Background: Advanced Practice Nurse (APN) roles in Switzerland include Clinical Nurse Specialist (CNS), Nurse Practitioner (NP) and blended roles. The variety contributes to unclear profiles and scope of practice. Aim: To describe a) the performance of APN tasks according to Hamric's competencies, b) job satisfaction, and c) barriers and facilitators to role performance. Methods: Nationwide cross-sectional survey among clinically working APNs. Inclusion criteria: academic degree, role with advanced nursing competency. Analysis of quantitative and qualitative data using inferential statistics and content analysis. Results: Of the 222 APNs, 49% (n = 108) described themselves as CNSs, 37% (n = 81) as working in a blended role, and 15% (n = 33) as NP. APNs provided the greatest proportion of their tasks in the competency direct clinical practice and the least in ethical decision-making. Group comparisons between roles revealed significant differences in the competencies: direct clinical practice, guidance and coaching, leadership, and evidence-based practice. Job satisfaction was high (76%, n = 165), most often described by the category work content/role (e.g., defined scope of practice). The most frequent barrier to role performance was the category scope of practice (e.g., unclear responsibilities); the most frequent facilitator was the category professional recognition (e.g., respect). Conclusion: The study highlights current APN scope of practice and can support the advancement of the role through clinical practice, educational institutions, and research.
