A 4-year review of human bite injuries presenting to emergency medicine and proposed evidence-based guidelines

Human bite injuries are a common injury, roughly accounting for around 0.1% of attendances to Emergency Medicine departments. Morbidities associated with such injuries are legion. Of paramount importance is the potential for infection of the wound site, both bacterial and viral.A retrospective 4-year review of 3136 case notes was conducted, identifying 421 human bites. This amounts to one every 3 days! The majority of those bitten were young males (male:female ratio = 3:1; 44% comprising the age group 16–25 years).The management of these wounds was found to be poor. 17% of patients did not receive any antibiotic cover; 21% of patients either did not have tetanus prophylaxis administered when required or had a tetanus booster when they were already covered; 34% of patients either did not receive a hepatitis B booster when one was required or received one when they were already covered.This lack of effective documentation, along with errors in addressing prophylaxis of the infective agents, may have profound medico-legal consequences.The author believes that the findings will be reproduced in other centres and in view of the inadequacies highlighted by this work, it is necessary to introduce an evidence-based protocol for the comprehensive management of the human bite. Using United Kingdom Department of Health evidence-based guidelines, the author proposes such a pathway.
