[Coronavirus disease 2019 and frailty].

Area of Science:

• Gerontology
• Infectious Diseases
• Critical Care Medicine

Context:

• COVID-19 impacts individuals differently, with older adults and those with comorbidities at higher risk.
• Frailty is a key predictor of severe COVID-19 outcomes, affecting 10-15% of individuals over 65 in Central Europe.
• Healthcare systems face strain, prompting ethical debates on intensive care unit (ICU) allocation, often informed by frailty assessments.

Purpose:

• To investigate the correlation between frailty, assessed using the Rockwood Clinical Frailty Scale (CFS), and COVID-19 mortality.
• To analyze the impact of frailty on both short-term and long-term survival in COVID-19 patients.
• To highlight the risk of sarcopenia in older COVID-19 patients and the importance of rehabilitation.

Summary:

• Patients over 80 with COVID-19 face a 3.6-fold higher mortality risk than younger adults.
• Frailty (CFS scores 6-9) triples mortality risk compared to robust individuals (CFS 1-3), with a CFS cut-off of ≥6 predicting mortality in those over 65.
• Long-term survival is more strongly linked to pre-infection frailty than disease severity. Older patients (over 60) are prone to significant muscle mass loss during moderate to severe COVID-19.

Impact:

• Frailty assessment, particularly the CFS, is crucial for predicting COVID-19 mortality and guiding clinical decisions.
• Understanding frailty's role emphasizes the need for personalized rehabilitation strategies, including nutritional support and exercise, for post-hospitalization recovery.
• The significant muscle loss (sarcopenia) associated with COVID-19 underscores the importance of targeted interventions to improve patient outcomes and reduce long-term disability.
