Modified Nu-DESC: Modified Nursing Delirium Screening Scale

2019

A five-domain Nu-DESC version that makes the disorientation assessment more explicit. Its apparent accuracy gain was derived exploratorily in the same emergency-department cohort and requires independent validation.

At a glance

Purpose: Episodic assessment
Population: Adult
Setting: Emergency department
Time: brief routine nurse screen; exact completion time not reported in the validation abstract
Items: 5
Score or threshold: Study-derived modified Nu-DESC classification; use the publication for the exact rule

Format: Modified Nu-DESC preserves the parent scale's five scored domains while adding two standard orientation checks within the disorientation domain. The publication should be used for the full scoring rule; this summary is not a replacement form.
