Albumin and C-reactive protein relate to functional and body composition parameters in patients admitted to geriatric rehabilitation after acute hospitalization: findings from the RESORT cohort

Key summary points Aim To investigate the association between albumin and C-reactive protein during acute hospitalization with functional and body composition parameters in patients admitted to geriatric rehabilitation. Findings Lower average albumin, higher albumin variation and lower minimum albumin were associated with larger declines in physical function during acute hospitalization and with lower functional and body composition parameters at geriatric rehabilitation admission. C-reactive protein, was only partly associated with lower gait speed at geriatric rehabilitation admission. Message Inflammation during acute hospitalization, especially lower albumin concentrations, relates to declined physical function and low functional and body composition parameters upon geriatric rehabilitation admission.
