A Systematic Review of Outcome Measures Use Analytical Approaches Reporting Methods and Publication Volume by Year in Low Back Pain Trials Published between 1980 and 2012: Respice adspice et prospice

摘要

BackgroundIncreasing patient-reported outcome measures in the 1980s and 1990s led to the development of recommendations at the turn of the millennium for standardising outcome measures in non-specific low back pain (LBP) trials. Whether these recommendations impacted use is unclear. Previous work has examined citation counts, but actual use and change over time, has not been explored. Since 2011, there has been some consensus on the optimal methods for reporting back pain trial outcomes. We explored reporting practice, outcome measure use, and publications over time.
