Background: Acute Patient Physiologic and Laboratory Evaluation (APPLE) scores have not been reported in cats with diabetic ketoacidosis (DKA). Hypothesis: In cats with DKA, APPLE scores will be significantly higher in non‐survivors compared with survivors and these scores will predict mortality. Animals: Sixty‐eight cats with DKA. Methods: Retrospective study. The APPLE scores, blood glucose concentration (BG), venous pH, and ketone concentrations were compared between survivors and non‐survivors. Simple logistic regression was used to determine if these variables predict the binary variable of survival or non‐survival, and if they did, an empirical optimal cut point for mortality prediction was calculated. Results: The APPLEfast and APPLEfull scores were significantly higher in non‐survivors (30 cats; 24.6±7.4 and 45.2±7.3, respectively) compared with survivors (38 cats; 20.9±6.2 and 41.7±6.5; P =.01 and P =.02, respectively). The APPLEfast (P =.03) but not the APPLEfull scores (P =.06) predicted mortality. For every 1 unit increase in the APPLEfast score, the odds of death increased by 1.08 (95% confidence interval [CI], 1.006‐1.17; P =.03). Median BG was significantly higher in non‐survivors (431 mg/dL; range, 260‐832 mg/dL) compared with survivors (343 mg/dL; range, 256‐738 mg/dL; P =.01) and BG predicted mortality (P =.02). For every 1 mg/dL increase in BG, the odds of death increased by 1.004 (95% CI, 1.0006‐1.008). Empirical optimal cut points for APPLEfast and BG mortality prediction were 24.5 and 358 mg/dL, respectively. Conclusions and Clinical Importance: The APPLEfast score and BG predict mortality in cats with DKA and can be used to stratify populations by risk of mortality in clinical trials of DKA in cats.
