摘要
[目的]应用分类树模型分析广州市预防接种门诊从业人员培训考核成绩的影响因素。[方法]2003～2005年对广州市预防接种门诊从业人员进行培训考核,用分类树模型分析1 824名学员考核成绩的影响因素。[结果]23期培训班考试成绩为61.0±12.1分,影响因素分析的分类树图中共有23个中间结,24个终结点。10分以上的预测因子依次是年龄(100分)、专业工作年限(45.84分)、是否中级职称(20.72分)、是否本科及以上(16.93分)、是否大专(13.99分)、是否初级(11.93分)。[结论]培训成绩维持在一个相对稳定的水平,培训的重点对象应该是年龄大于42.5岁而专业工作年限低者,可因材施教,专门为这部分人群安排相应内容及形式的培训。
[ Objective] To study the influencing factors of achievements of EPI inoculation practitioners by CART. [Methods] From 2003 to 2005, 1 824 EPI inoculation practitioners in Guangzhou were trained and classification and regression trees model were used to analyze influencing factors of achievements. [ Results] Of all 23 classes, the average score was 61.0±12.1 and there were altogether 23 internal nodes and 24 terminal nodes in the classification tree model. Predictive factors weighted over 10 score was age （100）, working years in profession （45.84）, whether middle technical post （20.72）, whether master degree or higher （16.93）, whether junior diploma （13.99） and whether primary technical post （ 11.93）, respectively. [Conlusions] Score stabled a relative level. Those who aged over 42.5 and worked for less years in EPI should be aimed at in particular and proper content and form of trainingshould be taken to them.
