Findings
Televised medical talk shows—what theyrecommend and the evidence to support their recommendations: a prospective observational study
Strengths:
❏ Random selection of a number of episodes of The Dr. Oz Show and The Doctors.
❏ Multiple independent coders assessing recommendations provided by the shows.
❏ Expert review of the scientific literature to find evidence for the proposed advice.
Conclusion:
❏ “Approximately half of the recommendations have either no evidence or are contradicted by the best available evidence. Potential conflicts of interest are rarely addressed.”
Reality check: no such thing as a miracle foodStrengths:
❏ Cited peer-reviewed scientific studies.
❏ Specifically investigated a claim made on The Dr. Oz Show.
Limitations:
❏ Search strategy was not included.
Conclusion:
❏ There is not enough evidence to support the promotion of the foods as preventing cancer.
❏ “Many types of studies are needed to evaluate the impact of diet in cancer prevention.” (Inoue-Choi et al., 2014).
Why Dr. Oz Makes Us Crazy
Strengths:
❏ Recommendation seems logical and useful.
Limitations:
❏ Physician commentary.
Conclusion:
❏ Criticized The Dr. Oz Show for attempting to provide population-level medical advice for health problems that require individualized attention.
❏ Medical professionals should clearly state limitations when providing advice to an audience.
❏ Dr. Oz uses successful techniques to educate patients, which could be beneficial to doctors.
The Oz craze: The effect of pop culture media on health careStrengths:
❏ Data on internet search and product purchase behaviors in relation to the airing of associated topics on The Dr. Oz Show.
Limitations:
❏ Stronger evidence such as surveys of show viewers would be necessary to determine a causal relationship.
Conclusion:
❏ Raises concern about the potential for patient harm due to Dr. Oz’s (as well as other celebrities) unsupported advice.
❏ Presents the need for objective research to measure the influence popular media and celebrities have on viewers’ health behaviors.

Following celebrities’ medical advice: meta-narrative analysisStrengths:
❏ Synthesis of information across several disciplines.
❏ Prioritization of empirical evidence and established theories.
Limitations:
❏ Narrative analyses often are not viewed as strong or generalizable evidence.
❏ A causal connection for celebrities’ influence on health behaviors is missing.
Conclusion:
❏ Celebrities are seen as credible, trustworthy, and desirable when offering medical or health advice, no matter their credentials or the available evidence.
❏ Celebrities should be required to disclose conflicts of interest to help consumers decipher actual (versus perceived) credibility.
❏ Harness the power of celebrity to promote evidence-based health behaviors.
“Following actor-singer Kylie Minogue’s diagnosis of breast cancer, bookings for mammograms rose by 40%
in four Australian states.2 Twice as many screenings for cervical cancer were conducted in England during March 2009 compared with the same month one year earlier, corresponding to reality TV star Jade Goody’s
death from the disease.3” (Hoffman & Tan, 2013)
ConclusionThere is not enough evidence to verify that incorrect information provided by mainstream media
physicians results in patient harm, however, the current
evidence is sufficient to warrant preventive action.
❏ More research needed.
❏ Policies to promote or disclose the level
of credibility of health information
presented in the media need to be
enacted as a protective measure for
consumers.
❏ Opportunity to form stronger
relationships between popular television
shows and health professionals to
disseminate accurate health information
in an entertaining way.
❏ Media literacy and health literacy
education are a necessary component
and should be added to school curriculum
at all levels.
