Outcome prediction in dogs admitted through the emergency room: Accuracy of staff prediction and comparison with an illness severity stratification system for hospitalized dogs.

Objective: To determine whether emergency staff and students can predict patient outcome within 24 hours of admission, comparing the accuracy of clinician prognostication with outcome prediction by Acute Patient Physiologic and Laboratory Evaluation (APPLE) scoring and identifying whether experience or mood would be associated with accuracy.

Design: Prospective observational study between April 2020 and March 2021.

Setting: University teaching hospital.
