Design of Application Framework for Vital Sign Monitoring and Remote Doctor Consultation

Health services entail face-to-face interactions between patients and physicians, whereby the patient reports the symptoms they are experiencing, and the doctor examines the patient's vital signs. In Indonesia, a doctor consultation system is presently accessible to the public. However, a vital sign monitoring system, which is linked to medical devices used in measuring patient vital signs, is yet to be established in the country. To address this, our research endeavours to establish an application framework for telehealth that encompasses doctor consultation features and the ability to remotely check a patient's vital signs. The application framework serves as a software foundation that can be transformed into finished software. Additionally, it ensures consistency in the produced product model during development. The analysis and design of the application framework employ the Feature-Oriented Domain Analysis (FODA). Typically, FODA is used to analyze a single domain, but this study applied it to two different domains. Our research findings reveal 14 primary features and 45 sub-features that must be incorporated into the application framework. The framework comprises 16 frozen and six hot spots, where the Strategy, Observer, and Filter design patterns are implemented. These outcomes can guide software developers in developing web-based Telehealth remote doctor consultations and vital sign monitoring.
