[Analysis on oral health care utilization and expenditure of residents in Beijing].

OBJECTIVE: To analyze the dental care utilization and expenditure of residents in Beijing, and to provide some basis on the policy of oral health insurance system. METHODS: A cross-sectional survey was conducted among 1,517 subjects (urban area) and 1,878 subjects (rural area) of all age groups in Beijing selected by stratified, clustering, random sampling. The data of oral health care utilization and expenditure were collected in their home. RESULTS: The number of the people who visited a dentist in a year were low both in urban area and in rural area, but the expenditure for oral health care per visit were quite high. The value of utilization of dental care in rural residents was 1/3 of that in urban residents, while the value of expenditure in rural people was about 1/2 of that in urban people. 2.07% incomes of rural residents were used for dental care per year, the corresponding value of urban residents was 1.77%. There was significant difference on the expenditure among those with different demographic, socio-economic backgrounds. CONCLUSIONS: The expenditure for oral health care was high in Beijing, which accounted for quite a lot in average incomes per year. The burden of expenditure for dental care on rural residents was heavier than that on urban residents. The level of expenditure for dental care could provide some references for oral health insurance system in Beijing.

Actual or ideal body weight: which should be used to predict energy expenditure?

Assessing energy expenditure in obese people is problematic. Two questions arise: Can we predict energy expenditure accurately? Does actual or ideal body weight better predict energy expenditure? Two groups of obese subjects--65 hospitalized adults and 65 nonhospitalized adults--were studied. Both groups had actual body weights that were at least 30% above ideal body weights. For both groups, energy expenditure was measured by indirect calorimetry and calculated using the variables sex, actual and ideal body weight, age, and ventilatory status. All but three patients were receiving nutrition support by the enteral route (either orally or by tube) or by the parenteral route (with hypertonic dextrose, amino acid, and fat). The nonhospitalized subjects fasted during measurements of energy expenditure. Regression equations were derived to predict energy expenditure. Actual body weight better predicted energy expenditure than did ideal body weight. We conclude that actual weight should be used to predict energy expenditure in obese individuals.

Stroke mortality and proportional expenditure on selected food items in Japanese communities.

Proportional food expenditure was calculated from the 1959 National Survey of Family Income and Expenditures and 843 municipalities were trichotomized according to the relative expenditure of various food items. Sex specific standardized mortality ratio (SMR) of stroke (1969-83) was calculated for each trichotomized food expenditure subgroup and compared. Results indicated that Western style diet such as expenditure of meat, milk and egg and bread had negative association with SMR. The expenditure of meat showed a negative association with SMR in all the three rice expenditure subgroups, but that of milk and egg in the low rice expenditure subgroup only. Consumption of constituents of the traditional Japanese diet, such as rice and other cereals, certain seasonings, salted and dried fish showed a positive association with SMR. Alcoholic beverages and cakes also showed a positive association. The secular trend of declining stroke mortality was parallel to the increase in the consumption of milk, meat, fish, eggs, soybeans, oil and fats and to the decrease in rice consumption. These findings were in accordance with the generally held view in Japan that moderate intake of animal protein was protective against stroke.

Energy expenditure and body fat distribution in Mohawk children.

