What the study found
Critically ill patients in Japan who joined a COVID-19 clinical trial often had poor understanding of the trial details, and some were not aware they had consented to participate.
Why the authors say this matters
The authors conclude that informed consent in this setting was difficult, and they say future work should improve the consent process and ongoing patient support to balance autonomy and public health needs in health emergencies.
What the researchers tested
The researchers used a qualitative study design with conventional content analysis. They conducted semi-structured interviews with 10 participants from the anticoagulation domain of the Randomized, Embedded, Multi-factorial, Adaptive Platform Trial for Community-Acquired Pneumonia (REMAP-CAP), all of whom had been hospitalized in a Japanese intensive care unit for severe COVID-19 and had given prospective informed consent.
What worked and what didn't
Three categories emerged: trial participation without awareness or adequate understanding; interpretation of trial participation experience with reference to personal circumstances; and emotions and thoughts evoked by trial participation. Details of the trials or interventions were poorly understood, and some participants were unaware they had consented to participate. Some participants expressed interest in future trials, while others remained uncertain about their experience.
What to keep in mind
The study included 10 participants from one trial domain in Japan, so its scope was limited. The abstract does not describe additional limitations beyond the note that these findings come from critically ill patients during the COVID-19 pandemic.
Key points
- Some critically ill participants did not realize they had consented to the trial.
- Trial and intervention details were poorly understood by participants.
- Interview analysis produced three categories about awareness, personal interpretation, and emotions.
- Some participants were interested in future trials, while others remained uncertain.
- The authors say informed consent and ongoing support should be improved in health emergencies.
