The Hunter Area Toxicology Service is a regional toxicology unit situated at the Newcastle Mater Misericordiae Hospital that services a population of about 350 000 people and is a tertiary referral centre for a further 150 000 [23]. All poisoning presentations to emergency departments in the region are either admitted to the unit or notified to the Hunter Area Toxicology Service and entered prospectively into a clinical database. A validated preformatted admission sheet is used by medical staff to record the history and physical examination at the time of admission [24].

There was no review or further information retrieved from medical records after formulation of the research question. (more…)
