Association Between Frailty Status and Readmissions in Hospitalized Patients With Systemic Lupus Erythematosus.

Area of Science:

• Rheumatology
• Geriatrics
• Health Services Research

Background:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease with significant healthcare utilization.
• Frailty is an emerging geriatric syndrome associated with adverse health outcomes.

Purpose of the Study:

• To investigate the association between frailty and adverse outcomes in hospitalized patients with SLE.
• To determine if frailty predicts readmission risk, inpatient mortality, and hospitalization costs in SLE patients.

Main Methods:

• Retrospective cohort study using the National Readmissions Database (NRD).
• Identified adult patients with SLE using ICD-10 codes.
• Assessed frailty using the Hospital Frailty Risk Score (HFScore).
• Analyzed readmission rates, inpatient mortality, and hospitalization costs using Cox proportional hazard models.

Main Results:

• 39,738 SLE patients were included; 18,385 were categorized as frail.
• Frail SLE patients exhibited higher comorbidity scores and longer hospital stays.
• Frailty was independently associated with a 10% increased risk of readmission.
• Frail patients experienced higher readmission rates, prolonged hospitalizations, and increased costs.

Conclusions:

• Frailty is a significant predictor of adverse outcomes in hospitalized SLE patients.
• Frailty assessment can aid in risk stratification for SLE patients.
• Identifying frail SLE patients allows for targeted interventions to reduce readmissions and mortality.
