Boston Rehabilitative Impairment Study of the Elderly (Boston RISE), 2009-2015 (ICPSR 37045)

Released/updated on: 2021-01-28
Geographic coverage: Massachusetts, Boston
Time period: 2009-01-01--2015-01-01
The Boston Rehabilitative Impairment Study of the Elderly (Boston RISE) was a prospective cohort study of older primary care patients, aged 65 years and older, who were at risk for declining mobility and disability at baseline. The study was designed to investigate which combinations of neuromuscular impairments are most responsible for mobility decline and disability over 2 years of follow up. Through additional funding, Boston RISE continued to collect follow up data on the Late Life Function and Disability Instrument (LLFDI) and mobility-related and healthcare utilization outcomes over the phone as part of a 2-year extension. Several ancillary measures were also collected throughout the course of the study.

Geographic coverage: United States, California
Time period: 2006-07-01--2008-05-01
The purpose of the study was to describe bruising as a marker of physical elder abuse. Consenting older adults were examined to document location and size of bruises and assess whether they were inflicted during physical abuse. An expert panel confirmed physical abuse. A research nurse conducted study assessments on 67 adults aged 65 and older reported to Adult Protective Services for suspected physical elder abuse in Orange County, California between July 2006 and May 2008. The study contains a total of 142 variables including age, sex, ethnicity, functional status, medical conditions, cognitive status, history of falls, bruise size, bruise location and color, recall of cause, and responses to the Revised Conflicts Tactics Scales (CTS2) and to the Elder Abuse Inventory (EAI).

The purpose of this study was to investigate violence and aggression committed by nursing home residents that is directed toward other residents, referred to here as resident-to-resident elder mistreatment (R-REM). Resident-to-resident mistreatment (R-REM) was defined as: negative and aggressive physical, sexual, or verbal interactions between long term care residents, that in a community setting would likely be construed as unwelcome and have high potential to cause physical or psychological distress in the recipient.

The goals of this project were to: enhance institutional recognition of R-REM; examine the convergence of R-REM reports across different methodologies; identify the most accurate mechanism for detecting and reporting R-REM; develop profiles of persons involved with R-REM by reporting source; investigate existing R-REM policies, and; develop institutional guidelines for reporting R-REM episodes. Also, the project team sought to answer the following research questions: (1) Will the reporting of R-REM differ by source? (2) Which reporting methods will show the highest level of convergence and accuracy in reporting? (3) What resident characteristics or profiles will predict R-REM across the differing reporting sources? (4) What are the existing guidelines and/or institutional policies for reporting R-REM? To achieve these goals, the researcher conducted this study over a two week period in five urban and five suburban New York City facilities. Resident-to-resident abuse information was derived from five sources: (1) resident interviews (2) staff informants (3) observational data (behavior sheets) (4) resident chart reviews (5) incident and accident reports.

Time period: 2014-09-01--2017-02-01

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed.

This study sought to: (1) document the spectrum of injuries and injury characteristics observed among physically-abused older adults reported to Adult Protective Services (APS) and compare those findings to injuries found among non-abused older adults, (2) identify observable injury characteristics and abuse circumstances that healthcare providers, law enforcement and prosecutors consider to be key forensic markers of physical abuse, (3) document information and evidence integral for achieving successful criminal prosecution, and (4) describe approaches that community-based frontline workers can employ to better document evidence of physical abuse.

The data included in this collection were collected under a National Institute of Justice-funded project that sought to document the spectrum and characteristics of injuries observed among physically abused, community-dwelling APS clients.

The collection includes two SAS datasets: injury.sas7bdat (with 47 variables and 403 cases) and subjectleveldata.sas7bdat (with 122 variables and 165 cases); and three SAS System Program Files: analysis-code-v1.sas, cleaned-injury-datasets-v1.sas, and formats.sas. Demographic variables in the collection are in the subjectleveldata.sas7bdat dataset, and include age, year of birth, gender, race, language, and level of education.

National Health Interview Survey, 1988: Occupational Health Supplement (ICPSR 6047)

Released/updated on: 1993-10-02
Geographic coverage: United States
The basic purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Each year, the National Center for Health Statistics conducts the NHIS, a personal interview household survey that uses a nationwide sample of the civilian, noninstitutionalized population of the United States. The NHIS includes a core set of questions that remains virtually unchanged across years on a variety of sociodemographic and health-related concerns. In addition, one or more current health topics is selected for special emphasis annually. For this supplement on occupational health, adult sample persons were asked questions regarding their lifetime working status and their work experience in the year prior to the interview. The primary focus of the supplement was on those individuals who had worked at civilian jobs in the prior year. These persons were asked about work-related injuries, back pain, hand discomfort, skin conditions, eye, nose, and throat irritations, health conditions, and smoking. Those who had previously worked, but not in the prior year, were asked questions about lifetime work experience, and then skipped to the questions on chronic conditions and smoking. Sample persons whose work during the prior year was active military duty also followed this sequence of questions. Those who had never worked were only asked about smoking. This collection also contains data from the basic questionnaire (see NATIONAL HEALTH INTERVIEW SURVEY, 1988 [ICPSR 9412]), including age, sex, race, marital status, education, veteran status, income, family relationship, self-reported health status, and activity limitations, and the number of bed days, doctor visits, and hospital stays in the previous year.

