Abstract
Objective
To study the accuracy of emergency department admission diagnosis and the effect of investigations on diagnostic accuracy.
Design
Retrospective study in a two-month period.
Setting
Accident & Emergency Department of a public general hospital, which had four in-patient specialties – Medicine, Surgery, Paediatrics and Orthopaedics.
Subjects
All cases admitted through the emergency department in the study period.
Main outcome measures
Degree of correlation between emergency department admission diagnosis and hospital discharge diagnosis.
Results
Of all admission diagnoses, 71.4% fully or partially matched the final discharge diagnoses. The accuracy of diagnosis was statistically better in traumatic cases, the male sex and young adults. Diagnostic accuracy varied with the specialty involved and investigations taken.
Conclusion
History and physical examination remained the most important diagnostic tools in the emergency department. In general, simple investigations available at the emergency department were not helpful in improving diagnostic accuracy.
