Validation of the 3D-CAM and the UB-CAM in French

Study Overview
=================
Brief Summary
-----------------
Delirium is very common in hospitalized older patients and associated with serious clinical bad outcomes (e.g. increased risk of functional decline and death). Despite its high prevalence in the hospital setting, delirium remains underdiagnosed. A better identification would allow an early management and a reduction of its complications. The validation of easy-to-use and quick and formalized tools for the identification of delirium and their implementation in the clinical practice are necessary. Recently, the 3D-CAM (3-minutes Diagnostic interview for Confusion Assessment Method -defined delirium) and the UB-CAM (Ultra-Brief CAM) showed very high sensitivity and specificity (> 90%), compared to the reference standard (Diagnostic and Statistical Manual of Mental Disorders (DSM criteria)) for the diagnosis of delirium. The investigators aimed to evaluate the sensitivity and specificity of the French versions of the 3D-CAM and the UB-CAM used in delirium screening in older adults hospitalized in geriatric units, compared to reference standard.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Older adults hospitalized in acute geriatric units<br>Response to a questionnaire | Diagnostic Test: Delirium screening using 3D-CAM and UB-CAM<br>* Patients will be evaluated with 3D-CAM and UB-CAM by a trained examiner (geriatrician, resident or neuropsychologist). On the same day, they will be given a reference diagnosis of delirium based on DSM-V criteria by another trained examiner, blind to the results of the UB-CAM and 3D-CAM.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the performance of a rapid diagnostic tool (UB-CAM) for acute confusional state, translated into French | Presence or absence of a confusional state (with UB-CAM and the gold standard: DSM-V criteria) | At inclusion | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the time taken to use this tool | Completion time (minutes, seconds) | At inclusion | 
| Evaluation of the diagnostic performance of another diagnostic tool (3D-CAM), already translated into French | Presence or absence of a confusional state (with 3D-CAM and the gold standard: DSM-V criteria) | At inclusion |
