BACKGROUND: In South Africa, cardiovascular disease (CVD) is the leading cause of death among all population groups, other than blacks, among whom it ranks third. CVD therefore has a severe impact on the South African economy. OBJECTIVES: To ascertain the availability and quality of South African data on the cost of CVD and to estimate the impact of CVD on the South African economy during 1991. METHODS: The direct health care costs and the indirect costs related to loss of productivity were estimated. Where no direct or complete detailed South African data were available, projections were made based on reasonable assumptions of data and models developed in other countries; these were applied to the limited available South African data. The major disease outcomes considered for this cost estimation were: expenditure on ischaemic heart disease, cerebrovascular disease (stroke), venous thrombosis and embolism, and peripheral vascular diseases and related conditions. These diseases are responsible for the majority of fatal cases of CVD reported in South Africa. RESULTS: The estimated total cost of CVD in South Africa in 1991 was between R4.135 billion and R5.035 billion. This does not include the cost of rehabilitation and follow-up of CVD patients since the necessary data were not available to estimate it. About three-quarters of the direct health care costs were carried by the private sector. The direct health care costs were estimated to be approximately 42% of the total cost. The rest reflects the indirect cost of earnings foregone as a result of premature morbidity and mortality. CONCLUSION: To determine accurately the total economic burden of CVD on the South African economy, additional data will have to be collected. The estimated economic burden of CVD in South Africa clearly highlights the need for a broad-based population strategy, part of an overall national effort to prevent, diagnose and cost-effectively treat CVD. 相似文献

This article combines data from a clinical trial of donepezil with costing figures to evaluate expected direct costs of care over 5 years after diagnosis of Alzheimer's disease (AD) for patients aged 75 years and over at diagnosis. A Markov model simulates the progression of elderly persons through changing levels of severity. The model compares three treatment regimes for each of two patient groups; mild AD at start of treatment; moderate AD at start of treatment. Patients are followed until 5 years after the start of the treatment. Despite the acquisition costs, use of donepezil is approximately cost-neutral for both 5 mg and 10 mg treatment groups and for patients initially at either mild or moderate states of illness. Expected costs are slightly higher than for the placebo group, but higher expenditure on drugs is partly offset by lower costs of care consequent on treated patients not declining as rapidly as those untreated. The model showed that donepezil patients spent less time in the state of severe dementia, where costs of care are higher. Sensitivity analysis on key assumptions demonstrated that expected costs were highly dependent on discount rate and, more significantly, on the mortality rate. 相似文献

BACKGROUND: Antireflux surgery is a highly effective treatment option in patients with severe gastro-oesophageal reflux disease. However, because of the increasing pressure of cost containment within health care, cost aspects must also be added to the decision-making process. METHODS: The aim of this analysis was to assess the total cost of open antireflux surgery during the first year after operation in 178 patients with chronic reflux, who were recruited into a controlled, prospective clinical trial. The study was carried out in 17 hospitals in the Nordic countries. RESULTS: The cost of the operation represented more than 90 per cent of the direct medical costs which amounted to approximately US $5700. For a patient in the work force the indirect cost, i.e. loss of production, represented 47 per cent of the total cost, which was about US $10800. CONCLUSION: The total cost profile of open antireflux surgery has now been established prospectively and can form a basis for future comparisons. 相似文献

