Introduction For the last few decades, Ireland had been a sweet demographic spot with a high birth rate in the 1980s, implying that the country had a large cohort of working-age people in the population. However, Ireland is now getting old, with the aged people above 65 years increasing by 19.1% by 2016 (Statista, n.d.). There is a need for healthcare systems to strengthen their systems to care for vulnerable older adults. The role of caring for older people means fulfilling their special unique requirements and needs that come with old age. It includes a series of duties and responsibilities such as assisting with personal care, mobility assistance, basic food preparation, personal supervision, general healthcare, emotional support, health monitoring, and backup care services. Various disciplines are involved in the care of older adults including, general practitioners, nurses, specialized geriatric services, dieticians, and primary care psychologists (Donelan et al., 2019, p. 943). However, nurses have the most significant roles in caring for older people, including treating the aged’ complex mental and physical health needs by helping them cope with changes in their mental and physical abilities as they age. This study aims to establish the roles and duties of each discipline involved in healthcare and the support that needs to be put on frail older people. Roles and duty of care of each discipline involved in caring for frail older persons Each of the above disciplines engaged in caring for the aged has their specific duties, which they have to accomplish towards providing care for aged individuals. Inter-disciplinary care teams help provide the aged patient with a greater depth of care which ensures that all the needs of the older adults, including emotional, social, and physical, are catered for. The general practitioners are involved in assessing, diagnosing, treating, and managing illness for aged people (Ben-Harush et al., 2016, p. 42). They are mostly involved in screening illness for aged people and act as patient advocates to ensure that older patients get high-quality health and social care. Registered nurses also have a role in caring for the aged, which includes supporting aging patients to live in a setting of their choice, having their preferences, and ensuring a social connection. Nurses identify initiatives that support healthy aging and involve the aged in them, such as meeting, organizing for walks in the park, and meeting other older people (Ben-Harush et al., 2016, p. 42). Nurses provide functional physical and mental healthcare for older patients and sometimes palliative care or end-of-life care for older adults in Ireland. Specialized geriatric nurses help in diagnosing, treating, and rehabilitating frail older people in Ireland. Geriatric nurses provide practical care to older adults to help them recover from illness or injury. They are also trained to provide preventive care, administer medication, and assist older adults in pain management (Donelan et al., 2019, p. 945). Geriatric nurses are authorized to conduct random check-ups and provide rehabilitation of elder individuals in healthcare facilities. Dieticians also have a role in caring for the aged because they provide expert nutrition and dietary a
