Background:
This study was designed to examine the current use of patient-reported outcome measures (PROMs) and minimal clinically important difference (MCID) calculations in the hand surgery literature in an effort to standardize their use for research purposes.
Methods:
A systematic review of the hand surgery literature was conducted. All nonshoulder upper extremity articles utilizing PROMs were compared between different journals, different surgical indications, and differing usage. MCID values were reported, and calculation methods assessed.
Results:
In total, 4677 articles were reviewed, and 410 met the inclusion criteria of containing at least one PROM. Of the 410 articles reporting PROMs, 148 also mentioned an associated MCID. Of the articles that mentioned MCIDs, 14 calculated MCID values based on their specific clinical populations, whereas the remainder referenced prior studies. An estimated 35 different PROMs were reported in the study period; 95 different MCID values were referenced from 65 unique articles.
Conclusions:
There are many different PROMs currently being used in hand surgery clinical reports. The reported MCIDs from their related PROMs are from multiple different sources and calculated by different methods. The lack of standardization in the hand surgery literature makes interpretation of studies utilizing PROMs difficult. There is a need for a standardized method of calculating MCID values and applying these values to established PROMs for nonshoulder upper extremity conditions.
