Predictors of perceived breast cancer risk and the relation between perceived risk and breast cancer screening: a meta-analytic review

Do Health Information Exchanges Deter Repetition of Medical Services?

Repetition of medical services by providers is one of the major sources of healthcare costs. The lack of access to previous medical information on a patient at the point of care often leads a physician to perform medical procedures that have already been done. Multiple healthcare initiatives and legislation at both the federal and state levels have mandated Health Information Exchange (HIE) systems to address this problem. This study aims to assess the extent to which HIE could reduce these repetitions, using data from Centers for Medicare 8 Medicaid Services and a regional HIE organization. A 2-Stage Least Square model is developed to predict the impact of HIE on repetitions of two classes of procedures: diagnostic and therapeutic. The first stage is a predictive analytic model that estimates the duration of tenure of each HIE member-practice. Based on these estimates, the second stage predicts the effect of providers’ HIE tenure on their repetition of medical services. The model incorporates moderating effects of a federal quality assurance program and the complexity of medical procedures with a set of control variables. Our analyses show that a practice's tenure with HIE significantly lowers the repetition of therapeutic medical procedures, while diagnostic procedures are not impacted. The medical reasons for the effects observed in each class of procedures are discussed. The results will inform healthcare policymakers and provide insights on the business models of HIE platforms.

Discordance in perceived risk and epidemiological outcomes of prostate cancer among African American men

As guidelines for prostate cancer screening have changed from an annual screening recommendation starting at age 50 to discussing the benefits and harms of screening with health care providers, it is necessary to examine other types of factors that are important to prostate cancer screening decisions among African American men. Perceived risk of developing cancer has been shown to predict cancer control behaviors and is lower among African Americans. We characterized perceived risk of developing prostate cancer among African American men from November 2009 to 2011 and evaluated the relationship between prostate cancer risk perceptions and sociodemographic characteristics, health care experiences, and knowledge and exposure to health information about cancer. Chi square tests and logistic regression were employed to determine independent associations. Overall, men did not believe they were at increased risk of developing prostate cancer; they believed their risk was equivalent to or lower than men the same age. Perceived risk of prostate cancer was associated with income (OR = 0.59, 95% CI = 0.26, 1.34, p = 0.03), hypertension (OR = 2.68, 95% CI = 1.17, 6.16, p = 0.02), and beliefs about the association between race and cancer risk (OR = 2.54, 95% CI = 1.24, 5.20, p = 0.01). Clinic and community-based approaches to improve prostate cancer risk comprehension among African American men are needed to reduce the discordance between perceived risk and epidemiological data on prostate cancer risk factors. Risk education interventions that are developed for African American men may need to integrate information about susceptibility for multiple diseases as well as address strategies for risk reduction and prevention, and chronic disease management.

Knowledge and perception of cardiovascular disease risk among patients with rheumatoid arthritis

Patients with rheumatoid arthritis are at increased risk for cardiovascular disease. The prerequisites for reducing the risk of cardiovascular disease are adequate levels of knowledge and being aware of the risk. In this study, the levels of knowledge about cardiovascular disease among patients with rheumatoid arthritis and the perception were evaluated in relation to their actual 10-year risk of cardiovascular disease. This cross-sectional study of 200 patients with rheumatoid arthritis was conducted in a university-affiliated hospital in South Korea. The patients' actual risk of cardiovascular disease was estimated using the Framingham Risk Score. The most common risk factor was physical inactivity, with 77% of the patients not engaging in regular exercise. The patients lacked knowledge about the effects of physical inactivity and anti-inflammatory medication on the development of cardiovascular disease. Misperceptions about the risk of cardiovascular disease were common, i.e., 19.5% of the patients underestimated their risk and 41% overestimated. Hypertension, diabetes, obesity, and smoking were the most prevalent among the patients who underestimated their risk, and these same patients had the lowest level of knowledge about cardiovascular disease. This study demonstrated the rheumatoid arthritis patients' lack of knowledge about the effects of physical inactivity and anti-inflammatory medications on the development of cardiovascular disease, and their misperception of cardiovascular risk was common. As a preventive measure, educational programs about cardiovascular disease should be tailored specifically for patients with rheumatoid arthritis, and behavioral interventions, including routine exercise, should be made available at the time of diagnosis.

Psychological Outcomes After a False Positive Mammogram: Preliminary Evidence for Ethnic Differences Across Time

Adverse psychological consequences of screening mammography are well-documented for women who receive a false positive result. However, little is known about ethnic differences. To address this gap, we examine distress associated with an abnormal mammogram (results-related distress) and perceived lifetime risk of breast cancer (perceived risk) among Latinas and non-Latina White (NLW) women 3 months after receipt of a false positive result. A sample of 28 Latina and 27 NLW women who received an initial abnormal mammogram result and later, a definitive non-cancer diagnosis were recruited for this descriptive, longitudinal study. Women were interviewed twice: within 30 days and 3 months after a false positive result. Questionnaires included standard sociodemographic questions, the Impact of Events Scale-Revised, and two perceived breast cancer risk items. All participants experienced decreased distress 3 months after the initial results. Latinas experienced higher levels of distress, F(1,45) = 4.58, p = 0.04, and had a significant increase in perceived breast cancer risk over time, F(1,45) = 3.99, p = 0.05. Larger population-based studies are necessary to confirm ethnic differences in mental health consequences of false positive results. Given cultural emphases concerning respect for authority figures, healthcare professionals may be particularly helpful in working with Latinas to mitigate distress and clarify accurate perceptions of breast cancer risk through evidence-based practice.

Investigating young women's motivations to engage in early mammography screening in Switzerland: results of a cross-sectional study

BACKGROUND

The scientific and public debate concerning organized mammography screening is unprecedentedly strong. With research evidence concerning its efficacy being ambiguous, the recommendations pertaining to the age-thresholds for program inclusion vary between - and even within - countries. Data shows that young women who are not yet eligible for systematic screening, have opportunistic mammograms relatively often and, moreover, want to be included in organized programs. Yet, to date, little is known about the precise motivations underlying young women's desire and intentions to go for, not medically indicated, mammographic screening.

METHODS

A cross-sectional online survey was carried out among women aged 30-49 years (n = 918) from Switzerland.

RESULTS

The findings show that high fear (β = .08, p ≤ .05), perceived susceptibility (β = .10, p ≤ .05), and ego-involvement (β = .34, p ≤ .001) are the main predictors of screening intentions among women who are not yet eligible for the systematic program. Also, geographical location (Swiss-French group: β = .15, p ≤ .001; Swiss-Italian group: β = .26, p ≤ .001) and age (β = .11, p ≤ .001) play a role. In turn, breast cancer knowledge, risk perceptions, and educational status do not have a significant impact.

CONCLUSIONS

Young women seem to differ inherently from those who are already eligible for systematic screening in terms of the factors underlying their intentions to engage in mammographic screening. Thus, when striving to promote adherence to systematic screening guidelines - whether based on unequivocal scientific evidence or policy decisions - and to allow women to make evidence-based, informed decisions about mammography, differential strategies are needed to reach different age-groups.

Motivations for contralateral prophylactic mastectomy as a function of socioeconomic status

Background

Despite no demonstrated survival advantage for women at average risk of breast cancer, rates of contralateral prophylactic mastectomy (CPM) continue to increase. Research reveals women with higher socioeconomic status (SES) are more likely to select CPM. This study examines how indicators of SES, age, and disease severity affect CPM motivations.

Methods

Patients (N = 113) who underwent CPM at four Indiana University affiliated hospitals completed telephone interviews in 2013. Participants answered questions about 11 CPM motivations and provided demographic information. Responses to motivation items were factor analyzed, resulting in 4 motivational factors: reducing long-term risk, symmetry, avoiding future medical visits, and avoiding treatments.

