To increase understanding of the information needs and use of public health practitioners.
From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services.
We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants.
The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice.
增进对公共卫生从业者信息需求及信息使用情况的了解。
2005年6月至2006年5月期间，该图书馆为两个县的18名从业者提供了公共卫生信息资源课程，通过量身定制的门户网站提供对图书馆授权电子资源的访问以及咨询服务。
我们结合了门户网站的使用统计数据、培训及跟踪参与者期间收集的自我报告和观察数据。
该项目的数据表明，授权信息资源和服务的使用频率不高，但范围广泛。少数用户处于使用范围的高端，但一篇高质量文章的一次使用就可能对政策决策产生重大影响。时间和其他职责往往会限制为循证决策检索和使用资源，信息专员或高级用户模式可能比培训所有从业者将检索融入其工作流程更为合适。本研究表明：（i）循证公共卫生实践需要无缝且广泛的信息获取；（ii）当前现有的拼凑式安排无法支持使用水平，也未考虑到公共卫生实践信息需求的时间限制。
