I would say that the standard of care is generally pretty darned good, so don't let him wind you up. On the other hand, the NHS has an inbuilt economic conundrum - always more people taking out than putting in, which must result in a shortfall, putting doctors and nurses under some extra strain that doesn't generally happen in the US under the private healthcare-as-a-business model (i.e. less funding for expensive procedures, limits on time allotted for spending with individual patients). Some sacrifices and compromises have to be made, just as they would in the US under an HMO. And occasionally this can mean that early diagnosis doesn't happen with rare conditions. But individual quality of care varies widely - I wouldn't make a blanket statement about the NHS being awful, just as I wouldn't about the US medical system. There are outstanding doctors in both places and there are awful doctors who will fob you off in both places. The best thing you can do, in either country, is take personal responsibility and be a good advocate for your own healthcare.
