Infection control measures are not always implemented even when HCWs are well informed. Insufficient studies were found that examine the level of knowledge, attitude and practice about TB infection control mechanisms among medical laboratory professionals in Ethiopia. Objectives: - To assess knowledge, attitude and practice of TB infection control among medical laboratory professionals in selected DOTS providing health facilities under Addis Ababa City Administration Health Bureau, Addis Ababa, Ethiopia. Methods: Cross sectional study was conducted in Addis Ababa between September 2014 and May 2015 on 213 Medical Laboratory professionals in selected DOTS providing government health facilities. Pre-tested and self-administered questionnaire were used. Data entry and analysis was performed by using SPSS version 20 software. Descriptive statistics, bivariate and multivariate analysis were made. The level of statistical significance was set at p<0.05. Results: A total of 213 participants filled the questionnaires (response rate were 95.9%) the mean knowledge score was 7.69± (SD 2), mean attitude score were 44.63± (SD 4) and mean practice score were 10.56± (SD 2.75).Statistically significant association were observed between total knowledge and last training (AOR=5.03, 95%CI=2.129, 11.901) and presence of TB manual (AOR=0.108, 95%CI=0.037, 0.315). Total attitude score had significant association with level of health facility (AOR=2.715, 95%CI=1.262, 5.841). Total practice score had significant association with the duration last training obtained (4.77, 95%CI=2.173, 10.472). Conclusion: About 33.3% of the study participants had poor knowledge, 46.9% of them had negative attitude and 41.8% of them had poor attitude. Total knowledge score had significant association with last training, presence of TB manual and overall practice score. Total attitude score had significant association with level of health facility. Total practice had significant association with last training. Mean difference were observed between hospital and health center for knowledge but not for attitude and practiceenAttitudeHealth FacilitiesThesis
