The National Hospital Care Survey provides nationally representative data on inpatient hospital care, as well as care delivered in emergency departments (ED). For more information, please see the site About NHCS and Overview Flyer [PDF – 177 KB].
Objective and timely data are essential to assess the health and well-being of the population and the performance and functioning of the health care system. Your participation in NHCS is important because without your involvement, your hospital and others like yours will not be represented in the national description of care provided by hospitals. Your hospital was randomly chosen to provide representative data not only for your hospital, but also for similar hospitals of the same service type, bed size, and geographic location. For more information about your participation, please see our webpage Why Participate in NHCS.
For the electronic data component, we are asking all participating hospitals to:
- Participate in a one-time eligibility interview to determine your hospital’s eligibility and the eligibility of your hospital’s emergency department (ED).
- Complete an Annual Hospital Interview on hospital characteristics, total admissions, total births, total number of beds, and total ED visits.
- Submit electronic health records (EHR) or Uniform Bill (UB)-04 administrative claims data for all inpatient discharges and ED visits. We will also accept an electronic file in the same format submitted to the state.
You may be asked to participate in voluntary special studies on occasion.
Better Health Care Data: The National Hospital Care Survey (NHCS) has the potential to capture the continuum of patient health care both across and beyond hospital settings. By linking visits across inpatient and outpatient settings as well as with external data sources such as the National Death Index, NHCS can provide better information about resource utilization and post-discharge mortality. Your hospital’s voluntary participation is critical to this data collection effort!
Make a Difference: Your hospital will be part of a health care study that will lay the groundwork for analysis of health care, utilization, and integration of services across a broad spectrum of settings. The important data your hospital provides will inform policies to improve the state of health care in the nation.
Access to the National Health Care Services Registry: The National Health Care Surveys are working together with the Centers for Medicare and Medicaid Services (CMS) Electronic Health Record (EHR) Incentive Programs: Promoting Interoperability (PI) (formerly known as Meaningful Use), and the Merit-based Incentive Payment System (MIPS). Registration is free of charge.
Meaningful Data for Your Hospital: Your hospital data will be collected, analyzed, and shared with you! Health care utilization statistics from your hospital will be returned to you in an easy to read single sheet summary report, containing figures and tables. Your participation is not only useful to the nation, it will be useful to you!
Community Benefit: Non-profit hospitals participating in NHCS may be eligible for a tax exemption. For more information, please visit the community benefit page.
Additional Benefits: In addition to the summary data provided, your hospital will be compensated for set up and for each year of participation. We are here to help! Our survey staff is available to provide technical assistance to facilitate setting up data transmission mechanisms and schedules, as well as to furnish ongoing support.
Your health care facility was randomly chosen to provide representative data not only for your hospital, but also for similar hospitals of the same service type, bed size, and geographic location. Selections were made to obtain enough facilities of different sizes, service types, and geographical locations to ensure that the hospitals in our survey are representative of all hospitals in the United States so that national estimates of hospital care can be produced.
The following information will be collected:
- Hospital-level data – Hospital characteristics (e.g., ownership status, trauma level rating, teaching hospital status, total admissions, and total births) are collected through administration of the Initial Intake Questionnaire and the Annual Hospital Interview.
- Patient data – Patient data (both inpatients and ED patients), are collected electronically in one of three ways: through collection of electronic health records, UB-04 administrative claims, or a copy of the file that is sent to the state health department.
NCHS has contracted with Westat for recruitment and for data collection activities of NHCS. Westat is an agent of NCHS.
Once your hospital decides to participate in the survey, you will be contacted to arrange the following:
- Eligibility Interview: A one-time interview to determine eligibility and obtain general information about your hospital. This may take up to one hour, including answering any questions you may have.
- Annual Hospital Interview: An annual questionnaire conducted either by telephone, email, or web portal to obtain specific information about hospital characteristics, total admissions, total births and total number of beds. This will take up to two hours to complete.
- Electronic Data Submission: The time to set up or complete the submission process will vary by hospital but can take up to four hours.
Not all activities will occur concurrently. Throughout the survey NCHS and its agents will remain respectful of your hospital’s priorities and work closely with you to arrange for work to be completed on a schedule that best accommodates your hospital.
