I'm not a doctor, but I play one on TV.
What I mean is, I have zero personal experience with studying or teaching medicine. But I've read books about people going through medical training. So my answer will only be as good as those books (and my ability to imagine that world).
- How do good students distinguish themselves?
Judging by the context you gave, of reading a professor's CV, I think you're asking how one can tell who the rock stars are.
In academia: the length and the quality of the publications list, getting on the cover of an important journal, winning a prize, getting a prestigious fellowship, being an invited speaker, etc.
In medicine: here I'm less sure of my answer, but I think the items I mentioned for academia would apply as well. Also, when I hear one mental health professional speak of another one's credentials, they seem to know which are the really good training programs, so if someone has listed one of those on their CV, then that's a feather in their cap.
Perhaps you are asking, how do selection committees figure out which are the strongest candidates for a position. I imagine the reputation of the training program, and the recommendation letters, must be extremely important. Blue-blue-blue's answer gives an insider view of what a supervisor thinks about when preparing to give a reference (compassion, creativity, problem solving, communication, collaboration).
From my reading (which I will say once more, may have given me a totally wrong impression), here is what one has to do to be a successful medical student:
learn to do practical things like drawing blood, not necessarily with the benefit of step by step training in how to do it efficiently (in other words, this part of the job can be pretty sink or swim)
be respectful of nurses
respect the medical hierarchy
stay on top of an enormous amount of reading, so as to be able to answer impromptu verbal quizzes in front of fellow students, and also so as to be able to care for patients and do the creative problem solving mentioned by blue-blue
work incredibly long shifts, catching naps as catch can
navigate electronic records comfortably
be efficient
manage one's anxiety about appearing stupid, or about making a mistake
learn enormous amounts of material and figure out a way to catalog it all in one's brain
- I saw what seems to be labeled as "competitiveness" of various programs, with dermatology and plastic surgery being highly competitive and family practice and psychiatry being the least.
I think what you saw was a rating system indicating the relative ratios of #slots divided by #applicants. If that ratio is much higher in one specialty than another, then it is called "highly competitive."
If you are wondering how a student should use this information when choosing a specialty, my personal opinion is that one should be primarily guided by one's natural affinity for an area of medicine. (I can tell you that I was not very encouraged when I was in the hospital with a serious fracture, and the attending specialist who was overseeing my care, and checking on me from time to time, heard that my spouse is a physicist, and confided in me, "I always wanted to study physics, but my father said the only way he'd pay for my college was if I studied medicine.")
- So how can you tell how good a student is in medical school if there is no GPA and if getting into a specialty also don't indicate that?
See above. Also, when I was choosing a pediatrician for my first child, here are the qualities I valued in the one I chose:
She was able to connect with the child and with me
She listened to my point of view
She explained things clearly
She sometimes mentioned recent research results as they related to the issue the child was having, and sometimes on a subsequent visit I was able to see that she had done some reading in the interim (that really distinguished her from most doctors I had seen; maybe they all do that, but just don't talk about it....)
She gave us useful advice (sorry to have put that at the end, it's of course just as important as the other things)
And here are the reason I switched to someone different after some time:
We were having trouble getting child #2 diagnosed; I found an article I thought could give us some clues (it turned out, in fact, to provide the key to what was wrong), but when I mailed it to her and asked her to read it, and made an appointment for one month later, when we got there, she still hadn't read it.
She refused to use email or a patient portal or fax to communicate with me. It was very frustrating always to have to go through a semi-literate receptionist.
The current doctor of child #2 has some modern tech-related qualities that I really appreciate:
She checks frequently for messages that come in from patients through the receptionist and the patient portal.
She responds promptly through the patient portal, writes helpful letters explaining to the school what the child needs, and gets the letters to me directly through the patient portal. That gives me a chance to preview the letter and let her know if there's something the school is liable to misunderstand -- before the letter gets sent to the school.