BACKGROUND: Studies focusing on the economic impact of cancer on families have emphasized that costs of chronic disease are substantial for patients and their families. However, little effort has been devoted to measuring the costs of care for families of patients hospitalized with stroke. METHODS: A total of 215 stroke patients and their families from four teaching hospitals in the Taipei metropolitan area were monitored from the date of the patient's admission to hospital until the date of discharge. The value of labor contributed by families was estimated by assigning the current monetary market rate of providing health aide to the time families spent caring for patients in hospital. Lost earnings of patients and families, expenditure for medical care, and expenses for food, clothes, adult diapers, transportation and other miscellaneous items were determined and summed to arrive at the total family cost of providing care. RESULTS: The average cost of care for one family per inpatient day was NT$4,358.20. A total of 98.6% of the families incurred labor costs, which accounted for about half of family costs for providing care. Hospital bills accounted for almost 19% of total family costs. The income loss for families and patients accounted for about 25% of total family costs. Expenses for food, clothes, transportation, diapers and other illness-related miscellaneous items accounted for about 12% of total family costs. Multiple regression analyses demonstrated that the number of family members involved in giving care and the length of stay are important predictors for the total cost of care. Average total family costs per day increased by 24.3% when an additional family member was involved in providing care. Total family costs increased 2.5% for each hospital day. CONCLUSIONS: If direct and indirect nonmedical costs are not included in the total cost calculation for providing hospital care to stroke patients, the economic impact of care on families is likely to be underestimated. 相似文献

CONTEXT: As the managed care environment demands lower prices and a greater focus on primary care, the high cost of teaching hospitals may adversely affect their ability to carry out academic missions. OBJECTIVE: To develop a national estimate of total inpatient hospital costs related to graduate medical education (GME). DESIGN: Using Medicare cost report data for fiscal year 1993, we developed a series of regression models to analyze the relationship between inpatient hospital costs per case and explanatory variables, such as case mix, wage levels, local market characteristics, and teaching intensity (the ratio of interns and residents to beds). SETTING AND PARTICIPANTS: A total of 4764 nonfederal, general acute care hospitals, including 1014 teaching hospitals. MAJOR OUTCOME MEASURES: Actual direct GME hospital costs and estimated indirect GME-related hospital costs based on the statistical relationship between teaching intensity and inpatient costs per case. RESULTS: In 1993, academic medical center (AMC) costs per case were 82.9% higher than those for urban nonteaching hospitals (actual cost per case, $9901 vs $5412, respectively). Non-AMC teaching hospital costs per case were 22.5% higher than those for nonteaching hospitals (actual cost per differences in case, $6630 vs $5412, respectively). After adjustment for case mix, wage levels, and direct GME costs, AMCs were 44% more expensive and other teaching hospitals were 14% more costly than nonteaching hospitals. The majority of this difference is explained by teaching intensity. Total estimated US direct and indirect GME-related costs were between $18.1 billion and $22.8 billion in 1997. These estimates include some indirect costs, not directly educational in nature, related to clinical research activities and specialized service capacity. CONCLUSIONS: The cost of teaching hospitals relative to their nonteaching counterparts justifies concern about the potential financial impact of competitive markets on academic missions. The 1997 GME-related cost estimates provide a starting point as public funding mechanisms for academic missions are debated. The efficiency of residency programs, their consistency with national health workforce needs, financial benefits provided to teaching hospitals, and ability of AMCs to maintain higher payment rates are also important considerations in determining future levels of public financial support. 相似文献

The economic cost of obesity: the French situation 总被引:1,自引:0,他引:1
OBJECTIVE: To estimate the economic burden of obesity in France. DESIGN: A prevalence-based approach identifying the costs incurred during a given year (1992) by obese subjects. MEASUREMENTS: Direct costs (personal health care, hospital care, physician services, drugs) and indirect costs (lost output as a result of cessation or reduction of productivity caused by morbidity and mortality); economic benefits due to the reduced incidence of hip fractures. RESULTS: The direct costs of obesity (BMI > or = 27) were 11.89 billion French Francs (FF), which corresponded to about 2% of the expenses of the French care system. Hypertension represented 33% of the total amount and cancer 2.5% of the direct cost of obesity. Indirect costs represented FF 0.6 billion. These are conservative estimates as far as all obesity-related diseases and all health care and indirect costs were not included due to missing information. CONCLUSION: These results were remarkably similar to previous reports on the economic costs of obesity in other western countries (USA, Sweden, Netherlands, Australia) which concluded that the cost of obesity amounted to around 2% to 5% of the total cost of health care in industrialized societies. 相似文献

