The time required to decide to seek medical care for acute chest pain is the major modifiable component in the process of care delivery. This study demonstrates that prehospital delay in the setting of acute chest pain was related to the type of health insurance.
With few exceptions, most organ transplantation procedures are expensive, although there is considerable variability in costs across transplantation programs. Because of their high cost, many public and private insurers are in the process of carefully evaluating their transplantation coverage and reimbursement policies. Some public insurers have decided to discontinue paying for some procedures on grounds that the resources expended on transplantation could be used to benefit a larger number of people without catastrophic disease. Thus, transplantation is being pitted against health promotion and disease prevention initiatives. Some insurers have also been reluctant to pay for selected transplants, arguing that they are "experimental" or "investigational." Pancreas, lung, and heart-lung transplants are often classified as such. While these decisions have a reasonable basis, concerns related purely to cost, not benefit, have made insurers hesitant to extend coverage to procedures they view as inefficacious. Transplantation programs performing pancreas, heart-lung, and lung transplantation, therefore, do so at some risk. They may not be reimbursed for the procedures they perform, or, more likely, the level of payment received is likely to be substantially below actual hospital costs. To control costs, insurers have also begun to designate transplantation centers. In doing so they limit coverage and reimbursement to programs they regard as "centers of excellence." To become a designated center, a transplantation program must meet preestablished volume and outcome requirements, which insurers believe will assure quality and minimize costs. Thus, designated centers are expected to provide cost-effective transplantation services. If insurers choose to regionalize transplantation programs, controlling both their number and distribution, it is quite possible that patient access to transplantation, as well as their choice of provider, will be severely constrained. In conclusion, concerns related to transplantation costs undoubtedly will have enormous implications for the delivery of transplantation services throughout the foreseeable future. Most significantly, the number of "qualified" centers, using insurer criteria, may be restricted to a small subset of currently active programs. This could have a dramatic affect on the start-up of new programs and the continuation of others.
We describe an evaluation model to guide public coverage of new predictive genetic tests in Ontario, Canada. The model confronts common "gray zones" in evaluation and coverage policy for challenging new technologies. Analysis addresses three domains of the evaluation picture. The first specifies evaluative criteria (purpose, effectiveness, additional effects, unit cost, demand, cost-effectiveness). The second induces or deduces acceptable cutoffs for each criterion. The third domain addresses the need to make decisions under uncertainty and to respond to "gray" evaluations with conditional-coverage decisions. The evaluation criteria should be applied within sound decision-making processes.
OBJECTIVE: Based on the assumption that people without health insurance have limited access to the primary care services needed to prevent unnecessary hospitalizations for asthma, the authors hypothesized that insurance is a factor in the strength of the association between hospital admissions for asthma and exposure to air pollution. They tested this hypothesis with 1991-1994 data from central Los Angeles. METHODS: The authors analyzed the effect of insurance status on the association between asthma-related hospital admissions and exposure to atmospheric particulates (PM10) and ozone (O3) using hospital discharge and air quality data for 1991-1994 for central Los Angeles. They used regression techniques with weighted moving averages (simulating distributed lag structures) to measure the effects of exposure on overall hospital admissions, admissions of uninsured patients, admissions for which MediCal (California Medicaid) was the primary payer, and admissions for which the primary payer was another government or private health insurance program. RESULTS: No associations were found between asthma admissions and O3 exposure. An estimated increase from 1991 to 1994 of 50 micrograms per cubic meter in PM10 concentrations averaged over eight days was associated with an increase of 21.0% in the number of asthma admissions. An even stronger increase--27.4%--was noted among MediCal asthma admissions. CONCLUSIONS: The authors conclude that low family income, as indicated by MediCal coverage, is a better predictor of asthma exacerbations associated with air pollution than lack of insurance and, by implication, a better predictor of insufficient access to primary care.
In the United States during 1994, approximately 49% of all pregnancies, excluding miscarriages, were unintended. Unintended pregnancy can result in adverse health outcomes that affect the mother, infant, and family. Little is known about the distribution of unintended pregnancy with respect to the payment source for health care. In the absence of data for periconceptional payment source for health care, prenatal-care payment source is used as a surrogate. To develop recommendations to reduce unintended pregnancy, CDC analyzed insurance coverage-specific prevalences of live-born infants from unintended pregnancies among women aged 20-34 years using data from the Pregnancy Risk Assessment and Monitoring System (PRAMS) for 1996 (the most recent year for which data are available). This report summarizes the results of this analysis, which indicates that the highest rates of unintended pregnancy occurred among women covered by Medicaid, with lower rates among women covered by health-maintenance organizations (HMOs) or private insurance.
This paper describes the effects of health financing systems (insurance) on outpatient drug use in rural China. 1320 outpatients were interviewed (exit interview) in the randomly selected county, township and village health care facilities in five counties in three provinces of central China. The interview was face to face. Questions were asked by a trained interviewer and were answered by patient him/herself. The main finding was that health insurance appeared to influence drug use in outpatient services. The average number of drugs per visit was 2.56 and drug expenditures per visit was 16.9 yuan. Between insured and uninsured (out-of-pocket) groups, there were significant differences in the number of drugs and drug expenditures per visit. The insured had a lower number of drugs and a higher drug expenditure per visit than the uninsured, implying the use of more expensive drugs per visit than the uninsured. There were also significant differences in the number of drugs and drug expenditures per visit between the types of insurance. One third of the drugs were anti-infectives, most of which were penicillin, gentamycin, and sulfonamides. The results imply that uninsured patients do not receive the same care as the insured do even if they have the same needs. The fee-for-service financing for hospitals and health insurance have changed health providers' and consumers' behaviour and resulted in the increase of medical expenditure.
