Epidemiology of factors associated with detection and treatment outcomes of patients with Smear positive pulmonary tuberculosis: A Population Based study using univariate and Multivariate analysis

Tuberculosis is an acute/chronic، infectiousand necrotizing disease which involves different organs of the body particularly the lungs. Since case finding and treatment of people infected with smear positive pulmonary tuberculosis has been highlighted in national and global goals، this study aimed to provide effective suggestions to improve the status of existing، through epidemiological study of smear positive pulmonary tuberculosis patients.

the present study was carried out descriptiveandanalytical availabledata. Â check list consisting of variables such as age، gender، nationality، place of residence، result of mucus smears at the beginning of treatment، at the end of the second month of treatment and at the end of treatment، was used for data collection. Data analysis was carried out by Ëxcel and SPSS 16، using descriptive statistics and univariate and Multivariate regression.

1296 tuberculosis cases were identified in the study period، of which 48. 2 percent were smear positive pulmonary tuberculosis، 24. 5 percent were smear negative pulmonary tuberculosis and 27. 3 percent were Ëxtra-pulmonary tuberculosis. The incidence of smear positive pulmonary tuberculosis was 4. 3 in one hundred thousand of the population. 57. 5 percent of the identified smear positive pulmonary tuberculosis were male and the mean age of them was 49. 67 ± 21. 60. Çonclusion: Ëpidemiological pattern observed in this study is consistent with other similar studies. Ïn order to achieve millennium development goal (50 percent decrease in tuberculosis prevalence and eliminating the disease up to the year 2050)، and national goals of tuberculosis control program، education، case finding and on time treatment of the smear positive pulmonary tuberculosis patients should be considered at all levels of the health network as well as private sector and physicians'' offices.
