Digital health sciences library (DHSL) evaluation involves studying the usage of the DHSL by individuals as well as populations. The purpose of this study was to evaluate trends in overall usage of a DHSL as part of a process of continuous quality improvement in order to learn how to enhance a DHSL in order to meet its users' needs better.
Web server log file analysis was performed on a prototype DHSL, the Virtual Hospital, using two log file analysis programs on data from the month of February over four consecutive years, 1995 to 1998.
Overall DHSL usage increased between 1995 and 1997 and leveled off in 1998. Fifteen percent of usage came from countries outside the United States. A broad spectrum of medical information for health care providers and patients was accessed and centered around specialty medical information.
To be of optimal assistance to users, DHSLs should (1) contain a broad base of information on common and uncommon medical problems, (2) accommodate the needs of the significant percentage of users that are international through content translation and mirroring, and (3) ensure they are indexed and catalogued in the major Web search engines and Web general and medical indices so they can be easily found by users.
数字健康科学图书馆（DHSL）评估涉及研究个人以及人群对DHSL的使用情况。本研究的目的是评估DHSL的整体使用趋势，作为持续质量改进过程的一部分，以便了解如何改进DHSL以更好地满足用户需求。
使用两个日志文件分析程序，对一个DHSL原型——虚拟医院，在1995年至1998年连续四年中2月份的数据进行网络服务器日志文件分析。
1995年至1997年期间，DHSL的整体使用量有所增加，并在1998年趋于平稳。15%的使用量来自美国以外的国家。访问了广泛的医疗信息，供医疗保健提供者和患者使用，且以专业医疗信息为中心。
为了向用户提供最佳帮助，数字健康科学图书馆应：（1）包含关于常见和罕见医疗问题的广泛信息基础；（2）通过内容翻译和镜像来满足相当比例的国际用户的需求；（3）确保它们在主要的网络搜索引擎以及网络通用和医学索引中进行索引和编目，以便用户能够轻松找到。
