Association of Brain Atrophy and Masseter Sarcopenia With 1-Year Mortality in Older Trauma Patients

Abstract

Masseter muscle sarcopenia and brain atrophy were independently and cumulatively associated with 1-year mortality in older trauma patients after adjustment for other clinical factors. These radiologic indicators are easily measured opportunistically through standard imaging software. The results can potentially guide conversations regarding prognosis and interventions with patients and their families.
