What Does NIS Stand For?
NIS stands for National Inpatient Sample
The National Inpatient Sample (NIS) is a key resource in healthcare research that provides comprehensive data on inpatient admissions across the United States. As part of the Healthcare Cost and Utilization Project (HCUP), NIS aggregates information from a large, diverse set of hospitals, making it an essential tool for analyzing trends in hospitalization, patient demographics, clinical outcomes, and healthcare resource utilization. Researchers and policymakers utilize NIS data to inform evidence-based decision-making and improve patient care across various settings.