Results

Across demographic differences, reducing long-term risk was the strongest CPM motivation. Lower income predicted stronger motivation to reduce long-term risk and avoid treatment. Older participants were more motivated to avoid treatment; younger and more-educated patients were more concerned about symmetry. Greater severity of diagnosis predicted avoiding treatments.

Conclusions

Reducing long-term risk is the primary motivation across groups, but there are also notable differences as a function of age, education, income, and disease severity. To stop the trend of increasing CPM, physicians must tailor patient counseling to address motivations that are consistent across patient populations and those that vary between populations.

The impact of doctor-patient communication on patients' perceptions of their risk of breast cancer recurrence

PURPOSE

Doctor-patient communication is the primary way for women diagnosed with breast cancer to learn about their risk of distant recurrence. Yet little is known about how doctors approach these discussions.

METHODS

A weighted random sample of newly diagnosed early-stage breast cancer patients identified through SEER registries of Los Angeles and Georgia (2013-2015) was sent surveys about ~2 months after surgery (Phase 2, N = 3930, RR 68%). We assessed patient perceptions of doctor communication of risk of recurrence (i.e., amount, approach, inquiry about worry). Clinically determined 10-year risk of distant recurrence was established for low and intermediate invasive cancer patients. Women's perceived risk of distant recurrence (0-100%) was categorized into subgroups: overestimation, reasonably accurate, and zero risk. Understanding of risk and patient factors (e.g. health literacy, numeracy, and anxiety/worry) on physician communication outcomes was evaluated in multivariable regression models (analytic sample for substudy = 1295).

RESULTS

About 33% of women reported that doctors discussed risk of recurrence as "quite a bit" or "a lot," while 14% said "not at all." Over half of women reported that doctors used words and numbers to describe risk, while 24% used only words. Overestimators (OR .50, CI 0.31-0.81) or those who perceived zero risk (OR .46, CI 0.29-0.72) more often said that their doctor did not discuss risk. Patients with low numeracy reported less discussion. Over 60% reported that their doctor almost never inquired about worry.

CONCLUSIONS

Effective doctor-patient communication is critical to patient understanding of risk of recurrence. Efforts to enhance physicians' ability to engage in individualized communication around risk are needed.

Psychosocial factors associated with the uptake of contralateral prophylactic mastectomy among BRCA1/2 mutation noncarriers with newly diagnosed breast cancer

PURPOSE

Women who are newly diagnosed with breast cancer may consider contralateral prophylactic mastectomy (CPM) to reduce their future risk of cancer in their unaffected breast. Pre-surgical BRCA1/2 genetic testing can provide valuable risk information to guide this choice. However, little is understood about why BRCA1/2 mutation noncarriers, who are generally not at substantially elevated risk of contralateral disease, select CPM.

METHODS

We examined the uptake of CPM among breast cancer patients identified as BRCA1/2 mutation noncarriers (n = 92) as part of a larger prospective study of the impact of pre-surgical BRCA1/2 testing. Data obtained from self-report questionnaires and patient medical records were used to examine associations between theoretically relevant background and psychosocial factors and BRCA1/2 mutation noncarriers' decisions to undergo CPM.

RESULTS

Among BRCA1/2 mutation noncarriers, 25% (n = 23) elected to undergo CPM. Psychosocial factors including a self-reported physician recommendation for CPM, greater perceived contralateral breast cancer risk, and greater perceived benefits of CPM were all significantly associated with the uptake of CPM.

CONCLUSIONS

A sizeable minority of BRCA1/2 mutation noncarriers choose to undergo CPM after learning their mutation status through pre-surgical genetic testing. BRCA1/2 mutation noncarriers' cognitive perceptions and social influences appear to be important in shaping their decisions regarding CPM. This work highlights the importance of several psychosocial factors in influencing patients' surgical decisions. Future research is needed that examines the formation of BRCA1/2 mutation noncarriers' beliefs regarding their disease and available treatment options, and that characterizes the physician-patient communication that occurs in this complex decision-making context.

Disparities in contralateral prophylactic mastectomy use among women with early-stage breast cancer

Contralateral prophylactic mastectomy use has increased over the past decades among women with early-stage breast cancer. Racial differences in contralateral prophylactic mastectomy use are well described, but with unclear causes. This study examined contralateral prophylactic mastectomy use among black and white women and the contribution of differences in perceived risk to differences in use. We surveyed women diagnosed with early-stage unilateral breast cancer between ages 41-64 in Pennsylvania and Florida between 2007-2009 to collect data on breast cancer treatment, family history, education, income, insurance, and perceived risk. Clinical factors-age,stage at diagnosis, receptor status-were obtained from cancer registries. The relationships between patient factors and contralateral prophylactic mastectomy were assessed using logistic regression. The interaction between race and contralateral prophylactic mastectomy on the perceived risk of second breast cancers was tested using linear regression. Of 2182 study participants, 18% of whites underwent contralateral prophylactic mastectomy compared with 10% of blacks (p < 0.001). The racial difference remained after adjustment for clinical factors and family history (odds ratio = 2.32, 95% confidence interval 1.76-3.06, p < 0.001). The association between contralateral prophylactic mastectomy and a reduction in the perceived risk of second breast cancers was significantly smaller for blacks than whites. Blacks were less likely than whites to undergo contralateral prophylactic mastectomy even after adjustment for clinical factors. This racial difference in use may relate to the smaller impact of contralateral prophylactic mastectomy on the perceived risk of second breast cancers among blacks than among whites. Future research is needed to understand the overall impact of perceived risk on decisions about contralateral prophylactic mastectomy and how that may explain racial differences in use.

Breast Cancer Risk Assessment at the Time of Screening Mammography: Perceptions and Clinical Management Outcomes for Women at High Risk

The purpose of this study was to evaluate the utility of a breast cancer risk assessment (BCRA) at the time of screening mammogram. Women whose BCRA indicated a high risk for cancer received a letter with instructions for breast health care and genetic counseling if appropriate. After 6 months this group received surveys to evaluate their risk perception and their recall of, and compliance with, recommendations. We also explored the impact of other variables such as a recommendation for genetic counseling and physician communication with the women. After the BCRA, the majority of high risk women reported no change in their perceived risk of cancer. A woman's perceived risk of cancer after a BCRA was significantly associated with her recall of recommendations for breast health care, but not with compliance. A recommendation for genetic counseling was not significantly related to women's perceived risk of cancer after the BCRA. Ten percent of women who should have obtained genetic counseling actually completed an appointment. Women who discussed their BCRA results with their physicians were more compliant with a six month breast exam with a doctor (53% vs 17%, p = 0.018). Overall, women felt that the BCRA was helpful and did not cause undue stress or anxiety. Although the cohort's compliance with recommendations was suboptimal, physicians' interactions with their patients may have a positive influence on their compliance.

How do women at increased breast cancer risk perceive and decide between risks of cancer and risk-reducing treatments? A synthesis of qualitative research

Objective

Risk‐reducing procedures can be offered to people at increased cancer risk, but many procedures can have iatrogenic effects. People therefore need to weigh risks associated with both cancer and the risk‐reduction procedure in their decisions. By reviewing relevant literature on breast cancer (BC) risk reduction, we aimed to understand how women at relatively high risk of BC perceive their risk and how their risk perceptions influence their decisions about risk reduction.

Methods

Synthesis of 15 qualitative studies obtained from systematic searches of SCOPUS, Web of Knowledge, PsychINFO, and Medline electronic databases (inception‐June 2015).

