A comparison of single- and multi-payer health insurance systems and options for reform.

A major choice confronting many countries is between single-payer and multi-payer health insurance systems. This paper compares single-payer models in the areas of revenue collection, risk pooling, purchasing, and social solidarity. Single-payer and multi-payer systems each have advantages which may meet countries' priorities for their health insurance system. Single-payer systems are usually financed more progressively, and rely on existing taxation systems; they effectively distribute risks throughout one large risk pool; and they offer governments a high degree of control over the total expenditure on health. Multi-payer systems sacrifice this control for a greater ability to meet the diverse preferences of beneficiaries. Several major reforms of single-payer insurance systems--expansion of the role of private insurance and transformation to a multi-payer system--are then described and illustrated using specific country examples. These reforms have been implemented with some success in several countries but face several important challenges.

Universal New York Health Care. A single-payer strategy linking cost control and universal access.

Now that universal access to health care is back on the governmental agenda, elected officials are faced with the dilemma of expanding our present pluralistic system of numerous private and public payers, with its built-in administrative inefficiencies and inflationary pressures, or scrapping the present system of financing and moving to a tax-based scheme like the Canadian Medicare program, an option fraught with political difficulties. There is, however, a third option. The New York State Department of Health has developed a proposal for universal access--Universal New York Health Care, or UNY-Care--that would retain the existing payers, including employer-based insurance coverage, but combine them in a one-payer framework. Providers would no longer have to interact with the many public and private payers, each with its own rules, criteria, and levels of payment. The single payer would serve as the only payer for most health care services and would also negotiate reimbursement rates. The single-payer framework should bring savings in administrative and billing costs and should move government closer to the goal of buying health care services--getting good value for payment rendered--rather than simply paying bills as they are submitted. Although the single-payer strategy could be implemented at either the state or the federal level, it seems ideal as the principal responsibility of the states in a national plan for universal coverage.

Impact of the New Jersey all-payer rate-setting system: an analysis of financial ratios.

Although prospective payment may contain costs, many analysts are concerned about the unintended consequences of rate regulation. This article presents the results of a case-study analysis of the New Jersey rate-setting programs during the period 1977-1985. Using measures of profitability, liquidity, and leverage, data for New Jersey, the Northeast, and the United States as a whole are used to contrast the impact of two forms of prospective payment. After attempting alternative cost-containment methods, the New Jersey Department of Health implemented an all-payer system in which prospective rates of compensation were established for DRGs. The new rate-setting system was designed to control costs, improve access to care, maintain quality of services, ensure financial viability of efficient providers, and limit the payment differentials associated with cost shifting. The results of this study have a number of implications for the evaluation of all-payer rate regulation. First, although the New Jersey all-payer system was more successful than the partial-payer program in restraining the rate of increase in cost per case, savings were achieved without adversely affecting the viability of regulated hospitals. Second, the large differentials among payers that were associated with the partial-payer program were reduced dramatically by the all-payer program. Third, using the financial position of inner-city hospitals relative to suburban hospitals as a measure of equity, the all-payer system appeared to be a fairer method of regulating rates.

Factors influencing third party payer costs for allogeneic BMT.

To assess how payer costs for allogeneic BMT relate to patient characteristics and clinical complications, a retrospective cohort study of 402 persons undergoing allogeneic BMT between 1980 and 1987 at a university-based BMT center was designed to determine total inpatient payer costs, including hospital and physician costs, and number of days hospitalized during the first 180 days following BMT. The average total inpatient payer cost (in 1990 dollars) during the first 180 days following BMT was $208,410. Inflation-adjusted inpatient payer costs increased from $227,806 in 1980 to $308,545 in 1983, and then decreased to $156,163 by 1987. In multivariate analysis, inpatient payer costs were strongly associated with occurrence of CMV infection (increase of $53,517; p = 0.0001) or acute GVHD (increase of $46,500; p = 0.001), and significantly associated with malignant (versus non-malignant) disease (decrease of $36,633; p = 0.05), even after adjusting for length of survival and year of BMT. Inpatient payer costs were not related to patient age, sex or race. Despite recent reductions in inpatient payer costs for BMT, CMV infection and acute GVHD continue to be associated with tremendous costs to third party payers. Further reductions in the costs of BMT may require improved prevention of CMV infection and GVHD.