Released/updated on: 2016-08-05
Geographic coverage: United States

The National Health Interview Survey (NHIS) is conducted annually by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC). The main objective of the NHIS is to monitor the health of the United States population through the collection and analysis of data on a broad range of health topics.

The NHIS contains many similar questions every year. The repeated items are called "core questions." Beginning with a new NHIS design in 1997, these core questions were divided into three components -- Family, Sample Adult, and Sample Child.

The 2012 NHIS data release consists of six core data files, a paradata file, the three Disability Questions Tests files, a Functioning and Disability file, and two Complementary and Alternative Medicine files. Users may see the Survey Description document for more details.

The 2012 NHIS contains the core questions, as well as enhanced questions on health care access and utilization. Supplemental topics are covered in the following questionnaires: the Family questionnaire covers subjects of food security; the Sample Adult questionnaire covers subjects of immunization, complementary and alternative medicine, non-cigarette tobacco use, voice, speech, and language; and the Sample Child questionnaire covers subjects of mental health, mental health services, immunization, complementary and alternative medicine, balance, voice, speech, and language. Along with the 2012 NHIS core data files are the Disability Questions Tests 2012 files which contain person-level data collected via a field test of six disability questions. These supplemental questions appeared on the NHIS, at the end of the Family, Sample Adult, and Sample Child Cores.

The Disability Questions Tests 2012 files are released as three separate files. A fourth disability supplement was also fielded in 2012 as part of the Sample Adult Core and is called "Adult Functioning and Disability Level."

The Adult and Child Alternative Health Supplement files were intended to expand on knowledge of alternative medical services. Questions focus on how often various types of alternative therapies are used, the associated costs, and the reasons they are used.

Lastly, the Paradata Level file contains information about the survey and data collection processes; included are data on response rates, keystrokes, interview times, and number of contact attempts.

Part 9, Paradata Level, does not contain health related information, but rather data which are related to the interview process, including measures of time, contact-ability, and cooperation.

National Hospital Ambulatory Medical Care Survey, 1992 (ICPSR 6585)

Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1991-12-02--1992-12-27
The National Hospital Ambulatory Medical Care Survey (NHAMCS) was inaugurated in 1992 to fill a gap in data about ambulatory medical care in the United States. Although the National Ambulatory Medical Care Survey (NAMCS) collects annual data on patient visits to physician offices, it excludes the hospital emergency room and outpatient department visits that make up a large part of the total ambulatory care received each year. The 1992 NHAMCS provides data from samples of patient records selected from emergency departments (EDs) and outpatient departments (OPDs) of a national sample of hospitals. The resulting national estimates describe the use of hospital ambulatory medical care services in the United States. Between December 2, 1991, and December 27, 1992, data were collected from 314 OPDs and 437 EDs. Among the variables included are age, race, and sex of the patient, along with the reason for the visit, physician's diagnoses, cause of injury (ED only), surgical procedures (OPD only), medication therapy, and expected source of payment.

National Medical Expenditure Survey, 1987: Household Survey, Disability Days and Medical Conditions [Public Use Tape 29] (ICPSR 6473)

