Can patient navigation improve receipt of recommended breast cancer care? Evidence from the National Patient Navigation Research Program

Patient Navigation in Cancer Treatment: A Systematic Review

PURPOSE OF REVIEW

Patient navigation promotes access to timely treatment of chronic diseases by eliminating barriers to care. Patient navigation programs have been well-established in improving screening rates and diagnostic resolution. This systematic review aimed to characterize the multifaceted role of patient navigators within the realm of cancer treatment.

RECENT FINDINGS

A comprehensive electronic literature review of PubMed and Embase databases was conducted to identify relevant studies investigating the role of patient navigators in cancer treatment from August 1, 2009 to March 27, 2023. Fifty-nine articles were included in this review. Amongst studies focused on cancer treatment initiation, 70% found a significant improvement in treatment initiation amongst patients who were enrolled in patient navigation programs, 71% of studies focused on treatment adherence demonstrated significant improvements in treatment adherence, 87% of studies investigating patient satisfaction showed significant benefits, and 81% of studies reported a positive impact of patient navigators on quality care indicators. Three palliative care studies found beneficial effects of patient navigation. Thirty-seven studies investigated disadvantaged populations, with 76% of them concluded that patient navigators made a positive impact during treatment. This systematic review provides compelling evidence supporting the value of patient navigation programs in cancer treatment. The findings suggest that patient navigation plays a crucial role in improving access to care and optimizing treatment outcomes, especially for disadvantaged cancer patients. Incorporating patient navigation into standard oncology practice can reduce disparities and improve the overall quality of cancer care.

Association Between Racial and Socioeconomic Disparities and Hospital Performance in Treatment and Outcomes for Patients with Colon Cancer

BACKGROUND

Disparities in colon cancer care and outcomes by race/ethnicity, socioeconomic status (SES), and insurance are well recognized; however, the extent to which inequalities are driven by patient factors versus variation in hospital performance remains unclear. We sought to compare disparities in care delivery and outcomes at low- and high-performing hospitals.

METHODS

We identified patients with stage I-III colon adenocarcinoma from the 2012-2017 National Cancer Database. Adequate lymphadenectomy and timely adjuvant chemotherapy administration defined hospital performance. Multilevel regression models evaluated disparities by race/ethnicity, SES, and insurance at the lowest- and highest-performance quartile hospitals.

RESULTS

Of 92,573 patients from 704 hospitals, 45,982 (49.7%) were treated at 404 low-performing hospitals and 46,591 (50.3%) were treated at 300 high-performing hospitals. Low-performing hospitals treated more non-Hispanic (NH) Black, Hispanic, low SES, and Medicaid patients (all p < 0.01). Among low-performing hospitals, patients with low versus high SES (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.82-0.92), and Medicare (OR 0.90, 95% CI 0.85-0.96) and Medicaid (OR 0.88, 95% CI 0.80-0.96) versus private insurance, had decreased odds of receiving high-quality care. At high-performing hospitals, NH Black versus NH White patients (OR 0.83, 95% CI 0.72-0.95) had decreased odds of receiving high-quality care. Low SES, Medicare, Medicaid, and uninsured patients had worse overall survival at low- and high-performing hospitals (all p < 0.01).

CONCLUSION

Disparities in receipt of high-quality colon cancer care occurred by SES and insurance at low-performing hospitals, and by race at high-performing hospitals. However, survival disparities by SES and insurance exist irrespective of hospital performance. Future steps include improving low-performing hospitals and identifying mechanisms affecting survival disparities.

Mapping the Postpartum Experience Through Obstetric Patient Navigation for Low-Income Individuals

Background: Although the postpartum period is an opportunity to address long-term health, fragmented care systems, inadequate attention to social needs, and a lack of structured transition to primary care threaten patient wellbeing, particularly for low-income individuals. Postpartum patient navigation is an emerging innovation to address these disparities. Methods: This mixed-methods analysis uses data from the first year of an ongoing randomized controlled trial to understand the needs of low-income postpartum individuals through 1 year of patient navigation. We designed standardized logs for navigators to record their services, tracking mode, content, intensity, and target of interactions. Navigators also completed semistructured interviews every 3 months regarding relationships with patients and care teams, care system gaps, and navigation process. Log data were categorized, quantified, and mapped temporally through 1 year postpartum. Qualitative data were analyzed using the constant comparative method. Results: Log data from 50 participants who received navigation revealed the most frequent needs related to health care access (45.4%), health and wellness (18.2%), patient-navigator relationship building (14.8%), parenting (13.6%), and social determinants of health (8.0%). Navigation activities included supporting physical and mental recovery, accomplishing health goals, connecting patients to primary and specialty care, preparing for health system utilization beyond navigation, and referring individuals to community resources. Participant needs fluctuated, yielding a dynamic timeline of the first postpartum year. Conclusion: Postpartum needs evolved throughout the year, requiring support from various teams. Navigation beyond the typical postpartum care window may be useful in mitigating health system barriers, and tracking patient needs may be useful in optimizing postpartum care.

Importance of Diversity, Equity, and Inclusion in the Hepatopancreatobiliary Workforce

Diversity is a catalyst for progress that prevents institutional stagnation and, by extension, averts descent to mediocrity. This review focuses on the available data concerning hepatopancreatobiliary (HPB) surgical workforce demographics and identifies evidence-based strategies that may enhance justice, equity, diversity, and inclusion for HPB surgeons and their patients. We report that the current United States HPB surgical workforce does not reflect the population it serves. We review data describing disparity-perpetuating hurdles confronting physicians from minority groups underrepresented in medicine at each stage of training. We further examine evidence showing widespread racial and socioeconomic disparities in HPB surgical care and review the effects of workforce diversity and physician-patient demographic concordance on healthcare outcomes. Evidence-based mitigators of structural racism and segregation are reviewed, including tailored interventions that can address social determinants of health toward the achievement of true excellence in HPB surgical care. Lastly, select evidence-based data driving surgical workforce solutions are reviewed, including intentional compensation plans, mentorship, and sponsorship.

Navigation programs to support community-dwelling individuals with life-limiting illness: determinants of implementation

BACKGROUND

As the Canadian population ages and the prevalence of chronic illnesses increases, delivering high-quality care to individuals with advanced life limiting illnesses becomes more challenging. Community-based navigation programs are a promising approach to address these challenges, but little is known about how these programs are successfully implemented to meet the needs of this population. This study sought to identify the key determinants that contribute to the successful implementation of these programs within Canada.

METHODS

A qualitative study was undertaken to understand the implementation of eleven innovative, community-based navigation programs that aim to address the needs of individuals with life-limiting illnesses as they approach the end of life. The Consolidated Framework for Implementation Research (CFIR) guided the study design. Key informants (n = 23) within these programs took part in semi-structured interviews where they were asked to discuss how these programs are implemented. Data were analyzed using techniques employed in qualitative description.

RESULTS

We identified key determinants of successful implementation within each CFIR domain. In the outer setting domain, participants emphasized the importance of filling gaps in care to meet client needs, developing strong relationships with clients and community-based organizations, and navigating relationships with healthcare providers. At the inner setting level, leadership support, staff compatibility, and available resources were identified as important factors. In terms of intervention characteristics, the ability to adapt was cited as a facilitator, whereas costs were identified as a barrier. For the characteristics of individuals, participants described the importance of having staff whose values align with the program, and who have the experience and skills necessary to work with complex clients. Finally, having strong champions and evaluation processes were highlighted as important process-oriented determinants of successful implementation.

CONCLUSION

This study provides valuable insights into the determinants of successful implementation of community-based navigation programs in Canada. Understanding these determinants can guide the future development and integration of navigation programs to successfully meet the needs of those with life-limiting illnesses.

Breast cancer patient experiences in the Botswana health system: Is it time for patient navigators?

BACKGROUND

New models of care are required to support women with breast cancer due to rising incidence and mortality in sub-Saharan Africa (SSA). This study gives voice to the experiences of advanced-stage breast cancer patients in the Botswana healthcare system, to guide improved service provision and the potential utility of patient navigator (PN) programs.

METHODS

focus group discussions (FGD) were conducted with advanced-stage breast cancer patients recruited from the oncology ward of the public Princess Marina Hospital located in Gaborone, Botswana.

RESULTS

FGDs included 7 female breast cancer patients and their 7 caregivers (2 male and 5 females). Findings fell into the following themes: experiences with cancer diagnosis, experiences with treatment, roles of caregivers, information needs, views on cancer resources, and attitudes towards cancer research. The study identified several barriers across the cascade of care for breast cancer patients in the Botswana health system. These correspond to challenges with timely diagnosis and comprehensive management and highlight community level barriers to achieving the targets of the WHO Global Breast Cancer initiative (GBCI).

