Medicare HMOs fail to control costs of colon surgery in elderly patients

A study by University of South Florida researchers found that Medicare HMO beneficiaries who underwent colon resection incurred the same overall hospital charges as traditional Medicare patients, despite shorter hospital stays. The study suggests that Medicare HMOs failed to achieve their cost-saving goal in this instance.

High-flying observatory reveals land changing to desert

Scientists used NASA Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) to analyze vegetation and soil changes in response to rain variation over large areas. They found that long-term decrease in litter cover is the most evident sign of desertification, with significant changes in green vegetation and bare soil areas.

Poison and firearms stored in open endanger visiting kids

A study found that households with parents visiting children's homes are more likely to store firearms unlocked and have poor medication storage practices. Homes with older adults and child visitors tend to have more firearms and less safe storage, but the difference is not statistically significant.

Moving admitted ER patients into inpatient beds faster could significantly increase hospital revenue

Long waits for inpatient beds in emergency departments can lead to significant revenue loss, as delayed care blocks beds that could treat incoming patients. The study found hospitals may lose up to $168,000 in potential revenue per admitted chest pain patient wait, with the annual loss potentially exceeding $1.74 million.
