Poor Outcomes Among Patients Aged 65 and Older Presenting to the Emergency Department(EDEN-RICAPPS Study)

Our objective is to create and validate predictive models of poor outcome in people over 65 years of age seen in emergency departments. To this end, models will be developed and validated internally, adapting the reference values of vital signs to this population segment and also taking into account their most frequent reasons for consultation. We will use the EDEN cohort of 18374 patients recruited in one week in 2019 in 40 Spanish hospitals. Subsequently, they will be externally validated in a cohort of 18000 patients prospectively recruited in 7 hospitals in 2024. In addition, the predictive capacity of the FIM frailty scale will be measured. lnformation will be collected from electronic medical records regarding socio-demographic data, functional status, reasons for consultation, clinical and ED history including comorbidities, previous and prescribed ED treatments and vital signs. The main dependent variable is poor outcome defined as ED exitus, admission to ICU/ICU or conventional admission, as well as mortality, revisits and readmissions 30 days after hospital discharge. Updated poor outcome models will be provided that can serve as a basis for creating triage models adapted to the over-65s in the future.
