I think every hospital in the country would have someone who could do this. It's a question of whether they have someone who's funded to do this.
The recommendation is that every hospital that has an active critical care unit should have someone. In fact, in jurisdictions like Spain and such, that's actually the case, so they have many more of these sorts of physicians. Whenever the potential for donation comes up, there is someone who is knowledgeable in the area and comfortable in the area to take the lead in that process.
