  1. What are the characteristics of joint replacement patients (DRGs 209 & 210) served in IRFs and SNFs? How are they similar or different?
  2. How are the interventions and processes of care for joint replacement patients different in IRFs and SNFs?
  3. What specific interventions or combinations of interventions in IRFs and SNFs make the biggest difference in outcomes for joint replacement patients taking into account patient differences?
  4. Which joint replacement patients do better in an IRF and which do better in a SNF?
  5. What is the relative cost-effectiveness of IRF and SNF care for joint replacement patients?
  6. Are comorbidities among joint replacement patients an adequate indicator of additional medical need during the rehabilitation process? Can a severity-of-illness measure serve as a better indicator of medical need? Are patients with greater medical needs served better in an IRF or a SNF?
  7. Can we design a more efficient course of rehabilitation interventions for joint replacement patients in IRFs and SNFs to reduce the length of stay and costs?

  Show Detailed Description


Ages Eligible for Study:   21 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Are 21 years of age or older,
  • Received a hip or knee replacement of any type for any reason, and
  • Admitted from any source.

To be included in the study’s database, the above enrollment criteria need to be met. In addition, patients also must:

  • Have a minimum rehabilitation length of stay (LOS) of 3 days, and
  • Have complete admission and discharge FIM data.

Exclusion Criteria:

  • Joint replacements such as shoulder and ankle replacements since the rehabilitation for these patients is quite different. For most study patients, the joint replacement will be their first, but with the aging of the population, revisions are becoming more common. According to the MedPAC-RAND report, 4.8% of IRF and 6.3% of SNF joint replacement patients had a revision.
