Abstract
A bacterium called Mycobacterium tuberculosis which affected the CNS has caused the emergence of CNS tuberculosis which covered approximately 15% of the total cases of extra-pulmonary TB cases. The first phase of this study was intended to determine the level of KAP on CNS tuberculosis among healthcare workers as well as its associated factors and to determine the association between KAP and self-sufficient perception among the HCWs towards the disease. This study sequentially also explored the themes that influence KAP on CNS tuberculosis prevention among the HCWs in the second phase. A two-phase mixed methods study approach was used in this cross-sectional study underpinned by positivism paradigm. A total of 134 HCWs from medical wards, neurology wards and forensic units of Hospital USM and HKL participated in phase one which were evaluated by using a newly developed self-administered questionnaire of KAP. In phase two, a number of 21 HCWs participated in four focus group discussions by using a semi-structured interview guide. Data collected from first phase was analysed by using logistic regression while in phase two, generation of themes was applied through thematic analysis. In phase one, the profile of HCWs showed that their mean (SD) age was 33.0(9.2) year-old who have worked about 7.0(9.0) years in median (IQR). Out of 134 HCWs, 56.7% had good knowledge on CNS tuberculosis while majority of them, 53.7% had negative attitude and there was no difference in their level of practice. The healthcare workers’ age and duration of employment were associated by both 5% times the likelihood on getting poor knowledge while respectively by 4% and 5% times the likelihood to have negative attitude towards CNS tuberculosis. In the meantime, age of HCWs and their workplace of neurology ward were associated respectively by 4% more likely and 96% less likely to have poor practice. The associated factors of self-sufficient knowledge perception of HCWs were their negative attitude and duration of employment respectively by 65% less likely and 6% more likely to perceive themselves as having sufficient level of knowledge on CNS tuberculosis. In the second phase, the factors of transmission of CNS tuberculosis and the willingness of HCWs affected their KAP towards the disease prevention. Despite the rare occurrence of admitted patients with CNS tuberculosis, the HCWs unexpectedly gain good knowledge on the disease although majority of them presented with negative attitude which depicted by their way of thinking and reacting while handling the CNS tuberculosis patients.
