A Perfect Storm: Interventions – Closing the survival gap

Editor’s Note: This is the fourth installment of a five-part monthly series that will discuss the biologic, genomic, and health system factors that contribute to the racial survival disparity in breast cancer. The series was adapted from an article that originally appeared in CA: A Cancer Journal for Clinicians,1 a journal of the American Cancer Society. Eliminating racial disparities in cancer mortality through effective interventions has become an increasingly important imperative of federal, state, and community health care programs. This month’s column reviews interventions to close this survival gap.

 

Insurance

It has been posited that interventions aimed at providing insurance coverage to minority patients will be able to reduce racial health care disparities.2 Studies have indicated that women without insurance present with more-advanced disease,3,4 and are more likely to receive nonstandard treatment.5 However, outside of cancer care, a large study of Medicaid expansion in Oregon demonstrated that Medicaid coverage alone generated no significant improvement in measured physical health outcomes in the first 2 years.6 Thus, coverage alone does not ensure that patients will be able to navigate the health care system and that quality care will be provided.

In breast cancer, Hoffman et al.7 evaluated the effect of race and health insurance on diagnostic time, which was defined as the number of days from suspicious finding to diagnostic resolution (either no evidence of malignancy on diagnostic mammogram or definitive diagnosis by biopsy) in a large, urban setting. The authors’ hypothesis was that every insured patient would receive the same timely diagnosis as any other patient with equivalent insurance, regardless of race or ethnicity. The study found that non-Hispanic whites with government insurance had significantly shorter diagnostic times than did non-Hispanic African Americans with government insurance: The average diagnostic times were 12 and 39 days, respectively. In addition, privately insured non-Hispanic whites also had significantly shorter diagnostic times than did privately insured non-Hispanic African Americans (16 vs. 27 days). In addition, Short et al.8 demonstrated that when the health plan status was held constant in a retrospective study of 476 white patients and 99 African American patients with newly diagnosed breast cancer, African American patients had a higher mortality rate (8.1% vs. 3.6%) and were diagnosed at a later stage. Accordingly, interventions must go beyond just providing health insurance to minorities in order to have a significant impact on the mortality gap.

 

Patient education and physician communication

 

An underlying cause frequently cited for the delayed diagnosis and treatment of African American patients with breast cancer is a lack of patient education and physician communication. These elements are essential components of quality care. In a qualitative study of low-income, ethnically diverse women older than 40 years, Allen et al.9 identified salient themes differentiating women who received timely follow-up from those who did not. For the women who delayed follow-up, prominent themes were dissatisfaction with the communication of results, disrespect on the part of providers and clinical staff, logistical barriers to accessing services, anxiety and fear about a possible cancer diagnosis, and a lack of information about breast cancer screening and symptoms.

In another study, Masi and Gehlert10 employed focus group interviews of African American adults to characterize their perceptions of breast cancer treatment. The analysis revealed a core set of themes, including mistrust of the medical establishment and concern about the effect of racism on treatment quality; the researchers concluded that “in the eyes of many study participants, the issues of trust, race, and quality of care were closely intertwined.”10 Thus, this knot that is created by underlying issues of trust can be untied only by interventions that address improved physician communication and patient education.

Janz et al.11 examined racial differences in the adequacy of information and support for women with breast cancer. The researchers used survey data from a population of 1,766 women diagnosed with nonmetastatic breast cancer and reported to the Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry. The study found that across treatment- and survivorship-related issues, African American women desired more information than white women did. One of the explanations for the unmet information needs posited by the authors is a failure to provide culturally appropriate information related to health issues. This breakdown in patient education and communication was demonstrated by Hawley et al. to hold across providers and locations.12

Hawley et al.12 evaluated the association between minority patients’ knowledge of breast cancer treatment risks and benefits and provider characteristics and treatment locations. The provider characteristics included surgeon-level independent variables, such as breast cancer procedure volume and demographics (years in practice and sex). The treatment location variable was categorized into one of three groups: National Cancer Institute–designated cancer center, American College of Surgeons cancer program, or no specific cancer program. Provider characteristics and treatment locations are factors previously identified as being associated with high-quality care.

