Measurement of Long-term Outcomes
Stress Disorder, cognitive deterioration, fatigue
At discharge or at 30 days, whichever occurred first, participants were invited to a follow-up telephone interview at 6 months after randomization. The invitation did not require separate informed consent from the main study but did require an expression of willingness by the participant or participant’s representative to be contacted at approximately 6 months. To facilitate long-term cohort retention, we used a follow-up window of 5 to 8 months. Follow-up assessments were conducted through January 2020.During the follow-up telephone interview, we used a previously validatedTo assess psychological status, we used the Posttraumatic Stress Disorder 8-item questionnaire (PTSD-8)We used the Katz Activities of Daily Living ScaleTelephone interviews lasted approximately 60 minutes. In cases where the participant was unable or unwilling to undergo formal cognitive and psychological assessment by telephone (eg, due to illness, excessive fatigue, or cognitive deterioration), functional status and health care use data were gathered from a designated surrogate. Reasons for inability to participate in individual assessments were recorded.
