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."

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
