Health Literacy Interventions in Cancer: a Systematic Review

Approximately one-third of adults in the United States (U.S.) have limited health literacy. Those with limited health literacy often have difficultly navigating the health care environment, including navigating care across the cancer continuum (e.g., prevention, screening, diagnosis, treatment). Evidence-based interventions to assist adults with limited health literacy improve health outcomes; however, little is known about health literacy interventions in the context of cancer and their impact on cancer-specific health outcomes. The purpose of this review was to identify and characterize the literature on health literacy interventions across the cancer care continuum. Specifically, our aim was to review the strength of evidence, outcomes assessed, and intervention modalities within the existing literature reporting health literacy interventions in cancer. Our search yielded 1036 records (prevention/screening n = 174; diagnosis/treatment n = 862). Following deduplication and review for inclusion criteria, we analyzed 87 records of intervention studies reporting health literacy outcomes, including 45 pilot studies (prevention/screening n = 24; diagnosis/treatment n = 21) and 42 randomized controlled trials or quasi-experimental trials (prevention/screening n = 31; diagnosis/treatment n = 11). This literature included 36 unique interventions (prevention/screening n = 28; diagnosis/treatment n = 8), mostly in the formative stages of intervention development, with few assessments of evidence-based interventions. These gaps in the literature necessitate further research in the development and implementation of evidence-based health literacy interventions to improve cancer outcomes.

Dense Breast Notification Laws' Association With Outcomes in the US Population: A Cross-Sectional Study

OBJECTIVE

Understanding whether states' breast density notifications are associated with desired effects, or disparities, can inform federal policy. We examined self-reported receipt of personal breast density information, breast density discussions with providers, knowledge about density's masking effect, and association with increased breast cancer risk by state legislation status and women's sociodemographic characteristics.

METHODS

Cross-sectional observational population-based telephone survey of women aged >40 years who underwent mammography within prior 2 years, had no history of breast cancer, and had heard the term "breast density."

RESULTS

Among 2,306 women, 57% received personal breast density information. Multivariate regression models adjusted for covariates indicated that women in notification states were 1.5 times more likely to receive density information, and older Black and Asian women of lower income and lower health literacy were less likely. Overall, only 39% of women discussed density with providers; women in notification states were 1.75 times as likely. Older and Asian women were less likely to have spoken with providers; women with high literacy or prior biopsy were more likely. State legislation status was not associated with differences in density knowledge, but Hispanic women and women of lower income or low health literacy had less knowledge regarding density's masking effects; older women were more knowledgeable. Hispanic women and women of lower income or low health literacy were more likely, and middle-aged women less likely, to recognize increased breast cancer risk.

DISCUSSION

Some positive effects were observed, but sociodemographic disparities suggest tailoring of future breast density communications for specific populations of women to ensure equitable understanding.

Postpartum Analgesia in New Mothers (PAIN) Study: A Survey of Canadian Obstetricians' Post-Delivery Opioid-Prescribing Practices

OBJECTIVE

We aimed to describe opioid prescribing practices after obstetric delivery and to evaluate how these practices compare with national opioid prescribing guidelines.

METHODS

A closed survey was developed, evaluated for validity and reliability, and distributed by email to obstetrician members of the Society of Obstetricians and Gynaecologists of Canada (SOGC) in December 2018. Descriptive statistics were used to summarize respondent demographics, pharmaceutical pain management strategies, and opioid prescribing practices. Logistic regression was used to measure associations between respondent characteristics and high-risk opioid prescribing practices (e.g., prescribing >50 mg morphine equivalent dose per day, prescribing >5 days, not screening for substance/opioid use disorder before prescribing).

RESULTS

Our survey had high content validity (content validity index 0.89; 95% CI 0.78-1.00) and adequate reliability (Kappa 0.70; 95% CI 0.63-0.84 and intraclass correlation coefficient 0.70; 95% CI 0.67-0.81). Of the 1019 SOGC members reached, 243 initiated the survey (response rate, 24%). Among respondents, 235 (92%) completed the survey. Among opioid prescribers, 47% reported at least 1 high-risk opioid prescribing practice, the most frequent being a lack of substance/opioid use disorder screening. In the adjusted logistic regression model, being in practice more than 20 years (adjusted odds ratio [aOR] 0.53; 95% CI 0.29-0.93) and practising in a non-central area of Canada (aOR 0.49; 95% CI 0.28-0.84) reduced the odds of high-risk prescribing.

