Analysis of detection and treatment outcomes of pulmonary tuberculosis in China from 2001 to 2010

Objective To analyze case finding and treatment outcomes of pulmonary tuberculosis in China from 2001 to 2010 and provide scientific evidence for TB control and prevention.Methods The data of TB information management system of National Center for Tuberculosis Control and Prevention,Chinese Center for Disease Control and Prevention,TB Control Quarterly Report from 2004 to 2010 and TB Control Annual Report from 2001 to 2010 in China were used,combined with special investigation to collect TB data.Description statistic was applied to analyse the referral and tracing situation of 5 799 344 TB patients reported by general hospitals via internet-based infectious disease reporting system from 2004 to 2010,as well as the situation of 15 864 493 TB suspects for the first visit in TB dispensary from 2006 to 2010 and 8 285 978 active TB patients registered in TB dispensary at all levels from 2001 to 2010.Results The average referral arrival rate and tracing arrival rate were 45.1%(2 614 216/5 799 344) and 64.6%(1 740 840/2 695 781) respectively by general hospitals via internet-based infectious disease reporting system during 2004 to 2010.The overall arrival rate has increased from 56.9%(263 324/463 085) in 2004 to 86.5%(846 268/978 477) in 2010.From 2006 to 2010,about 15 864 493 TB suspects were treated by TB dispensary at all levels,almost 3.173 million per year.From 2001 to 2010,8 285 978 active TB patients were found by TB dispensary at all levels,among whom 4 501 587(54.3%) were smear positive,3 563 369(43.0%) were smear negative and 221 022(2.7%) were no smear examination.The proportion of re-treatment dropped from 15.8%(89 112/562 801) in 2005 to 11.2%(54 216/484 115) in 2010 and the proportion of no smear examination dropped from 7.9%(39 396/495 635) in 2001 to 0.3%(2461/906 856) in 2010.Conclusion With the implementing of National Tuberculosis Control Programme,the TB case detection has been continuously improved and remarkable achievement has been made in China.
