Scientific articleThe Minimal Clinically Important Difference of the Michigan Hand Outcomes Questionnaire
Section snippets
Methods
Three prospective cohort studies with ongoing data collection were used to measure the MCID for the MHQ. The conditions of interest are RA of the hand treated with silicone metacarpophalangeal joint arthroplasty (SMPA), CTS treated with limited-incision technique carpal tunnel release, and treatment of DRF using the volar locking plating system (VLPS).4, 7, 8 Data obtained from these prospective cohorts studies have not previously been used to measure the MCID for these respective conditions.
Results
Forty RA patients, 53 CTS patients, and 51 DRF patients completed the MHQ at 2 time points. A summary of patient demographic data is shown Table 1.
Discussion
This article illustrates the process of identifying the MCID of a patient-rated outcomes questionnaire. Our study indicates that a different strategy is necessary when calculating the MCID for various patient populations. For instance, DRF fixation with VLPS allows patients to re-engage in everyday activities much sooner than previous methods of DRF fixation.8 Because of this, patient-reported satisfaction was relatively high only 3 months after fixation. In fact, scores on all domains were

2023, Journal of Hand Surgery Global OnlineCitation Excerpt :One systematic review found that of 1,709 upper extremity–focused articles using PROMs published from 2014 to 2016, only 7.5% of them referenced an MCID.20 Studies have investigated MCID values for PROMs commonly used in CTS, with proposed MCID values of 0.46 and 0.28 points for the BCTQ symptom severity and functional status subscales, respectively; 23, 13, and 8 points for the MHQ pain, function, and work subscales, respectively; 10.83 points for the DASH; 15.91 points for the QuickDASH; and 24 points for the Patient-Rated Wrist Evaluation.21–24 However, the variation in MCID calculation methods and extensive variation in use of PROM instruments impacts the interpretation of these values and their utility in routine clinical practice at present.20
