Summary of Discontinued Surveys and Data Collection Systems

SOA was conducted as a supplement to the 1984 National Health Interview Survey. The study included participants aged 55 years and over to characterize the health and social status of the group, and to provide information on how psychosocial and environmental factors interact with health factors to influence the aging population.

SOA served as the baseline for LSOA, a prospective study with a nationally representative sample of persons aged 70 years and over at the time of their 1984 SOA interview. LSOA followed the cohort of older persons through three follow-up interviews conducted in 1986, 1988, and 1990.

SOA II replicated the first SOA roughly 10 years later with a new cohort of persons aged 70 years and over to determine whether there were changes in the level of disability among older persons between 1984 and the mid-1990s.

LSOA II, a prospective study with a nationally representative sample from SOA II, followed a cohort of older persons through two follow-up interviews, conducted in 1997–1998 and 1999–2000, to determine whether there had been changes in disability or factors associated with disability among older persons between the 1980s and 1990s.

NHIS–D was conducted to meet the overlapping data needs of four Department of Health and Human Services offices to provide a useful set of measures while maintaining a balance between the social, administrative, and medical considerations involved in disability measurement. NHIS–D was not limited to one definition of disability; therefore, it allowed analysts from varying programs to combine data items in different ways to meet specific agency or program needs.

HHANES was a one-time health examination survey focused on three major subgroups of the Hispanic population—Mexican Americans in the southwest; Cubans in Miami (Dade County), Florida; and Puerto Ricans in the New York City area. Hispanic persons were included in past health and nutrition examination surveys, but not in high enough numbers to produce estimates of the health of Hispanic persons in general, or specific data for subgroups.

NHEFS was designed to investigate the relationship between clinical, nutritional, and behavioral factors assessed in the first National Health and Nutrition Examination Survey (1971–1975), and later morbidity, mortality, and hospital use, as well as changes in risk factors, functional limitations, and institutionalization.

NNYFS was conducted to collect data on physical activity and fitness levels in U.S. children aged 3–15 years. The survey provided an evaluation of their health and fitness levels through interviews and fitness tests.

NHDS was a national probability survey designed to meet the need for information on characteristics of inpatients discharged from nonfederal short-stay hospitals in the United States.

NNHS was a continuing series of national sample surveys of nursing homes, their residents, and staff. Although each of these surveys emphasized different topics, they all provided some common basic information about nursing homes, their residents, and staff. All nursing homes included in this survey had at least three beds and were either certified (by Medicare or Medicaid) or had a state license to operate as a nursing home.

NHPI was a comprehensive national listing of health care facilities, including nursing homes, home health agencies, hospices, and licensed residential care facilities. Data collected included information on the services, location, staff, and other characteristics of the facilities; this data provide a sampling frame of facilities for other health care provider surveys.

NHHCS is a continuing series of nationally representative sample surveys of U.S. home health and hospice agencies. It was designed to provide descriptive information on home health and hospice agencies, their staff members, services, and patients.

NSAS provided the only national data on ambulatory surgical care in hospital-based and freestanding ambulatory surgery centers. Ambulatory surgery centers are now included in the National Hospital Ambulatory Medical Care Survey.

NNAS was the first national study of nursing assistants working in nursing facilities in the United States. The survey looked at the important role of nursing assistance in providing long-term care services for the growing elderly and chronically ill populations, and provided new information needed to recruit, retain, and expand the paraprofessional long-term care workforce.

NHHAS was the first national probability survey of home health aides, designed to provide national estimates of home health aides employed by agencies that provide home health or hospice care. The survey was conducted as a supplement to the 2007 National Home and Hospice Care Survey.

NSRCF was a first-time national data collection effort to gather information about the characteristics of residential care facilities, including assisted living residences, board and care homes, congregate care, enriched housing programs, homes for the aged, personal care homes, and shared housing establishments.

National Ambulatory Medical Care Survey (NAMCS) Asthma Supplement, 2012

The NAMCS Asthma Supplement was conducted to collect data from physician offices and community health centers about the clinical decisions made about asthma in everyday practice. icon

National Ambulatory Medical Care Survey (NAMCS) Physician Workflow Survey, 2011–2013

The NAMCS Physician Workflow Survey was conducted as an NAMCS supplement and represents a 3-year initiative to survey office-based physicians about their experience in, and perceptions of adopting and using electronic health record systems. icon

The NAMCS Primary Care Supplement was conducted to document clinical guidelines and protocols used when treating patients for high blood pressure, high cholesterol, or diabetes.

