The use of instrumental tools for improving both the diagnostic accuracy and the prognostic soundness in patients with disorders of consciousness (DOC) plays an important role. However, the most recent international guidelines on DOC published by the American and the European Academies of Neurology and by the UK Royal College of Physicians contain heterogeneous recommendations on the implementation of these techniques in the clinical routine for both diagnosis and prognosis. With the present work, starting from the comparison of the DOC guidelines’ recommendations, we look for possible explanations behind such discrepancies considering the adopted methodologies and the reference health systems that could have affected the guidelines’ perspectives. We made a provocative argument about the need to find the most appropriate common methodology to retrieve and grade the evidence, increase the meta-analytic studies, and reduce the health policies that influence on the guidelines development that, in turn, should inform the health policies with the strongest scientific evidence.

仪器评估在意识障碍中的重要性：美国、欧洲和英国国际建议之间的比较

使用仪器工具来提高意识障碍 (DOC) 患者的诊断准确性和预后可靠性起着重要作用。然而，美国和欧洲神经病学学院和英国皇家内科医师学院最近发布的关于 DOC 的国际指南包含关于在临床常规诊断和预后中实施这些技术的不同建议。在目前的工作中，从比较 DOC 指南的建议开始，考虑到采用的方法和可能影响指南观点的参考卫生系统，我们寻找这种差异背后的可能解释。