OBJECTIVE: Epidemiologic studies suggest that Native Americans, including the Mohawk people, have a high prevalence of obesity, diabetes, and cardiovascular risk. However, current information on alterations in related variables such as energy metabolism and body composition in Native Americans is almost exclusively limited to already obese Pima adults living in the Southwest. The aim of this study was to characterize energy metabolism and body composition in young Mohawk children (17 girls, 11 boys; aged 4 to 7 years) as compared to Caucasian children (36 girls, 34 boys; aged 4 to 7 years). Total energy expenditure was measured by doubly labeled water, postprandial resting energy expenditure by indirect calorimetry, and activity energy expenditure was derived from the difference between total and resting energy expenditure. Fat and fat free mass were estimated from bioelectrical resistance, and body fat distribution was estimated from skinfolds and circumferences. RESULTS: There were no significant effects of ethnic background or sex on body weight, height, or body mass index. Fat free mass was significantly higher in boys and fat mass was significantly higher in girls, with no effect of ethnic background. Chest skinfold thickness, the ratio of trunk skinfolds:extremity skinfolds, and the waist:hip ratio were significantly higher in Mohawk children by 2.5 mm, 0.09 units, and 0.03 units, respectively, independent of sex and fat mass. Total energy expenditure was significantly higher in Mohawk children compared to Caucasian (100 kcal/day in girls, 150 kcal/day in boys), independent of fat free mass and sex, due to a significantly higher physical activity-related energy expenditure. CONCLUSION: These data suggest that: 1) body fat is more centrally distributed in Mohawk relative to Caucasian children, and this effect is independent of sex and body fat content; 2) Mohawk children have a greater total energy expenditure than Caucasian children, independent of fat free mass, due to greater physical activity-related energy expenditure.

[Energy expenditure at rest: indirect calorimetry vs the Fick principle].

UNLABELLED: The objectives of this study ere to assess the reproducibility of the energy expenditure at rest in patients with mechanical ventilation, using the indirect calorimetry method and the Fick principle, and to verify whether both methods of measuring the energy expenditure, are interchangeable. 15 critically ill patients on mechanical ventilation were studied. Each study consisted of the determination, in duplicate, of the energy expenditure at rest, using indirect calorimetry and the Fick principle. Each patient was studied on two occasions, thus yielding a total of 30 studies. The determination of the energy expenditure at rest using indirect calorimetry was carried out using an apparatus based on the closed circuit method (Calorimet), and the Fick principle was carried out using a thermodilution catheter placed in the pulmonary artery. The reproducibility coefficient of the indirect calorimetry method was 132 kcal/day, which is equivalent to 7% of the average energy expenditure at rest. The reproducibility coefficient of the Fick method was 344 kcal/day, which is equivalent to 18% of the average energy expenditure at rest. The difference between both methods, 6 +/- 50 kcal/day, was not significant. The corresponding limits in both methods were between-306 kcal/day and 294 kcal/day, which is equivalent to 15% of the average energy expenditure at rest. CONCLUSIONS: The determination of the energy expenditure at rest using the Fick method, has a worse reproducibility coefficient that obtained by indirect calorimetry, but from a clinical point of view, both methods are interchangeable.

Managed care, hospice use, site of death, and medical expenditures in the last year of life.

BACKGROUND: We examined deaths of Medicare beneficiaries in Massachusetts and California to evaluate the effect of managed care on the use of hospice and site of death and to determine how hospice affects the expenditures for the last year of life. METHODS: Medicare data for beneficiaries in Massachusetts (n = 37 933) and California (n = 27 685) who died in 1996 were merged with each state's death certificate files to determine site and cause of death. Expenditure data were Health Care Financing Administration payments and were divided into 30-day periods from the date of death back 12 months. RESULTS: In Massachusetts, only 7% of decedents were enrolled in managed care organizations (MCOs); in California, 28%. More than 60% of hospice users had cancer. Hospice use was much lower in Massachusetts than in California (12% vs 18%). In both states, decedents enrolled in MCOs used hospice care much more than those enrolled in fee-for-service plans (17% vs 11% in Massachusetts and 25% vs 15% in California). This pattern persisted for those with cancer and younger (aged 65-74 years) decedents. Decedents receiving hospice care were significantly (P<.001 for both) less likely to die in the hospital (11% vs 43% in Massachusetts and 5% vs 43% in California). Enrollment in MCOs did not affect the proportion of in-hospital deaths (those enrolled in fee-for-service plans vs MCOs: 40% vs 39% in Massachusetts; and 37% vs 34% in California). Expenditures in the last year of life were $28 588 in Massachusetts and $27 814 in California; about one third of the expenditures occurred in the last month before death. Hospital services accounted for more than 50% of all expenditures in both states, despite 77% of decedents being hospitalized in Massachusetts and just 55% being hospitalized in California. Among patients with cancer, expenditures were 13% to 20% lower for those in hospice. CONCLUSIONS: Medicare-insured decedents in California were more than 4 times more likely to be enrolled in MCOs, were 50% more likely to use a hospice, and had a 30% lower hospitalization rate than decedents in Massachusetts, yet there are few differences in out-of-hospital deaths or expenditures in the last year of life. However, patients with cancer using hospice did have significant savings.

