Study of hypoactive delirium in critically ill patients: a scoping review
Objective To conduct a scoping review of relevant studies on hypoactive delirium in critically ill patients at home and abroad， to sort out the current status of hypoactive delirium， risk factors， assessment tools， timing of assessment， and intervention methods， etc.， so as to provide scientific basis for the prevention and management of hypoactive delirium in critically ill patients. Methods Based on the scoping review framework，a systematic search was conducted for relevant studies on hypoactive delirium in critically ill patients in Pubmed， the Cochrane Library，CINAHL，Web of Science，China Knowledge Network，Wanfang Database，China Biomedical Literature Database，and VIP database，with a timeframe of the construction of the database to December 2024. Data extraction and summary analysis of the included literature were performed by two researchers. Results 21 papers were eventually included. The prevalence of hypoactive delirium in critically ill patients ranged from 6.60% to 92.00%. Two assessment tools， ICU Ambiguity of Consciousness Assessment Method and Richmond Agitation-Sedation Scale，were mainly applied， and most of the studies assessed once a day，focusing on around 8:00-9:00 and 18:00. Factors influencing hypoactive delirium in critically ill patients included advanced age， diabetes，history of alcohol consumption， emergency surgery， and restraint use. Early integrated nursing interventions for patients were implemented. Conclusion Hypoactive delirium has a high incidence and serious adverse effects in critically ill patients，with complex and varied influencing factors， fewer types of assessment and diagnostic tools and lack of specificity，inconsistencies in the timing and frequency of assessment，and fewer intervention studies and a single design. It is recommended that healthcare professionals should deepen their research on assessment and diagnostic tools，assessment timing and intervention methods to provide a scientific basis for the prevention and management of hypoactive delirium.
