Abstract
BACKGROUND: As a practice-oriented discipline, strict adherence to reporting guidelines is particularly important in randomized controlled trial (RCT) abstracts of the nursing area. However, whether abstract reports after 2010 have complied with the Consolidated Standards of Reporting Trials for Abstracts (CONSORT-A) guideline is unclear. This study aimed to evaluate whether the publication of CONSORT-A has improved abstract reporting in nursing and explores the factors associated with better adherence to the guidelines. METHODS: We searched the Web of Science for 200 RCTs randomly selected from ten nursing journals. We used a data extraction form based on CONSORT-A, including 16 items, to analyze the reporting adherence to the guidelines, and the reporting rate of each item and the total score for each abstract were used to indicate adherence and overall quality score (OQS, range 0-16). A comparison of the total mean score between the two periods was made, and affecting factors were analyzed. RESULTS: In the studies we included, 48 abstracts were published pre-CONSORT-A whereas 152 post-CONSORT-A. The overall mean score for reporting adherence to 16 items was 7.41 ± 2.78 and 9.16 ± 2.76 for pre- and post-CONSORT-A, respectively (total score: 16). The most poorly reported items are "harms (0%)," "outcomes in method (8.5%)," "randomization (25%)," and "blinding (6.5%)." Items including the year of publication, impact factor, multiple center trial, word count, and structured abstract are significantly associated with higher adherence. CONCLUSIONS: The adherence to abstract reporting in nursing literature has improved since the CONSORT-A era, but the overall completeness of RCT abstracts remained low. A joint effort by authors, editors, and journals is necessary to improve reporting quality of RCT abstracts.
