Uninsured

New and noteworthy

Quote from KFF President and CEO Drew Altman reads, "when it comes to the “affordability crisis” driving the national discussion of health care today, the chronically ill, and most of all the chronically ill uninsured, are the tip of the spear."

The Group that Struggles the Most in American Health Care

In a new column, Dr. Drew Altman, KFF’s Founding President and CEO, previews findings about the chronically ill uninsured from a large KFF survey of 25,000 Americans focusing on the cost and access challenges facing the chronically ill, which will be released tomorrow. He writes: “There are more than enough needs to go around in American health care, but if I had to pick the one group that struggles the most with costs and access, it would be people with chronic illnesses who are also uninsured.”
