The number of frail older adults in Canada is expected to rise from 1.1 million to more than 2 million by 2035.(1) Frailty is difficult to define, but most definitions consider it in terms of vulnerability,(2; 3) which can relate to physical, emotional and social factors.(4; 5) In relation to physical factors, this often means having a general lack of strength; being more vulnerable to disease (for example, having one or more chronic conditions) or disability (for example, a lack of mobility); and deteriorating in health more quickly as a result of diseases and disability (including cognitive deficits and/or dementia).(1) Emotional and social factors can relate to many things that lead to vulnerability (and eventually greater risk of functional impairments and diseases), including lack of emotional and social support and social isolation.(3) Frail older adults are at greater risk for chronic illnesses (6; 7) and disabilities which make it difficult to perform basic daily activities.(6; 8)
Frail older adults have significant care needs, and often rely heavily on caregivers to support them.(9) A caregiver may be an intimate partner, a family member, a friend, or a volunteer who may also themselves be frail or at risk of becoming frail. The roles of caregivers of frail older adults can be significant and may take various forms, such as:(10)
- providing emotional support;
- transporting or accompanying patients to medical appointments;
- reporting or managing side effects;
- giving medicines;
- keeping track of interventions (for example, for nutrition and exercise), medicines, test results and papers;
- providing physical care (for example, feeding, dressing and bathing);
- coordinating care (including navigating the system and advocating on behalf of their loved ones);
- keeping family and friends informed; and
- making legal and financial arrangements.
Despite their crucial role, support for caregivers is often lacking or inconsistently available.(11; 12; 13) This lack of support can have a negative impact on the physical and mental health of caregivers, on their personal and professional lives, and on the quality of care that they provide.(14) As reported during a forum with caregiver groups: “Failure to recognize, acknowledge and support family caregivers heightens their risk of becoming ‘collateral casualties’ of the illness, compromises their health, reduces the efficacy of the help they can provide to their relatives, and increases costs to the health and social service systems.”(14)
What the research tells us
There is a growing body of research evidence examining interventions to support caregivers in their efforts to prevent, delay the onset of, and manage the burden of frailty.
Addressing the economic security of caregivers
While we found no systematic review on employment arrangements or income supports for caregivers, some policy proposals have recommended that there should be supports for employed caregivers to continue to work, and that assistance should be provided to those that are most in need.(11)
Engaging caregivers in decision-making about needed care, and about how care and support is organized
Other interventions aim to engage caregivers in decision-making about how care and support is organized to ensure it is appropriate for their needs. Engaging caregivers was found to: create a more rewarding experience for healthcare staff; increase access for those with disabilities; simplify appointments; result in more efficient transportation between services; and increase organizational attitudes that support caregiver and patient involvement.(15)
Providing materials to help caregivers make decisions (often called decision aids) were found to increase the understanding of care options, risks and outcomes, improve involvement, and support professionals in counseling and sharing information with patients and caregivers.(16; 17; 18; 19)
Caregivers could also be provided with training to better prepare them to participate and engage in policy and care-planning discussion, and to determine what they see as appropriate supports for their specific situations.(20; 21)
Providing education and supports to reduce caregiver burden and to help them cope and build resilience
There is mixed evidence about whether education and training reduced caregiver burden.(22; 23; 24; 25) However, training in coping strategies was found to improve the mental well-being of caregivers.(26) In addition, providing assistance and emotional support to caregivers was found to improve their mental and physical health. It was also found to improve their engagement with social activities and reduce depression.(27) When education and training about the health needs of the person they are caring for was provided alongside assistance and emotional support, caregivers were found to have a reduced level of burden and stress.(28; 29) However, not enough evidence could be found to determine whether respite care (meaning, the services that provide a ‘break’ for caregivers) reduced caregiver burden.(30)
Take care of yourself too!
It can be particularly challenging to provide care to a loved one. But don’t become a collateral casualty. Take care of yourself, and seek help.
