I had a seven week bout with bronchitis recently because the first three doctors I went to insisted "it's viral, there's nothing we can do" without doing a sputum test. When I finally found someone who would give me a Z-pak it cleared up in three days after weeks of misery.
It's also a problem when the system has swung so far the other direction that you can't get medication you actually need.
And god forbid, mom/dad get it. I almost died from some crap my daughter brought home because the doctor sent me home twice with a "suck it up" attitude (after I had been "sucking it up" for nearly two months), until I ended up in the emergency room at 1AM with pneumonia, a massively elevated temp, and a pleural effusion that was so painful I could barely breath. The doctor that sent me home called a couple days later (because they took blood samples and some swabs) with a "we have to see you now" call, at which point I was like, yah thanks a lot for nothing...
At the first level, if a patient goes to a doctor the expectation is the doctor should do something to help. If the doctor says, "sorry there is nothing I can do" the patient will likely leave unhappy and try a different doctor. This leads to things like prescription of antibiotics for viral infections. There is no effective treatment, but patients leave happier with a useless treatment than with a denial.
One thing ignored in the article is that, in this role as a placebo prescription, a longer course of antibiotics outperforms a short course. That is because a longer course gives a viral infection a longer time to clear up on its own.
