Clinical medicine

Clinical medicine is the field of medicine that primarily focuses on the direct care of patients, involving the study, diagnosis, treatment, and prevention of diseases. It encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness in patient populations.

Overview

Practitioners of clinical medicine, known as clinicians, use their knowledge of the human body to evaluate and treat patients effectively. This field is grounded in direct observation of patients and their symptoms, as well as the use of tests and imaging to develop an understanding of their health conditions.

The Practice of Clinical Medicine

Clinical practice involves a variety of methods to diagnose, treat, and prevent various diseases or disorders. This may include:

• Patient history-taking
• Physical examination
• Laboratory analysis and imaging
• Development of a management plan
• Prescription of therapy
• Follow-up and long-term management
