Two key network architecture reports have been completed as part of the overall project: The overall objective of this project is to design a scalable, distributed health information network that will support secure data analyses on the risks and benefits of therapeutics. Objectives and Goals of the Distributed Research Network Project Only a coordinated, well-supported, and step-wise approach is likely to garner the support necessary to build a viable and sustainable distributed research network. This phased approach will enable research to be conducted in parallel with the development of the network, which will in turn help to inform continued development and improvements. Additional phases would expand the network by adding new data sources, accommodating new data types, and expanding network functionality. In general, the first phase should focus on the most commonly-used and best understood data types, rely on simple technical requirements, and include targeted functionality. The report includes lessons learned from administrative, governance, technical, and research components of the project, and it emphasizes the scalability of the system.Ī phased, systematic approach to implementation is recommended for creation of a viable distributed research network. The current report serves as a blueprint to guide future development of a distributed research network based on the experience of designing and testing a network prototype. Issues such as security, proprietary, legal, privacy, and cost will present substantial challenges to implementation and maintenance of a network. ![]() ![]() ![]() Finally, a network should support both simple, menu-driven querying and complex queries using customized analysis code.Ī large-scale distributed research network will require a substantial investment in administrative and governance infrastructure along with the investment in information technology. A network should also support a variety of study types, including observational studies, quasi-experimental studies, clinical trials, and registries. At the highest level, a functioning distributed research network should be able to securely perform the following tasks: (1) distribute queries through network software (2) execute the queries against the local data and (3) return aggregated results to the end-user. A distributed network is preferred over a centralized system because it allows data holders to maintain physical and logical control over their data. A Department of Ambulatory Care and Prevention, Harvard Medical School and Harvard Pilgrim Health Care.Ī distributed research network with an efficient, reusable infrastructure to assemble and analyze routinely collected healthcare data and related information could assist AHRQ by providing the means to rapidly generate reliable information about utilization and outcomes of care needed to support decision making by patients, providers, and policy-makers.
