Owners of seriously ill pets at risk of stress, anxiety and depressive symptoms

This 'caregiver burden' may also lead to increased veterinarian stress, say the authors.

Research on human caregiving describes 'caregiver burden' as a response to problems and challenges encountered while providing informal care for a sick family member. But little is known about the impact of caregiver burden on owners of animals with chronic or terminal diseases -- and the veterinarians who care for them.

So a team of researchers, led by Mary Beth Spitznagel at Kent State University in Ohio, set out to assess caregiver burden and psychosocial function in 238 owners of a dog or cat.

They compared 119 owners of an animal diagnosed with a chronic or terminal disease with 119 healthy controls blindly matched for owner age and sex and animal species.

Symptoms of stress, anxiety and depression were measured using recognised scales, and quality of life was assessed by questionnaire. Owners' demographic information was also recorded.

Results showed greater burden, stress and clinically meaningful symptoms of depression and anxiety, as well as poorer quality of life, in owners of animals with chronic or terminal disease. Higher burden was also related to poorer psychosocial functioning.

The authors outline some study limitations which could have introduced bias, but they say their findings "may help veterinarians understand and more effectively handle client distress in the context of managing the challenges of sick companion animal caregiving."

And they suggest that future research is needed to better understand risks for caregiver burden in the client, how this might be reduced, and how it impacts veterinarian wellbeing.

In a linked commentary, Katherine Goldberg calls for improved training for veterinarians around provision of long term care for serious illness. This includes tailoring treatment plans to client preferences, recognising when clients are distressed, and partnering with mental health professionals to provide support.

"This inaugural exploration of caregiver burden within a veterinary setting is the first step in assessing the impact of veterinary caregiving on clients, as well as the impact of client emotional distress on veterinarian wellbeing," writes Goldberg. "It is my hope that with continued dialogue, we will continue to build the literature in these essential areas."
