      Abstract

      Background

      Functional decline and frailty are common in older adults and influence the risk of adverse outcomes. We aimed to assess the value of a Barthel index at the Emergency Department (ED-BI) score in predicting 30-day mortality and ED reconsultation among older patients with acute infection.

      Methods

      We performed a prospective multicentre cohort study of older patients (≥75 years) diagnosed with acute infection in 69 Spanish EDs. Demographic, comorbidities, functional status, clinical and analytical data were collected. Unadjusted and adjusted logistic regression models were used to assess the association between ED-BI score, mortality and ED reconsultation.

      Results

      In total 1596 patients with a mean age of 84.7 years were included in the study and 51.7% female. The most frequent focus of infection was respiratory in 918 patients (57.5%). Patients with an ED-BI< 60 points were significantly older, predominantly female, more likely institutionalized and more urinary infections. When comparing patients with an ED-BI score ≥ 60 points with those< 60 points no differences were found in ED reconsultation but in the latter group mortality at 30-days was higher (p < 0.001).

      Conclusion

      An ED-BI score< 60 points appears to be a strong predictor of mortality at the 30-day follow up in older patients with acute infection.
