Are routine chest X-rays for students entering university worthwhile?

Abstract Mass radiographic screening for tuberculosis has lost favour in many countries. The aim of this study was to determine whether the continued practice of such screening of prospective students at the University of the West Indies was warranted by assessing the yield and the cost of the programme in our setting. In a cross- sectional retrospective study, 12 662 chest X-ray reports collected over the period 1989–1997 were studied. No active case of tuberculosis was detected. Three students reported a previous history of tuberculosis and 10 students had a positive family history of tuberculosis. Three hundred and ninety-nine clinically insignificant abnormalities were reported, such as mild scoliosis and calcified foci. Routine radiological screening of prospective students at the University of the West Indies for tuberculosis has an extremely low yield, places the students at unnecessary risk of radiation exposure and should be discontinued.
