National cost study versus hospital cost accounting for organ recovery cost assessment in a French hospital group.

BACKGROUND: The choice of cost data sources is crucial, because it influences the results of cost studies, decisions of hospital managers and ultimately national directives of policy makers. The main objective of this study was to compare a hospital cost accounting system in a French hospital group and the national cost study (ENC) considering the cost of organ recovery procedures. The secondary objective was to compare these approaches to the weighting method used in the ENC to assess organ recovery costs. METHODS: The resources consumed during the hospital stay and organ recovery procedure were identified and quantified retrospectively from hospital discharge abstracts and the national discharge abstract database. Identified items were valued using hospital cost accounting, followed by 2010-2011 ENC data, and then weighted using 2010-2011 ENC data. A Kruskal-Wallis test was used to determine whether at least two of the cost databases provided different results. Then, a Mann-Whitney test was used to compare the three cost databases. RESULTS: The costs assessed using hospital cost accounting differed significantly from those obtained using the ENC data (Mann-Whitney; P-value < 0.001). In the ENC, the mean costs for hospital stays and organ recovery procedures were determined to be €4961 (SD €7295) and €862 (SD €887), respectively, versus €12,074 (SD €6956) and €4311 (SD €1738) for the hospital cost accounting assessment. The use of a weighted methodology reduced the differences observed between these two data sources. CONCLUSIONS: Readers, hospital managers and decision makers must know the strengths and weaknesses of each database to interpret the results in an informed context.

Organ recovery cost assessment in the French healthcare system from 2007 to 2014.

Background: Organ recovery costs should be assessed to allow efficient and sustainable integration of these costs into national healthcare budgets and policies. These costs are of considerable interest to health economists, hospitals, financial managers and policy makers in most developed countries. This study assessed organ recovery costs from 2007 to 2014 in the French healthcare system based on the national hospital discharge database and a national cost study. The secondary objective was to describe the variability in the population of deceased organ donors during this period. Methods: All stays for organ recovery in French hospitals between January 2007 and December 2014 were quantified from discharge abstracts and valued using a national cost study. Five cost evaluations were conducted to explore all aspects of organ recovery activities. A sensitivity analysis was conducted to test the methodological choice. Trends regarding organ recovery practices were assessed by monitoring indicators. Results: The analysis included 12 629 brain death donors, with 28 482 organs recovered. The mean cost of a hospital stay was €7469 (SD = €10, 894). The mean costs of separate kidney, liver, pancreas, intestine, heart, lung and heart-lung block recovery regardless of the organs recovered were €1432 (SD = €1342), €502 (SD = €782), €354 (SD = €475), €362 (SD = €1559), €542 (SD = €955), €977 (SD = €1196) and €737 (SD = €637), respectively. Despite a marginal increase in donors, the number of organs recovered increased primarily due to improved practices. Conclusion: Although cost management is the main challenge for successful organ recovery, other aspects such as organization modalities should be considered to improve organ availability.

Mixed method versus full top-down microcosting for organ recovery cost assessment in a French hospital group.

BACKGROUND: The costing method used can change the results of economic evaluations. Choosing the appropriate method to assess the cost of organ recovery is an issue of considerable interest to health economists, hospitals, financial managers and policy makers in most developed countries. OBJECTIVES: The main objective of this study was to compare a mixed method, combining top-down microcosting and bottom-up microcosting versus full top-down microcosting to assess the cost of organ recovery in a French hospital group. The secondary objective was to describe the cost of kidney, liver and pancreas recovery from French databases using the mixed method. METHODS: The resources consumed for each donor were identified and valued using the proposed mixed method and compared to the full top-down microcosting approach. Data on kidney, liver and pancreas recovery were collected from a medico-administrative French database for the years 2010 and 2011. Related cost data were recovered from the hospital cost accounting system database for 2010 and 2011. Statistical significance was evaluated at P < 0.05. RESULTS: All the median costs for organ recovery differ significantly between the two costing methods (non-parametric test method; P < 0.01). Using the mixed method, the median cost for recovering kidneys was found to be €5155, liver recovery was €2528 and pancreas recovery was €1911. Using the full top-down microcosting method, median costs were found to be 21-36% lower than with the mixed method. CONCLUSION: The mixed method proposed appears to be a trade-off between feasibility and accuracy for the identification and valuation of cost components when calculating the cost of organ recovery in comparison to the full top-down microcosting approach.

Prophylactic radiofrequency ablation in asymptomatic patients with Wolff-Parkinson-White is not yet a good strategy: a decision analysis.

