Determinants Of Multidrug Resistant Tuberculosis Among Adultsundergoing Treatment For Tuberculosis In Tigray Region, Ethiopia: A Case Control Study
Abstract Background Multidrug-resistant tuberculosis is a type of tuberculosis that is resistant to at least the first line anti-tuberculosis drugs namely, Rifampicin and Isoniazid. Multidrug-resistant tuberculosis has continued to be a challenge for tuberculosis control globally. Globally 600,000 people were newly eligible for Multidrug-resistant tuberculosis treatment with an estimated 240,000 deaths annually. There are few numbers of multi drug resistant tuberculosis studies in different regions of Ethiopia. However, most of these studies were restricted only to a single hospital and there is no published information regarding multi drug resistant tuberculosis in Tigray region. Therefore, the aim of this study was to assess the determinants of multidrug resistant tuberculosis among adults undergoing treatment for tuberculosis in Tigray region, Ethiopia.Methods A hospital based unmatched case control study was conducted from April to June, 2019. Simple random sampling method was used to select 85 cases and 169 controls. Primary data was collected by face-to-face interview and secondary data by reviewing patients’ charts using pretested structured questionnaires. The data were entered and cleaned using Epi data manager then exported to SPSS for analysis. Binary Logistic regression model was used to test the association between independent and dependent variables. Model fitness was checked using Hosmer-Lemeshow goodness-of-fit and Variance inflation factor was used to assess multi collinearity between the independent variables. Variables at p-value less than 0.25 in bivariate analysis was entered into a multivariable analysis to identify the determinant factors of multi drug resistant tuberculosis. Finally, level of significance was declared at p-value <0.05.Results A total of 254 participants with 85 cases and 169 controls were included in this study. Of the respondents, 62 (36.7%) among the controls and 48 (56.5%) among the cases were living in rural residence. Rural residence [AOR=2.54;95%CI=1.34,4.83], HIV[AOR=4.5;95%CI=1.4,14.2], relapse [AOR=3.86;95%CI;1.98,7.5], return after lost follow up [AOR=6.29;95% 1.64,24.2], treatment failure [AOR=5.87; CI=1.39,24.8] were among the determinants of Multi drug resistance tuberculosis.Conclusion Rural residence, HIV, relapse, return after lost follow up and treatment failure were the identified determinant factors of Multi drug resistance tuberculosis.
