This study represents the first attempt to systematically audit the accuracy of AIR data at the national level since 2001. Of the 905 records included in the final analysis, 86% were assessed as accurate (truly overdue) and 14% as inaccurate (i.e. the child appeared overdue despite being actually up to date for the relevant antigen). The error rate ranged from 3% in Victoria to 29% in New South Wales.
