En Español| How does the U.S. health care system stack up against Canada’s? You’ve probably heard allegedly true horror stories about the Canadian system — like 340-day waits for knee replacement surgery, for example.

To separate fact from fiction, Aaron E. Carroll, M.D., the director of the Center for Health Policy and Professionalism Research in Indianapolis, identified the top myths about the two health care systems.

Myth #1: Canadians are flocking to the United States to get medical care.

How many times have you heard that Canadians, frustrated by long wait times and rationing where they live, come to the United States for medical care? 

I don’t deny that some well-off people might come to the United States for medical care. If I needed a heart or lung transplant, there’s no place I’d rather have it done. But for the vast, vast majority of people, that’s not happening.

The most comprehensive study I’ve seen on this topic — it employed three different methodologies, all with solid rationales behind them — was published in the peer-reviewed journal Health Affairs.

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.
