Abstract: Objective To study the ways and feasibilities of further increasing the rate of arrival by referring of TB patients and suspects,so as to increase the discovery rate of patients with pulmonary TB. Methods Carrying out the some scale stratified sampling method,selecting 20 counties as project areas,in which the number of population is over 300 thousands in Heilongjiang province.Based on the available referral system,carry out a series of intervention.In the same time,select other 20 counties as control group.Study the number of TB patients and suspects who are referred and arrived. Results During the project,the arrival rate is 82.5% in the 20 project counties,and the arrival rate is 58.8% in control counties,there were significant difference between two groups(χ²=1 016.510 4,P<0.01).The number of the TB cases,the smear-positive cases and the new smear-positive cases were increased by 10.6%、11.1% and 12.7% compared with that in the same period of previous year in project counties.While in the control group,the number of the TB cases was increased by 11.2%,the number of the smear-positive and the new smear-positive patients were decreased by 1.9% and 1.3% compared with that in the same period of the previous year. Conclusion The intervention to strengthen the referral and tracing system could increase the discovery rate of patients in the area with poor baseline.