CONCLUSION

The study findings suggest PN programs have the potential to bridge barriers identified in the Botswana healthcare system by improving communication, meeting information needs, providing emotional or practical support, and by addressing logistical barriers to cancer diagnosis and treatment in Botswana.

Patient Navigation for Timely, Guideline-Adherent Adjuvant Therapy for Head and Neck Cancer: A National Landscape Analysis

BACKGROUND

Aligned with the NCCN Clinical Practice Guidelines in Oncology for Head and Neck Cancers, in November 2021 the Commission on Cancer approved initiation of postoperative radiation therapy (PORT) within 6 weeks of surgery for head and neck cancer (HNC) as its first and only HNC quality metric. Unfortunately, >50% of patients do not commence PORT within 6 weeks, and delays disproportionately burden racial and ethnic minority groups. Although patient navigation (PN) is a potential strategy to improve the delivery of timely, equitable, guideline-adherent PORT, the national landscape of PN for this aspect of care is unknown.

MATERIALS AND METHODS

From September through November 2022, we conducted a survey of health care organizations that participate in the American Cancer Society National Navigation Roundtable to understand the scope of PN for delivering timely, guideline-adherent PORT for patients with HNC.

RESULTS

Of the 94 institutions that completed the survey, 89.4% (n=84) reported that at least part of their practice was dedicated to navigating patients with HNC. Sixty-eight percent of the institutions who reported navigating patients with HNC along the continuum (56/83) reported helping them begin PORT. One-third of HNC navigators (32.5%; 27/83) reported tracking the metric for time-to-PORT at their facility. When estimating the timeframe in which the NCCN and Commission on Cancer guidelines recommend commencing PORT, 44.0% (37/84) of HNC navigators correctly stated ≤6 weeks; 71.4% (60/84) reported that they did not know the frequency of delays starting PORT among patients with HNC nationally, and 63.1% (53/84) did not know the frequency of delays at their institution.

CONCLUSIONS

In this national landscape survey, we identified that PN is already widely used in clinical practice to help patients with HNC start timely, guideline-adherent PORT. To enhance and scale PN within this area and improve the quality and equity of HNC care delivery, organizations could focus on providing better education and support for their navigators as well as specialization in HNC.

How do navigation programs address the needs of those living in the community with advanced, life-limiting Illness? A realist evaluation of programs in Canada

BACKGROUND

We sought to identify innovative navigation programs across Canadian jurisdictions that target their services to individuals affected by life-limiting illness and their families, and articulate the principal components of these programs that enable them to address the needs of their clients who are living in the community.

METHODS

This realist evaluation used a two-phased approach. First, we conducted a horizon scan of innovative community-based navigation programs across Canadian jurisdictions to identify innovative community-based navigation programs that aim to address the needs of community-dwelling individuals affected by life-limiting illness. Second, we conducted semi-structured interviews with key informants from each of the selected programs. Informants included individuals responsible for managing and delivering the program and decision-makers with responsibility and/or oversight of the program. Analyses proceeded in an iterative manner, consistent with realist evaluation methods. This included iteratively developing and refining Context-Mechanism-Outcome (CMO) configurations, and developing the final program theory.

RESULTS

Twenty-seven navigation programs were identified from the horizon scan. Using specific eligibility criteria, 11 programs were selected for subsequent interviews and in-depth examination. Twenty-three participants were interviewed from these programs, which operated in five Canadian provinces. The programs represented a mixture of community (non-profit or volunteer), research-initiated, and health system programs. The final program theory was articulated as: navigation programs can improve client outcomes if they have supported and empowered staff who have the time and flexibility to personalize care to the needs of their clients.

CONCLUSIONS

The findings highlight key principles (contexts and mechanisms) that enable navigation programs to develop client relationships, personalize care to client needs, and improve client outcomes. These principles include staff (or volunteer) knowledge and experience to coordinate health and social services, having a point of contact after hours, and providing staff (and volunteers) time and flexibility to develop relationships and respond to individualized client needs. These findings may be used by healthcare organizations - outside of navigation programs - to work towards more person-centred care.

Lessons to inform interventions to reduce racial and ethnic health disparities within hematologic malignancies

Although racial and ethnic disparities in diagnosis, treatment, and survival have been well documented within the field of hematologic malignancies, very little work has focused on testing interventions that may reduce these disparities. The aim of this commentary is to review prior work in hematologic malignancies and explore new opportunities to develop disparity-reducing interventions by drawing from evidence-based strategies that have been successfully implemented in fields related to hematologic malignancies, including oncology and solid organ transplants. Relevant literature demonstrates that patient navigation and broader insurance coverage have been shown to reduce racial and ethnic disparities among patients with solid malignancies such as colorectal and breast cancer. Evidence-based strategies that might be most applicable to the field of hematologic malignancies include patient navigation and policy changes.

Improving Uptake of Cancer Genetic Risk Assessment in a Remote Tailored Risk Communication and Navigation Intervention: Large Effect Size but Room to Grow

PURPOSE

Cancer genetic risk assessment (CGRA) is recommended for women with ovarian cancer or high-risk breast cancer, yet fewer than 30% receive recommended genetic services, with the lowest rates among underserved populations. We hypothesized that compared with usual care (UC) and mailed targeted print (TP) education, CGRA uptake would be highest among women receiving a phone-based tailored risk counseling and navigation intervention (TCN).

METHODS

In this three-arm randomized trial, women with ovarian or high-risk breast cancer were recruited from statewide cancer registries in Colorado, New Jersey, and New Mexico. Participants assigned to TP received a mailed educational brochure. Participants assigned to TCN received the mailed educational brochure, an initial phone-based psychoeducational session with a health coach, a follow-up letter, and a follow-up navigation phone call.

RESULTS

Participants' average age was 61 years, 25.4% identified as Hispanic, 5.9% identified as non-Hispanic Black, and 17.5% lived in rural areas. At 6 months, more women in TCN received CGRA (18.7%) than those in TP (3%; odds ratio, 7.4; 95% CI, 3.0 to 18.3; P < .0001) or UC (2.5%; odds ratio, 8.9; 95% CI, 3.4 to 23.5; P < .0001). There were no significant differences in CGRA uptake between TP and UC. Commonly cited barriers to genetic counseling were lack of provider referral (33.7%) and cost (26.5%), whereas anticipated difficulty coping with test results (14.0%) and cost (41.2%) were barriers for genetic testing.

CONCLUSION

TCN increased CGRA uptake in a group of geographically and ethnically diverse high-risk breast and ovarian cancer survivors. Remote personalized interventions that incorporate evidence-based health communication and behavior change strategies may increase CGRA among women recruited from statewide cancer registries.

The Colocation Model in Community Cancer Care: A Description of Patient Clinical and Demographic Attributes and Referral Pathways

PURPOSE

Cancer disparities are well documented among Black, Indigenous, and People of Color, yet little is known about the characteristics of programs that serve these populations. Integrating specialized cancer care services within community settings is important for addressing the needs of historically marginalized populations. Our National Cancer Institute-Designated Cancer Center initiated a clinical outreach program incorporating cancer diagnostic services and patient navigation within a Federally Qualified Health Center (FQHC) to expedite evaluation and resolution of potential cancer diagnoses with the goal of collaboration between oncology specialists and primary care providers in a historically marginalized community in Boston, MA.

MATERIALS AND METHODS

Sociodemographic and clinical characteristics were analyzed from patients who were referred to the program for cancer-related care between January 2012 and July 2018.

RESULTS

The majority of patients self-identified as Black (non-Hispanic) followed by Hispanic (Black and White). Twenty-two percent of patients had a cancer diagnosis. Treatment and surveillance plans were established for those with and without cancer at a median time to diagnostic resolution of 12 and 28 days, respectively. The majority of patients presented with comorbid health conditions. There was a high prevalence of self-reported financial distress among patients seeking care through this program.

CONCLUSION

These findings highlight the wide spectrum of cancer care concerns in historically marginalized communities. This review of the program suggests that integrating cancer evaluation services within community-based primary health care settings offers promise for enhancing the coordination and delivery of cancer diagnostic services among historically marginalized populations and could be a method to address clinical access disparities.

The impact of substance use on health care utilization, treatment, and outcomes in patients with non-small cell lung cancer

BACKGROUND

Mortality from non-small cell lung cancer (NSCLC) has improved with screening and novel treatments. The substance use epidemic has threatened health outcomes in a variety of diseases, but little is known about how it is associated with NSCLC outcomes.

