BackgroundThe Glasgow Coma Scale (GCS) is currently the most widely used scoring system for comatose patients. A decade ago, the Full Outline of Unresponsiveness (FOUR) score was devised to better capture four functional aspects of consciousness (eye, motor responses, brainstem reflexes, and respiration). This study aimed to validate the Chinese version of the FOUR score in patients with different levels of consciousness.MethodsThe study had two phases: (1) translation of the FOUR score, and (2) assessment of its reliability and validity. The Chinese version of the FOUR score was developed according to a standardized protocol. One hundred-twenty consecutive patients with acute brain damage, admitted to Nanfang Hospital (Southern Medical University, Guangdong, China) from November 2014 to February 2015, were enrolled. The inter-rater agreement for the FOUR score and GCS was evaluated using intraclass correlation coefficient (ICC). Receiver operating characteristic (ROC) curves were established to determine the scales' abilities to predict outcome.ResultsThe rater agreement was excellent both for FOUR (ICC = 0.970; p < 0.001) and GCS (ICC = 0.958; p < 0.001). The FOUR score yielded an excellent test-retest reliability (ICC = 0.930; p < 0.001). Spearman's correlation coefficients between GCS and the FOUR score were high: r = 0.932, first rating; r = 0.887, second rating (all p < 0.001). Areas under the curve (AUC) for mortality were 0.834 (95 % CI, 0.740-0.928) and 0.815 (95 % CI, 0.723-0.908) for the FOUR score and GCS, respectively.ConclusionsThe Chinese version of the FOUR score is a reliable scale for evaluating the level of consciousness in patients with acute brain injury.
