Scope of Practice
Clinical Nurse Specialists acquire expertise and practise in a defined specialty area in which they have acquired certification following their master’s degree or doctorate. The scope of their work has established parameters related to a specific population, such as children or adults, a health speciality, such as diabetes or gynaecology, or a setting, such as the critical care unit or emergency room. Their expertise enables them to deliver patient care and serve as consultants and coaches to other healthcare professionals within their specialty.
Some Types of Clinical Nurse Specialists
Working in their specialty area, Clinical Nurse Specialists deliver patient care, provide education and support to patients and their caregivers, and train other healthcare professionals.
Adult Health CNS: Working typically in multispecialty hospitals, clinics, nursing homes and long-term care facilities, they look after the medical needs of adult patients with diverse acute or chronic illnesses, such as coronary disease, diabetes and respiratory disorders.
Paediatric CNS: Working typically in paediatric hospitals or clinics, multispecialty healthcare facilities and schools, they focus on caring for children, ranging from newborns to adolescents, with various health conditions.
Gerontological CNS: Working typically in long-term care facilities, nursing homes, assisted living facilities and hospitals, they tend to the medical needs and care of older adults with age-related conditions, such as dementia, and chronic health issues, including heart disease, diabetes and arthritis.
Oncology CNS: Working typically in hospitals, clinics and cancer centres, they focus on the care of cancer patients with cancer, which includes diagnosis, treatment and symptom management.
Psychiatric-Mental Health CNS: Working typically in psychiatric hospitals, community mental health centres and private practices, they care for patients with mental health issues, including depression and schizophrenia.
Neonatal CNS: Working typically in neonatal intensive care units (NICUs), birthing centres, maternity clinics and multispeciality hospitals, they look after newborn infants, including premature babies or those with complex medical issues.
Women's Health CNS: Working typically in obstetrics and gynaecology clinics, women's health centres and multispecialty hospitals, they focus on women’s health across the lifespan.
Critical Care CNS: Working typically in intensive care units (ICUs), emergency departments, and trauma centres, they deliver medical care to critically ill patients.
Advanced Practice Registered Nurse (APRN)
An Advanced Practice Registered Nurse (APRN) holds a master’s degree in nursing or a doctorate and has passed the relevant national certification exam. The four types of ARPNs are the certified registered nurse anaesthetist (CRNA), certified clinical nurse specialist (CNS), certified nurse-midwife (CNM) and certified nurse practitioner (CNP).
The Three Spheres of Influence
Patient Sphere: Direct patient care in diverse settings falls within this sphere. Clinical Nurse Specialists typically collaborate with other nurses, consulting with them and other healthcare professionals to improve and implement plans of care based on evidence-based recommendations within their speciality area.
Nurses/Nursing Sphere: Influencing patient outcomes by advocating and incorporating evidence-based practices and changes into nursing operations fall within this sphere. CNSs aim to apply cutting-edge scientific research to daily clinical practice. They do so by engaging with nursing staff within their specialty area to discuss their work and derive potential research questions while, in turn, coaching them to adopt the latest scientifically proven practices rather than just those that are in customary use.
System/Organisational Sphere: Using their expertise to influence the future of the overall healthcare system falls within this sphere. Recognising the growing complexity and costs of healthcare, CNSs may conduct cost-benefit analyses of upcoming medical products, procedures and programs and also evaluate preventive protocols. Their independent but evidence-based findings can be integrated into medical policy.
Related Alternative Careers
Registered nurses (RNs) typically require only a bachelor's degree to work, unlike Clinical Nurse Specialists. However, like CNSs, they may specialise in a medical field, such as neonatal nursing and cardiovascular nursing. Similar to CNSs, physician assistants must hold a master's degree. However, they carry out many of the duties of physicians working under their supervision.
The Role of Clinical Nurse Specialists Worldwide
Equipped with advanced and specialised knowledge, skills, aptitude and qualifications, Clinical Nurse Specialists in the US carry out their duties in diverse healthcare settings. However, the role has varying job descriptions and titles worldwide, such as Clinical Nurse Consultant, or may not even possess a protected title. What may be common to the role in its various forms is the need to acquire postbaccalaureate qualifications, which likely lead to certification, since job responsibilities include delivering patient care to vulnerable patients and those with complex conditions, educating and mentoring nurses and other healthcare professionals, and bringing about innovation and evidence-based improvements in healthcare systems to achieve optimal outcomes for patients/populations.
There is a global need for what a CNS does, but formally implementing the role across countries and settings requires supporting relevant education and regulation. The challenges in formalising the role include securing title protection, defining the scope of practice and core competencies, establishing educational standards and the requisite theoretical curriculum, practicum, certification and regulation. For global recognition of their role and success in delivering their services and to promote wellness universally, CNSs must be accessible to the public, and their role must be integrated into healthcare systems and patient care.
Current Scenario
The employment outlook of a particular profession may be impacted by diverse factors, such as the time of year (for seasonal jobs), location, employment turnover (when people leave current jobs), occupational growth (when new roles are created), size of the occupation, and industry-specific trends and events that affect overall employment.
While data specific to Clinical Nurse Specialists may not be available, the employment of Registered Nurses and other categories of Advanced Practice Registered Nurses (nurse anaesthetists, nurse midwives and nurse practitioners with similar education and training to CNSs) is expected to grow over the next few years. Qualified, compassionate and diligent nurses play critical roles in caring for patients, assisting physicians and other healthcare professionals, and keeping healthcare systems and institutions running smoothly.
The pandemic created a spurt in the demand for nurses. In addition, the ageing generation of baby boomers that lives longer thanks to medical advances but deals with reduced health and mobility also needs nurses. With a more precise definition and better regulation of their qualifications and scope of practice, Clinical Nurse Specialists may play increasingly pivotal roles across countries and medical facilities.
Potential Pros & Cons of Freelancing vs Full-Time Employment
Freelancing Clinical Nurse Specialists have more flexible work schedules and locations. They fully own the business and can select their projects and clients. However, they experience inconsistent work and cash flow, which means more responsibility, effort and risk.
On the other hand, full-time Clinical Nurse Specialists have company-sponsored health benefits, insurance, and retirement plans. They have job security with a fixed, reliable source of income and guidance from their bosses. Yet, they may experience boredom due to a lack of flexibility, ownership, and variety.
When deciding between freelancing or being a full-time employee, consider the pros and cons to see what works best for you.