METHODS

We performed a retrospective cohort study of 211 patients with NSCLC treated at a safety-net hospital. Sociodemographic data and clinical outcomes were extracted via review of electronic medical records. Patients were stratified based on substance use status. Comparative and multivariable analyses were performed to evaluate baseline characteristics and lung cancer outcomes including survival.

RESULTS

Among 193 patients (91.5%) with information available on substance use, 24.9% reported substance use; specifically, alcohol, marijuana, and illicit substances. Patients with substance use were more likely to have increased health care utilization and poor social determinants of health, including safe housing, stable employment, and social support. There were no significant differences in treatment adherence. Only 6.3% of patients with substance use did not receive guideline concordant care (GCC) compared to 24.8% of patients without substance use; due to poor performance status, increased comorbidities, or loss to follow up. On univariable analysis, patients with substance use experienced inferior median overall survival (OS) if they had metastatic disease (0.40 vs. 1.03 years, P=0.01). However, in the multivariable analysis, substance use did not predict for survival. Independent predictors of mortality were sex (male HR, 1.67; 95% CI: 1.04-2.68; P=0.04), smoking status (current smoking HR, 2.63; 95% CI: 1.14-6.08; P=0.02), and stage (stage IV HR, 14.96; 95% CI: 6.28-35.63; P=0.008).

CONCLUSIONS

Substance use is associated with poor social determinants of health and increased health care utilization. On multivariable analysis, substance use was not independently associated with OS once guideline-concordant care was used. Future studies should focus on improving our understanding of these associations, delineating potential mechanisms, and developing evidence-based strategies to reduce health care utilization and overcome challenges related to poor social determinants of health.

Barriers and opportunities to measuring oncology patient navigation impact: Results from the National Navigation Roundtable survey

BACKGROUND

Patient navigation improves cancer care delivery for those most at risk for poor outcomes. Lack of sustainable funding threatens the full integration of navigation services into health care delivery systems. Standardized navigation metrics that document impact and identify best practices are necessary to support sustainability.

METHODS

The National Navigation Roundtable administered a web-based, cross-sectional survey to oncology patient navigation programs to identify barriers and facilitators to the use of navigation metrics. The 38-item survey asked about data-collection practices and specific navigation metrics used by the program. Exploratory and descriptive statistics were used to identify factors associated with data collection and reporting.

RESULTS

Seven hundred fifty respondents from across the country represented navigation programs across the continuum of care. Although 538 respondents (72%) reported participating in routine data collection, only one-half of them used data for reporting purposes. For the 374 programs that used electronic health records, only 40% had discrete, reportable navigation fields, and 25% had an identifier for navigated patients. Program funding was identified as the only characteristic associated with data collection, whereas the type of data collected was associated with work setting, participation in alternative payment models, and where on the continuum navigation services are provided. Respondents participating in an oncology accreditation program were more likely to collect specific outcome metrics across the continuum and to use those data for reporting purposes. The most common barriers to data collection were time (55%) and lack of support for complex data systems and/or platforms (50%).

CONCLUSIONS

Inconsistent data collection and reporting of oncology navigation programs remain a threat to sustainability. Aligning data collection with oncology accreditation, funding, and reimbursement is a viable path forward.

Assessment of patient navigation programs for breast cancer patients across the city of Boston

PURPOSE

Healthcare systems contribute to disparities in breast cancer outcomes. Patient navigation is a widely cited system-based approach to improve outcomes among populations at risk for delays in care. Patient navigation programs exist in all major Boston hospitals, yet disparities in outcomes persist. The objective of this study was to conduct a baseline assessment of navigation processes at six Boston hospitals that provide breast cancer care in preparation for an implementation trial of standardized navigation across the city.

METHODS

We conducted a mixed methods study in six hospitals that provide treatment to breast cancer patients in Boston. We administered a web-based survey to clinical champions (n = 7) across six sites to collect information about the structure of navigation programs. We then conducted in-person workflow assessments at each site using a semi-structured interview guide to understand site-specific implementation processes for patient navigation programs. The target population included administrators, supervisors, and patient navigators who provided breast cancer treatment-focused care.

RESULTS

All sites offered patient navigation services to their patients undergoing treatment for breast cancer. We identified wide heterogeneity in terms of how programs were funded/resourced, which patients were targeted for navigation, the type of services provided, and the continuity of those services relative to the patient's cancer treatment.

CONCLUSIONS

The operationalization of patient navigation varies widely across hospitals especially in relation to three core principles in patient navigation: providing patient support across the care continuum, targeting services to those patients most likely to experience delays in care, and systematically screening for and addressing patients' health-related social needs. Gaps in navigation across the care continuum present opportunities for intervention.

Catalyzing Navigation for Breast Cancer Survivorship (CaNBCS) in Safety-Net Settings: A Mixed Methods Study

Purpose

The current number of breast cancer survivors (BCS) in the United States is approximately 3.8 million, and this number is further expected to increase with improvement in treatments. Survivorship care plans (SCPs) are patient-centered tools that are designed to meet cancer survivors' informational needs about their treatment history, recommended health care, and health maintenance. However, the data on SCP benefits remain uncertain, especially in low-income and racial and ethnic minority cancer survivors. Patient navigation is an effective intervention to improve patient adherence and experience of interdisciplinary breast cancer treatment.

Objectives

This study sought to understand the role of lay patient navigators (LPN) in survivorship care planning for BCS in safety-net settings.

Methods

This study is a mixed methods pilot randomized clinical trial to understand the role of patient navigation in cancer survivorship care planning in a public hospital. We invited BCS who had completed active breast cancer treatment within 5 years. LPNs discussed survivorship care planning and survivorship care-related issues with BCS in the intervention arm over a 6-month intervention period and accompanied patients to their primary care appointment. LPNs also encouraged survivors to discuss health care issues with oncology and primary care providers. The primary objective was to assess BCS’ health-related quality of life (HRQOL). The secondary objectives were self-efficacy and implementation. We assessed implementation with 45–60-min semi-structured interviews with 15 BCS recruited from the intervention arm and 60-min focus groups with the oncologists and separately with LPNs.

Results

We enrolled 40 patients, 20 randomized to usual care and 20 randomized to LPN navigation. We did not find a statistically significant difference between the two arms in HRQOL. There was also no difference in self-efficacy between the two arms. Qualitative analysis identified implementation barriers to intervention that may have contributed to less effective intervention.

Implications for Cancer Survivors

Future survivorship care planning interventions need to consider: Cancer survivors’ needs and preferences, the need for dedicated resources, and the role of electronic health records in survivorship care plan delivery.

A qualitative study of mechanisms influencing social inequality in cancer communication

OBJECTIVE

To understand and describe mechanisms influencing social inequality in cancer communication between patients, companions and healthcare professionals.

METHODS

The study was based on observations of 104 encounters and 30 semi-structured interviews with nurses and medical doctors on three Danish oncology wards. Observations, interviews and subsequent analysis were guided by the theoretical framework of cultural health capital developed by Shim to investigate mechanisms that may generate social inequality in cancer communication. The analysis addressed both interactive processes and interpretative meanings.

RESULTS

Information exchange was affected by (1) patient insight and preparation, (2) the presence of companions, and (3) communicating on patients' "home ground." Patients who, on the basis of language and hygiene, were assessed to have low capacity, received less information. Lack of mutual exchange of information left healthcare professionals and patients with fewer opportunities to provide-or receive-the best treatment.

CONCLUSION

Exchange of information between patients, companions and healthcare professionals is co-constructed in a mutual dynamic. To avoid social inequality in cancer communication, it is crucial that questions and answers allow proportionate insight into disease and treatment both for patients and for healthcare professionals.

Is nurse-led case management effective in improving treatment outcomes for cancer patients? A systematic review and meta-analysis

AIMS

To identify and synthesize the outcomes of nurse-led case management interventions for improving cancer treatment.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

PubMed, MEDLINE, CINAHL, EMBASE, Cochrane Library and CEPS were searched for articles published from inception till June 2019, and search was finalized in January 2020.

REVIEW METHODS

The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement guidelines. The quality of evidence was assessed using Joanna Briggs Institute Critical Appraisal Tools. Outcomes were analysed by using a pool of data of 95% confidence intervals (CIs), p value and fitting model based on heterogeneity of test results.

RESULTS

Eleven articles were included in the meta-analysis. When compared with the regular care group, the nurse-led case management group had: 1) shorter time from diagnosis to treatment by 9.07 days, 2) an improved treatment completion rates (OR = 2.45) and 3) more number of patients received hormone therapy.

