| 摘 要： | 目的了解影响重庆地区居民就诊服务的主要影响因素,满足更多居民卫生服务需求,提高卫生服务利用率.方法 针对重庆地区不同人群的影响因素,采取不同的卫生政策,构建影响居民就诊率的决策树模型.结果 调查的11 570名居民中,合计就诊人次为2 447人次,平均就诊次数2.1次,两周就诊率为21.15%(城市为12.58%、农村为29.19%),高于全国平均水平,而各年龄段的就诊率呈现中间低两端高的趋势,各年龄段就诊率差异有统计学意义(P<0.05);从决策树模型来看,此决策树共有17个节点,对应17条分类规则,树的根节点为职业类型,此变量对就诊率的影响最大,职业类型、年龄、居民类型、参保情况以及家庭年收入对居民就诊影响较大,且所选出的影响因素对不同人群的影响不同.结论 重庆地区居民就诊卫生服务利用相对较高,且不同人群的影响因素不同,因此,在制订卫生服务规划时应针对不同人群提出相应的卫生政策.
