The Impact of a Tick-Sheet in Improving Interpretation Accuracy of Chest Radiographs by Non-Specialists in an HIV positive cohort

Study objective
3.1 Primary objective
To determine if the application of a tick-sheet after four hour training on its use and on CXR
interpretation, improves the interpretation accuracy of CXRs for active TB, by nonspecialists,
in an HIV-positive cohort.
3.2 Secondary objective
To determine whether the application of a tick-sheet reduces the inter-reader variability of
CXR interpretation in a group of non-specialists by comparing the inter-reader agreement
before and after intervention.
