2006—2015年PubMed数据库收录老年人尿失禁文献分析

目的了解老年人尿失禁研究文献的分布规律和研究热点。方法以美国国立图书馆的Pub Med数据库为文献信息来源,对2006—2015年收录的老年人尿失禁相关文献的年代分布、国家、发文语种、期刊分布和作者情况等进行统计分析,并对高频主题词进行聚类分析。结果共检索到老年人尿失禁相关文献3449篇,其中美国作者发文最多,为1313篇,占38.07%,中国位居第10位;研究文献以英语为主,汉语文献数量位居第5位;期刊分布则以《The Journal of Urology》发表老年人尿失禁文献最多,中文期刊均未进入核心区期刊;在发文量≥7篇的22名作者中,中国作者仅朱兰(北京协和医院妇产科)一位,列第4位。高频主题词聚类分析结果显示,老年人尿失禁文献的主要研究方向集中于尿失禁的外科手术治疗方法、病理生理学机制、流行病学研究、对尿失禁患者的护理、尿失禁的药物治疗方法 5个方面。结论尿失禁的手术治疗和药物治疗方法、病理生理学机制、护理和流行病学研究是近几年老年人尿失禁研究的热点,应引起国内外该领域临床和科研人员的重点关注。
