Time to Diagnostic Evaluation After Mammographic Screening in an Urban Setting

The Integration of Value Assessment and Social Network Methods for Breast Health Navigation Among African Americans

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.

Power and Privilege: A Critical Analysis of Interpersonal Communication in Health Care as a Guide for Oncology Patient Navigation in Breast Cancer Care

Despite advances in cancer care, inequalities in race, ethnicity, and social class in breast cancer outcomes still exist. Interpersonal communication is a critical piece to addressing health disparities and it is a core component of the oncology patient navigator role. While widely used, the concept of interpersonal communication is vague, understudied, and requires better clarification to promote equity in health communication. The aim of this article is to investigate the concept of interpersonal communication through a critical lens. Findings from this critical analysis identified a gap in the current literature addressing the intersections of race, gender, and social class.

Variations in pathways and resource use in follow-up after abnormal mammography screening: a nationwide register-based study

PURPOSE

Mammography screening reduces breast cancer mortality, but a successful screening programme depends on both high participation and a sufficient follow-up of abnormalities. This study investigated patterns of follow-up after abnormal screening mammography in Denmark, and whether the variation was associated with health care resource use.

METHODS

We included 19,458 women aged 50-69 years with an abnormal screening mammography during a 3-year period of 2014-2016. Women were followed until the end of 2018. Their follow-up pathway was categorized in terms of the timeliness, appropriateness (i.e. whether all recommended diagnostic tests were utilized), and the ratio of benign vs. malignant surgeries. Further, we estimated health care resource use including post-diagnostic imaging and surgery procedures.

RESULTS

Ninety-seven percent of women had a diagnostic follow-up test within 6 months and 94% of those had diagnostic procedures in accordance with the recommendations. The proportion with timely follow-up (i.e. within 1 month) was 83%, but varied significantly between administrative regions (p < 0.001), and also between women with a screen-detected cancer and those with a false-positive mammogram (87% vs. 81%, p < 0.001). The ratio between having a benign versus a malignant surgery was 1:8, but it varied depending on which tests were used for diagnosis. The average number of procedures was, generally, in accordance with the recommendations.

CONCLUSION

In most cases, follow-up after abnormal screening mammography followed national recommendations. We nevertheless found that this was not always the case in certain subgroups and administrative regions.

Real-world challenges for patients with breast cancer in sub-Saharan Africa: a retrospective observational study of access to care in Ghana, Kenya and Nigeria

OBJECTIVE

To evaluate medical resource utilisation and timeliness of access to specific aspects of a standard care pathway for breast cancer at tertiary centres in sub-Saharan Africa.

DESIGN

Data were retrospectively abstracted from records of patients with breast cancer treated within a prespecified 2-year period between 2014 and 2017. The study protocol was approved by local institutional review boards.

SETTING

Six tertiary care institutions in Ghana, Kenya and Nigeria were included.

PARTICIPANTS

Health records of 862 patients with breast cancer were analysed: 299 in Ghana; 314 in Kenya; and 249 in Nigeria.

INTERVENTIONS

As directed by the treating physician.

OUTCOME MEASURES

Parameters selected for evaluation included healthcare resource and use, medical procedure turnaround times and out-of-pocket (OOP) payment patterns.

RESULTS

Use of mammography or breast ultrasonography was <45% in all three countries. Across the three countries, 78%-88% of patients completed tests for hormone receptors and human epidermal growth factor receptor 2 (HER2). Most patients underwent mastectomy (64%-67%) or breast-conserving surgery (15%-26%). Turnaround times for key procedures, such as pathology, surgery and systemic therapy, ranged from 1 to 5 months. In Ghana and Nigeria, most patients (87%-93%) paid for diagnostic tests entirely OOP versus 30%-32% in Kenya. Similarly, proportions of patients paying OOP only for treatments were high: 45%-79% in Ghana, 8%-20% in Kenya and 72%-89% in Nigeria. Among patients receiving HER2-targeted therapy, the average number of cycles was five for those paying OOP only versus 14 for those with some insurance coverage.

CONCLUSIONS

Patients with breast cancer treated in tertiary facilities in sub-Saharan Africa lack access to timely diagnosis and modern systemic therapies. Most patients in Ghana and Nigeria bore the full cost of their healthcare and were more likely to be employed and have secondary or postsecondary education. Access to screening/diagnosis and appropriate care is likely to be substantively lower for the general population.

Time to diagnostic resolution after an uncertain screening mammogram in an underserved population

BACKGROUND

Screening mammography has reduced breast cancer-associated mortality worldwide. Approximately 10% of patients require further diagnostic testing after an uncertain screening mammogram (Breast imaging reporting and data system [BI-RADS] = 0), and time to diagnostic resolution varies after BI-RADS = 0 screening mammogram. There is little data about factors associated with diagnostic resolution in patients of Chinese origin ("Chinese") receiving care in the US.

METHODS

We performed a retrospective analysis to identify patterns of diagnostic resolution in an urban US hospital with a large population of Chinese patients. We evaluated whether location of primary care provider (PCP) impacted time to resolution among Chinese patients, hypothesizing that patients with a PCP outside of the hospital would have longer time to diagnostic resolution than those patients with a PCP within the institution.

