Risk pooling and regulation: policy and reality in today's individual health insurance market

Analysis of new data on the relationship between and premiums and coverage in the individual insurance market and health risk shows that actual premiums paid for individual insurance are much less than proportional to risk, and risk levels have a small effect on obtaining coverage. States limiting risk rating in individual insurance display lower premiums for high risks than other states, but such rate regulation leads to an increase in the total number of uninsured people. The effect on risk pooling is small because of the large amount of risk pooling in unregulated individual insurance.

Group premiums in micro health insurance experiences from Tanzania

OBJECTIVE

The main objective was to assess how group premiums can help poor people in the informal economy prepay for health care services.

METHODS

A comparative approach was adopted to study four groups of informal economy operators (cobblers, welders, carpenters, small scale market retailers) focusing on a method of prepayment which could help them access health care services. Two groups with a total of 714 operators were organized to prepay for health care services through a group premium, while the other two groups with a total of 702 operators were not organized to prepay through this approach. They prepaid through individual premium, each operator paying from his or her sources. Data on the four groups which lived in the same city was collected through a questionnaire and focus group discussions. Data collected was focused on health problems, health seeking behaviour and payment for health care services. Training of all the groups on prepaid health care financing based on individual based premium payment and group based premium payment was done. Groups were then free to choose which method to use in prepaying for health care. Prepayment through the two methods was then observed over a period of three years. Trends of membership attrition and retention were documented for both approaches.

RESULTS

Data collected showed that the four groups were similar in many respects. These similarities included levels of education, housing, and social services such as water supplies, health problems, family size and health seeking behaviour. At the end of a period of three years 76% of the members from the two groups who chose group premium payment were still members of the prepayment health scheme and were receiving health care. For the two groups which opted for individual premium payment only 15% of their members were still receiving health care services at the end of three years.

CONCLUSION

Group premium is a useful tool in improving accessibility to health care services in the poorer segments of the population especially the informal economy operators

The ‘Graying’ Of Group Health Insurance

We examine differential declines in private insurance by income and age. We show that older, higher-income people in working families are more likely to retain private coverage as premiums rise, and we project these effects on future coverage rates. The analysis suggests that trends are leading to the "graying" of the employment-based health insurance system, where older, higher-income people get private health insurance, and others increasingly have public coverage or go without. These changes raise questions about the private health care system's ability to pool health risks. Population aging could interact with rising premiums and place additional pressure on an already strained employment-based health insurance system.

Declining subscriptions to the Maliando Mutual Health Organisation in Guinea-Conakry (West Africa): what is going wrong?

Mutual Health Organisations (MHOs) are a type of community health insurance scheme that are being developed and promoted in sub-Saharan Africa. In 1998, an MHO was organised in a rural district of Guinea to improve access to quality health care. Households paid an annual insurance fee of about US$2 per individual. Contributions were voluntary. The benefit package included free access to all first line health care services (except for a small co-payment), free paediatric care, free emergency surgical care and free obstetric care at the district hospital. Also included were part of the cost of emergency transport to the hospital. In 1998, the MHO covered 8% of the target population, but, by 1999, the subscription rate had dropped to about 6%. In March 2000, focus groups were held with members and non-members of the scheme to find out why subscription rates were so low. The research indicated that a failure to understand the scheme does not explain these low rates. On the contrary, the great majority of research subjects, members and non-members alike, acquired a very accurate understanding of the concepts and principles underlying health insurance. They value the system's re-distributive effects, which goes beyond household, next of kin or village. The participants accurately point out the sharp differences that exist between traditional financial mechanisms and the principle of health insurance, as well as the advantages and disadvantages of both. The ease with which risk-pooling is accepted as a financial mechanism which addresses specific needs demonstrates that it is not, per se, necessary to build health insurance schemes on existing or traditional systems of mutual aid. The majority of the participants consider the individual premium of 2 US dollars to be fair. There is, however, a problem of affordability for many poor and/or large families who cannot raise enough money to pay the subscription for all household members in one go. However, the main reason for the lack of interest in the scheme, is the poor quality of care offered to members of the MHO at the health centre.

Alternative health insurance schemes: a welfare comparison

In this paper, we present a simple model of health insurance with asymmetric information, where we compare two alternative ways of organizing the insurance market. Either as a competitive insurance market, where some risks remain uninsured, or as a compulsory scheme, where however, the level of reimbursement of loss is to be determined by majority decision. In a simple welfare comparison, the compulsory scheme may in certain environments yield a solution which is inferior to that obtained in the market. We further consider the situation where the compulsory scheme may be supplemented by voluntary competitive insurance; this situation turns out to be at least as good as either of the alternatives.