The effect of payer type on orthopaedic practice expenses.

BACKGROUND: Orthopaedic practice expenses are the costs associated with providing treatment that are incurred by a physician's practice. Certain payer types are thought to increase orthopaedic practice expenses by increasing paperwork and other administrative activities. Our study investigated the hypothesis that orthopaedic practice expenses would vary significantly by payer type. METHODS: With use of the method of activity-based costing, data on the orthopaedic practice expenses for 518 consecutive patients (286 men and 232 women) who had a sports-related knee condition were collected. For each patient enrolled in the study, all employees recorded the actual amount of time that they spent on each of seventeen specific activities previously shown to be associated with orthopaedic practice. The seventeen activities were categorized as either a value-added activity, which adds value to the services provided to the patient, or a nonvalue-added activity, which does not add value. The total orthopaedic practice expense was the sum of the value-added and nonvalue-added activity expenses. To capture all practice expenses associated with a particular episode of care, data collection continued until the patient was discharged and the financial account had been settled. We evaluated the differences in orthopaedic practice expenses among six payer types: self-pay, indemnity plan, Medicare, health maintenance organization/point-of-service plan (HMO/POS), preferred provider organization (PPO), and Workers' Compensation. RESULTS: The differences among payer types with respect to orthopaedic practice expenses were significant (p = 0.0000000004). The total orthopaedic practice expense per episode of care was $123 for self-pay, $195 for an indemnity plan, $148 for Medicare, $178 for PPO, $208 for HMO/POS, and $299 for Workers' Compensation. These differences among payer types persisted even after accounting for patient age, gender, treatment type (nonoperative versus operative), and number of office visits. Nonvalue-added activity expenses differed to a greater degree among the payer types than did value-added activity expenses. CONCLUSIONS: The payer type was found to be an important factor affecting orthopaedic practice expenses, particularly with respect to nonvalue-added activity expenses.

Payer cost savings with endometrial ablation therapy.

CONTEXT: Dysfunctional uterine bleeding (DUB) is a significant cost burden for payers in the US healthcare system because hysterectomy, the common curative treatment, is associated with high hospitalization costs. OBJECTIVE: To determine the potential economic benefit to payers of endometrial ablation as an alternate treatment for the benign DUB disorder. STUDY DESIGN: A retrospective analysis of healthcare claims including the total direct costs to the payer (reimbursement) and patient (copayment). The study was designed to capture all DUB-related claims costs for the entire episode of care from initial diagnosis through follow-up care for 12 months postprocedure. PATIENTS AND METHODS: Twenty-four months of claims data from premenopausal women aged 25 to 50 years enrolled in a large managed care organization were screened based on relevant diagnostic and procedural codes. Incidence and costs of hysterectomy and ablation were determined, and potential payer savings were calculated based on hypothetical hysterectomy-to-ablation conversion rates of 25% to 50%. RESULTS: By performing ablation in lieu of hysterectomy for DUB, an average per-case savings of approximately $4,300 is possible. Potential annual payer savings are approximately $515,000 and $1.03 million for a 1-million-member plan, based on the 25% and 50% conversion rates, respectively. The recently approved uterine balloon therapy ablation technique could be instrumental in overcoming current barriers to wider utilization of ablation surgery. CONCLUSION: If ablation is used in lieu of hysterectomy when medically appropriate, a payer organization could reduce the cost of treating patients with DUB who are not responsive to drug therapy or dilation and curettage alone. Our data suggest that hysterectomy is the most common surgical therapy for this disorder, even though the less invasive endometrial ablation approach is more consistent with accepted DUB treatment guidelines. Payers therefore have an economic incentive to adopt guidelines and reimbursement policies that promote ablation therapy for DUB.

