The status of tuberculosis infection control among health care workers in healthcare facilities in China

Abstract:

ObjectiveTo analyze the prevalence and risk factors of tuberculosis (TB) infection and TB disease among health care workers (HCWs), and to provide evidence for intensifying control of TB.MethodsA systematic review was applied to analyze the literatures about TB infection control status in healthcare facilities from 1995 to 2010．ResultsThe prevalence of TB infection among Chinese HCWs was 60.4%-62.8%, which was much higher than that of general population;the prevalence of TB disease was also higher than that of general population, the highest prevalence was 6.7/1 000 population/year. A higher risk of acquiring TB disease was associated with many factors, including certain work locations, healthcare facility design, working environment, and personal protective measures.ConclusionTB is a significant occupational problem among HCWs,available evidence reinforces the need to design and implement effective and affordable TB infection control programs in healthcare facilities in China.
