Providing care to patients with cancer can be overwhelming, and caregivers are at risk for physical and psychological distress, which can negatively impact their own health. Over the past decade, supporting caregiver well-being has gained prominence as a national health-care issue. In this article, Dr. Applebaum emphasizes the importance of extending psychosocial support for caregiver well-being and highlights the evidence base for helpful interventions, which include cognitive behavioral therapy, yoga, and meditation.
CAREGIVERS, WHO may be relatives, friends, or partners who have a significant relationship with and provide assistance (ie, physical, emotional) to patients with cancer,1 are an essential extension of the health-care team. Today’s shorter hospital stays and shift toward increased outpatient care have placed a significant burden of responsibility on caregivers, many of whom have little to no preparation for this role. Rapid advances in cancer care have improved our ability to extend lives and enhance survival, and in many cases, cancer is now a chronic rather than abruptly life-limiting illness. These trends have significantly increased the burden on caregivers and their needs have substantially intensified.

Indeed, the number of individuals currently providing care for patients with cancer is startling: recent U.S. national estimates of cancer caregivers range from 2.8 million2 to 6.1 million adult individuals,3 with such caregivers providing care on average for 32.9 hours per week. These demands come at a significant financial cost: time costs per year of informal cancer caregiving may be as high as $73,000,4 and approximately 25% of caregivers make extended employment changes to accommodate their caregiving responsibilities.5
Negative Effects of Caregiving
THIS UNCOMPENSATED care involves significant time and energy as well as requires performing tasks that are physically, emotionally, socially, and existentially demanding. Indeed, caregivers are at risk for psychological (eg, anxiety, depression, and hopelessness)6 and physical (eg, increased mortality, cardiovascular disease, poor immune functioning, and sleep difficulties)7 complications. Although some studies of caregivers reported comparable rates of depression and anxiety to those of patients for whom they provide care,8-10 others have shown rates that surpass those of patients.11

For example, rates of depression between 12% and 59% and anxiety between 30% and 50%12,13 have been reported in samples of caregivers, in comparison to those of depression between 10% and 25%14 and between 19% and 34%15 in the patient population. Additionally, between 40% and 76% of cancer caregivers reported clinically significant symptoms of insomnia,16,17 which negatively affect their mental and physical health, are frequently chronic, and may impair the normal grieving process among bereaved caregivers.18 These symptoms can increase the risk for chronic illness in caregivers, including cardiovascular disease and cancer.
Furthermore, caregiver burden has the potential to negatively impact the quality of care provided to patients and subsequently their health outcomes.19-21 For example, depressed mood and higher anxiety among caregivers have been associated with patient distress21 and increased use of aggressive and unnecessary treatments toward the end of life.22,23 As such, this chronic, untreated burden experienced by caregivers not only increases their chances of becoming the next generation of patients, but it may generally add further burden to health-care expenditures.
CAREGIVERS OF patients with cancer are therefore in great need of psychosocial support. Thankfully, the state of the science of cancer caregiver intervention research is no longer in its infancy. There is strong and growing evidence for the efficacy and effectiveness of empirically supported treatments—psychoeducation,24,25 cognitive behavioral therapy,26,27 and problem-solving therapy28,29—to address various domains of caregiver burden and unmet needs. Such interventions have been shown to improve caregivers’ skills, self-efficacy, and confidence in their role as well as to help them navigate the prolonged and often intensifying challenges experienced across the caregiving trajectory. Indeed, short-term interventions can afford caregivers the skills necessary to face the challenges of caregiving and protect them from the negative outcomes described previously.
There is also a growing body of evidence for the benefits of mind-body therapies, such as yoga and meditation, on the symptoms of depression, anxiety, insomnia, and overall health-related quality of life of caregivers.30-32 Additionally, many support programs are now capitalizing on the rapidly advancing telehealth technologies to deliver interventions to diverse groups of caregivers across the country and the world.33
First Step: Screen for Caregiver Distress
TO IDENTIFY caregivers in need and route them to appropriate supportive services, however, it is necessary first to screen for distress. For patients with cancer, distress screening has become a standard of care, but routine and comprehensive distress screening for caregivers has yet to be implemented.34 Caregiver-focused distress screening programs have the potential to improve the quality of care for all those affected by cancer.

It is also necessary for individuals on the front lines—the various medical professionals who come into contact with families in inpatient and outpatient settings—to recognize the signs of caregiver burden and understand how to route caregivers to support in their unique systems. More broadly, as health-care professionals supporting families facing cancer, we must press strongly and advocate for policies that broadly acknowledge caregiver burden as a national health-care issue as well as continue to encourage a paradigm shift from patient-centered to family-centered care. ■
