NASAN Benchmark Report
The National Audit for Small Animal Neutering (NASAN) is a simple audit that allows veterinary teams to measure post-operative complication rates for the neutering of small animals.
By collecting this donated data, NASAN provides a system to measure national benchmarks for the outcomes of canine, feline and rabbit spays and castrations. The data is combined, analysed manually on an annual basis, and made publicly available to allow practices to compare their rates against the national benchmark.
