What this tool is and how to interpret its evidence
Published in 2012, I-CAM is described here as diagnostic assessment (episodic) for acute geriatric inpatients. The linked study examined it in General / acute hospital. The I-CAM commentary keeps the structure at domain level and does not reproduce prompts, rating anchors or the operational decision rule. For I-CAM, administration time varies with the version, setting or information available.
The linked source is Thomas C and colleagues, Diagnosing delirium in older hospitalized adults with dementia: adapting the confusion assessment method to international classification of diseases, tenth revision, diagnostic criteria in Journal of the American Geriatrics Society (2012); this catalogue treats it as original/source and earliest DTA study. For I-CAM, the evidence stage is one eligible diagnostic-accuracy study. The reconciled DTA dataset associates 1 eligible study with I-CAM. The earliest listed evaluation used Expert-panel ICD-10 delirium consensus as its reference standard.
The structured I-CAM result supports, but does not replace, clinical assessment of acute change and possible causes. For I-CAM, no verified public instrument form is recorded; the source article documents the tool but is not a substitute administration form.
