Acute muscle wasting is associated with poor prognosis in older adults with severe community-acquired pneumonia

Key summary points Aim To investigate the impact of acute muscle wasting on 90-day mortality in older patients with severe community-acquired pneumonia using ultrasound and chest computed tomography. Findings Acute muscle wasting assessed by ultrasound and chest CT independently predicted all-cause 90-day mortality in older patients with severe community-acquired pneumonia. A higher muscle loss had an increased risk of 90-day mortality. Message Acute muscle wasting is an independent predictor of adverse outcomes in older patients with severe community-acquired pneumonia.
