I like your point about the fact that complex health conditions that require more coordination and an interdisciplinary approach are likely to have larger health disparities. And while I definitely agree with you about the issue of financial coverage, as we discussed in class this is usually considered distinct from the issue of health care disparities.
With respect to influences on the individual physician level, I think communication is key, but the question for this class is how that might be related to disparities specifically. Are patients of color/low SES patients likely to experience poor quality communication? If so, why? And does this matter only because it is connected to a health outcome, or is it, as Berwick argues in the Triple Aim, also because patient experience is an end in and of itself that we should consider. Therefore, disparities in communication are a health care disparity by definition, regardless if they are linked to worse clinical outcomes, because they reflect disparities in the quality of care.
