"Clinician vs physician" and "attending" 07:40 Nov 19, 2018
So I will break this up into two parts.
Physicians are often clinicians but not all clinicians are physicians. A clinician is simply someone who diagnoses patients and orders treatments in a healthcare setting. In the U.S. healthcare system, this could be a nurse practitioner (NP) or physician assistant (PA) (both called "mid-level providers") in addition to a physician. A physician is a doctor, however, anyone can call themselves a doctor; "physician" is a legally protected term in many states. "Provider" is another word that people use to identify anyone who can diagnose and make treatment plans at least semi-autonomously (NPs, PAs, MD/DO).
"Attending" is also a nuanced term. I am glad you provided the context, because attending physician very often means the supervising physician at a teaching hospital; they supervise trainees AND the patient's care. You will often hear the phrase "let me check with my attending first" from resident physicians! Resident physicians have completed medical school but are in supervised speciality training.
In the case of your translation however, "clínico tratante" o "clínico responsable" seems suitable. I hope this helps everyone! |
