Abstract: Objective To analyze the implementation effect of new tuberculosis (TB) control model of designated hospital in Jiangsu province, and to provide scientific evidence for TB control and prevention strategy development. Methods Ten counties which conducted TB control by designated hospitals (Designated Hospital Model) and 10 counties which conducted TB control by county centers for disease control and prevention (CDC) (CDC Model) were selected. Data of diagnosis delay, referral and tracing, systematic management, treatment outcome and data quality of 10 578 TB cases registered from January 2012 to December 2012 were collected. SPSS 17.0 was used for data analysis to evaluate the effects of two models. Results The registration rates were 55.60/100 000 (4768/8 575 823) and 55.93/100 000 (5810/10 388 634) respectively (χ²=0.091, P=0.763), the overall arrival rates were 99.1% (4939/4985) and 99.2%(6064/6111) respectively (χ²=0.780, P=0.3771), durations from diagnosis to registration were (0.021±0.009) day and (0.025±0.010) day respectively (t=0.419, P>0.05), systematic management rates were 99.0% (5048/5097) and 98.7% (5645/5719) respectively (χ²=2.65, P=0.103), and treatment completion rates of smear negative TB cases were 96.6% (3182/3295) and 97.4% (3661/3760) respectively (χ²=3.82, P>0.05) for Designated Hospital Model and CDC Model, which were no statistical significance. The average duration from getting sick to TB diagnosis was (11.117±6.109) day for Designated Hospital Model, less than (15.399±6.866) day for CDC Model (t=12.42, P<0.001). The consulting rates with symptoms and signs were 52.0% (2479/4768) and 33.8% (1966/5810) respectively (χ²=352.468, P<0.0001), referral rates were 99.1% (4941/4985) and 98.5% (6017/6111) respectively (χ²=9.606, P=0.0019), tracing arrival rates were 99.6% (1320/1325) and 97.9% (1559/1593) respectively (χ²=16.993, P=0.000 04) for Designated Hospital Model and CDC Model, which were all higher in Designated Hospital Model than CDC Model. The cure rates of new smear positive cases were 89.8% (1172/1305) and 94.7% (1293/1366) respectively (χ²=22.03, P<0.0001), cure rates of retreated smear positive cases were 80.8% (274/339) and 88.9% (335/377) respectively (χ²=9.06, P<0.01), timely rates of information entry were 98.9% (23 571/23 840) and 99.0% (28 773/29 050) respectively (χ²=4.088, P=0.043), and completion rates of information entry were 98.8% (28 272/28 608) and 99.4% (34 646/34 860) respectively (χ²=60.113, P<0.0001) for Designated Hospital Model and CDC Model, which were all lower in Designated Hospital Model than CDC Model, while the rates still meet the requirements of national TB control. Conclusion The implementation of Designated Hospital Model at county level in Jiangsu province has achieved great effect. Designated Hospital Model of TB control is the inexorable trend which accords with the demands of the medical institutions reform, and can adapt to the needs of TB control and be implemented according to the local conditions.
