Objective:To discuss value of AIS-ISS trauma score and craniocerebral injury index(CCⅡ) on the self-help ability of patients with craniocerebral injury. Methods:132 cases of postoperative patients with craniocerebral injury were retrospectively analyzed and divided into good self-care ability group(KPS 51-100) and poor self-care ability group (KPS 0-50) according to Karnofsky performance scale(KPS). The correlation between KPS and CCⅡ, as well as AIS-ISS was analyzed; Area under the receiver-operating characteristic curve (ROC) of the two scoring methods was drawn, the area under curve was calculated, and then evaluating criteria was confirmed based on sensitivity and specificity. Results:CCⅡ of good self-care ability group was higher than that of thepoor self-care ability group,AIS-ISS was lower than that of the poor self-care ability group, the difference was statistically significant (P<0.05). There was a significant positive correlation between CCⅡ and KPS of 6 months after discharge (r=0.597, P<0.01), the AIS-ISS was negatively correlated with KPS of 6 months after discharge (r=-0.627, P<0.01). The area of the ROC curve of that CCⅡ and AIS-ISS predicting KPS of 6 months after discharge on patients with craniocerebral injury were respectively 0.748 and 0.802; the results showed when CCⅡwas ≥ 2.5 and AIS-ISS was ≤ 14.5 on admission, KPS of 6 months after discharge was better. Conclusion:AIS-ISS trauma score and CCⅡ are both predictive for KPS of 6 months after discharge on patients with craniocerebral injury, but AIS-ISS is more closely related to self-care ability and more predictive.