RESULTS

Between 2015 and 2016, 368 patients at Tufts Medical Center (Tufts MC) had resulting BI-RADS = 0 after screening mammogram. The majority of patients (341/368, 93%) achieved diagnostic resolution with median time to resolution 27 days (Q1: 14, Q3: 40). Seven percent (27/368) never achieved resolution. Among those with diagnostic resolution, 10% of patients required >60 days to achieve resolution. Chinese origin, no previous breast cancer, subsidized insurance, and outside referring physician were associated with longer time to resolution in univariable analysis. In multivariable regression, after adjusting for age, insurance, marital status, and prior breast cancer, Chinese patients with Tufts MC PCP experienced timelier diagnostic resolution vs Chinese patients without a Tufts MC PCP (hazard ratio [HR] = 1.85, P = .02). Location of PCP did not impact time to resolution among non-Chinese patients.

CONCLUSION

We identified patterns of diagnostic resolution in an urban hospital with a large historically underserved population. We found that Chinese patients without integrated primary care within the institution are at risk for delayed diagnostic resolution. Future interventions need to target at-risk patients to prevent loss of follow-up after uncertain screening mammogram.

Culturally competent healthcare - A scoping review of strategies implemented in healthcare organizations and a model of culturally competent healthcare provision

Background

Culturally and linguistically diverse patients access healthcare services less than the host populations and are confronted with different barriers such as language barriers, legal restrictions or differences in health beliefs. In order to reduce these disparities, the promotion of cultural competence in healthcare organizations has been a political goal. This scoping review aims to collect components and strategies from evaluated interventions that provide culturally competent healthcare for culturally and linguistically diverse patients within healthcare organizations and to examine their effects on selected outcome measures. Thereafter, we aim to organize identified components into a model of culturally competent healthcare provisions.

Methods and findings

A systematic literature search was carried out using three databases (Pubmed, PsycINFO and Web of Science) to identify studies which have implemented and evaluated cultural competence interventions in healthcare facilities. PICO criteria were adapted to formulate the research question and to systematically choose relevant search terms. Sixty-seven studies implementing culturally competent healthcare interventions were included in the final synthesis. Identified strategies and components of culturally competent healthcare extracted from these studies were clustered into twenty categories, which were organized in four groups: Components of culturally competent healthcare–Individual level; Components of culturally competent healthcare–Organizational level; Strategies to implement culturally competent healthcare and Strategies to provide access to culturally competent healthcare. A model integrating the results is proposed. The overall effects on patient outcomes and utilization rates of identified components or strategies were positive but often small or not significant. Qualitative data suggest that components and strategies of culturally competent healthcare were appreciated by patients and providers.

Conclusion

This scoping review used a bottom-up approach to identify components and strategies of culturally competent healthcare interventions and synthesized the results in a model of culturally competent healthcare provision. Reported effects of single components or strategies are limited because most studies implemented a combination of different components and strategies simultaneously.

A Community-Based Outreach Navigator Approach to Establishing Partnerships for a Safety Net Mammography Screening Center

Washington, DC, has one of the highest incidence and mortality rates for breast cancer in the USA. Patient navigation coupled with informational and community resources are important strategies that assist patients' access and help them understand the complex world of cancer care. The Georgetown Lombardi Comprehensive Cancer Center's Capital Breast Care Center (CBCC) is a safety net mammography screening center that utilizes a community-based navigation program. In addition to providing assistance with coordination of clinical services, navigators at CBCC are integral in establishing intra-community partnerships to educate members of the community about breast cancer screening. The aim of this study was to detail the role of patient navigation at the CBCC, with an emphasis on community engagement and community-based partnerships. We describe the process by which CBCC established partnerships with multiple community organizations between 2004 and 2015 and analyzed data of women screened in relationship to the evolution of the patient navigation services. Application of the CBCC navigation model that integrates individual patient outreach with community engagement has yielded viable and lasting community partnerships that have resulted in an increase in mammography uptake, especially among medically underserved minority women.

Breast density in multiethnic women presenting for screening mammography

Data on ethnic variations in breast density are limited and often not inclusive of underrepresented minorities. As breast density is associated with elevated breast cancer risk, investigating racial and ethnic difference may elucidate the observed differences in breast cancer risk among different populations. We reviewed breast density from initial screening of women from the Capital Breast Care Center and Georgetown University Hospital from 2010 to 2014. Patient demographics including race, age at screening, education, menopausal status, and body mass index were abstracted. We recorded the BI-RADS density categories: (1) "fatty," (2) "scattered fibroglandular densities," (3) "heterogeneously dense," and (4) "extremely dense." Multivariable unconditional logistic regression was used to identify predictors of breast density. Density categorization was recorded for 2146 women over the 5-year period, comprising Blacks (n = 940), Hispanics (n = 893), and Whites (n = 314). Analysis of subject characteristics by breast density showed that high category is observed in younger, Hispanic, nulliparous, premenopausal, and nonobese women (t-test or chi-square test, P-values <.0001). Obese women are 70% less likely to have high density. Being Hispanic, premenopausal, and nonobese were predictive of high density on logistic regression. In this analysis of density distribution in a diverse sample, Hispanic women have the highest breast density, followed by Blacks and Whites. Unique in our findings is women who identify as Hispanic have the highest breast density and lower rates of obesity. Further investigation of the impact of obesity on breast density, especially in the understudied Hispanic group is needed.
