Button batteries in the ear, nose and throat: a novel survey of knowledge of UK advanced nurse practitioners.

Background: Button battery (BB) impaction in the ear, nose and throat can result in significant morbidity. Advanced nurse practitioners (ANPs) are increasingly responsible for initial patient assessment and prompt escalation to otolaryngologists for definitive management.

Aim: Our novel national study aimed to assess ANPs' knowledge with respect to the assessment and management of patients with BBs in the ear, nose and throat.