CONCLUSION

Further research on barriers to screening are needed to support and enhance safer opioid prescribing practices among Canadian obstetricians.

Discussions of Potential Mammography Benefits and Harms among Patients with Limited Health Literacy and Providers: "Oh, There are Harms?"

Starting breast cancer screening at age 40 versus 50 may increase potential harms frequency with a small mortality benefit. Younger women's screening decisions, therefore, may be complex. Shared decision-making (SDM) is recommended for women under 50 and may support women under 55 for whom guidelines vary. How women with limited health literacy (LHL) approach breast cancer screening decision-making is less understood, and most SDM tools are not designed with their input. This phenomenological study sought to characterize mammography counseling experiences among women with LHL and primary care providers (PCPs). Women ages 40-54 with LHL who had no history of breast cancer or mammogram within 9 months were approached before a primary care visit at a safety-net hospital. PCPs at this site were invited to participate. Qualitative interviews explored mammography counseling experiences. Patients also reviewed sample information materials. A constant comparison technique generated four themes salient to 25 patients and 20 PCPs: addressing family history versus comprehensive risk assessment; potential mammography harms discussions; information delivery preferences; and integrating pre-visit information tools. Findings suggest that current counseling techniques may not be responsive to patient-identified needs. Opportunities exist to improve how mammography information is shared and increase accessibility across the health literacy spectrum.

Abstract PO-079: Mixed success and persistent disparities in outcomes related to breast density legislation: A national survey

Little is known about whether women residing in states with mandated dense breast notification (DBN) have improved awareness, knowledge, or discussion with their doctors, or whether there are disparities by sociodemographic characteristics. We conducted a cross-sectional, national telephone survey to assess the primary outcomes intended by DBN legislation: informing women about personal breast density, increasing awareness of its making effect and association with increased cancer risk, and prompting discussions with providers. Specific efforts were made to include women from all race/ethnic groups, education strata, and literacy levels.

Women aged >40 reporting a mammogram in <2 years, with no prior breast cancer diagnosis and having heard of the term ‘breast density’ were eligible. We conducted chi-square analyses for each outcome, comparing each by state DBN legislation status, age, income, race/ethnicity, health literacy, and two clinical breast cancer risk factors (family history, prior breast biopsy). Paired comparisons within each sociodemographic factor were tested using Z-tests (α=0.05). Multivariable, binary logistic regressions predicted each outcome using all variables above entered simultaneously as predictors. Secondary analyses tested whether sociodemographic differences in outcomes were moderated by state DBN status via interaction terms. The sample included 2,306 women; 1,782 residing in DBN states and 524 in non-DBN states. Half of the participants were white (50.3%), 23.1% non-Hispanic black, 14% Hispanic, 8.2% Asian, and 4.4% ‘other’. Women in DBN states were 1.55 (95% CI = 1.20, 1.99) times more likely to have received personal breast density information compared to women in non-DBN states after controlling for sociodemographic and risk factors. Those with lower incomes, Asian women, and those with lower health literacy were less likely to report receiving personal breast density information.

Overall, 39% had a discussion with their provider about breast density, with women in DBN states being 1.82 times more likely to have done so (95% CI= 1.40, 2.37).

There were no differences between women in DBN vs. non-DBN states related to knowledge of masking bias (OR=.99, 0.71, 1.39) or understanding that breast density is a cancer risk factor (OR=0.93, 0.71, 1.22). Hispanic and lower income women had less knowledge about these topics. Interaction models failed to reveal moderating effects of state DBN status, indicating that DBN legislation does not appear to be mitigating or worsening the observed sociodemographic differences. Findings suggest that mandated DBNs have had partial success informing women about their breast density. However, we saw few indications that DBNs increased knowledge and observed less knowledge among women with low income, racial/ethnic minority status and lower literacy. This ‘one size fits all’ policy approach to relaying breast density information appears to be inadequate in reducing disparities in breast density awareness and knowledge.