Results

Women did not think about risk probabilistically. Instead, they allocated themselves to broad risk categories, typically influenced by their own or familial experiences of BC. In deciding about risk‐reduction procedures, some women reported weighing the risks and benefits, but papers did not describe how they did so. For many women, however, an overriding wish to reduce intense worry about BC led them to choose aggressive risk‐reducing procedures without such deliberation.

Conclusions

Reasoning that categorisation is a fundamental aspect of risk perception, we argue that patients can be encouraged to develop more nuanced and accurate categorisations of their own risk through their interactions with clinicians. Empirically‐based ethical reflection is required to determine whether and when it is appropriate to provide risk‐reduction procedures to alleviate worry.

Personal Genomic Testing for Cancer Risk: Results From the Impact of Personal Genomics Study

Purpose Significant concerns exist regarding the potential for unwarranted behavior changes and the overuse of health care resources in response to direct-to-consumer personal genomic testing (PGT). However, little is known about customers' behaviors after PGT. Methods Longitudinal surveys were given to new customers of 23andMe (Mountain View, CA) and Pathway Genomics (San Diego, CA). Survey data were linked to individual-level PGT results through a secure data transfer process. Results Of the 1,042 customers who completed baseline and 6-month surveys (response rate, 71.2%), 762 had complete cancer-related data and were analyzed. Most customers reported that learning about their genetic risk of cancers was a motivation for testing (colorectal, 88%; prostate, 95%; breast, 94%). No customers tested positive for pathogenic mutations in highly penetrant cancer susceptibility genes. A minority of individuals received elevated single nucleotide polymorphism-based PGT cancer risk estimates (colorectal, 24%; prostate, 24%; breast, 12%). At 6 months, customers who received elevated PGT cancer risk estimates were not significantly more likely to change their diet, exercise, or advanced planning behaviors or engage in cancer screening, compared with individuals at average or reduced risk. Men who received elevated PGT prostate cancer risk estimates changed their vitamin and supplement use more than those at average or reduced risk (22% v 7.6%, respectively; adjusted odds ratio, 3.41; 95% CI, 1.44 to 8.18). Predictors of 6-month behavior include baseline behavior (exercise, vitamin or supplement use, and screening), worse health status (diet and vitamin or supplement use), and older age (advanced planning, screening). Conclusion Most adults receiving elevated direct-to-consumer PGT single nucleotide polymorphism-based cancer risk estimates did not significantly change their diet, exercise, advanced care planning, or cancer screening behaviors.

Health literacy and the perception of risk in a breast cancer family history clinic

BACKGROUND

Informed consent is an essential component of medical practice, and especially so in procedural based specialties which entail varying degrees of risk. Breast cancer is one of the most common cancers in women, and as such is the focus of extensive research and significant media attention. Despite this, considerable misperception exists regarding the risk of developing breast cancer.

AIMS

This study aims to examine the accuracy of risk perception of women attending a breast cancer family history clinic, and to explore the relationship between risk perception accuracy and health literacy.

METHODS

A cross-sectional study of women attending a breast cancer family history clinic (n = 86) was carried out, consisting of a patient survey and a validated health literacy assessment. Patients' perception of personal and population breast cancer risk was compared to actual risk as calculated by a validated risk assessment tool.

RESULTS

Significant discordance between real and perceived risks was observed. The majority (83.7%) of women overestimated their personal lifetime risk of developing breast cancer, as well as that of other women of the same age (89.5%). Health literacy was considered potentially inadequate in 37.2% of patients; there was a correlation between low health literacy and increased risk perception inaccuracy across both personal ten-year (r_s = 0.224, p = 0.039) and general ten-year population estimations. (r_s = 0.267, p = 0.013).

CONCLUSION

Inaccuracy in risk perception is highly prevalent in women attending a breast cancer family history clinic. Health literacy inadequacy is significantly associated with this inaccuracy.

Associations of perceived risk and cancer worry for colorectal cancer with screening behaviour

We investigated the associations of perceived risk and cancer worry with colorectal cancer screening by the faecal occult blood test, colonoscopy or both. This study was based on the 2013 Korean National Cancer Screening Survey, including 2154 randomly selected, cancer-free and over 50-year-old adults. Individuals with higher cancer worry were 1.53 times more likely to undergo colorectal cancer screening, influenced by emotional reaction; individuals with greater perceived risk were 1.61 times more, affected by subjective awareness. However, cancer worry was only associated with the faecal occult blood test. Better understanding of cancer worry and perceived risk on screening behaviours may help to increase colorectal cancer screening rates.

Predictors of Breast Cancer Worry in a Hispanic and Predominantly Immigrant Mammography Screening Population

OBJECTIVE

Worry about developing breast cancer (BC) has been associated with participation in screening and genetic testing and with follow-up of abnormal screening results. Little is known about the scope and predictors of BC worry in Hispanic and immigrant populations.

METHODS

We collected in-person interview data from 250 self-identified Hispanic women recruited from an urban mammography facility (average age 50.4 years; 82% foreign-born). Women reported whether they worried about developing breast cancer rarely/never (low worry), sometimes (moderate worry), or often/all the time (high worry). We examined whether sociocultural and psychological factors (e.g., acculturation, education, perceived risk), and risk factors and objective risk for BC (e.g., family history, Gail model 5-year risk estimates, parity) predicted BC worry using multinomial and logistic regression.

RESULTS

In multivariable models, women who perceived higher absolute BC risk (odds ratio, 1.66 [95% confidence interval, 1.28-2.14] for a one-unit increase in perceived lifetime risk) and comparative BC risk (e.g., odds ratio, 2.73, 95% confidence interval, 1.23-6.06) were more likely to report high BC worry than moderate or low BC worry. There were no associations between BC worry and indicators of objective risk or acculturation.

CONCLUSIONS

In Hispanic women undergoing screening mammography, higher perceptions of BC risk, in both absolute and comparative terms, were associated independently with high BC worry, and were stronger predictors of BC worry than indicators of objective BC risk, including family history, mammographic density, and personal BC risk estimates.

Patient and Provider Perspectives on Mammographic Breast Density Notification Legislation

Background: Patient advocacy has fostered the implementation of mammographic breast density (MBD) notification legislation in many states. Little is known about the perspectives of women, primary care physicians (PCPs), and breast radiologists in response to this legislation. The objective of this research was to elicit qualitative information from these multiple stakeholders to understand varied perspectives on the subject of MBD notification and inform best practices around implementation. Methods: Content analysis of narrative data from focus groups with women (2 groups, total of 16 participants) and in-depth interviews with PCPs (n = 7) and breast radiologists (n = 7). Results: Three major themes emerged from the data: 1) knowledge and general attitudes about legislation, 2) concerns about consequences, and 3) actions patients and clinicians should consider based on MBD information. For each of these themes, the views of women, PCPs, and radiologists often demonstrated different perspectives. Conclusion: This work supports the need for clear and concise tools for patients and providers to understand MBD in the context of a woman's overall breast cancer risk with guidance on next steps.

How are lung cancer risk perceptions and cigarette smoking related?-testing an accuracy hypothesis

Background

Subjective risk perception is an important theoretical construct in the field of cancer prevention and control. Although the relationship between subjective risk perception and health behaviors has been widely studied in many health contexts, the causalities and associations between the risk perception of developing lung cancer and cigarette smoking have been inconsistently reported among studies. Such inconsistency may be from discrepancies between study designs (cross-sectional versus longitudinal designs) and the three hypotheses (i.e., the behavior motivation hypothesis, the risk reappraisals hypothesis, and the accuracy hypothesis) testing different underlying associations between risk perception and cigarette-smoking behaviors. To clarify this issue, as an initial step, we examined the association between absolute and relative risk perceptions of developing lung cancer and cigarette-smoking behaviors among a large, national representative sample of 1,680 U.S. adults by testing an accuracy hypothesis (i.e., people who smoke accurately perceived a higher risk of developing lung cancer).

