Abstract: Background　To enable community general practitioners（GPs） to screen for thyroid and carotid diseases using the portable ultrasound device high efficiently and effectively at the community level，we developed the Specifications for Community General Practitioners to Screen for Thyroid and Carotid Diseases Using the Portable Ultrasound Device（hereinafter referred to as the Specifications）. Objective　To evaluate the quality of the Specifications using AGREEⅡ precisely，comprehensively and structurally by experts，to make further improvement. Methods　In December 2019，for further improving the specifications via situation adaptation，we invited five experts from community and general hospitals to evaluate the specifications using the modified AGREEⅡ. Results　On the whole，the items of the Specifications were rated high，each was rated higher than four out of seven points，with an average score of higher than five. Compared to the part of thyroid screening，the part of carotid screening was rated lower. And one expert abstained from the assessment for the part of carotid screening. Conclusion　Overall，the experts rated the Specifications high，but specifically，they recommended the use of the part of thyroid screening owing to higher quality，but did not recommend the use of part of carotid screening presently due to lower quality and feasibility. Our study indicates that the AGREEⅡis suitable to be used to evaluate practice guidelines. In terms of evaluating the specific contents of such guidelines to improve the quality，we suggest to use the validity theory to perform a thorough item-by-item expert evaluation.
