Has Symptom-Based Admission Replaced Diagnosis in the Emergency Department? An 18-Year Review of Emergency General Surgical Admissions at Royal Perth Hospital.

Background: Classical medical teaching has made a clear distinction between signs and symptoms, and diagnosis. However, at the time of ward admission, a diagnosis may remain unclear. We propose administrative pressures during the admission process may have reduced the ability for pathological diagnosis. This may result in increased hospitalisation for investigation of signs and symptoms, rather than for treatment of clear diagnoses. We sought to further clarify this hypothesis and investigate changes in the nature of admissions during the last two decades in an adult emergency general surgery service.

Methods: A retrospective analysis of emergency general surgical admissions during four six-month time periods, between 2000 and 2018, was conducted. The six-month periods were spaced evenly during the 18-year study. Demographic information, emergency department length of stay, incidence of a pathological diagnosis on ward admission and accuracy of admission diagnosis were analysed.

Results: 2763 patients were admitted in the four six-month time periods. A significant reduction in number of patients admitted with a pathological diagnosis was noted between the 2012 and 2018 study periods (p < 0.05), with 21.2% of patients admitted in 2018 for investigation of signs and symptoms. The incidence of an accurate admission diagnosis (as assessed by the discharge diagnosis) ranged from 62.3 to 63.6% and did not differ significantly by year.

Conclusion: Between 2012 and 2018, there was a significant increase in the number of emergency general surgical patients admitted for investigation of signs and symptoms. However, accuracy of admission diagnosis was unchanged during the study period.