 

 

The study employed a multivariable regression to identify associations between patient, surgeon, and treatment-setting factors and accurate knowledge of the survival benefit and recurrence risk related to mastectomy and breast-conserving surgery with radiation. The authors found that minority women were significantly less likely to have adequate knowledge and more likely to be uncertain about recurrence risk than were white patients. In the multivariate logistic regression model, neither provider characteristics nor treatment setting attenuated observed racial disparities in knowledge. Quality health care depends on the ability to make an informed treatment decision. As the authors concluded, this study underscores the need for providers to communicate information effectively to all patients, and effective communication relies on the cultural competency of providers.13 Without effective, culturally competent communication, there are treatment delays and omissions that result in poor-quality cancer care. Currently, the research has established that these communication deficits are found across providers and treatment center types.

Patient Navigation

Patient navigation has been championed as a method of improving care in breast cancer by enhancing patient communication and education, and removing barriers to timely care. Patient navigation empowers patients to become knowledgeable about their own health and supports them through the course of care.14 Patient navigation programs have been developed to address the patient communication breakdowns and underuse and misuse of treatment among vulnerable populations, which were detailed earlier in this series and are thought to contribute to the racial mortality gap.15

A benefit of patient navigation has been suggested in studies evaluating the time to diagnosis and follow-up from an abnormal screening. Markossian et al.16 evaluated the efficacy of a Chicago-based cancer patient navigation program developed to reduce the time from abnormal screening to definitive diagnostic testing. The majority of patients in this study were Hispanic (66%) and African American (32%). Compared with controls without navigation, the breast navigation group had a shorter time to diagnostic resolution. Hoffman et al.17 evaluated patient navigation in the District of Columbia to determine its ability to reduce the breast cancer diagnostic time (number of days from abnormal screening to a definitive diagnosis). African American women comprised 48% of the study population. The investigators found that women in the navigation group reached their diagnostic resolution significantly faster than did other women. Among women with breast cancer, there was a nearly fourfold reduction in time to diagnostic resolution for women in the navigation group versus women without a navigator.

In a national multicenter study, Ko et al.14 were the first to evaluate whether patient navigation can improve the quality of breast cancer care. The authors hypothesized that breast cancer patients assigned a navigator would be more likely to receive recommended standard treatment than were those without a navigator. Three separate quality measures of breast cancer care, including initiation of antiestrogen therapy, radiation therapy, and chemotherapy, were evaluated. Study participants were racially and ethnically diverse, with a plurality being African American (37.5%). The study produced mixed results: Patients in the navigation group had a statistically higher likelihood of receiving antiestrogen therapy than were non–navigated controls, but navigation patients eligible for radiation therapy were no more likely to receive it than were controls. The initiation of chemotherapy could not be accurately assessed because of a limited sample size. The study concluded that navigation alone does not remove all of the barriers to quality care for breast cancer patients, and barriers are diverse and potentially specific to the modality of treatment.

A study by Tejeda et al.18 used a systematic framework to characterize barriers faced by minority patients with breast and cervical cancer. The investigators categorized barriers as intrapersonal (defined by characteristics of the individual, such as knowledge, belief, attitudes, and transportation and financial barriers), interpersonal (defined by processes that involve other people, such as social support systems, child care, and employment issues), or institutional (defined by characteristics and policies of organizations). The authors found that although navigators were able to easily resolve intrapersonal barriers, ongoing navigation was needed to address institutional barriers. Thus, patient navigation in a vacuum does not work, and it is only in examining the entire health care system that changes can be implemented to eliminate barriers to quality care and close the racial mortality chasm.

System Change

To this effect, Clarke et al.19 performed a review of the disparities intervention literature to understand which interventions are being evaluated to improve minority health. The authors found that the majority of such interventions are focused on changing the patient rather than the system that serves her, with the most common strategy being education and training (37% of strategies studied). Interventions aimed at health care system improvements were surprisingly few, with the responsibility for change resting with the patient rather than the care delivery system. Interventions incorporating community involvement were also severely lacking and reflected only 6.5% of the reviewed intervention tactics. The majority of interventions failed to involve major stakeholders, including providers, health care institutions, community organizers, and policy makers, and accordingly, were unlikely to succeed in creating meaningful change.

 

 

In breast cancer, there have been examples of successful system-based approaches to reducing the racial mortality disparity. At New York area hospitals, Bickell et al.20 implemented a tracking and feedback registry to close the referral loop between surgeons and oncologists to decrease the underuse of valuable adjuvant treatments.

