Normal gait, albumin and d-dimer levels identify low risk emergency department patients: a prospective observational cohort study with 365-day 100% follow-up

Abstract Background If survival could be reliably predicted many patients could be safely managed outside of hospital in an ambulatory care setting. Aim Comparison of common laboratory findings, co-morbidities, mobility and vital signs as predictors of mortality of acutely ill emergency department (ED) attendees. Design Prospective observational study. Methods Secondary analysis of 1334 consenting acutely ill patients attending a Danish ED. Results 67 (5%) out of 1334 patients died within 100 days. After logistic regression seven predictors of 100 days mortality remained significant: an albumin level ≤34 gm/l, D-dimer level >0.51 mg/l, an Asadollahi score (based on admission laboratory data and age) ≥12, a platelet count
