目的采用主成分分析法对不同地区医院开展的控烟工作进行综合评价,探讨运用主成分分析法进行综合评价的可行性,为更好地开展无烟医疗机构创建提供依据。方法采用分层随机抽样的方法,在7个项目省共选择210家医院作为研究对象,在回顾文献及咨询专家的基础上确定医院的控烟工作指标,对指标收集数据进行主成分分析并根据主成分分析的结果计算不同地区的综合评分。结果医院控烟工作开展指标主要提取了两个主成分,分别反映了医院禁烟制度及开展的工作、领导控烟意愿及对病人开展的工作;评分结果显示,上海、浙江等省市大部分地区医院控烟工作综合得分较高,江西、黑龙江等省市医院得分相对较低。结论运用主成分分析法对医院的控烟工作进行综合评价,可以消除指标间的共线性,避免人为因素影响,具有较强的全面性和客观性。
Objective To evaluate the feasibility of tobacco control in hospitals in different areas by using principal component analysis and to explore the feasibility of using principal component analysis to conduct comprehensive evaluation so as to provide a basis for better establishment of smoke-free medical institutions. Methods By stratified random sampling method, a total of 210 hospitals were selected as research objects in 7 project provinces. Based on reviewing the literature and consulting experts, the indicators of tobacco control in hospitals were determined. The principal component analysis The result of component analysis calculates the overall score of different regions. Results There were two principal components extracted from the index of tobacco control work in hospitals, which respectively reflected the banning of smoking and the work carried out by the hospital, the willingness to lead tobacco control and the work on patients. The results showed that smoking control in most hospitals in Shanghai, Zhejiang and other provinces Comprehensive work scores higher, Jiangxi, Heilongjiang and other provincial hospitals score relatively low. Conclusion The principal component analysis of the comprehensive evaluation of tobacco control work in hospitals can eliminate the collinearity between indicators, to avoid human factors, with strong comprehensiveness and objectivity.
