Recall of informed consent is not affected by the timing of obtaining informed consent before any procedure.

Evidence: A prospective, randomized study enrolled 60 patients scheduled for colonoscopy or esophagogastroduodenoscopy. All the patients received informed consent 24-72 hours or immediately prior to the procedure. Follow-up was done 1-3 days post-procedure. No statistically significant difference was noted in recall of informed consent or the individual elements of informed consent, including indication, risks, benefits, alternatives, between the two study groups. The study thus concluded that recall of informed consent is similar irrespective of the timing of obtaining informed consent before endoscopic procedures.
