Two Easy-to-Use Scores to Identify Acute Geriatric Patients With High Rehabilitation Success

Area of Science:

• Geriatric Medicine
• Rehabilitation Science
• Health Services Research

Background:

• Geriatric patients often benefit from acute geriatric ward (AGW) stays.
• Lack of objective measures hinders identification of suitable candidates for AGW.
• Predictive tools are needed to assess rehabilitation success in geriatric patients.

Purpose of the Study:

• Develop and evaluate two standardized predictive scores: Discharged Home Score (DHS) and Barthel Index Improvement Score (BIS).
• Identify geriatric patients who would benefit from an AGW stay by predicting rehabilitation success.
• Facilitate timely and effective therapeutic interventions.

Main Methods:

• Retrospective cohort study involving 78,654 patient stays across 24 Austrian AGWs.
• Development of DHS (predicting post-AGW care situation) and BIS (predicting Barthel Index improvement) using regression models.
• Feature selection based on clinical discussion and statistical methods; evaluation on distinct datasets.

Main Results:

• DHS demonstrated strong predictive performance (AUC 0.775–0.827).
• BIS showed moderate predictive capability (AUC 0.692–0.711), explaining 17.7–22.1% of variance in Barthel Index improvement.
• Performance varied across different AGWs.

Conclusions:

• DHS and BIS offer a nuanced assessment of rehabilitation success in AGW patients.
• DHS is simpler to apply; BIS provides a more precise rehabilitation outcome prediction.
• Scores require further validation for clinical practice but show potential for improving patient identification and care.
