Are patients comfortable consenting to clinical anesthesia research trials on the day of surgery?
Consent for clinical anesthesia research trials is often sought on the day of surgery when patients are most anxious and have little privacy or time for reflection. We conducted a retrospective survey of patients' perceptions and concerns regarding consent for clinical anesthesia trials on the day of surgery. Questionnaires were mailed to 175 patients who had participated in 1 of 6 negligible- or minimal-risk clinical anesthesia trials within the preceding year. Seventy-six patients responded (43%). Most patients (80%) reported that they understood the purpose of their trial, did not feel obligated (61%) or pressured (67%) to participate, and were satisfied (mean visual analog scale: 71 mm) with the recruitment and consent process on the day of surgery. Few patients (7%) believed that their well-being was put at risk because of their participation in the trial.


CONCLUSIONS
This retrospective survey suggests that patient recruitment and consent for negligible- or minimal-risk clinical anesthesia research trials is appropriate when performed on the day of surgery.