Methods

Data from the U.S. Health Information National Trends Survey (HINTS) were analyzed using logistic regression and multivariate linear regression to examine the associations between risk perception and cigarette-smoking behaviors among 1,680 U.S. adults.

Results

Findings from this cross-sectional survey suggest that absolute and relative risk perceptions were positively and significantly correlated with having smoked >100 cigarettes during lifetime and the frequency of cigarette smoking. Only absolute risk perception was significantly associated with the number of cigarettes smoked per day among current smokers.

Conclusions

Because both absolute and relative risk perceptions are positively related to most cigarette-smoking behaviors, this study supports the accuracy hypothesis. Moreover, absolute risk perception might be a more sensitive measurement than relative risk perception for perceived lung cancer risk. Longitudinal research is needed in the future to investigate other types of risk perception-risk behavior hypotheses-the behavior motivation and the risk reappraisals hypotheses-among nationally representative samples to further examine the causations between risk perception of obtaining lung cancer and smoking behaviors.

Effects of a risk-based online mammography intervention on accuracy of perceived risk and mammography intentions

OBJECTIVE

This experiment tested the effects of an individualized risk-based online mammography decision intervention. The intervention employs exemplification theory and the Elaboration Likelihood Model of persuasion to improve the match between breast cancer risk and mammography intentions.

METHODS

2918 women ages 35-49 were stratified into two levels of 10-year breast cancer risk (<1.5%; ≥1.5%) then randomly assigned to one of eight conditions: two comparison conditions and six risk-based intervention conditions that varied according to a 2 (amount of content: brief vs. extended) x 3 (format: expository vs. untailored exemplar [example case] vs. tailored exemplar) design. Outcomes included mammography intentions and accuracy of perceived breast cancer risk.

RESULTS

Risk-based intervention conditions improved the match between objective risk estimates and perceived risk, especially for high-numeracy women with a 10-year breast cancer risk ≤1.5%. For women with a risk≤1.5%, exemplars improved accuracy of perceived risk and all risk-based interventions increased intentions to wait until age 50 to screen.

CONCLUSION

A risk-based mammography intervention improved accuracy of perceived risk and the match between objective risk estimates and mammography intentions.

PRACTICE IMPLICATIONS

Interventions could be applied in online or clinical settings to help women understand risk and make mammography decisions.

Exploring breast health practices of post-menopausal women: Implications to informed consent

In light of the contention surrounding breast health practices, the research aimed to explore post-menopausal women's experiences of such practices. Semi-structured interviews were conducted in July and August 2015 with 13 Australian women aged 54-74 years. Data were analysed thematically. Participants deemed their engagement with breast health practices as the 'right' thing. However, engaging in these 'right' practices appeared to be fostered by misconceptions. The findings suggest that women may not be making evidence-informed decisions to engage in breast screening; identify contemporary barriers to promoting informed decisions; and may inform information pertinent to breast screening policy, campaigns and decision aid designs.

Let the Individuals Directly Concerned Decide: A Solution to Tragic Choices in Genetic Risk Information

Health-care systems as well as legislators and society seem largely unprepared to face and manage the massive production of genetic risk information. Ethics committees and professional bodies usually do not involve the individuals directly concerned in defining guidelines for genetic risk communication. Therefore, they do not always reflect people's needs and preferences. We argue in this article that we currently experience a cultural shift in medicine where individuals' concerns and preferences regarding genetic risk information are playing a more significant role than before, and that this should have some normative implications. We are going toward a situation where individual citizens are approached as consumers by personal genomics companies [Prainsack: Account Res 2011;18:132-147]. In clinical and research contexts, individuals are also increasingly informed about their own responsibilities for counterbalancing their genetic risk by making individual health care and lifestyle choices. In this situation, communication of genetic risk information may rather be regulated like traffic and markets in which consumers' decision-making power has a fundamental role in the management and regulation of how a service should be provided, as well as in the creation of policy and legislation. We acknowledge that markets may be different depending on different genetic conditions. For example, genetic risk communication for rare diseases, where a close relationship with clinicians is of paramount significance, should be differently regulated than personal genetic profiles of complex diseases, where contributing risk factors related to lifestyle are modifiable by the individual.

The use of cardiac rehabilitation services to aid the recovery of patients with bowel cancer: a pilot randomised controlled trial with embedded feasibility study

Background

Colorectal cancer (CRC) survivors are not meeting the recommended physical activity levels associated with improving their chances of survival and quality of life. Rehabilitation could address this problem.

Objectives

The aims of the Cardiac Rehabilitation In Bowel cancer study were to assess whether or not cardiac rehabilitation is a feasible and acceptable model to aid the recovery of people with CRC and to test the feasibility and acceptability of the protocol design.

Design

Intervention testing and feasibility work (phase 1) and a pilot randomised controlled trial with embedded qualitative study (phase 2), supplemented with an economic evaluation. Randomisation was to cardiac rehabilitation or usual care. Outcomes were differences in objective measures of physical activity and sedentary behaviour, self-reported measures of quality of life, anxiety, depression and fatigue. Qualitative work involved patients and clinicians from both cancer and cardiac specialties.

Setting

Three colorectal cancer wards and three cardiac rehabilitation facilities.

Participants

Inclusion criteria were those who were aged > 18 years, had primary CRC and were post surgery.

Results

Phase 1 (single site) – of 34 patient admissions, 24 (70%) were eligible and 4 (17%) participated in cardiac rehabilitation. Sixteen clinicians participated in an interview/focus group. Modifications to trial procedures were made for further testing in phase 2. Additionally, 20 clinicians in all three sites were trained in cancer and exercise, rating it as excellent. Phase 2 (three sites) – screening, eligibility, consent and retention rates were 156 (79%), 133 (67%), 41 (31%) and 38 (93%), respectively. Questionnaire completion rates were 40 (97.5%), 31 (75%) and 25 (61%) at baseline, follow-up 1 and follow-up 2, respectively. Forty (69%) accelerometer data sets were analysed; 20 (31%) were removed owing to invalid data.

Qualitative study

CRC and cardiac patients and clinicians were interviewed. Key themes were benefits and barriers for people with CRC attending cardiac rehabilitation; generic versus disease-specific rehabilitation; key concerns of the intervention; and barriers to participation (CRC participants only).

Economic evaluation

The average out-of-pocket expenses of attending cardiac rehabilitation were £50. The costs of cardiac rehabilitation for people with cancer are highly dependent on whether it involves accommodating additional patients in an already existing service or setting up a completely new service.

Limitations and conclusions

The main limitation is that this is a small feasibility and pilot study. The main novel finding is that cardiac rehabilitation for cancer and cardiac patients together is feasible and acceptable, thereby challenging disease-specific rehabilitation models.

Future work

This study highlighted important challenges to doing a full-scale trial of cardiac rehabilitation but does not, we believe, provide sufficient evidence to reject the possibility of such a future trial. We recommend that any future trial must specifically address the challenges identified in this study, such as suboptimal consent, completion, missing data and intervention adherence rates and recruitment bias, and that an internal pilot trial be conducted. This should have clear ‘stop–proceed’ rules that are formally reviewed before proceeding to the full-scale trial.

A Video Game Promoting Cancer Risk Perception and Information Seeking Behavior Among Young-Adult College Students: A Randomized Controlled Trial

Background

Risky behaviors tend to increase drastically during the transition into young adulthood. This increase may ultimately facilitate the initiation of carcinogenic processes at a young age, highlighting a serious public health problem. By promoting information seeking behavior (ISB), young adults may become aware of cancer risks and potentially take preventive measures.

