Association between frailty and outcomes in emergency department patients requiring emergency general surgery: a retrospective cohort study.

Of 683 patients (median age 76 years; 52.7% female), 38.2% were classified as living with frailty (Clinical Frailty Scale ≥5).

Frailty was associated with an increased risk of complications (aOR: 2.3; 95% CI: 1.5-3.6), prolonged hospital stay (+46.4%; 95% CI: 26.8-69.0%) and discharge to a location other than home (aOR: 2.1; 95% CI: 1.4-3.2).
