This article addresses the development and validation of a clinical prediction rule, using variables measurable upon hospital admission, to identify patients likely to develop delirium in hospital.
The main variables analysed and included in the prediction rule are (1) age 85 years old or older, (2) being dependent in five or more activities of daily living, and (3) taking two or more psychotropic drugs (antipsychotics, benzodiazepines, antidepressants, anticonvulsants and / or antidementia drugs).
The presence of these three predictive factors (age≥85, high level of dependence and psychotropic medication) makes it possible to rapidly classify patients on internal medicine wards according to their risk of developing delirium.
