The Effect of Pet Insurance on Presurgical Euthanasia of Dogs With Gastric Dilatation-Volvulus: A Novel Approach to Quantifying Economic Euthanasia in Veterinary Emergency Medicine.

Euthanasia of companion animals in veterinary emergency medicine is a common cause of death. Euthanasia is economic when it is the consequence of the pet owner's inability to afford essential treatment while a viable medical alternative to euthanasia exists. Gastric dilatation-volvulus (GDV) is an acute life-threatening emergency condition of dogs; if left untreated, rapid death is highly likely. Surgical treatment leads to survival of around 80-90% of dogs; however, such treatment is costly. Therefore, pre-surgical euthanasia may be largely economically motivated. Having pet insurance, a financial instrument to reduce the burden of unforeseen veterinary medical costs on pet owners, would be expected to abolish the risk for pre-surgical economic euthanasia. We therefore aimed to determine whether pet insurance attenuates the risk of pre-surgical economic euthanasia in dogs with GDV. Non-referred dogs (n = 260) with GDV and known insurance status seen at 24 emergency clinics over a 2-year period were included. Relevant data (e.g., insurance status, age, comorbidities, outcome) were retrospectively extracted from a pet insurer's claim records (insured animals) or from electronic medical records of participating hospitals (non-insured animals). Forty-one percent of dogs (106 of 260 dogs) did not survive to hospital discharge; 82 (77%) of non-survivors died before surgery, all through euthanasia. The pre-surgical euthanasia rate was 10% in insured and 37% in non-insured dogs (p < 0.001). When adjusted for the effect of age, deposit size, comorbidities, and blood lactate concentration, the absence of insurance increased the odds of pre-surgical euthanasia by a factor of 7.4 (95% CI 2.0 to 37; p = 0.002). Of dogs undergoing surgery, 86% survived to hospital discharge. Overall, 80% of insured animals and 53% of non-insured animals survived to hospital discharge (p < 0.001). Thus, insurance was associated with a marked decrease in risk of pre-surgical euthanasia indicating that the cause of pre-surgical euthanasia of dogs with GDV is predominantly economic in nature. The rate of pre-surgical euthanasia in dogs with GDV may emerge as a suitable marker to quantify economic decision making of pet owners and to measure the impact of financial interventions aimed at mitigating economic duress associated with cost of veterinary emergency care.

Presumptive central nervous system cuterebriasis and concurrent protein-losing nephropathy in a dog.

OBJECTIVE: To describe the clinical course and successful management of a dog suspected to have central nervous system (CNS) Cuterebra larval migration and concurrent protein-losing nephropathy (PLN). CASE SUMMARY: A 1-year-old castrated male mixed breed dog was diagnosed with presumptive CNS cuterebriasis based on history, progressively deteriorating mentation, seizures, and magnetic resonance images showing a tubular lesion consistent with a migrating Cuterebra tract. Additionally, serum biochemistry and urine analyses revealed the development of a severe PLN. Surgical removal of the Cuterebra was attempted unsuccessfully, and subsequently, the dog was treated with ivermectin, antihistamines, anticonvulsants, and a tapering dose of glucocorticoids. Over several weeks the dog's neurologic status improved and the PLN resolved completely. NEW OR UNIQUE INFORMATION PROVIDED: This case describes successful management of presumptive CNS cuterebriasis in a dog. It is also, to our knowledge, the first report of PLN associated with cuterebriasis in the veterinary literature.
