Developing and Evaluating a Laboratory‐Based Frailty Index (FI‐Lab) for the Prediction of Long‐Term Health Outcomes in Systemic Lupus Erythematosus

Key Points

• The research aims to develop a frailty index from laboratory data to predict health outcomes in patients with systemic lupus erythematosus.
• Developed a frailty index using routinely collected laboratory variables.
• Evaluated the index for its predictive ability concerning health outcomes in systemic lupus erythematosus.
• Assessed the index's potential as a screening tool for subclinical frailty.
• The frailty index successfully predicted adverse health outcomes in patients.
• Demonstrated high reliability and validity based on laboratory variables.
• Indicates potential for early risk identification and intervention strategies.
