Nearly one in four people (22.7%) report having had trouble paying medical bills during the past year, according to a survey conducted in May by the Robert Wood Johnson Foundation. The survey also found that almost a quarter (22.4%) report that they or a family member delayed seeing a doctor when it was necessary because of concerns about cost. The Robert Wood Johnson Foundation Health Care Consumer Confidence Index is described as the first-ever monthly measure of consumer confidence in American health care. It will be released the third week of every month.