Association of managed care market share and health expenditures for fee-for-service Medicare patients.

CONTEXT: Managed care has the potential to transform fundamentally the structure and functioning of the entire health care system, including the care provided to patients who are not enrolled in managed care plans. OBJECTIVE: To determine whether increasing health maintenance organization (HMO) market share is associated with decreased expenditures for the care of patients covered by Medicare's traditional fee-for-service plan, a group cared for well outside the boundaries of managed care. DESIGN AND SETTING: Data from the Health Care Financing Administration were used to compare expenditures for the care of Medicare fee-for-service beneficiaries for 802 market areas, representing the entire United States, for 1990 to 1994. These data were matched with data on system-wide (Medicare and non-Medicare) HMO market share in these areas. PATIENTS: All fee-for-service Medicare beneficiaries (1990-1994) except for those with end-stage renal disease. MAIN OUTCOME MEASURE: Average fee-for-service expenditure per fee-for-service Medicare beneficiary by market area. RESULTS: In a regression model, increases in system-wide HMO market share were associated with declines in both Part A and Part B fee-for-service expenditures per Medicare beneficiary (P<.001). Increases from 10% market share to 20% market share were associated with 2.0% decreases in Part A fee-for-service expenditures and 1.5% decreases in Part B fee-for-service expenditures. CONCLUSIONS: Managed care can have widespread effects on the health care system. Health care for individuals who are not covered by managed care organizations can be influenced by the presence of managed care. Lower expenditures in areas with high HMO market shares may indicate that traditional Medicare beneficiaries in areas with high market shares received fewer or less intensive services than traditional Medicare beneficiaries in other areas.

Medical care expenditures and earnings losses of persons with arthritis and other rheumatic conditions in the United States in 1997: total and incremental estimates.

OBJECTIVE: To provide estimates of the total medical care expenditures and earnings losses associated with arthritis and other rheumatic conditions (AORC), as well as the increment in such costs specifically attributable to these conditions, in the US in 1997. METHODS: The estimates were derived from the 1997 Medical Expenditures Panel Survey (MEPS), a national probability sample of 14,147 households including 34,551 persons, of whom 4,776 self-reported arthritis. After weighting, those who self-reported AORC represent 38.4 million persons. We tabulated all medical care expenditures of the adult MEPS respondents, stratified by arthritis and comorbidity status, and then used regression techniques to estimate the increment in health care expenditures attributable to AORC, after taking comorbidity, demographic characteristics, and insurance status into account. Using the same methods, we also estimated the magnitude of the earnings losses sustained by persons of working ages (18-64 years) who had AORC. RESULTS: Persons with AORC incurred mean total medical care expenditures of 4,865 dollars (total 186.9 billion dollars). The largest components of these expenditures were inpatient care (39%), ambulatory care (29%), and prescriptions (14%). The mean increment in medical care expenditures specifically attributable to AORC among those ages 18 years and older was 1,391 dollars(total approximately 51.1 billion dollars). Persons with AORC ages 18-64 years earned 3,812 dollars less on average than did other persons of these ages (total 82.4 billion dollars). Of this average, 1,579 dollars was attributable to the AORC (total 35.1 billion dollars). CONCLUSION: In 1997, persons with AORC incurred direct and indirect costs of 269.3 billion dollars, of which 86.2 billion dollars was attributable to these conditions.

Time to include time to death? The future of health care expenditure predictions.