The intervention targeted important quality issues in both communication (the breakdown in dialogue among providers of different specialties and between providers and patients) and the underuse of adjuvant treatment in minorities. The approach was designed to address failures in the health care system through the involvement of leadership from pathology, surgery, and oncology. The intervention also incorporated technology, with tracking software prompting contact with patients who had failed to follow up. Among African American and Hispanic women, there were statistically significant decreases in the underuse of radiotherapy (23% before the intervention vs. 10% after the intervention), chemotherapy (26% vs. 6%), and hormonal therapy (27% vs. 11%). After the intervention, minority race was no longer a risk factor for low rates of oncology consultation or underuse of adjuvant therapy. Interestingly, four of the six hospitals involved in this study had a patient navigation system in place; however, as discussed, the navigation system alone was not enough to address the system failures that led to disparities in care.

Ansell et al.21 also described a system-based approach to reducing the breast cancer mortality disparity in Chicago. The Metropolitan Chicago Breast Cancer Task Force comprised 102 individuals and 74 Chicago area organizations to address the growing disparity in breast cancer mortality between African American and white patients. The task force identified a number of themes underlying the disparity gap, including a need for breast cancer education and outreach programs for African American women, a broken mammography process leading to quality differences between African American and white patients, and a number of barriers to diagnosis and treatment, including fear, a lack of primary care, the burden of insurance copays/deductibles, and the noncompletion of treatment for social and economic reasons. After identifying these underlying causes, the task force proposed that addressing one aspect of the health care system would not correct the problem, but rather quality improvement initiatives would have to occur across the continuum of care for breast cancer.

In Delaware, such a broad system-based intervention was implemented to eliminate health disparities in colorectal cancer.22 Delaware created a comprehensive statewide colorectal screening and treatment program, combining many of the interventions discussed previously, including insurance coverage, patient education and communication, and patient navigation, to address the entire health care system and its treatment of African Americans with colorectal cancer. The state also partnered with underserved community organizations to tailor programs locally and create targeted marketing campaigns.

The results of this system-based approach were impressive, with screening rates among African American increasing from 48% to 74% and equaling the rate among whites. In addition, among African American patients, the percentage diagnosed at advanced and regional stages declined from 79% to 40%, and the percentage diagnosed at a local stage increased from 16% to 50%. Most importantly, the mortality rate declined by 42% for African Americans, resulting in a rate almost equal to that among whites. Significantly, this program was also found to be economically viable, because the cost savings from reduced cancer incidence and the stage shift to cancers requiring less-aggressive treatment offset the program cost. As the authors concluded, this model of a comprehensive, system-wide approach to the racial mortality difference would lend itself to other cancers, and more research is needed to assess and build such an approach to breast cancer.

As discussed in the aforementioned studies, multifaceted interventions that address all stakeholders are needed to close the racial survival disparity in breast cancer. In the final installment of this series, we will address how the changing care models ushered in by the Patient Protection and Affordable Care Act have the potential to advance this agenda of creating an intervention that works across the breast cancer care continuum to reduce disparities.

Editor’s Note: This is the fourth installment of a five-part monthly series that will discuss the biologic, genomic, and health system factors that contribute to the racial survival disparity in breast cancer. The series was adapted from an article that originally appeared in CA: A Cancer Journal for Clinicians,1 a journal of the American Cancer Society. Eliminating racial disparities in cancer mortality through effective interventions has become an increasingly important imperative of federal, state, and community health care programs. This month’s column reviews interventions to close this survival gap.

 

Insurance

It has been posited that interventions aimed at providing insurance coverage to minority patients will be able to reduce racial health care disparities.2 Studies have indicated that women without insurance present with more-advanced disease,3,4 and are more likely to receive nonstandard treatment.5 However, outside of cancer care, a large study of Medicaid expansion in Oregon demonstrated that Medicaid coverage alone generated no significant improvement in measured physical health outcomes in the first 2 years.6 Thus, coverage alone does not ensure that patients will be able to navigate the health care system and that quality care will be provided.

