Have screening harms become newsworthy? News coverage of prostate and colorectal cancer screening since the 2008 USPSTF recommendation changes

News Coverage of Colorectal Cancer on Google News: Descriptive Study

Background

Colorectal cancer (CRC) is one of the leading causes of cancer death in the United States. The incidence and prevalence of CRC have historically increased with age. Although rates of CRC in the United States have been decreasing over the past decades among those aged ≥65 years, there has been an uptick among those in younger age brackets. Google News is one of the biggest traffic drivers to top news sites. It aggregates and shares news highlights from multiple sources worldwide and organizes them by content type. Despite the widespread use of Google News, research is lacking on the type of CRC content represented in this news source. 

Objective

The purpose of this study was to analyze content related to CRC screening and prevention in Google News articles published during National Colorectal Cancer Awareness Month (March 2022).

Methods

Data collection for this cross-sectional study was conducted in March 2022—National Colorectal Cancer Awareness Month. Using the term colorectal cancer, 100 English-language Google News articles were extracted and coded for content. A combined approach—deductive and inductive coding—was utilized. Descriptive analyses were conducted, and frequency distributions were reported. Univariable analyses were performed to assess differences between articles that mentioned CRC screening and those that did not via chi-square tests.

Results

Of the 100 articles reviewed, nearly half (n=49, 49%) were created by health news organizations, and another 27% (n=27) were created by television news services. The predominant themes in the content included age at the onset of disease (n=59, 59%), mortality related to CRC (n=57, 57%), and the severity of disease (n=50, 50%). Only 18% (n=18) of articles discussed CRC disparities, 23% (n=23) mentioned that there are hereditary forms of the disease, 36% (n=36) spoke of colonoscopy to screen for the disease, and 37% (n=37) mentioned how the disease is treated. Although most articles mentioned CRC screening (n=61, 61%), it was striking that sex was only mentioned in 34% (21/61) of these articles, colonoscopy was mentioned in 46% (28/61), and diet was mentioned in 30% (18/61).

Conclusions

Heightening the public’s awareness of this disease is important, but it is critical that messages related to how preventable this cancer is, who is the most likely to develop CRC, and what can be done to detect it in the early stages when the disease is the most curable be the critical elements of dialogue, particularly during National Colorectal Cancer Awareness Month. There is a need to disseminate information about early-onset CRC and the importance of screening, especially among populations with low rates of uptake. Web-based news is potentially an underutilized communication mechanism for promoting CRC screenings as secondary prevention measures for high-risk groups.

Predictors of Women's Awareness of the Benefits and Harms of Mammography Screening and Associations with Confusion, Ambivalence, and Information Seeking

In recent years, there has been a shift toward promoting informed decision making for mammography screening for average-risk women in their 40s. Professional organizations such as the American Cancer Society and U.S. Preventive Services Task Force recommend that women weigh the potential benefits and harms of mammography prior to initiating screening. This decision-making process assumes that women are aware of both the benefits and harms of screening, yet little is known about the prevalence and antecedents of such awareness. Moreover, it is conceivable that women who are aware of both the benefits and harms may interpret this information as conflicting - which could be concerning, as researchers have documented adverse effects of exposure to conflicting health information in prior research. Using data from a population-based survey of U.S. women aged 30-59 (N = 557), the current study found that awareness of mammography's harms is relatively low compared to awareness of benefits. Health news exposure and interpersonal communication about health were associated with greater awareness of harms. In addition, women's awareness of both the benefits and harms was positively associated with confusion about breast cancer screening recommendations, ambivalence about getting a mammogram, and mammogram-related information seeking from online sources. Implications for cancer screening communication are discussed.

30+ years of media analysis of relevance to chronic disease: a scoping review

BACKGROUND

Chronic, non-communicable diseases are a significant public health priority, requiring action at individual, community and population levels, and public and political will for such action. Exposure to media, including news, entertainment, and advertising media, is likely to influence both individual behaviours, and attitudes towards preventive actions at the population level. In recent years there has been a proliferation of research exploring how chronic diseases and their risk factors are portrayed across various forms of media. This scoping review aims to map the literature in this area to identify key themes, gaps, and opportunities for future research in this area.

