Abstract:
Abstract: Objective To investigate the occurrence of multidrug-resistance among tuberculosis patients in Hainan Province from 2014 to 2020 and to analyze the influencing factors, aiming to provide reference for formulating drug-resistant tuberculosis control strategies in this region. Methods This study collected sputum samples from the patients with pulmonary tuberculosis admitted to the Second Affiliated Hospital of Hainan Medical University from 2014 to 2020, and performed
isolation and identification of Mycobacterium tuberculosis and drug susceptibility testing. After the strains were identified as positive, drug sensitivity tests were conducted, and multi-drug resistant patients were found. Clinical data was retrospectively collected, and chi-square test and unconditioned logistic regression were used to analyze the influencing factors of multidrug resistance. Results A total of 2 672 patients underwent sputum culture, strain identification, and drug susceptibility testing in TB designated hospitals in Hainan Province from January 1, 2014 to December 31, 2020. Among them, 1 942 patients with available drug susceptibility test results and complete clinical data were enrolled, among which 398 cases with drug-resistant TB were included in the case group, and 1 544 cases without drug resistance were included in the control group. Multivariate logistic regression analysis showed that farmers, rural residence, treatment history of retreatment, irregular medication history, number of pulmonary cavities ≥3, and BMI<18.5 were independent risk factors for MDR-TB. The risk of MDR-TB in farmers was higher than that in non-farmers (OR=1.542, 95%CI: 1.150-2.020); patients living in rural areas had a higher risk of multidrug resistance than those living in urban areas (OR=1.445, 95%CI: 1.095-1.907); the risk of MDR in the retreatment patients was higher than that in the initial treatment patients (OR=5.616, 95%CI: 4.250-7.421); the risk of multi-drug resistance in patients with irregular medication was higher than that in patients with regular medication (OR=2.665, 95%CI: 2.012-3.531); the risk of multidrug resistance in patients with pulmonary cavity number ≥3 was higher than that in patients with pulmonary cavity number <3 (OR=5.040, 95%CI: 3.768-6.740); compared with patients with BMI<18.5, patients with BMI=18.5-24.0 and BMI≥24.0 had a lower risk of multidrug resistance (OR=0.735, 95%CI: 0.555-0.975 and OR=0.447，95%CI:0.225-0.888, respectively). Conclusions Retreatment, farmer occupation, rural residence, irregular medication and low BMI may be the risk factors for multidrug resistance in Hainan Province.
