Based on the reports published by leading researchers, over a third of all the patients that went to 37 health clinics in the state of Colorado on a single day turned out to be uninsured. This realization exposes the possibility that close to one and a half million people in the entire state could also suffer from a lack of adequate coverage.

Conducting the survey on a voluntary basis was the University of Colorado Denver School of Medicine, which collected information among patients who had private insurance, Medicare or Medicaid. Their research showed an alarming figure: over 36% of the 948 that were surveyed were underinsured.
