 Founded in 1997, Health Dialog collaborates with the nonprofit Informed Medical Decisions Foundation to produce patient decision aids that seek to address unwarranted variation in healthcare and improve medical decisions by shared decision making.Shared decision making is a process with the aim of increasing patients' understanding of their conditions and treatment options, as well as their involvement in the choices that decide their care.82 percent of adults over the age of 40 have made a decision about having surgery, undergoing a screening test, or tasking a new medication in the past two years.
