Combined Nutritional Risk and Iron Deficiency as Indicators of 28-Day Mortality in Elderly Patients in the Emergency Department

1

The study enrolled 443 patients aged 60 years and older from the emergency department to assess nutritional risk and iron deficiency.
2

The overall 28-day mortality rate among participants was 22.8%, with the highest rate of 42.7% in patients with both high nutritional risk and iron deficiency.
3

Patients with high nutritional risk and iron deficiency had a mortality risk 4.9 times greater than those without these conditions.
4

Hemoglobin levels were identified as a strong independent protective factor against mortality in older emergency department patients.
5

The combination of nutritional risk, hemoglobin, and iron deficiency provided the best prediction of 28-day mortality with an AUC of 0.779.
