Community Hospital Program (CHP) Access Impact Evaluation Surveys, 1978-1979, 1981 (ICPSR 8245)

Released/updated on: 2006-01-12

Geographic coverage: United States

Time period: 1978-01-01--1979-01-01

This data collection evaluates group medical practices and the ways in which they affect both access to and use of medical services. Group practices, sponsored by the Robert Wood Johnson Foundation Community Hospital Program (CHP), were selected for use in this assessment. The data were collected by the Center for Health Administration Studies at the University of Chicago, with the assistance of Chilton Research Services. Two surveys were conducted for the study: a baseline survey in 1978-1979 and a follow-up in 1981. Community residents and CHP patients in 12 communities were interviewed. Demographic and medical care data were collected for selected individuals and families in the survey areas. Data on regular sources of medical care for individuals include the type of organization used, type of practice, accessibility, frequency of visits, types of health care professionals seen, cost, and satisfaction. Also in the collection are data on perceived health, episodes of illness (including symptoms, duration, disability days, and doctors consulted), use of preventive health care services, and insurance coverage. Demographic data for individuals and families include age, sex, race, educational attainment, employment, and income. Of the 198 files in this collection, 88 are "raw" data files and 110 are frequencies. The data files consist of four types. The first type are Sample Person files. These contain the responses of group practice patients and community members. The second type are Doctor Episode files, which record doctors and episodes of illness. Family files make up the third type of file, and consist of family members' responses to the survey. Analysis files, linking patient and doctor data, are the fourth type of file. The SPSS frequency files correspond to the data files: two per file for the Sample Person files, and one per file for the remaining three types of files.

Community Tracking Study Household Survey, 1996-1997, and Followback Survey, 1997-1998: [United States] (ICPSR 2524)

Released/updated on: 2024-02-14

Geographic coverage: United States

Time period: 1996-07-01--1997-07-01, 1997-10-01--1998-08-01

This data collection comprises two components of the Community Tracking Study (CTS), the Household Survey and the Followback Survey. The CTS, sponsored by the Robert Wood Johnson Foundation, is a national study designed to track changes in the health care system and their effects on care delivery and individuals. Central to the design of the CTS is its community focus. Sixty sites (51 metropolitan areas and 9 nonmetropolitan areas) were randomly selected to form the core of the CTS and to be representative of the nation as a whole. The Household Survey was administered to households in the 60 CTS sites and to a supplemental national sample of households. At the beginning of each interview, a household informant was identified and queried about the composition of the household. With this information, individuals in the household were grouped into family insurance units (FIU). An FIU reflects family groupings typically used by insurance carriers. It includes an adult household member, his or her spouse, if any, and any dependent children 0-17 years of age (or 18-22 years of age if a full-time student). Family informants, selected from each FIU in the household, provided information on health insurance coverage, health care use, usual source of care, and the general health of all persons in the FIU. These informants also provided information on family income and out-of-pocket expenses for health care, as well as employment, race, and Hispanic origin for all adult FIU members. Each adult in the household, including the FIU informants, responded through a self-response module to questions regarding unmet health care needs, patient trust, satisfaction with physician choice, limitations in daily activities, smoking behaviors, and last doctor visit. In FIUs with more than one child under 18, only one child was randomly selected for inclusion in the survey. The family informant responded on behalf of the child regarding unmet needs and satisfaction with physician choice. The adult family member who took this child to his or her last doctor visit responded to questions about the visit. The Followback Survey was designed to obtain detailed information on private health insurance coverage reported in the Household Survey. It was administered to health plans and other organizations that offered or administered the comprehensive private health insurance policies covering Household Survey respondents in the 60 CTS sites. Information on private health insurance policies collected by the Followback Survey includes product type, gatekeeping, consumer cost sharing, provider payment methods, and coverage of mental health and/or substance abuse services.

Community Tracking Study Household Survey, 1998-1999, and Followback Survey, 1998-2000: [United States] (ICPSR 3199)

Released/updated on: 2024-02-14

Geographic coverage: United States

Time period: 1998-01-01--2000-01-01

This collection comprises the second round of the Community Tracking Study (CTS) Household Survey and the second round of the CTS Followback Survey. The CTS, sponsored by the Robert Wood Johnson Foundation, is a national study designed to track changes in the health care system and their effects on care delivery and individuals. Fifty-one metropolitan areas and nine nonmetropolitan areas were randomly selected to form the core of the CTS and to be representative of the nation as a whole. As in the first round of the Household Survey (COMMUNITY TRACKING STUDY HOUSEHOLD SURVEY, 1996-1997, AND FOLLOWBACK SURVEY, 1997-1998: [UNITED STATES] (ICPSR 2524)), the second round of the Household Survey was administered to households in the 60 CTS sites and to a supplemental national sample of households. Respondents provided information about household composition and demographic characteristics, health insurance coverage, use of health services, unmet health care needs, out-of-pocket expenses for health care, usual source of care, patient trust and satisfaction, last visit to a medical provider, health status and presence of chronic health conditions, risk behaviors and smoking, and employment, earnings, and income. The purpose of the Followback Survey was to obtain detailed information on private health insurance coverage reported in the Household Survey. It was administered to the health plans and other organizations (managed care organizations, third-party administrators, employer or union plans, and employers) that offered or administered the respondents' comprehensive private health insurance policies. Information on private health insurance policies collected by the Followback Survey includes product type, gatekeeping, consumer cost sharing, provider payment methods, and coverage of mental health and/or substance abuse services.

