A study on reliability and validity of Chinese version of the Denver Emergency Department Trauma Organ Failure Score / 中国实用护理杂志

ABSTRACT

Objective To investigate Chinese version of the Denver Emergency Department Trauma Organ Failure Score and examine its reliability and validity. Methods The original Denver ED TOF Score was translated into Chinese and back translated and modified for cultural adaptation according to guidelines.A survey using Chinese version of the Denver ED TOF Score was conducted on 313 trauma patients in order to verify its reliability and validity. Results Factor analysis extracted three common factors, which explained 63.327% of variance of the total scale, and each item had high factor loading quantity(>0.4).The item-level content validity index of Chinese Denver ED TOF Score were 0.80 to 1.00. and the scale-level content validity index was 0.93.Its sensitivity was 84.0% and specificity was 81.6% when score of Chinese Denver ED TOF Score was two or more. The area under receiver operator characteristic curve for Chinese Denver ED TOF Score prediction of multiple organ failure was 0.878 (95% CI 0.812-0.944, P<0.01). The Chinese version of Denver ED TOF Score had higher internal consistency, with Cronbach Alpha coefficient 0.738 and intra- class correlation coefficients 0.994. Conclusions The Chinese version of Denver ED TOF Score has a high reliability and validity, which could be used as a tool for predicting and diagnosing development of MOF in adults following trauma.
