Abstract
Background
Tuberculosis is among major public health problems throughout the world and leading cause of death
among curable infectious disease. The World Health Organization lists Ethiopia as one ofthe 30 high
burden tuberculosis, tuberculosis/HIV and multidrug resistant tuberculosis countries in 2018.
Strengthening tuberculosis patient’s knowledge about tuberculosis and treatment are believed to
improve tuberculosis treatment adherence. Studies on the role of patient’s knowledge on tuberculosis
treatment adherence are limited.
Objective: The objective of this study was to assess the role of patient’s knowledge about tuberculosis
on treatment adherence in public health facilities in Yeka Sub city, Addis Ababa, 2019
Methods: A facility based cross sectional study was conducted in Yeka sub city, Addis Ababa. Data
were collected from sample of 256 patients receiving tuberculosis treatment. Mean score described
knowledge about tuberculosis as good or poor when above and below the mean respectively, while
adherence to tuberculosis treatment was measured using MoriskyMedication Adherence Scale
(MMAS) with eight item scoredata were analyzed using SPSS version 20 for window.
Results:The result showed that 36.7% (95%CI: 30.9-42.6) of tuberculosis patients havegood
knowledge about tuberculosis,while 28.9% (95%CI: 23.8-34.8) have good knowledge about
tuberculosis treatment. Tuberculosistreatment adherence level was79.3 % (95%CI: 74.2-84). Patients
who have good knowledge about tuberculosis disease were 2.7 times (AOR =2.7, 95% CI: 1.04-7.3)
more likely to adhere to tuberculosis treatment compared to those with poor knowledge. Study
participants who have good knowledge about tuberculosis treatment were no significant difference
compared to those who have poor knowledge (AOR= 0.6, 95%CI: 0.20-1.78).
Conclusion and recommendation:The level tuberculosis treatment adherence observed in this study
is comparable with a previous study conducted in Addis Ababa. The study showed that respondents
who had good knowledge about tuberculosisare more likely to adhere to tuberculosis treatment. Thus,
implementation of comprehensive interventions, focusing on knowledge of tuberculosis patients about
tuberculosis disease and transmission of tuberculosis, is important to enhance tuberculosis treatment
adherence.
