Agree about poor sens and spec but improving it requires dedicated independent feedback which is not done nor practical. Also, HPI >>> PE, especially with continuity care.
If the physical exam were a lab or image test, weād never order it. Not sensitive or specific enough. Yet there are those that hold onto these quaint ideas about the exam.
And I do an exam. Focused. I wonāt be counting moles or look at your pubic hair distribution. But.
For the exam to improve sensitivity and specificity you need clinical experience and expertise. Variables we all know exist but people donāt want to talk much about here because it seriously changes the calculus on predictability and magnitude of effect. We like things neater and tidier.
Medicine also generally abhors intuition or admitting that those with good intuition have a style that should be developed and nurtured.
The best clinicians are either HIGHLY intuitive (rare) or they have all the details and data points memorized (uncommon). I donāt have any problems with the detail memorizers. I understand how and why they exist. But they seem to despise my style of intuitive approach because they can never understand it.
I can tell a lot about you from the door when you show up in my ICU. And thatās totally fine. Itās not an argument against using an exam. And you often need an exam of some limited capacity. Sometimes more. The skin can tell you a lot. And itās also probably the trickiest. Iāll never pretend to be Superman skin diagnostician.
Maybe the most important reason to do an exam. Especially in clinic. Patients like it. Expect it. Think it means more than it does. Assign a value to it much higher than it deserves because they donāt understand the bigger contexts. And many are not sophisticated enough to understand the nuance discussed here. That just is. Itās not good or bad.
