Service years of health professionals are associated with tuberculosis infection control practice in Ethiopian teaching hospital

Introduction: proper tuberculosis (TB) infection control (TBIC) practice of health professionals is one of an effective TB prevention. Despite this reality, the TBIC practice of health care workers was not been well studied. This study assessed the TBIC practice of health professionals and associated factors in Mizan Tepi University Teaching Hospital, southwest Ethiopia. Methods: an institutional-based quantitative cross-sectional study was conducted from September 1 to 30, 2019, by including all health professionals in the hospital. Participants who answered at least 50% of TBIC practice questions correctly were categorized as having good TBIC practice. Binary logistic regression was used to identify factors associated with the practice of the participants. The odds ratio with a 95% confidence interval and p-value was used to measure the strength of association; the significant association was declared at a p-value less than 0.05. Results: the study found that 64.1% (95% CI: 56.6%, 70.7%) of the participants had good TBIC practice. More than half, 102(51.5 %) of study participants have service years of greater than or equal to five years. Only the service year of health professionals was significantly associated [95%CI (AOR= 2.43; 95%CI: 1.28, 4.6)] with the respondents´ TBIC practice. Conclusion: only less than two-third of health professionals had good TBIC practice which is inadequate. And also experienced staff had significantly better TBIC practice. As a result, health professionals in MTUTH should be supported to practice TBIC as routine activity and opportunities should be made for senior staffs to share their TBIC experiences with others.