Abstract PO-017: Using a Delphi panel to establish content for a breast cancer screening decision aid inclusive of women with limited health literacy

Breast cancer screening decision aids that help women understand their risk for cancer and available screening options can improve the quality of decision-making for women in their 40s, but existing decision aids do not address the needs of women with limited health literacy. We conducted a Delphi panel among breast cancer screening and decision science experts to determine content for a breast cancer screening decision aid for women ages 40-54 who have limited health literacy. Experts were those with an advanced degree (MD, PhD), at least 3 years of experience, and content expertise in breast cancer screening, health literacy, or decision aid design. Experts were invited via email to participate in an online Delphi panel, which aimed to establish consensus on decision aid content, guided by the International Patient Decision Aid Standards. Experts rated the importance of each item on a scale from 1 (not important) to 9 (very important), as well as how strong they felt the evidence was to support each. Open-ended responses explaining ratings were gathered, and in Round 1 experts were asked to nominate new items for inclusion. Following RAND methods, the 30th - 70th percentile range, central point, and asymmetry index were calculated for each item. From these values, a disagreement index was determined, and if the value was >1, indicating disagreement, the item was moved to the next round. Otherwise, consensus was established, and the item was omitted from future rounds. Between rounds, experts received a summary of their rating for each item relative to others, along with a summary of the open-ended explanations. The process was repeated for Rounds 2 and 3. 15 experts were invited, 9 agreed and 8 completed Round 1. All eight participants were female, with an average age of 53. Seven were white and 2 Asian. Five held medical doctorate degrees, 3 had PhDs. Seven experts completed all 3 rounds. Round 1 included 55 items, 30 of which obtained consensus (disagreement index < 1). 29 items were reviewed in Round 2 (25 from Round 1, plus 4 newly nominated items), 15 of which obtained consensus, leaving a final round of 14 items. In Round 3, 1 item achieved consensus, 4 items converged around uncertainty, and 9 did not reach consensus. Experts disagreed or were uncertain on the importance of including breast cancer risk factors and whether a description of the multiple screening modalities available should be included. Explanations for these items described balancing an ethical imperative to provide information and avoid paternalism while limiting information extraneous to the decision. While guidelines suggest that the age of initiating mammography and modalities used should involve an assessment of risk of developing breast cancer, experts did not agree about the inclusion of risk factor or modality information in a breast cancer screening decision aid for women with limited health literacy. Balancing detail with simplicity remains a challenge in determining content for decision support tools that seek to include a range of literacy levels.

Disparities in precision medicine-Examining germline genetic counseling and testing patterns among men with prostate cancer

INTRODUCTION

This study sought to examine whether germline genetic counseling and testing were employed differentially among men with prostate cancer by race and/or ethnicity and other social factors.

METHODS

In this retrospective analysis, all patients with prostate cancer listed as a visit diagnosis during the study period (April 2011 to August 2020) were identified from electronic health records. Patient characteristics were collected along with genetic counselor visits and germline genetic testing results in electronic health records. Multivariable analyses were performed with the primary outcome defined as the receipt of a genetic counseling visit and receipt of genetic testing.

RESULTS

A total of 14,610 patients with a prostate cancer diagnosis code were identified. The majority of patients were White (72%), aged >=65 years (62.7%), English-speaking (95%), married (71.4%), and publicly insured (58.7%). A total of 667 patients completed an appointment with a genetic counselor. A total of 439 patients received germline genetic test result, of whom 403 (91.8%) had also completed an appointment with a genetic counselor. Patients that were 65 years or older (adjusted odds ratio 0.53, 95%CI 0.44-0.65) and non-English proficient (adjusted odds ratio 0.71, 95%CI 0.42-1.21) were less likely to receive genetic counseling. Receiving genetic counseling was the strongest independent predictor of receipt of genetic testing.

CONCLUSIONS

The results of the current study highlight that the role of social factors in contributing to disparities in genetic counseling and testing among men with prostate cancer. These results underscore the importance of developing novel strategies to tackle contributors of observed disparities including language, age, and insurance status.

Health Literacy, Language, and Cancer-Related Needs in the First 6 Months After a Breast Cancer Diagnosis

PURPOSE

Low health literacy (HL) and language negatively affect cancer screening and prevention behaviors; less is known about how they affect the patient's experience during cancer treatment. This study explores associations among HL, spoken language, and dimensions of cancer-related needs within 6 months of receiving a breast cancer diagnosis.

