摘要
医疗电子病历系统作为中国医疗信息化建设的核心,关注其采纳与扩散机理,对推进医疗卫生信息化建设,以及实现有意义地使用具有重要的理论和实践意义。基于云南省222家医院信息化建设的调研数据,运用半参数生存分析法即Cox回归模型探讨医院采纳电子病历系统的影响因素及扩散机理。研究表明,教学状态、医院规模和建院时间均为有利因素,即这三个因素积极促进医院采纳电子病历系统;时间×规模为不利因素,即它对医院采纳电子病历系统有负向影响;地理位置在分层和删减样本的模型分析中均表现为不利因素;医院等级影响并不明显。
As the core and key of medical information construction, it has an important theoretical and realistic significance to pay an attention to the adoption and diffusion of electronic medical records. Based on the survey data of information construction of 222 hospitals in Yunnan province, the semi parametric survival analysis technique namely Cox regression model was applied to study the influential factors and diffusion mechanism on the adoption of electronic medical records in hospitals. The results show： （1） teaching status, hospital size and hospital age are all protective factors, namely actively promoting the adoption of electronic medical records for hospitals ; （2） hospital size x hospital age is an adverse factor, namely exerting a negative impact on hospitals to adopt electronic medical records; （3 ） geographical location is characterized by an adverse factor in Cox model analysis of the stratified and cut sample; （4） the influence of hospital level is not obvious; （5 ） the dynamic trend of the adoption of electronic medical records for hospitals is also revealed.