Released/updated on: 2006-03-30
Geographic coverage: United States
The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Household Survey was fielded over four rounds of personal and telephone interviews at four-month intervals. Baseline data on household composition, employment, and insurance characteristics were updated each quarter, and information on all uses of and expenditures for health care services and sources of payment was obtained. Public Use Tape 29 provides information on disability days and household-reported medical conditions for 1987. There are five data files in this collection. Part 1, Medical Conditions Data, contains one record for each medical condition reported by a respondent. Variables include information on whether the respondent saw or talked to a medical provider about the condition, beginning and ending dates of the condition, whether the condition was due to an accident, the body area affected by the condition, and whether the respondent or a doctor discovered the condition. In Part 2, Disability Days Data, a record represents a unique disability defined by the combination of disability type and disability period. Variables describe up to four different types of disabilities due to illness or injury that were collected over the four rounds of the interviews. The types of disabilities are work-loss days, school-loss days, bed days, and restricted-activity days. In addition, beginning and ending dates of the disability period, number of disability days, and medical conditions associated with the disability period are also included. Part 3, Disability Days to Medical Conditions Link File, contains the variables necessary to link each disability days record in Part 2 with one or more of the condition records in Part 1. Variables include the type of event this record links to, condition number, condition ID, event number, event ID, person ID, and provider number. Part 4, Medical Conditions to Medical Utilization and Expenditures Link File, contains the variables necessary to link each condition record in Part 1 with one or more of the records contained in NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: PRESCRIBED MEDICINE DATA [PUBLIC USE TAPE 14.1] (ICPSR 9746), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY DATA ON HOME HEALTH CARE AND MEDICAL EQUIPMENT PURCHASES AND RENTALS [PUBLIC USE TAPE 14.2] (ICPSR 9944), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY, DENTAL VISIT DATA [PUBLIC USE TAPE 14.3] (ICPSR 9814), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY, HOSPITAL STAYS DATA [PUBLIC USE TAPE 14.4] (ICPSR 9840), or NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: AMBULATORY MEDICAL VISIT DATA [PUBLIC USE TAPE 14.5] (ICPSR 9881). Variables include original dwelling unit, person number, person identifier, condition number, condition ID, event number and identifier, provider number, and type of event this record links to. Part 5, NMES Household Survey Modified ICD-9-CM Label File, contains a record for each of the condition codes reported in the NMES Household Survey and the Survey of American Indians and Alaska Natives (SAIAN).

National Mortality Followback Survey, 1993 (ICPSR 2900)

Released/updated on: 2005-02-21
Geographic coverage: United States
The National Mortality Followback Survey (NMFS) Program, begun in the 1960s by the National Center for Health Statistics (NCHS), uses a sample of United States residents who die in a given year, supplementing information derived from the death certificate with information from the next of kin or another person familiar with the decedent's life history. This information, sometimes enhanced by administrative records, is collected in order to study the etiology of disease, demographic trends in mortality, and other health issues. The 1993 National Mortality Followback Survey (NMFS) sampled individuals aged 15 years and over who died in 1993. Forty-nine of the 50 state vital registration areas, as well as the independent vital registration areas of the District of Columbia and New York City, granted approval to sample their death certificates. (South Dakota declined to participate due to a state law restricting the use of death certificate information.) A sample of 22,957 death certificates from 1993 was then drawn. To obtain reliable numbers for important population subgroups, such as persons under age 35, women, and the Black population, death certificates from those subgroups were oversampled. The 1993 NMFS survey focused on five subject areas: (1) socioeconomic differentials in mortality, (2) associations between risk factors and cause of death (use of tobacco, alcohol, drugs, firearms, motor vehicles), (3) disability (medical condition and cognitive functioning during the last year of life), (4) access and utilization of health care facilities during the last year of life (number of doctor visits, days bedridden, nursing home experiences, use of assistive medical devices, availability of health insurance), and (5) reliability of certain items reported on the death certificate. Demographic variables include age, gender, race, marital status, birthplace, education, occupation and industry, and income and assets. The 1993 NMFS survey differed from the previous mortality followback surveys in several ways: First, it emphasized deaths due to homicide, suicide, and unintentional injury. Second, the subject areas were considerably broader (many previously-surveyed subject areas, however, are included for trend analysis). This survey was also the first to acquire national-level information from medical examiners and coroners. Finally, the complexity of the questionnaire necessitated telephone or in-person interviews. The 1993 NMFS was designed in collaboration with other agencies of the Public Health Service, Department of Health and Human Services, and the National Highway Traffic Safety Administration.

RAND Survey of Compensation for Accidental Injuries in the United States, August 1987-August 1988 (ICPSR 3084)

Released/updated on: 2012-07-12
Geographic coverage: United States
Time period: 1987-08-01--1988-08-01
This survey was conducted in 1989 to look at the consequences of injuries that had occurred within the past year. The main purpose was to examine medical treatment, activity restriction, loss reimbursement, and decisions regarding liability claims related to accidental injuries. Work-related stress and injuries that were fatal, resulted in institutionalization, or were caused by pharmaceutical products were not included. Questions were posed regarding treatment following the accident, resulting impairment, rehabilitation expenditures, tort liability payment, insurance benefits, expected claims, and legal assistance, along with psychological and social consequences from making the claims. While many features of this study are comparable to both the Current Population Survey (CPS) and the National Health Interview Survey (NHIS), the RAND survey is different in that questions regarding liability-claiming behaviors were asked over the course of a year, and questions about visits to care providers were included. Demographic information on respondents consists of sex, age, and education.