Asthma is a chronic inflammatory disease characterized by reversible airway obstruction and nonspecific airway hyperreactivity. Asthma is managed in steps according to disease symptoms and severity. Treatment goals are to decrease symptoms, improve pulmonary function, and reduce overall morbidity and the associated cost of medical care. Antiasthma drugs are a key component of asthma management that are classified as either long-term-control medications that control symptoms and prevent disease exacerbations, or quick-relief medications that rapidly relieve airway obstruction and acute asthma symptoms. Several new leukotriene (LT) modulators have been developed that promise to improve asthma control, including LT receptor antagonists montelukast and zafirlukast and the 5-lipoxygenase inhibitor zileuton. Each decreases symptoms and the use of rescue medication, and improves pulmonary function in patients with mild intermittent to moderate persistent asthma. 相似文献

OBJECTIVES: To test a method of measuring the related cost of acute otitis media (AOM) and to provide a preliminary calculation of the indirect and directs costs associated with a single, medically treated episode of AOM. DESIGN: The Otitis Media Diary was used to measure indirect and direct costs associated with AOM in a prospective cohort study. Measured values included the parental time spent in otitis-specific child care and the number and type of medications used. A previously developed economic model was used to calculate the monetary costs associated with the value of caregiver time and the total opportunity cost of AOM. SETTING: The pediatric clinic of Madigan Army Medical Center, Tacoma, Wash. PATIENTS: A cohort of 25 children (12 with AOM and 13 controls) aged 1 to 3 years. MAIN OUTCOME MEASURES: Caregiver time and medication use. RESULTS: The total cost attributable to AOM in the 3-month period following diagnosis was $1330.58 (95% confidence interval, $1008.75-$1652.43), with the majority of that cost stemming from the indirect, rather than direct, costs of illness. After conservative estimates of unmeasured expenses, such as clinic visits and transportation, were accounted for, indirect costs, accrued primarily by parental time, accounted for nearly 90% (95% confidence interval, 87.1%-92.3%) of the total 3-month cost associated with AOM and its medical treatment. The cost items of the Otitis Media Diary were also highly correlated with each other and with other measures of clinical and functional health status. CONCLUSIONS: Otitis Media Diary measures of parental time and medication use appear to provide a more accurate means of calculating the real social costs attributable to the AOM disease process in this cost-effectiveness analysis. 相似文献

BACKGROUND: We performed a cost-benefit analysis of a protocol for studying patients with squamous intraepithelial lesions (SIL) on Papanicolaou smears to determine whether it compared favorably with resources spent on other health programs for screening and treatment. METHODS: During a 3-year period, 424 patients with dysplastic Papanicolaou smears were examined, studied by biopsy, and treated. We calculated costs based on a model protocol and derived a cost per year of life saved for preventing death from invasive cervical carcinoma. A sensitivity analysis was performed on selected assumptions of the analysis. RESULTS: The marginal, or incremental, cost of colposcopic evaluation and treatment of Papanicolaou smears with low-grade SIL, high-grade SIL (moderate), and high-grade SIL (severe), depending on assumptions, ranged from $406 to $5746, $160 to $2263, and $85 to $1197 per year of life saved, respectively. Depending on the assumption of the rate of Papanicolaou smears with SIL in the screened population being 1.8%, 5.1%, or 11.5%, the estimated total cost of screening and treating the referral base was $1.3 million, $538,126, and $307,037, respectively. This results in the average cost per year of life saved to screen and treat low-grade SIL, high-grade SIL (moderate), and high-grade SIL (severe) to be $1105 to $68,909, $375 to $21,673, and $177 to $8831, respectively. CONCLUSIONS: Both marginal cost and average screening costs of evaluating and treating abnormal Papanicolaou smears by the protocol described in this article compare favorably with costs per year of life saved for other health care screening and treatment strategies for many assumptions. The marginal cost to perform colposcopy on patients with a Papanicolaou smear with low-grade SIL is so low that it is relatively a very effective strategy. 相似文献

