Nurses in the Lead - Nursing Leadership and Autonomy in Function Focused Care in Hospital

The goal of this prospective before-after study (observational) is to implement Function Focused Care in Hospital (FFCiH), paying specific attention to the role of nurses and how they can take the leadership and autonomy in the interprofessional collaboration regarding FFCiH. To reach this aim, the researchers defined two sub-objectives: 1\. to identify barriers and facilitators (determinants) for nursing autonomy and leadership and application FFCiH in the interprofessional collaboration on a surgical and internal medicine ward to design a tailored implementation strategy for FFCiH. 2. to evaluate the effectiveness of the implementation strategy on nursing leadership and the application of FFCiH. The investigators developed two work packages related to the two sub-objectives: identifying determinants and strategies for the successful application of FFCiH and nurse leadership, among others, by introducing nurse champions and evaluating their effect on the application of FFCiH. The primary endpoint is the level of application of FFCiH as reflected in adherence to and coverage of FFCiH in daily nursing care. The secondary endpoints are: 1) for nurses: the nurses' role development with regards to leadership and autonomy in the application of FFCiH by ward nurses and nurse champions, leadership competencies of ward nurses, and autonomy of ward nurses and 2) for patients: physical functioning and independency in mobility and ADL. Researchers will compare FFCiH with usual care to see if there are differences regarding the outcome measurements. The study population consists of nurses, physiotherapists, doctors, other member of the interprofessional team, hospitalized patients and their relatives. Intervention: FFCiH focuses on stimulating nurses to promote patients' self-reliance in daily functioning, encouraging the patients' engagement in daily activities and, helping patients to attain and maintain their highest level of function and increasing time spent in physi
