Patient Assessments

Overview

Patient Assessments are standardized tools used to determine a patient’s health and functional status and care needs. The information collected is also used for monitoring and improving quality of care and in determining Medicare and Medicaid reimbursement rates. Data collected during the assessments include patient-level socio-demographic, environmental, health and functional status measures.

The Minimum Data Set (MDS) captures information on all residents of Medicare or Medicaid certified long term care facilities. Visit the CMS “Nursing Home Quality Initiative” page for information about MDS and quality measures in long term care facilities.

The Outcome and Assessment Information Set (OASIS) captures information on Medicare and Medicaid patients receiving care from Medicare certified home health agencies. Visit CMS’s “Home Health Quality Initiative” page for information about OASIS and quality measures in home health agencies.

Patient Assessment Data in the VA/CMS Data Repository

The VA/CMS Data Repository contains two Patient Assessment datasets:

  • Minimum Data Set (MDS)
  • Outcome and Assessment Information Set (OASIS)

The VA/CMS Data Repository includes Patient Assessment data for Veterans and non-Veterans.

Visit the "Patient Assessment Data" page for more information on the datasets including descriptions, availability, and unique identifiers included in the data.

Note: The MDS information presented on this page refers to MDS data collected at Medicare or Medicaid certified long-term care facilities. VIReC's "RAI-MDS" page provides information on MDS data collected at VA community living centers (also known as VA nursing homes).

Access

Research access to Patient Assessment data in the VA/CMS Data Repository data is granted through VIReC. Visit the "Pre-Request Consultation" and "Standard Requests" pages for information about requesting these data.
