The effect of hypnotic intervention for the refractory chronic pain patients was examined along with the process of patients' selection and their psychological characteristics. The total 596 visit patients in the first year were statistically examined concerning duration of pain, scores of psychological distress (Hospital Anxiety and Depression Scale) and disability (Pain Disability Assessment Scale) at the initial visit and the treatment outcome at the end of the first year. The duration of chronic pain was significantly related to disability but not to psychological distress at the initial visit. At the end of the first year of multidisciplinary pain treatment, 44% of total patients were under treatment, 19% finished treatment (10% evidently improved and 9% accepted their pain), 12% were referred and 25% dropped out. The group of patients who were evidently improved was not different concerning the duration of pain, but significantly less anxious, less depressed and less disabled at the initial visit than the other groups. Among the 261 patients under treatment, 33 patients (5.6% of total patients) were introduced into individual psychological interventions in consideration of 1) poor outcome in pharmacological and physical treatments, 2) unstable treatment relationship and marked pain behaviors, 3) obvious psychological distress, 4) event-related fluctuations in pain. They were significantly more anxious and depressed at the initial visit, than those who were not introduced to psychological intervention. Multiple bio-psycho-social factors were identified; tender points in 21 patients (by physiotherapist), stressful life events around the onset of pain in 26, serious daily conflicts at present in 30, catastrophizing thinking in 21, repressive thinking in 12, avoidance in 2 and perseverative coping in 6. Many of them did not or partly perceive their somatic tension / discomfort. Multiple factors were considered to inhibit the effect of treatment in those patients. In individual hypnosis, therapeutic conversation, permissive induction and indirect suggestions were employed. Direct suggestions for analgesia were not applied. Among 33 patients, 25 patients experienced hypnotic analgesia during sessions, 14 of whom finished their sessions with the decreased daily pain level or the enhanced effect of medication until the end of the 3rd year. Among them, 5 patients evidently improved (one phantom limb pain and 4 other chronic pain). Hypnosis successfully helped 42% of the patients who had failed to respond to multi disciplinary treatment. The psychosomatic resources in patients need to be more attended and utilized in chronic pain treatment.
