The first three editions provided content necessary for educating students for success in CNL programs and achievement of goals as they transitioned into practice. The fourth edition will expand on the previous editions and show a vision for CNLs to manage care and lead improvement teams beyond the microsystem. It will highlight the unique attributes CNLs bring to community-based population health with the integration of concepts related to social determinants of health, population health, and global impact. It will also expand on collection, analysis, and dissemination of information and how big data will continuous influence CNL effectiveness and role sustainability in a digital society. As self-care and wellness have become central themes in today's society, this edition captures different ways CNLs will have measurable impacts on the wellbeing of patients, families, and the teams they lead. As the American Association of Colleges of Nursing leads efforts to transition the baccalaureate, masters, and doctoral essentials to a competency-based structure, the fourth edition will include how this will impact CNL education"--