PURPOSE: Airways remodeling, evaluated as the subepithelial layer thickness, was compared in asthmatic patients with that of healthy subjects, and was related to clinical grading of disease, presence of atopy, and length of asthmatic history. SUBJECTS AND METHODS: Thirty-four patients with stable asthma (mean age+/-SD: 26.5+/-9.2 years; 10 female) treated with only inhaled beta2-agonists and eight healthy volunteers (mean age+/-SD: 24.6+/-2.5 years; four female) were recruited for the study. Twenty-seven of 34 asthmatics had atopy. Eleven patients had newly diagnosed conditions (duration of disease < or = 1 year), nine patients had long asthmatic history (> 1 year and < or = 10 years), and 14 had prolonged asthmatic history (> 10 years). Bronchial responsiveness to methacholine (M) was expressed as provocative concentration of M causing a 20% fall in FEV1 (PC20) (mg/mL). Degree of asthma severity was assessed using a 0- to 12-point score based on symptoms, bronchodilator use, and daily peak expiratory flow variability over a 3-week period. Bronchoscopy and bronchial biopsy were performed successfully for all subjects; the subepithelial layer thickness, in biopsy samples, was measured from the base of bronchial epithelium to the outer limit of reticular lamina. RESULTS: In asthmatics, baseline FEV1 values (percent of predicted) ranged from 75.7 to 137.0%, and PC20 M ranged from 0.15 to 14.4 mg/mL. According to the asthma severity score, 14 asthmatics were classified as having mild disease, 14 as having moderate disease, and six as having severe disease. The mean values of subepithelial layer thickness were 12.4+/-3.3 microm (range, 6.8 to 22.1 microm) in asthmatics, and 4.4+/-0.5 microm (range, 3.8 to 5.2 microm) in healthy subjects (p<0.001). Subepithelial layer thickness of those with severe asthma differed significantly from that of patients with moderate and mild asthma (16.7+/-3.1 microm vs 12.1+/-2.7 microm and 10.8+/-2.4 microm, p<0.01 and p<0.003, respectively). Moreover, in asthmatics, degree of thickening was positively correlated to asthma severity score (Spearman rank correlation coefficient [rs]=0.581; p<0.001), and negatively correlated with baseline FEV1 (rs=-0.553; p<0.001) and PC20 M (rs=-0.510; p<0.01). No difference was found between degree of thickening observed in atopic asthmatics, compared with that of nonatopic asthmatics, or between degree of thickening in patients with different lengths of asthmatic history. Lastly, multiple regression analysis revealed that asthma severity score was the significant predictive factor for thickness of subepithelial layer. CONCLUSIONS: We confirmed that airways remodeling is a very distinctive and characteristic pathologic finding of asthma. We also demonstrated that it is related to the clinical and functional severity of asthma, but not to atopy or length of asthmatic history. 相似文献

The abuse of alcohol causes health and social problems, such as sickness, death, injury, pain, suffering and crime. These harms impose an economic burden on society. Resources are used or foregone as a consequence of alcohol abuse. This article provides an estimate of the economic cost of alcohol abuse in Ontario in 1992. It uses the cost-of-illness method, in particular, the human-capital approach to estimate the prevalence-based economic costs of alcohol abuse. This methodology is consistent with international guidelines formulated at the 1994 International Symposium on Economic and Social Costs of Substance Abuse. The direct and indirect economic costs of alcohol abuse are identified and estimated. The total economic cost of alcohol abuse, from a societal perspective, is estimated to be US$2261.10 million in Ontario in 1992. 相似文献