Government projections of future health care expenditures--a great concern given the aging baby-boom generation--are based on econometric regressions that control explicitly for age but do not control for end-of-life expenditures. Because expenditures increase dramatically on average at the end of life, predictions of future cost distributions based on regressions that omit time to death as an explanatory variable will be biased upward (or, more explicitly, the coefficients on age will be biased upward) if technology or other social factors continue to prolong life. Although health care expenditure predictions for a current sample will not be biased, predictions for future cohorts with greater longevity will be biased upwards, and the magnitude of the bias will increase as the expected longevity increases. We explore the empirical implications of incorporating time to death in longitudinal models of health expenditures for the purpose of predicting future expenditures. Predictions from a simple model that excludes time to death and uses current life tables are 9% higher than from an expanded model controlling for time to death. The bias increases to 15% when using projected life tables for 2020. The predicted differences between the models are sufficient to justify reassessment of the value of inclusion of time to death in models for predicting health care expenditures.

Health care expenditure in the Nordic countries.

International comparisons of health care expenditure are associated with many different kinds of problems. One type of problem is due to heterogenous definitions and to difficulties with conversion to common prices. Such problems are present also if one selects homogeneous countries as, for example, the Nordic countries, which have a similar GDP per capita and social system. In this paper we compare the health care expenditure in the Nordic countries to illustrate the significance of these problems in international comparisons. We also correct the latest available OECD statistics for local nursing homes, which are not included in health care expenditure for Denmark but are included for the other Nordic countries, and also for the care of the mentally retarded, which is not included in health care expenditure for Denmark or, after 1985, for Sweden. In addition, comparisons of health care expenditure are presented with different currency conversion factors. The comparisons show, for example, that Sweden has a higher expenditure share of gross domestic product (GDP) than Denmark, even after corrections have been made, but that the difference between the countries becomes considerably smaller, from 37% higher expenditure for Sweden without correction to 12-15% after correction.

Life expectancy and health care expenditures: a new calculation for Germany using the costs of dying.

Some people believe that the impact of population ageing on future health care expenditures will be quite moderate due to the high costs of dying. If not age per se but proximity to death determines the bulk of expenditures, a shift in the mortality risk to higher ages will not affect lifetime health care expenditures as death occurs only once in every life. We attempt to take this effect into account when we calculate the demographic impact on health care expenditures in Germany. From a Swiss data set, we derive age-expenditure profiles for both genders, separately for persons in their last 4 years of life and for survivors, which we apply to the projections of the age structure and mortality rates for the German population between 2002 and 2050 as published by the Statistische Bundesamt. In the extreme case, we assume that morbidity is compressed at the end of life in such a way that a 60-year old in 2050 is as healthy as a 56-year old today if his life expectancy is 4 years higher. We calculate that at constant prices, per-capita health expenditures of Social Health Insurance would rise from 2596 Euro in 2002 to between 2959 Euro and 3102 Euro in 2050 when only the age structure of the population changes and everything else remains constant at the present level, and to between 5232 Euro and 5485 Euro with a technology-driven exogenous cost increase of 1% per annum. A "naïve" projection based only on the age distribution of health care expenditures, but not distinguishing between survivors and decedents, yields values of 3217 Euro and 5688 Euro for 2050, respectively. Thus, the error of excluding the "costs of dying" effect is small compared with the error of underestimating the financial consequences of expanding medical technology.

Impact of a generic substitution reform on patients' and society's expenditure for pharmaceuticals.

