Abstract: This study aims to examine the concept of 'inappropriate' emergency department attendances in relation to the emergency department at Christchurch Hospital. It specifically seeks to determine whether there is a consensus opinion among healthcare providers regarding a definition of 'inappropriate'. An exploratory survey of health professionals involved with the referral, assessment, transport, and treatment of emergency department patients in Christchurch was carried out. A range of health professionals, including ambulance personnel, general practitioners, emergency department physicians, emergency nurses, and hospital managers were approached. A series of questions relating to definition and response to 'inappropriate' patients was asked, with an additional open-ended question relating to the definition of 'appropriateness'. The researchers found significant differences in the attitudes and perceptions of key health professionals involved in the referral, treatment, and admission of patients to the emergency department. This has implications for any interventions aimed at addressing emergency department 'overcrowding' that assume the presence of a consensus understanding of this concept.