OBJECTIVE: To estimate the potential direct cost of making triple combination antiretroviral therapy widely available to HIV-positive adults and children living in countries throughout the world. METHODS: For each country, antiretroviral costs were obtained by multiplying the annual cost of triple antiretroviral therapy by the estimated number of HIV-positive persons accessing therapy. Per capita antiretroviral costs were computed by dividing the antiretroviral costs by the country's total population. The potential economic burden was calculated by dividing per capita antiretroviral costs by the gross national product (GNP) per capita. All values are expressed in 1997 US dollars. RESULTS: The potential cost of making triple combination antiretroviral therapy available to HIV-positive individuals throughout the world was estimated to be over US$ 65.8 billion. By far the greatest financial burden was on sub-Saharan Africa. The highest per capita drug cost in this region would be incurred in the subregions of Southern Africa (US$ 149) followed by East Africa (US$ 116), Middle Africa (US$ 44), and West Africa (US$ 42). In the Americas, subregional data indicated the highest per capita drug cost would be in the Latin Caribbean (US$ 22), followed by the Caribbean (US$ 17), Andean Area (US$ 7), the Southern Cone (US$ 6), North America (US$ 6), and Central American Isthmus (US$ 5). In Asia and Europe the percentage of the GNP necessary to finance drug therapy was less than 1% in most countries examined. CONCLUSION: Our results demonstrate that the cost of making combination antiretroviral therapy available worldwide would be exceedingly high, especially in countries with limited financial resources. 相似文献

Exhaled NO is increased in patients with asthma and may reflect disease severity. We examined whether the level of exhaled NO is related to the degree of airway obstruction induced by direct and indirect stimuli in asthma. Therefore, we measured exhaled NO levels before and during recovery from histamine and hypertonic saline (HS) challenge (Protocol 1) or histamine, adenosine 5'-monophosphate (AMP), and isotonic saline (IS) challenge (Protocol 2) in 11 and in nine patients with mild to moderate asthma, respectively. The challenges were randomized with a 2-d interval. Exhaled NO and FEV1 were measured before and at 4, 10, 20, and 30 min after each challenge. NO was measured during a slow VC maneuver with a constant expiratory flow of (0.05 x FVC)/s against a resistance of 1 to 2 cm H2O. Baseline exhaled NO levels were not significantly different between study days in Protocol 1 (mean +/- SD: 4.8 +/- 1.8 ppb [histamine] versus 5.4 +/- 2.1 ppb [HS], p = 0.4) or in Protocol 2 (7.9 +/- 4.7 ppb [histamine], 8.3 +/- 5.2 ppb [AMP], and 7.2 +/- 3.7 ppb [IS], p = 0.7). A significant reduction in exhaled NO was observed directly after HS (mean +/- SEM: 39.2 +/- 3.9 %fall) and AMP challenge (32.3 +/- 7.3 %fall) (MANOVA, p < 0.001), respectively, whereas exhaled NO levels tended to decrease after histamine challenge. Isotonic saline challenge did not induce changes in exhaled NO (p = 0.7). There was a positive correlation between %fall in FEV1 and the %fall in exhaled NO after histamine, HS, and AMP challenge as indicated by the mean slope of the within-subject regression lines (p <= 0.04). We conclude that acute bronchoconstriction, as induced by direct and indirect stimuli, is associated with a reduction in exhaled NO levels in asthmatic subjects. This suggests that airway caliber should be taken into account when monitoring exhaled NO in asthma. 相似文献

The purpose of this study was to assess the impact of asthma Self Management Training on the health status and resource use of patients with chronic asthma. The study consisted of a randomized control design of chronic asthmatic patients in a tertiary care center in India. The intervention group (153 patients) received four training sessions in addition to the regular care provided to the control group (150 patients). Health status and resource use were measured at baseline and over a one year follow-up period. The intervention group had significantly better health status (measured by breathing ability), fewer productive days lost, and lower resource use (hospitalizations and emergency room visits) than the control group. Total annual costs (direct and indirect) were also lower, though physician costs were not included in the assessment. Therefore, incorporation of asthma Self Management Training as part of clinical management of asthma can result in improvements in health status and reductions in hospital use. 相似文献

