Data Source
The Nationwide Readmissions Data (NRD) is a part of the Healthcare Cost
and Utilization Project (HCUP) databases, which has been developed
through a Federal-State-Industry partnership and sponsored by the Agency
for Healthcare Research and Quality (AHRQ). HCUP databases include the
largest collection of de-identified longitudinal hospital care data in
the United States, with safeguards to protect the privacy of individual
patients, physicians, and hospitals. The NRD contains more than a
hundred clinical and nonclinical variables for each hospital stay
including a verified patient linkage number for linking hospital visits
for the same patient across hospitals, International Classification of
Diseases, Tenth Revision, Clinical Modification/Procedure Coding System
(ICD-10-CM/PCS) for principal and secondary procedures and diagnoses
(including comorbidities and complications), age, gender, length of stay
(LOS), and others.[16,17]
