Drug and medical cost effects of a drug formulary change with therapeutic interchange for statin drugs in a multistate managed Medicaid organization.

OBJECTIVE: Therapeutic interchange (TI) interventions are commonly used to manage pharmacy benefit costs. While several studies have considered the effect that TI interventions have on drug costs, most have not considered the effect they have on medical management costs. The purpose of the present study was to assess drug cost and drug therapy management costs of a TI intervention following a change in the drug formulary for 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor (statin) drugs, including the conversion of atorvastatin from formulary to nonformulary status. METHODS: A retrospective, quasi-experimental within-subjects design was used in this study. Administrative claims data were obtained from a select northeastern segment of a multistate Medicaid managed care organization (MCO). To be included in the study, patients had to meet the following criteria: (1) they must have had a minimum of 3 atorvastatin prescriptions during a 6-month enrollment phase, (2) they must have been continuously enrolled throughout the 900-day study period, and (3) they must have switched from atorvastatin to another statin between April 1, 2003, and July 31, 2003. The day of the switch from atorvastatin marked for each patient the end of the 12-month pre-TI period and the beginning of the 12-month post-TI period. Two separate dependent variables were developed: (1) statin drug costs (statin cost + dispensing fee) and (2) the costs paid by the MCO for the medical management of statin therapy, including office visit costs and the medical laboratory costs of measuring lipids and creatine kinase, and of checking liver functions. To estimate expenditures over 24 months, a panel analytic technique was used that allows each patient to serve as his or her own control. Multivariate models were used to assess the effects of the TI policy while controlling for age, gender, adjunctive dyslipidemia therapy, comorbidity, presence of a prior coronary artery event, statin compliance, cardiologist management, and disease severity. RESULTS: Of the 3,636 patients who met the study inclusion criteria and were converted from atorvastatin to an alternate statin drug, 129 patients (3.5%) switched back to atorvastatin following the TI. The average statin cost per claim in the 12-month post-TI period was Dollars 70.93, 9.5% less than the average cost in the 12-month pre-TI period (Dollars 78.40). The average cost per patient per year (PPPY) for statin laboratory tests (lipid panels, creatine kinase tests, and liver function tests) increased by 31.5% to Dollars 16.15 in the post-TI period compared with Dollars 12.28 PPPY in the pre-TI period, and medical office visit costs increased by 44.9% to Dollars 20.70 PPPY in the post-TI period compared with Dollars 14.29 PPPY in the preperiod. These increased costs related to the medical management of statin therapy were overwhelmed by an 11.7% reduction in statin drug costs, from Dollars 793.69 PPPY in the pre-TI period to Dollars 701.01 PPPY in the post-TI period, resulting in a net 10.0% reduction for combined statin costs and related medical costs, from Dollars 820.27 PPPY in the pre-TI period to Dollars 737.87 in the post-TI period. After limiting the analysis to patients who did not convert from atorvastatin to pravastatin (which cost more than atorvastatin before the rebate) and controlling for the influence of potential confounders, statin expenditure decreased by 33% (P < 0.001). Multivariate models indicated no statistically significant differences in the costs related to the medical management of statin therapy after the TI compared with before the TI.

Cost-effectiveness of almotriptan and rizatriptan in the treatment of acute migraine.

BACKGROUND: Migraine is a common disorder that costs US employers billions of dollars each year in missed workdays and reduced productivity. Seven triptans, including almotriptan and rizatriptan, are recommended as first-line therapy for acute migraine. OBJECTIVE: The aim of this study was to assess the relative cost-effectiveness of almotriptan and rizatriptan in the treatment of acute migraine. METHODS: A model was built to compare almotriptan 12.5 mg and rizatriptan 10 mg for the treatment of a single, acute migraine attack. Cost-effectiveness (in year-1999 US dollars) was evaluated from the perspective of a US health care payer. Mean and incremental cost-effectiveness ratios (CERs) were calculated. The effectiveness measure was the proportion of patients who achieved sustained freedom from pain with no adverse events (SNAE). Data on sustained pain-free outcomes and adverse-event rates were obtained from a meta-analysis of oral triptan trials. Efficacy and tolerability were assumed to be independent in the base-case scenario, so the total direct cost of treating a single migraine attack was calculated, adding drug costs to health service costs per attack. RESULTS: In the base-case analysis, the mean CERs for almotriptan 12.5 mg and rizatriptan 10 mg were 91.12 dollars and 131.26 dollars, respectively, per attack at which SNAE was achieved after treatment. The incremental CER for almotriptan (compared with rizatriptan 10 mg) was 6.94 dollars per additional SNAE achieved. The economic benefit of almotriptan 12.5 mg was robust in a range of sensitivity analyses. CONCLUSION: Almotriptan 12.5 mg was more cost-effective than rizatriptan 10 mg for the treatment of acute migraine in this analysis based on published data.

