Aims and objectivesOral care is an integrated part of everyday life. Within nursing, barriers related to providing oral care often lead to unmet caring needs. Poor oral care is associated with a risk of respiratory and cardiovascular complications during hospitalisation. Knowledge on patients' perspectives of maintaining or receiving oral care during admissions are limited. Following the Fundamentals of Care (FOC) framework, this study uses a person‐centred approach to explore patients' perceptions and experiences of receiving or performing oral care, including the nursing staff's clinical practices.Methodological design and justificationA focussed ethnographic approach was used to explore patients' perspectives and clinical practices during acute admissions in an Orthopaedic Department.Ethics issues and approvalThe local Data Protection Agency and the Ethics Committee approved the study.Research methods, results and conclusionsData were collected in an Orthopaedic ward at a Copenhagen University hospital, Hvidovre, and consisted of 14 days of field observations of clinical practices and 15 patient interviews. Data were analysed inductively using qualitative content analysis. Two themes were identified. The first, ‘The purpose of oral care is defined by the eye of the beholder’, describes the social implications for the patients and how patients reject the assumption of oral care being a transgressive act. The second, ‘The unspoken need’, focus on the lack of dialogue, including the limited provision of oral care and how the nursing staff assesses patients' ability to perform oral care (in)dependently without including the patients.ConclusionOral care is related to the patient's psychological and physical well‐being and affects social appearance. When oral care is provided respectfully, patients do not experience oral care as a transgressive act. Nursing staff's self‐assessments of the patients' (in)dependency to perform oral care risk leading to incorrect care. Developing and implementing interventions applicable to the clinical practice is needed.
