Insurance coverage, medical conditions, and visits to alternative medicine providers: results of a national survey.

BACKGROUND: In 1997, patients made an estimated 629 million visits to complementary and alternative medicine (CAM) providers; however, little is known about factors associated with visits to CAM providers. OBJECTIVE: To examine the effect of insurance coverage on frequency of use of CAM providers. METHODS: We conducted a nationally representative, random household telephone survey of 2055 adults. MAIN OUTCOME MEASURE: The number of visits made to CAM providers. RESULTS: An estimated 44% of the US population used at least 1 CAM therapy in 1997. Of those using CAM, 52% had seen at least 1 CAM provider in the last year. Among those who used a CAM therapy, factors independently associated with seeing a provider were having been in the upper quartile of visits to conventional providers in the last year (adjusted odds ratio [AOR], 2.00; 95% confidence interval [CI], 1.33-3.01), female sex (AOR, 1.67; 95% CI, 1.17-2.38), and having used the therapy to treat diabetes (AOR, 5.20; 95% CI, 1.40-19.40), cancer (AOR, 2.99; 95% CI, 1.04-8.62), or back or neck problems (AOR, 1.51; 95% CI, 1.02-2.23). Factors independently associated with frequent use (. or = 8 visits per year) of a CAM provider were full insurance coverage of the CAM provider (AOR, 5.06; 95% CI, 2.45-10.47), partial insurance coverage (AOR, 3.26; 95% CI, 1.72-6.19), having used the therapy for wellness (AOR, 2.85; 95% CI, 1.63-4.98), and having seen the provider for back or neck problems (AOR, 2.26; 95% CI, 1.29-3.94). Conservative extrapolation to national estimates suggests that 8.9% of the population (17.5 million adults) accounted for more than 75% of the 629 million visits made to CAM providers in 1997. CONCLUSIONS: A small minority of persons accounted for more than 75% of visits to CAM providers. Extent of insurance coverage for CAM providers and use for wellness are strong correlates of frequent use of CAM providers.

Confirming insurance coverage in a telephone survey: evidence from the National Survey of America's families.

Until recently, most surveys of insurance coverage have classified people as uninsured if they have not been assigned some coverage in response to one of a series of questions about specific types of insurance. This "residual" approach to measuring uninsurance rates has not required respondents to either verify their insurance status or confirm that they are uninsured. Using the 1997 National Survey of America's Families, this paper examines the impact of a question confirming whether individuals for whom no insurance coverage is reported are, in fact, uninsured. The results of our analysis suggest that a confirmation question as part of a telephone-based survey works to lower estimates of the uninsured.

Adolescent health insurance coverage: recent changes and access to care.

OBJECTIVE: To assess the health insurance status of adolescents, the trends in adolescent health care coverage, the demographic and socioeconomic correlates of insurance coverage, and the role that insurance coverage plays in influencing access to and use of health care. Together, the results provide a current and comprehensive profile of adolescent health insurance coverage. METHODS: We analyzed data on 14 252 adolescents, ages 10 to 18 years, included in the 1995 National Health Interview Survey. The survey obtained information on insurance coverage and several measures of access and utilization, including usual source of care, site of the usual source of care, indications of missed or delayed care, and use of ambulatory physician services by adolescents. We conducted multivariate analyses to assess the independent association of age, sex, race, poverty status, family structure, family size, region of residence, metropolitan resident status, and health status on the likelihood of insurance coverage. We conducted bivariate and multivariate analyses to ascertain how insurance coverage was related to each of the access and utilization measures obtained in the survey. We also examined trends in health insurance coverage using the 1984, 1989, and 1995 editions of the National Health Interview Survey. RESULTS: An estimated 14.1% of adolescents were uninsured in 1995. Risk of being uninsured was higher for older adolescents, minorities, adolescents in low-income families, and adolescents in single parent households. Compared with their insured counterparts, uninsured adolescents were five times as likely to lack a usual source of care, four times as likely to have unmet health needs, and twice as likely to go without a physician contact during the course of a year. Between 1984 and 1995 the percentage of adolescents with some form of health insurance coverage remained essentially unchanged. During this period, the prevalence of private health insurance decreased, while the prevalence of public health insurance increased. CONCLUSIONS: This study demonstrates the critical importance of health insurance as a determinant of access to and use of health services among adolescents. It also shows that little progress has been made during the past 15 years in reducing the size of the uninsured adolescent population. The new State Children's Health Insurance Program could lead to substantial improvements in access to care for adolescents, but only if states implement effective outreach and enrollment strategies for uninsured adolescents.adolescents, health insurance, access, Medicaid, SCHIP.

