Risk for poor outcomes in older patients discharged from an emergency department: feasibility of four screening instruments.

Objectives: To compare the prognostic value of four screening instruments used to detect the risk for poor outcomes [in terms of likelihood of recurrent emergency department (ED) visits, hospitalizations, or mortality] for older patients discharged home from an ED in the Netherlands.

Methods: This is a prospective cohort study, which included all consecutive patients of at least 65 years discharged from the ED of a university teaching hospital in the Netherlands, between 1 December 2005, and 1 November 2006. Four screening instruments were tested: the identification of seniors at risk, the triage risk screening tool, and the Runciman and Rowland questionnaires.
