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]
