🚨New paper in @jama.com IM 🚨 Medicare Advantage (MA) costs ~20% more, but offers financial protections that Original Medicare doesn’t. In diabetes, we don’t find evidence that this translates to better outcomes. This raises the ? of what the extra $ is buying jamanetwork.com/journals/jam...

If the relevant question is how to obtain the greatest health value for the money spent, a cost-effectiveness analysis or cost-benefit analysis is more suitable than return on investment.

For the times when considering diff-in-diff (and event study, comparative interrupted time series, etc), this paper does a nice job of establishing what the “maximal” DAG that would support parallel trends would be, to then think if it fits your specific case: onlinelibrary.wiley.com/doi/abs/10.1...

Using Causal Diagrams to Assess Parallel Trends in Difference‐in‐Differences Studies
Difference-in-differences (DID) is popular because it can allow for unmeasured confounding when the key assumption of parallel trends holds. However, there exists little guidance on how to decide a p...

Then for remaining arrows, think about whether I can block flow of information through that path by conditioning, weighting, matching, or differencing.
100
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
Should also say: I like to start with all possible arrows/edges in place, and then think of each one I’d like to remove as making an “exclusion restriction” assumption, and so think about whether that assumption is justifiable or not.

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
So you’ll end up in one of a few possible situations. And then can sort out whether the analytic approach you want to use would work in that situation, and whether you can make a case that you are in that situation vs. one of the other options.

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
I think starting with a two-period “building block” helps. Outcome Y0 in pre-period and Y1 on post-period, treatment A0 and A1, time fixed confounder, time varying confounders L0 and L1 +/- mediators if relevant. Ultimately there aren’t that many possible configurations
100
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
And that way you’ve kind of laid out what your assumptions are so that you and others can think thru whether that is actually the case empirically or not. So overall I just kind of think about it as a tool to get clear on what assumptions I’m making for identification.

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
Basically I think you want something along the lines of “here’s what I think is going on, if that’s correct, my method will identify a causal effect (or I need to use a particular method because I’m worried about some specific causal structure)”.
110
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
But I don’t really think of DAGs as really being “for” a detailed picture of what causes a specific phenomenon. Instead I think you want big picture ideas like where so time fixed and time varying confounders fit in? Where do mediators fit in?
110
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/06/2026
Not sure if this is one of the issues you’re running into but the key thing for me is to think about data structure overall and “groups” of variables rather than every specific variable. Sometimes people try to put every causal factor they can think of on the DAG.

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
But I think current practitioners keep bumping up against the limitations of the method so I advocate a different approach (building on what we know about the level and distribution of harms) that I think is more useful for improving health equity. Happy to send you a copy of the book if you’d like!

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
Definitely agree. Some of this is “inside baseball” between Atheen and I because he helped me with my book where I talk about a lot of these issues (esp in Chapter 2). Certainly the disparitarian approach has been useful in calling attention to problems

In other words, I think comparing observed health outcomes Y between group A and group B creates problems. Would be better to compare counterfactual health outcomes YA0 (outcomes for group A under unjust exposure/policy regime) and YA1 (outcomes for group A under more just exposure/policy regime).

Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
Focusing on injustices that harm health as the way to think about health inequity works better than measuring health (in)equity as differences/inequalities between groups, IMO.
110
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
The relates back to the idea that the way you measure health equity is to compare health outcomes in a less well off (along some dimension) group to a more well off group. This tells you whether there are ‘inequalities in health’. But I think the approach of comparing two groups doesnt work well.
110
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
I don’t think this really gets at the concern I was trying to raise (not that clearly). The part that I think goes astray is their definition of health equity “We use the term health equity to refer to the absence of inequalities in health that are preventable.”
210
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
Would be a major advance, IMO, to think about health inequity as injustice that harms health, and make counterfactual comparisons (eg, health outcome for focal group under one policy regime vs another). A lot of problems in the field stem from using a less useful conception of health equity.
131
Seth A. Berkowitz @sethaberkowitz.bsky.social · 04/02/2026
Certainly agree with their points about the need for conceptual clarity and methodological rigor but the way they are thinking of health equity still seems based in a “disparitarian” idea that the way to think about health equity is as differences in health outcomes (or not) between groups.

3) high U.S. healthcare spending is mostly driven by high prices, which are in turn the result of our private, multi-payer approach to healthcare finance that precludes the monopsony power needed to control prices, and 4) how we can get better even, or perhaps especially, in the current moment.

In more detail: I discuss 1) why the problems are less interrelated than they are often presented to be, 2) that the roots of poor population health lie in inequitable social policy, rather than healthcare
