Memories of colonoscopy: a randomized trial
Open accessAbstract
Patients' memories of the past may influence their decisions about the future, yet memories are imperfect and susceptible to bias. We tested whether a memory failure observed in psychology experiments could be applied in a clinical setting to lessen patients' memories of the pain of an unpleasant medical procedure. We studied consecutive outpatients undergoing colonoscopy who were medically stable, mentally competent, and able to speak English (n=682). By random assignment, half the patients had a short interval added to the end of their procedure during which the tip of the colonoscope remained in the rectum. Pain during the procedure was measured with a ten point intensity scale. Memory following the procedure was measured using both a rating scale and a ranking task. Randomization resulted in two similar groups. As theorized, patients who underwent the extended procedure experienced the final moments as less painful (1.7 vs. 2.5 on a ten point intensity scale, P<0.001), rated the entire experience as less unpleasant (4.4 vs. 4.9 on a 10 cm visual analogue scale, P=0.006), and ranked the procedure as less aversive compared to seven other unpleasant experiences (4.1 vs. 4.6 with eight as the worst, P=0.002). Rates of returning for a repeat colonoscopy (median duration of follow-up 5.3 years) averaged 50.4% and were slightly higher (odds ratio=1.41, P=0.038) for those who underwent the longer procedure controlling for prior colonoscopy, procedure indications, and abnormal findings. Memory failures observed in experimental conditions can be found in clinical settings involving awake patients and may offer opportunities for improving patients' willingness to undergo future unpleasant medical procedures.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
