Analysis Of Epidemiological Characteristics And Control Of Tuberculosis In Anhui Province

ObjectiveAssessment of epidemiological features of tuberculosis patients in Anhui Province, drawing a full picture of the current Epidemic Status of Tuberculosis diseases and its development trend, locating key areas and groups where TB diseases are most likely to spread. Assessing the results from the DOTS strategy of Prevention and Intervention on TB diseases that had been implemented in recent years,Planning for the next 5-year disease Prevention and Intervention in Anhui province.MethodTB patient information whose registered or reported current address were four districts in Anhui Province were exported from ‘TB Information Management System(TBIMS)’ during 2005 and 2012 to EXCEL for combination and clean. EXCEL was used to calculate incidence and registered rate, then prepare related statistical tables and graph. SPSS 13.0 was used to analyze data and merge annual population data in Anhui Province.ResultThe reported TB incidence from 2005 to 2012 was 79.86/100,000, 79.30//100,000, 77.46/100,000, 74.14/100,000, 68.88/100,000, 62.17/100,000, 59.33/100,000 and 60.69/100,000, average rate was70.28/100,000. Reported incidence of smear-positive TB patient was 51.81/100,000, 50.60/100,000, 48.74/100,000, 48.61/100,000, 45.71/100,000 40.45/100,000, 34.93/100,000 and 23.74/100,000, average rate was43.15/100,000. average rate was 27.70/100,000. Reported TB death rate was 0.24/100,000, 0.16/100,000, 0.19/100,000, 0.23/100,000, 0.17/100,000, 0.15/100,000,0.14/100,000 and 0.179/100,000, average rate was 0.18/100,000. In Geographic Distribution 16 cities are all reported to have TB diseases; heifei, fuyang, anqing are amongst those with the most patients, which are numbered 45662,42644,33907 patients separately; Tongling, hefei, huaibei are with the high incidence rates, In which Tongling is the highest 116.67/100,000, huangshan area is with the lowest incidence rate which is 53.36/100,000.March and April are the peak season for TB disease spreading every year, the reported numbers of TB patients decreased every month from March onwards and bottomed at January every year.The male to female ratio as indicated from the report is 2.75:1 which was resulted from 250588 male patients versus 91091 females patients. Agricultural Peasants, w-orkers and students are the 3 groups of population with the highest incidence rat-es, which are numbered 260421(76.22%)、17515(5.13%)and 12299(3.60%). TB patients are mostly aged above 15 which contribute to 99.47% of the total patients; the reported incidence rates are in positive correlation with age, peaked at 245.64 per 100,000 population which is from the group aged 65-74.In the past 8 year, Institutions of different levels for TB prevention had registered and treated over 341679 patients, cured 307376 patients, reduced 84534 deaths, avoid infection of 1549087 potential patients, prevented TB from 154909 potential active tuberculosis patients, saved medical spending by 105,530,000 Yuan, Saved social total value worth 22,896,000,000 Yuan, achieving great economical and social benefits, cost-effectiveness ratio 52.ConclusionThe TB Epidemic in Anhui Province has been declining. Being a male in gender, aging, spring season are the factors that may had caused high incidence rates, therefore, intensive measures of disease prevention should be implemented targeting the stated relating groups of people.Significant achievements had been made by DOTS strategy inTB disease control, centralized management of TB diseases had resulted in good returns and cost-effectiveness of both medical and social benefits.In the newly developed 3 dimensional preventive measures to bring the DOTS effectiveness to a higher level. promote DOTS strategy to be carried out in instituations of different municipal levels combined with human resourse management between different departments to ensure a newly patterned TB disease preventive system are in place supported by academic research to probe for new methodologies of TB disease preventions, improving diagnosis of Negative pulmonary tuberculosis.
