TI  - The Minimal Clinically Important Difference for PROMIS Physical Function in 
      Patients With Thumb Carpometacarpal Arthritis.

AB  - Background: This study was performed to determine the minimal clinically 
      important difference (MCID) of Patient-Reported Outcomes Measurement Information 
      System (PROMIS) Physical Function (PF) computer adaptive test (CAT) for patients 
      with thumb carpometacarpal (CMC) arthritis. Methods: This study retrospectively 
      analyzed data from 152 adults receiving surgical and nonsurgical care for 
      unilateral thumb CMC arthritis at a single institution between January 2016 and 
      January 2018. Patients completed PROMIS PF v1.2/2.0 CAT at each visit. At 
      follow-up, patients also completed two 6-item anchor questions assessing the 
      degree of perceived improvement. Statistical testing analyzed the ability of the 
      clinical anchor to discriminate levels of improvement. An anchor-based MCID 
      estimate was calculated as the mean PROMIS PF change score in the mild 
      improvement group. The anchor-based MCID value was examined for the influence of 
      patient age, initial and final PROMIS scores, and follow-up interval. A 
      distribution-based MCID value was calculated incorporating the standard error of 
      measurement and effect size. Results: The change in PROMIS PF scores was 
      significantly different between encounters where patients reported no change, 
      mild improvement, and much improvement. The anchor-based MCID estimate for PROMIS 
      PF was 3.9 (95% confidence interval, 3.3-4.7). Individual MCID values were weakly 
      correlated with the final absolute PROMIS PF score but did not correlate with 
      patient age, time between visits, or the initial absolute PROMIS PF score. The 
      distribution-based MCID value was 3.5 (95% confidence interval, 3.1-3.9). 
      Conclusions: The estimated range of MCID values for PROMIS PF is 3.5 to 3.9 
      points in patients treated for thumb CMC arthritis.
