RESUMO
OBJECTIVES: To devise a veterinary triage list (VTL) and to determine whether the application of this VTL results in more accurate categorization of emergency patients compared with intuitive triage. DESIGN: Prospective and retrospective observational study. SETTING: Private veterinary emergency clinic. ANIMALS: Four hundred and eighty-five client-owned dogs and cats. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A VTL was composed using a human triage system and data from medical records of the study group. Target waiting times were prospectively determined using intuition by veterinary nurses (TWT-N). Target waiting times were subsequently determined retrospectively by the use of the VTL (TWT-VTL). Both TWT-N and TWT-VTL were compared against target waiting times determined by a review team (TWT-R), which was considered the gold standard. TWT categories included 0, 15, 30-60, and 120 minutes, and were associated with triage categories red, orange, yellow, and green, respectively. Differences in agreement were tested for significance. One hundred and eighty-five dogs and 300 cats fulfilled the inclusion criteria. TWT-N and TWT-R agreed on 30 cases of 67 (44.8%) in triage category red and 22 of 89 (24.7%) in category orange. TWT-VTL and TWT-R agreed on 64 cases of 67 (95.5%) in category red and 75 of 89 (84.3%) in category orange. Agreement between TWT-VTL and TWT-R (Pearson's R = 0.848) was significantly greater (P < 0.001) than agreement between TWT-N and TWT-R (Pearson's R = 0.519). CONCLUSIONS: Intuitive triage performed by veterinary nurses showed significantly less correlation with TWT-R than triage performed with the VTL. A short physical examination in all emergency patients appears to be essential in recognizing critical disease. The use of a standardized VTL can help to categorize veterinary emergency patients.
