Background: When evaluating randomized controlled trials(RCTs), nurses usually refer to the abstracts to make an initial assessment of the results and to determine whether a full-text review is required. Aims: To determine whether the publication of Consolidated Standards of Reporting Trials (CONSORT) for abstracts resulted in an improvement in the abstracts report of nursing RCTs. Methods: This research was a cross-sectional study. Web of Science was searched. 200 RCTs were randomly selected from ten high-impact nursing journals. CONSORT-A checklist was used to assess abstracts. Total score on checklists, comparison on total scores between two periods, and effect factors were analyzed. Results: Mean overall adherence across all abstracts was 8.85±2.18 which significantly improved with the time span. The most poorly reported items were ‘harms’, ‘outcomes in method’, and ‘method of blinding’ which appeared in 0, 8.5% and 16.5% of abstracts, respectively. Recent year of publication(P=0.014), Journal impact factor (P=0.000), multiple center trial (P=0.000), and structured abstract (P=0.008) were associated significantly with a high reporting quality. Conclusions: Although not defined all of abstracts in nursing area, our sample reflect the general trend that there was limited adherence to the CONSORT-A among abstracts in nursing literature. It is necessary to promote and actively apply the CONSORT-A guideline.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