National Provider Identifier (NPI) planning and implementation fundamentals for providers and payers.

Federal HIPAA legislation mandates that the National Provider Identifier (NPI) be fully implemented across all healthcare entities between May 2005 and May 2007, or 2008 for small payers. Starting May 2005, healthcare providers will be eligible to obtain an NPI and use these numbers to submit claims or conduct other transactions specified by HIPAA. By 2007, the NPI must be used in connection with the electronic transactions identified in HIPAA. Today, individual payers assign unique identification numbers to healthcare providers, and, in most cases, payers assign multiple identification numbers to healthcare providers and their "subparts." As a result, providers have multiple payer-specific identification numbers. The NPI is a unique, 10-digit federal healthcare provider identification number that will be used by all healthcare providers and payers and other healthcare entities involved in administrative and financial transactions associated with health service events and related activities. This article will use software and data experts' knowledge as well as the authors' NPI implementation readiness assessment work to review the impact to both payers and providers, including hospitals, clinics, and other service entities. The authors will suggest planning, budgeting, architecting, and data management solutions for payers and providers to achieve the optimal administrative simplification goals intended by the NPI, without compromising data integrity and interoperability objectives across the service spectrum of the healthcare enterprise.

Single-payer national health insurance. Physicians' views.

BACKGROUND: Forty-one million Americans have no health insurance and, despite the growth of managed care, medical costs are again increasing rapidly. One proposed solution is a single-payer health care financing system with universal coverage. Yet, physicians' views of such a system have not been well studied. METHODS: We surveyed a random sample of physicians (from the American Medical Association Masterfile) in Massachusetts, regarding their views on a single-payer health care financing system and other financing and physician work-life issues that such a system might affect. RESULTS: Of 1787 physicians, 904 (50.6%) responded to our survey. When asked which structure would provide the best care for the most people for a fixed amount of money, 63.5% of physicians chose a single-payer system; 10.7%, managed care; and 25.8%, a fee-for-service system. Only 51.9% believed that most physician colleagues would support a single-payer system. Most respondents would give up income to reduce paperwork, agree that it is government's responsibility to ensure the provision of medical care, believe that insurance firms should not play a major role in health care delivery, and would prefer to work under a salary system. CONCLUSIONS: Most physicians in Massachusetts, a state with a high managed care penetration, believe that single-payer financing of health care with universal coverage would provide the best care for the most people, compared with a managed care or fee-for-service system. Physicians' advocacy of single-payer national health insurance could catalyze a renewed push for its adoption.

Payer status, but not race, affects the cost of liver transplantation.

Prior studies evaluating the impact of race and payer on cost of liver transplantation did not adjust for clinical factors known to increase cost. We analyzed the impact of race and payer on the cost of liver transplantation after controlling for clinical factors. We analyzed data obtained on patient and graft survival, cost, race, age, sex, payer, and United Network for Organ Sharing (UNOS) status from 153 consecutive liver transplants in 130 patients performed at University of North Carolina Hospitals from September 1991 through December 1996. Race was classified as white or nonwhite, and payer status was classified as commercial or Medicare/Medicaid. Multivariate linear regression was used to compare costs, adjusting for age, sex, race, payer, and UNOS status. For the 130 patients, 1-year patient and graft survival rates were 88% and 82%, respectively. There were no significant differences in patient and graft survival or in the unadjusted average cost of liver transplantation by race or payer. After adjusting for demographic and clinical factors, the cost of transplantation was $28,494 more for Medicare/Medicaid recipients compared with the commercial insurance recipients (P = .02). The Medicare/Medicaid group had higher intensive care unit costs compared with the commercial insurance group ($17,807 and $9,359, respectively; P = .03), and a longer length of stay (41 and 31 days, respectively; P = .04). There was no significant difference in cost between whites and nonwhites adjusting for these factors. Medicare or Medicaid patients had a higher cost of transplantation compared with those with commercial insurance. The cost of liver transplantation was similar for whites and nonwhites.