Sweden's pharmaceutical expenditure has increased during the last decades. On 1 October 2002 mandatory generic substitution was introduced in Sweden with the purpose to reduce the growth in pharmaceutical expenditure. The aim of the present study was to investigate if the implementation of generic substitution was associated with changes in patients' expenses and reimbursed cost for prescribed pharmaceuticals included in the Swedish Pharmaceutical Benefits Scheme (PBS). Monthly pharmacy sales data was obtained from the National Corporation of Swedish Pharmacies (Apoteket AB). The study period ranged between 1 January 2000 and 31 December 2004. Changes in pharmaceutical expenditure associated with the introduction of generic substitution were analysed with a linear segmented regression. The study comprised outpatient prescription pharmaceuticals encompassed by PBS for Sweden in total and each county council. Two different data sets were analysed. The first comprised all prescribed pharmaceuticals. The second contained only pharmaceuticals on regular prescriptions (i.e. exclusion of multidose dispensed drugs). Changes in patient co-payment per 1000 inhabitants and working day and subsidised cost per 1000 inhabitants and working day associated with the introduction of generic substitution were analysed. Expenditure was expressed in Swedish krona, SEK (SEK 1=US$ 0.14/euro 0.11, 7 July 2006). The Swedish Consumer Price Index was used to inflation-adjust expenditures with 2004 as base. The introduction of generic substitution was associated with a significant change in slope for patient co-payment in both all prescribed pharmaceuticals and pharmaceuticals on regular prescriptions (p<0.005) for Sweden in total. The slope shifted direction from a slight increase before the reform into a decline after the reform was implemented. This was also found for the average slope of patient co-payment for all county councils (p<0.0001). The introduction of generic substitution was associated with a statistically significant shift in slope for subsidised cost for Sweden in total (p<0.001). The slope shifted from a monthly increase before October 2002 to a monthly decline for all prescribed pharmaceuticals afterwards. Similar results were found for the average slope of subsidised cost for all county councils both for all prescribed pharmaceuticals and pharmaceuticals on regular prescriptions (p<0.0001). The introduction of generic substitution was associated with a shift in trend from an increase into a decrease both for patients' and society's expenditures. This suggests that generic substitution has contributed to a reduction in the growth of pharmaceutical expenditure.

Examining structural breaks and growth rates in international health expenditures.

Over the last decade, there has been a growing interest in examining health expenditures. In this paper, we study the behaviour of health expenditures in the G3 countries (USA, the UK, and Japan) and three European countries (the UK, Switzerland and Spain) over the period 1960-2000 from a different perspective, in that we examine: (1) whether there is a common structural break in health expenditures across the G3 and European countries; (2) whether structural breaks have slowed down health expenditure growth rates in these countries or vice versa. Our main findings are that: (1) health expenditures share a common break in both bivariate and trivariate cases, and structural breaks and break intervals suggest that either one or a combination of events (second oil price shock, the 1987 stock market crash and/or recessions) have contributed to the commonality of break in health expenditures in the G3, while the oil price shocks have been instrumental in the commonality of breaks for the European countries; (2) except for the UK, structural breaks have slowed down growth rates in health expenditures for the USA, Japan, Switzerland and Spain.

Household income and health care expenditures in Mexico.

The purpose of this paper is to examine the determinants of household health expenditures in Mexico. Our analysis involves the estimation of household monetary health care expenditures, using the economic and demographic characteristics of the household as covariates. We pay particular attention to the impact of household income on health expenditures, estimating the elasticity of health care expenditures with respect to income for different income groups and according to health insurance status. For the empirical analysis, we use the Mexican National Survey of Income and Expenditures of 1989. Our principle findings show that monetary health expenditures by Mexican households are sensitive to changes in household income levels and that the group which is most responsive to changes in income levels in the lower-income uninsured group. This suggests that in times of economic crisis, these households reduce cash expenditures on health care by proportionately more than higher-income and insured households.

Deductibles and health care expenditures: empirical estimates of price sensitivity based on administrative data.

OBJECTIVE: To estimate the price sensitivity of demand for health care by analysing the relation between deductibles and expenditures found in an administrative database. DATA: Data are from 100,048 privately insured in the Netherlands. Information is available on expenditures in 1996, demographic variables, deductibles, and both diagnoses from hospitalisations and pharmacy costs for the years 1993-1995. The data are unique because prior pharmacy costs are good predictors of future expenditures while in the three years concerned these costs were covered by a separate national, mandatory insurance scheme. Therefore, these costs are not affected by deductibles and can be seen as excellent proxies for health status, which this study uses to correct for the existing adverse selection with respect to the choice of deductible. METHODS: For the group of insured without deductibles an expenditure model is estimated which is subsequently used to estimate expected expenditures for insurance policies with various levels of deductible. From the difference between actual and expected expenditures the impact of deductibles on expenditures is estimated, and from this price sensitivity. RESULTS: The principal finding is an estimated price elasticity of -0.14. The highest price sensitivity is found for GP care (-0.40) and physiotherapy (-0.32), and the lowest for specialist care (-0.12) and prescription drugs (-0.08); hospital care was hardly affected.

