The authors of the study started by surveying 136 ambulatory care facilities near the U.S.-Canada border in Michigan, New York and Washington. It makes sense that Canadians crossing the border for care would favor places close by, right? It turns out, however, that about 80 percent of such facilities saw, on average, fewer than one Canadian per month; about 40 percent had seen none in the preceding year.

Then, the researchers looked at how many Canadians were discharged over a five-year period from acute-care hospitals in the same three states. They found that more than 80 percent of these hospital visits were for emergency or urgent care (that is, tourists who had to go to the emergency room). Only about 20 percent of the visits were for elective procedures or care.

Next, the authors of the study surveyed America’s 20 “best” hospitals — as identified by U.S. News & World Report — on the assumption that if Canadians were going to travel for health care, they would be more likely to go to the best-known and highest-quality facilities. Only one of the 11 hospitals that responded saw more than 60 Canadians in a year. And, again, that included both emergencies and elective care.

Finally, the study’s authors examined data from the 18,000 Canadians who participated in the National Population Health Survey. In the previous year, 90 of those 18,000 Canadians had received care in the United States; only 20 of them, however, reported going to the United States expressively for the purpose of obtaining care.
