OBJECTIVES: To determine treatment outcomes and associated predictors of all patients registered in 2012 with the Malaysian National Tuberculosis (TB) Surveillance Registry.
METHODS: Sociodemographic and clinical data were analysed. Unfavourable outcomes included treatment failure, transferred out and lost to follow-up, treatment defaulters, those not evaluated and all-cause mortality.
RESULTS: In total, 21 582 patients were registered. The mean age was 42.36 ± 17.77 years, and 14.2% were non-Malaysians. The majority were new cases (93.6%). One fifth (21.5%) had unfavourable outcomes; of these, 46% died, 49% transferred out or defaulted and 1% failed treatment. Predictors of unfavourable outcomes were older age, male sex, foreign citizenship, lower education, no bacille Calmette-Guérin (BCG) vaccination scar, treatment in tertiary settings, smoking, previous anti-tuberculosis treatment, human immunodeficiency virus infection, not receiving directly observed treatment, advanced chest radiography findings, multidrug-resistant TB (MDR-TB) and extra-pulmonary TB. For all-cause mortality, predictors were similar except for rural dwelling and nationality (higher mortality among locals). Absence of BCG scar, previous treatment for TB and MDR-TB were not found to be predictors of all-cause mortality. Indigenous populations in East Malaysia had lower rates of unfavourable treatment outcomes.
CONCLUSIONS: One fifth of TB patients had unfavourable outcomes. Intervention strategies should target those at increased risk of unfavourable outcomes and all-cause mortality.
This study aims to determine tuberculosis incidence, all-cause mortality, and its associated factors among health care workers (HCWs) registered in 2012 to 2014 with the Malaysian National Tuberculosis (MyTB) Surveillance Registry. Regression analysis was used to determine factors associated with all-cause mortality. Incidence rates ranged from 135.18 to 156.50/100 000 and were higher for HCWs compared with the general population (risk ratio = 1.70-1.96). The mean age at notification was 34.6 ± 10.55 years; 68.9% were female. Most were paramedics (44.3%) followed by other HCWs (41.9%) and doctors (13.8%). Nearly a quarter (23.8%) had extrapulmonary tuberculosis. There were 23 deaths giving a case fatality rate of 2.4%. Factors associated with death were older age (odds ratio [OR] =1.05; confidence interval [CI] =1.01-1.10), diabetes (OR = 3.83; CI = 1.32-11.08), HIV positivity (OR = 18.16; CI = 4.60-71.68), and not receiving directly observed therapy (DOTS) (OR = 10.97; CI = 3.61-33.38). It is important for HCWs to be aware of these increased risks and for authorities to implement protective measures.