CONCLUSION

The synthesized results presented that nurse-led case management is more effective than regular care in improving treatment timeliness, treatment completion rates and hormone therapy rates.

Navigating a Path to Equity in Cancer Care: The Role of Patient Navigation

Notable barriers exist in the delivery of equitable care for all patients with cancers. Social determinants of health at distal, intermediate, and proximal levels impact cancer care. Patient navigation is a patient-centered intervention that functions across these overlapping determinants to increase access to cancer services throughout the cancer care continuum. There is a need to standardize patient navigation training while remaining responsive to local contexts of care and a need to implement patient navigation programs with a health equity lens to address cancer care inequities.

Primary and Secondary Prevention of Lung Cancer: Tobacco Treatment

Tobacco dependence is the most consequential target to reduce the burden of lung cancer worldwide. Quitting after a cancer diagnosis can improve cancer prognosis, overall health, and quality of life. Several oncology professional organizations have issued guidelines stressing the importance of tobacco treatment for patients with cancer. Providing tobacco treatment in the context of lung cancer screening is another opportunity to further reduce death from lung cancer. In this review, the authors describe the current state of tobacco dependence treatment focusing on new paradigms and approaches and their particular relevance for persons at risk or on treatment for lung cancer.

The Role of Care Navigators Working with People with Dementia and Their Caregivers

BACKGROUND

Care navigation is an approach to personalized care management and care coordination that can help overcome barriers to care. Care navigation has not been extensively studied in dementia, where health care workforce innovations are needed as a result of increasing disease prevalence and resulting costs to the health care system.

OBJECTIVE

To identify facilitators and barriers to care navigation in dementia and to assess dementia caregiver satisfaction with care navigation.

METHODS

Methods include qualitative research (interviews, focus groups, observations) with "Care Team Navigators" (CTNs) who were part of a dementia care navigation program, the Care Ecosystem, and a quantitative survey with caregivers about their experiences with CTNs. Transcripts were analyzed to identify themes within the data.

RESULTS

CTNs identified the following facilitators to care navigation in dementia: working closely with caregivers; providing emotional support; tailoring education and resources; and coordinating with a clinical team around issues ranging from clinical questions to financial and legal decision-making. The barriers CTNS identified included burn-out, the progressive nature of the disease; coordinating with primary care providers; and identifying resources for dyads who are low-income, do not speak English, or live in rural areas. Caregivers across both sites highly rated CTNs, though satisfaction was higher among those in Nebraska and Iowa.

CONCLUSIONS

Innovative approaches to care delivery in dementia are crucial. Care navigation offers a feasible model to train unlicensed people to deliver care as a way to deliver larger-scale support for the growing population of adults living with dementia and their caregivers.

Systematic Patient Navigation Strategies to Scale Breast Cancer Disparity Reduction by Improved Cancer Prevention and Care Delivery Processes

PURPOSE

Patient navigation uses trained personnel to eliminate barriers to timely care across all phases of the health care continuum, thereby reducing health disparities. However, patient navigation has yet to be systematized in implementation models to improve processes of care at scale rather than remain a band-aid approach focused solely on improving care for the individual patient. The 4R systems engineering approach (right information and right treatment to the right patient at the right time) uses project management discipline principles to develop care sequence templates that serve as patient-centered project plans guiding patients and their care team.

METHODS

A case-study approach focused on the underserved patient shows how facilitators to timely breast cancer screening and care pragmatically identified as emergent data by patient navigators can be actionized by iteratively revising 4R care sequence templates to incorporate new insights as they emerge.

RESULTS

Using a case study of breast cancer screening of a low-income patient, we illustrate how 4R care sequence templates can be revised to incorporate emergent facilitators to care identified through patient navigation.

CONCLUSION

Use of care sequence templates can inform the care team to optimize a particular patient's care, while functioning as a learning health care system for process improvement of patient care and patient navigation scaling. A learning health care system approach that systematically integrates data patterns emerging from multiple patient navigation experiences through in-person navigators and 4R care sequence templates may improve processes of care and allow patient navigation scaling to reduce cancer disparities.

Translating research into practice: Protocol for a community-engaged, stepped wedge randomized trial to reduce disparities in breast cancer treatment through a regional patient navigation collaborative

BACKGROUND

Racial and socioeconomic disparities in breast cancer mortality persist. In Boston, MA, Black, Non-Hispanic women and Medicaid-insured individuals are 2-3 times more likely to have delays in treatment compared to White or privately insured women. While evidence-based care coordination strategies for reducing delays exist, they are not systematically implemented across healthcare settings.

METHODS

Translating Research Into Practice (TRIP) utilizes community engaged research methods to address breast cancer care delivery disparities. Four Massachusetts Clinical and Translational Science Institute (CTSI) hubs collaborated with the Boston Breast Cancer Equity Coalition (The Coalition) to implement an evidence-based care coordination intervention for Boston residents at risk for delays in breast cancer care. The Coalition used a community-driven process to define the problem of care delivery disparities, identify the target population, and develop a rigorous pragmatic approach. We chose a cluster-randomized, stepped-wedge hybrid type I effectiveness-implementation study design. The intervention implements three evidence-based strategies: patient navigation services, a shared patient registry for use across academic medical centers, and a web-based social determinants of health platform to identify and address barriers to care. Primary clinical outcomes include time to first treatment and receipt of guideline-concordant treatment, which are captured through electronic health records abstraction. We will use mixed methods to collect the secondary implementation outcomes of acceptability, adoption/penetration, fidelity, sustainability and cost.

CONCLUSION

TRIP utilizes an innovative community-driven research strategy, focused on interdisciplinary collaborations, to design and implement a translational science study that aims to more efficiently integrate proven health services interventions into clinical practice.

Increasing health service access by expanding disease coverage and adding patient navigation: challenges for patient satisfaction

BACKGROUND

Cancer control programs have added patient navigation to improve effectiveness in underserved populations, but research has yielded mixed results about their impact on patient satisfaction. This study focuses on three related research questions in a U.S. state cancer screening program before and after a redesign that added patient navigators and services for chronic illness: Did patient diversity increase; Did satisfaction levels improve; Did socioeconomic characteristics or perceived barriers explain improved satisfaction.

METHODS

Representative statewide patient samples were surveyed by phone both before and after the program design. Measures included satisfaction with overall health care and specific services, as well as experience of eleven barriers to accessing health care and self-reported health and sociodemographic characteristics. Multiple regression analysis is used to identify independent effects.

RESULTS

After the program redesign, the percentage of Hispanic and African American patients increased by more than 200% and satisfaction with overall health care quality rose significantly, but satisfaction with the program and with primary program staff declined. Sociodemographic characteristics explained the apparent program effects on overall satisfaction, but perceived barriers did not. Further analysis indicates that patients being seen for cancer risk were more satisfied if they had a patient navigator.

CONCLUSIONS

Health care access can be improved and patient diversity increased in public health programs by adding patient navigators and delivering more holistic care. Effects on patient satisfaction vary with patient health needs, with those being seen for chronic illness likely to be less satisfied with their health care than those being seen for cancer risk. It is important to use appropriate comparison groups when evaluating the effect of program changes on patient satisfaction and to consider establishing appropriate satisfaction benchmarks for patients being seen for chronic illness.

Evolution of a longitudinal, multidisciplinary, and scalable patient navigation matrix model

This Longitudinal patient navigation Matrix Model was developed to overcome barriers across the cancer care continuum by offering prepatients, patients, and their families with support services. The extraordinary heterogeneity of patient needs during cancer screening, risk assessment, treatment, and survivorship as well as the vast heterogeneity of oncology care settings make it nearly impossible to follow a static navigation model. Our model of patient cancer navigation is unique as it enhances the traditional model by being highly adaptable based on both patient and family needs and scalable based on institutional needs and resources (eg, clinical volumes, financial resources, and community‐based resources). This relatively new operational model for system‐wide and systematic navigation incorporates a carefully cultivated supportive care program that evolved over the last decade from a bottom up approach that identified patient and family needs and developed appropriate resources. A core component of this model includes shifting away from department‐centric operations. This model does not require a patient to opt in or independently be able to report their needs or ask for services—it is an opt out model. The multidisciplinary “cross‐training” model can also facilitate reimbursement and sustainability by clarifying the differentiating actions that define navigation services: identification of barriers to quality care and specific actions taken to overcome those barriers, across the full continue of cancer care from community engagement to survivorship or end‐of‐life care.

