A study published in the New England Journal of Medicine describes the frequency of utilization of imaging tests in the United States and the associated radiation exposure. Researchers found that a staggering nearly 70% of adults in the study population got an imaging test over the two years of the study. These results highlight the potential harms of such a high use of imaging, which is not limited to radiation exposure, but also includes the potential for diagnosing conditions which would never go on to cause a problem, leading to unnecessary treatments, not to mention stress and anxiety.
This story adequately describes the current study and its implications in terms of radiation exposure. But it also focuses primarily on the economic implication of such high utilization. Given the current debate on healthcare reform, this awareness is important, however it is peripheral to the study under discussion. The study was really focused on quantifying how much imaging tests expose us to radiation, not on the high costs of these tests and the market forces behind the high utilization. Regardless, this story does remind us that as consumers we need to be aware of these market forces and confident that when tests are ordered, we are aware of the implications for own health, both good and bad.
It would not be neccessary for the story to describe the costs of individual radiology tests since they are so varied. But the story does a good job of describing the overall toll of imaging costs and raises important points about the perverse financial incentives in the US healthcare economy which favors the ordering of more and more tests.
The story suggests in an early quote from one of the study authors that the newer tests are "…extremely helpful…" but then notes that there is insufficient information to determine which tests are valuable and which ones are not.
The story does a good job of describing the possible harms of imaging, including radiation exposure, overdiagnosis and pyschological distress.
The story provides an adequate overview of the study under consideration. However much of the story is about the costs and potential overutilization of diagnostic testing. While appealing and timely, the story does not provide adequate evidence to support many of the comments related to these issues.
The story pursues a theme that the tests are doing more harm than good – quite in contrast to a disease-mongering frame that might suggest that all imaging is necessary.
The story quotes multiple sources.
Clearly the alternative is no testing, particularly in the context of management of chronic diseases. The story could have described how traditional hands-on examinations and history-taking are alternatives to testing.
Clearly radiology tests are widely available.
Clearly imaging is not a new idea, but it is being used on an increasingly larger scale.
Because the story quotes multiple sources, the reader can assume that the story does not rely on a press release as the sole source of information.

Monday at #ADA2021, an infectious disease epidemiologist, a journalist, and a researcher shared perspectives on communication of risk in the era of COVID-19: http://ow.ly/ROfR30rMeE7 @AstleyCM @garyschwitzer @berthahidalgo @ADA_DiabetesPro
Shoutouts to @susan_bewley @drkevinknopf @MichaelBaum11 in this call for more than fawning coverage from press releases for these kinds of stories.
Also, linked history inside goes back 5 years just on Grail apparently trying to become Holy Grail. https://twitter.com/garyschwitzer/status/1408849696416841731