Economic comparison of oral triptans for management of acute migraine: implications for managed care.

Sound, informed decision making regarding which drugs to include on a formulary should be based on the best available evidence of their clinical efficacy and incidence of adverse events. Comparative drug costs and clinical effectiveness should also be considered during the formulary development process. Clinical trials traditionally evaluate efficacy and adverse events independently, whereas effectiveness in real-life conditions is defined as some combination of efficacy and side effects. When evaluating similar medications, head-to-head efficacy and effectiveness studies are preferred. For oral triptans (serotonin 5-HT(1B,1D) receptor agonists), there are many placebo-controlled trials and several active trials that compare newer oral triptans with sumatriptan; however, there have been few comparisons of triptans in head-to-head trials. Meta-analysis is an appropriate method to evaluate multiple clinical trials critically and combine the results. A recently published meta-analysis used patient-level data to assess efficacy and adverse events across multiple triptan clinical trials. In this analysis, we combined those results with medication costs to assess the overall value among oral triptans. Using this combined approach, almotriptan was found to have the greatest economic value. It delivers comparable efficacy, placebo-like tolerability, and the highest value when compared with other triptans currently marketed in the United States.

A comparison of office-based physician visits for irritable bowel syndrome and for migraine and asthma.

Three years of data from the National Ambulatory Medical Care Survey were analyzed to assess resource utilization for patients with irritable bowel syndrome (IBS), asthma, and migraine. Adjusted for prevalence, IBS-related physician visits occurred at approximately the same rate as those for asthma and 2.6 times the rate of visits for migraine. Specialist consultations for IBS were of similar frequency to those for migraine and more frequent than those for asthma. Diagnostic and screening tests were ordered more often during IBS-related visits than during migraine- or asthma-related visits. Prescription rates were similar for all three conditions. In terms of resource consumption, this chronic disorder places a burden on patients that is comparable with that of such costly conditions as asthma and migraine.

The impact of angiotensin-converting enzyme inhibitors on managed care: economic, clinical, and humanistic outcomes.

This article examines evidence of the improved clinical, economic, and humanistic outcomes associated with the use of angiotensin-converting enzyme inhibitors (ACEIs) in clinical practice, in particular in the areas of hypertension, diabetic nephropathies, post-myocardial infarction, and congestive heart failure. Pharmacodynamic and pharmacokinetic differences may exist among this class, however, these may not be clinically relevant when the drugs are given in equivalent doses. Although additional studies are necessary before a class effect can be assumed for each of these outcomes, it is important for clinicians to consider all of these outcomes when using ACEIs.

ASHP survey of ambulatory care responsibilities of pharmacists in integrated health systems--1997.

The results of a national survey of the ambulatory care functions of pharmacists in integrated health systems, including managed care organizations, are reported. Persons responsible for ambulatory care pharmaceutical services in 392 integrated health systems nationwide were interviewed by telephone and asked about their systems' organizational characteristics, information systems, pharmacist functions, and performance measures. Respondents reported a range of health-system components, including acute care hospitals, home health services, managed care products, and ambulatory care centers. Approximately 27% of respondents reported that their health system had an electronic medical records system, and 23% reported having one for ambulatory patients. Approximately 49% of respondents indicated that their system had an interdisciplinary care team for ambulatory patients that included a pharmacist. Overall, distributive functions consumed the largest portion (45%) of pharmacists' time, followed by clinical (30%) and administrative (21%) activities. The percentages of time spent on the different functions varied by geographic region and type of health system. Tracking adverse drug reactions, monitoring medication compliance, using pharmacoeconomic data for formulary decision-making, conducting medication management programs, and patient counseling were routinely provided as part of ambulatory care pharmaceutical services by 75% or more of health systems. Financial performance and patient satisfaction were the most frequently used performance-evaluation measures. Overall, pharmacists providing ambulatory care services in integrated health systems spent about 45% of their time on distributive, 30% on clinical, and 21% on administrative functions.

An economic model for a novel viral influenza diagnostic.

The authors present a model that tests the economic value of a new diagnostic test that can identify type A and B influenza. Compared with traditional treatment without trying to objectively differentiate viral from bacterial infection, substantial cost savings may be achieved if diagnostic testing is appropriately utilized in a comprehensive influenza management program.

