Quantifying surprise in clinical care: Detecting highly informative events in electronic health records with foundation models.
Article in Pacific Symposium on Biocomputing. Pacific Symposium on Biocomputing, 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
We present a foundation model-derived method to identify highly informative tokens and events in electronic health records. Our approach considers incoming data for the entire context of a patient's hospitalization to find surprising events. Context enables flagging anomalous events that rule-based approaches would consider within a normal range. We demonstrate that the events our model flags are significantly more useful than average events for predicting downstream patient outcomes and show that a fraction of events we identify as unsurprising can be safely dropped without an adverse impact on performance. Finally, we show how informativeness can help interpret the predictions of prognostic models trained on foundation model-derived representations.