METHODS

Women speaking English, Spanish, or Haitian Creole, enrolled in a patient navigation study at diagnosis, completed a survey in their primary spoken language at baseline and 6 months to characterize their cancer-related needs. HL was measured using the Brief Health Literacy Screening Tool. Outcomes included the Cancer Needs Distress Inventory (CaNDI; n = 38 items) and the Communication and Attitudinal Self-Efficacy scale (CASE-Cancer) for cancer (n = 12 items). Linear regressions measured the impact of HL and language on total CaNDI and CASE-Cancer scale for cancer scores and subscales, adjusted for demographics.

RESULTS

At baseline, 262 women participated and 228 (87%) followed up at 6 months. Of these, 38% had adequate HL, 33% had marginal HL, and 29% had inadequate HL. Women with inadequate or marginal HL had higher median baseline CaNDI scores (P = .02) and lower self-efficacy scores (P = .008), relative to those with adequate HL. Haitian-Creole speakers had significantly lower CANDI scores at baseline (P = .03). Adjusting for demographics, differences in CaNDI scores at baseline remained significant for those with lower HL and Haitian-Creole speakers. At 6 months, differences in self-efficacy persisted for Haitian-Creole speakers.

CONCLUSION

Findings suggest that interventions oriented to mitigating HL and language barriers might reduce distress at the time of diagnosis and improve self-efficacy over the course of treatment.

Exploring Explanatory Models of Risk in Breast Cancer Risk Counseling Discussions: NSABP/NRG Oncology Decision-Making Project 1

BACKGROUND

Explanatory models represent patient understanding of etiology, pathophysiology, illness, symptoms, and treatments, but little attention has been paid to how they are used by patients "at risk" for future disease.

OBJECTIVE

The aims of this study were to elucidate what constitutes an explanatory model of risk and to describe explanatory models of risk related to developing breast cancer.

METHODS

Thirty qualitative interviews with women identified as at an increased risk for breast cancer were conducted. Interviews were coded to identify domains of explanatory models of risk using a priori codes derived from the explanatory model of illness framework. Within each domain, a grounded thematic analysis described participants' explanatory models related to breast cancer risk.

RESULTS

The domains of treatment and etiology remained similar in a risk context compared with illness, whereas course of illness, symptoms, and pathophysiology differed. We identified a new, integrative concept relative to other domains within explanatory models of risk: social comparisons, which was dominant in risk perhaps due to the lack of physical experiences associated with being "at risk."

CONCLUSIONS

Developing inclusive understandings of risk and its treatment is key to developing a framework for the care of high-risk patients that is both evidence based and sensitive to patient preferences.

IMPLICATIONS FOR PRACTICE

The concept of "social comparisons" can assist healthcare providers in understanding women's decision making under conditions of risk. Ensuring that healthcare providers understand patient perceptions of risk is important because it relates to patient decision making, particularly due to an increasing focus on risk assessment in cancer.

Understanding Decision Making about Breast Cancer Prevention in Action: The Intersection of Perceived Risk, Perceived Control, and Social Context: NRG Oncology/NSABP DMP-1

BACKGROUND

Literature on decision making about breast cancer prevention focuses on individual perceptions and attitudes that predict chemoprevention use, rather than the process by which women decide whether to take risk-reducing medications. This secondary analysis aimed to understand how women's perceptions of breast cancer risk and locus of control influence their decision making.

METHODS

Women were accrued as part of the NRG Oncology/National Surgical Adjuvant Breast and Bowel Project Decision-Making Project 1, a study aimed at understanding contributors to chemoprevention uptake. Thirty women participated in qualitative in-depth interviews after being counseled about chemoprevention. Deductive codes grouped women based on dimensions of risk perception and locus of control. We used a constant comparative method to make connections among inductive themes focused on decision making, deductive codes for perceived risk and perceived locus of control, and the influence of explanatory models within and across participants.

RESULTS

Participants were predominantly non-Hispanic white (63%), with an average age of 50.9 years. Decision making varied across groups: the high-perceived risk/high-perceived control group used "social evidence" to model the behaviors of others. High-perceived risk/low-perceived control women made decisions based on beliefs about treatment, rooted in the experiences of social contacts. The low-perceived risk/low-perceived control group interpreted signs of risk as part of the normal continuum of bodily changes in comparison to others. Low-perceived risk/high-perceived control women focused on maintaining a current healthy trajectory.

