Evidence-based nursing combined with cognitive function training can reduce the incidence of delirium in ICU patients and improve their cognitive function.

Objective: To explore whether evidence-based nursing combined with cognitive function training can reduce the incidences of delirium in intensive care unit (ICU) patients and improve their cognitive function.

Methods: ICU patients in our hospital were randomly divided into an evidence-based nursing group (the E group) and an evidence-based nursing combined with cognitive function training group (the EC group). The incidences of delirium, the Pittsburgh Sleep Quality Index (PSQI) scores, the Mini-Mental State Exam (MMSE) scores, the National Institutes of Health Stroke Scale (NIHSS) scores, the Barthel Index levels, and the nursing satisfaction rates were compared between the two groups.
