Approaches to the development of information systems in large health care institutions range from prototyping to conventional development of large scale production systems. This paper discusses the development of the SignOut System at Mount Sinai Medical Center, which was designed in 1997 to capture vital resident information. Local need quickly outstripped proposed delays for building a production system and a prototype system quickly became a production system. By the end of 2002 the New SignOut System was built to create an integrated application that was a true production system. In this paper we discuss the design and implementation issues in moving from a prototype to a production system. The production system had a number of advantages, including increased organizational visibility, integration into enterprise resource planning and full time staff for support. However, the prototype allowed for more rapid design and subsequent changes, less training, and equal to or superior help desk support. It is argued that healthcare IT systems may need characteristics of both prototype and production system development to rapidly meet the changing and different needs of healthcare user populations.
大型医疗机构中信息系统的开发方法多种多样，从原型开发到大规模生产系统的传统开发。本文讨论了西奈山医疗中心的交班系统的开发情况，该系统于1997年设计，用于获取住院医师的重要信息。当地的需求很快超过了构建生产系统的计划延迟，一个原型系统迅速变成了生产系统。到2002年底，新的交班系统建成，创建了一个真正的生产系统的集成应用程序。在本文中，我们讨论了从原型系统过渡到生产系统时的设计和实施问题。生产系统有许多优点，包括提高组织可见性、集成到企业资源规划以及有全职人员提供支持。然而，原型系统允许更快速的设计和后续更改，培训较少，并且提供同等或更好的帮助台支持。有人认为，医疗信息技术系统可能需要同时具备原型开发和生产系统开发的特点，以便快速满足医疗用户群体不断变化的不同需求。
