Extensible System for Disseminating Polysomnography Data

描述（由申请人提供）：提出了一种用于传输和存储多导睡眠图数据的创新系统，旨在创建一个更有效和全球连接的系统，用于共享、存档和远程访问睡眠研究。该系统将包括一个开放文件规范、一个网络传输协议、将现有软件方法转换为开放标准所需的工具，以及建立一个具有Web 2.0在线协作能力和分布式工作流服务的集中睡眠记录数据库。文件规范（OpenXDF）基于XML，并且已经由睡眠社区中的知名公司和研究机构进行了推广和beta测试。成立了一个组织和倡议（OpenXDF倡议），带头在研究人员、临床医生和工程师之间共同努力，开发一种可互换的PSG数据格式，用于商业上可用的NPSG采集软件系统，以推进多导睡眠图和神经病学领域。该规范优于现有的开放文件格式，因为它是可扩展的，非常倾向于在web环境中使用，并且能够集成到现有的商业系统中。OpenXDF格式将根据同行评审期间收到的建议和从该组织网站收集的反馈继续进行微调。软件开发和文件转换工具将提供给第三方，以便将文件格式轻松集成到他们现有的PSG软件架构中。还将开发一种网络传输协议，允许连接到TCP/IP网络（包括因特网）的任何计算机访问OpenXDF格式的睡眠研究。病人的隐私将通过访问控制和强加密来保护。在压缩技术和数据插值方面的研究方法将被用于在客户端组装文件，尽管网络延迟，以便睡眠研究可以无缝地审查和使用低成本的互联网连接远程分页。对Web 2.0脚本技术的研究将有助于开发和支持网络服务器，为订阅会员托管NPSG研究数据库，并允许在线协作，专家之间的开放对话，以及在在线门户中共享记录，评分信息和规范的PSG数据。数据库和分析后端软件将由一个基于web的应用程序封装，该应用程序通过动态图形界面将记录、所有注册会员和计分员连接起来。这个创新的系统将鼓励睡眠社区成员之间的公开参与，并在许多评分者之间实时生动地分享广泛的睡眠记录信息。完整的项目将基于先进的开发技术和概念，包括解释语言、ATL、PHP、AJAX和XML。公共卫生相关性：由于开放市场上可互换的多导睡眠图数据和研究工具的可用性增加，由此产生的系统将改善卫生保健并推进睡眠医学的研究。医院和诊所的总体成本负担将减少，因为重点将从涉及大量资本投资的设备销售转向基于服务的商业模式，只需少量初始存款和NPSG数据库访问、审查、评分和分析功能的月费。

DESCRIPTION (provided by applicant): An innovative system for the transmission and storage of polysomnography data is proposed with the aim of creating a more efficient and globally connected system of sharing, archiving, and remotely accessing sleep studies. The system will include an open file specification, a network transmission protocol, the tools needed to translate existing software approaches into the open standard, and the establishment of a centralized sleep record database with Web 2.0 online collaboration capability and distributed workflow services. The file specification (OpenXDF) is based on XML and has been promoted and beta tested by prominent companies and research facilities in the sleep community. An organization and initiative (OpenXDF Initiative) was created to spearhead a combined effort between researchers, clinicians, and engineers to develop an interchangeable PSG data format that is used on commercially available NPSG acquisition software systems to advance the fields of polysomnography and neurology. The specification is superior to existing open file formats in that it is extensible, heavily biased towards use in a web environment, and capable of being integrated into existing commercial systems. The OpenXDF format will continue to be fine-tuned based on the suggestions received during peer reviews and the feedback compiled from the organization's website. Software development and file conversion tools will be made available to third parties for easy integration of the file format into their existing PSG software architectures. A network transmission protocol will also be developed which will allow access to sleep studies in the OpenXDF format from any computer connected to a TCP/IP network, including the Internet. Patient privacy will be preserved using access controls and strong encryption. Research methods in compression techniques and data interpolation will be employed to assemble the file on the client-end despite network latencies so that sleep studies may be seamlessly reviewed and paged remotely using low cost Internet connections. Research into Web 2.0 scripting technology will aid the development and support of a networked server hosting a database of NPSG studies to subscribed members and allowing online collaboration, open dialog among experts, and the sharing of records, scoring information, and normative PSG data within an online portal. The database and analysis back-end software will be encapsulated by a web-based application linking the records, all registered members, and the scorers with a dynamic graphical interface. The innovative system will encourage open engagement among associates of the sleep community and the vivid sharing of extensive sleep record information over many scorers in real-time. The complete project will be based on advanced development technology and concepts including interpreted languages, ATL, PHP, AJAX, and XML. PUBLIC HEALTH RELEVANCE: The resulting system will improve health care and advance research in sleep medicine due to the increased availability of interchangeable polysomnography data and research tools in the open market. The overall cost burden on hospitals and clinics will be reduced due to a shift in focus from equipment sales involving a large capital investment to a service-based business model with small initial deposits and monthly charges for NPSG database access, review, scoring, and analysis features.
