Decrease in Pediatric Antibiotic Leveling Off
The number of children taking antibiotics has decreased over the past decade, but that decrease has stalled in recent years in certain age groups and geographic locations, according to a study in Pediatrics. Researchers reviewed pharmacy and outpatient claims over a 10-year period (2000 to 2010) in three health plans located in three different geographic locations to determine the number of antibiotics dispensed each year for children ages 3 months to 18 years. Although the overall antibiotic-dispensing rate in each age group and health plan was lower in 2009-2010 than in 2000-2001, the rate of decline in antibiotic use has slowed. The highest rate of antibiotic use was in children age 3 months to less than 24 months of age in all years of the study.
The study authors say the previous downward trend in antibiotic use in children may have reached a plateau, and continued improvements in judicious antibiotic dispensing are needed. Read more on pediatrics.
NHTSA Gives Okay for Vehicle to Vehicle Communication to Help Prevent Crashes
The National Highway Traffic Safety Administration has announced that it will begin taking steps to allow vehicle-to-vehicle (V2V) communication technology for light vehicles, which will allow vehicles to "talk" to each other and ultimately avoid many crashes by exchanging basic safety data, such as speed and position, ten times per second.
The safety applications currently being developed provide warnings to drivers so that they can prevent imminent collisions, but do not automatically operate any vehicle systems, such as braking or steering, although NHTSA is also considering future actions on active safety technologies that rely on on-board sensors.
V2V communications can provide the vehicle and driver with 360-degree situational awareness to address additional crash situations — including those, for example, in which a driver needs to decide if it is safe to pass on a two-lane road (potential head-on collision), make a left turn across the path of oncoming traffic, or in which a vehicle approaching at an intersection appears to be on a collision course. In those situations, V2V communications can detect threats hundreds of yards from other vehicles that cannot be seen, often in situations in which on-board sensors alone cannot detect the threat.

Many Hospital ICUs Don't Follow Infection Prevention Rules
While most hospitals have evidence-based guidelines in place to prevent health care-associated infections in intensive care units (ICUs), clinicians often fail to follow them according to new research from the Columbia University School of Nursing published in the American Journal of Infection Control. The study, on over 1600 ICUs, found lax compliance in intensive care units where patients are more likely to be treated with devices linked to preventable infections – such as central lines, urinary catheters and ventilators.
The study focused on three of the most common preventable infections — central line-associated bloodstream infections, ventilator-associated pneumonia, and catheter-associated urinary tract infections and determined that despite decades of research, establishing best practices for prevention of these infections, approximately one in 10 hospitals lack checklists to prevent bloodstream infections, and one in four lack checklists to help avoid pneumonia in ventilator patients, and that in hospitals with checklists, they are followed only about half of the time.
Health care-associated infections kill an estimated 100,000 Americans a year and result in over $30 billion in excess medical costs, according to the Centers for Disease Control and Prevention. Read more on injury prevention.