CONCLUSION

"Social evidence" plays an important role in the decision-making process that is distinct from emotional aspects. Attending to patients' perceptions of risk and control in conjunction with social context is key to caring for patients at high risk in a way that is evidence based and sensitive to patient preferences.

A Qualitative Study of Spanish-Speakers' Experience with Dense Breast Notifications in a Massachusetts Safety-Net Hospital

BACKGROUND

Legislation requiring mammography facilities to notify women if they have dense breast tissue found on mammography has been enacted in 34 US states. The impact of dense breast notifications (DBNs) on women with limited English proficiency (LEP) is unknown.

OBJECTIVE

This study sought to understand Spanish-speaking women's experience receiving DBNs in a Massachusetts safety-net hospital.

DESIGN

Eligible women completed one audio-recorded, semi-structured interview via telephone with a native Spanish-speaking research assistant trained in qualitative methods. Interviews were professionally transcribed verbatim and translated. The translation was verified by a third reviewer to ensure fidelity with audio recordings.

PARTICIPANTS

Nineteen Spanish-speaking women ages 40-74 who received mammography with a normal result and recalled receiving a DBN.

APPROACH

Using the verified English transcripts, we conducted a content analysis to identify women's perceptions and actions related to receiving the notification. A structured codebook was developed. Transcripts were independently coded and assessed for agreement with a modification of Cohen's kappa. Content codes were grouped to build themes related to women's perceptions and actions after receiving a DBN.

KEY RESULTS

Nineteen Spanish-speaking women completed interviews. Nine reported not receiving the notification in their native language. Four key themes emerged: (1) The novelty of breast density contributed to notification-induced confusion; (2) women misinterpreted key messages in the notification; (3) varied actions were taken to seek further information; and (4) women held unrealized expectations and preferences for follow-up.

CONCLUSIONS

Not having previous knowledge of breast density and receiving notifications in English contributed to confusion about its meaning and inaccurate interpretations of key messages by Spanish speakers. Tools that promote understanding should be leveraged in seeking equity in risk-based breast cancer screening for women with dense breasts.

Women's perceptions of dense breast notifications in a Massachusetts safety net hospital: "So what is that supposed to mean?"

OBJECTIVE

Currently, 30 US states mandate that radiologists notify women when dense breast tissue is found on mammography. Little is understood about how notifications are perceived by recipients. This qualitative study sought to understand how dense breast notifications (DBNs) impact women's perceptions and their participation in follow-up care.

METHODS

We assessed rates of DBN recall and conducted semi-structured telephone interviews with 30 English-speaking women ages 40 to 74 after receiving a DBN from a Massachusetts hospital. Content coding characterized women's recall of the notification content, perceptions of breast density, and planned or actual participation in follow-up care.

RESULTS

Most women (81%) recalled receiving a DBN, but few could recall specific content. Women described struggling to understand the meaning of breast density and created their own explanatory models of dense breasts that differed from medical explanations. Many women planned to or did talk with their doctors about breast density as a result of receiving the notification.

CONCLUSIONS

Women receiving DBNs have limited knowledge and many misperceptions about the implications of having dense breasts.

PRACTICE IMPLICATIONS

Educational support is needed to promote informed decision- making about breast cancer screening that incorporates personal risk in the setting of dense breast legislation.

False-positive mammography and its association with health service use

OBJECTIVES

A false-positive mammogram can result in anxiety, distress, and increased perceptions of breast cancer risk, potentially changing how women utilize healthcare. This study examined whether having an abnormal mammogram, considered a proxy for elevated risk perception, was associated with greater future health service use (outpatient visits and referrals).

STUDY DESIGN

A retrospective cohort study using electronic health record data, spanning 2008 to 2012, from Boston Medical Center, a safety-net hospital.

