Effectiveness of a psychiatric pain clinic.

Medical charts were reviewed for 101 consecutive outpatients seen between January 1, 1993 and July 1, 1996 at a unidisciplinary, psychiatric pain clinic, which exists within a hospital-based, university-run, outpatient service with primary and specialty care clinics. Mean duration of pain was 7 years. Multiple sites of pain were present in 69% of patients. Eighty-eight percent fulfilled DSM-IV criteria for pain disorder. The patients had significantly fewer medical visits and diagnostic tests 6 months after attending the pain clinic, compared with 6 months before (P < 0.0001). Interventions frequently included detoxification and reduction and substitution of medication, and always included psychotherapeutic approaches, particularly support and suggestions.
