What’s new?
📍 We combine CDC mortality data with state gun policy scores (2018–2022)
📍 We reveal where and when suicide risks diverge most by sex & policy
🔵 In permissive states, male suicide risk is:
• Higher in YA (15–34)
• Steepest in late life (65+)
• Driven by firearms

🚨 NEW in American Journal of Preventive Medicine with Nate Glasser, Nabil Baker, Harold Pollack, & Elizabeth Tung
We show that permissive state firearm policies amplify sex differences in suicide—especially among young and older men

Unfortunately, one of the many the grants canceled at @Harvard.edu was my T32 in Comparative Effectiveness Research for Suicide Prevention
If you’re coming to #SMDM47 @smdm.bsky.social come see the previously funded great work we are doing related to suicide prevention

Woo 🥳 3rd consecutive year I will be teaching my reproducibility and project management short course at #SMDM annual meeting
ALSO if anyone knows any health/med journals looking to up their code sharing and reproducibility requirements please let me know 🙏

We find that quasi random assignment to a “batcher” relative to a “sequencer” physician has implications for:

Imaging volume 📈

We examine ED physician variation in tendency to batch order diagnostic imaging (the practice of placing multiple imaging test orders at the same time).

Would you rather be seen by an ED physician who orders their tests in a batch or in sequence?

The decision tree model using heterogeneity & ploidy achieved:
✅ High specificity (97%)
✅ Strong PPV (90%)
This helps identify patients unlikely to benefit from single-agent aPD-1 ICB, who might need combo therapies.

Across different cohorts, low ploidy 📉 and high heterogeneity 📈 robustly identify patients with intrinsic resistance to aPD-1 therapy

Findings suggest that physicians who predominantly make use of batching (“batchers”) tend to order more tests, which is associated with longer lengths of stay and increased costs
