title: Predictors of clinical outcome in fibromyalgia after a brief interdisciplinary fibromyalgia treatment program: single center experience.
abstract: OBJECTIVE
  To determine which patient characteristics are closely associated with a positive response to a brief interdisciplinary fibromyalgia treatment program (FTP).
  
  
  METHODS
  A prospective cohort study.
  
  
  METHODS
  FTP at a tertiary medical center.
  
  
  METHODS
  A total of 536 patients with a confirmed diagnosis of fibromyalgia who underwent the FTP and completed the Fibromyalgia Impact Questionnaire (FIQ) at baseline and 6-12 months after treatment.
  
  
  METHODS
  A brief 1.5-day interdisciplinary FTP, which included evaluation with a registered nurse and a physician for a diagnosis or confirmation of fibromyalgia, fibromyalgia education, interactive self management session, and physical and occupational therapy.
  
  
  METHODS
  The responder definition was an improvement of 14% or more in the FIQ total score from their baseline to 6-12 months after treatment.
  
  
  RESULTS
  Mean (standard deviation) age of our patients was 50.3 ± 13.0 years; 515 women (96%) and 23 men (4%). Two hundred forty-eight patients (46%) met the responder definition at 6-12 months follow-up. In an univariate analysis, younger age (P = .008), college or higher education (P = .02), fewer tender points (P = .048), and higher FIQ depression subscore (P = .02) significantly predicted positive response. In a multivariate analysis, these factors all remained statistically significant. In addition, a positive abuse history became significant (P = .03). There was no significant association for gender, duration of symptoms, marital status, employment, smoking status, or 3 numeric rating scale pain scores.
  
  
  CONCLUSIONS
  Patients with younger age, more years of education (with college or graduate degree), higher baseline FIQ depression score, lower tender point count, and absent abuse history experience greater benefit from a brief FTP.
