Objective: The extent of intervention reporting in emergency medicine journals remains unclear. The primary objective is to assess overall completion of the Template for Intervention Description and Replication (TIDieR) checklist described in emergency medicine randomized clinical trials (RCTs). The secondary outcomes were to (1) compare reporting before and after TIDieR publication; (2) evaluate factors associated with intervention reporting. Methods: Our cross-sectional study used Google Scholar's metrics to identify seven emergency medicine journals; of which, we randomly sampled 300 articles. Using two PubMed searches, we extracted 150 RCTs before and after publications of TIDieR. Two investigators independently extracted data. The primary analysis to measure overall completion included descriptive statistics for each checklist item. Our secondary analysis used an interrupted time series analysis and generalized estimating equations to determine the effect of TIDieR publication on intervention reporting. Results: Our initial search yielded 635 articles; from which, we randomly sampled 300 articles. We excluded 67 articles, leaving 233 for analysis. The mean number of TIDieR items reported was 5.4 (standard deviation = 1.18). Of the 233 trials, 42.9% provided information about materials, 67% provided intervention procedures, and 99.1% provided intervention delivery. The least reported items were intervention modifications (2.6%), intervention adherence assessment methods (3.4%), and intervention adherence assessment outcomes (2.2%). Conclusions: The completeness of intervention reporting is suboptimal in emergency medicine journals, necessitating improvement. The current state of adherence could be improved through the combined efforts of journal editors, major editorial organizations, and authors.
