Clinical expertise, as described by Patricia Benner in her classic work "From Novice to Expert: Excellence and Power in Clinical Nursing Practice," consists of five distinct components:
Skill Acquisition: This is the ability to perform the technical aspects of nursing practice. It includes being able to remember and apply nursing theory, principles and strategies in order to provide optimal care.
Pattern Recognition: This involves the ability to recognize and interpret subtle cues about patient/family behavior and responses, diagnose and intervene appropriately.
Sensitivity to Context: This means being aware and flexible when dealing with patient/family situations. Nurses should be able to respond to changes and recognize hidden meanings, focusing on the needs of the patient or family instead of a predetermined plan.
Clinical Judgment and Ethical Action: This is the ability to critically evaluate, decision-make, and provide optimal care. It requires professionals to use expert clinical reasoning, and to be ethically responsible in all actions taken.
Reflection and Refinement: Clinical expertise also requires self-reflection and the willingness to learn from one's mistakes and experiences in order to continually refine one's performance.
In conclusion, clinical expertise according to Benner includes skill acquisition, pattern recognition, sensitivity to context, clinical judgment and ethical action, and self-reflection and refinement. Nurses should strive to develop each of these components in order to be the best health care providers they can be.
