Improved management of tuberculosis is a key priority for Public Health England due to unacceptably high rates of the disease in the UK, particularly in London and other major cities. A survey of 20 staff in the acute medical unit at Queen Alexandra Hospital, Portsmouth, explored potential barriers to early TB detection and infection control in busy emergency departments. Low awareness and little familiarity with TB among many emergency admissions staff increased the likelihood of transmission from undiagnosed patients in crowded waiting areas. The study suggested regular updates on TB so staff could refresh their knowledge and awareness, and help improve TB detection and infection control.
