Surveys of people "considering" or "planning" to do things are notoriously inaccurate. You have to look at the number of people who actually did do the thing in question.

Your source shows ~375k to 2m non-business bankruptcies filed per year over the last twenty years, not all of which is primarily due to medical costs (but there appears to not be a definitive source of data on this), out of a population that went from 282m to 331m over the same time. So 0.1-0.7% of the population files for a personal bankruptcy every year for any reason, which is a far cry from one quarter of the country being on a brink of a medical bankruptcy.

Everyone knows healthcare costs are problematic in this country; no need to resort to hyperbole. Let's stick to the facts.