The Survey of Health, Ageing and Retirement in Europe (SHARE) -- Israel, 2005-2006 (ICPSR 22160)

Released/updated on: 2008-11-21
Geographic coverage: Israel, Global
Time period: 2005-01-01--2006-01-01

The Survey of Health, Ageing and Retirement in Europe (SHARE) is a multidisciplinary and cross-national database of micro data on health, socio-economic status and social and family networks of individuals aged 50 or over which was designed after the role models of the United States Health and Retirement Study (HRS) and the English Longitudinal Study of Ageing (ELSA).

SHARE-Israel was added to the collection during 2005 and 2006 and required a complex adaptation of the SHARE survey instruments for implementation in Israel. In order to access the three major population groups that make up Israeli society, veteran Jewish-Israelis, Arab-Israelis and new immigrants from the former Soviet Union after 1989, it was necessary to translate the CAPI questionnaire and the drop off questionnaire into Hebrew, Arabic and Russian.

Data collected include health variables (e.g., self-reported health, physical functioning, cognitive functioning, health behavior, use of health care facilities), psychological variables (e.g., psychological health, well-being, life satisfaction), economic variables such as (current work activity, job characteristics, opportunities to work past retirement age, sources and composition of current income, wealth and consumption, housing, education), and social support variables (e.g., assistance within families, transfers of income and assets, social networks, volunteer activities).

Two physical performance measures were also employed. The first was grip strength, the respondent's maximum handgrip strength measured by means of a dynamometer. The second physical performance measure was walking speed, which was asked only of persons aged 75 and older. This physical measurement involved asking the respondent to walk a certain distance and measuring the time it took for the respondent to complete the task.

Unique to SHARE-Israel were questions in the drop-off questionnaire regarding trauma. Respondents were asked about difficult life events that they had experienced and the degree to which they were affected by them. The events were drawn from the following areas (1) having personally suffered injury in war, in a terrorist attack, a grave illness or accident, (2) having witnessed injury or death in war, in a terrorist attack, and/or in an accident or crime, (3) having been a victim of crime, abuse, sexual harassment and/or severe economic adversity, (4) having had a close person injured or lost due to war, a terrorist attack, accident or grave illness, (5) loss of spouse and/or offspring, and (6) having provided or received long term care due to functional disability. A separate inventory chronicled respondents' exposure to the Holocaust.

Also included in the drop-off questionnaire were questions regarding pension reform: which addressed respondents' awareness of the legislated delay in the age of eligibility for retirement pension in Israel, (for men, age 67 and for women, age 64). It also inquired about implications of the change in pension age, information regarding personal plans for employment or retirement in light of the change, and sources of income that would be used to bridge the period between retirement and receipt of pension, if early retirement was contemplated. Full details regarding SHARE can be located at the SHARE Web site.

Swedish Adoption/Twin Study on Aging (SATSA), 1984, 1987, 1990, 1993, 2004, 2007, and 2010 (ICPSR 3843)

Released/updated on: 2015-05-13
Geographic coverage: Sweden, Global
Time period: 1984-01-01--2010-01-01
The Swedish Adoption/Twin Study on Aging (SATSA) was designed to study the origins of individual differences in aging and the environmental and genetic factors that are involved. SATSA began in 1984, and six additional waves were conducted in 1987, 1990, 1993, 2004, 2007, and 2010. The questionnaire was initially sent to all twins from the Swedish Twin Registry who were separated at an early age and raised apart; the survey was also administered to a control sample of twins who were raised together. The respondents were surveyed on items that included health status, how they were raised, work environment, alcohol consumption, and dietary and smoking habits, as well as questions about personality and attitudes; this information comprised the first component. The second component was collected from a subsample composed of 150 pairs of twins raised apart and 150 pairs of twins raised together. This subsample participated in seven waves of in-person testing, which included a health examination, structured interviews, and tests on functional capacity, cognitive abilities, and memory. The data are represented according to questionnaire and time number, and correspond to each wave/year: Questionnaire 1 and In-Person Testing Time 1 were in 1984; Questionnaire 2 and In-Person Testing Time 2 were in 1987; Questionnaire 3 and In-Person Testing Time 3 were in 1990; Questionnaire 4 and In-Person Testing Time 4 were in 1993; Questionnaire 5 was in 2003; In-Person Testing Time 5 was in 2004; Questionnaire 6 and In-Person Testing Time 6 were in 2007; In-Person Testing Time 7 was in 2010. The Administrative and Cognitive datasets include data from all years/waves. The Smell Survey dataset only includes data from 1990. No years were specified for the Contact measures and Separation measures datasets. Demographic and background information includes age, sex, education, family history, household composition and employment.
