I’m doing early discovery for a potential cross-border healthcare coordination service (patients traveling abroad for treatment), and I want to understand the real failure modes before assuming this is even solvable.

From the outside, it looks like a mix of hospital selection, intermediary incentives, pricing opacity, logistics, and post-treatment follow-up — but I suspect the hardest problems are less obvious.

For people who’ve seen this firsthand (patients, family members, clinicians, hospital admins, or operators):

Where does this process usually break down in practice?

What risks or incentives are most commonly underestimated?

What parts cause the most harm when done poorly?
