In the last years, popular understandings of the importance of the primary care physician (also known as the General Practitioner, or family doctor) have changed, at times in high demand and importance, at others thought of as obsolete. Nowadays, popular consciousness holds that a GP is crucial to providing an overview of the complex jungle of specialist, sub-specialist, and sub-, sub- specialists, treatments and therapies may be mutually contradictory. Another advantage is that the GP knows his or her patients intimately. Ms. Smith might complain about back pain, but the GP knows she has a herniated disc. By contrast, a specialist might start a rabbit hole of investigations that don't necessarily make sense without an adequate starting point.
