[Medical and economic evaluation of organ transplantation in France. The example of liver transplantation].

BACKGROUND: Organ transplantation is an expensive and risky medical procedure. Estimating the cost is difficult because the care is complex and involves many actors. We present a methodological framework for the economic evaluation of organ transplantation in France which include a detailed collection of all the direct costs and the simultaneous analysis of health status. It was applied to evaluate the cost of liver transplantation in France. METHODS: All consecutive adults transplanted or placed on the waiting list of liver transplantation in the Department of Surgery of Cochin Hospital, Paris, between 1994 and 1996 were included. All resource use was measured during one year: staff wages, pharmacy and blood, laboratory and radiology, supplies, overhead hospital services. Mean quality of life was estimated by the survival weighted by the Karnofsky index. RESULTS: Transplantation: 38 patients were included. The first year mean cost after transplantation was 561,000FF (included rehospitalizations cost of 120,000FF). Care outside the hospital induced 10% of the total cost. Mean quality of life was 63% (from 0% to 93%) and increased with time, whereas cost decreased. Waiting list: 26 of 33 patients on waiting list were transplanted. The first year mean cost was 95,000FF (included 32,000FF for first evaluation) and increased with time. 44% of cost was supported by another hospital than the transplanting one. Sickness allowance added 20% to the cost. The mean quality of life was 56% during the first year. CONCLUSIONS: This complete approach of organ transplantation cost respected the medical procedure over the time. Detailed costs take into account the care outside the hospital. This method can be used in other countries and generalised to all surgical or medical procedure as heavy as the organ transplantation.

Direct cost analyses of palivizumab treatment in a cohort of at-risk children: evidence from the North Carolina Medicaid Program.

OBJECTIVE: Use of palivizumab prophylactic therapy reduces the occurrence of hospitalizations for serious respiratory syncytial virus (RSV) lower respiratory tract infections in at-risk infants. The direct cost-benefit of palivizumab prophylaxis for infants who are born at 32 to 35 weeks' estimated gestational age (EGA) during their first year of life has not been systematically examined. The objective of this study was to compare the direct costs of palivizumab prophylaxis and RSV treatment in infants who were born at 32 to 35 weeks EGA and received and did not receive palivizumab. METHODS: A cohort study was performed of infants who were younger than 1 year and were enrolled in an enhanced primary care case management model within the North Carolina Medicaid Program. Comparisons were made between infants who received (Synagis prophylaxis group) and did not receive palivizumab (nonprophylaxis group) during the study period. Cost was examined using the sum of Medicaid paid services for prophylaxis with palivizumab and treatment for RSV infections that occurred between October 1, 2002, and May 31, 2003. The Anderson framework was used to specify the regression cost models to compare the participants who received (Synagis prophylaxis) and did not receive (nonprophylaxis group) palivizumab. The primary outcomes were actual 7-month seasonal costs and standardized seasonal costs adjusting for the varied months of infant participation. RESULTS: The study sample included 185 Synagis prophylaxis and 182 nonprophylaxis participants who met the inclusion criteria. The average per-person total cost of RSV care and prophylaxis was 5117 dollars for the Synagis prophylaxis group and 371 dollars for the nonprophylaxis group. Five hospitalizations occurred in the prophylaxis group, and 12 occurred in the nonprophylaxis group (odds ratio: 0.27). No deaths occurred in either group. CONCLUSIONS: Palivizumab administered to infants who were born at 32 to 35 weeks' EGA did not provide direct cost savings related to hospitalization or ambulatory care in a Medicaid population. The primary difference in cost between the groups was attributable to the palivizumab prophylaxis.

Cost-effectiveness analysis of Malaysian neonatal intensive care units.

OBJECTIVE: To perform a cost-effective analysis on the care of infants between 1000 and 1500 g birthweight (the study group), where outcomes are measured as survival to 1 year of age. METHODOLOGY: This was a multicenter observational study to determine the outcome, cost and cost-effectiveness of neonatal intensive care provided by Ministry of Health (MOH) Pediatric services. A total of 333 patients enrolled were eligible for analysis according to the inclusion and exclusion criteria of this study. RESULTS: Overall survival probability of the study group infants at 1 year of age was 78%. Survival at 1-year of age was 77% for infants with birth weight 1000 to 1249 g, 79% for 1250 to 1499 g. Survival at 1 year of age for the sample group was 53% for 22 to 27 weeks gestation, 80% for 28 to 36 weeks. The average cost-effectiveness ratio (CER) of neonatal intensive care for the study group infants was US$3979 [corrected] per survivor at 1 year of age (95% confidence interval US$3411, 5160). CONCLUSION: There was variability in the outcome and cost-effectiveness between the neonatal units, which need to be further assessed. However, neonatal intensive care services provided for the study group infants were cost-effective compared to that in developed countries.

