Field trials of Baby Check: a scoring system to quantify illness in babies under 6 months.

Baby Check, a scoring system for quantifying illness in young babies, was developed from a study of 1007 well and ill babies in Cambridge and Melbourne. This paper describes the setting up of field trials to test the performance of the scoring system when used by mothers, GPs and hospital doctors. Preliminary results suggest that the scoring system is attractive, easy to use, useful and of high specificity. Its sensitivity to serious illness is also thought to be high but this will become clearer when the main hospital field trial has been completed.
