Banaji and Anthony G. Greenwald Implicit Associations Test 21-Day Racial Equity Challenge TRANSCRIPT Dr. Nimish Mohile: We had a patient a few years ago who had presented to our clinic, who ended up having a diagnosis of primary central nervous system lymphoma, and she was a young black woman, and it took about nine months for her to get that diagnosis. She had gone into multiple emergency rooms, she was only 22, had not had prior interaction with the medical system, but based on some of her socioeconomic demographics, her skin color, she was never given the kinds of testing that any other patient I think should have gotten at that time. Dr. Alissa Thomas: Hello, and welcome to another episode of ASCO Education podcast. Today's topic is, 'Implicit racial bias and its impact on patient care.' My name is Alissa Thomas, and I'm a Neurologist and Neuro-Oncologist at the University of Vermont College of Medicine. I'm delighted to introduce our two guest speakers; Dr. Lauren Hamel, who is an Associate Professor of Communication and Behavioral Oncology at Wayne State University, and the Co-program Leader of the Population Studies and Disparities Research Program of the Karmanos Cancer Institute. Her ongoing research explores racial attitudes in non-verbal behavior of oncology patients and physicians, and how those behaviors influence treatment decisions. Dr. Nimish Mohile is a Professor of Neurology and Oncology at The University of Rochester. He also serves as the Diversity Officer, Associate Chair for Career Development and Leadership, and Neuro-Oncology Division Chief. I'll get us started with the first question, really a definition. What do we mean by the term, 'implicit racial bias'? Dr. Lauren Hamel: I'm happy to go first. I think understanding what the definition of what implicit racial bias is is really important. You know, for good or for ill, over the last few years, it's gotten a lot more attention. And I think what's important to remember about it is that it's not a cognizant or a conscious bias, and it really is implicit, and it really is more of an association than it is anything else. It's sort of like the built-up associations that we have for anything. You know, could be race, could be gender, any number of demographics, or other factors that make our lives as humans. So, you know, associating certain aspects of people with positive or negative valuations. I think when we're talking about implicit racial bias, it's kind of like the gut associations we have for members of different racial groups. So often, it's kind of paired with "white is good, black is bad." It's a very rudimentary description of it, but that's a real kind of basic association that this kind of definition is built around. Dr. Nimish Mohile: Yeah, I would agree with that. I think that's a great discussion of what this is. I think it's really important for us to remember that these are really ingrained behaviors. It's, based on, you know, how we've been socialized and conditioned. And I think it's helpful to also put it in the framework of knowing that we all have some biases, we all probably have racial biases, and age biases, and other kinds of biases, and there's no sort of good or bad about having these biases. And the important part of this is, how do we recognize some of the biases that we have so that we can be more conscious about how we might fix those or think differently about the patients that we're seeing so that it doesn't result in actions that can be harmful. Dr. Lauren Hamel: Yeah, I agree with everything that Dr. Mohile just added. It is these ingrained associations. Really, it isn't about blaming ourselves for them because it's kind of the result of how our brains are structured. But to his point, it's once we know that we have them, and you know, we have data showing how they affect our behavior, it's then on us to identify them and then work to mitigate them. Dr. Alissa Thomas: Thank you. How do racial biases in patients and physicians influence treatment decisions or ultimately, how does this affect patient outcomes in Oncology? Dr. Lauren Hamel: You know, I think the direct relationship between certain biases and outcomes is still kind of being uncovered and investigated. But there are some interesting patterns that have been uncovered in data, specifically in the Oncology context too, because as you can imagine, a variety of professional organizations and groups examine the influence of bias. But just within Oncology, we see physicians who have higher levels of implicit bias who tend to see their patients who are black as less trustworthy, less educated, and less adherent to treatment recommendations. We also know that higher levels of implicit bias may be associated with less aggressive treatment programs recommended for black patients. We see some associations between levels of implicit bias and verbal dominance. But what was I think, especially interesting, is that we also see patterns of kind of perceptions from the patients that these physicians are communicating with. So, we see some manifestations in behavior, but we also see patients kind of "picking up" on some of these, whether or not they can identify them as bias necessarily. But for example, we see that patients who are seeing a physician with higher levels of implicit bias tend to see their physicians as less patient-centered, and less trustworthy. And I think that's a really important piece to identify because these biases are by definition kind of operating outside of our own consciousness, but they're manifesting themselves in a way that the people that we're communicating with are noticing. Dr. Nimish Mohile: We had a patient a few years ago who had presented to our clinic, who ended up having a diagnosis of primary central nervous system lymphoma, and she was a young black woman, and it took about nine months for her to get that diagnosis. She had gone into multiple emergency rooms, she was only 22, had not had prior interaction with the medical system, but based on some of her socioeconomic demographics, her skin color, she was never given the kinds of testing that any other patient I think should have gotten at that time. That was a real sort of wake-up call for our clinic, because as some of you know, this is a disease that we can really treat, especially in younger patients. So, there's real consequences to these kinds of biases. And some of them are personal, the ways they're ingrained in us, but some of them are built into our systems, and it's based on; what our ERs are designed like, where our hospital systems are, what kind of relationships we have with primary care physicians in different communities, what kind of access some of our patients have to primary care physicians. This patient in particular didn't have great access to primary care, so she didn't have this other team of people to advocate for her and to say, "Hey, you know, this is something really different in this patient, and we need to take this seriously." So, I think it can get complicated as we think about biases in ourselves, in other people, in the whole health system, and then also as we get out of our health system, some of these things are so influenced by what's going on in our communities. Dr. Lauren Hamel: Yeah, I think that's a really important point. At least with my work, I examine kind of at the interpersonal level, but these biases, as Dr. Mohile points out, exist in all levels of our society, and they interact, and they're-- I don't want to say additive, it's probably much more exponential. But yeah, it's a layer, on top of layer, on top of layer problem. Dr. Alissa Thomas: So, Dr. Mohile, you commented earlier that part of it is recognizing these biases in ourselves. Can you discuss how we might approach this with the impact of an anti-racism education program has been in your department and applications for that? Dr. Nimish Mohile: So, we've worked on anti-racism in our department on a couple of levels. One of the main levels is just building awareness for individuals to understand that they have biases, that they have racial biases, and starting to understand why they have those. So, we've gone through exercises like book clubs and talks, for people to really do some of that self-reflective work to understand how they've been conditioned as they grew up. I've personally done that and have found it very revealing and understood some of the biases that I grew up with based on people I was around, and based on my schools, and based on segregation within my school systems. So, I think that that's one piece of it. I think another piece is we don't often get taught about the history of racism in the United States, and how widespread it is. It's a very small part of our curriculums, and I think we have to take it upon ourselves now in our medical systems to go through that education. Education that we probably should have had all through elementary school, high school, college, we have to do that learning now because then we can really start seeing that impact of race on our society. And I think for physicians specifically, what is that impact of racism on patient care in our medical systems and how it's been ingrained in US healthcare. Understanding that we had segregated hospitals right until the 1960s, those are all thin
