1634. A Mobile Application for Management and Surveillance of Vector-borne Diseases in Cali, Colombia: An Evaluation of Usability and Acceptability in a Hospital Setting

BACKGROUND: Vector-borne diseases are a public health problem in Colombia, an area that has become hyperendemic for dengue virus. This situation has been aggravated by the introduction of other arboviruses such as chikungunya and Zika in the last 3 years. Mobile health (mHealth) offers new strategies for strengthening healthcare and surveillance systems. A large number of mHealth tools are available; however, very few have been evaluated regarding usability and acceptability. This study aimed to evaluate the usability and acceptability of a mobile application, FeverDX, as a support tool in the management of patients with febrile syndrome and suspected vector-borne infection by general practitioners from Colombia. METHODS: The usability and acceptability of FeverDX were evaluated using the modified version of the Mobile Application Rating Scale (uMARS). The evaluation included aspects of content, user engagement, functionality, user-interface design, impact, and subjective quality. RESULTS: Between December 2016 and January 2017, a total of 20 general practitioners evaluated FeverDX. Seventy-five percent of the evaluators reported being aware of the Colombian Ministry of Health guidelines for diagnosis and management of arboviruses. 80% of evaluators partially or completely agreed the application information agreed with management guidelines. On uMARS scale, FeverDX excelled regarding impact (median = 5/5, IQR = 5–5); functionality (5/5, 4.8–5); and information and scientific basis (4/5, 4-4). FeverDX scored well regarding user feedback (median = 4/5, IQR = 4–4.5); design and esthetics (4/5, 4–4.3); and subjective assessment of quality (4.5/5, 4.3–4.8). CONCLUSION: Despite a large number of mHealth tools available, the literature lacks evaluated and evidence-based mobile technology. Applying Information and Communications Technologies in health areas can strengthen care processes and facilitate the detection and reporting of reportable surveillance diseases. Assess the usability and acceptability of mobile health applications increases the reliability of these technologies. The mobile app, FeverDx, can improve adherence to guidelines for management and prevention of prevalent diseases. DISCLOSURES: All authors: No reported disclosures.
