Using a pacifier to decrease sudden infant death syndrome: an emergency department educational intervention.

Background. Pacifier use decreases the risk of sudden infant death syndrome (SIDS). An emergency department (ED) visit may provide an opportunistic 'teachable moment' for parents.

Is the interpretation of rapid antigen testing for respiratory syncytial virus as simple as positive or negative?

Objective: To measure the performance characteristics of an immunochromatographic rapid antigen test for respiratory syncytial virus (RSV) and determine how its interpretation should be contextualised in patients presenting to the emergency department (ED) with bronchiolitis.

Design: Diagnostic accuracy study of a rapid RSV test.

Setting: County hospital ED.
