & AI, 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
Hospitals are increasingly shifting from being passive purchasers of artificial intelligence (AI) systems to active developers of medical AI, particularly in the form of in-hospital machine learning tools tailored to local clinical needs. This paper examines how the European Union (EU) and the USA regulate in-hospital-developed AI-based medical devices, focusing on the legal and institutional conditions that shape innovation, oversight and diffusion. Through a comparative analysis across three dimensions-responsiveness to clinical need, distribution of innovative capacity and pathways for scaling and diffusion-the paper shows that both systems enable hospital-based innovation but embed it in different regulatory logics. The EU adopts a structured model that treats hospitals as regulated innovators operating under defined institutional obligations, whereas the USA relies on a more permissive and less institutionally differentiated framework in which hospital innovation emerges as a by-product of general software regulation.