In breast cancer, Hoffman et al.7 evaluated the effect of race and health insurance on diagnostic time, which was defined as the number of days from suspicious finding to diagnostic resolution (either no evidence of malignancy on diagnostic mammogram or definitive diagnosis by biopsy) in a large, urban setting. The authors’ hypothesis was that every insured patient would receive the same timely diagnosis as any other patient with equivalent insurance, regardless of race or ethnicity. The study found that non-Hispanic whites with government insurance had significantly shorter diagnostic times than did non-Hispanic African Americans with government insurance: The average diagnostic times were 12 and 39 days, respectively. In addition, privately insured non-Hispanic whites also had significantly shorter diagnostic times than did privately insured non-Hispanic African Americans (16 vs. 27 days). In addition, Short et al.8 demonstrated that when the health plan status was held constant in a retrospective study of 476 white patients and 99 African American patients with newly diagnosed breast cancer, African American patients had a higher mortality rate (8.1% vs. 3.6%) and were diagnosed at a later stage. Accordingly, interventions must go beyond just providing health insurance to minorities in order to have a significant impact on the mortality gap.

 

Patient education and physician communication

 

An underlying cause frequently cited for the delayed diagnosis and treatment of African American patients with breast cancer is a lack of patient education and physician communication. These elements are essential components of quality care. In a qualitative study of low-income, ethnically diverse women older than 40 years, Allen et al.9 identified salient themes differentiating women who received timely follow-up from those who did not. For the women who delayed follow-up, prominent themes were dissatisfaction with the communication of results, disrespect on the part of providers and clinical staff, logistical barriers to accessing services, anxiety and fear about a possible cancer diagnosis, and a lack of information about breast cancer screening and symptoms.

In another study, Masi and Gehlert10 employed focus group interviews of African American adults to characterize their perceptions of breast cancer treatment. The analysis revealed a core set of themes, including mistrust of the medical establishment and concern about the effect of racism on treatment quality; the researchers concluded that “in the eyes of many study participants, the issues of trust, race, and quality of care were closely intertwined.”10 Thus, this knot that is created by underlying issues of trust can be untied only by interventions that address improved physician communication and patient education.

Janz et al.11 examined racial differences in the adequacy of information and support for women with breast cancer. The researchers used survey data from a population of 1,766 women diagnosed with nonmetastatic breast cancer and reported to the Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry. The study found that across treatment- and survivorship-related issues, African American women desired more information than white women did. One of the explanations for the unmet information needs posited by the authors is a failure to provide culturally appropriate information related to health issues. This breakdown in patient education and communication was demonstrated by Hawley et al. to hold across providers and locations.12

Hawley et al.12 evaluated the association between minority patients’ knowledge of breast cancer treatment risks and benefits and provider characteristics and treatment locations. The provider characteristics included surgeon-level independent variables, such as breast cancer procedure volume and demographics (years in practice and sex). The treatment location variable was categorized into one of three groups: National Cancer Institute–designated cancer center, American College of Surgeons cancer program, or no specific cancer program. Provider characteristics and treatment locations are factors previously identified as being associated with high-quality care.

 

 

The study employed a multivariable regression to identify associations between patient, surgeon, and treatment-setting factors and accurate knowledge of the survival benefit and recurrence risk related to mastectomy and breast-conserving surgery with radiation. The authors found that minority women were significantly less likely to have adequate knowledge and more likely to be uncertain about recurrence risk than were white patients. In the multivariate logistic regression model, neither provider characteristics nor treatment setting attenuated observed racial disparities in knowledge. Quality health care depends on the ability to make an informed treatment decision. As the authors concluded, this study underscores the need for providers to communicate information effectively to all patients, and effective communication relies on the cultural competency of providers.13 Without effective, culturally competent communication, there are treatment delays and omissions that result in poor-quality cancer care. Currently, the research has established that these communication deficits are found across providers and treatment center types.

Patient Navigation

Patient navigation has been championed as a method of improving care in breast cancer by enhancing patient communication and education, and removing barriers to timely care. Patient navigation empowers patients to become knowledgeable about their own health and supports them through the course of care.14 Patient navigation programs have been developed to address the patient communication breakdowns and underuse and misuse of treatment among vulnerable populations, which were detailed earlier in this series and are thought to contribute to the racial mortality gap.15

A benefit of patient navigation has been suggested in studies evaluating the time to diagnosis and follow-up from an abnormal screening. Markossian et al.16 evaluated the efficacy of a Chicago-based cancer patient navigation program developed to reduce the time from abnormal screening to definitive diagnostic testing. The majority of patients in this study were Hispanic (66%) and African American (32%). Compared with controls without navigation, the breast navigation group had a shorter time to diagnostic resolution. Hoffman et al.17 evaluated patient navigation in the District of Columbia to determine its ability to reduce the breast cancer diagnostic time (number of days from abnormal screening to a definitive diagnosis). African American women comprised 48% of the study population. The investigators found that women in the navigation group reached their diagnostic resolution significantly faster than did other women. Among women with breast cancer, there was a nearly fourfold reduction in time to diagnostic resolution for women in the navigation group versus women without a navigator.

