Thanks Emily - great thorough responses. The only addition to your discussion of SES is to consider it as an effect modifier, as we discussed in the lecture. I definitely agree your multilevel analysis of opiod use would be fascinating, and also think Amy's point about the change over time would be interesting in the context of policy change. I am interested in how you are thinking about the disparities lens specifically in this area - is it about access to appropriate palliative care and how that varies by sociodemographic characteristics? Are you looking at issues of diversion?