The research reported in this paper examines the decision to have private health insurance by elderly Medicare enrollees. Models allowing both stimultaneity and a joint error structure between health insurance and use of medical care are considered. We find that common unobserved variables underlying the joint errors are important determinants in the decision to purchase private health insurance. Simultaneity is present only between the decision to have private health insurance and the probability of visiting a doctor. Health status and functional limitations are important determinants of the decision to have private health insurance in addition to Medicare coverage. Other personal characteristics (age, sex, race and education), as well as household income, Medicaid enrollment, and the employment of a family member are also found to be related to the decision to have private health insurance.
BACKGROUND: Despite good evidence that their smoking-cessation actions can be very effective, physicians have not consistently used the 5A actions (being asked, advised, assessed, assisted, and arranged) recommended in the U.S. Public Health Service tobacco guidelines. We tested the hypothesis that the introduction of coverage for smoking-cessation pharmacotherapy by the health plans covering most of the population in one region would increase physician use of 5A's. METHODS: A cohort of smoking members of two health plans was surveyed before and after the introduction of coverage for smoking cessation. A total of 1560 current smokers with a physician visit in the last year responded to both surveys. The key outcome measures were smoker reports of the guideline 5As for smoking-cessation support during the last physician visit. RESULTS: There were small significant absolute percentage increases only for reports of being assessed (+4.9%, p=0.01) and assisted (set quit date +6.5%, p=0.0004); encouraged to use medications (+8.8%, p=0.03); and given a prescription (+8.6%, p=0.0005). However, these increases were limited to smokers reporting awareness of the coverage, asking for quitting help, or both. CONCLUSION: Coverage for pharmacotherapy alone appears to have had no effect on physician behavior beyond that stimulated by smokers who were aware of the coverage, perhaps because they raised the issue. More research is needed on this suggestion that patients create physician behavior change.
In a decision released in August 1999, the Health Services Appeal Board in Ontario upheld the decision to deny provincial health coverage to an HIV-positive woman who had been denied permanent resident status on the basis of "medical inadmissibility" but was living in Canada on an Immigration Minister's Permit issued on "humanitarian and compassionate grounds."

The Federal Employees Health Benefits Program (FEHBP) could be combined with health insurance tax credits to extend coverage to the uninsured. An extended FEHBP, or "E-FEHBP," would be open to all individuals who were not covered through work or public programs and who also were eligible for the tax credits on the basis of income. E-FEHBP also would be open to employees of very small firms, regardless of their eligibility for tax credits. Most plans available to FEHBP participants would be required to offer enrollment to E-FEHBP participants, although premiums would be rated separately. High-risk individuals would be diverted to a separate high-risk pool, the cost of which would be subsidized by the federal government. E-FEHBP would be administered by the states, or if a state declined, by an entity that contracted with the Office of Personnel Management. While E-FEHBP would provide group insurance to people who otherwise could not get it, premiums could exceed the tax-credit amount and some people still might find the coverage unaffordable.
OBJECTIVE: To assess the accuracy of data on "expected source of payment" in the patient discharge database compiled by the California Office of Statewide Health Planning and Development (OSHPD). DATA SOURCES: The OSHPD discharge data for the years 1993 to 1996 linked with administrative data from the University of California (UC) health benefits program for the same years. The linked dataset contains records for all stays in California hospitals by UC employees, retirees, and spouses. STUDY DESIGN: The accuracy of the OSHPD data is assessed using cross-tabulations of insurance type as coded in the two data sources. The UC administrative data is assumed to be accurate, implying that differences between the two sources represent measurement error in the OSHPD data. We cross-tabulate insurance categories and analyze the concordance of dichotomous measures of health maintenance organization (HMO) enrollment derived from the two sources. PRINCIPAL FINDINGS: There are significant coding errors in the OSHPD data on expected source of payment. A nontrivial percentage of patients with preferred provider organization (PPO) coverage are erroneously coded as being in HMOs, and vice versa. The prevalence of such errors increased after OSHPD introduced a new expected source of payment category for PPOs. Measurement problems are especially pronounced for older patients. Many patients over age 65 who are still covered by a commercial insurance plan are erroneously coded as having Medicare coverage. This, combined with the fact that during the period we analyzed, Medicare HMO enrollees and beneficiaries in the fee-for-service (FFS) program are combined in a single payment category, means that the OSHPD data provides essentially no information on insurance coverage for older patients. CONCLUSIONS: Researchers should exercise caution in using the expected source of payment in the OSHPD data. While measures of HMO coverage are reasonably accurate, it is not possible in these data to clearly identify PPOs as a distinct insurance category. For patients over age 65, it is not possible at all to distinguish among alternative insurance arrangements.
