Designing mobile-based tele dermatology for Indonesian clinic using user centred design: Quantitative and qualitative approach

This study was motivated by the increasing health services for skincare but limited availability of dermatologists in Indonesia, especially for remote areas. The health sector in Indonesia, including the dermatology and beauty sectors, has implemented technology to increase accessibility to health workers. Currently, there are several health facilities that have developed applications to support remote skin consultations (teledermatology) in Indonesia. This study aims to design a teledermatology application for clinics using a user-centered design (UCD) approach. UCD consists of understand context of use, specify user requirements, design and evaluate the prototypes. We used qualitative approach for understanding the problems, requirements and designing the low-fidelity prototype. Then, we used quantitative and qualitative approach for evaluating the prototypes. We collected quantitative data using an online questionnaire taken by 107 respondents and interviews with seven respondents. We found that teledermatology features, such as consultations and reminder notifications for self-care, are important to support dermatology activities. Our findings concern the teleconsultation feature, which still requires communication using WhatsApp for initial screenings. The quantitative evaluation resulted in a system usability scale score of 72.5, described as within the range of acceptability. Meanwhile, the post-study system usability questionnaire score reached an average value of 2.239, indicating that the usability of the application is good. The results of this study can be utilized by teledermatology application developers to improve their services.
