PurposeTo measure the rate of recall of study participation and study attrition in survivors of acute respiratory distress syndrome(ARDS).Materials/MethodsIn this ancillary study of the Re-evaluation of Systemic Early neuromuscular blockade(ROSE) trial, we measured the rate of study participation recall 3 months following discharge and subsequent study attrition at 6 months. We compared patient and hospital characteristics, and long-term outcomes by recall. As surrogate decision-makers provided initial consent, we measured the rate of patient reconsent and its association with study recall.ResultsOf 487 patients evaluated, recall status was determined in 386(82.7%). Among these, 287(74.4%) patients recalled participation in the ROSE trial, while 99(25.6%) did not. There was no significant difference in 6-month attrition among patients who recalled study participation (9.1%) and those who did not (12.1%) (p = 0.38). Patient characteristics were similar between groups, except SOFA scores, ventilator-free days, and length of stay. 330(68%) were reconsented. Compared to those not reconsented, significantly more patients who were reconsented recalled study participation(78% vs. 66%;p = 0.01).ConclusionsOne in 4 ARDS survivors do not recall their participation in a clinical trial during hospitalization 3 months following hospital discharge, which did not influence 6-month attrition. However, more patients recall study participation if reconsent is obtained.Copyright © 2021. Published by Elsevier Inc.
