Abstract
Background and purposeHealth 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 resultsUser-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. ConclusionThis 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.
Highlights
Hip and knee replacement are two of the most common elective operations, with over 100,000 of each performed annually in the UK [1]
JointCalc is a practical example of an effective software im plementation of a Health information systems (HIS), and represents the first comprehensive webbased patient decision support tool for joint replacement
The devel opers utilise existing knowledge of pitfalls common in HIS im plementations and leverage the solutions proposed by the scientific community to avoid them
Summary
Hip and knee replacement are two of the most common elective operations, with over 100,000 of each performed annually in the UK [1]. Between 10% and 20% suffer from moderate to severe long-term pain and a significant minority having severe complications that require repeat (revision) surgery or result in death [1]. Outcomes such as mortality and risk of revision surgery vary greatly according to patient factors, including age, gender, body mass index and co-morbidities [2,3]. This is supported by modern software production paradigms, including continuous integration/continuous development, agile and service-oriented architecture. The methods identified are shown to be applicable in the production of an effective HIS whilst aiding development efficiency
