To me, the advantage of causal inference methods lies in the explicit formulation of what one aims the estimate and the assumptions made. While you cannot prove causality, you can agree or disagree with assumptions and you can do sensitivity analyses (triangulation)

Introp systemic heparin when creating radiocephalic #AVF:
- decrease ⬇️ in thrombosis
- no change ❌ in bleeding

Do you give heparin when creating a #fistula? #medsky #vascsky #hemodialysis

Evaluating the effectiveness of systemic heparin during arteriovenous fistula creation by emulating a target trial Abstract. Most of the 800 000 people living with end-stage kidney disease in the United States rely on a functioning vascular access to provide life-sustai

Alberto Brandolini presents a slide with the text "The amount of energy necessary to refute bullshit is an order of magnitude bigger than to produce it"

It's always a good time to remember Brandolini's principle

Great tool to help migrate from the bird app to bluesky - use early and often before it gets blocked!

At BWH we do trough anti-Xa monitoring selectively in high bleeding risk patients and patients with suspected altered kinetics (eg renal dz), generally do not routinely monitor for ppx dosing for the reasons you cited

Welcome to a few new vascular surgeons to Bluesky 😁

Here’s a starter pack just for you!

How many studies in vascular surgery use NASA data?! Excellent work by @elizabethfyates uncovering the relationship between hot weather and outcomes after carotid surgery at #ASC2023 @AcademicSurgery @LouisLNguyen @CSPH_BWH @BrighamVascular

Star medical student Ascharya Balaji presenting her work at #ASC2023 describing the challenges of identifying peripheral artery disease in healthcare databases - major implications for the epidemiology of PAD! @AcademicSurgery @Jacobs_Med_UB @CSPH_BWH @BrighamVascular

Bias / Variance tradeoff

Excited to get started learning from the masters of #causalinference at the @CAUSALab seminars - @_MiguelHernan knows how to get my attention, introducing counterfactuals with The Matrix

Moonlighting tonight at the Brigham and Women’s HAWKner hospital and met a local eating their dinner @FaulknerHosp

I know I’m getting older because now @NPR plays music I listened to in high school as transition filler

Always crushing it, @KatherineHeMD delivering a great talk AND poster at @MaChapterACS on efforts to combat antibiotic resistance 🦠worsened by unnecessary periop abx usage in kids @BrighamSurgery @CSPH_BWH @BostonChildrens @ShawnRangelMD

THE Brigham looking very New England today - fortunate to be here @BrighamWomens @BrighamSurgery @MassGenBrigham

The @BrighamVascular experience with Snuffbox AVFs: 1-yr 2* patency 92%, reintervention common. 87% of pre-ESRD pts used AVF for incident HD - not catheter. Snuffbox is distal-most access, in line with @VascularSVS guidance. @CKeithOzaki @BrighamSurgery

Looking forward to be working with @CSPH_BWH as I start my research years! The best part of my new work from home setup lurks beneath my desk. I think his hopes to apply for a fellowship next year are a little far-fetched 🙃

Textbook signed by the editor! Such a cool gift from @gmdoherty to all of the surgical residents @BrighamSurgery

A little light reading (featuring Ollie) thanks to an educational grant from the Wyett family @BWHSurgery @dougsmink @jdimick1 @gru6n @HPB_Txp_Surg @LillianKao1 @kmattox1

Team rounds at the Faulkner, in the best workroom of the residency! Dr. Harris’ footwear firmly rooting us in New England @DaveH06 @BWHSurgery @FaulknerHosp

Good times at the @BWH_STRATUS “innovations in chest wall surgery” rib plating workshop, @BWHSurgery GSurg residents representing! Is this the future of flail chest management? #TraumaSurg #ACSCC18

Thanks @becca_scully for setting up the robotic surgery lab today! 🤖@BWHSurgery @MehidaRojas @jcprad11 @KatherineHeMD

Happy 4th! Everyone be careful with those fireworks, or you might end up on the Trauma/Burn Surgery service with us taking care of you 😅 @paige_newell47 #cushingtrauma @BWHSurgery

Thanks @dougsmink for the time and advice today! (We need it 😅) @BWHSurgery @EvaRouanet @Christine_Wu18 @paige_newell47 @KatherineHe2018