Community rating in health insurance and different benefit packages

This paper presents a model of a competitive health insurance market with two risk types and two health benefits. In the benchmark case, community rating insurers (CRIs) are only allowed to offer the basic benefit. The additional benefit is sold by risk rating insurers (RRIs). It is shown that low risk types can only be better off at the expense of high risk types if CRIs are allowed to offer the additional benefit and no additional measures are taken. However, high risk types can be made better off if CRIs must offer the additional benefit or if community rating health insurers offering the additional benefit are subsidized while those selling only the basic benefit are taxed.

Predicting response to regulatory change in the small group health insurance market: the case of association health plans and HealthMarts

Lack of health insurance continues to be a concern for many people, even among those who are employed, and employees of small firms are much less likely to be insured than employees of larger firms. For several years, the U.S. Congress has considered legislation that would establish two new vehicles for offering health insurance coverage to small employers: association health plans (AHPs) and HealthMarts. In this paper, we present a model for estimating the impact the new entities would have on coverage and premiums in the small group health insurance market. The model produces a range of estimates based on assumptions, among others, about demand for insurance among small firms and their willingness to switch to less expensive, less generous benefit plans. We estimate that approximately 4.6 million people would obtain coverage through AHPs and HealthMarts, but fewer than half a million of them would be newly insured (based on 1999 population figures). Premiums would increase slightly for firms that continued to purchase coverage in the traditional market.

Effects of "second generation" small group health insurance market reforms, 1993 to 1997

In the mid-1990s, several state legislatures enacted a "second generation" of small group health insurance reforms that required guaranteed issue of all products and prohibited the use of health as a rating factor. We use data from two large employer surveys to compare the behavior of small business in nine states that adopted these reforms between 1993 and 1997 to the behavior of small business in 11 states and the District of Columbia, where neither of these small group health insurance market reforms existed prior to 1997 (N = 8,465 in 1993; N = 12,219 in 1997). Our analyses focus on several outcomes: health insurance offer and enrollment rates in any employer plan, and in an HMO plan; turnover in offer decisions; and premiums, variability in premiums, and the rate of change in premiums. Overall, we find no effect of small group reform on any of the outcomes; the sign of the effect is not consistent across reform states, the estimates rarely attain statistical significance, and they show no consistent pattern across the outcomes within each state. Therefore, predictions of the harm these regulations might cause to the market have not come to pass. On the other hand, proponents' hopes for a solution to low coverage rates among small businesses have not materialized either.

Private sector unlikely to follow Medicare lead in providing health plan disenrollment comparisons

BACKGROUND

There have been substantial efforts to improve the measurement and reporting of comparative quality information. A three-stage effort to develop comparative voluntary disenrollment measures for private health insurance plans is described. The literature on disenrollment and how key groups might use disenrollment information is reviewed; the development of a comparative survey of disenrollment is described; reasons employers, purchasing coalitions, and plans were ultimately unwilling or unable to sponsor the survey are delineated; and implications of these findings are discussed.

DATA AND METHODS

Methods used to develop the survey included review of existing literature on disenrollment, review of extant disenrollee surveys, cognitive testing, and expert review of the survey. Informal and formal interviews were conducted to assess the feasibility of different sponsors.

RESULTS

A disenrollment survey instrument that covered areas of common interest to consumers, purchasers, and plans could be developed, but sponsors to test the collection and reporting of these data could not be recruited. This was due to four interrelated factors: technical challenges in developing appropriate samples, wide variation in resources and capabilities of purchasers and plans, the perception that the costs of the survey outweighed the benefits of comparative information on disenrollment to the different sponsors, and the absence of strong demand from purchasers, regulators, or consumers to motivate plans to collect or report comparative information on disenrollment.

IMPLICATIONS

Several major barriers must be overcome before disenrollment information can become a component of comparative health care quality measures for the privately insured.

Reduction of catastrophic health care expenditures by a community-based health insurance scheme in Gujarat, India: current experiences and challenges

OBJECTIVE

To assess the Self Employed Women's Association's Medical Insurance Fund in Gujarat in terms of insurance coverage according to income groups, protection of claimants from costs of hospitalization, time between discharge and reimbursement, and frequency of use.

METHODS

One thousand nine hundred and thirty claims submitted over six years were analysed.

FINDINGS

Two hundred and fifteen (11%) of 1927 claims were rejected. The mean household income of claimants was significantly lower than that of the general population. The percentage of households below the poverty line was similar for claimants and the general population. One thousand seven hundred and twelve (1712) claims were reimbursed: 805 (47%) fully and 907 (53%) at a mean reimbursement rate of 55.6%. Reimbursement more than halved the percentage of catastrophic hospitalizations (>10% of annual household income) and hospitalizations resulting in impoverishment. The average time between discharge and reimbursement was four months. The frequency of submission of claims was low (18.0/1000 members per year: 22-37% of the estimated frequency of hospitalization).

