The impact of frailty on intra-hospital survival in older patients with COVID-19 infection: the importance of early identification. SEMI-COVID National Registry.

Publication date: Jul 14, 2023

Emerging evidence suggests that frailty may be a significant predictor of poor outcomes in older individuals hospitalized due to COVID-19. This study aims to determine the prognostic value of frailty on intrahospital patient survival. This observational, multicenter, nationwide study included patients aged 70 years and older who were hospitalized due to COVID-19 in Spain between March 1 and December 31, 2020. Patient data were obtained from the SEMI-COVID-19 Registry of the Spanish Society of Internal Medicine. Frailty was assessed using the Clinical Frailty Scale. The primary outcome was hospital survival. Cox proportional hazards models were used to assess predictors of survival. A total of 1,878 participants (52% men and 48% women) were included, with 1,351 (71. 9%) survivors and 527 (28. 1%) non-survivors. The non-survivor group had higher mean age (83. 5 vs. 81 years), comorbidities (6. 3 vs. 5. 3 points on the Charlson index), degree of dependency (26. 8% vs. 12. 4% severely dependent patients), and frailty (34. 5% vs. 14. 7% severely frail patients) compared to survivors. However, there were no differences in terms of sex. Our results demonstrate that a moderate-severe degree of frailty is the primary factor independently associated with shorter survival [HR 2. 344 (1. 437-3. 823; p