Asthma is a condition which incurs a great cost to the National Health Service, to the economy and above all to the patient in terms of loss of quality of life. Treatments for asthma need to be evaluated for their cost-effectiveness. Traditional outcome measures, such as airflow measurements have their limitations, especially in mild to moderate asthma. Quality-of-life measurements represent the impact of asthma on the everyday lives of asthmatics across the whole disease spectrum. Disease specific quality-of-life questionnaires, such as the Asthma Quality-of-Life Questionnaire (AQLQ), provide reliable instruments in reflecting disease severity, but also in detecting changes in quality of life produced by different asthma treatments. Quality-of-life measures are becoming increasingly important and are end-points of therapeutic asthma trials in primary care, but should be used in conjunction with more surrogate markers of asthma severity such as peak flow. 相似文献

OBJECTIVE: To compare outcome and costs between laparoscopic and open hernia repair. DESIGN: Prospective randomised study. SETTING: One university and two district hospitals in Sweden. SUBJECTS: 200 men aged 25-75 years. MAIN OUTCOME MEASURES: Operating time, hospital stay, complications, and time to recovery. A cost-minimisation-analysis was used in which the total costs were calculated for a defined period of time for each option. RESULT: The one year follow-up rate was 98%. Mean (SD) operation times in the laparoscopic and open groups were 72 (30) and 62 (25) minutes, respectively (p = 0.009). Hospital stay and complication rates did not differ between the groups. Among employees the mean (SD) periods off work in the laparoscopic and open groups were 10 (8) and 23 (21) days, respectively (p = 0.0001). The mean direct costs of the laparoscopic operation were increased by SEK 4037 (US$ 483) but the savings in indirect costs resulting from earlier return to work were SEK 11392 (US$ 1364). CONCLUSIONS: Laparoscopic hernia repair gave the employed patients faster recovery and return to work, and was the most cost-effective strategy provided that both direct and indirect costs were included. 相似文献

A 2-year trial was conducted to evaluate the cost-effectiveness of heliotherapy for psoriasis. The course and cost of psoriasis of 46 Finnish patients were first closely monitored for 1 year, then the patients received a 4-week supervised heliotherapy treatment in the Canary Islands, Spain, after which they continued to be followed for another year. Heliotherapy dramatically reduced the severity of psoriasis and also seemed to have favourable long-term effects on psoriasis. The mean direct cost of the 4-week heliotherapy for one patient was FIM12,289 (1 Pound = FIM7.0 in 1989). The cost of flights and half-board in Spain formed nearly 60% (FIM7033) of the total cost. In the year preceding heliotherapy, the mean direct annual cost of antipsoriasis therapy was FIM7335 and in the year after FIM5700, a reduction of 22% in annual costs; this change was not statistically significant because there were large variations in costs among patients. The costs of heliotherapy exceeded manyfold the mean monthly cost of conventional psoriasis therapy. There were no overall savings using heliotherapy in those patients suffering mainly from moderately severe psoriasis. Heliotherapy saved costs only in those patients with severe psoriasis that required expensive medication or ward treatment. Although heliotherapy cannot be regarded as an economical treatment for the average patients with psoriasis, it clears psoriasis effectively and is preferred by patients. Thus, heliotherapy constitutes an alternative for patients suffering severe psoriasis. 相似文献

AIMS: To estimate the cost of population screening for haemochromatosis in Australia and to compare the cost of alternative screening strategies. METHODS: The costs of screening for haemochromatosis were analysed in a hypothetical study using transferrin saturation as the primary screening test, with confirmation of the diagnosis by either liver biopsy or DNA testing for the recently-described haemochromatosis gene. RESULTS: Screening, with confirmation of the diagnosis by liver biopsy, would cost between US$5079 and US$8813 per case detected (excluding administrative costs), depending on the screening strategy (Aust$ = US$0.80). If a DNA test were used instead of liver biopsy, the cost would be reduced to an estimated US$3954-US$4410 per case. This would be further reduced to US$2457 by detection of additional cases by screening family members. The least costly strategy utilised a transferrin saturation threshold of 55% and DNA testing for confirmation of the diagnosis; however, a transferrin saturation threshold of 45% increased the cost only marginally. The initial screening step (transferrin saturation) accounted for 74%-94% of the estimated cost of the screening programme. CONCLUSIONS: Screening for haemochromatosis using transferrin saturation involves relatively modest costs which may be recovered if complications of haemochromatosis can be prevented by early detection and treatment. The most cost-effective strategies utilised transferrin saturation for initial screening, followed by DNA testing. Reduction in the cost of transferrin saturation would lead to a significant reduction in total screening costs. Additional benefits of a screening programme include detection of other iron overload disorders and iron deficiency. 相似文献