In a national multicenter study, Ko et al.14 were the first to evaluate whether patient navigation can improve the quality of breast cancer care. The authors hypothesized that breast cancer patients assigned a navigator would be more likely to receive recommended standard treatment than were those without a navigator. Three separate quality measures of breast cancer care, including initiation of antiestrogen therapy, radiation therapy, and chemotherapy, were evaluated. Study participants were racially and ethnically diverse, with a plurality being African American (37.5%). The study produced mixed results: Patients in the navigation group had a statistically higher likelihood of receiving antiestrogen therapy than were non–navigated controls, but navigation patients eligible for radiation therapy were no more likely to receive it than were controls. The initiation of chemotherapy could not be accurately assessed because of a limited sample size. The study concluded that navigation alone does not remove all of the barriers to quality care for breast cancer patients, and barriers are diverse and potentially specific to the modality of treatment.

A study by Tejeda et al.18 used a systematic framework to characterize barriers faced by minority patients with breast and cervical cancer. The investigators categorized barriers as intrapersonal (defined by characteristics of the individual, such as knowledge, belief, attitudes, and transportation and financial barriers), interpersonal (defined by processes that involve other people, such as social support systems, child care, and employment issues), or institutional (defined by characteristics and policies of organizations). The authors found that although navigators were able to easily resolve intrapersonal barriers, ongoing navigation was needed to address institutional barriers. Thus, patient navigation in a vacuum does not work, and it is only in examining the entire health care system that changes can be implemented to eliminate barriers to quality care and close the racial mortality chasm.

System Change

To this effect, Clarke et al.19 performed a review of the disparities intervention literature to understand which interventions are being evaluated to improve minority health. The authors found that the majority of such interventions are focused on changing the patient rather than the system that serves her, with the most common strategy being education and training (37% of strategies studied). Interventions aimed at health care system improvements were surprisingly few, with the responsibility for change resting with the patient rather than the care delivery system. Interventions incorporating community involvement were also severely lacking and reflected only 6.5% of the reviewed intervention tactics. The majority of interventions failed to involve major stakeholders, including providers, health care institutions, community organizers, and policy makers, and accordingly, were unlikely to succeed in creating meaningful change.

 

 

In breast cancer, there have been examples of successful system-based approaches to reducing the racial mortality disparity. At New York area hospitals, Bickell et al.20 implemented a tracking and feedback registry to close the referral loop between surgeons and oncologists to decrease the underuse of valuable adjuvant treatments.

The intervention targeted important quality issues in both communication (the breakdown in dialogue among providers of different specialties and between providers and patients) and the underuse of adjuvant treatment in minorities. The approach was designed to address failures in the health care system through the involvement of leadership from pathology, surgery, and oncology. The intervention also incorporated technology, with tracking software prompting contact with patients who had failed to follow up. Among African American and Hispanic women, there were statistically significant decreases in the underuse of radiotherapy (23% before the intervention vs. 10% after the intervention), chemotherapy (26% vs. 6%), and hormonal therapy (27% vs. 11%). After the intervention, minority race was no longer a risk factor for low rates of oncology consultation or underuse of adjuvant therapy. Interestingly, four of the six hospitals involved in this study had a patient navigation system in place; however, as discussed, the navigation system alone was not enough to address the system failures that led to disparities in care.

Ansell et al.21 also described a system-based approach to reducing the breast cancer mortality disparity in Chicago. The Metropolitan Chicago Breast Cancer Task Force comprised 102 individuals and 74 Chicago area organizations to address the growing disparity in breast cancer mortality between African American and white patients. The task force identified a number of themes underlying the disparity gap, including a need for breast cancer education and outreach programs for African American women, a broken mammography process leading to quality differences between African American and white patients, and a number of barriers to diagnosis and treatment, including fear, a lack of primary care, the burden of insurance copays/deductibles, and the noncompletion of treatment for social and economic reasons. After identifying these underlying causes, the task force proposed that addressing one aspect of the health care system would not correct the problem, but rather quality improvement initiatives would have to occur across the continuum of care for breast cancer.

