APRN Roles and Practice
Introduction
Advanced practice registered nurses (APRNs) play a vital role in expanding access to healthcare services. The four APRN rolesβnurse practitioner (NP), clinical nurse specialist (CNS), certified registered nurse anesthetist (CRNA), and certified nurse-midwife (CNM)βeach have distinct histories and responsibilities that collectively enhance healthcare delivery. This paper will discuss the historical development of one APRN role and briefly describe the general responsibilities of the four roles.
Nurse Practitioner Role
One of the earliest APRN roles to emerge was the nurse practitioner (NP) in the 1960s. At this time, there was a shortage of primary care physicians, especially in rural and underserved areas (AANP, 2022). In response, NPs were educated to provide services traditionally delivered by physicians to expand access to care. Specifically, NPs received advanced education enabling them to examine, diagnose, and treat patients across settings (NCSBN, 2022). Over time, the NP role has continued to evolve and take on more responsibilities. Today, NPs practice autonomously and play a critical role in meeting the growing demand for primary, acute, and specialty healthcare services (NCSBN, 2022).
APRN Role Responsibilities
In addition to the NP role discussed above, the three other APRN roles each fulfill important responsibilities in healthcare. Clinical nurse specialists (CNSs) provide direct patient care as well as broader roles in research, administration, and education across various settings (NCSBN, 2022). Certified registered nurse anesthetists (CRNAs) administer anesthesia, perform pain management, and provide pre- and post-anesthesia care autonomously or under physician supervision (NCSBN, 2022). Finally, certified nurse-midwives (CNMs) provide primary care related to women’s reproductive health, pregnancy, childbirth, and the postpartum period in a variety of settings (NCSBN, 2022).
Conclusion
In summary, APRNs have a long history of expanding access to healthcare through their diverse and specialized roles. Looking to the future, APRNs will continue developing their practices based on evolving population needs and research evidence. National organizations establish guidelines to ensure high-quality, cost-effective APRN practice (NCSBN, 2022; AANP, 2022). Overall, APRNs are integral members of the healthcare workforce who enhance patient outcomes through their distinct and collaborative roles.