Yes. NCHS is required by law to keep all data regarding patients and hospitals confidential and to use these data only for research and statistical purposes, as stated in Section 308(d) of the Public Health Services Act [42 United States Code 242m (d)] and Section 3572 of the Confidential Information Protection and Statistical Efficiency Act (Pub. L. No. 115-435, 132 Stat. 5529 § 302]. All protected health information will be kept confidential and will be used only by NCHS staff, contractors, and agents—only when required and with necessary controls. CIPSEA also includes provisions for a felony conviction and/or a fine of up to $250,000 if NCHS staff or any NCHS contractor staff violates the confidentiality provisions.
The National Hospital Care Survey has been approved by the NCHS Ethics Review Board (ERB). If you have questions about your rights as a participant in this survey, please call the Research Ethics Review Board at NCHS, toll-free, at 1–800–223–8118. Please leave a brief message with your name and phone number and say that you are calling about Protocol 2021–01.
For more information about your confidentiality, please see our Confidentiality page.
We take your privacy very seriously. The answers you give us are used for statistical research only. This means that your answers will be combined with other people’s answers in a way that protects everyone’s identity. As required by federal law, only those NCHS employees, our specially designated agents (Westat), and our full research partners who must use your personal information for a specific reason will do so. Anyone else will only be allowed to use your data after all information that could identify you has been removed.
Strict laws prevent us from releasing information that could identify you or your family to anyone else without your consent. A number of federal laws require that all information NCHS collects be held in strict confidence: Section 308(d) of the Public Health Services Act [42 United States Code 242m (d)] and Section 3572 of the Confidential Information Protection and Statistical Efficiency Act (Pub. L. No. 115-435, 132 Stat. 5529 § 302], and the Privacy Act of 1974, 5 U.S.C. § 552a.
Any NCHS employee, agent or contractor who willfully discloses ANY identifiable information could get a jail term of up to five years, a fine of up to $250,000, or both.
Yes. NHCS is being conducted under the auspices of CDC/NCHS, a federal statistical agency. Special provisions within HIPAA permit health care facilities to provide data to public health entities such as CDC/NCHS for purposes such as NHCS.
The HIPAA Privacy Rule recognizes 1) the legitimate need for public health authorities and others responsible for ensuring the public’s health and safety to have access to protected health information to conduct their missions, and 2) the importance of public health reporting by covered entities in identifying threats to the public and individuals. The Privacy Rule permits 1) protected health information disclosures without a written patient authorization for specified public health purposes to public health authorities legally authorized to collect and receive the information for such purposes, and 2) disclosures that are required by state and local public health or other laws [HIPAA regulations (45 CFR 164.501)].
Thus, HIPAA permits hospitals such as yours to participate in studies of this nature, such as NHCS, for public health purposes. Because our contractor is serving as authorized agents of NCHS, it is permissible to disclose data to it for the purposes of this project. HIPAA also permits covered entities to obtain the documentation and rely on the approval of one ERB or privacy board. In this case, the hospital may rely on the approval of the NCHS’ ERB.
No. Under the 2018 requirements of the Common Rule ((45 CFR 46.102(l)(2)), the National Hospital Care Survey (NHCS) is now designated as a public health surveillance activity, rather than a research project. In turn, the NCHS Ethics Review Board (ERB) has reviewed and approved the NHCS. Please see the NHCS ERB approval letter [PDF – 54 KB]. If you desire, your hospital’s Institutional Review Board (IRB) may review the project as well. Your IRB can verify that the ERB approval letter we have provided adheres to the requirements of the Privacy Rule, and we can send you a copy of the materials submitted to the ERB.
NHCS data will be used by the U.S. Congress and other public health policy makers, government agencies, academic institutions, professional associations, health services researchers, and the media to describe and understand the changes that occur in health care delivery.
In addition to providing a national description of health care delivery in hospital-based settings, NHCS will allow for the linkage of encounters of care both within the same hospital and with outside data sources such as the National Death Index and Medicare and Medicaid data sets. Linking to other government data will allow for more comprehensive analyses, such as measurement of post-discharge mortality and re-admission rates. Please see our Data Uses page for examples of reports that are produced with NHCS data.
