Abstract: Objective To evaluate the tuberculosis (TB) case detection work of Bao’an district of Shenzhen and explore the weakness in order to further improve the case detection mechanism. Method Data from internet based TB reporting system, TB registers was collected from 2007 to 2009. General hospitals were sampled to check the X-ray diagnosis, TB reporting, referral and tracking information, the usage of anti-TB drugs by inpatients. The situation of anti-TB drugs in drug retailers was also investigated and analyzed.  Result From 2007 to 2009, new smear positive case detection rates of Bao’an district were 80.7%, 100.9% and 97.8% respectively. 88.3% of patients were referred by the general hospitals. Among the TB suspects not in place after referral, in these 3 years, 59.3%, 36.7% and 12.1% were due to unknown address respectively. The sample showed that, the TB suspects’ referral rate reached 100% in every public hospital.No inpatient took drugs from hospitals after discharging. In the five sampled retail drug stores, three of them sold anti-TB drugs.  Conclusion The working quality of reporting and referral of TB suspects in general hospitals of Bao’an District has improved. The case detection rate is in a relatively high level. However, the loss of patients of floating population and lack of monitoring of anti-TB drug retailers is the weakness part in the process of TB case detection.
