Study visits
Participants in both the diary intervention and the control group completed three study visits: (1) a baseline/pre-intervention session, (2) a post-intervention session at the end hospital care for the CA, and (3) a follow-up session 30 days after the end of hospital care. During the baseline/pre-intervention session, participants provided verbal consent, were randomized, and completed a questionnaire. Participants randomized to the intervention group were given verbal and written instructions to complete the ICU diary, received a hard-cover diary and pen, and were asked to start writing in the ICU diary.The post-intervention session was conducted over the phone and occurred only if the CA patient survived and was discharged from the hospital. During this session, participants completed study questionnaires. The intervention ended at this time, and intervention participants were informed that continued usage of the ICU diary was optional.The follow-up session was also conducted over the phone. At this final assessment, participants again completed study questionnaires. Participants were compensated up to $100 for their time. Participants received $50 after completing the baseline/pre-intervention session ($25 for randomization and $25 for completing the baseline survey) and $50 for survey completion at the follow-up session. Payment was not contingent on adherence to the diary intervention.
