Abstract: Objective

To analyze the trend of the registration of active pulmonary tuberculosis (PTB) patients and new smear positive PTB patients in China (Excluding Hong Kong, Macao and Taiwan) from 2011 to 2015, and to provide reference for the evaluation of case detection and registration during the Twelfth Five-year TB Control Programme.

Methods

The numbers of active PTB and new smear positive PTB patients from 2011 to 2015 from the National Tuberculosis Information Management System were 4268687 and 1415537 respectively. The annual registration rates of active PTB and smear positive PTB patients, as well as the proportion of new smear positive PTB in active PTB were calculated and compared both nationwide and by provinces.

Results

In 2011 and 2015, the proportions of new smear positive PTB in active PTB were 41.6% (377005/905344) and 26.4% (210581/798927) respectively. The registration rates of active PTB and new smear positive PTB in 2011 were 67.5/100000 (905344/1340910000) and 28.1/100000 (377005/1340910000) respectively, while those in 2015 were 58.4/100000 (798927/1367820000) and 15.4/100000 (210581/1367820000) respectively. The registration rate of active PTB decreased by 1.2% from 2011 to 2012, 5.0% from 2012 to 2013, 3.4% from 2013 to 2014 and 2.6% from 2014 to 2015, so did that of new smear positive PTB (by 16.1% from 2011 to 2012, 12.8% from 2012 to 2013, 14.6% from 2013 to 2014 and 10.7% from 2014 to 2015). The proportion of new smear positive PTB in active PTB of 31 provinces ranged from 24.1% to 66.3% in 2011, from 20.7% to 63.1% in 2012, from 17.8% to 60.6% in 2013, from 13.8% to 49.6% in 2014 and from 12.3% to 48.1% in 2015.

Conclusion

There is a steady decline in the registration rate of active PTB but a significant decline in that of new smear positive PTB during the Twelfth Five-year TB Control Programme. Various measures need to be implemented to improve PTB case detection and registration.
