Sustained feedback to doctors may help maintain appropriate antibiotic usage in children

CHOP experts: Benefits may fade after end of audit and feedback to clinicians

2014-10-14

(Press-News.org) A program that provides guidance to primary care physicians about appropriately prescribing antibiotics for children is effective, but its improvements wear off after regular auditing and feedback are discontinued.

"Our findings suggest that interventions with outpatient healthcare providers should include continued feedback to clinicians to remain effective," said study leader Jeffrey S. Gerber, M.D., Ph.D., an infectious diseases specialist at The Children's Hospital of Philadelphia (CHOP).

Gerber and colleagues from CHOP published their research online Oct. 10 in the Journal of the American Medical Association and presented their findings the same day at the IDWeek 2014 meeting in Philadelphia. IDWeek is an annual meeting of infectious diseases specialists.

Because disease-causing microorganisms have been developing resistance to commonly used antibiotics, public health experts advocate more selective usage of those medications. The "antimicrobial stewardship" program in the current study included prospective audits of prescription patterns--evaluating prescriptions based on current prescribing guidelines for specific conditions issued by professional organizations. The program staff then provided personalized, private feedback reports to the practitioners, advising them whether their prescriptions followed current recommendations.

The study team analyzed electronic health records of 1.2 million office visits at 18 community-based primary care offices within the CHOP pediatric network, focusing on prescriptions for common bacterial respiratory infections in children. The researchers randomized the 18 practices into two groups—one receiving the intervention (an hour-long session of clinician education, followed by audit and feedback) and the other group receiving no intervention.

The researchers previously reported in June 2013 that inappropriate prescribing decreased significantly in the intervention group, from 26.8 percent to 14.3 percent, compared to a decrease from 28.4 percent to 22.6 percent in the control group.

Because the previous study covered a 12-month intervention period, the current study evaluated the durability of the effects. The team followed antibiotic prescription patterns for 18 months after the auditing and feedback ended.

Prescribing of broad-spectrum antibiotics, which according to guidelines are typically reserved as second-line treatments, increased over the extended time period, reverting to above-baseline levels. After adjusting the data set for the additional 18 months after intervention ended, the study team found inappropriate prescribing rose from 16.7 percent to 27.9 percent in the intervention group, and from 25.4 percent to 30.2 percent in controls.

"Our results suggest that audit and feedback were crucial parts of this intervention," said Gerber, who added, "For the initial benefits of this program to persist, there needs to be continued, active feedback to the clinicians in primary care offices."

Earliest-known lamprey larva fossils unearthed in Inner Mongolia

2014-10-14

LAWRENCE — Few people devote time to pondering the ancient origins of the eel-like lamprey, yet the evolutionary saga of the bloodsucker holds essential clues to the biological roots of humanity. Today, the Proceedings of the National Academy of Sciences published a description of fossilized lamprey larvae that date back to the Lower Cretaceous — at least 65 million years ago. They're the oldest identified fossils displaying the creature in stages of pre-metamorphosis and metamorphosis. "Among animals with backbones, everything, including us, evolved from ...

Stress may be harder on women's hearts than men's

2014-10-14

DURHAM, N.C. -- Researchers have known for decades that stress contributes to heart disease. But a new analysis by researchers at Duke Medicine shows mental stress may tax women's hearts more than men's. The research appears online Oct. 13, 2014, in the Journal of the American College of Cardiology. "Normally when under stress, we fight back or run away. In order to do that, we need to pump more blood to the body," said Wei Jiang, M.D., the study's senior author and professor of medicine, psychiatry and behavioral sciences at the Duke University School of Medicine. ...

Beyond LEDs: Brighter, new energy-saving flat panel lights based on carbon nanotubes

2014-10-14

Washington D.C., October 14, 2014 -- Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue unabated to search for the even-better-bulbs of tomorrow. Enter carbon electronics. Electronics based on carbon, especially carbon nanotubes (CNTs), are emerging as successors to silicon for making semiconductor materials. And they may enable a new generation of brighter, low-power, low-cost lighting devices that could challenge ...

New treatment target identified for aggressive breast cancer

2014-10-14

AUGUSTA, Ga. – One of the first-known oncogenes has a protein partner that helps breast cancer proliferate and when it's blocked, so is the cancer, scientists report. The gene ErbB2, commonly called HER2, is highly expressed in about 25 percent of breast cancers. Scientists have now found the protein Erbin, thought to be an anti-tumor factor, also is highly expressed in these cancers and essential to ErbB2's support of breast cancer. When scientists interfere with the interaction between the two in mice, it inhibits tumor development and the usual spread to the ...

However, when it comes to purchasing and consuming products normally ...

Country of origin: Are negative stereotypes always bad for business?

2014-10-14

Consumers worldwide associate France with fashion and luxury and are willing to pay a lot for French luxury products such as perfume and wine. But what about products made in countries with less favorable reputations? A new study in the Journal of Consumer Research shows that consumers won't judge a country's products by its reputation if the products are well-made. "Positive feelings about a country don't always translate into more favorable opinions of its products. A positive opinion of a country may actually make consumers think more about whether or not the country ...