Objective

Based on the protection motivation theory, the current study seeks to evaluate the impact of challenge in a fully automated video game called Re-Mission on young adult college students' tendency to perceive the severity of cancer, feel susceptible to cancer, and engage in ISB.

Methods

A total of 216 young adults were recruited from a university campus, consented, screened, and randomized in a single-blinded format to 1 of 3 conditions: an intervention group playing Re-Mission at high challenge (HC; n=85), an intervention group playing Re-Mission at low challenge (LC; n=81), and a control group with no challenge (NC; presented with illustrated pictures of Re-Mission; n=50). Measurement was conducted at baseline, immediate posttest, 10-day follow-up, and 20-day follow-up. Repeated-measures mixed-effect models were conducted for data analysis of the main outcomes.

Results

A total of 101 young adults continued until 20-day follow-up. Mixed-effect models showed that participants in the HC and LC groups were more likely to increase in perceived susceptibility to cancer (P=.03), perceived severity of cancer (P=.02), and ISB (P=.01) than participants in the NC group. The LC group took until 10-day follow-up to show increase in perceived susceptibility (B=0.47, standard error (SE) 0.16, P=.005). The HC group showed an immediate increase in perceived susceptibility at posttest (B=0.43, SE 0.14, P=.002). The LC group exhibited no changes in perceived severity (B=0.40, SE 0.33, P=.24). On the other hand, the HC group showed a significant increase from baseline to posttest (B=0.39, SE 0.14, P=.005), maintaining this increase until 20-day follow-up (B=−0.007, SE 0.26, P=.98). Further analyses indicated that perceived threat from virtual cancer cells in the game is related to the increase in perceived severity (B=0.1, SE 0.03, P=.001), and perceived susceptibility is related to changes in ISB at 10-day follow-up (B=0.21, SE 0.08, P=.008).

Conclusions

The feature of challenge with cancer cells in a virtual environment has the potential to increase cancer risk perception and ISB. The results are promising considering that the Re-Mission intervention was neither designed for cancer risk communication, nor applied among healthy individuals. Further research is needed to understand the theoretical framework underlying the effects of Re-Mission on ISB. The findings call for the development of a Web-based, game-based intervention for cancer risk communication and information seeking among young adults.

Genetic testing and personalized ovarian cancer screening: a survey of public attitudes

Background

Advances in genetic technologies are expected to make population-wide genetic testing feasible. This could provide a basis for risk stratified cancer screening; but acceptability in the target populations has not been explored.

Methods

We assessed attitudes to risk-stratified ovarian cancer (OC) screening based on prior genetic risk assessment using a survey design. Home-based interviews were carried out by the UK Office of National Statistics in a population-based sample of 1095 women aged 18–74. Demographic and personal correlates of attitudes to risk-stratified OC screening based on prior genetic risk assessment were determined using univariate analyses and adjusted logistic regression models.

Results

Full data on the key analytic questions were available for 829 respondents (mean age 46 years; 27 % ‘university educated’; 93 % ‘White’). Relatively few respondents felt they were at ‘higher’ or ‘much higher’ risk of OC than other women of their age group (7.4 %, n = 61). Most women (85 %) said they would ‘probably’ or ‘definitely’ take up OC genetic testing; which increased to 88 % if the test also informed about breast cancer risk. Almost all women (92 %) thought they would ‘probably’ or ‘definitely’ participate in risk-stratified OC screening. In multivariate logistic regression models, university level education was associated with lower anticipated uptake of genetic testing (p = 0.009), but with more positive attitudes toward risk-stratified screening (p <0.001). Perceived risk was not significantly associated with any of the outcome variables.

Conclusions

These findings give confidence in taking forward research on integration of novel genomic technologies into mainstream healthcare.

Heart disease and breast cancer perceptions: Ethnic differences and relationship to attentional bias

Differences in perceptions of susceptibility, seriousness, and fear of heart disease and breast cancer were examined and related to attentional bias for disease-related words among Canadian women of various ethnic ancestry. Women (n = 831) completed an online survey, and 503, among them, also completed an attentional bias task. Perceived seriousness of breast cancer predicted attentional bias for breast cancer in women of South Asian ancestry. Lifestyle behaviors were related to breast cancer attentional bias in women with British ancestry. Understanding relationships between modifiable risk factors, disease risk perceptions, and attentional biases among different ethnic groups can help create targeted promotional campaigns.

Noncompliance in cancer screening trials

Background Randomized trials evaluating new cancer screening technologies may underestimate the efficacy of screening to reduce cancer mortality if study participants are noncompliant. Participants may fail to comply with the screening itself or fail to obtain appropriate diagnostic follow-up and treatment. Noncompliance with screening has drawn wide attention, but little attention has been paid to noncompliance with diagnostic follow-up and treatment.

Purpose To examine the importance of noncompliance with screening, follow-up, and treatment in cancer screening trials.

Methods The unique problems associated with noncompliance in screening trials are described and provide an example illustrating the potential impact of noncompliance in a screening trial. I discuss issues that arise with measurement of follow-up and therapeutic noncompliance, and the benefit of collecting information on health system and participant characteristics associated with noncompliance.

Results The estimate of the efficacy of a screening program on cancer mortality can be adjusted for screening, follow-up, and treatment noncompliance. Noncompliance needs to be measured in a rigorous, systematic manner across all arms of the trial. Information on health system and participant characteristics associated with compliance may also be incorporated into statistical models to estimate screening effects with full compliance, plan interventions to increase compliance, and extrapolate results of screening trials from one population to another.

Limitations Measuring compliance with follow-up and treatment can be difficult when these occur outside the trial, and when there is variation among providers in follow-up and treatment practices.

Conclusions Noncompliance may alter the estimate of a screening effect on cancer mortality in clinical trials. It is possible to adjust screening efficacy estimates for noncompliance using existing statistical techniques. It is important that data describing compliance with screening, follow-up, and treatment are collected as part of standard data collection in cancer screening trials.

The Relationship of Perceived Risk and Biases in Perceived Risk to Fracture Prevention Behavior in Older Women

BACKGROUND

A bias in perceived risk for health outcomes, including fracture, exists.

PURPOSE

We compared perceived risk and biases in perceived risk for fracture to fracture preventive behavior.

METHODS

Women over age 55 (n = 2874) completed a survey five times over 5 years, and data was pulled from the medical record. Perceived risk was measured by asking women to rate their risk of fracture compared to similar women. Actual risk was measured using FRAX score. Bias was measured using an interaction between perceived and actual risk.

RESULTS

Higher perceived risk was related to lower quality of life and self-reported health, more medication and calcium use, increased bone density scan use, and less walking. Bias was only associated with less medication use. Neither perceived risk nor bias predicted medication adherence.

CONCLUSIONS

Perceived risk, but not bias, may predict different fracture prevention behaviors. Clinicians may need to base interventions on risk perceptions.

Risk perception in pregnancy: a concept analysis

AIM

To report an analysis of the concept of risk perception in pregnancy.

BACKGROUND

Pregnant women are increasingly exposed to the view that pregnancy and childbirth are intrinsically dangerous, requiring medical monitoring and management. Societal pressures are applied to women that dictate appropriate behaviours during pregnancy. These changes have resulted in increased perception of risk for pregnant women.

DESIGN

Walker and Avant's method was selected to guide this analysis.

DATA SOURCES

Peer-reviewed articles published in English from CINAHL, Scopus, PubMed and Psychinfo. No date limits were applied.

METHODS

Thematic analysis was conducted on 79 articles. Attributes, antecedents and consequences of the concept were identified.

RESULTS

The attributes of the concept are the possibility of harm to mother or infant and beliefs about the severity of the risk state. The physical condition of pregnancy combined with the cognitive ability to perceive a personal risk state is antecedents. Risk perception in pregnancy influences women's affective state and has an impact on decision-making about pregnancy and childbirth. There are limited empirical referents with which to measure the concept.

