The authors cite papers in their intro that says NCI designated centers have better post-op mortality and better survival outcomes than non-NCI designated cancer centers.
They do not refute any of these claims from the cited papers in the introduction within the paper. There is one line about this as a future study - "Further research examining hospital-level differences in long-term postsurgical outcomes, such as mortality, paired with spending outcomes, is necessary to judge whether and under what circumstances the premium price of NCI centers is justified."
Anyone who believes in or works at an NCI simply responds with: "OK well it's more expensive, but we have less post op mortality AND our survival outcomes are better! Who cares if a patient gets re-admitted or not if they're more likely to have their cancer recur and die from it because the surgeons at those non-NCI places are so bad! Would you be willing to pay more to have a higher chance of surviving in the short and long term after your cancer surgery? Because that's what you get when you come to your local NCI cancer center!"
I do like their limitaitons section (bolded my emphasis) - "First, the analysis was limited to patients with private insurance undergoing cancer-directed surgery for breast, colon, or lung cancer, and may not generalize to patients with other malignant neoplasms or those receiving nonsurgical cancer care. However, these are 3 of the 4 most common incident cancers and make up most of cancer surgical volumes nationally, suggesting that our results may at least extend to other oncologic surgical populations."
"We included all of the most common cancers. Except prostate cancer. Because there's a Urologist on the paper. And he said if we include our collected prostate data (which says the same thing, probably), he wouldn't want to be co-author on it. And then we'd have zero surgeons. About a paper that says our own facility gets paid more for their surgery without any savings in terms of less toxicities/re-admissions, etc. Which wouldn't be a good look. So we had to have a surgeon. So we scrapped the prostate data. And plus some of those folks pick radiation so if you're going to skip one, might as well make it that one."
