Decomposing pharmaceutical cost growth in different types of health plans.

OBJECTIVE: To decompose pharmaceutical spending growth into price and quantity components and to compare growth across different types of health plans. STUDY DESIGN: Retrospective analysis of pharmaceutical claims for active employees of a large national employer from 1996 to 1998, who were enrolled in traditional fee-for-service plans, health maintenance organizations (HMOs), and preferred provider organizations. OUTCOME MEASURES: Outcomes measures included total cost growth, price growth, and quantity growth. Quantity growth was divided into growth in use of existing products and in use of newly introduced products. For existing products, quantity growth was further decomposed into growth in the number of prescriptions and change in the mix of prescriptions. RESULTS: During the study period, HMOs had the greatest cost growth. This differential cost growth was largely attributable to changes in utilization as opposed to changes in prices, which were similar among types of health plans. Introduction of new products contributed 15 to 20 percentage points to cost growth in each setting. Differences in cost growth were largely attributed to differences in the growth rate of spending on existing products. For existing products, the impact of increases in the number of prescriptions was much greater in the HMOs, while the impact of changes in the mix of prescriptions was only mildly greater in the HMOs. CONCLUSIONS: Pharmaceutical cost growth was largely attributable to changes in utilization as opposed to changes in prices. Changes in utilization patterns were complex and differed across types of health plans.

Pharmacoeconomic modeling of prior-authorization intervention for COX-2 specific inhibitors in a 3-tier copay plan.

OBJECTIVE: To determine from a health plan perspective the cost-effectiveness of cyclooxygenase-2 (COX-2) specific inhibitors, with and without a prior-authorization (PA) process. METHODS: A modeling exercise was employed, based on prescription drug claims for a managed care organization with 3.8 million health maintenance organization (HMO) and preferred provider organization (PPO) members. Drug claims revealed 96154 members (2.9% of the 3.3 million members with a pharmacy benefit) who received either one or more prescriptions for a COX-2 drug or a nonspecific nonsteroidal anti-inflammatory drug (NSAID). These patients were stratified into 2 groups for further analysis, those having a concurrent proton pump inhibitor (PPI) and those without a concurrent PPI. Decision analysis was used to estimate the cost-effectiveness of COX-2 therapy. Actual health plan drug claims data were used to determine utilization and prescribing patterns of nonspecific NSAIDs, COX-2 specific inhibitors, and PPIs. Results from the literature from 8 clinical trials were employed to determine the probability of a serious gastrointestinal (GI) event. Cost-effectiveness analysis (CEA) was used to determine the cost of each therapy, including the predicted cost to treat a serious GI event in a drug benefit design with PA versus a benefit design without PA. RESULTS: Cost-effectiveness analysis (CEA) showed that the cost per success no serious GI event) for Cox-2 specific inhibitors with PA was US dollars 278 versus US dollars 422 without PA. CONCLUSIONS: The one-year model predicted that costs associated with an increase in COX-2 utilization after removal of PA would exceed the costs to administer PA and treat NSAID-related serious GI events in the managed care population. Based upon this CEA, PA appears to be an effective tool to manage COX-2 pharmacy costs. Further examination of the medical claims would be useful to validate the assumed GI event rates with or without PA and to further demonstrate more definitively the value of a PA program for COX-2 drugs.

Guidelines for physician contracting with alternative delivery systems.

The rapid proliferation of alternative healthcare delivery systems--particularly health maintenance organizations (HMOs) and preferred provider organizations (PPOs)--means that physicians contemplating participation in one of these entities must obtain, at the least, information about the group's ability to operate efficiently and effectively. For physicians who are contracting directly with a specific HMO, PPO, or independent practice association (IPA), issues that are relevant in all situations include termination, submission of data, discipline procedures, no solicitation covenants, arbitration clauses, rights to discontinue treatment, use of consultants, compliance with state and federal laws, and exclusivity.

Costs and price competition in California hospitals, 1980-1990.

Critics of health care reform proposals that incorporate managed competition contend that it has never been broadly implemented. However, insurance plans that combine insurance with the provision of care have been widely implemented and have been tested most extensively in California. This DataWatch explores California's experience with health maintenance organizations (HMOs) and preferred provider organizations (PPOs), the introduction of which was followed by overall reductions in hospital costs. These reductions were larger in competitive markets. If implemented on a national scale, such selective contracting could be expected to reduce the growth of hospital costs even more rapidly than occurred in California.

Managed care discounting: evidence from the MarketScan database.