CONCLUSION

Women today know more about their developing infant than at any other time in history; however, this has not led to a sense of reassurance. Nurses and midwives have a critical role in assisting pregnant women, and their families make sense of the information they are exposed to. An understanding of the complexities of the concept of risk perception in pregnancy may assist in enabling nurses and midwives to reaffirm the normalcy of pregnancy.

Factorial validity and measurement invariance of the Perceived Susceptibility to Sport Injury scale

The Perceived Susceptibility to Sport Injury (PSSI) scale is a measure that has recently surfaced in the sport injury literature. The factor structure of the PSSI scale has not been subjected to a rigorous factor analysis; thus, the factorial validity of the measure in athlete populations is unknown. To establish the validity of the PSSI scale in sports medicine research, the purpose of this study was to examine the factor structure and measurement invariance across gender of the PSSI scale. Male and female intercollegiate athletes (N = 217) completed the PSSI scale during the off-season. The factor structure was analyzed using confirmatory factor analysis (CFA) procedures and maximum likelihood estimation. The measurement invariance analysis was conducted via comparisons of fit indices within a series of hierarchically constrained models. Results of the CFA yielded a very good fit of the measurement model: χ² (2) = 4.535, P = 0.104; RMSEA = 0.076; SRMR = 0.018; CFI = 0.995; NNFI = 0.985. Results of the measurement invariance analysis demonstrated strict invariance across gender, and no significant latent mean differences emerged between men and women. Study results support the factorial validity of the PSSI scale for use in future sports medicine research.

Breast Cancer Risk Perceptions among Relatives of Women with Uninformative Negative BRCA1/2 Test Results: The Moderating Effect of the Amount of Shared Information

The most common result of BRCA1/2 mutation testing when performed in a family without a previously identified mutation is an uninformative negative test result. Women in these families may have an increased risk for breast cancer because of mutations in non-BRCA breast cancer predisposition genes, including moderate- or low-risk genes, or shared environmental factors. Genetic counselors often encourage counselees to share information with family members, however it is unclear how much information counselees share and the impact that shared information may have on accuracy of risk perception in family members. We evaluated 85 sisters and daughters of women who received uninformative negative BRCA1/2 results. We measured accuracy of risk perception using a latent variable model where accuracy was represented as the correlation between perceived risk (indicators = verbal and quantitative measures) and calculated risk (indicators = Claus and BRCAPRO). Participants who reported more information was shared with them by their sister or mother about her genetic counseling session had greater accuracy of risk perception (0.707, p = 0.000) than those who reported little information was shared (0.326, p = 0.003). However, counselees shared very little information; nearly 20 % of family members reported their sister or mother shared nothing with them about her genetic counseling. Family members were generally not aware of the existence of a genetic counseling summary letter. Our findings underscore the need for effective strategies that facilitate counselees to share information about their genetic counseling sessions. Such communication may help their relatives better understand their cancer risks and enhance risk appropriate cancer prevention.

A Randomized Trial of Human Papillomavirus Self-Sampling as an Intervention to Promote Cervical Cancer Screening Among Women With HIV

OBJECTIVE

Women living with HIV experience higher risk of cervical cancer, but screening rates in the United States are lower than recommended. The purpose of this study was to examine whether an intervention using self-sampling of cervicovaginal cells for human papillomavirus (HPV) with results counseling would increase cervical cytology ("Pap") testing among women with HIV.

MATERIALS AND METHODS

This was a randomized controlled trial to test the effectiveness of an intervention of self-sampling for HPV and results counseling. Participants were 94 women older than 18 years, with HIV infection, attending an HIV clinic for a primary care visit, whose last cervical cancer screening was 18 months or more before baseline. Women were assigned to the intervention or information-only group. The primary outcome was completion of cervical cytology testing within 6 months of baseline. The secondary outcome was the women's perceived threat of developing cervical cancer.

RESULTS

A total of 94 women were enrolled and analyzed in the study. The cytology completion rate overall was 35% by 6 months from baseline. There were no differences in comparing HPV-positive with HPV-negative women nor comparing them with the information-only group. In the intervention group, a positive HPV test increased perceived threat of cervical cancer.

CONCLUSIONS

The intervention did not improve cytology test attendance, although education about HPV and cervical cancer risk as part of study procedures was associated with testing for 35% of this group of women whose previous cytology occurred an average of 3.6 years before the baseline appointment. Self-sampling for HPV testing was feasible.

Adherence to the breast cancer surveillance program for women at risk for familial breast and ovarian cancer versus overscreening: a monocenter study in Germany

Breast cancer (BC) is the leading cancer among women worldwide and in 5-10 % of cases is of hereditary origin, mainly due to BRCA1/2 mutations. Therefore, the German Consortium for Familial Breast and Ovarian Cancer (HBOC) with its 15 specialized academic centers offers families at high risk for familial/hereditary cancer a multimodal breast cancer surveillance program (MBCS) with regular breast MRI, mammography, ultrasound, and palpation. So far, we know a lot about the psychological effects of genetic testing, but we know little about risk-correlated adherence to MBCS or prophylactic surgery over time. The aim of this study was to investigate counselees' adherence to recommendations for MBCS in order to adjust the care supply and define predictors for incompliance. All counselees, who attended HBOC consultation at the University Hospital Heidelberg between July 01, 2009 and July 01, 2011 were eligible to participate. A tripartite questionnaire containing sociodemographic information, psychological parameters, behavioral questions, and medical data collection from the German consortium were used. A high participation rate was achieved among the study population, with 72 % returning the questionnaire. This study showed a rate of 59 % of full-adherers to the MBCS. Significant predictors for partial or full adherence were having children (p = 0.0221), younger daughters (p = 0.01795), a higher awareness of the topic HBOC (p = 0.01795, p < 0.0001), a higher perceived breast cancer risk (p < 0.0001), and worries (p = 0.0008)/impairment (p = 0.0257) by it. Although the current data suggest a good adherence of MBCS, prospective studies are needed to understand counselees' needs to further improve surveillance programs and adherence to them. Adherence to the breast cancer surveillance program for women at risk for familial breast and ovarian cancer versus overscreening-a monocenter study in Germany.

Exploring perceptions of cancer risk, neighborhood environmental risks, and health behaviors of blacks

Cancer risk perceptions and cancer worry are shaped by race/ethnicity, and social, economic, and environmental factors, which in turn shape health decision-making. A paucity of studies has explored risk perceptions and worry in metropolitan areas with disparate environmental conditions and cancer outcomes. This study examined perceptions of cancer risk, neighborhood environmental health risks, and risk-reducing health behaviors among Blacks. A 59-item survey was administered to respondents in Metropolitan Charleston, South Carolina from March to September 2013. A convenience sample of males and females was recruited at local venues and community events. Descriptive statistics, bivariate analyses (Chi square tests), and logistic regression models were estimated using SAS 9.3 software. Respondents (N = 405) were 100% Black, 81% female (n = 323), and ranged from 18 to 87 years of age (M = 49.55, SD = 15.27). Most respondents reported lower perceptions of cancer risk (37%) and equated their cancer beliefs to direct or indirect (i.e. personal or family) experiences. Low perceived cancer risk (absolute risk) was significantly associated (p < .05) with non-alcohol consumption, having a colon cancer screening test, being female, and being age 25-44 or 45-64. Cancer worry was significantly associated (p < .05) with being a current smoker, having a "fair" diet, non-alcohol consumption, and having any colon cancer screening test. Perceived cancer risk is an important indicator of health behaviors among Blacks. Direct or indirect experiences with cancer and/or the environment and awareness of family history of cancer may explain cancer risk perceptions.

