The costs of caring for elderly Florida patients hospitalized for colon surgery are not reduced by Medicare HMOs, report University of South Florida researchers in the December issue of the Archives of Surgery.
Despite significantly shorter hospital stays, Medicare HMO beneficiaries who underwent colon resections -- surgery to remove a diseased section of the large intestines -- incurred the same overall hospital charges as patients covered by traditional fee-for-service Medicare. Consequently, the study found, daily hospital charges for the Medicare HMO group were higher than for the traditional Medicare group. The researchers assumed a direct relationship between hospital charges, available from the Agency for Health Care Administrations Florida database, and actual costs, which are difficult to obtain from hospital executives.
"The Medicare HMO model failed as a cost-saving measure in this particular instance," said the studys principal investigator Michel Murr, MD, an associate professor of surgery in the USF College of Medicine. "Our finding appears to be confirmed by the recent departure of major HMOs from the Medicare market in Florida."

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
