Johnson addressed journalists in any medium; I focused only on television reporters who cover health and medicine. Now 13 years after I first raised the idea, I’m raising it again. In many television markets across the country, the quality of health news and information has plummeted to a level that makes watching many TV health stories an unhealthy activity. In my own research, I have described ten troublesome trends in television health news. They are: brevity (average story length of 45 seconds); absence of reporter specialization; sensational claims not supported by data; hyperbole; commercialism; disregard for the uncertainty of clinical trials; baseless basic science predictions; single-source stories; a paucity of coverage of health policy; and little, if any, enterprise journalism.

Corrections for most of these troubles are within reach — with a little time and training. But the truth is the meteorological lobby may be stronger than the forces calling for improved health journalism. Texas State Rep. Vicki Truitt introduced a bill this year which would have made it a misdemeanor for people who give weather forecasts on television to call themselves “meteorologists” unless they have completed more than 40 hours of college-level study in several subjects, including atmospheric science, physics and ordinary differential equations. “I think the general public just assumes that if someone on the evening weather says, ‘I am a meteorologist,’ we assume they’re formally trained,” Truitt said in an article in the Fort Worth Star-Telegram. “Yet there’s no specific requirement that they must be. I got to thinking of it from a public-safety perspective, and if someone says they’re something that they’re not, and given the weather in this state, that could potentially create a dangerous situation.”

She decided to withdraw the bill after meeting with three Texas television news staffers, but in the meantime the American Meteorological Society is toughening its certification standards, creating a new “Certified Broadcast Meteorologist” category. To be certified, a meteorologist must accumulate a number of “professional development” points over a five-year period. Points are given in 25 categories, including for attendance at certain workshops and completing related undergraduate or graduate-level courses.

I just completed two terms on the board of the Association of Health Care Journalists (AHCJ), a six-year-old organization with more than 850 members. Perhaps AHCJ could be the certifying body for broadcast health journalists. I’m going to promote the idea within AHCJ, but I expect opposition. The idea of certifying journalists may send up red flags if it’s viewed as an attempt to control journalists. It is not that. It is merely an attempt to certify for viewers that the journalist cared enough to learn more about coverage of vital health issues. Maybe those seeking certification would improve their reporting. Maybe it could prevent some of the shameless sensationalism and waste of airtime that occurs in empty, meaningless reports of health news.

Those seeking certification could attend workshops or use online training modules to learn about how relatively meaningless it can be to cite relative (rather than absolute) risks; about the Food and Drug Administration approval process; and about how to scrutinize claims and evaluate the quality of evidence presented by sources. Workshops on health journalism ethics would address the trend toward commercialism that has seen television journalists reporting on their own heart scans, on their own Lasik surgery, and on wrinkle-removing products, usually with no discussion of the evidence supporting the effectiveness of these new ideas, nor the costs associated with them. Those who are new to the health beat would benefit simply by studying the Association of Health Care Journalists’ statement of principles.

Quality and reliability should be greater concerns in health news than in weather forecasts. Surveys consistently show that many Americans get most of their health news and information from television, yet, according to a 2002 Gallup Poll, television is the least trusted source of such information.

In his NEJM article, Dr. Tim Johnson wrote: “If we think it is important to certify hairdressers and massage therapists, might not it be important to certify those who transmit medical news day in and day out? As Mark Twain reportedly put it, ‘Be careful about reading health books; you may die of a misprint,’ or, I might add, of a mistake.”

Certification wouldn’t eliminate misprints or mistakes. But what journalists learn in the certification process would help them do a better job, and would help protect viewers as they try to separate the pros from the puppets.