In Delaware, such a broad system-based intervention was implemented to eliminate health disparities in colorectal cancer.22 Delaware created a comprehensive statewide colorectal screening and treatment program, combining many of the interventions discussed previously, including insurance coverage, patient education and communication, and patient navigation, to address the entire health care system and its treatment of African Americans with colorectal cancer. The state also partnered with underserved community organizations to tailor programs locally and create targeted marketing campaigns.

The results of this system-based approach were impressive, with screening rates among African American increasing from 48% to 74% and equaling the rate among whites. In addition, among African American patients, the percentage diagnosed at advanced and regional stages declined from 79% to 40%, and the percentage diagnosed at a local stage increased from 16% to 50%. Most importantly, the mortality rate declined by 42% for African Americans, resulting in a rate almost equal to that among whites. Significantly, this program was also found to be economically viable, because the cost savings from reduced cancer incidence and the stage shift to cancers requiring less-aggressive treatment offset the program cost. As the authors concluded, this model of a comprehensive, system-wide approach to the racial mortality difference would lend itself to other cancers, and more research is needed to assess and build such an approach to breast cancer.

As discussed in the aforementioned studies, multifaceted interventions that address all stakeholders are needed to close the racial survival disparity in breast cancer. In the final installment of this series, we will address how the changing care models ushered in by the Patient Protection and Affordable Care Act have the potential to advance this agenda of creating an intervention that works across the breast cancer care continuum to reduce disparities.

Editor’s Note: This is the fourth installment of a five-part monthly series that will discuss the biologic, genomic, and health system factors that contribute to the racial survival disparity in breast cancer. The series was adapted from an article that originally appeared in CA: A Cancer Journal for Clinicians,1 a journal of the American Cancer Society. Eliminating racial disparities in cancer mortality through effective interventions has become an increasingly important imperative of federal, state, and community health care programs. This month’s column reviews interventions to close this survival gap.

 

Insurance

It has been posited that interventions aimed at providing insurance coverage to minority patients will be able to reduce racial health care disparities.2 Studies have indicated that women without insurance present with more-advanced disease,3,4 and are more likely to receive nonstandard treatment.5 However, outside of cancer care, a large study of Medicaid expansion in Oregon demonstrated that Medicaid coverage alone generated no significant improvement in measured physical health outcomes in the first 2 years.6 Thus, coverage alone does not ensure that patients will be able to navigate the health care system and that quality care will be provided.

In breast cancer, Hoffman et al.7 evaluated the effect of race and health insurance on diagnostic time, which was defined as the number of days from suspicious finding to diagnostic resolution (either no evidence of malignancy on diagnostic mammogram or definitive diagnosis by biopsy) in a large, urban setting. The authors’ hypothesis was that every insured patient would receive the same timely diagnosis as any other patient with equivalent insurance, regardless of race or ethnicity. The study found that non-Hispanic whites with government insurance had significantly shorter diagnostic times than did non-Hispanic African Americans with government insurance: The average diagnostic times were 12 and 39 days, respectively. In addition, privately insured non-Hispanic whites also had significantly shorter diagnostic times than did privately insured non-Hispanic African Americans (16 vs. 27 days). In addition, Short et al.8 demonstrated that when the health plan status was held constant in a retrospective study of 476 white patients and 99 African American patients with newly diagnosed breast cancer, African American patients had a higher mortality rate (8.1% vs. 3.6%) and were diagnosed at a later stage. Accordingly, interventions must go beyond just providing health insurance to minorities in order to have a significant impact on the mortality gap.

 

Patient education and physician communication

 

An underlying cause frequently cited for the delayed diagnosis and treatment of African American patients with breast cancer is a lack of patient education and physician communication. These elements are essential components of quality care. In a qualitative study of low-income, ethnically diverse women older than 40 years, Allen et al.9 identified salient themes differentiating women who received timely follow-up from those who did not. For the women who delayed follow-up, prominent themes were dissatisfaction with the communication of results, disrespect on the part of providers and clinical staff, logistical barriers to accessing services, anxiety and fear about a possible cancer diagnosis, and a lack of information about breast cancer screening and symptoms.

In another study, Masi and Gehlert10 employed focus group interviews of African American adults to characterize their perceptions of breast cancer treatment. The analysis revealed a core set of themes, including mistrust of the medical establishment and concern about the effect of racism on treatment quality; the researchers concluded that “in the eyes of many study participants, the issues of trust, race, and quality of care were closely intertwined.”10 Thus, this knot that is created by underlying issues of trust can be untied only by interventions that address improved physician communication and patient education.