The paper examines price discounting by health maintenance organizations (HMOs) and preferred provider organizations (PPOs) in markets for hospital services. Our empirical analysis focuses on transaction prices for angioplasty, which is a relatively common procedure with well-defined "product" characteristics. After controlling for patient and procedure heterogeneity and market power, we find that on average angioplasty prices are 8% lower for PPOs than for fee-for-service plans, followed by point-of-service HMOs, which capture a 24% discount. Our results are in general agreement with earlier work by Cutler, McClellan, and Newhouse (2000), who show that managed care discounts are "real," after accounting for case severity and process of care.

Price competition and hospital cost growth in the United States (1989-1994).

In recent years, most health care markets in the United States (US) have experienced rapid penetration by health maintenance organizations (HMOs) and preferred provider organizations (PPOs). During this same period, the US has also experienced slowing health care costs. Using a national database, we demonstrate that HMOs and PPOs have significantly restrained cost growth among hospitals located in competitive hospital markets, but not so in the case of hospitals located in relatively concentrated markets. In relative terms, we estimate that HMOs have contained cost growth more effectively than PPOs.

HMO and PPO growth and hospital utilization and payment: a recursive model.

A recursive model of growth of Blue Cross and Blue Shield Plan Health Maintenance Organization (HMO) and Preferred Provider Organization (PPO) membership share is used to analyze total hospital utilization and payments per thousand insured members over an eight year study period, 1980 through 1987. Results indicate a strong, significant relationship between previous year Plan payments and current year growth in HMO membership share. Additional results suggest that Blue Cross and Blue Shield Plans experienced significant reductions in utilization and payments rates resulting from PPO membership share gains and not from HMO membership share gains.

Managed care involvement by cardiovascular specialists: prevalence, attitudes and influence on practice.

OBJECTIVES: The purpose of this study was to determine the involvement in and attitudes toward managed care by cardiovascular specialists and the influence of such programs on their practices. BACKGROUND: No in-depth study has measured the impact of managed care on cardiovascular specialists. Therefore, we conducted a mail survey to determine the prevalence of managed care arrangements among cardiovascular specialists and variations among pediatric and adult cardiologists and cardiovascular surgeons; the types of managed care arrangements in which cardiovascular specialists are engaged; the reasons why those not participating in managed care have chosen not to do so; and the general attitudes among cardiovascular specialists with regard to various aspects of managed care. In addition, we evaluated the impact of managed care among several aspects of cardiovascular practice. METHODS: A questionnaire was mailed in the spring of 1993 to 4,577 practicing, domestic, American College of Cardiology (ACC) members selected at random from within each primary cardiovascular specialty group (adult cardiologists, pediatric cardiologists and cardiovascular surgeons). Additional data concerning practice characteristics were cross tabulated using results from the 1992 ACC membership profile survey. RESULTS: In total, 1,961 of the 4,577 members responded to the survey, representing a 43% response rate. Of all survey respondents, 76% reported entering into at least one relationship with a health maintenance organization (HMO) or preferred provider organization (PPO). Of those not participating in managed care arrangements, the most frequently mentioned reason was "concern over the quality of care." This reason was cited by 51% of those not entering into HMO relationships and 41% of those not participating in PPOs. The majority of respondents indicated that they do not strongly object to the gatekeeper approach to managing nonemergent patients, although more than half indicated concern that gatekeepers may not be appropriate in the management of cardiac emergencies. In addition, cardiovascular specialists report that under managed care, referrals have not increased, income has decreased, and managed care formularies have not substantially affected their ability to prescribe appropriate medication to their patients. CONCLUSIONS: Despite concerns over the quality of care and contract requirements and general philosophical opposition of cardiovascular specialists, most are becoming integrated into managed care environments.

Managed care: the second generation.

The current status of managed health care is described and its impact on hospital and pharmacy operations is summarized. In the 1980s, managed care evolved into a three-segment industry, comprising health maintenance organizations (HMOs), preferred-provider organizations, and fee-for-service plans. Five new trends are emerging as managed care, now an established part of the country's health-care delivery system, enters its second generation: dual- and triple-option plans with financial risk sharing between employers and insurers/HMOs, point-of-service determination of benefits and coverage, consolidation of the number of options offered by employee health plans, creation of exclusive provider organizations, and direct provider contracting. Persons charged with negotiating managed-care contracts will make use of three primary cost-management methods: benefit design, provider reimbursement, and prospective pricing. Employees will take an increasingly active part in purchase decisions. Enrollees will face tradeoffs between their desire for maximum freedom of choice of provider and higher premiums, deductibles, and out-of-pocket expenses. Managed-care plans will continue to have a strong impact on hospitals, especially in the areas of reimbursement and use review. The effect of managed care on pharmacy operations will vary from institution to institution; among the positive results may be increased appreciation of the role of clinical pharmacy services in reducing the incidence of readmissions and the length of hospital stays. The result of these changes in the structure of health-care benefits will be greater price sensitivity, marked by a suppression of unnecessary use of health-care services and an increased tendency to compare and evaluate health-plan costs.

