Screening instruments for identification of vulnerable older adults at the emergency department: a critical appraisal.

ABSTRACT

BACKGROUND: Early detection of vulnerable older adults at the emergency department (ED) and implementation of targeted interventions to prevent functional decline may lead to better patient outcomes. OBJECTIVE: To assess the level of agreement between four frequently used screening instruments ISAR-HP, VMS, InterRAI ED Screener and APOP. METHODS: Observational prospective cohort study in patients ≥ 70 years attending Dutch ED. RESULTS: The prevalence of vulnerability ranged from 19% (APOP) to 45% (ISAR-HP). Overall there was a moderate agreement between the screening instruments (Fleiss Kappa of 0.42 (p<0.001)). CONCLUSION: Depending on the screening instrument used, either only a small percentage or almost as many as half of the presenting patients will be eligible for targeted interventions, leading to large dissimilarities in working processes, resources and costs.
