Background:
The aim of this study was to assess adherence to the Consolidated Standards of Reporting Trials (CONSORT) extension for Abstracts (CONSORT-A) in the highest-impact anesthesiology journals.
Methods:
This was a descriptive, cross-sectional, methodological study. We analyzed whether abstracts of randomized controlled trials (RCTs) published in the highest-impact anesthesiology journals between 2014 and 2016 adhered with CONSORT-A. RCT abstracts published in the seven first-quartile journals in the Journal Citation Reports (JCR) category Anesthesiology were analyzed. The primary outcome was adherence to the 17-item CONSORT-A checklist. Secondary outcomes were adherence to individual checklist items and adherence with the checklist across the individual journals.
Results:
Search results yielded 688 records, of which 622 abstracts were analyzed. Analysis of the total score of the CONSORT-A checklist indicated a per-article median of 41% (interquartile range 35-53%). The European Journal of Anesthesiology had the highest overall adherence rate (53%), whereas Anaesthesia had the lowest (32%). The lowest adherence was observed for the following items: Trial design (18%), Contact of the authors as an e-mail address of the corresponding author (16%), Recruitment status (9%), Number of participants analyzed (8%), Randomization (3%), and Funding (0.2%).
Conclusions:
RCT abstracts published in top anesthesiology journals are poorly reported, providing insufficient information to readers. Interventions are needed to increase adherence to relevant reporting checklists for writing RCT abstracts.