Managed care in the United States: promises, evidence to date and future directions.

In the United States, health maintenance organizations (HMOs) and preferred provider organizations (PPOs) have proliferated during the past decade. To a great extent, their growth has been based on the perceived promise of these organizations to reduce health care costs without compromising quality of care and introduce a level of competition into the health care market that would result in a more efficient and effective health care system. This paper examines the promise of managed care as delivered through HMOs and PPOs, the evidence to date on the extent to which their promise has been met, and recent developments in the organization of managed care systems.

Health effects of managed care among the near-elderly.

OBJECTIVE: The authors evaluate whether enrolling in a health maintenance organization (HMO) or preferred provider organization (PPO) affects the health of adults ages 55 to 64, relative to fee-for-service plans. METHODS: A nationwide random sample of 4,044 adults with employer-sponsored health insurance is drawn from the 1994 to 2000 waves of the Health and Retirement Study. Multinomial logit regressions are estimated for self-reported general health status, first using a sample of all near-elders, then using subsamples of near-elders with and without longstanding chronic health conditions. The possibility of selection bias into managed care plans is considered and explicitly addressed in model estimation. RESULTS: We find no ill effects of HMOs on health status, and older adults with a history of chronic health conditions actually fare better upon enrolling in these plans. DISCUSSION: More research is needed to understand the reasons for the observed beneficial effects of managed care.

Private health insurance for adolescents: is it adequate?

PURPOSE: To examine the nature and extent of private insurance coverage available for health services needed by six hypothetical adolescents with physical and mental health conditions. METHODS: Health insurance information was obtained from the most commonly sold product of the largest health maintenance organization (HMO) and preferred provider organization (PPO) in each state and the District of Columbia. Contract documents were collected in 1999 and were in effect at the end of 1998. Our response rate was 97% and included 49 HMOs and 49 PPOs. The extent of coverage was analyzed according to benefit availability, structure, limits, and protections, as well as condition and treatment restrictions. RESULTS: The two hypothetical adolescents with asthma and depression had coverage for their recommended health services in most of the 98 plans. However, the four hypothetical adolescents whose conditions included pregnancy and sexually transmitted disease, anorexia nervosa, injury, and substance abuse and bipolar disorder would rarely have access to coverage for all of their recommended services. Ancillary and behavioral health therapies were least likely to be available in the amounts considered necessary by medical experts. All of the hypothetical adolescents would be more likely to obtain coverage for certain services in HMO than in PPO plans. CONCLUSIONS: Despite the obvious value of the private health insurance system, insurance benefits are not always matched to the needs of the adolescent. Employers and policymakers may want to consider financial or other incentives to create more uniformity in employer-based coverage, particularly for preventive care, prescription drugs, and reproductive services; greater availability of mental health and substance abuse benefits; and new mechanisms to support access to confidential care.

Strategic implications of healthcare reform for mental health providers.

While most of the recent national attention on healthcare reform has focused on physicians, acute-care hospitals, and the insurance industry, what about mental healthcare providers? Where do psychiatric hospitals, psychiatrists, psychologists, and other mental healthcare professionals fit into the healthcare payment system of the future? For example, if the United States ends up with what is called universal access--a payment source for all Americans--will it include mental health benefits? The stakes are high; one quarter of the American population either has no health insurance or is covered by Medicaid. Many current reform proposals include tort reform; but how would it affect mental healthcare providers? Will managed care--primarily health maintenance organizations (HMOs) and preferred provider organizations (PPOs)--be a part of the reshaping of the United States healthcare system? This article has three objectives: To summarize the various healthcare reform proposals and provide a description of the key elements anticipated in the most likely reform package. To consider the strategic implications of payment reform for the mental healthcare industry. To identify strategies for mental healthcare providers that are likely to be useful regardless of the shape of healthcare reform.

Health-insurance products and plan options.

