Black patients with lung cancer<\/span> are likely to die sooner than white patients. Research going back two decades shows that these racial differences, or disparities, exist in part because black patients with lung cancer that is diagnosed at an early stage are less likely to be treated<\/a><\/span> for the cancer.<\/p>\n

New findings from a clinical study funded in part by NCI show that use of a multipronged approach designed to address some of the underlying causes of these disparities may help to reduce them. The approach not only eliminated treatment gaps between black and white patients with early-stage lung cancer<\/a>,<\/span> but also improved treatment rates for all patients.<\/p>\n

The three-pronged approach included: a real-time warning system tied to electronic health records, to keep patients from falling through the cracks; feedback to clinical teams on treatment completion rates for black and white patients; and trained nurse navigators to engage with patients to identify and resolve barriers to care.<\/p>\n

The results, published February 4 in Cancer Medicine<\/em>, \u201care really promising,\u201d said Christopher Lathan, M.D., M.P.H., an oncologist at Dana-Farber Cancer Institute who studies racial disparities in lung cancer treatment but was not involved with the study.<\/p>\n

\u201cThis is a great example of a multilevel approach\u00a0that tries to address many different factors that contribute to racial disparities,\u201d Dr. Lathan said. \u201cIt\u2019s the type of intervention that we need to see tested and published, and hopefully expanded and confirmed going forward.\u201d<\/p>\n

Multiple Factors Contribute to Disparities<\/h2>\n

Treatment disparities between black and white patients with lung cancer<\/a> occur for multiple reasons, said the new study’s senior author, Samuel Cykert, M.D., of the UNC Lineberger Comprehensive Cancer Center in North Carolina.<\/p>\n

In 2006, for example, Dr. Lathan and his colleagues reported that black patients with early-stage lung cancer are less likely than white patients to have surgery recommended<\/a><\/span> and more likely to refuse surgery, despite having similar access to care.\u00a0And a 2010 study led by Dr. Cykert found that black patients with early-stage lung cancer who had two or more co-occurring health problems\u2014<\/span>such as a heart condition or diabetes\u2014<\/span>almost never had surgery for the cancer<\/a><\/span>, despite the fact that these conditions are not good medical reasons for a person not to have surgery, he said.<\/p>\n

\u201cDoctors were less willing to take the same treatment risks with patients who were [racially] different from them,\u201d Dr. Cykert said. This may be due to implicit bias\u2014attitudes or stereotypes that affect people\u2019s understanding, actions, and decisions in an unconscious manner.<\/p>\n

The 2010 study also found that black patients who did not have a regular source of medical care tended to trust physicians less or have communication problems with physicians, leading them to drop out of care completely. Denial of their cancer diagnosis also played a role for some patients.<\/p>\n

Addressing Barriers to Care and Raising Awareness<\/strong><\/h2>\n

Dr. Cykert and his colleagues designed their approach, or intervention, to address multiple underlying causes of treatment disparities. They did so with input from the Greensboro Health Disparities Collaborative, an academic\u2013community partnership formed in 2003 to better understand and reduce racial and ethnic health disparities.<\/p>\n

Nurse patient navigators<\/a> involved in the study, as well as staff at the five participating cancer centers\u2014<\/span>two of which were community centers\u2014<\/span>took part in health equity education and training sessions.<\/p>\n

The real-time warning system pulled data from electronic health records daily and delivered alerts to nurse navigators when a patient missed a scheduled appointment or did not reach an expected care milestone, such as having potentially curative treatment with surgery or radiation scheduled within 90 days of their initial visit.<\/p>\n

If a patient missed an appointment, a nurse navigator who had established an initial relationship with the patient would then contact the patient to identify and help resolve barriers to care, Dr. Cykert said. If a treatment milestone was missed, the navigator alerted a \u201cphysician champion\u201d\u2014a doctor who engaged the clinical team and discussed possible remedies.<\/p>\n

The clinical team also received race-specific feedback on treatment completion rates \u201cso that they could be more aware of racial disparity and address it in ongoing care for patients,\u201d said Matthew Manning, M.D., of Cone Health Cancer Center in Greensboro, NC, one of the physician champions and study coauthor.<\/p>\n

\u201cMany physicians are not aware of implicit bias in their own practice, or that implicit bias from caregivers across the continuum of care<\/a> contributes to racial disparity,\u201d Dr. Manning continued.<\/p>\n

\u201cThere is also a lack of awareness of barriers to access to care that fall more heavily on underserved populations,\u201d he said, such as the lack of access to reliable transportation.<\/p>\n

Black and White Patients Benefitted<\/h2>\n

The study enrolled 130 black patients and 277 white patients newly diagnosed with early-stage (stage I or II) non-small cell lung cancer (NSCLC)<\/a><\/span> at participating\u00a0centers. Of those patients, 114 black patients and 246 white patients completed the intervention.<\/p>\n

The team compared the rates for receiving surgery or radiation for patients in the study with the rates of those treatments in what the researchers called a baseline control group: all patients diagnosed with early-stage NSCLC from the five participating centers during the 6-year period before the study started.<\/p>\n

In the baseline control group, 78% of white patients and 69% of black patients completed treatment with either surgery or radiation. By contrast, 96.5% of black patients and 95% of white patients in the study completed treatment.<\/p>\n

In other words, Dr. Manning said, \u201cThis study, by trying to close the gap between black and white patients, ended up improving treatment for everyone.\u201d<\/p>\n

To make sure that any improvement seen in the study participants was due to the intervention rather than something else, such as a trend in treatment that had developed over time, the team also looked at treatment completion rates in a second control group, Dr. Cykert explained. This group consisted of people with newly diagnosed early-stage lung cancer from two of the five participating centers who were seen at the same time as the patients in the study group but were not enrolled in the study.<\/p>\n

Treatment rates for both black and white patients in the study were better than those of patients in this second control group, the researchers found.<\/p>\n

The team established the two outside control groups rather than randomly assigning study patients to the intervention or a control group that received no intervention because they felt it was unethical not to provide the intervention to all patients who agreed to participate in the study.<\/p>\n

A Potential Blueprint for Reducing Disparities<\/h2>\n

If the multilevel approach used in this study can be replicated and shown to be effective elsewhere, \u201cthen you have a blueprint that you can use to alleviate disparities in other areas of cancer care,\u201d Dr. Lathan said.<\/p>\n

Implementing the approach more widely would not be too difficult or costly because of the widespread use of electronic health records and the growing use of patient navigators in cancer treatment centers, Dr. Cykert believes. He acknowledged, however, that some special training would be needed.<\/p>\n

\u201cWhat\u2019s great about this approach is that it\u2019s using a multilevel intervention to try to address many different factors that could be contributing to racial disparities in care,\u201d Dr. Lathan said. \u201cThe key to implementing it more widely is to figure out which of the three components of the intervention is the most effective, or if it\u2019s a combination of the three,\u201d he said.<\/p>\n

\u201cThis intervention helped everybody and that shouldn\u2019t be minimized,\u201d Dr. Lathan added.<\/p>\n

The involvement of community cancer centers in the study was important because most cancer care is delivered in community health programs rather than at universities and other academic cancer centers, Dr. Manning said.<\/p>\n

\u201cTo get equal health outcomes\u2014that is, health equity\u2014we need to address cultural differences, access to care, and other issues that are different among different races and populations,\u201d Dr. Manning concluded. \u201cMaking clinicians more aware of institutional racial disparity allows us to begin to address some of those barriers to care and move beyond health equality, which provides the same care to all patients, toward health equity.\u201d<\/p>\n
