DELIKT: DELIrium risK Tool

2023

A single-centre EHR-derived score for incident delirium risk in older non-ICU inpatients. It is a prediction model requiring external and implementation validation, not a current-delirium screen.

At a glance

Purpose
Future-risk prediction
Population
Older non-intensive-care hospital inpatients without delirium at baseline
Setting
General / acute hospital
Time
potentially automated from EHR data in the first 24 hours
Score or threshold
More than 20 points was associated with incident delirium in the source cohort; thresholds may be adapted and require external validation

Primary validation studies

Distinct primary publications from the current diagnostic-accuracy audit. Reviews and repeated evaluations within one paper are not counted again. Overlapping cohorts have not all been reconciled. Read the counting rules and limitations.

No eligible diagnostic-accuracy paper is currently included in this audit. This does not mean the tool has never been validated. The source paper and other evidence on this profile may concern severity, reliability or another measurement purpose.
