Effect of the tobacco price support program on cigarette consumption in the United States: an updated model. (25/526)

OBJECTIVES: This study evaluated the direct effect of the tobacco price support program on domestic cigarette consumption. METHODS: We developed an economic model of demand and supply of US tobacco to estimate how much the price support program increases the price of tobacco. We calculated the resultant increase in cigarette prices from the change in the tobacco price and the quantity of domestic tobacco contained in US cigarettes. We then assessed the reduction in cigarette consumption attributable to the price support program by applying the estimated increase in the cigarette price to assumed price elasticities of demand for cigarettes. RESULTS: We estimated that the tobacco price support program increased the price of tobacco leaf by $0.36 per pound. This higher tobacco price translates to a $0.01 increase in the price of a pack of cigarettes and an estimated 0.21% reduction in cigarette consumption. CONCLUSION: Because the tobacco price support program increases the price of cigarettes minimally, its potential health benefit is likely to be small. The adverse political effect of the tobacco program might substantially outweigh the potential direct benefit of the program on cigarette consumption.  (+info)

Effect of multiple-source entry on price competition after patent expiration in the pharmaceutical industry. (26/526)

OBJECTIVE: To analyze the effect of multiple-source drug entry on price competition after patent expiration in the pharmaceutical industry. DATA SOURCES: Originators and their multiple-source drugs selected from the 35 chemical entities whose patents expired from 1984 through 1987. Data were obtained from various primary and secondary sources for the patents' expiration dates, sales volume and units sold, and characteristics of drugs in the sample markets. STUDY DESIGN: The study was designed to determine significant factors using the study model developed under the assumption that the off-patented market is an imperfectly segmented market. PRINCIPAL FINDINGS: After patent expiration, the originators' prices continued to increase, while the price of multiple-source drugs decreased significantly over time. By the fourth year after patent expiration, originators' sales had decreased 12 percent in dollars and 30 percent in quantity. Multiple-source drugs increased their sales twofold in dollars and threefold in quantity, and possessed about one-fourth (in dollars) and half (in quantity) of the total market three years after entry. CONCLUSION: After patent expiration, multiple-source drugs compete largely with other multiple-source drugs in the price-sensitive sector, but indirectly with the originator in the price-insensitive sector. Originators have first-mover advantages, and therefore have a market that is less price sensitive after multiple-source drugs enter. On the other hand, multiple-source drugs target the price-sensitive sector, using their lower-priced drugs. This trend may indicate that the off-patented market is imperfectly segmented between the price-sensitive and insensitive sector. Consumers as a whole can gain from the entry of multiple-source drugs because the average price of the market continually declines after patent expiration.  (+info)

An analysis of hospital productivity and product change. (27/526)

We developed a model to measure the contribution of changes in length-of-stay, service intensity, and productivity to the unusually low rate of growth in hospital costs per discharge in recent years. From 1992 through 1996 declining length-of-stay explained 97 percent of the decrease in real costs per discharge. Much of the drop was probably caused by care shifted from inpatient to postacute settings. Although complete data for our model are unavailable beyond that point, we cite several "leading indicators" that suggest that length-of-stay declines have played a smaller role in the continued low cost growth of 1997 and 1998 and that productivity may have risen sharply.  (+info)

The effect of selective contracting on hospital costs and revenues. (28/526)

OBJECTIVE: To examine the effects of selective contracting on California hospital costs and revenues over the 1983-1997 period. DATA SOURCES/STUDY SETTING: Annual disclosure data and discharge data sets for 421 California general acute care hospitals from 1980 to 1997. ANALYSIS: Using measures of competition developed from patient-level discharge data, and financial and utilization measures from the disclosure data, we estimated a fixed effect multivariate regression model of hospital costs and revenues. FINDINGS: We found that hospitals in more competitive areas had a substantially lower rate of increase in both costs and revenues over this extended period of time. For-profit hospitals lowered their costs and revenues after selective contracting was initiated relative to the cost and revenue levels of not-for-profit hospitals. The Medicare PPS has also led high-cost hospitals to lower their costs. CONCLUSIONS: The more competitive the hospital's market, the greater degree to which it has had to lower the rate of increase in costs. A similar pattern exists with regard to hospital revenues. Both of these trends appear to result from the growth of selective contracting. It remains unclear to what extent these cost reductions were the result of increased efficiency or of reduced quality. Since hospital cost growth is sensitive to the competitiveness of its market, antitrust enforcement is a critical element in any cost containment policy.  (+info)

Screening for hypercholesterolaemia versus case finding for familial hypercholesterolaemia: a systematic review and cost-effectiveness analysis. (30/526)

