Respuesta :

Only one-third are specialists in primary care among physicians in the United States who spend the majority of their time in direct patient care. Primary care physicians comprise geriatricians, the general internists, family physicians, the general pediatricians and general practitioners. 

Answer:

Only 1/3 of US doctors are specialists and subspecialists.

Explanation:

An expert doctor is one who works with a specific field of medicine (such as an endocrinologist who deals only with hormonal issues, for example). A subspecialist doctor is another doctor who specializes in some organ or, what is often occurring, some specific disease.

This type of professional requires a long time of study and a great economic expense with the academic specialization, therefore, there are fewer specialist doctors and subspecialists than genealogical doctors, as general practitioners, who although they study a lot, can practice the profession in a shorter time period. It is estimated that only 1/3 of doctors in the US are specialists and subspecialists.