Trends in health insurance are discussed, with emphasis on insurers' efforts to offer an array of cost-effective plans tailored to the needs of employers and subscribers. Health-insurance companies, responding to employers' demands to curtail the rising costs of premiums, now offer a variety of insurance products. While indemnity plans, health maintenance organizations (HMOs), and preferred-provider organizations (PPOs) remain as the three basic types of plans, insurers are combining these elements in different ways, creating dual- and triple-option plans that consist of indemnity insurance and an HMO, a PPO and an HMO, or other variations. Insurers offering multiple options may effect internal cost savings through shared personnel and administrative expenses. Four factors influence the development and marketing of insurance products: cost and volume of healthcare services, adverse selection, competition, and the profit incentive. Many of the insurance products have been developed in response to requests for maximum freedom of choice of provider; as an example, the fastest-growing HMO product in 1989 was the point-of-service HMO, which allows the subscriber to seek care from a provider who is not part of the HMO network. PPOs and exclusive-provider organizations (EPOs) are growing; these are often organized by hospitals or physician networks. Among the new trends in product-line development are "riders" for specialty services such as vision care and prescription drugs. As competition intensifies, marketing efforts are focusing on previously overlooked groups such as the small employer and certain ethnic communities. Cost and freedom of choice will remain important criteria in the selection of insurance products.(ABSTRACT TRUNCATED AT 250 WORDS)

Finance issue brief: any willing provider.

Today, almost half the states have laws obligating managed care organizations (MCOs) such as health maintenance organizations (HMOs) and preferred provider organizations (PPOs) to contract with any willing health care provider. Although most provisions are limited to pharmacies or pharmacists, several states have adopted broad provisions applying to hospitals, physicians, chiropractors, pharmacists, podiatrists, therapists and nurses.

Evaluation of audit-based performance measures for dental care plans.

OBJECTIVES: Although a set of clinical performance measures, i.e., a report card for dental plans, has been designed for use with administrative data, most plans do not have administrative data systems containing the data needed to calculate the measures. Therefore, we evaluated the use of a set of proxy clinical performance measures calculated from data obtained through chart audits. METHODS: Chart audits were conducted in seven dental programs--three public health clinics, two dental health maintenance organizations (DHMO), and two preferred provider organizations (PPO). In all instances audits were completed by clinical staff who had been trained using telephone consultation and a self-instructional audit manual. The performance measures were calculated for the seven programs, audit reliability was assessed in four programs, and for one program the audit-based proxy measures were compared to the measures calculated using administrative data. RESULTS: The audit-based measures were sensitive to known differences in program performance. The chart audit procedures yielded reasonably reliable data. However, missing data in patient charts rendered the calculation of some measures problematic--namely, caries and periodontal disease assessment and experience. Agreement between administrative and audit-based measures was good for most, but not all, measures in one program. CONCLUSIONS: The audit-based proxy measures represent a complex but feasible approach to the calculation of performance measures for those programs lacking robust administrative data systems. However, until charts contain more complete diagnostic information (i.e., periodontal charting and diagnostic codes or reason-for-treatment codes), accurate determination of these aspects of clinical performance will be difficult.

Retrospective, long-term follow-up study of the effect of a three-tier prescription drug copayment system on pharmaceutical and other medical utilization and costs.

BACKGROUND: Previous research has suggested that 3-tier prescription drug copayment systems produce drug cost savings without affecting the use of other medical services during the first 12 months after implementation. Assessment of such systems with a longer follow-up period has been needed. OBJECTIVE: This study examined the effect of a 3-tier copayment system on pharmaceutical and medical utilization and cost for 30 months after implementation in a population of commercially insured, preferred-provider organization members. METHODS: This was a quasi-experimental, pre-post with comparison group design that gathered data retrospectively from the claims database of a preferred-provider organization in the Midwestern United States. The intervention group comprised members whose employer switched from a 2-tier (generic/brand copayment) plan to a 3-tier (generic/formulary/nonformulary) plan. The comparison group comprised members whose employer retained the 2-tier plan. Employers did not offer a choice between the 2- and 3-tier plans. Outcome measures included total drug cost; net insurer cost (drug cost minus copayment); number of prescription claims; numbers of office visits, inpatient hospitalizations, and emergency department visits; and rates of continuation with chronic medication therapy. RESULTS: Relative to the comparison group (n=4132), the intervention group (n=3577) showed reduced growth in net cost and lower utilization of third-tier (nonformulary) medications (P<0.001 and P<0.01, respectively). The intervention and comparison groups did not differ significantly with respect to numbers of office visits, emergency department visits, or inpatient hospitalizations. Medication continuation rates were lower for the intervention than the comparison group at 6 months for oral contraceptives (P<0.05), but chronic medication therapy continuation rates did not differ significantly at any other time point or for estrogens, antihypertensives, or antihyperlipidemics. CONCLUSION: In the population studied, previous research findings were confirmed over a longer time period.
