Patient’s duties are a topical but little researched area in nursing ethics. However, patient’s duties are closely connected to nursing practice in terms of autonomy, the best purpose of care and rethinking from the patient’s perspective. This article is a metasynthesis (N = 11 original articles) of patient’s duties, aimed to create a tentative model. In this article, a tentative model called ‘right-based duties of a patient’ was constructed. With its aid, a coherent structure of patient’s duties within different roles (...) and objects of a patient can be defined. In addition, the ethical basis, prerequisites, outcomes and risks of patient’s duties can be named. In conclusion, so-called right-based duties of a patient constitute the basic argument. Patient’s duties are not unambiguous for all patients, and the global perspective to duties has been challenged. However, due to both conceptual and practical reasons, rethinking of patient’s duties is needed. (shrink)