Payment source and the cost of hospital care: evidence from a multiproduct cost function with multiple payers.

This study investigates the capacity of hospitals to vary the intensity of their services based on patients' expected sources of payment. While the concept of price discrimination by hospitals based on payer generosity ("cost-shifting") has been discussed extensively, the notion that hospitals can adjust payer-specific marginal costs to reflect differences in reimbursement policies has not been studied in depth. To examine this issue. this analysis employs a multiproduct cost function with hospital outputs defined as admissions by payment source, controlling for the distribution and severity of illness ("casemix") for each payer. Marginal costs of casemix-adjusted discharges are obtained and compared for Medicare, Medicaid, Private Payers, and a residual category that includes uncompensated care. We find that indeed, payer-specific marginal costs generally reflect payer generosity.

Decision-making by healthcare payers.

Healthcare payers are faced with the need to allocate finite resources to maximize population health. To assist in decision-making, healthcare payers are increasingly using health outcomes information and economic analyses. Healthcare payers are often under pressure to make early decisions (around the time of product launch), when the evidence available is imperfect. They must also consider the equitable distribution of resources between therapeutic areas. Tools to help healthcare payers reach transparent and objective decisions include cost-utility analysis and decision modelling. In practice, healthcare payers in different countries (for example, Ireland, France and Canada) vary in the approaches taken to reimbursement and formulary listing decisions. The key to decision-making among healthcare payers is the provision of appropriate evidence, comparing any new treatment approach to current best practice, in situations corresponding to real life. When data assumptions have to be made, these should be clearly stated with consideration of the impact of varying the assumptions. The impact on budgets should also be considered.

Prospects for single payer coverage after Harry and Louise.

PURPOSE OF THE STUDY: This paper considers evidence of indirect influences of the Harry and Louise media campaign on public support of single payer health coverage in a conservative state. DESIGN AND METHODS: Data from a statewide, representative public opinion survey on health reform conducted in Oklahoma over a two-year period, 1992-1994, were combined with data on the Harry and Louise media campaign broadcasts. A two-stage structural-equation model tested the hypothesis that support for single payer varied inversely with support for "mainstream" health reform. RESULTS: Findings support the hypothesis, providing evidence that a campaign affecting support for mainstream health reform inversely affects support for single payer, despite the tendency for support for health reform to correlate with support for single payer. IMPLICATIONS: Findings suggest that an unintended indirect effect of a campaign against mainstream health reform may have been increased support for single payer. Those proposing future reforms should be aware of available media technologies and how they will be used.

Payer status and the utilization of hospital resources in acute myocardial infarction: a report from the National Registry of Myocardial Infarction 2.

BACKGROUND: Prior studies have suggested that payer status may be an important determinant of medical resource utilization and outcome in acute myocardial infarction (AMI). METHODS: A national cohort of 332,221 patients with AMI enrolled from June 1994 to July 1996 were compared within 5 payer groups to ascertain the influence of payer status on hospital resource allocation for AMI in the United States. RESULTS: Medicare comprised the largest proportion (56%), followed by commercial insurance (25%), health maintenance organization (HMO) (10%), uninsured (6%), and Medicaid (3%). Compared with commercially insured patients, Medicare and Medicaid patients received fewer reperfusion therapies, underwent fewer invasive cardiac procedures, and had longer hospitalizations. After adjusting for differences in clinical characteristics, Medicare recipients were as likely as commercially insured patients to receive acute reperfusion therapies or any invasive cardiac procedure. Uninsured and HMO patients tended to utilize hospital resources with intermediate frequency. Medicare recipients aged 65 years or older and the HMO group had similar hospital mortality rates compared with the commercial group (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.96-1.20 and OR, 0.93; 95% CI, 0.83-1.04, respectively), but Medicaid and uninsured groups had higher hospital mortality rates compared with the commercial group (OR, 1.30; 95% CI, 1.14-1.48 and OR, 1.29; 95% CI, 1.12-1.48, respectively). CONCLUSION: This report suggests significant variation by payer status in the management of AMI throughout the United States, but no important differences in mortality among the 3 largest payer groups.