ASHP national survey of pharmacy practice in acute care settings--1996.

The results of the 1996 ASHP national survey of pharmaceutical services in nonfederal community hospitals are presented and compared with the findings of the 1994 ASHP survey. A questionnaire was mailed to pharmacy directors at hospitals randomly sampled from those registered by the American Hospital Association. A total of 713 usable surveys were returned, for a net response rate of 37.1%. Inpatient pharmaceutical services were provided an average of 17.4 hours per weekday and ambulatory care pharmaceutical services 13.3 hours per weekday. Pharmacy directors were more likely to have duties beyond the department than in 1994 (24% versus 12%). The percentage reporting a patient-focused-care model increased from 18% in 1994 to 33% in 1996. The percentage reporting some automation of drug distribution increased from 55% in 1994 to 65% in 1996. Provision of ambulatory care pharmaceutical services was indicated by 63% of respondents, and 35% indicated providing home infusion services. Compared with 1994, pharmacy departments provided more clinical services to inpatients. The most commonly offered clinical pharmacy services for inpatients were drug-food interaction screening, drug-use evaluations, adverse-drug-reaction programs, and medication error management programs. The percentage providing pharmaceutical care to some extent increased from 44% to 60%. The percentage reporting that pharmacists had the authority to initiate or modify medication orders increased from 35% to 56%. A well-controlled formulary system was in place at 60% of hospitals, while 39% reported restrictions on prescribing. Nearly three fourths of respondents reported a therapeutic interchange policy. Mean inventory cost per patient day was $4.67, a decrease from $5.62 in 1994. About 68% of inpatient pharmacy expenditures went for drugs and fluids, 27% for staff, and 5% for other noncapital expenditures. The 1996 ASHP survey revealed continued growth in various activities related to patient care, such as implementation of patient-focused care, enhanced clinical services, and therapy management programs. Although the provision of pharmaceutical care increased, ample room for growth remains.

Overview of pharmacoeconomics and pharmaceutical outcomes evaluations.

The principles, methods, and applications of pharmacoeconomics and pharmaceutical outcomes evaluations are discussed. Pharmacoeconomics may be defined as balancing the cost with the consequences (outcomes) of pharmaceutical therapies and services. As a type of outcomes evaluation, pharmacoeconomics looks beyond just the direct or acquisition cost of a pharmaceutical by including its impact on total health resource utilization and costs. Outcomes research attempts to answer the question, What difference does the pharmaceutical make in patient outcomes under real-world conditions? The economic, clinical, and humanistic outcomes (ECHO) model for a pharmacoeconomic evaluation views the drug as some combination of its clinical, economic, and humanistic attributes. Safety and effectiveness are no longer the only salient attributes of a drug; the effect on total health resource utilization, cost, and quality of life must also be evaluated. The four types of pharmacoeconomic methods are cost-minimization analysis, cost-benefit analysis, cost-effectiveness analysis, and cost-utility analysis. As disease state management continues to emerge as a cost-management, quality assurance strategy, formularies per se will wane in importance and pharmacoeconomic and outcomes data will increase in relevance as health professionals endeavor to find the most efficient and effective combinations of medical care. Pharmacoeconomics as a component of outcomes research will help pharmacists decide which clinical circumstances, patient characteristics, and practice settings are most suitable for particular interventions.

Multivariate analysis of health status scores: chronic airway disorders and the MOS SF-36.

Multivariate analysis of variance (MANOVA) with follow-up canonical discriminant analysis may be used to interpret differences in health-related quality of life measured by the Medical Outcome Study Short Form 36 (MOS SF-36). Due to the moderate correlations between the 8 health dimensions of the SF-36, MANOVA is theoretically a more appropriate method than traditional univariate approaches for detecting group differences on the SF-36. Additionally, canonical discriminant analysis presents a novel approach to understanding the relationship between health dimensions of the SF-36 and model-independent variables. Results from the MANOVA and canonical discriminant analysis provide evidence of the sensitivity of the SF-36 in cross-sectional, self-reported data. Significant differences in health status (alpha less than or equal to 0.05) were found for the variables of age, and primary physician visits, and between levels of disease severity, type of breathing problem, whether patients had seen a specialist or not, use of emergency room, the comorbid states of depression and arthritis, and income. No significant differences in health status were reported between males and females or racial groups.

Influence of asthma or allergies on the utilization of health care resources and quality of life of college students.

