OP-ED

Not Knowing What You Don’t Know

“The more you learn, the more you realize you don’t know.”

You will hear this statement not just from physicians, but from lots of other folks engaged in scholarly work of all stripes. That’s because it is not merely true; it is a deep and universal truth that permeates all of mankind’s intellectual endeavors.

The implication of this for the practice of medicine is that a little knowledge can be very dangerous.

What do I, as a fully trained, extensively experienced primary care physician bring to the evaluation of patients who seek out my care that cannot be matched by so-called “mid-level providers” (PAs and NPs)? It is not (always) my knowledge, but rather the experience to know when I do not know something. In short, I know when to ask someone else’s opinion in consultation or referral.

I had a scary experience lately with a PA who didn’t even know what she didn’t know (and who still probably doesn’t realize it.)

The patient had been bit on the hand by a cat. I saw the injury approximately 9 hours after it had occurred. The patient had cleaned it thoroughly as soon as it had happened, and by the time I saw it, it was still clean, bleeding freely, not particularly red or swollen, and only a little painful. Still; cat bites are nasty, especially on the hands. Therefore I began treatment with oral amoxicillin-clavulanate, and told the patient to soak it in hot water several times a day.

Six hours later (after one oral dose of antibiotic) the patient called me back: the wound was now much more painful, red, swollen, and there were red streaks going from the hand all the way up to his elbow. Frankly, I was a little puzzled. He was already on antibiotics; the single dose probably hadn’t had enough time to make much of an impact. And yet the infection was clearly progressing.

I called my handy dandy Hand man, my friend the hand surgeon I have on speed dial, whom I love because he answers my texts. This time, though, I picked up the phone and spoke to him. I explained the situation and my puzzlement. Here’s what he said:

Send him to the ER. He needs to admitted for IV antibiotics for 24 hours. If it’s not getting better by then, he needs a debridement [surgical procedure].

Okay then.

I called my patient and relayed the message. Just to be sure, though, I asked him to call me if they did NOT admit him.

On I went with my day.

Phone rings; it’s my patient calling from the ER:

They’re sending me home.

What?

They’re giving me a dose of IV antibiotics and sending me home on the one you gave me. They gave me the number of a hand surgeon to call tomorrow if it’s not better.

Hm.

I get on the phone to the ER, and ask to speak to the physician seeing my patient. Turns out it’s a PA, who proceeds to tell me that the hand doesn’t really look all that bad, she’s seen worse, and treated them like this before, sending them out with the blessing of the hand surgeon.

Hm. This is a fast moving infection that has worsened markedly in the last six hours while on oral antibiotics.

Did you consult Hand? I ask.

No.

Hm.

Long story short, I get the PA to call Hand Surgery (“Though I doubt they’ll come in,”) who successfully convinces the ER to admit the patient on 23 hour observation status with IV antibiotics. By morning (and 4 doses of IV antibiotics), the red streaks are resolving, the swelling and pain are decreasing, and the patient is good to go, to complete the course of orals.

I was concerned enough about this encounter to call the ER and speak to someone *in charge*. As part of our go-round, I was informed that there was always an ER physician available while the PA was seeing patients if there had been any concern, to whom the PA could turn. It was surprisingly difficult to convey the idea that the problem was that the PA did NOT have a concern. She did not believe that she needed to consult either with her supervising physician, or a specialist.

If I had not explained the (expected) plan to my patient, or specifically asked him to call if the plan was not carried out, or if I had meekly acquiesced to the “provider” on site since she was looking at the patient and I wasn’t (though the patient did take and send me a picture, which I was able to compare to one I took of the same injury 6 hours earlier), frankly I shudder to contemplate the outcome.

Primary care isn’t just about knowing stuff, and knowing what you know; more than that, it’s knowing enough to know what you don’t know.

Mid-level providers do not know enough to know what they don’t know. This makes them dangerous. Admittedly these situations are few and far between, which is what allows complacency to flourish. But make no mistake. Their education emphasizes what they know, leaving them with enormous blind spots of hubris into which more and more patients will fall, with predictably disastrous results.

The gambling sector, the pillar of Macau’s economy, earned a record 108.7 billion patacas (US$13.7 billion) in revenues last year, an increase of 31 percent year on year, according to government figures. But the figure was down 12 percent year on year in the first half of 2009 due to the economic downturn.

