Confusion: delirium and dementia - a smartphone app to improve cognitive assessment.

Older patients with dementia and delirium are more prone to adverse events in hospital, but formal cognitive assessment to identify these vulnerable patients on admission is often not carried out by junior doctors. A smartphone app was created and provided on hospital wards to facilitate the use of standard cognitive assessments for delirium and dementia. Before the introduction of the app, 36% of patients over 75 years old were assessed cognitively.
