Program of intensive support in emergency departments for care partners of cognitively impaired patients: A randomized controlled trial5/21/2025Funded Investigator
(Article) Results of a randomized controlled trial of the Program of Intensive Support in Emergency Departments for Care Partners of Cognitively Impaired Patients (POISED) intervention, which was designed to identify cognitive impairment for patients at point of care in the ED, determine root causes for that ED visit, and apply an individualized post-ED care management plan for patients and care partners.  Despite a lack of demonstrated effectiveness, POISED offers insights for future development. A strategy to improve ED care for persons living with cognitive impairment or dementia might focus on gathering more actionable information at discharge rather than by care management after discharge.
