Actually it says it does. But you'd have to read it first to know that. It just doesn't save enough to completely pay for Government's cost for the health care reform package in a 10 year window that the CBO used.
The new research offers them added ammunition, arguing that the 10-year horizon typically used by CBO analysts is too brief to capture the savings that eventually result from improved public health. The authors -- who include two University of Chicago medical professors as well as O'Grady and James C. Capretta, who both served for years in various health policy positions in Washington -- suggest that the CBO instead use a 25-year "budget window" to calculate the cost of prevention programs.
"I'm trying to show them that there are other ways to do this, as we face these new challenges from the epidemic of chronic illness," he said. "They're used to thinking like economists. And their friends at Health and Human Services are used to thinking like actuaries. But there's this third way, which is epidemiological, which shows us how a disease progresses over time."
It doesn't actually say what you said it says. (whew.)
IT says that in order for the preventative care to save costs overall, you have to have more than a 25 year recovery period. For many diabetics, they will not live long enough to recover that cost...i.e. the type 2 diagnosis comes too late in life. That's the reference about "young" diabetics in the article, and also the bars in the graph Vetteguy posted.
For people who don't live 25 years, the preventive care costs more than it saves.
