OBJECTIVES
To examine the feasibility of deploying a virtual web service for sharing data within a research network, and to evaluate the impact on data consistency and quality.
MATERIAL AND METHODS
Virtual machines (VMs) encapsulated an open-source, semantically and syntactically interoperable secure web service infrastructure along with a shadow database. The VMs were deployed to 8 Collaborative Pediatric Critical Care Research Network Clinical Centers.
RESULTS
Virtual web services could be deployed in hours. The interoperability of the web services reduced format misalignment from 56% to 1% and demonstrated that 99% of the data consistently transferred using the data dictionary and 1% needed human curation.
CONCLUSIONS
Use of virtualized open-source secure web service technology could enable direct electronic abstraction of data from hospital databases for research purposes.
目的
研究在研究网络内部署虚拟网络服务以共享数据的可行性，并评估其对数据一致性和质量的影响。
材料与方法
虚拟机封装了一个开源的、语义和句法可互操作的安全网络服务基础设施以及一个影子数据库。这些虚拟机被部署到8个协作式儿科重症监护研究网络临床中心。
结果
虚拟网络服务可在数小时内部署完成。网络服务的互操作性将格式不一致率从56%降至1%，并表明99%的数据使用数据字典能持续传输，1%的数据需要人工整理。
结论
使用虚拟化的开源安全网络服务技术能够直接从医院数据库中提取电子数据用于研究目的。
