Imported disease in emergency departments: an undiscovered country?
BACKGROUND
The incidence of imported disease within the emergency department (ED) is not known, but a significant number of patients present to medical services after return from traveling. Unless practitioners in ED are aware of the potential for nonendemic disease in the population of patients they attend, there is a possibility that imported diseases will not be diagnosed in the acute setting.


METHODS
A questionnaire was sent to all medical practitioners involved in assessing patients presenting to the EDs of hospitals. This questionnaire consisted of five clinical scenarios describing acute presentations of imported diseases but without a travel history included. Responses were requested to ascertain whether practitioners would elucidate the travel history and consequently establish the correct diagnosis.


RESULTS
A response rate of 96% was achieved. When presented with a clinical scenario suggesting imported disease, travel history is only elicited in 16% of cases by the acute care practitioners. A correct diagnosis was given in 22% of responses. Interestingly, there was generally no significant correlation between eliciting a travel history and establishing the correct diagnosis.


CONCLUSIONS
When presented with a clinical scenario that describes an imported disease, medical practitioners in EDs do not routinely establish a travel history or consider the diagnosis of imported disease. There may be a high potential for imported disease to be missed in the ED.
