National Readmission Database (NRD)

External readmission rate benchmarks are built using the 2019 National Readmission Database. There are 4 All Payer peer groups for utilizing the NRD data:

  • NRD Nationwide (All Payer)
  • NRD – Bedsize – Small (All Payer)
  • NRD – Bedsize – Medium (All Payer)
  • NRD – Bedsize – Large (All Payer)

NOTE: The Bedsize assignments are specified within the NRD dataset and not determined by Clinical Analytics. For more information, see https://www.hcup-us.ahrq.gov/db/vars/hosp_bedsize/nrdnote.jsp.

DRG-level external benchmarks for readmission rates are available for the following measures

  • 3 Day Readmission Rate Forward
  • 7 Day Readmission Rate Forward
  • 10 Day Readmission Rate Forward
  • 14 Day Readmission Rate Forward
  • 30 Day Readmission Rate Forward
  • 1 to 30 Day Readmission Rate Forward
  • 90 Day Readmission Rate Forward
  • 180 Day Readmission Rate Forward

Due to the intent of benchmarks, readmission measure definitions, and the nature of the NRD data, external benchmarks are NOT available for any of the same-day, same-hospital or backward readmission rate measures. There are also no benchmarks for the 1-year readmission rate measures, as the NRD includes only one year of data and encounters are not linkable between years.

Facility-level external benchmarks for readmission rates are available for the following measures

  • CMS 30-Day Hospital-Wide Readmissions (Benchmarks are facility-level)
    • 30 Day All Cause Readmission Rate - Cardio-Respiratory Cohort
    • 30 Day All Cause Readmission Rate - Cardiovascular Cohort
    • 30 Day All Cause Readmission Rate - Medical Cohort
    • 30 Day All Cause Readmission Rate - Neurology Cohort
    • 30 Day All Cause Readmission Rate - Surgical Cohort
    • 30 Day All Cause Readmission Rate - Roll Up All Cohorts
  • CMS 30-Day Procedure-Specific Readmissions
    • 30 Day Readmission Rate - CABG Cohort
    • 30 Day Readmission Rate - THA/TKA Cohort
  • CMS 30-Day Condition-Specific Readmission
    • 30 Day Readmission Rate - AMI Cohort
    • 30 Day Readmission Rate - COPD Cohort
    • 30 Day Readmission Rate - Heart Failure Cohort
    • 30 Day Readmission Rate - Pneumonia Cohort
    • 30 Day Readmission Rate - Stroke Cohort

From AHRQ's HCUP NRD Website

The NRD is drawn from the HCUP State Inpatient Databases (SID) and can be used to create estimates of national readmission rates for all payers and the uninsured. The 2019 NRD was constructed from 27 States with reliable, verified patient linkage numbers in the SID that could be used to track the patient across hospitals within a State, while adhering to strict privacy guidelines.

Key features of the 2019 NRD include:

  • A large sample size, which provides sufficient data for analysis across hospital types and the study of readmissions for relatively uncommon disorders and procedures.
  • Discharge data from 27 geographically dispersed States, accounting for 57.8 percent of the total U.S. resident population and 56.6 percent of all U.S. hospitalizations.
  • Designed to be flexible to various types of analyses of readmissions in the United States for all types of payers and the uninsured.
  • Criteria to determine the relationship between multiple hospital admissions for an individual patient in a calendar year is left to the analyst using the NRD.
  • Outcomes of interest include national readmission rates, reasons for returning to the hospital for care, and the hospital costs for discharges with and without readmissions.
  • The NRD is designed to support national readmission analyses and cannot be used for regional-, state-, or hospital-specific analyses.