Health Tracking Household Survey, 2007 [United States] (ICPSR 26001)

Released/updated on: 2011-04-15

Geographic coverage: United States

The 2007 Health Tracking Household Survey (HTHS) is the successor to the Community Tracking Study (CTS) Household Surveys which were conducted in 1996-1997 (ICPSR 2524), 1998-1999 (ICPSR 3199), 2000-2001 (ICPSR 3764), and 2003 (ICPSR 4216). Although the HTHS questionnaires are similar to the CTS Household Survey questionnaires, the HTHS sampling design does not have the community focus intrinsic to CTS. Whereas the CTS design focused on 60 nationally representative communities with sample sizes large enough to draw conclusions about health system change in 12 communities, the HTHS design is a national sample not aimed at measuring change within communities. Hence, "Community" was dropped from the study title. Like the CTS Household Surveys, HTHS collected information on health insurance coverage, use of health services, health expenses, satisfaction with health care and physician choice, unmet health care needs, usual source of care and patient trust, health status, adult chronic conditions, height and weight, and smoking behavior. In addition, the survey inquired about perceptions of care delivery and quality, problems with paying medical bills, use of in-store retail and onsite workplace health clinics, patient engagement with health care, sources of health information, and shopping for health care.

At the beginning of the interview, a household informant provided information about the composition of the household which was used to group the household members into family insurance units (FIU). Each FIU comprised an adult household member, his or her spouse or domestic partner (same sex and other unmarried partners), if any, and any dependent children 0-17 years of age or 18-22 years of age if a full-time student (even if living outside the household). In each FIU in the household, a FIU informant provided information on insurance coverage, health care use, usual source of care, and general health status of all FIU members. This informant also provided information on family income as well as employment, earnings, employer-offered insurance plans, and race/ethnicity for all adult FIU members. Moreover, every adult in each FIU (including the FIU informant) responded through a self-response module to questions that could not be answered reliably by proxy respondents, such as questions about unmet needs, assessments of the quality of care, consumer engagement, satisfaction with physician choice, use of health information, health care shopping, and detailed health questions. The FIU informants responded on behalf of children regarding unmet needs, satisfaction with physician choice, and use of health care information.

This is the second survey in the Health Tracking Household Survey (HTHS) series, the successor to the Community Tracking Study (CTS) Household Surveys. The CTS Household Surveys were conducted in 1996-1997 (ICPSR 2524), 1998-1999 (ICPSR 3199), 2000-2001 (ICPSR 3764), and 2003 (ICPSR 4216), and the first HTHS survey was conducted in 2007 (ICPSR 26001).

National Studies of Physicians from Twenty-four Medical and Surgical Specialties, 1976-1978 (ICPSR 7782)

Released/updated on: 2006-01-18

Geographic coverage: United States

Time period: 1976-01-01--1978-01-01

This study was conducted in order to gather detailed specialty-specific data for most of the physician population of the United States. Each member of sample groups of physicians in each of 24 specialty areas completed numerically coded "log diaries" (self-enumerated questionnaires) over the course of one week during the survey data gathering period of 1976-1978. With the information obtained from the log diaries, three data files containing detailed information on the activities of the physicians surveyed and on the characteristics of their practices were prepared for each of the 24 specialty areas: allergy, cardiology, dermatology, emergency medicine, endocrinology, family practice, gastroenterology, general practice, general surgery, hematology, infectious diseases, internal medicine, nephrology, neurological surgery, neurology, obstetrics/gynecology, oncology, ophthalmology, orthopaedic surgery, otorhinolaryngology, pediatrics, psychiatry, pulmonary diseases, and rheumatology. As a result, there are 71 discrete datafiles in this dataset (emergency medicine has only two files). Parts 1-24 contain detailed information about each physician's medical or surgical practice, e.g., specialty, major professional activity, board certifications, type of practice, physician's opinion concerning distribution of specialties in the community, number of hours per week worked and in what capacity, and type of employees in physician's practice and number of hours worked. Parts 28-48 contain data on each patient the physician saw in person during the week in which he or she kept the log diary. Parts 49-71 hold the data derived from each encounter the physician had via telephone with a patient during the same period. The data in the latter two groups of files contain patient age, sex, problem focus, role, source, and diagnoses.

Robert Wood Johnson Foundation Family Health Insurance Survey, 1993 (ICPSR 6894)

Released/updated on: 2005-06-22

Geographic coverage: Oregon, Vermont, New York, United States, New Mexico, Oklahoma, Colorado, Minnesota, Florida, North Dakota, Washington

Time period: 1993-01-01--1994-01-01

This survey investigated health insurance coverage, as well as access to and use of health services, in each of ten states. With the goal of remedying the previous lack of state-level data, the survey was conducted to aid in defining problems of insurance coverage and to analyze the impacts of states' policy options. The main unit of observation is the health insurance family, which includes the head, spouse, and their children up to age 18, or to age 23 if they were in school. Variables on health insurance coverage include the types of coverage respondents carried (Medicare, Medicaid, additional state or federal programs, and private policies), sources of private policy coverage, premiums paid for private policies, and number of months uninsured during the last year. Access to health care is measured by variables such as the type of usual health care provider, the amount of time it usually took to get to the doctor's office, and whether needed medical care was not received during the previous year. Variables on the utilization of health care include the number of overnight hospital stays, the number of visits to doctors, age at first DPT (diphtheria, whooping cough, and tetanus) shot, age at first oral polio immunization, and the number of months since the most recent breast exam and Pap smear. The survey also elicited self-reported health status and opinions on the health care system, gauged satisfaction/dissatisfaction with health services received, and gathered information on employment, income, education, migration, age, sex, marital status, race, Hispanic origin, and citizenship.
