Study Of Influential Factors Of TB Control Effect And Patient Discovereding Rate In Shanxi Province From 1994 To 2005

Object To analysis the current situation of TB control in Shanxi province from 1994 to 2005; estimate the effect of modern TB controlling strategy; reveal the epidemiology characteristic and the correlating factors in patient discovering rate and cure rate for tuberculosis and to provide scientific evidences for developing measures for tuberculosis control.Method Collect and analyze the monthly, quarterly and annual report forms from 1994 to 2005; Collect the stage appraisal questionnaire of TB control program of the whole country, the middle appraisal questionnaire of TB control program for the global found and the annual work summary. Analyze the situation of patient discovery, turnover, number of targeting found and health education, professional training and supervising management. The results were analyzed with Excel and SPSS13.0.Result The fraction rate of coverage was 100% from the practicing of DOTS in 1994; the registry number of infectious TB patients increased year by year. In 1994, the new registry rate of infectious TB patients was 9.68/100 thousand and the discovery rate of new infectious TB patient was 19.35%. In 2005, the former was 38.88/100 thousand and the latter was 81.86%, four times than 1994. The sputum negative conversion rate of infectious patients at the end of 2 months of initial treatment was 92.62%, 84.45% in the retreatment and 88.31% for the average. The fraction rate of coverage, the discovery rate of new infectious patients and cure rate reached the aim introduced by WHO and Ministry of Public Health (100%,70% and 85% for each).There was a positive correlation between the number of TB targeting funds and the discovery rate of infectious patients r=0.856(r2=0.732,P<0.001), and the regression equation was y=101.349x+10.906 . And there was also a positive correlation between health education and the discovery rate of infectious patients r=0.978(r2=0.957,P=0.022,y=318.239x-13.674.The training times of medical staff had influence on discovery rate of patients r=0.891. And the whole range supervise resulted in a cure rate of 85%,r=0.867.Conclusion A satisfactory result of DOTS in TB control program was found in Shanxi province. The fraction rate of DOTS was 100%,the discovery rate of new infectious patients was 81.86% and the cure rate was 88.3%. The number of targeting funds had decisive action on the discovery rate of new infectious patients. Health education played an important role in elevation of the discovery rate of new infectious patients. Increase of training times for medical staff also had effect on it. And whole range supervise resulted in a cure rate of 85%.
