Going digital: opportunities and barriers in the use of technology for health research.

Digital health refers to the use of novel information com-munication technologies in healthcare. The use of these technologies could positively impact public health and health outcomes of populations by generating timely data, and facili-tating the process of data collection, analysis, and knowledge translation. Using selected case studies, we aim to describe the opportunities and barriers in the use of technology applied to health-related research. We focus on three areas: strategies to generate new data using novel data collection methods, strategies to use and analyze existing data, and using digital health for health-related interventions. Exemplars from seven countries are provided to illustrate activity across these areas. Although the use of health-related technologies is increasing, challenges remain to support their adoption and scale-up -especially for under-served populations. Research using digital health approaches should take a user-centered design, actively working with the population of interest to maximize their uptake and effectiveness.