[Ambulatory medical care in Mexico: the cost for users].

OBJECTIVE: To analyze the results of the National Health Survey (ENSA-II) as to the costs generated by the search and obtainment of ambulatory medical attention in various institutions of the private and public health sector. MATERIAL AND METHODS: Information was raised from the health care cost indicators reported by the study population of the ENSA-II. The dependent variable was the direct expense for the consumer and the independent variables, the condition of being insured and the income. Variation significance levels were identified using the test by Duncan. RESULTS: The costs at national level in US dollar were: transport $2.20, medical visit $7.90, drugs $9.60, diagnostic studies $13.6; average total cost for ambulatory attention was $22.70. Empirical finding suggest a new direct and indirect cost-for-consumer analysis for the health care users. These costs represent an important burden on the family income, which worsens when users are not insured. CONCLUSIONS: Incorporation of the economic perspective to the analysis of public health issues should not be limited to the analysis of the health provider's expenses, particularly if the problems of equity and accessibility must be solved, which are at present characteristic of health care services in Mexico.

Using horsechestnut seed extract in the treatment of venous leg ulcers: a cost-benefit analysis.

Venous leg ulcers affect approximately 0.6% of the western population, consuming millions of healthcare dollars every year. To determine whether an alternative venous ulcer treatment using horsechestnut seed extract-- Aesculus hippocastanum-- and conventional therapy involving dressings and compression was more cost-effective than using conventional therapy alone, a 12-week cost-benefit analysis of horsechestnut seed extract therapy was conducted. The study, using data from a 12-week prospective, randomized, placebo-controlled trial conducted in South Australia in 2002-2004, involved 54 patients with venous ulceration who received treatment through a large South Australian district nursing service. Taking into account the cost of horsechestnut seed extract, dressing materials, travel, staff salaries, and infrastructure for each patient, horsechestnut seed extract therapy combined with conventional therapy was found to be more cost-effective than conventional therapy alone with an average savings of AUD 95 in organizational costs and AUD 10 in dressing materials per patient. This study confirms that dressing change frequency has a significant impact on the total cost of wound care and suggests that district nursing service operation efficiency may be enhanced through the use of horsechestnut seed extract as a result of less frequent nursing visits. Further study of this treatment modality is warranted.

Cost evaluations in epilepsy: an update.

The purpose of this article is to describe the developments in the methodology of studies of the cost of epilepsy and cost-effectiveness of treatments in light of previous reviews and recently published methodological guidelines. Several recent studies are compared, with recently published guidelines by the US Public Health Service (PHS) serving as a framework for discussing selected methodological issues. Results show that these recent studies have made important gains in the quality of cost data obtained, with advances being made by studies that base cost estimates on actual patient data from representative samples as opposed to secondary sources and expert opinions. However, a wide variety of methods continue to be used for many aspects of study design and reporting. Method heterogeneity remains an obstacle to presenting and interpreting reliable and valid information on costs and cost-effectiveness. Areas in need of additional development are methods for estimating direct nonmedical costs, attributing costs to epilepsy versus comorbid conditions, validating health state valuation methods for this population, and validating current recommendations for capturing the costs of lost productivity due to epilepsy. PHS panel recommendations provide a useful framework for working toward consistency in the methods for economic studies in epilepsy.

A cost and value analysis of two interventions with incontinent nursing home residents.

OBJECTIVE: More than half of nursing home residents suffer from urinary incontinence. These residents typically have long stays and, because of comorbid cognitive and physical impairments, have little hope of living again in a noninstitutional environment The value of interventions to change functional status of this chronically institutionalized population is often questioned. This paper explores this value issue in the context of two incontinence management interventions that have been shown to improve functional status: (1) Functional Incidental Training (FIT), and (2) Prompted Voiding (PV). The relative value of the different interventions for the nursing home population was estimated using paired preferences. DESIGN: The cost of two interventions (FIT and PV) that target incontinent nursing home residents was related to the value of these interventions as perceived by consumers of nursing home services. Both interventions decrease incontinence frequency, and one intervention also improves mobility endurance. PARTICIPANTS: Ninety incontinent nursing home residents received the intervention; 37 older nondemented board and care residents and 31 family members of the nursing home residents provided estimates of the intervention's value. MEASUREMENT: The staff-time allocations involved in implementing both interventions were documented in more than 85 resident care episodes. These time data were converted to labor cost based on the cost of nursing aides who would actually implement the intervention. The value of each intervention was assessed by asking consumers to make choices between the intervention and its associated outcomes (such as increased dryness) and other nursing home services of known cost (e.g., moving to a private room). RESULTS: Both interventions had labor costs that were greater than "usual care" costs. The additional cost was estimated to be $4.31 per resident per day for PV and $6.42 per resident per day for FIT if these programs were implemented from 7 AM to 7 AM. Consumer preference data indicated that consumers preferred the FIT and PV outcomes to more expensive alternative services, calculated to cost $10.00 per day, often marketed to consumers, CONCLUSION: Consumers may prefer the FIT and PV interventions relative to the typical services often marketed to the nursing home consumer. The analysis completed in this paper suggests that both interventions have value for frail residents likely to live out their lives in a nursing home.

