Evaluation Of The Reporting Quality Of Guidelines For Gastric Cancer Using The Right Checklist

Background: Gastric cancer is the fifth most common type of cancer globally. We aimed to evaluate the reporting quality of clinical practice guidelines in the field of gastric cancer. Methods: We searched Medline (via PubMed), China Biology Medicine, Chinese National Knowledge Infrastructure and WanFang databases and the websites of the main guideline development organizations from 2018 to 2020 for guidelines on gastric cancer. Data were extracted and the reporting quality evaluated by two researchers independently using the Reporting Items for Practice Guidelines in Healthcare (RIGHT) checklist. We assessed the compliance of the guidelines to each of the 35 items of RIGHT and summarized the reporting proportions of the seven domains of RIGHT. Results: Eighteen guidelines were included. The mean proportion of appropriately reported RIGHT items was 52.4%. Among the seven domains of the RIGHT checklist, Basic information had the highest reporting rate (78.7%), and Review and quality assurance domain the lowest rate (16.7%). The domains Evidence (40.0%), Funding and declaration and management of interests (43.1%), and Other information (31.5%) had also reporting rates below 50%. Two RIGHT items (17 and 19b) were not reported by any of the guidelines. Conclusions: The reporting quality of gastric cancer guidelines published in the years 2018-2020 was suboptimal, especially regarding the reporting of review, quality assurance and evidence. Guideline developers should pay attention on rigorous reporting following international standard to improve the quality of guidelines.
