AB  - PURPOSE: Establishing minimally clinically important difference (MCID) for 
      patient-reported outcomes questionnaires is an important component of outcomes 
      research to understand treatment effectiveness from the patient's perspective. 
      For patients with ulnar neuropathy at the elbow (UNE), these assessments are 
      vital to examine how much change in the questionnaire scores equate to patient 
      satisfaction. METHODS: We calculated the change in scores of Michigan Hand 
      Outcomes Questionnaire (MHQ), Disabilities of the Arm, Shoulder, and Hand (DASH) 
      questionnaire, and Carpal Tunnel Questionnaire (CTQ) from preoperative to 3, 6, 
      and 12 months after ulnar nerve simple decompression procedure. We used the 
      anchor-based approach of receiver operating characteristic curves to determine 
      the MCID. RESULTS: On average, MCID of 10, 12, and 7 points were identified for 
      pain, function, and activities of daily living domains of the MHQ. Similarly, 
      DASH, CTQ-symptom severity scale, and CTQ-function severity scale had an average 
      MCID of 7, 0.7, and 0.3, points respectively. At the 3, 6, and 12 months' time 
      points, an MCID of 9, 8, and 13 points for pain; 12, 12, and 12 points for 
      function; and 6, 8, and 6 points for activities of daily living domains of the 
      MHQ were identified; similarly an MCID of 8, 7, and 7 points for DASH; 0.4, 0.7, 
      and 0.7 points for CTQ-symptom severity scale; and 0.3, 0.3, and 0.4 points for 
      CTQ-function severity scale were established. CONCLUSIONS: The smaller MCIDs of 
      MHQ, DASH, and even smaller MCIDs of CTQ found in our study indicate that a small 
      change in the scores identified satisfied patients. Simple decompression surgery 
      for UNE produced patient satisfaction with only a small change in their 
      questionnaire scores. The implications of this finding are that simple 
      decompression surgery for UNE is a highly effective procedure and that the 
      outcomes questionnaires used are highly responsive, which minimizes sample size 
      requirements for future research studies relating to UNE. TYPE OF STUDY/LEVEL OF 
      EVIDENCE: Therapeutic II.
