Clinical nurse specialists in California: who claims the title?

State nursing practice acts granting legal authority to advanced practice nurses vary widely, with many states not recognizing clinical nurse specialists (CNSs). This survey identified characteristics of registered nurses claiming the CNS title in California. A literature-based survey tool was designed, piloted, and distributed to 209,846 nurses in California, with instructions to return the survey if the recipient self-identified as a CNS. Among the 1061 respondents, 65% were prepared with a Master's in Nursing. Most CNSs practiced in hospitals, and patients were the most frequently listed clients. CNSs overwhelmingly identified their primary role as clinical expert. Major barriers to practice included lack of public recognition and legal recognition in nursing practice acts. Significant differences were found in most characteristics between graduate-prepared and nongraduate-prepared CNSs. Variability in practice and educational preparation is not only potentially confusing to other healthcare providers and the public, but it may not serve the best interests of CNS clients.
