Of 1,476 nonduplicate citations, 17 matched the inclusion criteria.ResultsFindings revealed that healthcare professionals’ ethical competence is a limited but topical research area. The focus areas of the studies were conceptualization, measuring, and realization of the ethical competence. The studies provided varying definitions and constructions for ethical competence and a few instruments to measure ethical competence were identified.
