RESUMO
New graduate clinical nurse specialists (CNSs) face many challenges when starting their new role. To address this, a CNS fellowship program was developed to mentor new CNSs during their first year of practice. This CNS fellowship program would provide opportunities to increase skills related to each of the CNS spheres of influence, including nursing practice, patient care, and systems and organization. Experienced CNSs mentored CNS fellows and identified learning opportunities. The fellows completed an online self-assessment based on the National Association of Clinical Nurse Specialists CNS Competency Checklist during week one of orientation and again at months 3, 6, 9, and 12. The CNS fellows completed and presented three projects designed to explore the spheres of the CNS role, along with a formal onboarding. The results of the fellowship depicted significant competency development within all three CNS spheres at program completion. The CNS fellowship program provided structure and guidance to the newly graduated CNSs and clearly transitioned staff nurses to advanced practice nurses. The fellowship has demonstrated a positive effect on both the new CNSs and the organization in which it was developed.
