SARC-F at the Emergency Department: Diagnostic Performance for Frailty and Predictive Performance for Reattendances...

Area of Science:

• Gerontology
• Emergency Medicine
• Geriatric Medicine

Background:

• Sarcopenia is linked to poor health outcomes, including mortality and functional decline.
• The utility of screening for sarcopenia in the Emergency Department (ED) is not well-established.

Purpose of the Study:

• To evaluate the SARC-F questionnaire's ability to diagnose frailty.
• To assess the SARC-F's predictive power for adverse health outcomes in older ED patients.

Main Methods:

• Secondary analysis of a quasi-experimental study conducted in a tertiary hospital ED.
• Utilized data from older adults (≥85 years) including demographics, frailty status (using Frailty Index as reference), and comorbidities.
• Compared diagnostic and predictive performance of SARC-F against established frailty measures and adverse outcomes (mortality, hospitalization, ED reattendance).

Main Results:

• SARC-F demonstrated superior diagnostic ability for frailty (AUC 0.92) compared to other instruments.
• An optimal cutoff score of ≥3 on SARC-F showed high sensitivity (91.4%) and specificity (83.3%) for frailty.
• SARC-F independently predicted acute hospitalization and ED reattendance at 3 months (Adjusted ORs 4.00 and 3.29, respectively).

Conclusions:

• The SARC-F questionnaire is a valuable tool for detecting frailty in the ED setting.
• Its predictive validity for adverse outcomes like hospitalization and reattendance supports its use for early intervention.
• Further research is recommended to confirm SARC-F's performance in diverse ED populations.
