Abstract: Objective To understand the status of referral and arrival and diagnosis of pulmonary tuberculosis (PTB) patients or suspicious TB patients reported by internet-based reporting system by non-TB control institutions of Chifeng city from 2009 to 2012 in order to improve case detection.  Methods The referral, tracing and checking report forms of 10 812 PTB patients reported by non-TB control institutions in tuberculosis management information system of Chifeng from 2009 to 2012 was used. The referral arrival rate, tracing arrival rate, total arrival rate, detection rate and the contribution rate on TB case detection by non-TB institutions of 7981 cases referred was analyzed.  Results For the patients reported through internet-based reporting system by non-TB control institutions of Chifeng from 2009 to 2012, the referral arrival rate was 34.1%（648/1900）, 30.4%（613/2017）, 32.0%（632/1976） and 33.4%（698/2088） respectively. The tracing arrival rate was 85.5%（1071/1252）, 95.8%（1345/1404）, 95.8%（1288/1344） and 94.2%（1310/1390）. The total arrival rate was 91.3%（1734/1900）, 97.4%（1965/2017）, 97.4%（1924/1976） and 96.6%（2017/2088） respectively. Among arrival patients, the detection rate of active PTB was 59.7%（4563/7640） and that of smear positive PTB was 24.0%（1833/7640）. The contribution rate on active PTB case detection by non-TB institutions was 29.0%（4563/15 736） and on smear positive PTB was 27.7%（1833/6625）.  Conclusion The referral arrival rate had large room for improvement in Chifeng city, the tracing arrival rate and the total arrival rate maintained at a high level.
