In this paper is presented the use of value-based modeling, traditionally a business development tool, for the improvement of mobile health app design. The conceptual foundations for this work are design science, which is the scientific study and creation of artifacts, and convergence, which is a research method that in this case combines engineering with medicine. Relevant previous work done by the research team included the modeling of a case management system using process-based and information-based modeling techniques.
Value-based modeling represents actors who are exchanging with each other things of economic value, including service outcomes. The focus is on how value objects are offered, accepted, and exchanged in a network. Value-based models do not describe how transactions occur, but rather the net value of those transactions. This technique was applied to the design development of a mobile application system for the improvement of access to health services.
Significant value-based modeling was performed. These models highlighted the importance in healthcare delivery of effective value exchanges.
The results revealed a limitation on the net value of services delivery. These were related to constraints of time, cost, and responsibility. A design improvement was proposed: The development of an automated decision-making subsystem within the machine learning component of the app system. This subsystem would recommend between-visit micro adjustments to the plan of care based upon protocols established by the healthcare provider. Such would provide an agile response to the patient's changing needs as well as an amelioration to the challenges of access to services.
本文介绍了将传统上作为业务发展工具的基于价值的建模用于改进移动健康应用程序设计。这项工作的概念基础是设计科学，即对人工制品的科学研究和创造，以及融合，在这种情况下，融合是一种将工程学与医学相结合的研究方法。该研究团队之前所做的相关工作包括使用基于流程和基于信息的建模技术对一个案例管理系统进行建模。
基于价值的建模描述了相互交换具有经济价值的事物（包括服务成果）的参与者。重点在于价值对象在网络中是如何被提供、接受和交换的。基于价值的模型并不描述交易是如何发生的，而是描述那些交易的净值。这项技术被应用于一个移动应用系统的设计开发，以改善获得医疗服务的机会。
进行了重要的基于价值的建模。这些模型突出了有效价值交换在医疗服务提供中的重要性。
结果揭示了服务提供净值方面的一个限制。这些限制与时间、成本和责任的约束有关。提出了一项设计改进：在应用系统的机器学习组件内开发一个自动决策子系统。该子系统将根据医疗服务提供者制定的协议，为护理计划推荐就诊期间的微调。这将对患者不断变化的需求提供敏捷响应，并改善获得服务的挑战。
