RMA — RADAR plus Months of the Year Backwards

What this tool is and how to interpret its evidence

RADAR plus Months of the Year Backwards (RMA) was introduced in 2024 for older acute hospital inpatients. It is a named delirium or acute-confusion assessment; the linked source defines the studied purpose and setting.

Published in 2024, RMA is described here as screening / case-finding for older acute hospital inpatients. The linked study examined it in General / acute hospital. The exact scored-item count for RMA is not confirmed in this catalogue record. For RMA, administration time varies with the version, setting or information available. The catalogue records the published scoring or threshold information as RMA positive.

The linked source is Soboh R and colleagues, Validation of a viable delirium detection test performed by nurses and physicians during routine patient care in BMC geriatrics (2024); this catalogue treats it as original/source and earliest DTA study. For RMA, the evidence stage is an implementation or workflow record with diagnostic-accuracy evidence. The reconciled DTA dataset associates 2 eligible studies with RMA. The earliest listed evaluation used 4AT-derived delirium classification (≥5; acute/chronic information partly supplied from RMA record) as its reference standard. The first recorded accuracy result reports sensitivity 93.9% and specificity 98.3%; the recorded sample is 384.

The RMA case-finding role should be kept separate from a full clinical diagnosis and investigation of underlying causes. For RMA, no verified public instrument form is recorded; the source article documents the tool but is not a substitute administration form.
