public use data set is now available for downloading from our website. The revised public use file documentation is also available. We advise anyone who has used the earlier NSAS data set (released in October 2008) to re-run all analyses using the revised data set before reporting or publishing any 2006 NSAS data. The National Health Statistics Report Number 11, entitled "Ambulatory Surgery in the United States, 2006," [PDF - 468 KB]) has been revised and is now available. The reasons for the revision of the NSAS data set, which affected some of the procedure estimates, are discussed at the beginning of the public use file documentation and in the report. The report also explains that some other estimates of standard errors were printed incorrectly in the original report and these have been corrected. Estimates from the original report should not be used.

The National Health Care Surveys are constantly being updated to address the most relevant policy questions today and in the future. Click on a topic below to read more about our innovations in a particular healthcare setting.
Ambulatory and hospital care
- Physician offices
- Emergency and outpatient hospital departments
- Ambulatory surgery
- Inpatient hospital departments
We are pleased to announce that data from the National Survey of Prison Health Care (NSPHC) (2011) are now available for use in the NCHS Research Data Center (RDC). This survey was a joint effort between the National Center for Health Statistics and the Bureau of Justice Statistics to collect information on the provision and delivery of health care in state and federal prisons in the United States. For more information on this data collection, please visit the NSPHC webpage. For more information on how to access these data, please visit the RDC website.
Physician offices (National Ambulatory Medical Care Survey 2008)
- New data supplement
Cervical Cancer Screening Supplement--administered in 2006, 2007, and 2008 to samples of NAMCS primary care providers who screen patients for cervical cancer. The purpose of supplement is to ascertain what approaches physicians are using to screen for cervical cancer and to manage patients with positive test results.
- Sample size expanded
Community Health Centers--in a departure from the traditional NAMCS design where only physicians are sampled, beginning in 2006, the survey includes an additional sample of community health centers, allowing researchers to make estimates for the care they provide. Within community health centers, the NAMCS is sampling mid-level providers, in addition to physicians.
- Supplemental survey
Electronic Medical Records--supplemental survey about electronic medical records (EMRs) will be mailed to 2,000 office-based physicians in 2008 as a supplement to the NAMCS. EMR questions are comparable to those in the primary NAMCS survey, but no patient level data are collected.
Emergency and outpatient hospital departments (National Hospital Ambulatory Medical Care Survey 2008)
New data supplements
Pandemic and Emergency Response Preparedness Supplement, an extension of the bioterrorism supplements fielded in 2003-2004, this hospital questionnaire will examine various dimensions of hospital preparedness: including training of clinicians to treat weaponizable biological agents and exposures to chemicals and radiation, development of emergency response plans, availability of resources needed to treat such exposures such as negative pressure isolation rooms. The supplement has been updated to reflect newer public health priorities, including emergency response to influenza and severe acute respiratory syndrome (SARS).
Cervical Cancer Screening Supplement--administered in 2006, 2007, and 2008 to hospitals with outpatient departments which screen patients for cervical cancer. The survey will allow us to examine practices regarding the provision of human papilloma virus (HPV) tests for approved and non-approved uses, cervical cancer screening methods, use of HPV tests as an adjunct to Pap testing, use of HPV test results for managing patients with abnormal Pap tests, and potential impact of HPV testing on lengthening Pap testing screening intervals. Some questions will allow evaluation of adherence to recent national guidelines about use of HPV testing a) as an adjunct to Pap testing and b) for management of patients with abnormal Pap tests.
Ambulatory surgery (National Survey of Ambulatory Surgery 2006)
In 2006, we went back into the field to collect data from hospital-based and freestanding ambulatory surgery facilities for the first time in 10 years. Our 2006 NSAS survey also collected data on facility characteristics. Data and reports will be available in 2009.
Annual data collection!
Ambulatory surgery centers are an increasingly important source of surgical care in the United States. Historically, NCHS collected data from the only nationally representative sample of ambulatory surgery visits in 1994-1996 and 2006. Because of the need for more frequent collection of these data, hospital-based ambulatory surgery centers became part of the National Hospital Ambulatory Medical Care Survey (NHAMCS) in 2009. Inclusion of both hospital-based and free-standing ambulatory surgery centers is planned as part of NHAMCS in 2010 and annually thereafter.
Hospital inpatient departments (National Hospital Care Survey)
The National Hospital Care Survey (NHCS) is a new survey started in 2011 that integrates inpatient data formerly collected by the National Hospital Discharge Survey (NHDS) with emergency department (ED), outpatient department (OPD), and ambulatory surgery center (ASC) data collected by the National Hospital Ambulatory Medical Care Survey. Currently a sample of 500 non-institutional, non-federal hospitals with six or more beds in the United States is being recruited for this survey. During the first two years of the survey, sampled hospitals will be asked to provide Uniform Bill (UB)-04 administrative claim data for all inpatients, as well as facility-level data through a facility questionnaire. In 2013, in addition to inpatient data, the hospitals will be asked to provide data on the utilization of health care services provided in their EDs, OPDs, and ASCs. Also in 2013, a sample of freestanding ASCs will be recruited. You can learn more about the survey at: /nchs/nhcs.htm.
Residential care facilities (National Survey of Residential Care Facilities)
A new survey of residential care facilities is under construction to be fielded for the first time in 2010.
The National Survey of Residential Care Facilities will be used to address important research and policy questions:
- What are the number and characteristics of residential care facilities? Characteristics include number of units and beds; occupancy rate; ownership (profit/nonprofit, chains/stand-alone small businesses); geography and location (urban/rural); and type of facility (e.g., the extent to which facilities provide private rooms and bathrooms and a high level of services). What are admission and discharge policies? What proportion of facilities serve Medicaid beneficiaries, and if not, why not? Do facilities use restraints? Do facilities use negotiated risk contracts?
- What services and staff are available in residential care facilities? What services do residential care facilities provide and at what level and cost? What services are included in the basic rate? What services are available for additional charges? What skilled services are available and who provides them? Does the facility use or allow outside providers, such as hospice and home health agencies? What is the staff turnover rate? Do facilities that serve residents with a high level of impairment and health needs have more and better trained staff?
- What are the number and characteristics of residents in residential care facilities?
What are residents' sociodemographic characteristics (e.g., age, sex, race, education, ethnic group, family)? What are the residents' health condition and cognitive and functional status? What is the average length of stay in residential care facilities and the reasons for entering and exiting? How do people pay for residential care? What are the charges for care? How do resident characteristics and outcomes vary by type of residential care facility?
Our next surveys are still being planned.
Data are now available from the 2004 surveys. Relative to earlier surveys, the 2004 National Nursing Home Survey has many new features, including:
- Data on medications taken by current nursing home residents.
- Questions on advance directives and end-of-life care.
- Information on the professional background of key nursing home personnel.
- Data on nursing staffing, including turnover information.
The National Nursing Assistant Survey was conducted for the first time in 2004:
- Interviews of nursing assistants were conducted as part of the 2004 NNHS.
- Information on nursing assistants' plans to stay in current positions.
- Questions on job satisfaction, work environment, and more.
The most recent National Home and Hospice Care Survey was conducted from August to December 2007. Data files will be released in 2009 and will have new information on:
- End-of-life care
- Key administrative personnel
- Electronic medical records
Data files will also include a first-time National Home Health Aide Survey:
- Interviews of home health aides conducted as part of the 2007 National Home and Hospice Care Survey.
- Collecting information comparable to that in the 2004 National Nursing Assistant Survey.