Standardized activities for lay patient navigators in breast cancer care: Recommendations from a citywide implementation study

BACKGROUND

There is a need for guidelines on patient navigation activities to promote both the quality of patient navigation and the standards of reimbursement for these services because a lack of reimbursement is a major barrier to the implementation, maintenance, and sustainability of these programs.

METHODS

A broad community-based participatory research process was used to identify the needs of patients for navigation. A panel of stakeholders of clinical providers was convened to identify specific activities for navigators to address the needs of patients and providers with the explicit goal of reducing delays in the initiation of cancer treatment and improving adherence to the care plan.

RESULTS

Specific activities were identified that could be generalized to all patient navigation programs for care during active cancer management to address the needs of vulnerable communities.

CONCLUSIONS

Oncology programs that seek to implement lay patient navigation may benefit from the adoption of these activities for quality monitoring. Such activities are necessary as we consider reimbursement strategies for navigators without clinical training or licensure.

Establishing effective patient navigation programs in oncology

PURPOSE

Recent advances in cancer treatment have resulted in greatly improved survival, and yet many patients in the USA have not benefited due to poor access to healthcare and difficulty accessing timely care across the cancer care continuum. Recognizing these issues and the need to facilitate discussions on how to improve navigation services for patients with cancer, the National Cancer Policy Forum of the National Academies of Sciences, Engineering, and Medicine (NASEM) held a workshop entitled, "Establishing Effective Patient Navigation Programs in Oncology. The purpose of this manuscript is to disseminate the conclusions of this workshop while providing a clinically relevant review of patient navigation in oncology.

DESIGN

Narrative literature review and summary of workshop discussions RESULTS: Patient navigation has been shown to be effective at improving outcomes throughout the spectrum of cancer care. Work remains to develop consensus on scope of practice and evaluation criteria and to align payment incentives and policy.

CONCLUSION

Patient navigation plays an essential role in overcoming patient- and system-level barriers to improve access to cancer care and outcomes for those most in need.

The efficacy and cost-effectiveness of patient navigation programs across the cancer continuum: A systematic review

Published studies regarding patient navigation (PN) and cancer were reviewed to assess quality, determine gaps, and identify avenues for future research. The PubMed and EMBASE databases were searched for studies investigating the efficacy and cost-effectiveness of PN across the cancer continuum. Each included article was scored independently by 2 separate reviewers with the Quality Assessment Tool for Quantitative Studies. The current review identified 113 published articles that assessed PN and cancer care, between August 1, 2010, and February 1, 2018, 14 of which reported on the cost-effectiveness of PN programs. Most publications focused on the effectiveness of PN in screening (50%) and diagnosis (27%) along the continuum of cancer care. Many described the effectiveness of PN for breast cancer (52%) or colorectal cancer outcomes (51%). Most studies reported favorable outcomes for PN programs, including increased uptake of and adherence to cancer screenings, timely diagnostic resolution and follow-up, higher completion rates for cancer therapy, and higher rates of attending medical appointments. Cost-effectiveness studies showed that PN programs yielded financial benefits. Quality assessment showed that 75 of the 113 included articles (65%) had 2 or more weak components. In conclusion, this review indicates numerous gaps within the PN and cancer literature where improvement is needed. For example, more research is needed at other points along the continuum of cancer care outside of screening and diagnosis. In addition, future research into the effectiveness of PN for understudied cancers outside of breast and colorectal cancer is necessary along with an assessment of cost-effectiveness and more rigorous reporting of study designs and results in published articles.

Demographic, clinical, and geographical factors associated with lack of receipt of physician recommended chemotherapy in women with breast cancer in Texas

PURPOSE

Identifying demographic, clinical, and geographical factors that contribute to disparities in the receipt of physician recommended chemotherapy in breast cancer patients.

METHODS

The Texas Cancer Registry was used to identify women aged ≥ 18 years with invasive breast cancer diagnosed from 2007 to 2011 who received a recommendation for chemotherapy. Multivariable logistic regression was performed to determine associations between demographic and clinical factors and the receipt of chemotherapy. Cox proportional regression was used to estimate the hazard ratio (HR) for overall survival. Spatial analysis was conducted using Poisson models for breast cancer mortality and receipt of chemotherapy.

RESULTS

Age ≥ 65 years, residence in areas with > 20% poverty index, and early disease stage were associated with lack of receipt of chemotherapy (all p < 0.001). Lack of receipt of chemotherapy was associated with decreased overall survival (HR 1.33, 95% CI 1.12-1.59, p = 0.001). A 38-county cluster in West Texas had lower receipt of chemotherapy (relative risk 0.88, p = 0.02) and increased breast cancer mortality (p = 0.03) compared to the rest of Texas.

CONCLUSION

Older age, increased poverty and rural geographical location are barriers to the receipt of chemotherapy. Interventions that target these barriers may reduce health disparities and improve breast cancer survival.

Effectiveness of interventions to improve cancer treatment and follow-up care in socially disadvantaged groups

OBJECTIVE

To identify and characterize the interventions that aimed to improve cancer treatment and follow-up care in socially disadvantaged groups. To summarize the state of the art for clinicians and researchers.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were randomized controlled trials and quasi-experimental studies with a control group (usual care or enhanced usual care) conducted in Organization for Economic Co-operation and Development (OECD) member countries and published until 2016.

RESULTS

Thirty-one interventions were identified, the majority of which were conducted in the United States in patients with breast cancer. Most interventions aimed to decrease social inequalities based on ethnicity/race and/or socioeconomic level, with fewer interventions targeting inequalities based on geographical area. The most frequently assessed outcomes were quality of life (n = 20) and psychosocial factors (n = 20), followed by treatment adherence or satisfaction (n = 12,), knowledge (n = 11), pain management (n = 10), and lifestyle habits (n = 3).

CONCLUSIONS

The impact of interventions designed to improve cancer treatment and follow-up care in socially disadvantages groups is multifactorial. Multicomponent-intervention approaches and cultural adaptations are common, and their effectiveness should be evaluated in the populations of interest. More interventions are needed from outside the Unite States and in patients with cancers other than breast cancer, targeting gender or geographical inequalities and addressing key outcomes such as treatment adherence or symptom management.

An Exploration of Patient Navigation and Community Health Worker Activities Across National Comprehensive Cancer Control Programs

Purpose: Health disparities persist across the cancer care continuum. Patient navigator (PN) and community health worker (CHW) interventions are designed to increase health equity. National Comprehensive Cancer Control Program (NCCCP) awardees develop and implement plans to coordinate cancer prevention and control activities, including supporting PN and CHW interventions. This content analysis examined NCCCP action plans to assess the extent to which jurisdictions report engaging in PN and/or CHW activities.

Methods: We abstracted PN and CHW content from NCCCP action plans and coded content according to specific areas of PN and/or CHW intervention (e.g., screening, survivorship, and cancer type), used descriptive statistics to characterize overall results, and calculated chi-squares to determine whether programs engaged PNs and CHWs differently.

Results: Eighty-two percent (n=53) of 65 NCCCP action plans had content related to PN and/or CHW activities, with more PN language (83%) than CHW (58%). These action plans described engaging PNs and CHWs in activities across the cancer continuum, but particularly for screening (60%) and survivorship (55%). Eighty-one percent of these plans described activities related to workforce development, such as training and standardizing roles and competencies. Programs engaged CHWs more often than PNs for outreach and in community settings.

Conclusion: The majority of NCCCP awardees reported engaging in PN and/or CHW activities. Understanding how NCCCP awardees engage PNs and CHWs, including awardees' needs for workforce development in this area, can help Centers for Disease Control and Prevention provide more focused technical assistance as programs increase engagement of PNs and CHWs to improve health equity.

Patient Navigation to Enhance Access to Care for Underserved Patients with a Suspicion or Diagnosis of Cancer

BACKGROUND

Interventions aimed at improving access to timely cancer care for patients in low- and middle-income countries (LMIC) are urgently needed. We aimed to evaluate a patient navigation (PN) program to reduce referral time to cancer centers for underserved patients with a suspicion or diagnosis of cancer at a public general hospital in Mexico City.

MATERIALS AND METHODS

From January 2016 to March 2017, consecutive patients aged >18 years with a suspicion or diagnosis of cancer seen at Ajusco Medio General Hospital in Mexico City who required referral to a specialized center for diagnosis or treatment were enrolled. A patient navigator assisted patients with scheduling, completing paperwork, obtaining results in a timely manner, transportation, and addressing other barriers to care. The primary outcome was the proportion of patients who obtained a specialized consultation at a cancer center within the first 3 months after enrollment.

