Background: The news media are often criticized for exaggerated coverage of weak science. Press releases, a source of information for many journalists, might be a source of those exaggerations. Objective: To characterize research press releases from academic medical centers. Design: Content analysis. Setting: Press releases from 10 medical centers at each extreme of U. S. News & World Report's rankings for medical research. Measurements: Press release quality. Results: Academic medical centers issued a mean of 49 press releases annually. Among 200 randomly selected releases analyzed in detail, 87 (44%) promoted animal or laboratory research, of which 64 (74%) explicitly claimed relevance to human health. Among 95 releases about primary human research, 22 (23%) omitted study size and 32 (34%) failed to quantify results. Among all 113 releases about human research, few (17%) promoted studies with the strongest designs (randomized trials or meta-analyses). Forty percent reported on the most limited human studies-those with uncontrolled interventions, small samples (<30 participants), surrogate primary outcomes, or unpublished data-yet 58% lacked the relevant cautions. Limitation: The effects of press release quality on media coverage were not directly assessed. Conclusion: Press releases from academic medical centers often promote research that has uncertain relevance to human health and do not provide key facts or acknowledge important limitations.
