Abstract
There is increasing demand to improve the quality and efficiency of healthcare delivery. Mobile health self-reporting can play a vital role here, provided that user acceptance can be achieved. We developed a mobile health reporting app for patients suffering from inflammatory bowel diseases and tested its acceptance, perceived usefulness and usability in a field trial with 35 patients over a period of eight weeks. Participants selected were already accustomed to filling in questionnaires about their health and well-being (albeit less frequently and post-hoc). Therefore we designed and implemented an interface emulating this form of interaction as closely as possible. This approach proved to be successful: our participants in the field study attested to the feasibility of this approach as indicated by the data presented here. With our example, we can show that for an effective transition to electronic/mobile systems, it should be possible to minimize the gulfs of execution and evaluation.
