Abstract
OBJECTIVES A major strategy to reduce the impact of breast cancer (BC) among African Americans (AA) is patient navigation, defined here as individualized assistance for reducing barriers to healthcare use. The primary focus of this study was to estimate the added value of incorporating breast health promotion by navigated participants and the subsequent BC screenings that network members may obtain. METHODS In this study, we compared the cost-effectiveness of navigation across 2 scenarios. First, we examine the effect of navigation on AA participants (scenario 1). Second, we examine the effect of navigation on AA participants and their networks (scenario 2). We leverage data from multiple studies in South Chicago. Our primary outcome (BC screening) is intermediate, given limited available quantitative data on the long-term benefits of BC screening for AA populations. RESULTS When considering participant effects alone (scenario 1), the incremental cost-effectiveness ratio was $3845 per additional screening mammogram. When including participant and network effects (scenario 2), the incremental cost-effectiveness ratio was $1098 per additional screening mammogram. CONCLUSION Our findings suggest that inclusion of network effects can contribute to a more precise, comprehensive assessment of interventions for underserved communities.

Cancer Control 2022; 29:10732748221104666.

Abstract
Objectives Despite the benefits of genetic counseling and testing (GCT), utilization is
particularly low among African American (AA) women who exhibit breast cancer
features that are common in BRCA-associated cancer. Underutilization is
especially problematic for AA women who are more likely to die from breast
cancer than women from any other race or ethnicity. Due to medical mistrust,
fear, and stigma that can be associated with genetic services among
racial/ethnic minorities, reliance on trusted social networks may be an
impactful strategy to increase dissemination of knowledge about hereditary
cancer risk. Informed by the social cognitive theory, the purpose of this
study is to determine: 1) which AA patients diagnosed with breast cancer and
with identified hereditary risk are sharing information about hereditary
risk with their networks; 2) the nature of the information dissemination;
and 3) if personal GCT experiences is associated with dissemination of
information about hereditary risk. Methods Among consented participants (n = 100) that completed an interview
administered using a 202-item questionnaire consisting of open- and
closed-ended questions, 62 patients were identified to be at higher risk for
breast cancer. Descriptive statistics, bivariable chi-square, Pearson’s
exact tests, and regression analyses were conducted to examine differences
in characteristics between high-risk participants who disseminated
hereditary risk information and participants who did not. Results Among high-risk participants, 25 (40%) indicated they had disseminated
information about hereditary risk to at least one member in their
family/friend network and 37 (60%) had not. Receipt of both provider
recommendations and receipt of GCT services was associated with greater odds
of disseminating information about hereditary risk with networks, OR = 4.53,
95%CI [1.33, 15.50], p = .02. Conclusion Interventions that increase self-efficacy gained through additional
personalized knowledge and experience gained through provider
recommendations and by undergoing GCT may facilitate information
dissemination among social/familial networks.

Navigated African American breast cancer patients as incidental change agents in their family/friend networks. Support Care Cancer 2021; 30:2487-2496. [PMID: 34783907 DOI: 10.1007/s00520-021-06674-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2021] [Accepted: 11/01/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Patient navigation is an increasingly widespread intervention to address the persistent, severe, and disproportionate breast cancer (BC) burden that African Americans (AA) face. Navigation may have more widespread effects than previously estimated due to patient-driven diffusion of BC information. METHODS This pilot study examined the network effects of a randomized controlled trial via recruitment of navigated and non-navigated AA BC patients as well as their network members. We estimated study arm differences in patient BC promotion (i.e., number of individuals to whom BC patients promote BC screening) and network BC screening (i.e., % BC screening among network members). RESULTS Among our sample of 100 AA BC patients, navigated patients promoted BC screening to more individuals than non-navigated patients. BC patients were more likely to promote BC screening to children and individuals with whom they communicated more frequently. Some models further suggested more network BC screening among "navigated" network members relative to "non-navigated" network members. CONCLUSIONS Navigated AA patients promoted BC screening more widely throughout their networks than non-navigated AA BC patients. There were also suggestive findings regarding increased BC screening among their network members. Our pilot study highlights the potential for social network analysis to improve the precision of intervention effect estimates and to inform future innovations (e.g., integrating navigation and network-based interventions) with multilevel effects on cancer health disparities.

Understanding the relationship between positive and negative social support and the quality of life among African American breast cancer survivors. Support Care Cancer 2021; 29:5219-5226. [PMID: 33630156 PMCID: PMC8295223 DOI: 10.1007/s00520-021-06098-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 02/19/2021] [Indexed: 02/06/2023]
Abstract
PURPOSE Social support improves several quality of life (QOL) domains among African American breast cancer survivors. How different dimensions of social support are associated with QOL among African American breast cancer survivors may however differ from other populations. This study explores this hypothesis by examining associations of positive social support (supportive interactions that promote affection) and negative social support (non-supportive interactions wherein the provider of support may not have the best intended actions) with QOL among Chicago-based African American breast cancer survivors. METHODS Study participants were eligible if they (1) were identified as being an African American female, (2) were at least 18 years of age or older, and (3) were diagnosed with breast cancer during or after navigation was implemented at the study hospital. Participants completed validated questionnaires via telephone or in-person interviews. RESULTS Among our sample of 100 participants, positive support was associated with greater mental well-being in non-imputed (Std β=1.60, CI: 0.51, 2.69, p= 0.004) and imputed models (Std β= 1.67, CI: 0.68, 2.73, p=0.001). There was also a weaker inverse association with negative support and mental well-being when using non-imputed data (Std β=-0.82, CI:-1.65, 0.02, p= 0.05). CONCLUSIONS Our findings suggest that positive support, in particular, is highly influential for improving mental well-being among African American breast cancer survivors. Simultaneously, negative support appears to be an independent, albeit weaker, determinant of mental well-being.
