目的 研究我国农村居民年度医疗服务利用聚集性。方法 收集我国东、中、西部6个县（市）内的农村居民在县、乡、村三级医疗机构的就诊信息,运用Microsoft Excel编程技术,合并筛选居民个人年度的住院及门诊信息。分析我国农村居民的医疗服务利用聚集性程度及各个地区的水平差异。结果 农村居民年度医疗服务利用的人数及就诊单元量均随着就诊单元的增多逐渐减少;各个地区的平均就诊单元量介于5.22～12.17之间;集中指数均达到0.47以上,最高达0.62;总体上平均25%的人群利用了57.92%以上的医疗服务;高医疗服务利用人群以45～60岁居多。结论 不同地区农村居民年度医疗服务利用总体分布趋势基本一致;各个地区医疗服务利用均表现出较高的聚集性,且西部地区间的聚集性差异明显;性别年龄对医疗服务利用聚集性产生影响,高医疗服务利用以男性居多,45～60岁人群是高服务利用的主要人群。
