Diagnostic Relabelling and Concordance in Emergency Departments: A Comment on Mattoo et al. Study.

This letter suggests that relabelling often reflects documentation differences rather than diagnostic error. It highlights higher mismatch rates in paediatric and neurological patients and considers whether improved coding systems or earlier access to investigations could reduce these gaps. Future studies assessing diagnostic confidence at admission and stronger collaboration between emergency and inpatient teams may also help improve concordance.
