No, you don’t.
In medicine, certainty is a very dangerous thing. It’s ok to be certain about things like the price of gas or your dislike of prunes (couldn’t blame you).
Certainty in medicine is quite another.
And, although politically incorrect to say it, I’m finding a frustrating amount of unjustified certainty among the ranks of the “mini-docs”. By mini-doctors, I mean all the permutations of lesser-trained white coat-donners. The PA’s, ARNP’s, Dr. RN’s, LPN’s, etc.

Hello. I'm not-quite-a-doc. I know EXACTLY what you have.
Exposed to about 1/3 of the training of the average primary care M.D. (if that), these sorta-doctors function in American medicine with nearly complete autonomy (and are constantly pushing for more).
I have no problem with these relatively new additions to the medical field. I myself criticized my training as too long, redundant and costly while enduring it.
But the more I work with patients who see them, the more I run into decision-making that is flat-out problematic.
I should mention that many P.A.’s I’ve trained with were clearly smarter than me. A couple of the ARNP’s I currently work with are easily as bright or brighter than my – shall we say – earth-friendly mental wattage.
But I’ve learned that smart brains often don’t lead to good medicine. In my opinion, what makes the best medical decision-maker is an acute awareness of ignorance.
You could call it intellectual humility, if you wish. It could be that all the hours of training in medicine really just cultivates this humility to refinement. I can see the value of that.
In the last week, I have dealt with numerous decisions of certainty in medicine that were completely unjustified. All were made by PA’s and ARNP’s. As patients described their experiences, I could tell their previous providers were of the para-doc variety even before they confirmed it for me.
“I’m here for antibiotics, Dr. Secretwave101.”
“Really? What for?”
“I have pneumonia again. I had it 5 times last year. I just have to come in and get antibiotics for it. It’s such a pain!”
“PNEUMONIA? FIVE times in a year? Are you sure? Confirmed by chest X-ray? Do you know the organism? Bacterial each time? Which lung? Was it a particular lobe? Were you hospitalized? Did you have pulmonary scarring as a child?”
“Uhhh. I don’t know any of that stuff. I just need the medicine. I always just come in with this cough and get the medicine.”
Pneumonia is a big freaking deal. Real pneumonia kills people. Like, healthy, not-old, not-sick people. Real pneumonia almost never hits someone 5 times in a year. Once, and you’ve had a tough previous 12 months. You get it 5 times and you’re basically telling me that you’ve spent the previous year in a hospital with chest tubes, IV meals and a bag to catch your pee.
There were two problems with the patient encounter. One, the patient wasn’t well educated by her provider, who clearly had numerous opportunities to clarify things for her over the previous year. She didn’t have pneumonia 5 times, she had a cough.
The provider also never worked up the cough to see what it actually was. No X-rays. No sputum cultures. No pulmonary function tests. Just antibiotics. Broad-spectrum antibiotics.
In another post, I will describe why throwing antibiotics toward a cough with no evidence of bacterial involvement is absolutely catastrophic for the long-term survival of the human species. That statement is a rare instance on this blog where I’m not stating hyperbole, either.
Antibiotic resistance is real, and the results of it will kill you.
I also recently recommended that my sister-in-law take her son into an urgent care center to be evaluated for what sounded like strep throat. That would be, Streptococcus Group A pharyngitis.
“Did you know,” I asked her, “why we treat strep throat?”
“Well, he could get really sick, right?”
“Yes, but not from the throat infection.”
“So, we’re not treating the throat?”
“No. That goes away. Most pharyngitis is viral and goes away. Even bacterial goes away. We only need to treat one specific cause of pharyngitis, Group A Strep, because it can also cause heart disease, kidney disease and all kinds of other stuff.”
“I didn’t know that.” She replied.
I didn’t either. Not until years into my training.
The next day, I found that my nephew was taken to a P.A. at the local Urgent Care and without a culture or any other objective work up, he is diagnosed with “strep throat” and given antibiotics.
“I don’t even need to test this, the symptoms are so classic.” The “doctor” reportedly said.
Two days later, the boy’s little sister gets sick. There’s no culture from the back of brother’s throat. We have no idea if what he had was viral, bacterial, fungal or nothing at all. He may not have even needed the antibiotics, and likely didn’t have the right ones if he did need them.
Now we have no idea what his sister has. Is it the same thing? Is it something new? I guess we’ll just throw some antibiotic at her, too and say they both had STREP THROAT, even though we have no evidence of this.

Did my nephew's throat look like THIS? Did anyone even look?
Certainty in medicine flat-out leads to bad medical care. Everybody has the urge to think they’ve got this or that totally nailed from time to time. Doctors too. Maybe doctors more than other health professionals.
But my experience so far is that certainty increases with less training.
My warning to you is this: If your health care provider is CERTAIN about your health problems, you don’t have a very good doctor. Humility comes from a wide differential diagnosis.
In nature, the humble survive; the proud die.
