RESUMEN
AIMS AND OBJECTIVES: This paper aims to inform nursing and other healthcare disciplines by clearly defining patient competence and the skills required to improve self-care behaviours. BACKGROUND: Competence has been defined in education and leadership. However, competence in persons with chronic disease has not been expanded upon since one publication in 1983. Patient competence needs to be developed and defined so that healthcare disciplines can understand the attributes necessary for a patient to be deemed competent to promote self-care behaviours. DESIGN: A concept derivation. METHODS: Walker and Avant's approach to concept derivation was used to identify a base concept (competence) that is well-defined in another field, define the concepts associated with the parent field, and transpose that definition to a new field to formulate a redefined concept. PsycINFO, Scopus, Web of Science and Medline were searched, and 21 articles were included. RESULTS: Patient competence is defined as the ability of a person with a chronic illness to reach skill mastery, achieve knowledge, maintain a positive attitude and develop trust in themselves and in healthcare providers that will facilitate active engagement to improve self-care behaviours. CONCLUSIONS: Defining patient competence is important in assisting nurses and other healthcare providers in understanding the attributes needed to deem a patient competent, especially those living with chronic illnesses requiring lifelong self-care behaviours. More research is needed to aid in the designing of a precise instrument for measuring this phenomenon. RELEVANCE TO CLINICAL PRACTICE: Concept derivation of patient competence provides a framework for nurses and other members of the healthcare profession to understand the attributes needed to determine patient competence.
