One of the modern forms of mutual doctor-patient collaboration is so-called 'shared decision-making'. This type of mutual relationship has a relatively short history. It began to be written about in the 1980s. In this trend, the doctor-patient relationship is based on increasing the patient's medical knowledge and having more influence on treatment decisions. Both patient and doctor share information and insights about treatment options. Decisions are made jointly based on both people agreeing on a course of action. This doctor-patient relationship requires a lot of effort on both sides, but also offers new therapeutic possibilities.
