Abstract
The emergence of drug-resistant tuberculosis (TB) is a major public health threat. However, little is known about the predictors of death in drug-resistant TB in Malaysia. This study aimed to determine the predictors of death in drug-resistant TB patients, including multidrug-resistant TB (MDR-TB), in Kuala Lumpur, Malaysia. This study adopted a retrospective cohort study design and involved laboratory-confirmed drug-resistant TB patients (n = 426) from January 2009 to June 2013. A Cox regression model and Kaplan-Meier curves were used to model the outcome measure. Data were analysed by using SPSS v.20.0 for Windows. In this study, 15.3% (n = 65) of the patients died. Among the study patients, 70.9% were monoresistant TB cases, 9.4% were poly-resistant TB and 19.7% were MDR-TB. MDR-TB [adjusted hazard ratio (aHR) = 2.23, 95% confidence interval (CI) 1.26-3.95], ethnicity [Malay (aHR = 5.95, 95% CI 2.30-15.41), Chinese (aHR = 4.01, 95% CI 1.38-11.66) and Indian (aHR = 3.76, 95% CI 1.19-11.85)], coronary heart disease (aHR = 6.82, 95% CI 2.16-21.50), drug abuse (aHR = 3.79, 95% CI 2.07-6.93) and treatment non-compliance (aHR = 1.81, 95% CI 1.01-3.27) were independent predictors of poorer survival in the multivariate Cox regression analysis. This study suggests that MDR-TB, local ethnicity, coronary heart disease, history of drug abuse and treatment non-compliance are factors predicting poor survival in drug-resistant TB patients. More emphasis should be given to the management of drug-resistant TB patients with these characteristics to achieve better treatment outcomes.