METHODS

We searched three databases (Medline, PsycINFO and Global Health) in July 2016 and identified 499 original research articles meeting inclusion criteria: original research article, published in English, focusing on media representations of chronic disease (including how issues are framed in media, impact or effect of media representations, and factors that influence media representations). We extracted key data from included articles and examined the health topics, media channels and methods of included studies, and synthesised key themes across studies.

RESULTS

Our findings show that research on media portrayals of chronic disease increased substantially between 1985 and 2016. Smoking and nutrition were the most frequent health topics, and television and print were the most common forms of media examined, although, as expected, research on online and social media channels has increased in recent years. The majority of studies focused on the amount and type of media coverage, including how issues are framed, typically using content analysis approaches. In comparison, there was much less research on the influences on and consequences of media coverage related to chronic disease, suggesting an important direction for future work.

CONCLUSIONS

The results highlight key themes across media research of relevance to chronic disease. More in-depth syntheses of studies within the identified themes will allow us to draw out the key patterns and learnings across the literature.

The Evolution of Mammography Controversy in the News Media: A Content Analysis of Four Publicized Screening Recommendations, 2009 to 2016

BACKGROUND

There is longstanding expert disagreement about the age at and frequency with which women should be screened for breast cancer. These debates are reflected in the conflicting recommendations about mammography issued by major professional organizations, such as the U.S. Preventive Services Task Force and the American Cancer Society. Previous research has shown that these recommendations garner substantial media attention-and therefore might affect women's screening perceptions and behaviors-but to date analyses of such media coverage have focused on single publicized announcements.

METHODS

To assess whether media coverage of mammography screening recommendations has evolved, we conducted a content analysis of televised news from four discrete media events from 2009 to 2016, all of which focused on publicized screening recommendations from the U.S. Preventive Services Task Force and American Cancer Society (N = 364 stories).

RESULTS

Media coverage of mammography screening recommendations has featured persistent messages of conflict and/or controversy over time. The evolution of controversy was also reflected in shifts in the relative attention given to mammography screening's risks and benefits, with consistent and, in some cases, heightened attention to screening's risks during more recent media events. Overall, the accuracy of media coverage improved over time.

CONCLUSIONS

Results underscore the continued prevalence of conflicting and/or controversial information about mammography screening in the public information environment. Cumulative exposure to such messages could influence women's decision making around screening and trust in cancer prevention recommendations. Strategies are needed to better equip all women (and particularly underserved women) to negotiate mammography controversy and weigh the benefits and risks of screening.

One Step Forward, One Step Back: Changes in News Coverage of Medical Interventions

During 2005-2013, the award-winning website HealthNewsReview.org offered reviews of major media outlets' news stories related to health interventions, including tests, treatments, dietary changes, and prescription drugs. The reviews offered a measure by which the public and journalists themselves could assess the completeness and usefulness of health coverage across 10 criteria for quality reporting. This study produced an analysis of those reviews from 2005 to 2013, indicating significant changes in key areas. Analysis of 1,889 health news story reviews published by HealthNewsReview.org (HNR) between 2005 and 2013 showed that, on average, the stories reviewed during 2005-2010 successfully met just less than half of the criteria, but by 2010-2013, that average had improved to almost 70%. There were significant improvements over time in news organizations' success in meeting six of HNR's 10 criteria for a successful health news story related to drugs, devices, surgery and other medical procedures, and diet; however, when data for television stories were excluded, only the improvement in avoiding disease-mongering remained significant. In addition, there was a statistically significant decline in the percentage of stories rated satisfactory on establishing the true novelty of the intervention discussed in the story. There was no improvement in quantification of possible harms from medical interventions. Changes over time in meeting the criteria were related to outlet type and story topic.

Women's Awareness of and Responses to Messages About Breast Cancer Overdiagnosis and Overtreatment: Results From a 2016 National Survey

BACKGROUND

Scientists, clinicians, and other experts aim to maximize the benefits of cancer screening while minimizing its harms. Chief among these harms are overdiagnosis and overtreatment. Although available data suggest that patient awareness of these harms is low, we know little about how patients respond to information about these phenomena.

OBJECTIVES

Using the case of breast cancer screening, this study assesses women's awareness of and reactions to statements about overdiagnosis and overtreatment.

