OBJECTIVE: To describe the extent to which adherence to Consolidated Standards of
Reporting Trials (CONSORT) statement in randomized controlled trials (RCTs) in
adult traumatic brain injury (TBI) has improved over time. DATA SOURCES: MEDLINE,
PsycINFO, and CINAHL databases were searched from inception to September 2013.
STUDY SELECTION: Primary report of RCTs in adult TBI. The quality of reporting on
CONSORT checklist items was examined and compared over time. Study selection was
conducted by 2 researchers independently. Any disagreements were solved by
discussion. DATA EXTRACTION: Two reviewers independently conducted data
extraction based on a set of structured data extraction forms. Data regarding the
publication years, size, locations, participation centers, intervention types,
intervention groups, and CONSORT checklist items were extracted from the
including trials. DATA SYNTHESIS: Of 105 trials reviewed, 38.1%, 5.7%, and 32.4%
investigated drugs, surgical procedures, and rehabilitations as the intervention
of interest, respectively. Among reports published between the 2 periods 2002 and
2010 (n=51) and 2011 and September 2013 (n=16), the median sample sizes were 99
and 118; 39.2% and 37.5% of all reports detailed implementation of the
randomization process; 60.8% and 43.8% provided information on the method of
allocation concealment; 56.9% and 31.3% stated how blinding was achieved; 15.7%
and 43.8% reported information regarding trial registration; and only 2.0% and
6.3% stated where the full trial protocol could be accessed, all respectively.
CONCLUSIONS: Reporting of several important methodological aspects of RCTs
conducted in adult TBI populations improved over the years; however, the quality
of reporting remains below an acceptable level. The small sample sizes suggest
that many RCTs are likely underpowered. Further improvement is recommended in
designing and reporting RCTs.
