[Application of derivative Dolphe method in the constitution of practice guidelines on prevention and treatment of hypertension for primary care physicians].
OBJECTIVE
To evaluate the necessity, scientificity, and feasibility of the drafted Practice Guidelines on Prevention and Treatment of Hypertension for Primary Care Physicians.


METHODS
Derivative Dolphe Method was used to collect the responses from 50 experts in hypertension or related fields within the nation. An evaluation score of 1 to 5 was given to each item for selection, 1 for highly disagreed and 5 for highly agreed. The mean, standard deviation (SD) and coefficient of variance (CV) of the scores were calculated.


RESULTS
(1) 90% experts responded to the evaluation sheet. (2) The mean score were above 4 for the five out of the six items related to necessity, the SD varied from 0.51 to 1.05, and the CV from 0.11 to 0.30. (3) Among the 28 items related to scientificity and rationality, the mean score was above 4 for 25 items and was between 3.5 and 4 for other three items. The CV was generally lower than 0.35. (4) Among the seven items related to feasibility, the mean score for five of them was lower than 4, and the CV varied from 0.21 to 0.33.


CONCLUSIONS
The results indicate that the necessity and scientificity of the most content of the guidelines are confirmed by the invited experts.
