Multinational Validation of the Intensive Documentation Index for ICU Mortality Prediction: Temporal Resolution and ICU Mortality

2026-03-23

Abstract excerpt

<h4>ABSTRACT</h4> Clinical documentation timestamps generate a continuous, zero-burden behavioral signal in the electronic health record. We developed the Intensive Documentation Index (IDI) and validated it in two independent cohorts: MIMIC-IV (26,153 U.S. ICU heart failure patients, primary outcome in-hospital mortality) and HiRID (33,897 Swiss all-ICU patients, primary outcome ICU mortality). In MIMIC-IV, the...
