Evaluation of the "medication fall risk score"

Area of Science:

• Gerontology
• Health Services Research
• Patient Safety

Background:

• Hospitalized patients are at high risk for falls, leading to adverse outcomes.
• Existing fall screening tools, like the Morse Fall Scale (MFS), have limitations in predictive accuracy.
• Medication review is a potential factor in fall risk assessment.

Purpose of the Study:

• To evaluate the predictive validity of the medication fall risk score (RxFS) when used with the Morse Fall Scale (MFS).
• To determine if combining RxFS and MFS improves fall risk prediction in hospitalized adults.

Main Methods:

• Retrospective analysis of administrative claims data from 33,058 hospitalized patients.
• Comparison of fall risk prediction using MFS alone versus MFS combined with RxFS.
• Utilized Receiver Operating Characteristic (ROC) curve and Net Reclassification Improvement (NRI) analyses.

Main Results:

• The combined MFS and RxFS model showed a significantly higher area under the ROC curve (0.8014) compared to MFS alone (0.7823, p=0.0030).
• Combined screening improved sensitivity to 82.42% and specificity to 66.65% compared to MFS alone (81.25% sensitivity, 61.37% specificity).
• Net reclassification improvement (NRI) was 0.0587 (p=0.0003), indicating better risk stratification.

Conclusions:

• Combining the RxFS tool with the MFS modestly improves the specificity of fall risk prediction in hospitalized patients.
• This dual-approach strategy enhances patient safety by more accurately identifying individuals at risk for falls without compromising sensitivity.