Janz et al.11 examined racial differences in the adequacy of information and support for women with breast cancer. The researchers used survey data from a population of 1,766 women diagnosed with nonmetastatic breast cancer and reported to the Los Angeles County Surveillance, Epidemiology, and End Results (SEER) registry. The study found that across treatment- and survivorship-related issues, African American women desired more information than white women did. One of the explanations for the unmet information needs posited by the authors is a failure to provide culturally appropriate information related to health issues. This breakdown in patient education and communication was demonstrated by Hawley et al. to hold across providers and locations.12

Hawley et al.12 evaluated the association between minority patients’ knowledge of breast cancer treatment risks and benefits and provider characteristics and treatment locations. The provider characteristics included surgeon-level independent variables, such as breast cancer procedure volume and demographics (years in practice and sex). The treatment location variable was categorized into one of three groups: National Cancer Institute–designated cancer center, American College of Surgeons cancer program, or no specific cancer program. Provider characteristics and treatment locations are factors previously identified as being associated with high-quality care.

 

 

The study employed a multivariable regression to identify associations between patient, surgeon, and treatment-setting factors and accurate knowledge of the survival benefit and recurrence risk related to mastectomy and breast-conserving surgery with radiation. The authors found that minority women were significantly less likely to have adequate knowledge and more likely to be uncertain about recurrence risk than were white patients. In the multivariate logistic regression model, neither provider characteristics nor treatment setting attenuated observed racial disparities in knowledge. Quality health care depends on the ability to make an informed treatment decision. As the authors concluded, this study underscores the need for providers to communicate information effectively to all patients, and effective communication relies on the cultural competency of providers.13 Without effective, culturally competent communication, there are treatment delays and omissions that result in poor-quality cancer care. Currently, the research has established that these communication deficits are found across providers and treatment center types.

Patient Navigation

Patient navigation has been championed as a method of improving care in breast cancer by enhancing patient communication and education, and removing barriers to timely care. Patient navigation empowers patients to become knowledgeable about their own health and supports them through the course of care.14 Patient navigation programs have been developed to address the patient communication breakdowns and underuse and misuse of treatment among vulnerable populations, which were detailed earlier in this series and are thought to contribute to the racial mortality gap.15

A benefit of patient navigation has been suggested in studies evaluating the time to diagnosis and follow-up from an abnormal screening. Markossian et al.16 evaluated the efficacy of a Chicago-based cancer patient navigation program developed to reduce the time from abnormal screening to definitive diagnostic testing. The majority of patients in this study were Hispanic (66%) and African American (32%). Compared with controls without navigation, the breast navigation group had a shorter time to diagnostic resolution. Hoffman et al.17 evaluated patient navigation in the District of Columbia to determine its ability to reduce the breast cancer diagnostic time (number of days from abnormal screening to a definitive diagnosis). African American women comprised 48% of the study population. The investigators found that women in the navigation group reached their diagnostic resolution significantly faster than did other women. Among women with breast cancer, there was a nearly fourfold reduction in time to diagnostic resolution for women in the navigation group versus women without a navigator.

In a national multicenter study, Ko et al.14 were the first to evaluate whether patient navigation can improve the quality of breast cancer care. The authors hypothesized that breast cancer patients assigned a navigator would be more likely to receive recommended standard treatment than were those without a navigator. Three separate quality measures of breast cancer care, including initiation of antiestrogen therapy, radiation therapy, and chemotherapy, were evaluated. Study participants were racially and ethnically diverse, with a plurality being African American (37.5%). The study produced mixed results: Patients in the navigation group had a statistically higher likelihood of receiving antiestrogen therapy than were non–navigated controls, but navigation patients eligible for radiation therapy were no more likely to receive it than were controls. The initiation of chemotherapy could not be accurately assessed because of a limited sample size. The study concluded that navigation alone does not remove all of the barriers to quality care for breast cancer patients, and barriers are diverse and potentially specific to the modality of treatment.

