The main objectives will be to explore what participants considered to be the key unmet needs in diagnosis, treatments and follow-up and their hopes for the future, and compare it with results of focus groups (FG) we performed in 2014. Furthermore, we aim at conducting a survey to assess the overall levels of patientreported concerns, needs and expectations in our Swiss UC population after 10 years.
