Design and development of a registry system for primary vasculitis

The aim of this paper is to design and develop a registry system for Primary Vasculitis through a mobile and web application. The Primary Vasculitis (PV) is an orphan disease and a good start to help patients afflicted through a nationwide registry. This is one of the tasks of the recently-formed Philippine Vasculitis Study Group (PVSG). There have been attempts at creating a crude, Excel-based PV registry system by a few institutions but so far none is web-based nor applicable for nationwide consumption. There is also no existing mobile application, which are more widely used even by physicians due to its accessibility, for this purpose. The use of a mobile application for both offline/online data collection and a web application for a tabular view and download of the database is therefore proposed. The study created a more accessible, efficient, and secure way of collecting and collating patient data using the criteria endorsed by the American College of Rheumatology to pre-evaluate the patient during examination. AngularJS was the script language used for both mobile and web application. Ionic Framework and PouchDB were chosen to develop the mobile application for both Android and iOS platforms. CouchDB was used to synchronize data between web and mobile applications. The application's features are divided into four parts: (1) Authentication, (2) Data Collection, (3) Search, and (4) Data Synchronization. A mobile and web application registry system for Primary Vasculitis was created for the PVSG to be used at a national and possibly international level.
