AIM: To determine cues to identify intensive care unit patients with distorted memories and related practices. DESIGN: Qualitative descriptive study. METHODS: Twenty nurses were included in semi-structured focus groups. Qualitative content analysis was conducted. RESULTS: Cues and nursing practices related to distorted memories emerged under the following categories: "Get to know daily life before admission," "Facial expressions and behaviour are different from usual," "Pay close attention to the treatment outcome," "Notice it after the fact," "Sharing patients' intensive care unit experiences" and "Creates a new life." Nurses tried to detect distorted memories by observing the patients' facial expressions, medication effects and delirium presence during their normal lives and treatments, while trying to understand the patients' intensive care unit experiences and provide care that promotes autonomous living. This study emphasizes the importance of support for reconstructing ordinary life through communication and rehabilitation, in addition to support for medical care for distorted memories.

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.
