Posttraumatic stress disorder symptoms in close relatives of intensive care unit patients: Prevalence data resemble that of earthquake survivors in Chile

Individual patient factors such as severity, age, and being on MV increase the occurrence of PTSD, as well as sex and baseline anxiety levels of caregivers. Preventative measures could be devised for this particular high-risk population.
