Anecdotally, I’ve often had better luck with younger doctors as well. Not only were they more privy to recent advancements, they don’t seem to carry with them the know-it-all mentality that some older doctors seem to have (that dismissive attitude you speak of). More important than mere exposure to research and continuing education, I think, is the willingness and ability to remain open to ignorance and curiosity… and that’s not just a function of age, but personality and upbringing and training too.
The best doctors I’ve had were humble ones, because they were willing to listen and consider the patient experience before jumping to conclusions. And that isn’t just a “nice to have” matter of having good bedside manners… at least in my case, the older, been-then-done-that doctors sometimes took inappropriate diagnostic shortcuts that excluded significant variables that could’ve helped inform their diagnoses and treatments.
In my particular case, at 40 years old, I’m not particularly healthy or unhealthy, but have suffered from chronic gout since my mid-20s. Several older doctors initially (and then insistently) dismissed it as a diagnostic possibility due to my diet (vegan) and age, though more recent research has shown it to be much more prevalent in some populations (especially Asians) and possessing a big genetic, not just dietary, component. It took many attacks, and several doctors in different cities, to finally get on the right medication for that, and since then it has never recurred. None of the older white doctors considered either factor. It was a younger one who eventually suggested, “All the diagnostic criteria and training I’ve learned tells me you shouldn’t have gout, and I can’t prove that it is or isn’t gout, but I can’t think of anything else it could be. Despite the lack of certainty, I think we should put you on gout medication for a few months as a trial and see how it goes.” It worked. The older ones refused to even entertain it as a possibility, despite multiple recurring attacks in the same toes.
I’ve had similar experiences in other fields of medicine, especially psychiatry and psychology, where the older doctors were not really that interested (or perhaps even aware of) recent changes in diagnostic criteria and treatment modalities, whereas the younger ones would explicitly mention things like “Well, we used to think that ______, but lately we’ve come to realize that _____ and so we’re doing things a little differently now.” (The DSM itself has changed a lot in regards to how the field looks at things like depression, autism, ADHD, sexuality, etc.) And of course there’s the whole trans-affirming or not difference between providers, and that probably has a huge generational component.
Maybe if you’re just dealing with relatively mainstream conditions for the US and are a part of the dominant ethnicity, the older doctors (who would presumably have seen hundreds of those cases) can more quickly get you the right treatment. As someone non-white who’s just entering mid-life, though, my personal (and again, strictly anecdotal) experience strongly favors the younger ones due to their general openness and not-yet-cemented practices. Even if they don’t necessarily keep up with recent research more successfully (who can? there’s so much more that comes out than any one person can reasonably keep up with), they are at least more willing to listen and consider different factors. The older ones weren’t so much.
For many of those same reasons, I tend to prefer women doctors.
My pet theory is that whether they’re younger and/or female, they’ve had to work harder in their educations and careers, and have probably had to put up with some of the same dismissive attitudes from their peers and superiors and are thus (hopefully) less likely to want to inflict the same on their own patients. What they lack in clinical experience, they seem to make up for in empathy and willingness to learn. Knowledge can be gained and research can be read… it’s much harder to convince someone with decades of experience that they maybe don’t know everything. Especially when that suggestion comes from someone younger and less educated than them.
