Best Evidence Summary for the Improvement and Management of Disorders of Consciousness in Patients With Severe Brain Injury

Background and purpose: The treatment effect of consciousness after brain injury is currently uncertain. Thus, this study aimed to retrieve the evidence from neurologists around the world on the management of consciousness disorders in patients with severe brain injury and evaluate and summarize the evidence, providing the guidance on the related management for clinicians.

Methods: Following the evidence summary report standard of Fudan University Center for Evidence-Based Nursing, clinical guidelines, expert consensuses, systematic reviews, and evidence summaries were systematically retrieved from UpToDate; BMJ Best Practice; Guidelines International Network; the Cochrane Library; Embase; PubMed; Sinomed; Web of Science; CNKI; WanFang database; American Academy of Neurology (AAN); American Congress of Rehabilitation Medicine (ACRM); European Academy of Neurology; and National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR). The publishing timeline for articles was limited from January 2017 to January 2024.

Results: Fourteen articles were finally identified. The 26 best pieces of evidence were recommended by inducting and integrating the evidence from these articles, covering the following seven aspects: consciousness assessment, multidisciplinary team, intervention in facilitating arousal, sensory stimulation programs, drug administration, rehabilitation program, and prevention of complications.

Conclusion: This study summarized the evidence of consciousness management in patients with brain injury, providing guidance for clinicians to develop and apply those interventions to improve the patient's clinical outcomes and quality of life. In addition, relevant factors such as the clinical environment and cooperation with the patient's family members should be evaluated and adjusted before applying such evidence. Future studies should focus on more targeted randomized clinical trials.
