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 is no published information regarding multidrug-resistant tuberculosis in the Tigray region. Therefore, the aim of this study was to assess the determinants of multidrug-resistant tuberculosis among adults undergoing treatment for tuberculosis in the Tigray region, Ethiopia.
Methods: Hospital-based unmatched case-control study was conducted from April to June 2019. A Simple random sampling method was used to select the required number of sample size. Primary data was collected from cases and controls by face-to-face interviews using pretested structured questionnaires. The binary logistic regression model was used to test the association between independent and dependent variables. Variables at p-value less than 0.25 in bivariate analysis were entered into a multivariable analysis to identify the determinant factors of multidrug-resistant tuberculosis. Finally, the level of significance was declared at a p-value <0.05.
Results: A total of 254 participants with 85 cases and 169 controls were included in this study. 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 multidrug resistance tuberculosis.
Conclusion: Rural residence, HIV, relapses, return after lost follow up and treatment failure were the identified determinant factors of multidrug-resistance tuberculosis.