Genetic Testing and Post-Testing Decision Making among BRCA-Positive Mutation Women: A Psychosocial Approach

Through an analysis of an online survey of women who tested positive for the BRCA genetic mutation for breast cancer, this research uses a social constructionist and feminist standpoint lens to understand the decision-making process that leads BRCA-positive women to choose genetic testing. Additionally, this research examines how they socially construct and understand their risk for developing breast cancer, as well as which treatment options they undergo post-testing. BRCA-positive women re-frame their statistical medical risk for developing cancer and their post-testing treatment choices through a broad psychosocial context of engagement that also includes their social networks. Important psychosocial factors drive women's medical decisions, such as individual feelings of guilt and vulnerability, and the degree of perceived social support. Women who felt guilty and fearful that they might pass the BRCA gene to their children were more likely to undergo risk reducing surgery. Women with at least one daughter and women without children were more inclined toward the risk reducing surgery compared to those with only sons. These psychosocial factors and social network engagements serve as a "nexus of decision making" that does not, for the most part, mirror the medical assessments of statistical odds for hereditary cancer development, nor the specific treatment protocols outlined by the medical establishment.

The Influence of Absolute and Comparative Risk Perceptions on Cervical Cancer Screening and the Mediating Role of Cancer Worry

This research investigates the interrelationships between cancer risk perceptions (absolute and comparative risk perceptions), cancer worry, and cervical cancer screening. Using a nationally representative survey data set (N = 2,304) from the 2012 Health Information National Trends Survey Circle 1, we found that although neither absolute risk perceptions nor comparative risk perceptions exerted a direct impact on women's compliance with the cervical cancer screening recommendation (i.e., that women ages 21 to 65 obtain Pap smear every 3 years; U.S. Preventive Services Task Force, 2012 ), both types of risk perceptions had an indirect effect on cervical cancer screening through the mediation of cancer worry. These results suggest a primal role of affect in health decision making. Implications of the findings for cancer risk communication are discussed.

Correlates of misperception of breast cancer risk among Korean-American Women

In this study, the authors investigate the factors associated with misperception of breast cancer risk, including unrealistic optimism and unrealistic pessimism, among Korean-American women (KAW). Baseline data were collected between March 2010 and October 2011 from 421 KAW aged 40-65 years who participated in a community-based randomized intervention trial designed to promote breast and cervical cancer screening. Multivariate multinomial regression was performed to identify correlates of misperception of breast cancer risk among KAW. A total of 210 KAW (49.9%) had breast cancer risk perception consistent with their objective risk, whereas 50.1% of KAW in the study had some form of misperception of risk. Specifically, 167 participants (39.7%) were unrealistically optimistic about their own breast cancer risk; 44 (10.5%) were unrealistically pessimistic. In multivariate multinomial logistic regression analysis, living with a partner and higher education were significantly associated with higher odds of having unrealistic optimism. High social support is associated with a lower likelihood of having a pessimistic risk perception. Higher worry is associated with a higher likelihood of having unrealistic pessimism. Misperception of breast cancer risk among KAW and related factors must be considered when developing behavioral interventions for this population.

Correlates of Cancer Information Overload: Focusing on Individual Ability and Motivation

The present study defined cancer information overload (CIO) as an aversive disposition wherein a person is confused and overwhelmed by cancer information, which occurs when he or she fails to effectively categorize new information due to a lack of resources for effective learning. Based on the definition and informed by previous studies on information overload and the cognitive mediation model, we hypothesized that low ability and motivation to process cancer information would lead to CIO. We used education level and trait anxiety as factors related to ability. Cancer history and the use of active media channels (such as the Internet and print media) were adopted as motivational factors. Four samples (three from the United States and one from South Korea) were used to explore the relationship between ability/motivation and CIO. Among them, only Sample 4 participants answered questions about stomach cancer, and other participants were asked about cancer in general. In all four samples, trait anxiety was positively associated with CIO. Health information use from active media channels (print or the Internet) was negatively associated with CIO in three samples. The associations between family history and CIO, and between education and CIO, were found in two samples. In short, the present study demonstrated that CIO partly depends on individual ability and motivation, thereby showing that CIO is influenced by personal characteristics as well as environmental factors.

Breast cancer risk assessment using the Gail model: a Turkish study

PURPOSE

This study was conducted to determine risk of developing of breast cancer among Turkish women.

MATERIALS AND METHODS

Using a descriptive and cross-sectional approach, data were collected from 231 women. Breast cancer risk was calculated using the National Cancer Institute's on-line verson of called as the Breast Cancer Risk Assessment Tool or the Gail Risk Assesment Tool.

RESULTS

The average age of women was 45.0±8.06 years. It was revealed that 6.1% of participants reported having first degree relatives who had had breast cancer, with only four women having more than one first-degree relative affected (1.7%). The mean five-year breast cancer risk for all women was 0.88±0.91%, and 7.4% of women had a five-year breast cancer risk >1.66% in this study. Mean lifetime breast cancer risk up to age 90 years was 9.3±5.2%.

CONCLUSIONS

The breast cancer risk assessment tool can help in the clinical management of patient seeking advice concerning screening and prevention. Healthcare providers in Turkey can use this approach to estimate an individual's probability of developing breast cancer.

Enhanced Tuberculosis Infection Treatment Outcomes after Implementation of QuantiFERON®-Gold Testing

Background

Use of the tuberculin skin test (TST) for diagnosis of latent tuberculosis infection (LTBI) among individuals who received the Bacille Calmette-Guérin (BCG) vaccine is complicated by its potential cross-reaction with TST antigens which may cause false-positive results and lead to patient and physician reluctance to initiate LTBI treatment. QuantiFERON®-TB Gold (QFT-G) lacks this cross-reaction. We sought to study the impact of implementing QFT-G testing in 2006 on LTBI treatment initiation and completion at NYC chest clinics.

Methods

QFT-G results from 10/2006–12/2008 in NYC Department of Health and Mental Hygiene chest clinics were obtained from the electronic medical record system. The proportions of patients who initiated and completed treatment among patients tested with QFT-G were compared to those tested with TST from 10/2004–9/2006.

Results

Among 36,167 patients tested with QFT-G, 2,300 (6%) tested positive, 33,327 (93%) tested negative, and 540 (1%) had an indeterminate result. Among those who had a positive QFT-G test and deemed eligible, 985 (80%) initiated LTBI treatment and 490 (40%) completed treatment. Historically, among patients tested with TST, 7,073 (19%) tested positive (p<0.0001 compared to QFT-G); 3,182 (79%) of those eligible initiated LTBI treatment and 1,210 (30%) completed treatment (p<0.0001 compared to QFT-G).

Conclusions

QFT-G implementation increased the proportion of patients completing LTBI treatment. Additional studies are needed in more settings to determine whether using QFT-G leads to a sustained increase in treatment completion.

Securing and Documenting Cancer Family History in the Age of the Electronic Medical Record

Family health history is one of the least expensive, most useful, and most underused methods available to conduct assessments of the genetic aspect of a condition or to target the need for a genetic evaluation. This article introduces to the surgical oncologist the reason and process of collecting family history information. As medical records shift from paper to electronic formats, pedigree drawings are not readily available within the electronic health records. International efforts are underway to develop searchable, updatable, and interoperable formats that can collect family history information to inform clinical decision support for genetic risk assessment.

Differences in health beliefs across stage of adoption of mammography in Iranian women

BACKGROUND

Despite evidence that screening for breast cancer is effective, adherence with screening recommendations in Iranian women is low.

OBJECTIVES

The aims of this study were to (a) examine the relationships between related beliefs and (b) to determine to what extent women in stages of mammography adoption differ in their agreement of individual perceived health beliefs.

