Abstract: ObjectiveTo explore bringing floating people into the management for TB control so as to find the effective model for decreasing the TB prevalence and increasing the cure rate,to improve the effectiveness of TB control within the whole city.MethodsRetrospective comparison method was adopted.TB control management between 1993～1997 and 1998～2004 was compared.ResultsThe 5315 percent of new sputum testing positive patients were from floating people.The percentage of patients aged 20 to 30 was the highest,the male was 2.153 times of the female.The occupation of the positive patients included factory workers,commercial service workers and the unemployed.After complementing TBcntrolling for floating people,the number of transfer increased from 9 727 to 6.653,and the accomplishment rate of transfer increased from 63.5 percent to 90.2 percent.From 1993 to 2004,88 798 of floating people were doubted with TB,the percentage was 80.62 percent.Among them 9 496 were with sputum testing positives and 4 845 were negatives(69.5%).The complete supervising rate were 79.1% and 95.6%.The complete management rate were 62.6% and 96.2%.The differences were statistically significant(P<0.05).At the end of 2 months of treatment,the negative rate changed from positive rate increased from 63.3% to 84.6% and at the end of 3 months,from 71.9% to 92.2%.Before floating people were brought project,the cure rate was only 87.2%,however,the cure rate for positive TB patients was reached to 97.2% after being brought into the project.ConclusionAfter establishing the mechanism of supervision and evaluation,bringing floating people into the TB controlling project,strengthening health education and propagandizing,the TB prevalence rate decreased yearly,the cure rate increased constantly,and the effectiveness of TB controlling was improved in Shenzhen city.
