"Tertiary prevention aims to soften the impact of an ongoing illness or injury that has lasting effects. This is done by helping people manage long-term, often-complex health problems and injuries (e.g. chronic diseases, permanent impairments) in order to improve as much as possible their ability to function, their quality of life and their life expectancy. Examples include: cardiac or stroke rehabilitation programs; chronic disease management programs (e.g. for diabetes, arthritis, depression, etc.); support groups that allow members to share strategies for living well; and vocational rehabilitation programs to retrain workers for new jobs when they have recovered as much as possible."
