Excited to share our latest paper on bariatric surgery options, now out in @AnnalsofSurgery.

Sleeve gastrectomy is now the most popular bariatric operation, but RCTs of sleeve vs bypass are too small to tell us if sleeve has higher rates of rare complications (e.g. revisions). Observational studies--on the other hand--are always subject to confounding. Healthier patients with lower rates of reflux are more likely to get a sleeve, so if bypass looks worse in observational studies it could be due to baseline differences.

THREAD:
Our study on Medicare readmissions penalties for surgical patients is now out @Health_Affairs
.healthaffairs.org/doi/full/10.13…

We found that the pace of readmissions reductions in joint replacement *decreased* after targeted penalties were announced. Sound strange? Read on. Medicare started penalizing hospitals with high readmissions rates for 3 medical conditions way back in 2010. In 2013, they added hip and knee replacement patients to this program. And they have continued adding more conditions since then.
