EpiConcept makes customized information systems based upon its in-house created Voozanoo platform. Many databases are in fact, simple questionnaires that could be constructed by non-IT specialists. Thus a “limited functionality” version of Voozanoo was needed. The challenge of Wepi was to create a tool that could respond to the need for non-IT people to create and disseminate their own simple questionnaires.
The epidemiological standard up to now has been the EpiData product but it requires training and it is a stand-alone application installed on a single computer. By leveraging the connectivity of the Internet, Wepi is available to anyone who has a web browser and further, data can be filled in by multiple people in multiple locations. With disease outbreak investigations requiring quick data collection, we responded to this need by including a mobile data collection method. We integrated the already existing open source Open Data Kit application which allows one to fill out his/her questionnaires on a phone or tablet without an Internet connection.
Who uses it?
We have public health professionals and epidemiologists in mind. They are not software developers and don’t have the time to be. This web application allows them to simply log-in, type (or paste in with one single action) their questions and then adjust them for the correct variable types (whole numbers, decimals, dates, text, multiple choice). In the case of a disease outbreak, such as a food-borne disease outbreak, responses to traditional paper questionnaires can be entered into this questionnaire system or the questionnaire can be filled out on a tablet as the interviewer is speaking with people involved in the outbreak. Since the results are stored on-line, they can be analysed by experts in real time regardless of their location.
