What this tool is and how to interpret its evidence

Published in 2023, 3D-DST is described here as diagnostic assessment (episodic) for hospitalized older adults. The linked study examined it in General / acute hospital. The 3D-DST commentary keeps the structure at domain level and does not reproduce prompts, rating anchors or the operational decision rule. For 3D-DST, administration time varies with the version, setting or information available.

The linked source is Wang J and colleagues, Accuracy of a clinical decision support system based on the 3-minute diagnostic interview for CAM-defined delirium: A validation study(✰) in Geriatric nursing (New York, N.Y.) (2023); this catalogue treats it as original/source and earliest DTA study. For 3D-DST, the evidence stage is an implementation or workflow record with diagnostic-accuracy evidence. The reconciled DTA dataset associates 1 eligible study with 3D-DST. The earliest listed evaluation used Psychiatrist DSM-5 delirium diagnosis as its reference standard.

The structured 3D-DST result supports, but does not replace, clinical assessment of acute change and possible causes. For 3D-DST, no verified public instrument form is recorded; the source article documents the tool but is not a substitute administration form.