METHODS

We draw on data from a 2016 population-based survey of US women aged 35-55 years that oversampled women of lower socioeconomic position (those living at or below 100% of federal poverty level) (N=429).

RESULTS

Results showed that women's awareness of overdiagnosis (16.5%) and overtreatment (18.0%) was low, and women under age 40 were least likely to have heard about overdiagnosis. Most women did not evaluate statements about these harms positively: <1 in 4 agreed with and found statements about overdiagnosis and overtreatment to be believable, and even fewer evaluated them as strong arguments to consider in their own mammography decision making. Women with a recent mammogram history were particularly unconvinced by overdiagnosis and overtreatment arguments.

CONCLUSIONS

A majority of women were unaware of 2 important harms of breast cancer screening: overdiagnosis and overtreatment. Most did not find statements about these harms to be believable and persuasive. Communication interventions, supported by evidence from health communication research, are necessary to improve patient understanding of screening's harms, promote informed decision making, and, in turn, ensure high-value care.

Testing and referral patterns in the years surrounding the US Preventive Services Task Force recommendation against prostate-specific antigen screening

BACKGROUND

Since the US Preventive Services Task Force (USPSTF) recommended against prostate-specific antigen (PSA) screening, there have been conflicting reports regarding the impact on the behavior of providers. This study analyzed real-world data on PSA ordering and referral practices in the years surrounding the recommendation.

METHODS

A whole-institution sample of entered PSA orders and urology referrals was obtained from the electronic medical record. The study was performed at a tertiary referral center with a catchment in the southern United States. PSA examinations were defined as screening when they were ordered by providers with appointments in internal medicine, family medicine, or general internal medicine. Linear and quadratic regression analyses were performed, and joinpoint regression was used to assess for trend inflection points.

RESULTS

Between January 2010 and July 2015, there were 275,784 unique ambulatory visits for men. There were 63,722 raw PSA orders, and 54,684 were evaluable. Primary care providers ordered 17,315 PSA tests and 858 urology referrals. The number of PSA tests per ambulatory visit, the number of referrals per ambulatory visit, the age at the time of the urology referral, and the proportion of PSA tests performed outside the recommended age range did not significantly change. The PSA value at the time of referral increased significantly (P = .022). Joinpoint analysis revealed no joinpoints in the analysis of total PSA orders, screening PSA tests, or examinations per 100 visits.

CONCLUSIONS

In the years surrounding the USPSTF recommendation, PSA behavior did not change significantly. Patients were referred at progressively higher average PSA levels. The implications for prostate cancer outcomes from these trends warrant further research into provider variables associated with actual PSA utilization.

Clinicians' perceptions of the benefits and harms of prostate and colorectal cancer screening

BACKGROUND

Clinicians' perceptions of screening benefits and harms influence their recommendations, which in turn shape patients' screening decisions. We sought to understand clinicians' perceptions of the benefits and harms of cancer screening by comparing 2 screening tests that differ in their balance of potential benefits to harms: colonoscopy, which results in net benefit for many adults, and prostate-specific antigen (PSA) testing, which may do more harm than good.

METHODS

In this cross-sectional study, 126 clinicians at 24 family/internal medicine practices completed surveys in which they listed and rated the magnitude of colonoscopy and PSA testing benefits and harms for a hypothetical 70-year-old male patient and then estimated the likelihood that these tests would cause harm and lengthen the life of 100 similar men in the next 10 years. We tested the hypothesis that the availability heuristic would explain the association of screening test to perceived likelihood of benefit/harm and a competing hypothesis that clinicians' gist of screening tests as good or bad would mediate this association.

RESULTS

Clinicians perceived PSA testing to have a greater likelihood of harm and a lower likelihood of lengthening life relative to colonoscopy. Consistent with our gist hypothesis, these associations were mediated by clinicians' gist of screening (balance of perceived benefits to perceived harms).

LIMITATIONS

Generalizability beyond academic clinicians remains to be established.

CONCLUSIONS

Targeting clinicians' gist of screening, for example through graphical displays that allow clinicians to make gist-based relative magnitude comparisons, may influence their risk perception and possibly reduce overrecommendation of screening.
