NOTE TO READERS: When this project lost substantial funding at the end of 2018, I lost the ability to continue publishing criteria-driven news story reviews and PR news release reviews - once the bread-and-butter of the site going back to 2006. The 3,200 archived reviews, while still educational, are getting old and difficult for me to technically maintain on the back end of the website. So I am announcing that I plan to remove these reviews from the site by April 1, 2021. The blog and the toolkit - two of the most popular features on the site - will remain. If you wish to peruse the reviews before they disappear, please do so by the end of March 2021. After that date you may still be able to access them via the Internet Archive Wayback Machine - https://archive.org/web/.

Debate over who needs a thyroid check in pregnancy

Our Review Summary

The article gives extensive context to the recent Journal of Clinical Endocrinology & Metabolism study and refers to other research done in the field.

 

Why This Matters

The article effectively breaks down and explains a complex debate in the physician community – whether all pregnant women should be screened for thyroid function and whether women with milder cases of hypothyroidism should be diagnosed and treated. The story says this will “add pressure” for science to settle this issue, but that pressure already exists from endocrinologists and obstetricians – with, as the study shows, about 1 in 5 pregnant women being tested from 2005-8.

 

Criteria

Does the story adequately discuss the costs of the intervention?

Satisfactory

The story states that a $25 blood test can identify someone with a thyroid disorder. The costs associated with daily hormone therapy are not discussed.

Does the story adequately quantify the benefits of the treatment/test/product/procedure?

Satisfactory

The article does an excellent job explaining the importance of thyroid hormones during pregnancy for fetal brain development, especially during the first trimester. It also points out the role in preventing miscarriage and premature birth. Furthermore, the story thoroughly details the risks that come with an overactive or an underactive thyroid gland for the average person.

Does the story adequately explain/quantify the harms of the intervention?

Satisfactory

The article mentions that, for mild cases of hypothyroidism, scientists are unsure whether diagnoses and subsequent treatment sufficiently help pregnant patients or, instead, waste money on blood testing and thyroid medication. This is appropriately stated high up (in the first third) in the report.

Does the story seem to grasp the quality of the evidence?

Satisfactory

The article briefly mentions that the Quest Diagnostics study looked at records and surveys from half a million pregnant women, but apart from this fact, the story does not outline any more research methods or protocol. We could interpret the findings better if we knew, for example:

  • how do the women who were tested at Quest reflect the general population of pregnant women?
  • how did changes in the definition of what is abnormal affect the results, compared to older studies?

Does the story commit disease-mongering?

Satisfactory

There is no disease mongering in this story. The article gives appropriate and sufficient background information on various thyroid disorders and how they could affect pregnant women.

Does the story use independent sources and identify conflicts of interest?

Satisfactory

The comment from Dr. Dena Goffman of New York’s Montefiore Medical Center offers an outside perspective on the research and the “long-running controversy” regarding thyroid testing for pregnant women. However, researchers at Quest Diagnostics – one of the world’s biggest companies for diagnostic services – conducted this study, which found a “higher-than-expected” number of pregnant women with underactive thyroids. Whether Quest Diagnostics funded the study, or whether Dr. Elizabeth Pearce had ties to the company, were not explicitly discussed.

Does the story compare the new approach with existing alternatives?

Satisfactory

The story offers different perspectives and guidelines on thyroid screening from the American College of Obstetricians and Gynecologists and the American Thyroid Association.

Does the story establish the availability of the treatment/test/product/procedure?

Satisfactory

The story makes it clear that “nearly a quarter of pregnant women are getting the simple thyroid blood test regardless of whether they have symptoms.”

Does the story establish the true novelty of the approach?

Satisfactory

Thyroid function screening via a blood test is not a new concept. The question is whether milder cases of hypothyroidism in pregnant women should be treated with daily hormone therapy. In general, the article does an excellent job laying out both sides of the issue.

Does the story appear to rely solely or largely on a news release?

Satisfactory

There was no evidence that the story relied solely on a press release.

Total Score: 10 of 10 Satisfactory
