摘要
目的 建立颌面部损伤严重度定级分类法 (maxillofacialinjuryseverityscaleclassifica tion ,MISSC)。 方法 回顾性研究 170 2例连续性颌面部损伤住院病人资料 ,依据伤情划定损伤程度为轻、中、重三种。采用AIS - 90版对各项损伤量化记分后 ,作因子分析及逐步判别分析 ,得到颌面部损伤严重程度评分分类函数 ,并进行回顾性、刀切法及前瞻性检验。 结果 因子分析将各类具有共线性的原始数据归类 ,得出的因子具有专科意义。逐步判别分析所得的分类函数 ,各项检验准确率均很高 :回顾性考核为 91.8% ,刀切法为 91.5 % ,前瞻性考核为 90 .1%。其中 ,前瞻性考核的灵敏度分别为 0 .92 2 (轻 )、0 .90 2 (中 )、0 .818(重 ) ,特异度分别为 0 .92 7(轻 )、0 .891(中 )、0 .995(重 )。 结论 MISSC法判别颌面部损伤的严重程度准确 ,漏判、误判率低 ,可用于临床伤情的分析研究。
Objective To present a maxillofacial injury severity scale classification (MISSC). Methods All 1 702 consecutive maxillofacial injury records were retrospectively studied. Based on the AIS-90 revision, every injury was scored. Then, 3 injury severity classification functions were obtained through factor an alysis and stepwise discrimination. The functions were tested retrospectively and prospectively with Jackknife method. Results Factor analysis synthesized those scores with multilinearities, which gave the new factors reasonable and professional explanation. The tests showed exactly high classification validity: retrospective test 91.8%, Jackknife method 91.5%, prospective test 90.1%; and the sensitivities of the prospective test were 0.922 (minor), 0.902 (moderate) and 0.818 (serious); the specificities of that were 0.927 (minor), 0.891 (moderate) and 0.995 (serious). MISSC also performed higher validity rate than the revised facial injury severity score (RFISS). Conclusions MISSC is a valid and reliable method in discriminating the maxillofacial injury severity, and can be used in clinical injury analysis.
