[The study on Delphi filtering the indicators of evaluation on the diagnosis, treatment and management of MDR-TB].
OBJECTIVE
To filter the indicators of evaluation on the diagnosis, treatment and management of MDR-TB through Delphi.


METHODS
Three rounds Delphi was implemented by asking for the 30 experts'score and suggestion of 60 evaluation indicators. The experts were selected from experienced MDR-TB workers. Then the concentration degree (with each indicator's score average and full mark rate to reflect) and coordination degree (with coordination coefficient w to reflect) were analyzed, and the coefficient of variation of each indicator, enthusiasm and authority coefficient Cr etc were calculated. After that, new indicators system was constructed and the experts' were asked for suggestion again. The enthusiasm and coordinate coefficient were used to measure the effect of Delphi.


RESULTS
All of the enthusiasm coefficients of experts in three rounds were 100% (30/30), and 40% (12/30), 53% (16/30) and 10% (3/30) of the experts gave suggestions. The degrees of experts' authority in the first 2 rounds were high and the averages were 0.82 and 0.86, respectively. A total of 34 indicators were left after 6 indicators modified and 26 indicators deleted. The 10 indicators were the core indicators, and the average scores of 34 indicators were all higher than 4.7 and the coefficients of variation were less than 0.1, respectively. The coordination coefficients of specialists' opinion were 0.36, 0.25 and 0.68, respectively.


CONCLUSIONS
The final evaluation indicator system include 34 indicators, and the result of the filtering indicators on the diagnosis, treatment and management of MDR-TB through Delphi is good.
