Abstract

Objective To conduct a scoping review of the status on subsyndromal delirium in ICU patients at home and abroad，systematically elaborate the related concepts，assessment methods and influencing factors of this syndrome，and provide reference for ICU nursing staff to implement effective interventions，in order to reduce the incidence and adverse effects of subsyndromal delirium. Methods This study followed the framework of systematic literature review established by Arksey and O’Malley，the literature search was performed in PubMed，Web of Science，Embase，CINAHL，Cochrane Library，CNKI，Wanfang Database，VIP Database，China Biomedical Literature Database，and guideline network，with a time limit from database establishment to May 5，2024. Results A total of 27 articles were included，most were prospective studies. Three assessment tools were included，the Confusion Assessment Method of Intensive Care Unit（CAM-ICU），Intensive Care Delirium Screening Checklist（ICDSC） and Delirium Rating Scale（DRS-R98）. Higher incidence of subsyndromal delirium was observed in ICU patients. The main influencing factors included age，gender，APACHE II score，surgery，medication，environment，etc. Conclusion Medical staff should pay more attention to subsyndromal delirium，strengthen the identification and screening of its influencing factors，prevent it from progressing，so as to improve the quality of nursing and promote the early rehabilitation of patients.
