Clinical Nurse Specialists (CNS)

A Clinical Nurse Specialist (CNS) is an advanced practice registered nurse (APRN) who has completed additional education and training in a specific area of nursing practice. They are experts in clinical practice, education, research, and leadership.

Importance of the CNS Role in modern healthcare

The Clinical Nurse Specialist (CNS) role is becoming increasingly important nowadays in modern healthcare because of the growing complexity of healthcare delivery, the need for specialised expertise to address some of the complex health issues, and the recognition of the importance of evidence-based practice. 

CNSs are vital in improving healthcare quality and patient outcomes, reducing healthcare costs, and advancing the nursing profession.

Their role extends into other areas, such as healthcare management and research. Clinical nurse specialists can work in hospitals, clinics, nursing homes, and other settings such as public health offices. According to the 2020 National Association for Clinical Nurse Specialists census, nearly half of CNSs usually work with adults or older adults. 

CNSs across all specialities spend most of their time precepting students, assisting with projects and research, providing direct patient care, and educating other staff members. A CNS works evenings, nights, weekends, and holidays in hospitals and other institutions that are always open.
