Gaming the System: LTACHs, Guidelines, and the Evidence Problem in American Medicine

Episode SummaryDr. Anil Makam — hospitalist, health services researcher at UCSF, and faculty at Zuckerberg San Francisco General — joins Drs. Koka and DiGiorgio for a wide-ranging conversation on the hidden mechanics of American healthcare. Makam breaks down long-term acute care hospitals (LTACHs): what they're for, how regional variation and perverse payment incentives have distorted their use, and what the 2016 site-neutral payment reforms actually did to the market. The conversation then shifts to Makam's research on clinical practice guidelines — specifically his 2018 study showing that the majority of ATS recommendations were grounded in low-quality evidence, many carrying strong designations anyway — and what that means for how clinicians should read and apply guidelines at the bedside. The episode closes on the FDA, indication creep, the limits of central planning in quality measurement, and what it actually means to be a good doctor in a system where you can't buy your way to better medicine.Chapter Markers00:00 Introduction — Dr. Anil Makam, UCSF hospitalist and health services researcher02:09 What is an LTACH?
