Abstract: Objective To improve and increase the rate of case-finding.Methods 6 counties were chosen at random according to the rate of new smear positive pulmonary tuberculosis cases from 3 different level,and adopted some vigorous measures in the counties.We tried our best to educate people to have the knowlege of TB symptoms and made them know the necessity for patients to see TB doctor in time.Then we investigated and compare health people,pulmonary TB patients and inpatients in general hospitals before and after the adopted measeures.Result Through wide propaganda and health education,people get to know much about tuberculosis.More and more people who have tuberculosis symptoms are willing to go to tuberculosis dispensary.The rate of patients going to see TB doctors directly went up from 2.9%to 27.0% before and after interventien.For issued documents on tuberculosis classified management,the pulmonary tuberculosis inpatients in general hospital dropped from 0.30%to 0.14%.During the same period,the rate of failing to report came down from 28.2%to 15.9%.After adopting the measures,the rate of new smear positive pulmonary tuberculosis was 13.45/100 000 in 1995,which raised obviouslly,comparing with 11.94/100 000in 1994 before intervention ( P<0.01) .The new registered smear positive cases increased 30.3%,2 050 comparing with 2 940,before interventien of 4 years(1990~1993)and after interventien of 4 years(1994~1997).Cnclusion It's very important to strengthen propaganda and education.And stressing on pulmonary tuberculosis patients' classified management is necessary and efficient.The general hospital should set up fluoroscopy register.These measures can raise case notification rate of new smear positive pulmonary tuberculosis case effectively.
