Chronic pain in children and adolescents is often of multifactorial origin. The psychological stress of the patients is extremely high and is often influenced by excessive diagnostics. A pain diary as well as specific questionnaires concerning pain and depression can help to diagnose a chronic pain syndrome in the outpatient care.The treatment of chronic pain is based on a multimodal concept, which needs a multiprofessional team. The structure of outpatient treatment for this group of patients is sometimes still insufficient in Germany, which is why the treatment is nearly exclusively carried out in hospital. This is closely correlated with the success of treatment because otherwise the acquired strategies cannot be implemented into the routine use.