BACKGROUND: In the majority of people with familial hypercholesterolaemia (FH) the disorder is caused by a mutation of the low-density lipoprotein receptor gene that impairs its proper function, resulting in very high levels of plasma cholesterol. Such levels result in early and severe atherosclerosis, and hence substantial excess mortality from coronary heart disease. Most people with FH are undiagnosed or only diagnosed after their first coronary event, but early detection and treatment with hydroxymethylglutaryl-coenzyme (HMG CoA) reductase inhibitors (statins) can reduce morbidity and mortality. The prevalence of FH in the UK population is estimated to be 1 in 500, which means that approximately 110,000 people are affected. OBJECTIVES: To evaluate whether screening for FH is appropriate. To determine which system of screening is most acceptable and cost-effective. To assess the deleterious psychosocial effects of genetic and clinical screening for an asymptomatic treatable inherited condition. To assess whether the risks of screening outweigh potential benefits. METHODS: DATA SOURCES: Relevant papers were identified through a search of the electronic databases. Additional papers referenced in the search material were identified and collected. Known researchers in the field were contacted and asked to supply information on unpublished or ongoing studies. INCLUSION/EXCLUSION CRITERIA: SCREENING AND TREATMENT: The review included studies of the mortality and morbidity associated with FH, the effectiveness and cost of treatment (ignoring pre-statin therapies in adults), and of the effectiveness or cost of possible screening strategies for FH. PSYCHOSOCIAL EFFECTS OF SCREENING: The search for papers on the psychological and social effects of screening for a treatable inherited condition was limited to the last 5 years because recent developments in genetic testing have changed the nature and implications of such screening tests. Papers focusing on genetic testing for FH and breast cancer were included. Papers relating to the risk of coronary heart disease with similarly modifiable outcome (non-FH) were also included. DATA EXTRACTION AND ASSESSMENT OF VALIDITY: A data assessment tool was designed to assess the quality and validity of the papers which reported primary data for the social and psychological effects of screening. Available guidelines for systematically reviewing papers concentrated on quantitative methods, and were of limited relevance. An algorithm was developed which could be used for both the qualitative and quantitative literature. MODELLING METHODS: A model was constructed to investigate the relative cost and effectiveness of various forms of population screening (universal or opportunistic) and case-finding screening (screening relatives of known FH cases). All strategies involved a two-stage process: first, identifying those people with cholesterol levels sufficiently elevated to be compatible with a diagnosis of FH, and then either making the diagnosis based on clinical signs and a family history of coronary disease or carrying out genetic tests. Cost-effectiveness has been measured in terms of incremental cost per year of life gained. RESULTS: MODELLING COST-EFFECTIVENESS: FH is a life-threatening condition with a long presymptomatic state. Diagnostic tests are reasonably reliable and acceptable, and treatment with statins substantially improves prognosis. Therefore, it is appropriate to consider systematic screening for this condition. Case finding amongst relatives of FH cases was the most cost-effective strategy, and universal systematic screening the least cost-effective. However, when targeted at young people (16 year olds) universal screening was also cost-effective. Screening patients admitted to hospital with premature myocardial infarction was also relatively cost-effective. Screening is least cost-effective in men aged over 35 years, because the gains in life expectancy are small. (ABSTRACT TRUNCA  (+info)

Costs and cost-effectiveness of a church-based intervention to promote mammography screening. (31/526)

OBJECTIVES: To evaluate the costs of implementing a church-based, telephone-counseling program for increasing mammography use, and to identify the components of costs and the likely cost-effectiveness in hypothetical communities with varying characteristics. DATA SOURCES/STUDY SETTING: An ethnically and socioeconomically diverse sample of 1,443 women recruited from 45 churches participating in the Los Angeles Mammography Promotion (LAMP) program were followed from 1995 to 1997. STUDY DESIGN: Churches were stratified into blocks and randomized into three intervention arms-telephone counseling, mail counseling, and control. We surveyed participants before and after the intervention to collect data on mammography use and demographic characteristics. DATA COLLECTION/EXTRACTION METHODS: We used call records, activity reports, and interviews to collect data on the time and materials needed to organize and carry out the intervention. We constructed a standard model of costs and cost-effectiveness based on these data and the Year One results of the LAMP program. PRINCIPAL FINDINGS: The cost in materials and overhead to the church site was $10.89 per participant and $188 per additional screening. However, when the estimated cost for church volunteers' time was included, the cost of the intervention increased substantially. CONCLUSIONS: A church-based program to promote the use of mammography would be feasible for many churches with the use of volunteer labor and resources.  (+info)

Uninsured status and out-of-pocket costs at midlife. (32/526)

OBJECTIVE: To investigate how baseline health insurance coverage affects subsequent out-of-pocket costs and utilization of health services over a two-year period. DATA SOURCE: The first two waves of the Health and Retirement Study, a nationally representative survey of the noninstitutionalized population, ages 51 to 61 at baseline. Interviews were conducted in 1992 and 1994. Our sample consisted of 7,018 respondents who did not report public insurance as their sole source of coverage at baseline. STUDY DESIGN: We compared self-reports of physician visits, hospitalizations, and out-of-pocket health care costs, measured as payments to physicians, hospitals, and nursing homes, by type of insurance coverage at the beginning of the period. We estimated multivariate models of costs and service use to control for individual health, demographic, and economic characteristics and employed instrumental variable techniques to account for the endogeneity of insurance coverage. PRINCIPAL FINDINGS: Controlling for personal characteristics and accounting for the endogeneity of insurance coverage, persons at midlife with job-related health benefits went on to spend only about $50 per year less in out-of-pocket payments for health services than persons who lacked health insurance at the beginning of the period. However, they spent about $650 more per year in insurance premiums than the uninsured. The uninsured used relatively few health services, except when they were seriously ill, in which case they were likely to acquire public insurance. CONCLUSIONS: The medically uninsured appear to avoid substantial out-of-pocket health care costs by using relatively few health services when they are not seriously ill, and then relying upon health care safety nets when they experience medical problems. These results suggest that the main impact of non-insurance at midlife is not to place the locus of responsibility for costly health care upon individuals. Instead, it discourages routine care and transfers the costs of care for severe health events to other payers. Our findings on the high cost of employment-based coverage are consistent with evidence that the proportion of workers accepting health benefits from employers has been declining in recent years.  (+info)