CONCLUSIONS

The findings have implications for community-based health insurance schemes in India and elsewhere. Such schemes can protect poor households against the uncertain risk of medical expenses. They can be implemented in areas where institutional capacity is too weak to organize nationwide risk-pooling. Such schemes can cover poor people, including people and households below the poverty line. A trade off exists between maintaining the scheme's financial viability and protecting members against catastrophic expenditures. To facilitate reimbursement, administration, particularly processing of claims, should happen near claimants. Fine-tuning the design of a scheme is an ongoing process - a system of monitoring and evaluation is vital.

Cream-skimming in deregulated social health insurance: evidence from Switzerland

Policymakers fear that health insurers when exposed to competition will engage in cream-skimming (i.e. selection of good risks) rather than trying to improve their benefit to premium ratio. This fear surfaced also when Swiss federal government proposed pro-competitive Law on social health insurance, which barely passed a popular referendum in 1994. While a risk equalization mechanism based on age, gender, and place of residence has already been created, there is a considerable interest in improving its formula. This paper shows that a dummy variable indicating an individual's death during the period of observation causes the coefficient of determination to jump from 0.039 to 0.111. More-over, simulations of the risk selection process suggest that risk equalization should be made a permanent institution rather than being limited to a life of 10 years as prescribed by present legislation. In fact, the formula in use, with all its shortcomings, can be shown to neutralize to a great extent insurer interest in cream skimming provided he takes a longer-run view.

The effect of a redistribution system for health care for the elderly on the financial performance of health insurance societies in Japan

Health care for the elderly in Japan is financed through a pool to which all insurers contribute. We analyzed insurers' financial data to evaluate this redistribution system. Cost sharing affected financial performance substantially. The current formula for cost-sharing redistributes elderly health care costs unequally and should be changed.

Denial of health insurance due to preexisting conditions: how well does one high-risk pool work?

This study assesses whether Minnesota's high-risk insurance pool is successful at insuring those denied health insurance coverage because of preexisting medical conditions. Eight hundred and twenty-nine individuals who had been denied health insurance coverage were interviewed. At the time of the survey, 80 percent of the sample had obtained coverage, 22 percent through the state's high-risk insurance pool. Seventeen percent remained uninsured. Logistic regression was used to identify correlates of remaining uninsured. Younger age and less education were significantly associated with being uninsured versus enrolling in the high-risk pool. Younger age, less education, unemployment, being non-White, and having worse mental health were significantly associated with being uninsured versus having non-high-risk pool insurance. Despite the presence of a large high-risk pool in Minnesota, specific groups are identified as being at risk for remaining uninsured after being denied health insurance.

The structure and experience of state risk pools: 1988-1994

State risk pools are state-sponsored plans for persons who want to buy health insurance but are medically uninsurable or unable to find policies at reasonable cost. This article reviews the structure of all pools and describes in more detail the experiences of eight pools. Although pools grew in number and size in the late 1980s, most pools subsequently stabilized in size. The eight risk pools studied had high enrollee turnover; and a small proportion of enrollees accounted for a large proportion of expenditures. All pools experienced losses, and the current methods of financing losses embody undesirable incentives. Continued use or expansion of these pools may require broader methods of covering losses.

Rehabbing Medicare. Is managed care a cure-all or just a crutch?

Money, or the prospect of saving it, is what's rallying many in Congress around supporting managed care as Medicare's magic bullet. And financial, as well as community, incentives are certainly helping to push Medicare managed care programs forward in the delivery system. But will those programs accomplish everything their advocates expect?

Small businesses' changing views on health reform

Our national sample of 750 randomly chosen firms with fewer than 50 employees reveals surprising findings about the traditional views of small business on health care reform. A substantial segment of the small business community is sympathetic to health care reform, including such controversial measures as mandating that all employers contribute to the coverage of their workers, limits on health care spending, and altering the tax treatment of employer contributions for health insurance. Without premium savings, fewer than half of small businesses support the concept of health insurance purchasing cooperatives. With premium savings, a majority support it.

On taking chances with the law of large numbers

An increasing number of major purchasers of health services now consider capitation to be the preferred method of payment for individual physicians and small group practices. This paper is a primer on capitation payment plans for small risk pools. It describes some of the basic economic issues that purchasers and providers face when negotiating small-panel capitation contracts, including sources of risk, techniques of risk reduction and risk sharing. An empirical section analyses the experience of a plan that took a chance with the law (law of large numbers) and lost.