RESULTS

Seventy patients (median age 54, range 19-85) participated in this study. Ninety-six percent (n = 67) identified >1 barrier to cancer care access. The most commonly reported barriers to health care access were financial burden (n = 50) and fear (n = 37). Median time to referral was 7 days (range 0-49), and time to specialist appointment was 27 days (range 1-97). Ninety-one percent of patients successfully obtained appointments at cancer centers in <3 months.

CONCLUSION

Implementing PN in LMIC is feasible, and may lead to shortened referral times for specialized cancer care by helping overcome barriers to health care access among underserved patients.

IMPLICATIONS FOR PRACTICE

A patient navigation program for patients with suspicion or diagnosis of cancer in a second-level hospital was feasible and acceptable. It reduced patient-reported barriers, and referral time to specialized appointments and treatment initiation were within international recommended limits. Patient navigation may improve access to care for underserved patients in developing countries.

Gendered and racialized social expectations, barriers, and delayed breast cancer diagnosis

BACKGROUND

Black women are more likely to be diagnosed at a later stage of breast cancer in part due to barriers to timely screening mammography, resulting in poorer mortality and survival outcomes. Patient navigation that helps to overcome barriers to the early detection of breast cancer is an effective intervention for reducing breast cancer disparity. However, the ability to recognize and seek help to overcome barriers may be affected by gendered and racialized social expectations of women.

METHODS

Data from a randomized controlled trial, the Patient Navigation in Medically Underserved Areas study, were used. The likelihood of obtaining a follow-up screening mammogram was compared between women who identified ≥1 barriers and those who did not.

RESULTS

Of the 3754 women who received the Patient Navigation in Medically Underserved Areas navigation intervention, approximately 14% identified ≥ 1 barriers, which led to additional navigator contacts. Consequently, those women who reported barriers were more likely to obtain a subsequent screening mammogram. Black women, women living in poverty, and women with a higher level of distrust were less likely to report barriers.

CONCLUSIONS

Minority women living in poverty have always been the source of social support for others. However, gendered and racialized social expectations may affect the ways in which women seek help for their own health needs. A way to improve the effectiveness of navigation would be to recognize how minority women's gender images and expectations could shape how they seek help and support. A report of no barriers does not always translate into no problems. Proactive approaches to identify potential barriers may be beneficial.

Utilization of Patient Navigators in an Urban Academic Pediatric Primary Care Practice

Navigating health care systems can be a challenge for families. A retrospective descriptive cohort analysis was conducted assessing referrals to patient navigators (PNs) in one urban academic pediatric primary care practice. PNs tracked referral processes and a subset of PN referrals was assessed for markers of successful referrals. The most common reasons for referral were assistance overcoming barriers to care (46%), developmental concerns (38%), and adherence/care coordination concerns (14%). Significant predictors of referral were younger age, medical complexity, public insurance, male sex, and higher rates of no-show to visits in primary or subspecialist care. The majority of referrals were resolved. The referrals for process-oriented needs were significantly more successful than those for other concerns. PNs were more effective for discrete process tasks than for those that required behavior change by patients or families. Future directions include analysis of cost effectiveness of the PN program and analysis of parent and primary care provider experience.

A conceptual model of social networks and mechanisms of cancer mortality, and potential strategies to improve survival

Women with larger personal social networks have better breast cancer survival and a lower risk of mortality. However, little work has examined the mechanisms through which social networks influence breast cancer outcomes and cancer outcomes more generally, potentially limiting the development of feasible, clinically effective interventions. In fact, much of the emphasis in cancer research regarding the influence of social relationships on cancer outcomes has focused on the benefits of the provision of social support to patients, especially through peer support groups, and only more recently through patient navigation. Though critically important, there are other ways through which social relationships might influence outcomes, around which interventions might be developed. In addition to social support, these include social resources, social norms, social contagion, social roles, and social burdens and obligations. This narrative review addresses how social networks may influence cancer outcomes and discusses potential strategies for improving outcomes given these relationships. The paper (a) describes background and limitations of previous research, (b) outlines terms and provides a conceptual model that describes interrelationships between social networks and relevant variables and their hypothesized influence on cancer outcomes, (c) clarifies social and psychosocial mechanisms through which social networks affect downstream factors, (d) describes downstream behavioral, treatment, and physiological factors through which these subsequently influence recurrence and mortality, and (e) describes needed research and potential opportunities to enhance translation. Though most literature in this area pertains to breast cancer, this review has substantial relevance for cancer outcomes generally. Further clarification and research regarding potential mechanisms are needed to translate epidemiological findings on social networks into clinical and community strategies to improve cancer outcomes.

A contemporary framework of health equity applied to gynecologic cancer care: A Society of Gynecologic Oncology evidenced-based review

Health disparities are defined as the preventable difference in the burden of disease, injury, and violence, or opportunity to achieve optimal health that socially disadvantaged populations experience compared to the population as a whole. Disparities in incidence and cancer outcomes for women with gynecologic malignancies have been well described particularly for American women of Black race. The etiology of these disparities has been tied to socio-economics, cultural, educational and genetic factors. While access to high quality treatment has been primarily linked to survival from cervical and ovarian cancer, innate biologic distinctions have been principally cited as reasons for differences in incidence and mortality in cancers of the uterine corpus. This article will update the framework of disparities to incorporate a broader understanding of the social determinants of health and how they affect health equity by addressing the root causes of disparities within the health care system. Special populations are identified who are at risk for health inequities which include but are not limited to Black race, underserved racial and ethnic minorities (e.g. indigenous peoples, low English fluency), trans/gender nonconforming people and rural populations. Each of these populations at risk have unique structural barriers within the healthcare system impacting gynecologic cancer outcomes. The authors provide practical recommendations for practitioners aimed at eliminating cancer related outcome disparities.

Lay Patient Navigators’ Perspectives of Barriers, Facilitators and Training Needs in Initiating Advance Care Planning Conversations With Older Patients With Cancer

Context:

Respecting Choices is an evidence-based model of facilitating advance care planning (ACP) conversations between health-care professionals and patients. However, the effectiveness of whether lay patient navigators can successfully initiate Respecting Choices ACP conversations is unknown. As part of a large demonstration project (Patient Care Connect [PCC]), a cohort of lay patient navigators underwent Respecting Choices training and were tasked to initiate ACP conversations with Medicare beneficiaries diagnosed with cancer.

Objectives:

This article explores PCC lay navigators’ perceived barriers and facilitators in initiating Respecting Choices ACP conversations with older patients with cancer in order to inform implementation enhancements to lay navigator-facilitated ACP.

Methods:

Twenty-six lay navigators from 11 PCC cancer centers in 4 states (Alabama, George, Tennessee, and Florida) completed in-depth, one-on-one semistructured interviews between June 2015 and August 2015. Data were analyzed using a thematic analysis approach.

Results:

This evaluation identifies 3 levels—patient, lay navigator, and organizational factors in addition to training needs that influence ACP implementation. Key facilitators included physician buy-in, patient readiness, and navigators’ prior experience with end-of-life decision-making. Lay navigators’ perceived challenges to initiating ACP conversations included timing of the conversation and social and personal taboos about discussing dying.

Conclusion:

Our results suggest that further training and health system support are needed for lay navigators playing a vital role in improving the implementation of ACP among older patients with cancer. The lived expertise of lay navigators along with flexible longitudinal relationships with patients and caregivers may uniquely position this workforce to promote ACP.

Outcomes research examining treatments, quality of life and costs in HER2-negative and triple-negative metastatic breast cancer: a systematic literature review

Aim: With the aggregation of real-world data in healthcare, opportunities for outcomes research are growing. In this study, we summarize published literature examining comparative effectiveness research (CER), treatment patterns, quality of life (QoL) and costs in HER2-negative and triple-negative (TN) metastatic breast cancer (mBC). Methods: PubMed (2010–January 2016) and four conferences (2013–January 2016) were searched using MeSH/keywords, including mBC, QoL, morbidity and therapeutics. Studies relating to CER, treatment patterns, QoL, costs or treatment appropriateness in US patients with HER2-negative/TN mBC were included in the review. Results: Of 1782 identified records, 33 studies met full inclusion criteria: seven related to CER, 18 to treatment patterns, one to treatment appropriateness/navigation, two to QoL and five to costs. Studies varied in objectives, designs and outcomes. Study designs included retrospective chart reviews (52%), retrospective secondary database analyses (27%), economic models (12%), physician surveys (6%) and patient surveys (3%). 25 studies reported results on HER2-negative mBC, six on TN mBC and two on both subtypes. The most common end points examined were treatment patterns, overall survival and progression-free survival. Conclusion: Outcomes research in HER2-negative mBC in the USA was limited, specifically among TN patients, indicating an opportunity for further research in this high unmet need population. Endpoints and treatment options varied, thus, it is difficult to draw summary conclusions about these studies. Outcomes research examining real-world data in mBC has increased in recent years, and may continue to grow with the implementation of new policy programs.

