Well, harrumph then! Danged youngsters.
As to the original topic, I thought actual geriatric specialists were scarce as the proverbial hens teeth. My main observation of geriatric care of MIL her last 8 years (passed at 89) was that she really didn't have decent general (or geriatric) care, but sure got tons of specialist and hospital care. DW was regularly taking her to neurologist, orthopedist, and then last few years it was almost monthly to ER, admittance to hospital, and rehab.
What was always missing IMHO was anyone paying attention to overall trajectory and care; that really fell to us. Yes, I guess some of the reports would make it to the GP but there was never what I would consider to be consultation (and coordination) of all this caregiving. Number of times meds were changed at hospital that previously were shown to cause problems (not allergies but problems). For all the money that was spent those last few years ($100's of thousands no question) it struck me that someone spending 30 minutes with her every few months honestly advising her of her likely outcomes might have made a big difference. Just one person's observation.
