Overview

The National Hospital Care Survey (NHCS) collects data on patient care in hospital-based settings to describe patterns of health care delivery and use in the United States. Hospital-based settings include inpatient departments, emergency departments, and outpatient departments.

The National Hospital Care Survey is conducted by the National Center for Health Statistics.

NHCS goals

  • Provide nationally representative, accurate, and reliable health care data for hospital-based settings
  • Answer questions about healthcare quality, use of healthcare resources, and the differences in healthcare services that some people and groups experience
  • Address acute and chronic illnesses and respond to public health emergencies
  • Monitor national trends in substance use-related emergency department visits, including opioid visits
  • Provide data that bring together information about contacts between patients and providers across hospital units
  • Link data from hospital-based settings with other data sources such as the National Death Index
  • Contribute to a stronger public health system that can address current and future public health threats

What's collected

NHCS collects data on patient care and resource use in hospital-based settings. Participating hospitals electronically submit inpatient discharge and emergency department visit data. Hospitals also provide, summary on patient visits for the calendar year through an additional, supplemental interview.

Data and documentation

The National Center for Health Statistics publishes reports and maintains dashboards featuring NHCS data. In producing these resources, NHCS staff prioritizes protecting the privacy of participating hospitals and their patients.

Data files

The 2020 NHCS public use data files are available to download in multiple formats. All potentially identifiable information has been removed to ensure the confidentiality of respondents and patients.

Restricted data files are available through the National Center for Health Statistics Research Data Center (RDC) for a fee. To access restricted NHCS data, researchers must submit requests in the Standard Application Process portal. The RDC provides instructions for preparing and submitting an application to access restricted data.

NHCS data also has been linked with data from other sources. This provides more robust datasets that can be used to analyze complex relationships between data from different sources. These linked datasets are available in the RDC.

Find data documentation for these datasets at Questionnaires, Data Sets, and Documentation.
