At this moment when a clinician needs to conduct a study he will send allhis patients at various moments a questionnaire form. After retrieving theseforms the clinician will manually process all the data by hand. This is a time consuming job and could be automatized. During this project we created an application that automates this process. When using the developed application the only thing a clinician has to do is create forms, add patients and tell the system when a patient has to receive a form.
