Palliative care considerations in frail older adults

Frailty is a common geriatric syndrome characterized by a decline in physical and cognitive abilities and an increased vulnerability to stressors such as illnesses and injuries. As the global population is aging, the prevalence of frailty is growing. Frail older adults are at substantial risk of developing mobility and self-care difficulties, hospitalization, and death. Frailty is also associated with a high symptom burden and psychosocial stress, including malnutrition, pain, fatigue, weakness, cognitive loss, depression, falls, and sleep disorders, among others. The role of palliative care is gaining attention in medical literature because frailty is associated with increased morbidity and mortality. While there are no specific guidelines yet for when palliative care should be consulted in older patients with frailty, it has been proposed that palliative care should be considered in frail patients with continued functional decline, increased healthcare utilization, and uncontrolled symptoms. Palliative care can aid in communication with patients and families, establishing goals of care and treatment preferences, improving pain and symptom control, addressing psychosocial and spiritual needs, advance care planning, caregiver needs, and end-of-life care. Once frailty is identified, a comprehensive evaluation of the patient's physical, psychosocial, and spiritual aspects of care is essential for establishing a patient-centered treatment plan. This paper aims to guide clinicians in providing patient-centered care for older adults with frailty in the outpatient setting. Through a comprehensive literature review, we describe the leading models of frailty, frailty screening tools used in the clinical setting, and the assessment and management of palliative care needs in frail patients. We also describe emerging models of care focusing on palliative care for older adults with frailty and discuss issues related to access to palliative care for this population.