Racial Disparities in Breast Cancer Survival: The Mediating Effects of Macro-Social Context and Social Network Factors

This study attempts to clarify the associations between macro-social and social network factors and the continuing racial disparities in breast cancer survival. The study improves on prior methodologies by using a neighborhood disadvantage measure that assesses both economic and social disadvantage and an ego-network measurement tool that assesses key social network characteristics. Our population-based sample included 786 breast cancer patients (nHWhite=388; nHBlack=398) diagnosed during 2005-2008 in Chicago, IL. The data included census-derived macro-social context, self-reported social network, self-reported demographic and medically abstracted health measures. Mortality data from the National Death Index (NDI) were used to determine 5-year survival. Based on our findings, neighborhood concentrated disadvantage was negatively associated with survival among nHBlack and nHWhite breast cancer patients. In unadjusted models, social network size, network density, practical support, and financial support were positively associated with 5-year survival. However, in adjusted models only practical support was associated with 5-year survival. Our findings suggested that the association between network size and breast cancer survival is sensitive to scaling of the network measure, which helps to explain inconsistencies in past findings. Social networks of nHWhites and nHBlacks differed in size, social support dimensions, network density, and geographic proximity. Among social factors, residence in disadvantaged neighborhoods and unmet practical support explained some of the racial disparity in survival. Differences in late stage diagnosis and comorbidities between nHWhites and nHBlacks also explained some of the racial disparity in survival. Our findings highlight the relevance of social factors, both macro and inter-personal in the racial disparity in breast cancer survival. Findings suggest that reduced survival of nHBlack women is in part due to low social network resources and residence in socially and economically deprived neighborhoods. To improve survival among breast cancer patients social policies need to continue improving health care access as well as racially patterned social and economic disadvantage.

Understanding Breast Cancer Knowledge and Barriers to Treatment Adherence: A Qualitative Study Among Breast Cancer Survivors

Disparities in breast cancer treatment receipt are common and multifactorial. Data are limited on how knowledge about one's breast cancer and understanding treatment rationales may impact treatment completion. In this qualitative analysis, we explored barriers to care with a focus on knowledge. We conducted 18 in-depth interviews with women from diverse socioeconomic backgrounds who were treated at Dana-Farber Cancer Institute (n = 12; Boston, MA) and Columbia University Medical Center (n = 6; New York, NY) and had undergone neo/adjuvant breast cancer treatment within the prior 3 years. Interviews focused on treatments received, adherence, barriers experienced, and questions related to breast cancer knowledge and treatment rationales. We analyzed transcribed interview recordings in N'Vivo using a two-stage coding process that allowed for both preconfigured and emergent themes. Answers for breast cancer knowledge were confirmed using medical records. In our analysis, over one-third of women reported incomplete therapy, including never initiating treatment, stopping treatment prematurely, or missing/delaying treatments due to logistical reasons (childcare, transportation) or patient preferences. Others reported treatment modifications because of provider recommendations. Nearly all women were able to accurately describe the rationale for recommended treatments. Among 17 women for whom medical records were available, women correctly reported 18–71% of their tumor characteristics; incorrect reporting was not consistently associated with treatment incompletion. In conclusion, logistical issues and patient preferences were the main reasons for incomplete therapy in our study. Understanding of treatment rationale was high, but breast cancer knowledge was variable. Further assessment of how knowledge may impact cancer care is warranted.

The Effects of Travel Burden on Outcomes After Resection of Extrahepatic Biliary Malignancies: Results from the US Extrahepatic Biliary Consortium

BACKGROUND

Surgical resection of extrahepatic biliary malignancies has been increasingly centralized at high-volume tertiary care centers. While this has improved outcomes overall, increased travel burden has been associated with worse survival for many other malignancies. We hypothesized that longer travel distances are associated with worse outcomes for these patients as well.

STUDY DESIGN

Data was analyzed from the US Extrahepatic Biliary Consortium database, which retrospectively reviewed patients who received resection of extrahepatic biliary malignancies at 10 high-volume centers. Driving distance to the patient's treatment center was measured for 1025 patients. These were divided into four quartiles for analysis: < 24.5, 24.5-57.2, 57.2-117, and < 117 mi. Cox proportional hazard models were then used to measure differences in overall survival.

RESULTS

No difference was found between the groups in severity of disease or post-operative complications. The median overall survival in each quartile was as follows: 1st = 1.91, 2nd = 1.60, 3rd = 1.30, and 4th = 1.39 years. Patients in the 3rd and 4th quartile had a significantly lower median household income (p = 0.0001) and a greater proportion Caucasian race (p = 0.0001). However, neither of these was independently associated with overall survival. The two furthest quartiles were found to have decreased overall survival (HR = 1.39, CI = 1.12-1.73 and HR = 1.3, CI = 1.04-1.62), with quartile 3 remaining significant after multivariate analysis (HR = 1.45, CI = 1.04-2.0, p = 0.028).

CONCLUSIONS

Longer travel distances were associated with decreased overall survival, especially in the 3rd quartile of our study. Patients traveling longer distances also had a lower household income, suggesting that these patients have significant barriers to care.

Patient Navigation Improves Subsequent Breast Cancer Screening After a Noncancerous Result: Evidence from the Patient Navigation in Medically Underserved Areas Study

BACKGROUND

Past efforts to assess patient navigation on cancer screening utilization have focused on one-time uptake, which may not be sufficient in the long term. This is partially due to limited resources for in-person, longitudinal patient navigation. We examine the effectiveness of a low-intensity phone- and mail-based navigation on multiple screening episodes with a focus on screening uptake after receiving noncancerous results during a previous screening episode.

METHODS

The is a secondary analysis of patients who participated in a randomized controlled patient navigation trial in Chicago. Participants include women referred for a screening mammogram, aged 50-74 years, and with a history of benign/normal screening results. Navigation services focused on identification of barriers and intervention via shared decision-making processes. A multivariable logistic regression intent-to-treat model was used to examine differences in odds of obtaining a screening mammogram within 2 years of the initial mammogram (yes/no) between navigated and non-navigated women. Sensitivity analyses were conducted to explore patterns across subsets of participants (e.g., navigated women successfully contacted before the initial appointment; women receiving care at Hospital C).

RESULTS

The final sample included 2,536 women (741 navigated, 1,795 non-navigated). Navigated women exhibited greater odds of obtaining subsequent screenings relative to women in the standard care group in adjusted models and analyses including women who received navigation before the initial appointment.

CONCLUSIONS

Our findings suggest that low-intensity navigation services can improve follow-up screening among women who receive a noncancerous result. Further investigation is needed to confirm navigation's impacts on longitudinal screening.

How will the 'cancer moonshot' impact health disparities?

In 1971, President Nixon signed into law the National Cancer Act (NCA), colloquially known as the "War on Cancer", which pushed cancer onto the national agenda and is credited for many subsequent increases in the knowledge of the molecular, cellular, and genetic causes and effects of cancer. But even though cancer mortality has declined overall in intervening years after the NCA, cancer health disparities persist in the form of higher cancer incidence and mortality rates among certain cancer types and certain populations. Breast and cervical cancers disproportionately affect African American, Hispanic, and American Indian Women. Colorectal cancer is the second leading cause of death for Latinos (with men and women combined). Forty-five years after the NCA, how will the next enormous cancer initiatives-President Barack Obama's Cancer Moonshot and the All of Us Research Program (formerly the Precision Medicine Initiative Cohort Program)-impact cancer health disparities? The emergence of precision medicine and the sharing of information across sectors are at the heart of these large national initiatives and hold vast potential to address complex health disparities that remain in incidence reporting, incidence, treatment, prognoses, and mortality among certain cancer types and racial/ethnic minorities, including African Americans and Hispanics/Latinos, compared to Whites. But clinical research efforts and data collection have historically lacked diverse representation for various reasons, posing a large risk to these national initiatives in their ability to develop diverse cohorts that adequately represent racial/ethnic minorities. Efforts to reduce disparities and increase diversity in study cohorts have emerged, from patient navigation, to use of mobile technology to collect data, to national consortiums dedicated to including diverse groups, to university training on health disparities. These efforts point to the need for the Cancer Moonshot and precision medicine leaders to develop a multifaceted approach to address disparities in health and healthcare to promote a diverse healthcare workforce, patient-centered care, maintenance of a database of information regarding the state of health disparities, and the institution of measurable goals for improving care across all ethnic groups. If these elements are included, it is possible that the Cancer Moonshot and precision medicine will benefit the entire population of our country.

