Methods and materials
A retrospective multicentre cohort study of patients presenting to Eastern Health Emergency Departments was conducted between January 2010 to December 2015.
Ethics approval was obtained from the Office of Research and Ethics,
Eastern Health.
Reference number: LR08/2016.
Out of the 167 patients who presented to the emergency departments with suspected fish or chicken bone impaction,
96 patients were included in the study (figure 1).
Electronic and paper records from the emergency departments and hospital wards were accessed to obtain various variables.
The gold standard of diagnosis was defined as direct visualisation by either flexible nasoendoscopy by the bed-side,
or direct laryngoscopy in theatre or in the emergency department.
All imaging was formally reported by a consultant radiologist.
Sensitivities and specificities were calculated for the radiological investigations.
The demographic variables underwent statistical analysis (table 1).