Health insurance coverage and physician use among children with disabilities: findings from probability samples in five metropolitan areas.

The effect of insurance coverage on physician use for children in the United States who have been identified as disabled by their schools under the provisions of the Education for All Handicapped Children Act (PL 94-142) is examined. The research is based on identically drawn stratified random samples of children from the elementary school special education populations of five large metropolitan school systems. It was found that health insurance coverage was a predictor of whether a disabled child had seen a doctor in the past year even after adjustment for site, family background characteristics, type and severity of childhood disability, and structural access factors (adjusted odds ratio, 1.76, P less than .05); Hispanic children with disabilities were more likely than white children to be without any health insurance (adjusted odds ratio, 3.63; P less than .001), but there was no similar statistically significant difference between blacks and whites; and wide variations persist in scope of insurance payment for care, such that parents of publicly insured children paid out of pocket for only 5% of all physician visits as compared to 30% of visits for the privately insured. Even for children with various low-prevalence disabilities, when privately insured, parents paid out of pocket for 23% of all physician visits. These data help clarify the extent of health insurance coverage among children with disabilities and indicate that insurance remains an important predictor of physician use even though it continues to pay for only certain elements of care.

[New trends in home oxygen therapy (HOT) after the introduction of health insurance coverage in Okinawa and factors contributing to long-term survival].

A total of 179 cases given HOT after introduction of health insurance coverage in 1985 were reported from 12 medical institutes in Okinawa and were compared with 110 cases followed at Okinawa Chubu Hospital during 1976-1985, prior to insurance coverage. The number of patients on HOT have rapidly increased after insurance coverage not only in our institute but also in other institutes in Okinawa and the patients with emphysema formed the largest group. The oxygen enricher is now utilized more than the compressed gas system, accounting for about 70% of all patients compared with the previous figure of 7.3%. Average PaO2 on room air was higher (from 42 Torr to 49 Torr) and the levels of PaO2 maintained by HOT had 2 peaks, one in the 60-65 Torr range and the other in the 75-80 Torr range in patients newly given HOT. The patients with emphysema, who had the worst prognosis in the past, remarkably improved and showed no statistical difference from patients with chronic bronchitis or bronchiectasis in terms of long-term survival. The female patients had better prognosis than males, but the reason is still unclear to us. The absolute volume of FEV1.0 and the presence or absence of cor pulmonale have not affected the long-term survival. A group of the patients with CO2 retention (bronchitic in type) did not benefit from HOT in terms of long-term survival unless their PaO2 levels on room air were below 50 Torr and it was felt that PaO2 levels of 50-59 were too mild in severity for application of HOT.(ABSTRACT TRUNCATED AT 250 WORDS)

Millions of mothers lack health insurance coverage in the United States. Most uninsured mothers lack access both to employer-based coverage and to publicly subsidized health insurance.

Some 5.9 million American mothers caring for young or school-aged children lack health insurance. Although nearly nine in ten uninsured mothers are members of working families, most lack access to affordable coverage through their job or a spouse's job. Most are ineligible for publicly subsidized coverage unless their incomes are far below the poverty line. The millions of uninsured mothers are at high risk of going without needed preventive and primary care. If they become seriously ill, their families can face the prospect of a financial crisis. The nation has made significant progress in extending health care coverage to children in low-income families through Medicaid and the State Children's Health Insurance Program (SCHIP), but no comparable effort has been made to insure the mothers of these children. A few states have started to address the problem by transforming their SCHIPs into family-based programs that also cover low-income parents. Bipartisan legislation under consideration, known as FamilyCare, would encourage this trend by providing more federal funding to states that could be used to extend health insurance to the parents of children already covered by publicly funded programs.

The effect of employment status on private health insurance coverage: 1977 and 1987.

