Background The growing number of older people worldwide poses challenges for health policy, particularly in the Global North, where policymakers increasingly expect seniors to live and receive care at home. However, healthcare professionals, particularly in home-based care, face dilemmas between adhering to care ideals and meeting external demands. Although they strive to uphold ethical care standards, they must deal with patients’ needs, cooperation with colleagues and management guidelines. Home-based care is an essential part of healthcare services in Norway, but staff (...) struggle with high patient numbers and time management. This article focuses on how staff deal with ethical challenges related to contextual and organisational constraints. Methods An ethnographic fieldwork in three municipalities in South-East Norway. The first author conducted three to four months of participant observation in each municipality. In addition, she conducted in-depth interviews with key informants in two municipalities and a focus group interview with seven home-based care workers in one municipality. The data was analysed by using a reflexive thematic analysis. Results Staff in home-based care are frequently more loyal to the patient than to the system and to their own needs. To provide good care, all informants disregarded the patient’s formal decision, i.e. they provided more care than the formalised decision stipulated. To prioritise beneficence to patients, informants also disregarded some of the rules applicable in home-based care. In addition, staff accepted risks to their own safety and health to provide care in the patient’s home. Conclusion The loyalty of home-based care staff to their patients can go beyond their loyalty to the rules of the system and even their own safety. This commitment might be attributed to a sense of doing meaningful work, to providing relationship-based and individualised care, and to strong moral courage. However, the staff’s emphasis on flexibility and individualised care also brings challenges related to unclear boundaries related to patient care. (shrink)
