Plain-English summary
A group of 70 cats with acute kidney injury (AKI) was studied to find out what factors could predict their chances of survival. The research found that older cats with lower levels of certain blood components, like albumin and white blood cells, were less likely to survive. Interestingly, a drop in blood urea and creatinine levels within three days was linked to better outcomes. A new scoring system was developed to help predict survival based on body temperature and specific blood tests, showing promising accuracy. Unfortunately, the overall survival rate was low, with 64% of the cats not making it.

Abstract
BACKGROUND: The clinical manifestations of acute kidney injury (AKI) range from mild to fatal in cats; however, prognosis factors have been rarely studied. HYPOTHESIS/OBJECTIVES: To find the clinical factors significantly correlated with the outcome among cats with AKI and to develop a simple prognostic index. ANIMALS: Seventy cats with AKI were recruited. METHODS: Demographic and clinicopathological data obtained from 70 cats with AKI were retrospectively collected. Student's t-test or Mann-Whitney U-test and Pearson chi-square test or Fisher's exact were applied to determine the factors associated with survival in cats with AKI. Using logistic regression, the statistically significant factors associated with prognosis were identified and a new prediction model was generated. RESULTS: The overall case fatality rate was 64% (45/70). The results showed that nonsurviving cats had significantly lower levels of PCV, WBC, RBC, LDH and albumin, a lower albumin/globulin ratio, lower blood glucose, and a reduced body temperature, as well as being older. Serum urea and creatinine concentrations were not statistically significant as prognostic factors, but a decrease in these 2 variables in 3 days was significantly related to a reduction in death. A summary prognostic index including body temperature and LDH and albumin concentrations had area under the receiver-operating characteristic curve (AUROC) for predicting death of 0.86 (P < .05) and a cut-off value of 0.82, a sensitivity of 77% and a specificity of 90%. CONCLUSIONS: The prognosis in cats with AKI is quite different from that found for human and dogs.
