病例对照研究文献发表现状的分析研究--以中文护理学术期刊为例

目的：系统分析中文护理学术期刊病例对照研究的发表现状，为今后的研究提供参考。方法以中国知网、中国生物医学文献服务系统、万方数据知识服务平台和维普期刊资源整合服务平台为数据源，计算机检索发表在中文护理学术期刊上的病例对照研究，并采用文献计量分析法对纳入文献进行系统分析。结果共纳入文献77篇，分别发表在17种中文护理学术期刊上；文献数量总体呈增长趋势，文献内容涉及内科护理、外科护理和基础护理等11个护理领域，且有29．9％的文献获得基金支持；作者来自18个省、自治区和直辖市，主要分布在经济发达地区，研究单位以临床机构为主。结论病例对照研究逐渐受到国内护理研究者的重视，但研究数量总体偏少，应积极开展病例对照研究，将其应用于更广泛的护理研究领域。
