1/Time for a #UncleBob screed. The question Andrew raises is a very interesting one. First I must provide my understanding of the purpose of teaching ward attending physicians.
I divide this into providing excellent patient care & helping learners grow.
2/ Providing high quality care is a given. Excellent ward attendings evolve with clinical practice (consider the 10,000 hour "rule"). But I would argue that both outpatient clinical practice and inpatient practice are beneficial.
3/ And I believe I learn more in a month of ward attending than if I did a month of solo patient care. Patient care requires attention to detail, diagnostic excellence, management efficiency and proper use of tests and consultants.
4/ Experience does matter - but doing hospitalist work may or may not help. We all need deliberate practice - and if we strive for that, teaching attending physicians who are involved in patient care grow just as fast or (IMHO) faster than solo hospitalists.
5/ Now for the second half of the job - helping learners grow. We teach students, interns and residents internal medicine. The best educators help all grow. Research tells us that learners want to know how we think. That is part of becoming an experienced educator.
6/ Some in this thread have emphasized system aspects - d/c planning, d/c notes/, billing, med rec, orders. Yet when you learn those skills at one hospital and work at a different hospital your really have to start all over.
7/ I have taught in 2 University hospitals, a VA and a community hospital. The systems are all different as are the computer systems. Our residents become skilled and quickly teach this to our interns. Most of our residents do not become hospitalists.
8/ Spending time on these system issues must then take time away from teaching medicine - the raison d'etre of medical school and residency. We desperately need the best educators who can share their wisdom as well as their knowledge.
9/ I learned more about bedside manner from my 15 years doing outpatient medicine than I ever learned in hospital medicine. The dichotomization of internal medicine into inpatient and outpatient may have a negative impact on education - but that is just conjecture to rile.
10/ “You have your way. I have my way. As for the right way, the correct way, and the only way, it does not exist.”― Friedrich Wilhelm Nietzsche
We need educators 2 bring different skills to ward attending. Please avoid the argument that one road takes a superior path 2 another

1/ #UncleBob recently presented a patient who had a hyperkalemia, normal gap acidosis (type 4 RTA) to @DxRxEdu & @rabihmgeha

But why does hyperkalemia cause a normal gap acidosis?

@tony_breu
2/ Some basic physiology - we metabolize around 1 mEq of H+ daily from our diet. We buffer that acid using titratable (phosphate) and non-titratable (NH4+) acids.
The phosphate pathway does not vary much, but our kidneys can normally control the ammonium pathway
3/ Where does the ammonia come from? Glutamine -> glutamate under the enzyme glutaminase produces NH3

Here is the interesting part. Increased K inhibits this enzyme, thus we produce insufficient NH3 to buffer our dietary intake.

#UncleBob posted this link yesterday. Here are a few thoughts on the article. “I don’t know what’s the matter with people: they don’t learn by understanding; they learn by some other way—by rote or something. Their knowledge is so fragile!”

— Richard Feynman

Reminds me of M1&2
"The difference between reasoning by first principles and reasoning by analogy is like the difference between being a chef and being a cook. If the cook lost the recipe, he’d be screwed."

This is so relevant to those who grow and those who stagnate.
"Some of us are naturally skeptical of what we’re told. Maybe it doesn’t match up to our experiences. Maybe it’s something that used to be true but isn’t true anymore. And maybe we just think very differently about something." - The best diagnosticians always question previous dx

1/ Here is the story - hopefully instructive. Patient (ESRD w/ dialysis) admitted 3 weeks previously for dyspnea. Portable CXR shows small pleural effusion & some haziness - pneumonia or atelectasis. No fever, no increased WBC, no productive cough. Discussed now w/ radiology
2/ Radiologist teaches our team - pneumonia is a CLINICAL DIAGNOSIS - cannot make the diagnosis by CXR/CT scan.

Patient discharged - readmitted for more dyspnea - now with moderate pericardial effusion and large left pleural effusion. Receive furosemide & then thoracentesis
3/
fluid LDH - 136
fluid TP. - 3.8
serum LDH - 212
serum TP - 5.6

Fluid very clear - pH 7.43 - no WBCs

Light's criteria - exudative effusion

All appropriate pleural fluid studies negative

1/ #UncleBob hopes those on the fence about vaccines will understand this
Weekly COVID-19 death rate via CDC:

Unvaccinated: 9.7 deaths per 100k
Fully vaccinated: 0.7 deaths per 100k
Boosted: 0.1 deaths per 100k
2/ Yes you can get omicron even if you are boosted

BUT

You are less likely to get infected
If you get infected you are much less likely to need hospitalization
If you need hospitalization, you are much less likely to need ICU care, and MUCH less likely to die
3/ Would you turn down medical care if you got sick?

I assume no - almost everyone comes to the hospital and ask for everything

Then why would you not accept a free prevention tool?

1/ #UncleBob has tips for newly minted clinician-educators. Today I will focus on teaching how to take and present the history. #MedEd
@uabimres @UABGIM @SocietyGIM @ACPinternists
2/ Learn to define and expand patient words - e.g., diarrhea (how often, what color, interfere with sleep, etc.). Patients describe things in words they understand, but often we interpret those words differently. Many such examples: chest pain, dyspnea, weakness, SOB, PND
3/ Try to understand the chronology and use that during presentation. This requires careful questioning so that the learner really understands the chronology.

1/ #UncleBob has many thoughts about this tragic tale of diagnostic errors!

2/ In the very first aliquot we learn that we have a college student with throat pain and chills. We do not know if they were simple chills or rigors. This is actually a BIG DEAL. Rigors (shaking chills) have a high odds ratio for bacteremia.
3/ If she really had rigors, then she needed blood cultures and admission for likely bacteremia. Interesting that she had unilateral tonsillar swelling. I have only seen this once in a patient with Fusobacterium tonsillitis with bacteremia! No data, just an observation
