"Most recent I could find (1997, so I guess it's way higher now):"
Why guess when all it takes is a quick bit of addition. I assume the figure of 37,776 deaths is from all firearms causes so we can easily add the 2009 numbers for the same and come up with 30,913. I would say that isn't "way higher" but the exact opposite, in fact it's way lower, over 18% or nearly one in five.
"The gunshot and cut/stab totals include U.S. $40 billion and U.S. $13 billion respectively in medical, public services, and work-loss costs."
While not strictly an answer to my question, we can take a stab at it. According to Kaiser, healthcare costs are $2.3 trillion. Using the raw $40 billion without the 18% reduction and keeping in the related but not healthcare costs, such as work-loss, the cost of firearms related as a fraction of the total is 17/1000 or 1.7%. While I'm a bit surprised by the number, perhaps you can explain why a doctor would harp about gun ownership when cardiovascular disease, according to the CDC, "accounts for about $1 of every $6 spent on health care in this country." It isn't about dollars.
I have to admit you have me stymied on the PTSD part as I didn't see any mention of bullets, guns, firearms or anything related to the probability of developing PTSD based on exposure to differing stimuli. It could be because the didn't or couldn't separate such data as pretty much everything comes into the ER and ICU so it may be difficult determining which incident type caused what PTSD rate. On the whole I don't see how the link is relevant to the topic at hand.
"There, it didn't take long to find that information; perhaps it would be a valid point to ask you to research something prior to flaming?"
I'm sure it didn't take long. It never takes long to find any old thing that isn't really pertinent. It does show that studies are a great source of funding and building interesting looking databases may serve to siphon a bit of that funding in a particular direction. Oh, for the record, it wasn't a flame, it was a snark and I love to cook so the heat isn't a problem for me.
