Terms & Conditions of Use

Early delirium detection is crucial but often requires extra data. This study developed an algorithm using routine clinical data to identify patients needing delirium clarification, streamlining assessments.

Area of Science:

Nursing Science
Clinical Informatics
Gerontology

Background:

Early detection of delirium is vital for preventing complications.
Current delirium assessments often necessitate extensive data collection, posing a challenge in clinical practice.
There is a need for efficient methods to identify patients requiring delirium assessment.

Purpose of the Study:

To develop an algorithm for calculating a "delirium - need for clarification" score.
To utilize existing clinical routine data for delirium risk stratification.
To compare established screening questionnaires with routine data for algorithm development.

Main Methods:

Comparison of commonly used delirium screening questionnaires.
Determination and expert validation of Aggregate Dimensions by nursing science experts.

Keywords:

Risk detection automation in healthcare delirium routine data