Costs in rheumatology: results and lessons learned from the 'Hannover Costing Study'.

The objective of this study is to review the concept of the 'Hannover Costing Study' and to present and discuss the major insights generated during the course of the project. The costing study was performed in conjunction with a randomized controlled prospective trial assessing the effectiveness of a disease management module in rheumatoid arthritis (RA). A full set of clinical and cost data both from patient-reported and payer-derived cost data was developed. In particular the study included (1) the development of a matrix of cost domains which might be used as a common taxonomy in costing studies, (2) the descriptive analysis of payer derived cost data, (3) the analysis of cost data in patients with uncertain diagnosis; (4) the development and validation of a patient-reported costing instrument, and (5) an assessment of productivity costs. The following are the results (1) the developed matrix of cost domains included 16 separate cost domains: 7 outpatient, 3 inpatient, 4 other disease related, and 2 productivity domains; (2) the micro-costing analysis showed total direct costs of 3,815 per patient-year (standard error of mean, SEM: 267) and RA-related direct costs were 2,312 per patient-year; (3) in patients with uncertain diagnosis of RA and no treatment with 'Disease Modifying Antirheumatic Drugs' (DMARD) costs were significantly lower; (4) the comparison of patient-reported with payer-reported cost data generally supports the use of highly aggregated items to assess health care utilization in RA; (5) productivity costs in patients that are gainfully employed and in patients who receive RA-related retirement payments exceed RA-related direct costs. Furthermore, RA-patients reported their productivity losses adequately. The study added some additional insights to the following questions: What costs should be collected, what level of detail is required for that task, what patients should by analyzed, and what data sources should be used in further studies in RA.

The economic burden of anxiety disorders in the 1990s.

BACKGROUND: We assess the annual economic burden of anxiety disorders in the United States from a societal perspective. METHOD: Using data from the National Comorbidity Study, we applied multivariate regression techniques to calculate the costs associated with anxiety disorders, after adjusting for demographic characteristics and the presence of comorbid psychiatric conditions. Based on additional data, in part from a large managed care organization, we estimated a human capital model of the societal cost of anxiety disorders. RESULTS: We estimated the annual cost of anxiety disorders to be approximately $42.3 billion in 1990 in the United States, or $1542 per sufferer. This comprises $23.0 billion (or 54% of the total cost) in nonpsychiatric medical treatment costs, S13.3 billion (31%) in psychiatric treatment costs, $4.1 billion (10%) in indirect workplace costs, $1.2 billion (3%) in mortality costs, and $0.8 billion (2%) in prescription pharmaceutical costs. Of the $256 in workplace costs per anxious worker, 88% is attributable to lost productivity while at work as opposed to absenteeism. Posttraumatic stress disorder and panic disorder are the anxiety disorders found to have the highest rates of service use. Other than simple phobia, all anxiety disorders analyzed are associated with impairment in workplace performance. CONCLUSION: Anxiety disorders impose a substantial cost on society, much of which may be avoidable with more widespread awareness, recognition, and appropriate early intervention.

Follow-up of breast cancer in primary care vs specialist care: results of an economic evaluation.

A randomized controlled trial (RCT) comparing primary-care-centred follow-up of breast cancer patients with the current standard practice of specialist-centred follow-up showed no increase in delay in diagnosing recurrence, and no increase in anxiety or deterioration in health-related quality of life. An economic evaluation of the two schemes of follow-up was conducted concurrent with the RCT Because the RCT found no difference in the primary clinical outcomes, a cost minimization analysis was conducted. Process measures of the quality of care such as frequency and length of visits were superior in primary care. Costs to patients and to the health service were lower in primary care. There was no difference in total costs of diagnostic tests, with particular tests being performed more frequently in primary care than in specialist care. Data are provided on the average frequency and length of visits, and frequency of diagnostic testing for breast cancer patients during the follow-up period.

Cost of allogeneic and autologous blood transfusion in Canada. Canadian Cost of Transfusion Study Group.

