I went to my local walk in clinic a few years back when I was working 60 hour weeks at my high pressured salaried job.
Having experienced bronchitis in the past when the humidity drops in the fall and I get run down, I could tell that what was mild bronchitis had likely progressed into pneumonia.
The attending physician said no, it's bronchitis and gave me a prescription. Two days later I was MUCH worse and returned to see a different attending physician who changed the diagnosis to pneumonia and changed the treatment.
Anyone can get it wrong, doctors included, and quoting low probability alternate diagnoses as 'proof' while POTENTIALLY accurate, there is NO guarantee that the outcome would be different.
I can pass on other experiences that occurred with my parents (a general surgeon/family physician treating my father for a cardiac condition and a family history of heart disease), but bottom line, quality care is dependent on the individual.
Doctors need to get over the scare tactics.
