The study has two phases: Phase B and Phase C. The purpose of the Phase B study is to
determine the performance (sensitivity and specificity) of a smartphone application (DelApp)
to identify delirium in the whole inpatient sample. The study also aims to determine the
performance (sensitivity and specificity) of the DelApp to discriminate between delirium
(with or without dementia) and dementia (without delirium).
The purpose of the Phase C study is to determine the efficacy of the DelApp software
application in detecting delirium in unselected patients in an inpatient sample and to
determine the performance of the DelApp to discriminate between delirium and dementia. The
study also aims to explore the performance of the DelApp in tracking change in cognitive
function.

Primary | Diagnostic accuracy of the DelApp to discriminate between delirium (with or without dementia) and dementia (without delirium). | DelApp score against delirium diagnosed using DSM-5 criteria in groups with dementia and delirium. | Baseline | |
Secondary | Accuracy of DelApp in measuring delirium severity | DelApp score against score on Delirium Rating Scale revised 98 (DRS-R98). | Baseline | |
Secondary | Length of stay | length of stay in hospital | up to 3 months | |
Secondary | Mortality | Mortality at three months post assessment | 3 months | |
Secondary | Discharge location | Where patient is discharged to after hospital. e.g home, care home. | up to 3 months | |
Secondary | Accuracy of DelApp to measure within-subject change in attentional functioning and delirium status over time | Comparision of DelApp scores to DSM-5 criteria for delirium. | 2 weeks | |
Secondary | Inter-rater agreement of the DelApp | Assessed by comparing researcher assessment scores to the scores of clinical staff who are delirium specialists. | Baseline |
