(Press-News.org) PITTSBURGH— Despite heightened awareness about the undue influence that gifts from pharmaceutical companies can have on doctors' prescribing practices, and despite expanding institutional conflict-of-interest policies and state laws targeted at preventing such practices, companies continue to reward doctors for prescribing their drugs with gifts ranging from pens and paper, to free dinners and trips. A new study by two researchers at Carnegie Mellon University, published in the Journal of the American Medical Association, helps to explain how doctors rationalize acceptance of such gifts, which author George Loewenstein, the Herbert A. Simon Professor of Economics and Psychology, describes as "barely described bribes." The study found that physicians rationalize acceptance of these gifts as a form of reward for the sacrifices they made obtaining their education.
Three hundred and one pediatric and family medicine residents answered a series of questions that asked about the acceptability of receiving different types of gifts from pharmaceutical companies. Before completing the survey, however, one group of doctors were first asked about the sacrifices they had made in getting their medical education. A second group were also first asked these sacrifice questions and then were asked whether such sacrifices could potentially justify acceptance of gifts (a rationalization that explicitly introduces the idea that this might be the case) before filling out the gift acceptability questions. A control group was asked about the acceptability of receiving gifts without being first asked about personal sacrifices or being cued with a potential rationalization.
Reminding physicians first of their medical training burdens more than doubled their willingness to accept gifts — from 21.7 percent to 47.5 percent, and suggesting the potential rationalization further increased their willingness to accept the gifts -- to 60.3 percent. The impact of the suggested rationalization was surprising because, when asked whether their hardships justified taking gifts, most respondents said it did not. Sunita Sah, the study's lead author and a physician herself who is completing her PhD at Carnegie Mellon's Tepper School of Business, commented that "this finding suggests that even justifications that people don't accept at a conscious level can nonetheless help them to rationalize behavior that they otherwise might find unacceptable."
Both authors agree that the implications of the study are straightforward. "Given how easy it is for doctors to rationalize accepting gifts, which, from other research, we know influences their prescribing behavior, the inescapable conclusion is that gifts should simply be prohibited," said Loewenstein, who has done extensive research and writing on the role of human psychology in exacerbating conflicts of interest.
"Given the powerful human capacity to rationalize what benefits us," Sah added, "it is unlikely that we will be able to make a dent in the problem by, for example, educating physicians about the risks posed by conflicts."

Medical students report critical attitudes about depression among peers, U-M study shows
2010-09-15
Ann Arbor, Mich. --- Medical students experience depression at a higher rate than the general population and attach high levels of stigma to the mental illness, according to U-M research to be published Sept. 15 in the Journal of the American Medical Association.
The study showed that 53.3 percent of medical students who reported high levels of depressive symptoms were worried that revealing their illness would be risky. Almost 62 percent of the same students said asking for help would mean the student's coping skills were inadequate.
Those with moderate to severe ...
Diversity or deprivation -- what makes a 'bad' neighborhood
2010-09-15
"People's views of their neighbourhood can influence major decisions such as moving house and choice of school. A neighbourhood can also acquire a reputation as a 'good' or 'bad' area. It is therefore important to understand what these views are based on," says Dr Liz Twigg, University of Portsmouth, who led the research.
"Previous research has suggested that diverse communities are less cohesive and suffer from problems associated with anti-social behaviour, crime and lack of trust," she explains. "Our research suggests that this is not true. In general, what people ...
Neuroimaging identifies patients with REM sleep disturbances who will suffer Parkinson's disease
2010-09-15
REM sleep disturbances constitute an early marker of neurodegenerative diseases. This was demonstrated by the Multidisciplinary Sleep Disturbances Unit of the Hospital Clínic, in an article published in 2006. A new study published by the same team in Lancet Neurology applies neuroimaging techniques to identify patients with REM sleep disturbances who will develop neurodegenerative disorders over the short term. The first signing author of both papers is Dr. Àlex Iranzo, a physician belonging to the Neurology Department of the Hospital Clínic in Barcelona, who is also an ...
New treatment for rabies advances after successful phase 1 trial in India
2010-09-15
BOSTON, Mass.—With the potential to save tens of thousands of lives each year, a new cost-effective rabies therapy developed by MassBiologics at the University of Massachusetts and the Serum Institute of India took an important step forward with positive results from a Phase 1 study. The recently completed study showed that a new monoclonal antibody (RAB-1) resulted in protective antibody levels in the serum of treated subjects equal to the current standard of treatment, which is often not available in the areas of the world hit hardest by rabies.

JAMA commentary calls for incorporating economic reality into medical education
2010-09-15
Medical students and residents should receive much more thorough and realistic instruction about the economic forces affecting health care and their own clinical decisions so that they can better serve patients' well-being and the nation's economic welfare, says a commentary published today in a theme issue of the Journal of the American Medical Association (JAMA), which focuses on improving medical education.
The commentary is written by Samuel Y. Sessions, MD, JD, a Los Angeles Biomedical Research Institute (LA BioMed) investigator, and Allan S. Detsky, MD, PhD, Departments ...
No support for routine prostate screening, but one-off test at 60 may be beneficial
2010-09-15
Existing evidence from randomised controlled trials does not support routine population screening for prostate cancer, concludes a study published on bmj.com today.
However, a second study also published today suggests that a single test at age 60 could identify men who are most likely to develop and die from prostate cancer. These men could then be monitored more closely, while others could be exempt from further screening.
Prostate cancer is one of the most common cancers among men worldwide. Screening is widely used in many countries, but it remains controversial ...

Washington, DC, (September 14, 2010) — A new study released today by the American Lung Association, and conducted by researchers at Penn State University, finds that helping smokers quit not only saves lives but also offers favorable economic benefits to states. The study, titled Smoking Cessation: the Economic Benefits, provides a nationwide cost-benefit analysis that compares the costs to society of smoking with the economic benefits of states providing cessation (quit-smoking) coverage. The study comes at an important time, as important cessation benefit provisions ...
Outsmarting killer bacteria
2010-09-15
Antibiotics can work miracles, knocking out common infections like bronchitis and tonsillitis. But according to the Center for Disease Control, each year 90,000 people in the U.S. die of drug-resistant "superbugs" ― bacteria like Staphylococcus aureus (MRSA), a deadly form of staph infection resistant to normal antibiotics. Although hospital patients are particularly susceptible as a result of open wounds and weakened immune systems, the bacteria can infect anyone.
Dr. Micha Fridman of Tel Aviv University's Department of Chemistry is now developing the next generation ...
Last strongholds for tigers identified in new study
2010-09-15
NEW YORK (Embargoed until September 14, 2010: 5:00 p.m. U.S. Eastern Time)— A new peer-reviewed paper by the Wildlife Conservation Society and other groups reveals an ominous finding: most of the world's last remaining tigers—long decimated by overhunting, logging, and wildlife trade—are now clustered in just six percent of their available habitat. The paper identifies 42 'source sites' scattered across Asia that are now the last hope and greatest priority for the conservation and recovery of the world's largest cat.
The securing of the tiger's remaining source sites ...
