Résumé
Objective To analyze the correlation of discomfort experience and factual recollection (FR) in patients of intensive care unit (ICU). Methods Fifty-five ICU patients and 63 ward patients par-ticipated in the study. Standardized questionnaires were used to evaluate all patients" FR and the results underwent analysis. Results The prevalence of recollection of any type of discomfort in the ICU patients was 64%. The presence of an endotracheal tube, pain and hallucinations were identified as sources of dis-comfort.The median score for FR in the ICU patients was 7.25. The median score for FR in the ward pa-tients was 13.50. The difference between them was highly significant (t =3.34, P < 0.01 ). Logistic analysis revealed that discomfort, especially discomfort caused by the presence of an endotracheal tube, pain and hallucinations, was positively related to FR, 0R95%CI (1.2～2.1), P < 0.01. Conclusions The presence of an endotracheal tube, pain and hallucinations were most frequently reported as sources of discomfort in ICU patients and their memory was often impaired. FR and recollection of discomfort appear to be related significantly in ICU patients.