Analyzing cross-sectional data from the National Medical Expenditure Survey (NMES), we find that the predicted probability of private insurance coverage for low-income individuals as a group fell dramatically from 1977 to 1987. The results of a decompositional technique show that the relationship between full-time employment and private insurance has weakened over the period for low-income females, but has strengthened for males in this group. While it appears that low-income females benefit from part-time employment relative to their unemployed cohorts, no discernible difference is found in the likelihood of being covered by private insurance for part-time and unemployed males. Finally, evidence suggesting a weakening over time in the relationship between part-time employment and private insurance coverage is found among middle-income females and high-income males. From a policy perspective, passage of the Health Insurance Portability and Accountability Act of 1996 has taken an important first step in attempting to lower the number of uninsured, especially among full-time workers. Our findings, however, suggest that this legislation may be too limited in scope to effectively reach part-time workers presently uninsured.

Expanding health insurance coverage and the implications for dentistry.

Numerous proposals have been suggested for expanding health insurance coverage to the over 30 million Americans without health insurance. These proposals range from establishing a program of national health insurance modeled after the Canadian system to establishing statewide risk pools. Many of these proposals could have an impact on financial access to dental care for the approximately 120 million people without dental insurance. Dental insurance coverage has been shown to increase access to dental services and improve oral health status. Oral health professionals could facilitate discussions concerning health insurance expansion by informing policymakers about important preventive benefits to be gained by improving access to dental services. Dental public health professionals can serve as a bridge between organized dentistry and health policymakers by providing information to help formulate the priorities and characteristics of a dental health insurance program. This visibility and influence in the health policy arena would be beneficial to dentistry and could ultimately result in greater access to dental services and improved oral health for the uninsured.

Knowledge of their health insurance coverage by the elderly.

Current legislative proposals to increase competition among private insurers assume that people are or can be well-informed about their insurance coverage. Evidence from the National Medical Care Expenditure Survey shows that among the population 65 years of age and older knowledge about health insurance coverage is substantial but generally lower than in the population younger than 65 years of age. Multivariate analysis is used to identify factors associated with high and low levels of knowledge. Although correct knowledge of coverage of particular services is highly associated with current experience of health problems, with use of these health services, and with the cost for private insurance, overall knowledge is lowest among some groups at high risk of serious illness, in particular, the old, nonwhites, and persons enrolled in Medicare but without Medicaid or private insurance supplements.

The impact of insurance coverage on children's dental visits and expenditures, 1996.

BACKGROUND: Health insurance coverage has been shown to relate positively with the use of dental services. The purpose of the authors' study was to describe the level of dental coverage among U.S. children and to assess the impact of dental coverage on children's use of dental services and expenditures for dental care. METHODS: The focus of these analyses is on dental care coverage, use and expenditures for U.S. children during 1996. National estimates are provided for the population with dental coverage, the population with a dental visit, and mean total expenditure for each of several socioeconomic and demographic categories during 1996 using data from the Medical Expenditure Panel Survey. RESULTS: Fifty-two percent of children younger than 18 years of age had private dental coverage during 1996. Approximately 56 percent of children in families with a poverty status level of 133 percent of the federal poverty level or below were covered by Medicaid during 1996. Fifty-six percent of children with private coverage had made at least one dental visit, compared with 28 percent of noncovered children. Twenty-eight percent of children covered by Medicaid had made at least one dental visit compared with 19 percent of noncovered children. CONCLUSION: Medicaid dental coverage seems to have had a lesser effect on the likelihood of a child's having a dental visit than had private coverage. Improving oral health for poorer children may depend partly on improving the design of Medicaid dental coverage programs. PRACTICE IMPLICATIONS: By understanding these analyses, practitioners, advocates and policymakers will be better positioned to provide care, improve access and better meet the needs of all American children.

The extent of private and public health insurance coverage among adult Hispanics.

Data from the Health and Retirement Survey reveal extremely low levels of health insurance coverage among Hispanics and, especially, among Mexican Americans. The data reveal that this lack of insurance is associated with lower rates of employer-based and privately purchased coverage. Even after controlling for a large number of insurance-related factors, Hispanics have rates of health insurance coverage that are lower than those of either non-Hispanic blacks or whites. This serious lack of health insurance coverage among preretirement-age Hispanics has serious implications both for health, because the lack of insurance represents a major barrier to health care, and for the adequacy of retirement coverage, because private insurance represents an important supplement to Medicare.

The marginal benefits of invasive treatments for acute myocardial infarction: does insurance coverage matter?

