Penn study finds link between physician training and brand name prescribing

Internal medicine residents are twice as likely to prescribe most expensive statins when senior physicians do

2015-07-23
(Press-News.org) PHILADELPHIA - Physicians in training are twice as likely to order a costly brand-name statin (used to lower blood cholesterol levels) when supervised by senior physicians who prefer those medications in their own practice, according to a new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania and published online in the Journal of General Internal Medicine. These findings document a link between low-value prescribing and graduate medical training, which physicians undergo after completing medical school but before they can practice independently.

As part of this study of 10,151 statin prescriptions across four sites, lead author Kira Ryskina, MD, a general internal medicine fellow at Penn, and her coauthors analyzed prescribing data from 342 resident and 42 attending physicians from 2007 to 2011. The study found that the probability of a resident prescribing a costly brand-name statin increased from 22.6 percent when residents were supervised by attending physicians who mostly prescribed cheaper generic statins, to 41.6 percent when they were supervised by an attending who mostly prescribed expensive brand name statins. The linkage was strongest for the most junior resident physicians in training. With brand name statin prescribing accounting for an estimated $5.8 billion in low-value spending annually, these findings represent an opportunity for improvement in graduate medical education to increase value in health care spending.

"These findings provide early empirical evidence that low-value practices among physicians are transferred from teachers to trainees, highlighting the importance of re-design of graduate medical education," said Ryskina. "We observed considerable variation in the prescribing practices of both attending physicians and residents, suggesting room to improve cost-effectiveness."

The study's other Penn authors include C. Jessica Dine, MD, an assistant professor of Pulmonary and Critical Care Medicine, and Andrew Epstein, PhD, a research associate professor in the division of General Internal Medicine, along with other co-authors Esther J. Kim, BS, and Tara F. Bishop MD, MPH.

Small oxygen jump helped enable early animals take first breaths

2015-07-23
If oxygen was a driver of the early evolution of animals, only a slight bump in oxygen levels facilitated it, according to a multi-institutional research team that includes a Virginia Tech geoscientist. The discovery, published Wednesday in the journal Nature, calls into question the long held theory that a dramatic change in oxygen levels might have been responsible for the appearance of complicated life forms like whales, sharks, and squids evolving from less complicated life forms, such as microorganisms, algae, and sponges. The researchers discovered oxygen levels ...

Mayo researchers decode molecular action of combination therapy for deadly thyroid cancer

2015-07-23
JACKSONVILLE, Fla. -- In their bid to find the best combination of therapies to treat anaplastic thyroid cancer (ATC), researchers on Mayo Clinic's Florida campus demonstrated that all histone deacetylase (HDAC) inhibitors are not created equal. In testing multiple HDAC inhibitors in combination with the chemotherapy drug paclitaxel, known to give some benefit for this aggressive cancer, they found that class II HDAC inhibitors signal through a newly discovered pathway to promote synergy with chemotherapy treatment. They say their study, published online today in Endocrine ...

These satellites fly through the Van Allen radiation belts -- giant concentric layers of charged particles held in place by the Earth's ...

Expert panel sets nutrition guidelines to manage GI symptoms in autism

2015-07-23
A new guideline for the nutrition of management gastrointestinal symptoms in children with autism spectrum disorders (ASD) provides a framework for clinicians to navigate frequently seen issues such as food selectivity, alternative diets and nutritional deficits. The expert panel was convened at Marcus Autism Center, an affiliate of Children's Healthcare of Atlanta and the resulting guideline was published online by the Journal of the Academy of Nutrition and Dietetics (JAND). "Children with autism are at increased risk for feeding and gastrointestinal (GI) concerns compared ...

How much does diet affect the cancer patient? Do "antioxidants" really play an important role in health - or are they causing more cancers than they cure? And what exactly is the relationship between obesity and cancer? The latest Special Issue in ecancermedicalscience collects four original articles from experts in cancer and metabolism, addressing the hottest areas of research in this rapidly developing field. "In our clinical practice, cancer patients often ask 'Doctor, is there something specific I should eat or avoid eating?'" says Guest Editor of this Special ...

Researchers: Body fat can send signals to brain, affecting stress response

2015-07-23
The brain's effect on other parts of the body has been well established. Now, a group that includes two University of Florida Health researchers has found that it's a two-way street: Body fat can send a signal that affects the way the brain deals with stress and metabolism. While the exact nature of those signals remains a mystery, researchers say simply knowing such a pathway exists and learning more about it could help break a vicious cycle: Stress causes a desire to eat more, which can lead to obesity. And too much extra fat can impair the body's ability to send a ...

Same genes may influence GCSE results across range of subjects

2015-07-23
Many of the same genes may affect GCSE results across a broad range of subjects according to a new study from the Institute of Psychiatry, Psychology & Neuroscience at King's College London. The research, published today in Scientific Reports, also suggests that educational achievement at GCSE is highly heritable, with over half of the difference between results potentially due to inherited differences in DNA. Previous studies have shown that academic achievement in the core subjects of English, mathematics and science at GCSE may be influenced by the same genetic traits. ...

New insights into the circuitry of PTSD and mild traumatic brain injury

2015-07-23
Philadelphia, PA, July 23, 2015 - Posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) can have devastating consequences. Both are associated with high rates of disability and suicide, and although they are separate conditions, they commonly co-occur. For example, a soldier who has developed PTSD as a result of a traumatic experience may have also sustained a brain injury during that experience. Significant research has been conducted to understand the brain mechanisms underlying PTSD and TBI, but there has still been a lack of knowledge regarding exactly ...
