Background and purpose

Health information systems (HIS) are expected to be effective and efficient in improving healthcare services, but empirical observation of HIS reveals that most perform poorly in terms of these metrics. Theoretical factors of HIS performance are widely studied, and solutions to mitigate poor performance have been proposed. In this paper we implement effective methods to eliminate some common drawbacks of HIS design and demonstrate the synergy between the methods. JointCalc, the first comprehensive patient-facing web-based decision support tool for joint replacement, is used as a case study for this purpose.

Methods and results

User-centred design and thorough end-user involvement are employed throughout the design and development of JointCalc. This is supported by modern software production paradigms, including continuous integration/continuous development, agile and service-oriented architecture. The adopted methods result in a user-approved application delivered well within the scope of project.

Conclusion

This work supports the claims of high potential efficiency of HIS. The methods identified are shown to be applicable in the production of an effective HIS whilst aiding development efficiency.

JointCalc：基于网络的个性化患者决策支持工具，用于关节置换。

背景和目的

健康信息系统 (HIS) 有望在改善医疗保健服务方面有效且高效，但对 HIS 的经验观察表明，大多数在这些指标方面表现不佳。对 HIS 性能的理论因素进行了广泛研究，并提出了缓解不良性能的解决方案。在本文中，我们实施了有效的方法来消除 HIS 设计的一些常见缺点，并展示了这些方法之间的协同作用。JointCalc 是第一个面向患者的综合性基于网络的关节置换决策支持工具，被用作此目的的案例研究。

方法和结果

以用户为中心的设计和彻底的最终用户参与贯穿于 JointCalc 的设计和开发过程中。这得到了现代软件生产范式的支持，包括持续集成/持续开发、敏捷和面向服务的架构。采用的方法可以在项目范围内很好地交付用户认可的应用程序。

结论

这项工作支持了 HIS 的高潜在效率的说法。所确定的方法被证明适用于生产有效的 HIS，同时有助于提高开发效率。
