Managing the transitional care needs of young adults with a complex chronic illness such as cystic fibrosis (CF) as they move from a child-orientated to adult setting has been reported in the literature as challenging and stressful, and may impart additional risks to the young person's health. However, in the Republic of Ireland, which has the highest incidence of CF in the world, the current services provided for children during this transitional period are still reported as underdeveloped. The aim of the author's research was to explore and understand the experience of young people before and after their transitional care, and the factors that both contribute to and hinder that experience. A qualitative approach guided by phenomenological tradition, and using in-depth interviews. The findings suggest that there are a range of needs required for patients during this transitional period, including the need for information, interventions that decrease the negative feelings associated with transition (e.g. distress, anxiety, uncertainty), structured service, and an approach to care that focuses on young adults. The author concludes that health professionals in the clinical setting who have responsibility for young adults in transitional care should focus on these needs to provide a more relevant and effective transition service.
