Researchers built a continuously updating sepsis severity score from routine hospital chart data, trained on records from two US hospital systems. Patients who later died scored consistently higher than survivors across comparable baseline groups, and the score tracked changes in lactate within individual patients. The work is retrospective and the authors present it only as possible decision support alongside clinical judgement.
What changed
Sepsis severity scores in routine use rely on fixed variables and weights set decades ago.
What it unlocks
An hourly, continuously updating severity score for sepsis patients learned from patient records rather than fixed rules.
- 29,116 and 7,691 patients, two sites
- 1.19-1.64 points higher for non-survivors
- 43 charted variables over 72 hours
What you need to act on it
- retrospective research only, not deployed or cleared for clinical use
