Clinical Nurse Specialist (CNS)

Overview

What Is a Clinical Nurse Specialist?

A Clinical Nurse Specialist (CNS) is an Advanced Practice Registered Nurse (APRN) who focuses on improving patient outcomes and nursing practices within a specific area of expertise. This specialization can be based on a population (such as pediatrics, geriatrics, women's health), a setting (such as critical care, emergency room), a disease or medical subspecialty (such as diabetes, oncology), a type of care (such as psychiatric, rehabilitation), or a type of health problem (such as pain, wounds, stress).

Clinical Nurse Specialists are leaders in healthcare, utilizing their advanced clinical skills and in-depth knowledge to assess, diagnose, and treat patient illnesses, while also implementing evidence-based practices. They serve as mentors to nursing staff, help to design and improve healthcare delivery systems, and advocate for policies that enhance patient care. The Clinical Nurse Specialist role is pivotal in bridging the gap between administration and bedside care, ensuring that patient care is both efficient and of the highest quality.