METHODS

A sample of 686 Iranian women completed a questionnaire including selected constructs of the Health Belief Model and stages of mammography adoption.

RESULTS

Proportions of participants who were in the preadoption and adoption stages were 75% and 17.8%, respectively. Precontemplators showed significantly lower positive attitude and greater agreement for most of the barrier items than did those in other adoption stages. In terms of specific items, women in the relapse and maintenance stages endorsed greatest agreement for the barrier items "not knowing how to get a mammogram" and "forget to schedule," respectively. Common barriers for women in preadoption stages were being painful, taking much time, and embarrassing.

CONCLUSION

Iranian women are less likely than other Asian women to be in the maintenance and action stages. Identifying the associations between perceived related beliefs items and stages of mammography adoption may provide detailed information to allow for future research and guide the development of interventions not only for Iranian women but also for similar cultural and immigrant groups that have been neglected to date in the breast cancer literature.

IMPLICATIONS FOR PRACTICE

Examining the interactions between perceived related beliefs items and other beliefs such as perceived control and self-efficacy to having a mammography is warranted.

Health care utilization, lifestyle, and emotional factors and mammography practices in the Childhood Cancer Survivor Study

BACKGROUND

Women with a history of chest radiotherapy have an increased risk of breast cancer; however, many do not undergo annual recommended screening mammography. We sought to characterize the relationship between mammography and potentially modifiable factors, with the goal of identifying targets for intervention to improve utilization.

METHODS

Of 625 female participants sampled from the Childhood Cancer Survivor Study, who were treated with chest radiotherapy, 551 responded to a survey about breast cancer screening practices. We used multivariate Poisson regression to assess several lifestyle and emotional factors, health care practices, and perceived breast cancer risk, in relation to reporting a screening mammogram within the last two years.

RESULTS

Women who had a Papanicolaou test [prevalence ratio (PR): 1.77; 95% confidence interval (CI) 1.26-2.49], and who perceived their breast cancer risk as higher than the average woman were more likely to have had a mammogram (PR, 1.26; 95% CI, 1.09-1.46). We detected an attenuated effect of echocardiogram screening [PR, 0.70; 95% CI (0.52-0.95)] on having a mammogram among older women compared with younger women. Smoking, obesity, physical activity, coping, and symptoms of depression and somatization were not associated with mammographic screening.

CONCLUSION

Our findings suggest that compliance with routine and risk-based screening can be an important indicator of mammography in childhood cancer survivors. In addition, there is a need to ensure women understand their increased breast cancer risk, as a means to encouraging them to follow breast surveillance guidelines.

IMPACT

Screening encounters could be used to promote mammography compliance in this population.

A Three-Factor Cancer-Related Mental Condition Model and Its Relationship With Cancer Information Use, Cancer Information Avoidance, and Screening Intention

Cancer-related affect and cognition, such as cancer fear, cancer worry, and cancer risk perception, are important predictors of cancer prevention and communication behaviors. However, they have not been clearly conceptualized in cancer communication literature, and in particular, the role of affect (i.e., cancer fear) in cancer prevention and communication has not been fully investigated. The present study developed a 3-factor cancer-related mental condition model encompassing affective (cancer fear), cognitive (cancer risk perception), and affective-cognitive (cancer worry) conditions. Two studies were conducted. Study 1 developed the model with Sample 1 (U.S. undergraduates, N = 309), and subsequently validated the model with Sample 2 (Korean general population, ages 40 years or older, N = 1,130). Study 2, using Sample 2, tested the model's relationship with cancer information use, cancer information avoidance, and screening intention. While Sample 1 participants were asked about cancer in general, Sample 2 participants were asked specifically about stomach cancer. Thus, the model derived from the specific sample in a general context was confirmed via the general sample in a specific context. The results showed that both cancer worry and cancer risk perception are positively associated with cancer information use and screening intention, but they are negatively associated with cancer information avoidance. Cancer fear was positively associated with cancer information use, but it was also positively related to cancer information avoidance. Moreover, cancer fear was negatively associated with screening intention. Although the three components of the model are positively related to one another, they function differently in the cancer context.

Breast Cancer Risk Assessment Among Low-Income Women of Color in Primary Care: A Pilot Study

PURPOSE

The US Preventive Services Task Force recommends identifying candidates for breast cancer (BC) chemoprevention and referring them for genetic counseling as part of routine care. Little is known about the feasibility of implementing these recommendations or how low-income women of color might respond to individualized risk assessment (IRA) performed by primary care providers (PCPs).

METHODS

Women recruited from a federally qualified health center were given the option to discuss BC risk status with their PCP. Comprehensive IRA was performed using a software tool designed for the primary care environment combining three assessment instruments and providing risk-adapted recommendations for screening, prevention, and genetic referral. Logistic regression models assessed factors associated with wanting to learn and discuss BC risk with PCP.

RESULTS

Of 237 participants, only 12.7% (n = 30) did not want to discuss IRA results with their PCP. Factors associated with lower odds of wanting to learn results included having private insurance and reporting ever having had a mammogram. Factors associated with higher odds of wanting to learn results included older age (50 to 69 years) and increased BC worry. For all women wishing to learn results, IRA was successfully completed and delivered to the PCP immediately before the encounter for incorporation into the well-visit evaluation.

CONCLUSION

Incorporation of US Preventive Services Task Force recommendations as part of routine primary care is feasible. Interest in IRA seems high among underserved women. This approach warrants further investigation as a strategy for addressing disparities in BC mortality.

Moderating effects of media exposure on associations between socioeconomic position and cancer worry

Reducing fear of cancer is significant in developing cancer screening interventions, but the levels of fear may vary depending on the degrees of media exposure as well as individuals' socioeconomic positions (SEP). However, few studies have examined how the SEP influences the fear of cancer under the moderating process of general and specific forms of media exposure. We investigated the moderating effect of media exposure on the relationship between SEP and the level of fear of cancer by assuming that cancer knowledge is a covariate between those two. In particular, this study examined how exposure to both general and specific media changes the series of processes from SEP to fear of cancer. We conducted path analyses with three types of media--television, radio and the Internet--using data from a health communication survey of 613 adults in Massachusetts in the United States. We found that SEP influences cancer knowledge directly and fear of cancer indirectly, as moderated by the level of media exposure. Health-specific exposure, however, had a more consistent effect than general media exposure in lowering the fear of cancer by increasing knowledge about cancer. A higher level of health-specific exposure and greater amount of cancer knowledge lessened the fear of cancer. In addition, the more people were exposed to health information on television and the Internet, the lower the level of fear of cancer as a result. These findings indicate a relationship between SEP and fear of cancer, as moderated by the level and type of media exposure. Furthermore, the findings suggest that for early detection or cancer prevention strategies, health communication approaches through mass media need to be considered.

Psychosocial Factors Associated With Risk Perceptions for Chronic Diseases in Younger and Middle-Aged Women

Perceptions of disease risk play an important role in motivating people to adopt healthy behaviors. However, little is known about psychosocial factors that influence women's perceived risk for developing disease. The present study investigated the extent to which individual traits, social influences, objective risk factors, and demographic characteristics were associated with women's risk perceptions for cardiovascular disease, breast cancer, and lung cancer. Using structural equation modeling, we examined hypothesized associations among 452 younger (ages 18-25 years) and 167 middle-aged (ages 40-64 years) women. A greater number and variety of factors were associated with middle-aged women's risk perceptions compared to younger women. For both groups, some objective risk factors were associated with risk perceptions; yet, associations also existed between multiple psychosocial variables (optimism, health locus of control, social exposure to disease, perceived stigma) and risk perceptions. Results suggested that women may base their risk estimates on factors beyond those considered important by healthcare providers.
