Q: How is a Clinical Nurse Leader different from a Clinical Nurse Specialist or other advanced practice nurse?
The CNL is not prepared as an advanced practice nurse (APN) as the APN is currently defined. The CNL is an advanced generalist in contrast with the specialized focus of the practice by clinical nurse specialists (CNS) and nurse practitioners. Advanced practice nurses are prepared with specialist education in a defined area of practice. The CNL and APN roles complement one another. For example, the CNL may call on the CNS to provide consultation when a specialist area of concern arises (i.e. when a patient does not respond to nursing care or therapeutics as expected). AACN, in consultation with a leading group of CNSs, has developed a document, The CNL-CNS Roles: Similarities, Differences and Complementarities. http://www.aacn.nche.edu/CNL/pdf/CNSComparisonTable.pdf
