Classification of Injurious Fall Severity in Hospitalized Adults.

Area of Science:

• Healthcare Quality Improvement
• Patient Safety
• Nursing Informatics

Background:

• Hospital fall reporting systems use broad injury categories.
• The "Major" injury classification in the National Database of Nursing Quality Indicators (NDNQI) lacks precision.
• This imprecision hinders accurate assessment of fall-related harm, ranging from minor fractures to life-threatening conditions.

Purpose of the Study:

• To refine the "Major" injury classification within the NDNQI system.
• To develop a valid and reliable categorization for inpatient fall-related injuries.
• To improve the specificity of reporting severe fall outcomes.

Main Methods:

• Literature review and analysis of 85 injurious fall reports from an Academic Medical Center.
• Development of three subcategories (Major A, B, C) based on injury type, functional impairment, and mortality risk.
• Creation of an administration manual and expert consensus for classification.

Main Results:

• The "Major" category was divided into Major A (temporary impairment), Major B (long-term impairment/increased mortality risk), and Major C (established mortality risk).
• Excellent interrater reliability (kappa = .96) was achieved after testing and validation.
• Distribution of injuries was Major A (40.3%), Major B (16.1%), and Major C (43.6%).

Conclusions:

• The proposed subcategories significantly enhance the existing NDNQI injury categorization.
• An administration manual enables trained personnel to reliably classify major fall injury severity.
• This refinement improves data accuracy for patient safety initiatives and quality improvement efforts.
