Diverse interventions have been effective in the management and treatment of patients with functional disorders. Care recommendation letters for the GPs have both helped reduce the patients' use of health care and improved their level of physical functioning. Randomized controlled trials (RCT) have shown that cognitive behavioral treatment (CBT) has effect on specific patient groups with functional disorders. Through a combination of cognitive behavioral therapy, social counselling and recommendation letters, it is possible to offer patients with chronic functional somatic symptoms a presumably effective and cost-effective treatment.
