PrEDICT: Predicting Emergency department Delirium with an Interactive Computer Tablet

2019

A tablet-based serious game that records target-tapping speed and accuracy at four difficulty levels to flag unrecognised delirium in older emergency patients. Its sensitive threshold was derived in one cohort and had modest specificity.

Format: PrEDICT presents target-tapping tasks of increasing difficulty and records time and accuracy automatically. The page should not invent the unpublished numerical threshold or represent the game as a complete diagnostic assessment.

CAM usually means the four-feature short form; the long form has ten items. Check which form and supporting assessment the study used. Short and long CAM explained.
