Motivation for patients after obesity-related surgery


The mHealth app MIMOTI (“mini Motivation”) supports the postoperative bariatric treatment process. The focus is on daily exercise and raising health awareness.


The app was used productively in May 2016 as part of a clinical study by Inselspital Bern entitled “The impact of daily physical activity on weight loss after bariatric surgery”. The study investigates the extent to which physical activity has an effect on well-being after surgery. The patients record their weight and measure their steps with a pedometer. These data are stored in their MIDATA account. Patients can use a mobile app to track their progress and supplement these data with a self-assessment of their well-being. With the consent of the participants, these data will be used in pseudonymized form for the study under the direction of Dr. Philipp Nett.

The high number of patient entries (on average 3 per day) shows that reporting with a personalized progress report increases the motivation for increased exercise. Not only because of the good acceptance and the positive feedback on the MIMOTI App, patient care in this form should be pursued further. Gamification, the additional recording of values, such as nutrition or medication, as well as the inclusion of laboratory values, could represent meaningful further development steps for MIMOTI.

In September 2016, the app and its developers, Adrian Wyss and Aline Zaugg, were awarded the “Prix d’excellence” for outstanding medical informatics projects in the “Best Implementation” category. The prize is awarded as part of a partnership between the Bern University of Applied Sciences and the Biel Hospital Centre.

The MIDATA data platform enables members of the public to compile their health records in a secure personal account free of charge and to determine if and how they are used in research projects. In this way, they can act as «citizen scientists», making an active contribution to medical research.
MIDATA serves as a data repository for its members and other participating members of the public. It is a non-profit cooperative facility that operates without offering financial incentives, similarly to blood donation services, for instance. The account holders are not paid for their intentional and voluntary «data donation». The revenue generated from the integration of their data into a scientific study is reinvested in the services offered on the platform and in a variety of smaller research projects. Start-ups, IT service providers and research groups can use the platform to offer mobile apps, such as health apps or apps for treating and monitoring patients with chronic illnesses. MIDATA is currently being used in a number of scientific health projects. In one particular project being conducted at University Hospital Zurich, for example, multiple sclerosis patients are being included in a study into the effect of treatments, which uses a tablet app to test their cognitive and motor skills. A further project, currently in development at ETH Zurich, will look at different training methods and the impact they have on muscle growth. More and more projects are being run that are directed at a wide section of the population and are of value to many – as is the case with the «Ally Science» project.


The Adipositaszentrum at Bern University Hospital is devoted to the treatment of overweight and obesity, using conservative and/or newest interventional care and therapies.
The Adipositaszentrum follows a patient-centric approach. The large knowledge and capabilities of University Hospital Bern are readily accessible for all patients.