The association between the on-site availability of cardiac procedures and the utilization of those services for acute myocardial infarction by payer group. The National Registry of Myocardial Infarction 2 Investigators.

BACKGROUND: Prior studies have suggested that in-hospital availability may be an important determinant for the use of invasive cardiac services; however, whether this association is influenced by payer status remains unclear. HYPOTHESIS: The interaction of payer status and the on-site availability of coronary arteriography is associated with increased utilization of this procedure. METHODS: In-hospital availability and utilization of coronary arteriography was ascertained in 275,046 patients with acute myocardial infarction (AMI) enrolled in the National Registry of Myocardial Infarction 2 from June 1994 to April 1996. Logistic regression analyses were performed to determine the association between the on-site availability of cardiac catheterization at the initial hospital and subsequent utilization of coronary arteriography. Similar analyses were performed within Medicare, Medicaid, Commercial, Health Maintenance Organization (HMO), and Uninsured payer groups. RESULTS: Patients initially admitted to hospitals having on-site cardiac catheterization facilities were almost twice as likely to receive coronary arteriography as patients admitted to hospitals without such facilities and later transferred out [un-adjusted odds ratio (OR) = 1.69, 95% confidence interval (CI) 1.66-1.73, p < 0.0001; adjusted OR = 2.08, 95% CI 2.01-2.15, p < 0.0001]. Furthermore, this relationship of increased utilization with greater availability was evident within each payer group, but was highest among those with Commercial insurance and lowest among Medicaid recipients: [Commercial insurance (OR = 2.19, 95% CI 2.07-2.31, p < 0.0001); Uninsured (OR = 1.74, 95% CI 1.57-1.92, p < 0.0001); HMO (OR = 1.67, 95% CI 1.54-1.82, p < 0.0001); Medicare 1.60, 95% CI 1.55-1.64, p < 0.0001); Medicaid (1.46, 95% CI 1.29-1.65, p < 0.0001)]. CONCLUSIONS: Our results show a strong association between in-hospital availability and subsequent utilization of invasive cardiac procedures following AMI among all patients, but the strength of these associations varied among payer status.

Blood and marrow transplantation compensation: perspective in payer and provider relations.

The high cost per patient of hematopoietic cell transplantation (HCT) causes this therapy to be the focus of much controversy, given the competing societal demands to provide all possible therapy to preserve life while simultaneously limiting global health care expenditures. Treatment and eligibility decisions for HCT often are heavily scrutinized by both governmental and private payers and not simply determined by physicians, facility providers, and the patient. In an effort to control costs, payers have administrative infrastructure to review resource utilization by these patients. Additionally payers have developed payment methodologies, usually in the form of a case rate payment structure, that place facilities and physician providers of HCT at financial risk for adverse patient financial outcomes in an effort to promote optimal utilization and selection of patients for HCT. As providers enter into such financial risk arrangements with payers, the providers need to understand the true cost of care and be able to identify predictable and unpredictable outlier risks for the financial consequences of medical complications. HCT providers try to protect themselves from excessive financial risk by having different payment rates for different types of transplant, eg, autologous versus HLA or genotypically matched related versus HLA mismatched transplants. Because at certain times in the HCT process risk is more unpredictable, HCT providers require different payment system strategies for the different time periods of care such as evaluation, pre-transplant disease management, harvesting, and cell processing, as well as short- and long-term follow-up. Involvement by clinicians is essential for this process to be done well, especially given the rapid changes technological innovation brings to HCT. Constant dialogue and interaction between providers and payers on these difficult financial issues with HCT is essential to preserve patient access to this potentially lifesaving therapy.

