Abstract:

There were 878 cases of pulmonary tuberculosis (PTB) patients in Chongming District registered in the National Tuberculosis Information Management System from 2011 to 2015, including 337 cases of smear-positive patients and 515 cases of smear-negative patients. The incidence rates of smear-positive and smear-negative cases were 9.57/100 000 (337/3 519 800) and 14.63/100 000 (515/3 519 800) respectively, and there was no statistically significant difference in the incidence of PTB in 5 years (χ 2=4.58, P=0.330). The registered death rate was 1.11/100 000 (39/3 519 800) and the registered mortality rate was 0.44/100 000 (39/878). There were 662 men and 216 women, constituted 75.40% (662/878) and 24.60% (216/878). There was statistically significant difference in the sources of PTB patients (χ 2=38.54, P=0.001). The main sources of PTB were “Symptomatic visit” and “Referral”, which accounted for 77.22% (678/878) and 21.07% (185/878) respectively. Among the 878 patients, the most frequent time of onset was in June, accounting for 10.36% (91/878), while the lowest incidence was observed in February, accounting for 5.92% (52/878). The incidence rates of PTB among floating population and household population in 5 years were 13.57/100000 (105/773 700) and 28.15/100000 (773/2 746 100) respectively, with statistically difference (χ 2=51.44, P<0.01). There was no statistically significant difference in the proportion of TB cases in all age groups (χ 2=26.84, P=0.310), and the higher number of cases was over 65 years and 55-65 years, which accounted for 29.84% (262/878) and 20.27% (178/878). Farmers (27.90%, 245/878) and retired (21.07%, 185/878)were main occupations. Among 337 smear positive cases, 297were cured, and the cure rate was 88.13%. Among 541 smear-negative patients, 496 were successfully treated, and the treatment success rate was 91.68%. In 2011-2015, the TB control in chongming district was slightly effective, and the incidences of male, household and middle aged people were higher, which should be paid more attention to.
