Using the RIGHT statement to evaluate the reporting quality of clinical practice guidelines in traditional Chinese medicine

OBJECTIVE: To evaluate the reporting quality of clinical practice guidelines (CPGs) in traditional Chinese medicine (TCM). METHODS: A systematic search was undertaken to extract CPGs for TCM. The RIGHT (Reporting Items for practice Guidelines in Healthcare) statement was used to calculate scores for the reporting quality in terms of domains and items, followed by a subgroup analysis of the results and determination of the correlation between the RIGHT and AGREE II (Appraisal of Guidelines for Research and Evaluation II) scores. RESULTS: Overall, 539 TCM CPGs were included. (1) The mean scores (Med, IQR) for each RIGHT domain were as follows: basic information (4, 1), background (3, 2), evidence (0, 0), recommendations (2, 2), review and quality assurance (0, 0), funding and declaration and management of interests (0, 0.5), and other information (0, 0). (2) The items with a low reporting rate (<10%) included 2, 5, 8b, 9a, 10a, 10b, 11a, 11b, 14a, 14b, 14c, 16, 17, 19b, 20, 21, and 22, and those with a high reporting rate (> 90%) included 1a, 1b, 1c, 7b, 13a, and 13b. (3) In recent years, the reporting quality of TCM CPGs has improved, and there was a significant difference among the organizations (P = 0.000), where that of the updated versions was greater than that of the historical versions (P = 0.047). (4) The RIGHT and AGREE II scores were positively correlated (P = 0.014). CONCLUSIONS: At present, although the reporting quality of TCM CPGs is improving, the overall quality remains suboptimal. Guideline developers should strictly follow the evidence-based process of developing guidelines and should follow the RIGHT statement to produce a standardized report when writing guidelines.