No, I am not a physician. I am not a wanna-be physician, ,I am not a mid-level, a physician extender, etc. I am a NURSE with extensive education, clinical training and expertise. Sadly, I feel that some physicians are under the impression that we are trying to replace or compete with them. Although there are always a few bad apples in the bunch, I believe that most Nurse Practitioners know what they don’t know and refer their patients appropriately. As we are not in this profession for the kudos, but for the patient. The original post was offensive on at… Read more »

Lucy, shame on you. You are afraid of the np/pa taking your job so you demonize them. Shame on you.

Dr. Dinosaur nice post and great experience, good sense of arranging the whole incidence in a manner so as to directly strike on to reader’s mind.

I am always surprised that one of the anti-PA diatribes seems to assume that once their truncated educational program ends, they no longer learn. Yes, their traiing is considerably shorter and yes, you would be ill-advised to leave a new PA graduate to their own devices but for heaven’s sake people, just as we continued lo learn during and post-residency, so have they. I’ve never met a new grad PA who wanted to practice independently – in fact they are usually attached to my hip. But give the one who’s been out 5 years and has 10,000 hours under their… Read more »

Dear Dr Dinosaur, I too had a few very similar experiences. One was with a pt that came into my family practice office w/an obvious case of advanced cellulitis of right lower leg. I advised the pt to go to the local ED which he did w/ his wife. I advised he will need IV abx and quite possibly be admitted. Upon arriving at the ED they waited 3 1/2 hrs before being seen and promptly was Dx and given ceftriaxone 250mg IM and amoxicillin 500mg q8hr and keep elevated. When I called the pt wife later that night she… Read more »

The PA may have made a mistake. We don’t have enough information and first-hand knowledge of the situation to definitely confirm this. However, I can say that IF the PA did indeed make a bad call, it wasn’t because they are a PA, specifically. Medical clinicians of all types (MD, DO, PA, NP) all make mistakes and bad calls. It was because they were human and maybe not that great of a clinician. It happens across the board, irregardless of your degree. PAs are more than capable medical providers; dont undermine the training they have just because they “didn’t go… Read more »

” And the cases that the PAs are seeing and that docs are seeing are NOT the same types of cases. I seriously doubt that one can easily “statistically correct” for such a profound difference in case mix.” There are many rural facilities that only staff PAs seeing everything that comes in the door and others that are dual pa/md with both providers alternating charts regardless of acuity. During one of my last shifts at my rural job I was intubating a polysubstance overdose while the doc was seeing a kid with a cough and fever. . see here for… Read more »

emedpa,

That is not how things work at the ERs I cover. Hence that is not what my observations are based on.

Dr Research, PA-C, I don’t think we are as far apart as you might think. I am not a PA or Nurse “hater” and I think some of what is going on is the “playing” of one group (MDs) against another group (PAs, NPs) by our “fearless leaders”. As I said before, some docs see PAs the way some blue collar workers see Mexicans – as a low paid threat to their livliehood. I remember some of the most valuable lessons I learned about how to read IVPs (an archaic study of the kidneys) were from an experienced X-Ray tech… Read more »

Recall that many of the MDs during their clinical rotations RELIED on the very RNs, NPs and PAs they are denigrating to assit them in their learning- and vice versa.
Last time I checked, aside from my multiple degrees, years of education, and decades of eperience – the initials after my name or those of my physician colleagues did not render us omnicient or infallible.
Let’s stop the denigration and back-biting and work together as a team to care for the patient- and stop worrying about who knows more– together we know a lot!

I love the scientific analysis and discussion of a study with a N of 1. Evidence not opinion is what is necessary. You know what they say about opinions; they are much like an anus, everyone has one and no one thinks theirs stinks.

Life is short, the are is long, and your logic is less than impressive. 1. Who is to say that the patient would not have had a successful outcome with the treatment course the PA had prescribed? Perhaps a single dose of antibiotics would have gotten the patient over the hump so to speak – and at less time and cost to the patient and the healthcare system. Your supposition that having a physician’s involvement produced some sort of deus ex machina ending is purely a supposition. Furthermore, maybe everyone was malpracticing here? Some regard it as standard practice to… Read more »
