This diagnostic-accuracy study evaluated DEMS in 60-bed metropolitan-hospital aged-care precinct against a DSM-IV clinical assessment. It reported sensitivity of 76.3% and specificity of 75.8% in 100 analysed participants aged 65 years or older.

Format: DEMS is a clinical monitoring system with CAM-based and DOSS-based versions. Its structure and timing depend on the selected pathway, so a single item count or administration time would be misleading.
Evidence
Reported metric context
Pilot of a nurse-completed monitoring system (DEMS-CAM / DEMS-DOSS); completion 79% / 68% on a psychogeriatric ward.
