Abstract: Objective To research the effect of new smear positive tuberculosis delayed with convergence case-management in yanbian region.Methods To survey the data of pulmonary tuberculosis patient’s convergence case-management and their cards、medical records from 1993 to 2001 in yanbian, and analysed the effect on delayed diagnosis before and after implementing convergence case-management.Results Convergence transferring diagnosis rate raised from 48.5% to 89.0%, convergence successfully rate raised from 29.0% to 72.4%, while the rate of delayed diagnosis reduced from 29.4% to 10.6%, the average of delayed days reduced from 22.2 d to 7.7 d. On the other hand, the rate of delayed seeking medical advice was 63.4% and 68.8% respectively, and the average of delayed days was 48.9 d and 50.3 d respectively. there is a top-cusp at the 20th week in the date of delay.Conclusion Convergence case-management have significantly effect on delayed diagnosis, while have no effect on the delayed seeking medical advice.It is the key point that reduce delayed diagnosis dependent on improving people in mind to keep heath from tubercle.
