Physicians are doctors who have completed further training in a medical specialty to diagnose and manage complex medical problems. A physician typically works in a hospital, and their central duty is to carry out the investigations and procedures necessary to establish a diagnosis, and then to give advice and provide treatment where appropriate.
Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.
