Walgreens, the country’s largest drugstore chain, announced on April 4th that its 330+ Take Care Clinics will be the first retail store clinics to both diagnose and manage chronic conditions like asthma, diabetes, high blood pressure, and high cholesterol. The Nurse Practitioners (NPs) and Physician Assistants (PAs) who staff these clinics will provide an entry point into treatment for some of these conditions, setting Walgreens apart from competitors like Target and CVS whose staff help manage already-established chronic illnesses or are limited to testing for and treating minor, short-lived ailments like strep throat.
A one-stop shop for toothpaste, prescription drugs, and a diabetes diagnosis? The retail clinic phenomenon has its appeal: it allows patients convenience and better access to care through longer hours and more locations than our health care system now provides. Walgreens leaders bill their latest offering as a complementary service to traditional medical care. They envision close collaboration with physicians and even inclusion in Accountable Care Organizations, according to reporting by Forbes’ Bruce Japsen (though it’s not clear how the retailer would share the financial risk or savings in such a model).
“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.
