| Summary: | <h4>Objective</h4>To evaluate the quality of clinical practice guidelines (CPGs) for otorhinolaryngology in China.<h4>Materials and methods</h4>A systematic search of relevant literature databases (CBM, WANFANG, VIP, CNKI, China Guideline Clearinghouse) published between 1978 and March 2012 was undertaken to identify and select CPGs related to otorhinolaryngology. Four independent reviewers assessed the eligible guidelines using the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. Their degree of agreement was evaluated using the intraclass correlation coefficient (ICC).<h4>Result</h4>From 170 citations, 21 relevant guidelines were included. The overall agreement among reviewers was moderate (ICC = 0.87; 95% confidence interval [CI], 0.78-0.91). The scores for each of the AGREE domains were the following: "scope and purpose" (mean ± standard error [SE] = 45.4±4.4; ICC = 0.92), "stakeholder involvement" (mean ± SE = 30.4±3.1; ICC = 0.81), "rigor of development" (mean ± SE = 20.9±2.8; ICC = 0.87), "clarity of presentation" (mean ± SE = 48.8±3.7; ICC = 0.80), "applicability" (mean ± SE = 12.6±1.7; ICC = 0.72), and "editorial independence" (mean ± SE = 6.2±0.8; ICC = 0.76). Three guidelines (14%) mentioned updates, and the average update frequency was 7 years. None used the GRADE system.<h4>Conclusion</h4>The quality of otorhinolaryngology guidelines in China is low. Greater efforts are needed to provide high-quality guidelines that serve as a useful and reliable tool for clinical decision-making in this field.