Using health outcomes data to inform decision-making: healthcare payer perspective.

Healthcare payers are charged with the responsibility of achieving maximum profits or output within their limited budget. As the demands are always greater than the budget, there is growing interest in tools that can inform decisions on the allocation of limited resources. Healthcare payers are using health outcomes data to assist the decision-making process, although the way in which such information is being used may differ between payers. From the perspective of the French sickness fund, there is a need for real-world information to supplement the results of clinical trials and inform negotiations on pricing. In the US, the large databases of healthcare insurers are being examined in order to carry out retrospective cohort studies that go some way towards providing such real-world information on outcomes with alternative treatments. Another approach to health outcomes information has been taken by an Israeli healthcare organisation, Maccabi Healthcare Services, which introduced a disease management programme in order to improve outcomes of asthma management. Clearly, healthcare payers are using health outcomes information in a variety of ways to inform decision-making. The extensive databases available to payers may be used to good effect, to obtain real-life information that supplements clinical trial data and economic models of outcomes and costs, and to enable the targeting of interventions.

Can provider antitrust suits against payers be successful?

In today's increasingly competitive healthcare marketplace, payers, not providers, are the driving force in the healthcare delivery system. Therefore, providers are feeling greater pressure to compete on price and other terms to become recommended providers for these payers. The question becomes: what, if any, antitrust claims does a provider have who is excluded from a payer's healthcare program, receives a lower rate of payment compared to other providers in a payer's program, or is disadvantaged by a payer's pricing decision?

[Comparison of the cost of treatment of premature labor with atosiban or beta-sympathomimetics from the perspective of the health care payer--a pharmacoeconomic model].

OBJECTIVE: To evaluate the cost of treating premature delivery with atosiban or beta-sympatomimetic drugs (fenoterol and hexoprenalin) from the perspective of health care payer--the medical insurance company. DESIGN: A pharmaco-economic model based on the results of randomized, controlled clinical study. SETTING: Hospital Pharmacy at Vitkovice Hospital of Blessed Mary Antonia, Ostrava. METHODS: The study is based on the application of clinical decision-making analysis, which includes results of a randomized controlled clinical study as well as data on the cost of clinical interventions and cost of drug therapy. The pharmaco-economic model was created from the perspective of the payer of health care--the insurance company. This model presumes the administration of atosiban or beta-sympatomimetic drugs (fenoterol and hexoprenalin) for the period of 18 and 48 h and the therapy of possible untoward effects for the next 72 h after the administration of the drugs. The analysis of sensitivity of pharmacokinetic model also employs so called low and high estimate of supplementary cost for the treatment of untoward effects. RESULTS: After the administration of the drugs for the period of 18 h the total cost of the payer of medical care was in the range of 21,914.5-21,974.4 CKr in atosiban, 19,878.7-22,661.4 CKr in fenoterol and 19,942.9-21,974.4 CKr in hexoprenalin. In the administration of the drugs for 48 h, the overall cost of the payer of medical care was in the range of 43,082.5-43,142.4 CKr in atosiban, 19,960.3-23,150.7 CKr in fenoterol and 20,131.3-23,574.0 in hexoprenalin. CONCLUSIONS: This study compared overall cost associated with hospitalization of a premature delivery from the perspective of the medical care payer, i.e. the health insurance company. The authors applied a pharmaco-economic model evaluating hospitalization for the period of 48 h and subsequent therapy of possible untoward effects for the period of up to 72 h. In case of a shorter administration of atosiban (up to 18 h) the overall cost of hospitalization for premature delivery for the period of 48 h from the point of view of medical insurance company is basically comparable with the administration of beta-sympatomimetic drugs. If atosiban is administered for more than 18 h, the overall cost of hospitalization is higher than with beta-sympatomimetic drugs, and the cost increases in relation to the duration of atosiban administration.
