AB  - OBJECT: Neurosurgeons are frequently the primary physicians measuring pain relief 
      in patients with trigeminal neuralgia (TN). Unfortunately, the measurement of 
      pain can be complex. The Brief Pain Inventory-Facial (BPI-Facial) is a reliable 
      and validated multidimensional tool that consists of 18 questions. It measures 3 
      domains of pain: 1) pain intensity (worst and average pain intensity), 2) 
      interference with general activities of daily living (ADL), and 3) face-specific 
      pain interference. The objective of this paper is to determine the 
      patient-reported minimum clinically important difference (MCID) using the 
      BPI-Facial. METHODS: The authors conducted a retrospective study of 234 patients 
      with TN seen in a single neurosurgeon's office. Patients completed baseline and 
      1-month follow-up BPI-Facial questionnaires. The MCID was calculated using an 
      anchor-based approach in which the defined anchor was the 7-point patient global 
      impression of change (PGIC). Two statistical methods were employed: mean change 
      score and optimal cutoff point. RESULTS: Using the mean change score method, the 
      investigators calculated the MCID for the 3 domains of the BPIFacial: 44% and 30% 
      improvement in pain intensity at its worst and average, respectively, 54% 
      improvement in interference with general ADL, and 63% improvement in interference 
      with facial ADL. Using the optimal cutoff point method, they also calculated the 
      MCID for the 3 domains of the BPI-Facial: 57% and 28% improvement in pain 
      intensity at its worst and average, respectively, 75% improvement in interference 
      with general ADL, and 62% improvement in interference with facial ADL. 
      CONCLUSIONS: The BPI-Facial is a multidimensional pain scale that measures 3 
      domains of pain. Although 2 statistical methods were used to calculate the MCID, 
      the optimal cutoff point method was the superior one because it used data from 
      the majority of subjects included in this study. A 57% improvement in pain 
      intensity at its worst and a 28% improvement in pain intensity at its average 
      were the MCIDs for patients with facial pain. A greater improvement was needed to 
      achieve the MCID for interference with general and facial ADL. A 75% improvement 
      in interference with general ADL and a 62% improvement in interference with 
      facial ADL were needed to achieve an MCID. While pain intensity is easier to 
      measure, pain's interference with ADL may be more important for patient outcomes 
      when designing or evaluating interventions in the field of TN. The BPI-Facial is 
      a useful instrument to measure changes in multidimensional aspects of pain in 
      patients with TN.
