The 2004 National Nursing Home Survey (NNHS), conducted between August and December of 2004, was reintroduced into the field after a five-year break, during which time the survey was redesigned and expanded to collect many new data items. All nursing homes that participated in the NNHS had at least three beds and were either certified (by Medicare or Medicaid) or had a state license to operate as a nursing home. The redesigned survey was administered using a computer-assisted personal interviewing (CAPI) system and included a supplemental survey of nursing assistants employed by nursing homes, the National Nursing Assistant Survey (NNAS), which was sponsored by the Office of the Assistant Secretary for Planning and Evaluation (APSE).

The National Nursing Home Survey provides information on nursing homes from two perspectives-that of the provider of services and that of the recipient of care. Data about the facilities include characteristics such as size, ownership, Medicare/Medicaid certification, services provided and specialty programs offered, and charges. For recipients, data were obtained on demographic characteristics, health status and medications taken, services received, and sources of payment.

Data for the survey were obtained through personal interviews with facility administrators and designated staff who used administrative records to answer questions about the facilities, staff, services and programs, and medical records to answer questions about the residents.

The total number of nursing home facilities that participated in NNHS is 1,174 and the total number of nursing assistants that participated in the National Nursing Assistant Survey is 3,017.

The Research and Development Survey (RANDS) is a series of cross-sectional
surveys from probability-sampled commercial survey panels which began in 2015.
RANDS 2 was administered by Gallup using the Gallup Panel in the spring of 2016
and contains existing questions from the National Health Interview Survey (NHIS)
as well as embedded probe questions for cognitive evaluations.

The Research and Development Survey (RANDS) is a series of cross-sectional surveys from probability-sampled commercial survey panels. As part of a special iteration of RANDS that focuses on COVID-19, RANDS during COVID-19 Round 1 is the first round of a three-round survey. The probability sample of RANDS during COVID-19 Round 1 was recruited using NORC at the University of Chicago (NORC)'s AmeriSpeak Panel, and the survey was administered by NORC from June 9, 2020 to July 6, 2020. The RANDS during COVID-19 Round 1 Probability Sample has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.

The National Hospital Care Survey (NHCS) is designed to provide accurate and reliable health care statistics that answer key questions of interest to health care and public health professionals, researchers, and health care policy makers. This includes tracking the latest trends affecting hospitals and health care organizations and factors that influence the use of health care resources, the quality of health care, and disparities in health care services provided to population subgroups in the United States.
NHCS collects data on patient care in hospital-based settings to describe patterns of health care delivery and utilization in the United States. Settings include inpatient, emergency (EDs), and outpatient departments (OPDs). The survey will provide hospital utilization statistics for the Nation. In addition, NHCS will also be able to monitor national trends in substance use-related ED visits including opioid visits.

The purpose of the National CLAS Physician Survey was to understand the provision of culturally and linguistically appropriate services among office-based physicians. The National CLAS Physician Survey was a supplement to the National Ambulatory Medical Care Survey (NAMCS), which is a national probability sample survey of visits to office-based physicians. NAMCS is a component of the National Health Care Surveys that measured health care utilization across a variety of health care providers’ settings. NAMCS and the National CLAS Physician Survey were conducted by the National Center for Health Statistics (NCHS). The National CLAS Physician Survey public use file includes data from office-based physicians. No patient level data were collected. This documentation describes the public use micro-data file produced from data collected in the National CLAS Physician Survey.

The Research and Development Survey (RANDS) is a series of cross-sectional surveys from probability-sampled commercial survey panels. As part of a special iteration of RANDS that focuses on COVID-19, RANDS during COVID-19 Round 3 is the third round of a three-round survey. The sampled participants of RANDS during COVID-19 Round 3 were recruited using NORC at the University of Chicago (NORC)’s AmeriSpeak Panel, and the survey was administered by NORC from May 17, 2021 to June 30, 2021. RANDS during COVID-19 Round 3 has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.

This dataset includes all infant deaths that were linked to their corresponding birth certificate and includes all items released in the public-use file. Additional information in this file includes state and county of residence and exact dates of birth and death (which includes day of month, month, and year).

The Research and Development Survey (RANDS) is a series of cross-sectional surveys using probability-sampled commercial survey panels. The sixth round of RANDS (RANDS 6) was administered by NORC at the University of Chicago using the AmeriSpeak Panel from August 10, 2022 to August 29, 2022. RANDS 6 contained the embedded probe questions and experiments as in previous rounds of RANDS. It also explored different administrations of questions asked on the National Survey of Family Growth (NSFG) through split-sample experiments. RANDS 6 has a known survey sampling design and can be used to produce nationally and sub-nationally representative estimates.

NCHS has linked data from various surveys with 1999-2013 Medicare program enrollment and health care utilization and expenditure data from the Centers for Medicare & Medicaid Services (CMS). Linkage of the NCHS survey participants with the CMS Medicare data provides the opportunity to study changes in health status, health care utilization and costs, and prescription drug use among Medicare enrollees. Medicare is the federal health insurance program for people who are 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease.