Out-of-pocket health expenditure and debt in poor households: evidence from Cambodia.

OBJECTIVES: To document how out-of-pocket health expenditure can lead to debt in a poor rural area in Cambodia. METHODS: After a dengue epidemic, 72 households with a dengue patient were interviewed to document health-seeking behaviour, out-of-pocket expenditure, and how they financed such expenditure. One year later, a follow-up visit investigated how the 26 households with an initial debt had coped with it. RESULTS: The amount of out-of-pocket health expenditure depended mostly on where households sought care. Those who had used exclusively private providers paid on average US dollars 103; those who combined private and public providers paid US dollars 32, and those who used only the public hospital US dollars 8. The households used a combination of savings, selling consumables, selling assets and borrowing money to finance this expenditure. One year later, most families with initial debts had been unable to settle these debts, and continued to pay high interest rates (range between 2.5 and 15% per month). Several households had to sell their land. CONCLUSIONS: In Cambodia, even relatively modest out-of-pocket health expenditure frequently causes indebtedness and can lead to poverty. A credible and accessible public health system is needed to prevent catastrophic health expenditure, and to allow for other strategies, such as safety nets for the poor, to be fully effective.

Trends in expenditures for Medicare liver transplant recipients.

Liver transplantation, a resource-intensive medical procedure, is under particular scrutiny in the current era of cost containment. There have been significant changes in treatment protocols over the past decade; however, information is limited on how these changes have affected the economics of liver transplantation. This study examines a time series from 1993 to 1999 in Medicare expenditures for liver transplantation. We estimated total first- and second-year expenditures, as well as expenditures 90 days pretransplantation. These expenditures included inpatient, outpatient, physician, home health, and hospice care; immunosuppression expenditures were not estimated. Average first-year expenditures (in year 2000 dollars) for liver transplantation, excluding immunosuppressives, decreased from 201,677 dollars in 1993 to 143,363 dollars in 1998. Inpatient costs accounted for the majority of total expenditures, decreasing from 179,306 dollars in 1993 to 120,445 dollars in 1998. Total days of hospitalization decreased from 56.7 days in 1993 to 42.2 days in 1998. The majority of hospitalization occurred during the first 90 days posttransplantation, but decreased from 44.4 days in 1993 to 29.4 days in 1999. Substantial cost reductions over this period were a result of reduced hospitalization and occurred while survival rates gradually improved.

Household health expenditures in Nepal: implications for health care financing reform.

His Majesty's Government of Nepal has embarked on an ambitious social welfare programme of increasing the accessibility of primary education and health care services in rural communities. The implications on the financing of health care services are substantial, as the number of health posts has increased twelve-fold from 1992 to 1996, from 200 to 2597. To strengthen health care financing, government policy-makers are considering a number of financing strategies that are likely to have a substantial impact on household health care expenditures. However, more needs to be known about the role of households in the current structure of the health economy before the government designs and implements policies that affect household welfare. This paper uses the Nepal Living Standards Survey, a rich, nationally-representative sample of households from 1996, to investigate level and distribution of household out-of-pocket health expenditures. Utilization and expenditures for different types of providers are presented by urban/rural status and by socioeconomic status. In addition, the sources of health sector funds are analyzed by contrasting household out-of-pocket expenditures with expenditures by the government and donors. The results indicate that households spend about 5.5% of total household expenditures on health care and that households account for 74% of the total level of funds used to finance the health economy. In addition, rural households are found to spend more on health care than urban households, after controlling for income status. Distributing health care expenditures by type of care utilized indicates that the wealthy, as well as the poor, rely heavily on services provided by the public sector. The results of this analysis are used to discuss the feasibility of implementing alternative health care financing policies.
