The tools include educational material, use of (e.g. texts, images, movies, web-links) and interactive components (e.g. ability to report steps per day and symptoms with feedback) adapted to the different stages of the disease. The section directed towards health care professionals includes tools that aim to improve the knowledge, attitudes and confidence in providing evidence based health promotion interventions. The tools include easily accessible knowledge and material (e.g. movies, screening tests, images, power point presentation for patient education and exercise programs).The control group will be recruited from the same health care units among listed patients with no planned visit within the 3 month intervention period. The control group will not receive any intervention.
