"De huisarts heeft me meteen naar het ziekenhuis gestuurd."
Translation:The general practitioner sent me to the hospital immediately.
If I understand "huisarts" correctly, then "primary care physician" or "primary care doctor" (as those terms are used in the US) should be considered correct. A primary care doctor is your first stop when something is wrong with your health, and he may refer you to a specialist, depending on the diagnosis (or need for further evaluation). Is that what een huisarts does?