OBJECTIVE: To determine the cost, from a societal perspective, of blood transfusion in Canada. STUDY DESIGN: Cost-structure analysis. SETTING: Data were collected from eight hospitals and from six blood centres operated by the Canadian Red Cross Society in four provinces. OUTCOME MEASURES: Costs associated with four stages of transfusion-- collection, production, distribution and delivery--in 1933 were assessed. Costs were divided into the following categories; personnel, purchases, external services, overhead, donors' time, patients' time (for autologous transfusion), wastage and infection. RESULTS: The mean overall cost of a transfusion performed on an inpatient basis was $210 per unit of red blood cells for an allogeneic transfusion and $338 per unit of blood for an autologous transfusion. The mean cost of an allogeneic transfusion performed on an outpatient basis was $280 per unit of red blood cells. CONCLUSION: The costs determined in this study can be used in future studies comparing the cost-effectiveness of allogeneic transfusion with that of alternative methods.

The cost of MRI: changes in costs 1989-1996.

A study was conducted to provide an up-to-date analysis of the costs associated with operating an MRI facility in a mainstream National Health Service (NHS) setting. This paper presents an analysis of the costs associated with the acquisition and operation of an MRI scanner installed at the Walsgrave NHS Trust in Coventry in 1988. Costs arising immediately after the introduction of the MRI facility in 1988 are compared with the costs arising towards the end of the scanner's useful life during the 1995/96 financial year. The findings suggest that although the nominal total costs of MRI have increased marginally, from 403,223 Pounds to 434,037 Pounds (an increase of 30,814 Pounds), the increase in total costs is below the rate of inflation, and the nominal average costs of MRI have fallen from 179.20 Pounds to 115.77 Pounds over the period.

The economic cost of illness: fiscal 1975.

In 1963, Rice estimated the costs of illness and then allocated these costs by disease. She and Cooper in 1972 updated the original estimates and developed a more sophisticated methodological approach. This paper updates further the costs of illness to 1975 and presents further methodological changes. Analysis of the direct and indirect costs of illness for 1975 reveals that the upward trend into total costs continued, reaching $264 billion. The indirect costs are loss of earnings due to morbidity or premature mortality estimated at various discount rates allocated into 18 categories by disease. The direct costs include such payments as those made for hospital care, physician services, and drugs which are allocated by disease and unallocated costs such as construction and research. The proportion of total costs due to premature mortality were found to drop slightly from 1972 to 1975, while the morbidity share increased slightly. Direct costs account for approximately the same share of total illness in 1975 as in 1972. The proportion of total costs accounted for by direct costs varies directly with the discount rate selected, with the direct costs accounting for 50 per cent of the total at the 10 per cent discount rates and 37 per cent at 2.5 per cent rate. The proportion due to morbidity costs also varies directly with the discount rate, although the changes are small. There is an inverse relationship between the share for premature mortality costs and discount rate.

The cost of urinary incontinence in Italian women. A cross-sectional study. Gruppo di Studio Incontinenza.

OBJECTIVE: To offer cost estimates of urinary incontinence (UI) in the general population based on prospectively collected data. DESIGN: We analyzed individual costs in a sample of women with UI who were identified in the framework of a cross-sectional study on the prevalence of UI in women aged > 40 years. SETTING: Six areas in Italy. INTERVENTION: Home interview. PATIENTS AND PARTICIPANTS: Women were identified among the patients registered with a network of general practitioners operating in each area using computer-generated random number lists. RESULTS: A total of 2767 women were identified. Of these, 408 (14.7%) reported UI during the year before the interview and 229 underwent a detailed interview on UI-related costs. On the basis of this information, we estimated the direct costs associated with UI from the perspective of the Italian National Health Service (INHS). The lifetime cost per patient of diagnosis was 80,131 Italian lire (L) (exchange rate: $US1 = L1618). Consultations accounted for only 20% of the diagnostic cost, diagnostic tests for 36% and hospital admissions for diagnostic procedures accounted for 44%. The diagnosis cost estimate seems low, partly because several women did not request either consultations or diagnostic tests (the overall rate per patient was 0.76 for consultations and 0.39 for diagnostic tests). The only appreciable treatment cost, according to the INHS perspective, was for diapers. The annual cost per patient for diapers was L255,519. The prevalence of UI in women aged > 40 years in Italy is estimated in the study at 9.3%. Thus, combining this information with the cost estimates, the annual treatment cost of UI in Italian women aged > 40 years is L351,800 billion, considering diapers and drugs only. CONCLUSION: This study has estimated the individual cost of UI in the general population. These figures may be useful when designing economic evaluations of UI.
