Abstract

This study aimed to examine the relationship between memory status of and factors related to patients in the intensive care unit (ICU) using a cross-sectional study design. Participants were adult patients who were admitted to the general ICUs for more than 48 hours. One week after ICU discharge, a survey on memory distortion was conducted. Overall, 133 patients were included, of whom 51.1% reported distorted memories. Among them, 15.0% had memory loss; 48.1% had unrealistic experiences; 27.8% recalled confusion, panic, anxiety, and discomfort during their ICU stay; and 9% had traumatic experiences. Multiple logistic regression analyses revealed that memory loss was associated with an operation, and a significant association was observed between traumatic memory and pain. Opioid use may have a protective effect against memory loss. These results suggest the importance of relieving pain and preserving true memories during ICU treatment.
