To estimate the effect of implementing a tele‐ and a critical care residency training program for advanced practice providers on service utilization and total Medicare episode spending.

Data Sources/Study Settings

Medicare claims data for fee‐for‐service beneficiaries at 12 large, inpatient hospitals in the Atlanta Hospital Referral Region.

Study Design

Difference‐in‐differences design where changes in spending and utilization for Medicare beneficiaries eligible for treatment in participating s was compared to changes in a comparison group of clinically similar beneficiaries treated at similar hospitals’ s in the same hospital referral region.

Extraction Methods

Using Medicare claims data from January 2010 through June 2015, we defined measures of Medicare episode spending during the stay and subsequent 60 days after discharge, and utilization measures within 30 and 60 days after discharge.

Principal Findings

Implementation of the advanced practice provider residency program and tele‐ was associated with a significant reduction in average Medicare spending per episode, primarily driven by reduced readmissions within 60 days and substitution of home health care for institutional postacute care.


Innovations in workforce training and technology specific to the may be useful in addressing the shortage of intensivist physicians, yielding benefits to patients and payers.