METHODS

We grouped 3920 women aged 40 to 75 years receiving primary care and who had a mammogram between 2010 and 2011 into 3 categories: false-positive mammogram at index date; previous false positive, but normal index mammogram; and no history of false-positive mammograms. We contrasted the longitudinal changes in outpatient visits and provider referrals, before versus after the index mammogram, between women with false-positive mammogram and those without using Poisson regression models with a difference-in-differences specification. Clinical, visit, and demographic data were obtained from the institutional clinical data warehouse.

RESULTS

Adjusting for baseline differences in sociodemographic characteristics across risk groups and for secular changes between pre- and postindex periods, a current false-positive mammogram was associated with an 18% increase in overall outpatient visits (incidence rate ratio [IRR], 1.18; 95% CI, 1.07-1.51), but no corresponding increase in provider referrals (IRR, 1.15; 95% CI, 0.99‑1.34), relative to never having a false positive. A previous false-positive mammogram had no associated change in outpatient utilization (IRR, 0.99; 95% CI, 0.91-1.07).

CONCLUSIONS

Providers should discuss the implications of mammography findings at the time of screening to help mitigate potential detrimental effects and promote appropriate engagement in health services.

Primary Care Provider Experience with Breast Density Legislation in Massachusetts

BACKGROUND

Dense breasts on mammography independently increases breast cancer risk and decreases mammography sensitivity. Thirty-two states have adopted notification laws to raise awareness among women with dense breasts about supplemental screening. Little is known about these policies' impact on clinical practice among primary care providers (PCPs).

MATERIALS AND METHODS

This study explores PCP attitudes, knowledge, and the impact of the Massachusetts dense breast notification legislation on clinical practice after its enactment in 2015. An anonymous, online survey at two urban safety-net hospitals was administered in 2015-2016. Practicing MDs and nurse practitioners in primary care were invited to participate.

RESULTS

All 145 PCPs in general internal medicine at the two sites were e-mailed a survey link and 80 (55%) were completed. While 64 of 80 PCPs surveyed (80%) had some familiarity with the legislation, none identified the 8 required components of notifications contained in the Massachusetts legislation. Forty-nine percent (39/80) did not feel prepared to respond to patient questions about dense breasts. Forty-one percent (33/80) correctly identified that no current guidelines recommend the use of supplemental screening tests solely based on breast density and 85% (68/80) indicated interest in further training. Female and less experienced providers were more likely to be in favor of the legislation (49% vs. 11% by gender; 76% <5 years vs. 9%> 20 years). Women practitioners (55%) who were more likely than men (17%, p = 0.01) to agree with the policy changed their discussions of mammography results with patients.

CONCLUSIONS

PCPs feel underprepared to counsel women about breast density identified on mammography and its implications.

Deciding on breast cancer risk reduction: The role of counseling in individual decision-making - A qualitative study

OBJECTIVES

The presentation of risks and benefits in clinical practice is common particularly in situations in which treatment recommendations involve trade-offs. The treatment of breast cancer risk with selective estrogen receptor modulators (SERMs) is such a decision. We investigated the influence of health care provider (HCP) counseling on women's decision-making.

METHODS

Thirty breast cancer risk counseling sessions were recorded from April 2012-August 2013 at a comprehensive cancer center and at a safety-net, community hospital in the US. Participating women and HCPs were interviewed. A cross-case synthesis was used for analysis.

RESULTS

Of 30 participants 21 received a SERM-recommendation, 11 decided to take SERMs. Counseling impacted decision-making, but did not determine it. Three categories emerged: 1.) ability to change the decision anytime, 2.) perceptions on medications, and 3.) proximity of cancer.

CONCLUSION

Decision-making under conditions of a risk diagnosis such as increased breast cancer risk is a continuous process in which risk information is transformed into practical and experiential considerations.

PRACTICE IMPLICATIONS

Individuals' health care decision-making is only marginally dependent on the interactions in the clinic. Accepting patients' experiences and beliefs in their own right and letting them guide the discussion may be important for a satisfying decision-making process.

Explaining Breast Density Recommendations: An Introductory Workshop for Breast Health Providers

Introduction

High breast density is an independent risk factor for breast cancer and can decrease the sensitivity of mammography. However, evidence surrounding recommendations for patient risk stratification and supplemental screening is evolving, and providers receive limited training on breast density counseling.

