Eligibility Criteria
Inclusion Criteria
- Patients must demonstrate one-year mortality of at least 30 percent (score > 6) according to the Gagne Index, a validated instrument used to measure all cause one-year mortality in community-dwelling older adults, calculated based on their prior 12 months before the index ED visit of Medicare claims.
Exclusion Criteria
- ED patients transferred from a nursing home on the index ED visit will be excluded since prediction of mortality and disposition of such patients differs from community-dwelling adults.
- Patients currently receiving hospice at the time of the index ED visit will also be excluded since they have already received services.