Cancer Care Collaborative Approach to Optimize Clinical Care

A collaboration between clinicians and industrial engineers resulted in significant improvements in cancer screening, the development of toolkits, and more efficient care for hepatocellular carcinoma and breast, colorectal, lung, head and neck, and prostate cancers.

The effectiveness of patient navigation to improve healthcare utilization outcomes: A meta-analysis of randomized controlled trials

OBJECTIVE

To determine the effects of patient navigation (PN) on healthcare utilization outcomes using meta-analysis and the quality of evidence.

METHODS

Medical and social science databases were searched for randomized controlled trials published in English between 1989 and May 2015. The review process was guided by PRISMA. Included studies were assessed for quality using the Downs and Black tool. Data were extracted to assess the effect of navigation on: health screening rates, diagnostic resolution, cancer care follow-up treatment adherence, and attendance of care events. Random-effects models were used to compute risk ratios and I² statistics determined the impact of heterogeneity.

RESULTS

Of 3985 articles screened, 25 articles met inclusion criteria. Compared to usual care, patients who received PN were significantly more likely to access health screening (OR 2.48, 95% CI, 1.93-3.18, P<0.00001) and attend a recommended care event (OR 2.55, 95% CI, 1.27-5.10, P<0.01). PN was favoured to increase adherence to cancer care follow-up treatment and obtain diagnoses. Most studies involved trained lay navigators (n=12) compared to health professionals (n=9).

CONCLUSION

PN is effective to increase screening rates and complete care events.

PRACTICE IMPLICATIONS

PN is an effective intervention for use in healthcare.

Patient Navigation in Medically Underserved Areas study design: A trial with implications for efficacy, effect modification, and full continuum assessment

BACKGROUND

The Patient Navigation in Medically Underserved Areas study objectives are to assess if navigation improves: 1) care uptake and time to diagnosis; and 2) outcomes depending on patients' residential medically underserved area (MUA) status. Secondary objectives include the efficacy of navigation across 1) different points of the care continuum among patients diagnosed with breast cancer; and 2) multiple regular screening episodes among patients who did not obtain breast cancer diagnoses.

DESIGN/METHODS

Our randomized controlled trial was implemented in three community hospitals in South Chicago. Eligible participants were: 1) female, 2) 18+years old, 3) not pregnant, 4) referred from a primary care provider for a screening or diagnostic mammogram based on an abnormal clinical breast exam. Participants were randomized to 1) control care or 2) receive longitudinal navigation, through treatment if diagnosed with cancer or across multiple years if asymptomatic, by a lay health worker. Participants' residential areas were identified as: 1) established MUA (before 1998), 2) new MUA (after 1998), 3) eligible/but not designated as MUA, and 4) affluent/ineligible for MUA. Primary outcomes include days to initially recommended care after randomization and days to diagnosis for women with abnormal results. Secondary outcomes concern days to treatment initiation following a diagnosis and receipt of subsequent screening following normal/benign results.

DISCUSSION

This intervention aims to assess the efficacy of patient navigation on breast cancer care uptake across the continuum. If effective, the program may improve rates of early cancer detection and breast cancer morbidity.

Implementation of evidence-based patient navigation programs

BACKGROUND

Patient navigation refers to a direct patient care role that links patients with clinical providers and their support system and provides individualized support during cancer care, ensuring that patients have access to the knowledge and resources necessary to complete recommended treatment. While most reports have studied the role of patient navigators during the cancer screening or diagnostic process, emerging evidence indicates the benefits of patient navigation during active cancer treatment.

DISCUSSION

Reports in the literature are conflicting on the impact of patient navigation during cancer care and on the benefits to timely or quality care in all populations. Recent sub-analyses of the Patient Navigation Research Program data demonstrated specifically the benefits of targeting patient navigation to the most vulnerable populations, including those with low educational attainment, low income and unstable housing, less social support, multiple comorbidities, and minority race/ethnicity.

CONCLUSION

The implications of the Patient Navigation Research Program are that this resource is best utilized when directed to support the care of patients at locations with known challenges to timely care and for specific patients with risk factors for delays in care, including comorbidities, low educational attainment and low income. Implementation of patient navigation programs requires the following processes: needs assessment, selection of a navigator to meet the community and care needs, supervision and integration of the navigator into clinical processes, and systems support to facilitate the identification and tracking of those patients requiring patient navigation. There is a need for ongoing research on methods to fund and sustain patient navigation programs.

The State of the Science of Health Literacy Measurement

Advancing health literacy (HL) research requires high-quality HL measures. This chapter provides an overview of the state of the science of HL measurement: where the field started, currently is, and should be going. It is divided into eight key sections looking at (1) the history of HL measurement, (2) the relationship between HL definitions and measurement, (3) the HL conceptual domains most and least frequently measured, (4) the methods used to validate HL measures, (5) the characteristics of the participants in the measurement validation studies, (6) the practical considerations related to administering HL measures, (7) the advantages and disadvantages of using objective versus subjective HL measures, and (8) future directions for HL measurement. Based on the material presented in this chapter, the following conclusions can be drawn. First, there is an enormous proliferation of HL measures and this growth presents both opportunities and challenges for the field. Second, to move the field forward, there is an urgent need to better align HL measurement with definitions of HL. Third, some HL domains, such as numeracy, are measured more often than others, such as speaking and listening. Consequently, it is important to think about novel mechanisms to measure HL domains that are rarely measured. Fourth, HL measures are most often developed, validated, and refined using classical measurement approaches. However, strong empirical and practical rationales suggest making an assertive shift toward using modern measurement approaches. Fifth, most HL measures are not well validated for use in minority populations; consequently, future validation studies should be mindful of validation samples. Sixth, HL measures can be administered using multiple modes, most frequently via paper-and-pencil surveys. Identifying which mode of administration is most suitable requires reflecting on the underlying measurement purpose and the characteristics of the participants being measured. These considerations should also be made when deciding between a subjective versus objective HL measure. Cumulatively, this chapter provides tools to help readers select and use the most appropriate measures of HL for their needs. It also provides rationale and strategies for moving the science of HL measurement forward.

Patient Navigation in Breast Cancer Treatment and Survivorship: A Systematic Review

PURPOSE

Patient navigation is an intervention approach that improves cancer outcomes by reducing barriers and facilitating timely access to cancer care. Little is known about the benefits of patient navigation during breast cancer treatment and survivorship. This systematic review evaluates the efficacy of patient navigation in improving treatment and survivorship outcomes in women with breast cancer.

METHODS

The review included experimental and quasi-experimental studies of patient navigation programs that target breast cancer treatment and breast cancer survivorship. Articles were systematically obtained through electronic database searches of PubMed/MEDLINE, PsycINFO, Web of Science, CINAHL, and Cochrane Library. The Effective Public Health Practice Project Quality Assessment Tool was used to evaluate the methodologic quality of individual studies.

RESULTS

Thirteen studies met the inclusion criteria. Most were of moderate to high quality. Outcomes targeted included timeliness of treatment initiation, adherence to cancer treatment, and adherence to post-treatment surveillance mammography. Heterogeneity of outcome assessments precluded a meta-analysis. Overall, results demonstrated that patient navigation increases surveillance mammography rates, but only minimal evidence was found with regard to its effectiveness in improving breast cancer treatment outcomes.

CONCLUSION

This study is the most comprehensive systematic review of patient navigation research focused on improving breast cancer treatment and survivorship. Minimal research has indicated that patient navigation may be effective for post-treatment surveillance; however, more studies are needed to draw definitive conclusions about the efficacy of patient navigation during and after cancer treatment.

Navigation programs, are they helpful for perioperative care with thyroid cancer patients?

The purpose of this study was to develop and evaluate a navigation program for patients with thyroid cancer. The navigation program was developed following an analysis of the unmet needs of patients who underwent surgery for thyroid cancer. Ninety-nine patients in the control group received usual care, and 95 in the navigation group were managed with a navigation program during the perioperative period. The effectiveness of the navigation program was assessed by administering a questionnaire to both groups. Overall satisfaction scores were significantly higher in the navigation than in the control group (p = .025), as were satisfaction scores on the continuity of information (p < .001), the continuity of management (p = .002), the continuity of relationships with healthcare providers (p<.001), and patient empowerment (p < .001). The newly developed navigation program for patients with thyroid cancer was effective in raising satisfaction levels and in actively managing the disease during the perioperative period.
