Abstract
Many critical care patients lack capacity due to disease or the need for sedation to facilitate invasive therapy. Research with incapacitated patients requires consent from a personal legal representative and upon regaining capacity retrospective consent from the patient [1]. Obtaining retrospective consent may delay data collection, requires additional research time, and consequently increases the cost of research.
