RESUMEN
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. After the app, the percentage of cognitive assessments improved to 63%. Improvements in cognitive assessments were most marked after individual teaching of the doctors on the wards in the use of the app and on making the app available on the ward tablets. The results of the study suggest that the introduction of a smartphone app for junior doctors can improve performance in cognitive assessment of older people.
