Pricing the Bundle: Regression<br />

Methodology<br />

Dobson DaVanzo performed a series of multivariate regression<br />

analyses to simulate a nationwide bundled payment system<br />

• Dependent Variable: Current Medicare allowed payment per<br />

episode (including patient copayments, Indirect Medical Education<br />

[IME], disproportionate share hospital [DSH] payments, and<br />

capital)<br />

• Independent Variables: Beneficiary, facility, and episode<br />

characteristics (e.g. age, sex, chronic conditions, functional ability,<br />

IME, first post-acute care setting after hospital discharge)<br />

Simulated bundled payments are the “predicted” Medicare allowed<br />

payments under the various models for each patient episode<br />

Dobson/DaVanzo then applied an outlier model comparable to the<br />

Inpatient Prospective Payment System (IPPS) outlier policy<br />
