Associations Between Frailty, Illness Severity, and Long-Term Mortality Among Older Adults Admitted to Municipal Acute Care

Important risk factors for mortality include frailty and illness severity. The National Early Warning Score 2 (NEWS2) is widely used to assess acute illness severity and mortality risk, but age and frailty's impact on the association between NEWS2 and mortality is less understood, particularly in nonhospital settings. This study aimed to examine the associations between frailty, NEWS2, and 1-year postdischarge mortality in older adults admitted to the Oslo Municipal In-Patient Acute Care (MipAC) unit.