Methods

We implemented an introductory, interactive workshop about breast density including current evidence behind supplemental screening and risk stratification. Designed for providers who counsel women on breast health, this workshop was evaluated with internal medicine providers, primary care residents, and radiology residents. We surveyed participants about knowledge and attitudes at baseline, postintervention (residents and providers), and 3-month follow-up (providers only). We compared baseline and postintervention scores and postintervention and 3-month follow-up scores using paired t tests and McNemar's tests.

Results

Internal medicine providers had significant gains in knowledge when comparing baseline to postintervention surveys (6.5-8.5 on a 10-point scale, p < .0001), with knowledge gains maintained when comparing postintervention to 3-month follow-up surveys (p = .06). Primary care and radiology residents also had significant gains in knowledge when comparing baseline to postintervention surveys (p < .004 for both). All learner groups reported increases in their confidence regarding counseling women about breast density and referring for supplemental screening.

Discussion

Through this breast density session, we showed trends for increased knowledge and change in attitudes for multiple learner groups. Because we aim to prepare providers with the best currently available recommendations, these materials will require frequent updating as breast density evidence and national consensus evolve.

Social Network Structures of Breast Cancer Patients and the Contributing Role of Patient Navigators

BACKGROUND

Minority women in the U.S. continue to experience inferior breast cancer outcomes compared with white women, in part due to delays in care delivery. Emerging cancer care delivery models like patient navigation focus on social barriers, but evidence demonstrating how these models increase social capital is lacking. This pilot study describes the social networks of newly diagnosed breast cancer patients and explores the contributing role of patient navigators.

MATERIALS AND METHODS

Twenty-five women completed a one hour interview about their social networks related to cancer care support. Network metrics identified important structural attributes and influential individuals. Bivariate associations between network metrics, type of network, and whether the network included a navigator were measured. Secondary analyses explored associations between network structures and clinical outcomes.

RESULTS

We identified three types of networks: kin-based, role and/or affect-based, or heterogeneous. Network metrics did not vary significantly by network type. There was a low prevalence of navigators included in the support networks (25%). Network density scores were significantly higher in those networks without a navigator. Network metrics were not predictive of clinical outcomes in multivariate models.

CONCLUSION

Patient navigators were not frequently included in support networks, but provided distinctive types of support. If navigators can identify patients with poorly integrated (less dense) social networks, or who have unmet tangible support needs, the intensity of navigation services could be tailored. Services and systems that address gaps and variations in patient social networks should be explored for their potential to reduce cancer health disparities.

IMPLICATIONS FOR PRACTICE

This study used a new method to identify the breadth and strength of social support following a diagnosis of breast cancer, especially examining the role of patient navigators in providing support. While navigators were only included in one quarter of patient support networks, they did provide essential supports to some individuals. Health care providers and systems need to better understand the contributions of social supports both within and outside of health care to design and tailor interventions that seek to reduce health care disparities and improve cancer outcomes.

Abstract B68: Explanatory models of risk: The role of social context in breast cancer risk perception and decision making

Background: The current practice of counseling high-risk breast cancer patients using probabilistic risk estimates has not proven to be effective in engaging women, with less than 1% of eligible women participating in medical interventions to reduce breast cancer risk. Further, studies show that racial and ethnic minority women are under-represented in breast cancer prevention clinical trials (Cyrus-David, 2006), and they are less likely than whites to be aware of, discuss, or take chemoprevention agents (Kaplan et al., 2006). This study seeks to describe how a diverse group of women use explanatory models of risk to describe perceptions of breast cancer risk and make decisions about risk-reducing behaviors.

Methods: 30 in-depth, qualitative interviews were collected at two US academic hospitals as part of a National Surgical Adjuvant Breast and Bowel Project mixed-methods study to oversample for racial and ethnic minorities. Women identified to have an elevated risk of developing breast cancer were interviewed following risk counseling with a medical provider. A thematic analysis informed by grounded theory methods was conducted. The explanatory model framework (Kleinman, 1978) guided formation of codes around explanatory model topic areas (etiology, symptoms, pathophysiology, course of illness, and treatment). These explanatory model codes were supplemented with inductive codes developed through open coding related to beliefs about cancer, risk, health, and social context.

