Original publication title: Long-term outcome of cats and dogs with acute kidney injury treated with intermittent hemodialysis: 135 cases (1997-2010).
Plain-English summary
A group of 135 cats and dogs with acute kidney injury (AKI) received intermittent hemodialysis (IHD) to help their kidneys recover. While the survival rates were low during hospitalization—50% for cats and 53% for dogs—those that made it home had a better chance of living longer. After 30 days, about 48% of cats and 42% of dogs were still alive, and after a year, 38% of cats and 33% of dogs had survived. This suggests that while AKI can be serious, treatment with IHD can lead to improved long-term outcomes for pets that survive the initial crisis.

Abstract
OBJECTIVE: To determine the long-term outcome for small animal patients with acute kidney injury (AKI) treated with intermittent hemodialysis (IHD). DESIGN: Retrospective case series. ANIMALS: 42 cats and 93 dogs treated with IHD for AKI. PROCEDURES: Medical records of cats and dogs treated with IHD for AKI from January 1997 to October 2010 were reviewed. Standard methods of survival analysis with Kaplan-Meier product limit curves were used. The log-rank, Mann-Whitney, and Kruskal-Wallis tests were used to determine whether outcome, number of IHD treatments, or duration of hospitalization was different when dogs and cats were classified according to specific variables. RESULTS: The overall survival rate at the time of hospital discharge was 50% (21/42) for cats and 53% (49/93) for dogs. The overall survival rate 30 days after hospital discharge was 48% (20/42) for cats and 42% (39/93) for dogs. The overall survival rate 365 days after hospital discharge was 38% (16/42) for cats and 33% (31/93) for dogs. For all-cause mortality, the median survival time was 7 days (95% confidence interval, 0 to 835 days) for cats and 9 days (95% confidence interval, 0 to 55 days) for dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Cats and dogs with AKI treated with IHD have survival rates similar to those of human patients. Although there was a high mortality rate prior to hospital discharge, those patients that survived to discharge had a high probability of long-term survival.