The objectives of this study were to describe the treatment regimens of college students with asthma or allergies, to determine how asthma or allergies affect the lives of college students, and to evaluate the health care resources utilized by college students with asthma or allergies. A mail survey was sent to 275 students who received treatment for asthma or allergies at the Thomson Student Health Center at The University of South Carolina (TSHC-USC) during the fall 1991 semester. This survey, consisting of 46 questions, covered three key areas: current asthma or allergy management, class and work days missed, and utilization of health care resources. Students with "asthma and allergy" missed on average 2.4 days of class during the fall semester, whereas those with "asthma only" and "allergy only" missed on average 0.8 day and 1.5 days of class, respectively. Students with "allergy only" appeared to have a greater interference in their daily class and academic activities than students with "asthma and allergy" and "asthma only." In conclusion, students reported interference in their college activities and reported missing days of work and school because of asthma or allergies. This study also showed that a majority of these college students have not received asthma or allergy patient education nor utilized appropriate asthma or allergy management skills.

Economic impact of cost-containment strategies in third party programmes in the US (part I).

The rising cost of healthcare has strained the resources of governments, private third parties and individuals with responsibility to pay for it. Various strategies have been used in an attempt to control costs. This article examines the economic impact of 4 such strategies: (a) cost sharing; (b) prescription limits; (c) rebates; and (d) cost limits. Cost sharing has been successful at reducing utilisation of prescription drugs, although the effects have not been uniform across therapeutic categories. However, the long term effect on cost and utilisation of other medical services, and the impact on overall health status, remain largely unknown. Some evidence suggests that utilisation of other services may increase. The available data regarding drug rebate programmes have been descriptive in nature. However, the designs employed in this research do not establish a direct causal relationship between rebate programmes and changes in Medicaid drug expenditure. Furthermore, still unknown is the degree of cost shifting and the effect of the rebate programme on other large public and private drug purchasers. The Maximum Allowable Cost programme led to direct savings in drug costs, but the size of these savings was variable and uncertain because of administrative costs of the programme. The Estimated Acquisition Cost programme has not resulted in significant savings.

Economic outcomes and contemporary pharmacy practice.

Health care reform will no doubt entail substantial reorganization of provider and payer systems to facilitate competition among groups or alliances of providers and payers. Pharmacists must be positioned to assume an active and significant role in the delivery of high-quality, affordable, and accessible care. To fill this role, pharmacists need to understand and use pharmacoeconomic evaluation--economic outcomes assessment for pharmaceutical products and services. To explore the value to society of pharmaceutical products and pharmacists, direct, indirect, and intangible costs must be studied. Pharmacoeconomic evaluation includes cost-benefit, cost-effectiveness, cost-minimization, and cost-utility analyses. As analytical tools, pharmacoeconomic studies can provide valuable information concerning the costs and consequences of pharmaceutical products and services. Pharmacists can play an important role in contributing to the economic efficiency of the health care system and in ensuring that economic, clinical, and humanistic dimensions are balanced in treatment decisions.

Expanding Medicaid drug formulary coverage. Effects on utilization of related services.

Effects on utilization and expenditures occurring concurrently with an expansion of coverage in the South Carolina Medicaid drug formulary were investigated. Data were collected for prescriptions, physician office visits, and outpatient and inpatient hospital visits. Data were evaluated for a cohort of 12,139 individuals who had at least one prescription claim and were continuously eligible for benefits during the two-year study. A repeated measures design was employed to control the differences between subjects. A multivariate analysis of variance was used to detect overall differences in utilization and expenditures. A priori comparisons of means were performed to detect changes in levels and rates of expenditures and utilization for each service. Increases were observed in the number of prescriptions, physician visits, and outpatient visits per person while the number of inpatient hospital admissions declined. Similarly, expenditures increased for all service areas except the inpatient hospital service. The proportion of variance explained by the formulary change was small in all service areas, but would be of practical significance because of the large number of Medicaid recipients affected. From a theoretical perspective, an association of a reduction in inpatient hospital use and expenditures following the elimination of drug formulary restrictions is particularly noteworthy. These findings support the thesis that medical care services should not be viewed in isolation but rather as a system of interrelated activities. Interventions in one portion of the system are mirrored by changes in utilization of other components. Frequently, private and public medical care programs are managed with organizationally distinct benefit budgets, which are controlled independently. In view of the results of this study, this organizational approach may lead to a suboptimal allocation of resources.

Ambulatory care centers: structure, services, and marketing techniques.

A generic definition for an ambulatory care center (ACC) is not apparent. ACCs differ in ownership, primary function, and services offered. ACCs are attempting to expand their patient base by providing nonemergency care, contracting with provider organizations (e.g., HMOs and PPOs), and using aggressive marketing techniques.
