Quality changes of clinical practice guidelines for respiratory diseases in China: A systematic review.

BACKGROUND

After the low quality of Chinese clinical practice guidelines (CPGs) for respiratory diseases published from 1979 to 2013 was reported, some handbooks were published to standardize guidelines' development recently. There was a great increase in the production and dissemination of CPGs annually in China, whose quality and potential impact were unknown.

METHODS

A systematic search of four literature databases was performed for the period January 2013 to December 2018 to identify Chinese CPGs for respiratory diseases. Eligible CPGs were evaluated using the appraisal of guidelines for research and evaluation II (AGREE II) instrument.

RESULTS

A total of 197 CPGs were identified for review. Compared with the result of previous study, the increased scores of the six AGREE II domains were screened: Scope and purpose (57.3% vs. 57.8%), Stakeholder involvement (17.6% vs. 25.0%), Rigor of development (10.2% vs. 13.2%), Clarity and presentation (55.2% vs. 58.4%), Applicability (9.3% vs. 25.9%), and Editorial independence (1.1% vs. 6.3%). The improved overall assessment for included CPGs were: Recommended (4, 2.0% vs. 0, 0%) and Recommended with modifications (26, 13.2% vs. 3, 2.8%). The improved level of evidence used to make recommendations were 59, 11.9% versus 168, 22.4% and 88, 17.7% versus 195, 26.0%, A and B, respectively.

CONCLUSIONS

The overall quality of CPGs for respiratory diseases published from 2013 to 2018 in China was slightly improved, but had a big gap with the optimum level, especially in Rigor of development and Editorial independence. Increased efforts are required to enable the development of high-quality evidence-based CPGs for respiratory diseases.
