At a glance

Purpose
Measurement of delirium severity
Population
Adult
Setting
General / acute hospital

Items
12

Format: A 12-item nurse-rated behavioural scale for repeated delirium-severity observation, covering cognitive/motivational and psychotic/behavioural manifestations.

  • Strengths: Nurse-rated repeated monitoring; convergent, divergent and change-score validity reported
  • Limitations: Single geriatric general-hospital validation study; severity measure rather than diagnostic rule

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.
