Abstract
BackgroundTuberculosis is the leading causes of mortality among infectious diseases worldwide. The risk of transmission from patients to health workers is doubles that of the general population. The close contact to the infectious case before diagnosis is the major risk for tuberculosis infection. The aim of the study was to assess knowledge and practice of health professionals towards tuberculosis infection control and its associated factors in health facilities of Addis Ababa, Ethiopia.MethodsA cross-sectional study was conducted from February 29 to April 15/2014 in selected health facilities in Addis Ababa. Five hundred ninety health workers were included in the study. The sample size was assigned to each health facility proportional to their number of health workers. Study subjects were selected from each stratum by simple random sampling technique. Interviewer administered structured questionnaire was used to collect information. Logistic regression was used to identify factors associated with knowledge and practice of health workers towards tuberculosis infection control.ResultFive hundred eighty two participants with 98.6% response rate were involved in the study. Of these, 36.1% had poor knowledge and 51.7% unsatisfactory practice score towards tuberculosis infection control. Having more than six years working experience in health facility (AOR = 2.51; 95% CI: 1.5-4.1) and tuberculosis related training (AOR = 2.51 95% CI; 1.5, 4.1) were significantly associated with knowledge on tuberculosis infection control. Having experience in tuberculosis clinic (AOR =1.93; 95% CI: 1.12, 3.34) and tuberculosis related training (AOR = 1.48; 95% CI: 1.87, 2.51) were significantly associated with practice on tuberculosis infection control.ConclusionOne third of health workers had relatively poor knowledge and nearly half of them had unsatisfactory practice on tuberculosis infection control. Tuberculosis training and work experiences in health facility are determinant factor to knowledge. Whereas tuberculosis related training and experience in tuberculosis clinic are predictor to practice. So, training of the health professionals, on job orientations of junior health workers, and farther study including private health workers are recommended.
Highlights
Tuberculosis is the leading causes of mortality among infectious diseases worldwide
In the region of Africa and South East Asia, the prevalence of tuberculosis among people living with human immunodeficiency virus (HIV) is estimated to 303 and 264 cases per 100,000 populations respectively and 75% of total TB deaths occurred in these regions in 2012 [2,3]
This study shows that health worker who had first degree and above were 1.49 times more knowledgeable compared to diploma level (AOR = 1.49; 95% CI: 1.47, 2.19) (Table 3)
Summary
Tuberculosis is the leading causes of mortality among infectious diseases worldwide. Tuberculosis (TB) is the leading causes of mortality among infectious diseases in the world [1]. In the region of Africa and South East Asia, the prevalence of tuberculosis among people living with human immunodeficiency virus (HIV) is estimated to 303 and 264 cases per 100,000 populations respectively and 75% of total TB deaths occurred in these regions in 2012 [2,3]. In Sub-Saharan Africa, TB comprises 25% of avoidable adult deaths and the transmission of multi-drug resistant TB (MDR-TB) among HIV-infected individuals in hospitals has been documented with high case-fatality rates [1,2,3,4]. Ethiopia is among the 22 high TB burden countries with 210 cases per 100,000-population TB prevalence and 44 cases per 100,000-mortality rate [2]