The NAMCS Supplement on Culturally and Linguistically Appropriate Services was a survey of office-based physicians designed to examine cultural and linguistic competency, provision, training, and awareness among office-based physicians to provide national and regional estimates.

NMIHS collected data needed by federal, state, and private researchers to study factors related to poor pregnancy outcomes, including low birthweight, stillbirth, infant illness, and infant death. The survey expanded on information available from birth, fetal death, and infant death vital records and was the first national survey that included data on the three pregnancy outcomes simultaneously. A longitudinal follow-up study was conducted in 1991 to obtain additional information about respondents from the 1988 survey.

NMFS was conducted using a sample of U.S. residents who died in a given year to supplement the death certificate with information from a person familiar with the decedent’s life history. The information, sometimes enhanced by administrative records, provided a unique opportunity to study the etiology of disease, demographic trends in mortality, and other health issues.

National Employer Health Insurance Survey (NEHIS), 1994

NEHIS was the first federally sponsored survey designed to produce state estimates of employer-sponsored health insurance. The objective was to measure state and national levels of health insurance spending by employers, to provide baseline data at the state and national levels for monitoring trends in the employment-based health insurance system, and to provide data for prospective policy analysis of the effects of health care reform. icon

Conducted in 2014, NHPI NHIS was patterned after NHIS and surveyed about 3,000 households with one or more NHPI residents. The survey provided an opportunity to collect information on health status and conditions, disability, access to and use of health services, health insurance coverage, immunizations, risk factors, and health-related behaviors from a large NHPI sample in all 50 states.

NSECH focused on the delivery of pediatric care to families with children under age 3 years and the promotion of young children’s health by families in their homes.

NS–CSHCN assessed the prevalence and impact of special health care needs among children in the United States and evaluated change over time. The survey explored the extent to which children with special health care needs had medical homes, adequate health insurance, access to needed services, and adequate care coordination.

NAS examined the health and socioeconomic, behavioral, and environmental predictors that relate to better control of asthma. The study explored the care and health care expenditures of persons with asthma.

NSCH examined the physical and emotional health of children aged 0–17 years. Special emphasis was placed on factors that may relate to the wellbeing of children, including medical homes, family interactions, parental health, school and after-school experiences, and safe neighborhoods.

SATH was a nationwide survey looking at the health of young people who were aged 19–23 years in 2007 and whose parents were originally interviewed in 2001 in a previous SLAITS health survey when the subjects were aged 14–17. The goal of the follow-up survey was to examine their current health care needs and their transition from pediatric health care providers to adult health care providers.

NSAP provided nationally representative estimates on the characteristics, pre-adoption experiences, and post-adoption support experiences of families of adopted children aged 0–17 years. These children were identified in other SLAITS surveys as being adopted through the U.S. foster care system, domestic private adoption agencies, or international adoption.

NSAP–SN provided nationally representative estimates on the characteristics, pre-adoption experiences, and post-adoption support experiences of families of adopted children with special health care needs aged 0–15 years.

The Pathways Survey was a nationally representative survey about children with special health care needs aged 6–17 years who were ever diagnosed with autism spectrum disorder, intellectual disability, or developmental delay. Parents or guardians were asked about the emergence of symptoms, the context of the original diagnoses, the providers who made the diagnoses, the child’s current diagnostic status, the types of clinical treatments or interventions and educational services used to address the developmental problems, and other parental concerns or perspectives.

NSCNC provided nationally representative estimates on the characteristics, living arrangements, and service accessibility of noninstitutionalized children who were living apart from their parents (in foster care, grandparent care, or other nonparental care) and who were aged 0–16 years in 2011–2012.

NS–DATA was a survey about children aged 2–15 years old in 2011–2012 who had ever been diagnosed with attention-deficit/hyperactivity disorder or Tourette syndrome. Parents and guardians were asked about the emergence of symptoms, the context of the original diagnosis, the providers who made the diagnoses, the children’s current diagnostic status, current symptoms and level of impairment, and the types of clinical treatments, interventions, and educational services received.
