Assessment of Knowledge and Attitude of Tuberculosis Patients in Direct Observation Therapy Program towards Multidrug-Resistant Tuberculosis in Addis Ababa, Ethiopia: A Cross-Sectional Study

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB) is becoming a major challenge of tuberculosis (TB) control program globally but more serious in developing countries like Ethiopia. In 2013, a survey result showed that in Ethiopia, tuberculosis patients from new cases and retreatment cases had resistance to at least isoniazid and rifampicin with a significant increase over time. Inadequate knowledge and wrong perception about MDR-TB by patients were detrimental to TB control programs. The study aimed at assessing the knowledge and attitude of TB patients of direct observation therapy program towards multidrug-resistant tuberculosis in health centres of Addis Ababa, Ethiopia. METHODS: A cross-sectional study was conducted in 10 health centres of Addis Ababa which were selected by simple random sampling technique. A total of 422 TB patients were included in the study, and participants from each health centres were taken proportional to the number of clients in each health centres. Data was entered and analyzed using SPSS version 20. Association between outcome and independent variables was explored using logistic regression. RESULTS: The level of knowledge of TB patients about MDR-TB was poor and only 55.0% of TB patients attained good overall knowledge. A significant association was found between good knowledge and attending tertiary level of education (AOR = 4.3, 95%CI = 1.9, 9.8), gender (AOR = 1.62, 95%CI = 1.1, 2.4), income of respondents' family (OR = 0.4, 95%CI = 0.2, 0.9), and sleeping practice (AOR = 8.0, 95%CI = 4.0, 15.7). Nearly three-fourths (73.5%) of TB patients had a favourable attitude towards MDR-TB. Occupational status (AOR = 4.4, 95%CI = 2.5, 7.6) and sleeping practices (AOR = 2.4, 95%CI = 1.2, 5.0) were significantly associated with the attitude of the TB patients. CONCLUSIONS: Knowledge of TB patients toward MDR-TB was poor. Although a large proportion of patients had a favourable attitude, it still needs to be improved. Hence, efforts should be made to implementing health education to improve awareness of TB patients about MDR-TB.