Results: Two key themes were identified as closely linked to women's explanatory models of risk: ‘risk perception’ and ‘control over risk’. These perceptions of risk and control were used to identify patterns in how women chose to manage their risk for breast cancer. Whether women had high or low perceptions of risk and control affected the ways in which they used explanatory models to describe their decisions. For example, women with perceptions of high risk and high control all discussed their social network as influential in modeling how they could reduce their own risk. These women adopted a variety of behaviors to gain control over risk, ranging from diet and exercise changes to the use of chemoprevention agents. Conversely, women with perceptions of high risk and low control based decisions much more closely on their general explanatory models of health, falling back on established philosophies in their decision-making. Women who opted for chemoprevention agents in this group discussed their philosophy of decision making as dependent on physician recommendations.

How women interpreted ‘symptoms’ of risk was also essential to women's descriptions of their participation in risk-reduction behaviors. Those women who perceived their risk to be high interpreted symptoms such as ADH, ALH, or LCIS as a disease that required medical intervention. On the other hand, women with perceptions of low risk interpreted these symptoms as in the normal course of bodily changes, contrasting with information provided by physicians suggesting an increased risk for breast cancer.

Discussion: There are important differences in how women use explanatory models of risk that contribute to the adoption of medical interventions. Risk counseling must address patient explanatory models, which influence both perceptions of risk and control over risk. These perceptions subsequently influence the ways in which women describe their decisions about participating in risk-reducing behaviors. New approaches are needed to address patient beliefs and perceptions about risk and prevention for breast cancer. Failing to acknowledge the experiences of patients threatens to marginalize minority groups from preventive care.

Beliefs About Anal Cancer among HIV-Infected Women: Barriers and Motivators to Participation in Research

BACKGROUND

Infection with the human immunodeficiency virus (HIV) remains associated with a greater risk of anal cancer, despite widespread use of combination antiretroviral therapy. Evidence concerning the acceptability of anal cancer screening gives little attention to women. Because HIV-infected women have a high prevalence of depression and history of sexual trauma, understanding acceptability among this group is critical.

PURPOSE

We sought to assess barriers and motivators to participation in anal cancer screening research among a racial/ethnically diverse HIV-infected female population.

METHODS

We conducted a survey based on the Health Belief Model to identify characteristics of women willing to participate in anal cancer screening research (n = 200). Bivariate analyses examined associations between willingness to participate and sociodemographics, clinical characteristics, and health beliefs. Logistic regression modeled willingness to participate in research.

MAIN FINDINGS

Of the women who participated, 37% screened positive for depression, 43% reported a high trauma history, and 36% screened positive for posttraumatic stress disorder. Overall, 65% reported willingness to participate in research. Those likely to participate were older, reported intravenous drug use as their HIV risk factor, and had a history of prior high-resolution anoscopy (HRA) compared with those unwilling to participate. The most commonly reported barrier to anal Pap testing was fear of pain. In adjusted analyses, a lack of fear of pain and prior experience with HRA significantly predicted willingness to participate.

CONCLUSIONS

Findings suggest that, to increase participation in anal Pap and HRA-related research for HIV-infected women, a single approach may not be adequate. Rather, we must harness patients' previous experiences and address psychosocial and financial concerns to overcome barriers to participation.

Shared Decision Making and the Use of Screening Mammography in Women Younger Than 50 Years of Age

Current breast cancer screening guidelines promote the use of shared decision making for women younger than 50 years of age, yet their effect on mammography utilization is largely unknown. This study aimed to examine the effect of two elements of shared decision making on the use of mammogram screening: patient-perceived choice and patient-provider communication. Data were obtained from HINTS 4, a nationally representative survey of the U.S. population, administered from 2011 to 2013. Choice was measured with the question "Has a doctor ever told you that you could choose whether or not to have a mammogram?" Communication was measured using a 7-item scale (range: 7-28; higher scores denote better communication). Binary logistic regression models assessed the effect of patient choice and communication on ever having a mammogram using weighted sample data. The sample included 1,085 women younger than 50 years of age: 31% of women perceived having a choice to undergo mammography. The mean patient-provider communication score was 22.8. Those who thought they were given a choice regarding mammography were more likely to have a mammogram relative to those who did not think a choice was given by the provider. Patient-provider communication had no significant association with mammography utilization. Patient perceived choice, but not patient-provider communication, is positively associated with mammography utilization in women younger than 50 years of age.
