MedicalResearch.com: What is the background for this study?
Response: Minimizing care that provides little benefit to patients has become an important focus to decrease health care costs and improve the quality of care delivery. Diagnostic imaging in children is a common focus for campaigns designed to reduce overuse both in Canada and the US. There are some suggestions that there may be more overuse of care in the United States than Canada, but there has been little study in children.
We compared the use of low-value diagnostic imaging rates from four pediatric emergency departments in Ontario to 26 in the United States from 2006 to 2016. We defined low-value imaging as situations where children are discharged from an emergency department with a diagnosis for which routine use of diagnostic imaging may not be necessary, like asthma or constipation.

MedicalResearch.com: What is the background for this study?
Response: There is some mixed evidence regarding whether state level tort reform reduces defensive medicine, or the practicing of medicine in such a way to reduce medical liability. This includes “positive” defensive medicine, or performing certain tests and procedures to reduce such liability. Other research finds that the perception of malpractice risk drives such defensive medicine, including the use of diagnostic imaging, such as CT scans and MRIs.
I was interested in exploring what influenced the perception of this risk, hypothesizing that, for a physician, a report of an injury against one’s colleague might increase the perception of this risk and lead to an increase the use of diagnostic imaging.

MedicalResearch.com: What is the background for this study?
Response: There are two peanut allergy treatments that are being evaluated for potential FDA approval—an orally administered treatment and an epicutaneous (skin based) treatment. Both have tremendous potential benefit. The focus of our study was to explore the range of health and economic benefits in terms of establishing pathways for how each therapy could be cost effective.
We want to be clear that our purpose was not to suggest one therapy is or is not cost effective at present. That would be a ridiculous statement to make regarding two treatments that not only lack FDA approval, but do not have established pricing. Rather, we used preliminary inputs that are presently available to create as robust a model as we could to better determine the individual paths that would make them more or less cost-effective.