This paper applies instrumental variable (IV) techniques and estimates the average benefits of invasive surgical treatments for marginal acute myocardial infarction (AMI) patients by insurance coverage. The study uses data from the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project (HCUP), State Inpatient Databases for the state of Washington, for years 1988-1993. We observed differences in average benefits for marginal patients across insurance subpopulations that cannot be explained by differences in measured clinical circumstances. Our empirical results show that the insurance subpopulations with the greatest estimated marginal benefits are those with the lowest expected payment generosity to providers. Because of the relatively weak explanatory power of our instruments for three insurance subpopulations, and because many of the parameter estimates across the insurance subpopulations are not statistically different from each other, policy recommendations should be approached cautiously. However, our application of IV techniques to AMI patients demonstrates the usefulness of this approach to estimate treatment effects across patient populations (e.g., across types of insurance coverage) for medical conditions of interest to policymakers. These estimates may help determine whether treatments are overutilized or underutilized.

[Insurance coverage in repetitive strain injury of the upper limbs as provided by the National Insurance Institute for Occupational Diseases].

A brief outline is given of the current status of the insurance "coverage" provided by INAIL for WMSDs. In breach of a specific European Union recommendation, in Italy various WMSDs can be recognised as occupational only based upon sentence No 179/88 of the Constitutional Court, since such disorders are not included in the list attached to DPR law 336/94. At present, during the period 1990-95, INAIL awarded indemnities in only a handful of cases. Details are provided concerning the evidence that must be submitted in the specific case of claims pertaining to suspected occupational diseases. The authors discuss the problems associated with quantifying injuries for the purposes of claiming indemnities for work-related musculo-skeletal disorders.

Transforming insurance coverage into quality health care: voltage drops from potential to delivered quality.

Although the US health care system is often touted as one of the best in the world, disparities exist in quality of care received by different populations, in different regions, and across different institutions and clinicians. Initiatives to provide access to health insurance have been a major policy tool to ensure that Americans receive high-quality health care. However, availability of insurance coverage does not automatically lead to high-quality care. This article explores points of vulnerability in the US health care system at which the potential to achieve high-quality care can be lost: (1) access to insurance coverage; (2) enrollment in available insurance plans; (3) access to covered services, clinicians, and health care institutions; (4) choice of plans, clinicians, and health care institutions; (5) access to a consistent source of primary care; (6) access to referral services; and (7) delivery of high-quality health care services. Ensuring high-quality health care requires that each of these "voltage drops" be recognized and addressed. JAMA. 2000;284:2100-2107.

Health insurance coverage of adolescents: a current profile and assessment of trends.

Data from the National Health Interview Survey reveal that 4.7 million or 15% of US adolescents aged 10 through 18 were uninsured in 1989. Among adolescents, 73% were privately insured, 10% were publicly insured, and 2% were both privately and publicly insured. Poor, near-poor, and minority adolescents were at the greatest risk for lack of health insurance coverage. Among adolescents without insurance, cost continued to be cited as the leading barrier to obtaining coverage. A comparison of 1989 National Health Interview Survey data with a previous analysis, in which 1984 data were used, revealed a 10% increase in the proportion of adolescents without insurance coverage. The increase in the proportion of uninsured adolescents was entirely attributable to an erosion of private health insurance coverage. No significant change occurred in the proportion of adolescents with coverage under public programs. Planned expansions of the federally and state-financed Medicaid programs will help to stem further increases in the size of the uninsured adolescent population. However, unless marked improvements occur in the private health insurance sector, progress will be limited.

A shifting picture of health insurance coverage.

Data from the Current Population Survey are used in this DataWatch to explore the changing composition of health insurance coverage of the U.S. nonelderly population. The authors analyze coverage trends across various subpopulations for 1988-1993. During this time significant declines in employer-sponsored coverage coincided with equally significant increases in Medicaid coverage. Thus, the increase in the proportion of nonelderly persons without health insurance appears relatively small. However, this analysis reveals that the relative stability of the uninsurance rate for the entire nonelderly population belies more significant changes in insurance coverage--and lack of coverage--among various groups. The authors also discuss the extent to which a growing level of public insurance "crowds out" (or substitutes for) private health insurance.

Explaining the decline in health insurance coverage among young men.

This article examines the experience of cohorts of young American men to see how and why their employer-provided health insurance coverage has changed over time. It explores changes in the structure of the labor market, changes in the cost of employer-provided health insurance, and changes in the composition of wages and benefits offered to employees. We find that increases in the cost of health insurance rather than changes in the structure of the labor market are the principal cause of the observed decline in employer-provided health insurance coverage across all cohorts.