A study by Tejeda et al.18 used a systematic framework to characterize barriers faced by minority patients with breast and cervical cancer. The investigators categorized barriers as intrapersonal (defined by characteristics of the individual, such as knowledge, belief, attitudes, and transportation and financial barriers), interpersonal (defined by processes that involve other people, such as social support systems, child care, and employment issues), or institutional (defined by characteristics and policies of organizations). The authors found that although navigators were able to easily resolve intrapersonal barriers, ongoing navigation was needed to address institutional barriers. Thus, patient navigation in a vacuum does not work, and it is only in examining the entire health care system that changes can be implemented to eliminate barriers to quality care and close the racial mortality chasm.

System Change

To this effect, Clarke et al.19 performed a review of the disparities intervention literature to understand which interventions are being evaluated to improve minority health. The authors found that the majority of such interventions are focused on changing the patient rather than the system that serves her, with the most common strategy being education and training (37% of strategies studied). Interventions aimed at health care system improvements were surprisingly few, with the responsibility for change resting with the patient rather than the care delivery system. Interventions incorporating community involvement were also severely lacking and reflected only 6.5% of the reviewed intervention tactics. The majority of interventions failed to involve major stakeholders, including providers, health care institutions, community organizers, and policy makers, and accordingly, were unlikely to succeed in creating meaningful change.

 

 

In breast cancer, there have been examples of successful system-based approaches to reducing the racial mortality disparity. At New York area hospitals, Bickell et al.20 implemented a tracking and feedback registry to close the referral loop between surgeons and oncologists to decrease the underuse of valuable adjuvant treatments.

The intervention targeted important quality issues in both communication (the breakdown in dialogue among providers of different specialties and between providers and patients) and the underuse of adjuvant treatment in minorities. The approach was designed to address failures in the health care system through the involvement of leadership from pathology, surgery, and oncology. The intervention also incorporated technology, with tracking software prompting contact with patients who had failed to follow up. Among African American and Hispanic women, there were statistically significant decreases in the underuse of radiotherapy (23% before the intervention vs. 10% after the intervention), chemotherapy (26% vs. 6%), and hormonal therapy (27% vs. 11%). After the intervention, minority race was no longer a risk factor for low rates of oncology consultation or underuse of adjuvant therapy. Interestingly, four of the six hospitals involved in this study had a patient navigation system in place; however, as discussed, the navigation system alone was not enough to address the system failures that led to disparities in care.

Ansell et al.21 also described a system-based approach to reducing the breast cancer mortality disparity in Chicago. The Metropolitan Chicago Breast Cancer Task Force comprised 102 individuals and 74 Chicago area organizations to address the growing disparity in breast cancer mortality between African American and white patients. The task force identified a number of themes underlying the disparity gap, including a need for breast cancer education and outreach programs for African American women, a broken mammography process leading to quality differences between African American and white patients, and a number of barriers to diagnosis and treatment, including fear, a lack of primary care, the burden of insurance copays/deductibles, and the noncompletion of treatment for social and economic reasons. After identifying these underlying causes, the task force proposed that addressing one aspect of the health care system would not correct the problem, but rather quality improvement initiatives would have to occur across the continuum of care for breast cancer.

In Delaware, such a broad system-based intervention was implemented to eliminate health disparities in colorectal cancer.22 Delaware created a comprehensive statewide colorectal screening and treatment program, combining many of the interventions discussed previously, including insurance coverage, patient education and communication, and patient navigation, to address the entire health care system and its treatment of African Americans with colorectal cancer. The state also partnered with underserved community organizations to tailor programs locally and create targeted marketing campaigns.

The results of this system-based approach were impressive, with screening rates among African American increasing from 48% to 74% and equaling the rate among whites. In addition, among African American patients, the percentage diagnosed at advanced and regional stages declined from 79% to 40%, and the percentage diagnosed at a local stage increased from 16% to 50%. Most importantly, the mortality rate declined by 42% for African Americans, resulting in a rate almost equal to that among whites. Significantly, this program was also found to be economically viable, because the cost savings from reduced cancer incidence and the stage shift to cancers requiring less-aggressive treatment offset the program cost. As the authors concluded, this model of a comprehensive, system-wide approach to the racial mortality difference would lend itself to other cancers, and more research is needed to assess and build such an approach to breast cancer.

As discussed in the aforementioned studies, multifaceted interventions that address all stakeholders are needed to close the racial survival disparity in breast cancer. In the final installment of this series, we will address how the changing care models ushered in by the Patient Protection and Affordable Care Act have the potential to advance this agenda of creating an intervention that works across the breast cancer care continuum to reduce disparities.