OBJECTIVE: To estimate the annual incidence, the mortality and the direct and indirect costs associated with occupational injuries and illnesses in the United States in 1992. DESIGN: Aggregation and analysis of national and large regional data sets collected by the Bureau of Labor Statistics, the National Council on Compensation Insurance, the National Center for Health Statistics, the Health Care Financing Administration, and other governmental bureaus and private firms. METHODS: To assess incidence of and mortality from occupational injuries and illnesses, we reviewed data from national surveys and applied an attributable risk proportion method. To assess costs, we used the human capital method that decomposes costs into direct categories such as medical and insurance administration expenses as well as indirect categories such as lost earnings, lost home production, and lost fringe benefits. Some cost estimates were drawn from the literature while others were generated within this study. Total costs were calculated by multiplying average costs by the number of injuries and illnesses in each diagnostic category. RESULTS: Approximately 6500 job-related deaths from injury, 13.2 million nonfatal injuries, 60,300 deaths from disease, and 862,200 illnesses are estimated to occur annually in the civilian American workforce. The total direct ($65 billion) plus indirect ($106 billion) costs were estimated to be $171 billion. Injuries cost $145 billion and illnesses $26 billion. These estimates are likely to be low, because they ignore costs associated with pain and suffering as well as those of within-home care provided by family members, and because the numbers of occupational injuries and illnesses are likely to be undercounted. CONCLUSIONS: The costs of occupational injuries and illnesses are high, in sharp contrast to the limited public attention and societal resources devoted to their prevention and amelioration. Occupational injuries and illnesses are an insufficiently appreciated contributor to the total burden of health care costs in the United States. 相似文献

Because lung cancer is a major health care problem in Canada, it would be useful to identify the direct health care costs of diagnosing and treating this disease and to create an analytic framework within which diagnostic and therapeutic options can be assessed. This paper describes a method of modelling the costs of care for lung cancer. The perspective of the costing model is that of the government as payer in a universal health care system. Clinical algorithms were developed to describe the management of non-small cell (NSCLC) and small cell (SCLC) lung cancer. Patients were allocated to the treatment algorithms in the model, based on a knowledge of the stage distribution of cases within provincial cancer registries and an estimate of the use of therapeutic modalities, according to lung cancer experts. A microsimulation model (POHEM) developed at Statistics Canada was used to integrate data on risk factors, disease onset and progression, health care resource utilization and direct medical care costs. The model incorporates survival data on patients, according to cell type and stage, based on published studies. Relapse and terminal care costs were assigned during the year of death, in order to determine the cost of continuing care and the cumulative cost of lung cancer management over time. Patients surviving five years were assumed to be cured. The model estimates that the total five year cost to provide care to the 15,624 cases of lung cancer diagnosed in Canada in 1988 was in excess of $328 million. Over 82% of this total was spent in the first year for diagnostic tests, therapy (surgery, chemotherapy, radiation therapy, or combinations of these), hospitalization and follow-up costs. The average five year cost per case was $21,000, and ranged from a high of $29,860 for limited disease SCLC, to a low of $16,500 for Stage IV NSCLC. The actual cost of providing care, including the management of complications, is unknown and our estimates should be regarded as an idealized estimate of the cost of lung cancer management. However, the POHEM model has a level of sophistication which, we believe, reasonably reflects the cost per case and total costs of treating lung cancer by stage and therapeutic modality in Canada. 相似文献
