Accessing the National Readmissions Database (NRD)

What is the National Readmission Database?

The National Readmissions Databases (NRD) is a database focused on national hospital readmission trends. The NRD contains patient data on patients regardless of expected payer as well as patients with and without repeat hospital visits in a year.

The NRD does NOT track the same patients year to year. Repeat stays in a calendar year may or not be related. It is up to analysts to determine if a relationship between admissions exists.

Potential Research Uses

The National Readmission Database (NRD) can be used to apply more than 100 clinical and nonclinical variables to your research, including:

  • Verified patient linkage number that identifies discharges belonging to the same individual
  • Timing between admissions for a patient
  • Length of inpatient stay in days
  • Identification of transfers, same-day stays, and combined transfer records

The NRD can be used for research on a variety of topics, including:

  • National rates of readmission by diagnosis, procedure, patient demographics, or expected payer source
  • Costs associated with readmissions
  • Reasons for readmissions
  • Impact of health policy changes
