Background Research in surgical care has highlighted the need to improve the delivery of person-centered fundamental care. The inCHARGE programme—Innovations to Utilise Nurses’ Competence and Achieve Person-Centered Care: Fundamentals of Care Goes into Practice—is a research program aimed at identifying and co-creating interventions to promote person-centered fundamental care in a surgical department. Aim The aim is to describe the processes within the programme and how its outcomes inform clinical practice and enhance the delivery of person-centered fundamental care to patients. Methods The program adopts an action research approach. Since 2022, the research team has collaborated with nursing staff and leaders across three surgical wards in a university hospital in Sweden, to design actions and interventions that influence the direction of nursing practice. Initially, nursing staff participated in interactive workshops that included education on person-centered fundamental care, professional role responsibility, and leadership. Data collection includes measures of missed nursing care, person-centered climate, and patient preferences for participation, alongside patient interviews, written reflections, and focus groups. The Fundamentals of Care framework serves as the overarching theoretical framework. Results Findings show multifaceted factors that enable or hinder nursing staff in delivering person-centered fundamental care. These include the need for a culture of daily mentorship to ensure adherence to person-centered routines and to embed person-centered care into everyday thinking and practice. Results from the programme’s sub-studies have guided the development and (re-)implementation of person-centered routines across the three wards. The presentation will provide a snapshot of these results and outline the collaborative process. Conclusion To support the delivery of person-centered fundamental care and facilitate changes in clinical practice, this action research programme offers a promising design and content. The results can be used to demonstrate the need for change and to navigate the complex implementation of person-centered fundamental care in clinical settings.
