Quality of observational studies in prestigious journals of occupational medicine and health based on Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: a cross-sectional study.

ABSTRACT: The present study applied the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement to observational studies published in prestigious occupational medicine and health journals.A total of 60 articles was evaluated. All sub-items were reported in 63.74% (95% confidence interval [CI], 56.24-71.24%), not reported in 29.70% (95% CI, 20.2-39.2%), and not applicable in 6.56% (95% CI, 4.86-8.26%) of the studies. Of the 45 sub-items investigated in this survey, eight were reported 100% of the time, 13 were addressed in more than 90% of the articles, 22 were included in more than 75% of the studies, and 27 sub-items were applied in more than 50% of the articles published in the journals included in this study.

Project description:Observational studies are the most frequently published studies in literature. When randomized controlled trials cannot be conducted because of ethical or practical considerations, an observational study design is the first choice. The STROBE Statement (STrengthening the Reporting of OBservational studies in Epidemiology) was developed to provide guidance on how to adequately report observational studies.The objectives were 1) to evaluate the quality of reporting of observational studies of otorhinolaryngologic literature using the STROBE Statement checklist, 2) to compare the quality of reporting of observational studies in the top 5 Ear, Nose, Throat (ENT) journals versus the top 5 general medical journals and 3) to formulate recommendations to improve adequate reporting of observational research in otorhinolaryngologic literature.The top 5 general medical journals and top 5 otorhinolaryngologic journals were selected based on their ISI Web of Knowledge impact factors. On August 3rd, 2015, we performed a PubMed search using different filters to retrieve observational articles from these journals. Studies were selected from 2010 to 2014 for the general medical journals and from 2015 for the ENT journals. We assessed all STROBE items to examine how many items were reported adequately for each journal type.The articles in the top 5 general medical journals (n = 11) reported a mean of 69.2% (95% confidence interval (CI): 65.8%-72.7%; median 70.6%), whereas the top 5 ENT journals (n = 29) reported a mean of 51.4% (95% CI: 47.7%-55.0%; median 50.0%). The two journal types reported STROBE items significantly different (p < .001).Quality of reporting of observational studies in otorhinolaryngologic articles can considerably enhance. The quality of reporting was better in general medical journals compared to ENT journals. To improve the quality of reporting of observational studies, we recommend authors and editors to endorse and actively implement the STROBE Statement.

Project description:BackgroundIn uncontrolled before-after studies, CONSORT was shown to improve the reporting of randomised trials. Before-after studies ignore underlying secular trends and may overestimate the impact of interventions. Our aim was to assess the impact of the 2007 STROBE statement publication on the quality of observational study reporting, using both uncontrolled before-after analyses and interrupted time series.MethodsFor this quasi-experimental study, original articles reporting cohort, case-control, and cross-sectional studies published between 2004 and 2010 in the four dermatological journals having the highest 5-year impact factors (? 4) were selected. We compared the proportions of STROBE items (STROBE score) adequately reported in each article during three periods, two pre STROBE period (2004-2005 and 2006-2007) and one post STROBE period (2008-2010). Segmented regression analysis of interrupted time series was also performed.ResultsOf the 456 included articles, 187 (41%) reported cohort studies, 166 (36.4%) cross-sectional studies, and 103 (22.6%) case-control studies. The median STROBE score was 57% (range, 18%-98%). Before-after analysis evidenced significant STROBE score increases between the two pre-STROBE periods and between the earliest pre-STROBE period and the post-STROBE period (median score2004-05 48% versus median score2008-10 58%, p<0.001) but not between the immediate pre-STROBE period and the post-STROBE period (median score2006-07 58% versus median score2008-10 58%, p?=?0.42). In the pre STROBE period, the six-monthly mean STROBE score increased significantly, by 1.19% per six-month period (absolute increase 95%CI, 0.26% to 2.11%, p?=?0.016). By segmented analysis, no significant changes in STROBE score trends occurred (-0.40%; 95%CI, -2.20 to 1.41; p?=?0.64) in the post STROBE statement publication.InterpretationThe quality of reports increased over time but was not affected by STROBE. Our findings raise concerns about the relevance of uncontrolled before-after analysis for estimating the impact of guidelines.
