Knowledge and practice on tuberculosis infection control among healthcare workers in Lembah Pantai district, Kuala Lumpur

Introduction: Tuberculosis (TB) is the leading cause of mortality among infectious diseases in the world. Healthcare workers (HCWs) are among the high risk groups of getting TB and the prevalence is double that of the general population. This is due to workplace exposure to TB patients, without adequate TB infection control practices. In Malaysia, the number of TB cases among HCWs has increased from year to year, however TB infection control (TBIC) knowledge and practice remain poor. Objectives: To assess the level of knowledge and practice on TB infection control among HCWs and to determine the associated factors and predictors of good knowledge and practice. Methodology: A cross sectional study involving a simple random sampling from healthcare workers in Lembah Pantai district has been conducted. Self-administered questionnaire has been given to respondent after consent taken. Results: Of 415, 320 (77%) respondents participated in this study. The percentages of respondents having good knowledge and practice on TB infection control are 70.6% and 51.6% respectively. STPM/diploma educational level (AOR=2.325, 95%CI=1.145-4.722), family history of TB infection (AOR=3.882, 95%CI=1.021-14.765), doctor/specialist (AOR=5.022, 95%CI=1.224-20.600) and health clinic (AOR=4.504, 95%CI=2.050-9.892) are the significant predictors of good knowledge while STPM/diploma educational level (AOR=2.055, 95%CI=1.065-3.964), married/widow status (AOR=2.616, 95%CI=1.487-4.603) and maternal and child health clinic (AOR=3.479, 95%CI=1.700-7.118) are the predictors of good practice on TB infection control. Conclusion: One third and half of the respondents have poor knowledge and practice on TB infection control respectively. Training that emphasizes on hands-on skills need to be strengthen to ensure good knowledge and practice on TB infection control among HCWs.