BACKGROUND: Therapeutic management of asymptomatic patients with a Wolff-Parkinson-White (WPW) pattern is controversial. We compared the risk:benefit ratios between prophylactic radiofrequency ablation and no treatment in asymptomatic patients with WPW. METHODS AND RESULTS: Decision analysis software was used to construct a risk-benefit decision tree. The target population consisted of 20- to 40-year-old asymptomatic patients with WPW without structural fatal heart disease or a family history of sudden cardiac death. Baseline estimates of sudden death and radiofrequency ablation complication rates were obtained from the literature, an empirical data survey, and expert opinion. The outcome measure was death within 10 years. Sensitivity analyses determined the variables that significantly impacted the decision to ablate or not. Threshold analyses evaluated the effects of key variables and the optimum policy. At baseline, the decision to ablate resulted in a reduction of mortality risk of 8.8 patients for 1000 patients compared with abstention. It is necessary to treat 112 asymptomatic patients with WPW to save one life over 10 years. Sensitivity analysis showed that 3 variables significantly impacted the decision to ablate: (1) complication of radiofrequency ablation, (2) success of radiofrequency ablation, and (3) sudden death in asymptomatic patients with WPW. CONCLUSIONS: This study provides a decision aid for treating asymptomatic patients with the WPW ECG pattern. Using the model and the population we tested, prophylactic catheter ablation is not yet ready for widespread clinical use.

Use of the monoclonal antibody anti-HER2 trastuzumab in the treatment of metastatic breast cancer: a cost-effectiveness analysis.

BACKGROUND: This open controlled prospective study aimed at evaluating the medical and economical impact of first line chemotherapy for metastatic breast cancer (MBC). PATIENTS AND METHODS: Two groups of HER +++ MBC patients were compared: 26 were treated by a combination of trastuzumab and paclitaxel in 4 "prescriber" centers (group A) and 19 patients were treated by any chemotherapy without addition of trastuzumab, in 6 control centers (group B). The cost of chemotherapy and related hospitalizations was taken into account during the first 8 cycles. RESULTS: Forty-five patients, mean age 51 years have been included. The objective response rate was significantly higher in group A (42% vs. 6%, P = 0.036). The median overall survival was 17 months longer in the group A (29 vs. 12 months). The median progression free survival rate was 12.2 months longer in the group A (19 vs. 7 months). The 1-year survival rate was 85% in the group A and 47% in the group B. The mean overall care cost was 33.271 euro per patient in group A versus 11.191 euro per patient in group B. The additional cost per saved year of life expressed as the incremental cost-effectiveness ratio is 15.370 euro 2002. CONCLUSION: The related additional cost seems affordable for an European health care system and justifies the recommendation for its use in the subpopulation overexpressing HER2.

Evolution of costs of care for cystic fibrosis patients after clinical guidelines implementation in a French network.

OBJECTIVES: The aim of this study was to evaluate how advances in CF management in France between 2000 and 2003 impacted CF-related costs. METHODS: The analysis of direct medical costs was done in 2000 and 2003 from the perspective of the French national healthcare insurance system. The patients, 65 in 2000 and 64 in 2003, were followed-up in one pediatric and one adult CF reference center (CFRC). We quantified and valued CF-related home and hospital care costs. RESULTS: We found an average cost of euro16474/patient/year in 2000, and euro22725 in 2003 (based on the 2003 euro value). Hospital care increased from 15% of the total cost in 2000 to 22% in 2003. Medications accounted for 45% of the total cost for the two periods, with an average cost of euro7229/patient/year in 2000 and euro10336 in 2003. Home intravenous antibiotic therapy accounted for 20% of the total cost for the two periods. CONCLUSIONS: We highlighted an increase in CF care costs between 2000 and 2003, which might be related to the changes in practice patterns that followed guidelines implementation, such as the use of new medications (dornase alpha and tobramycin) and more frequent follow-up in the CFRC.

[Methodology of economic assessment: example in oncology]. / Méthodes d'évaluation médico-économique : applications à la cancérologie.

The increasing costs of care make it important to identify those strategies of greatest value from both an effectiveness and cost perspective. Economic analysis is characterized by a simultaneous consideration of alternatives costs and outcomes, and can provide useful data for managerial decision making. In this paper, methods of economic evaluations in general and in cancer in particular is reviewed. In cancer treatment, preventive, curative or palliative strategies can be concerned. Economic evaluation have become increasingly important in oncology because of the proliferation of expensive new treatments. Furthermore, considering quality of life effects is particularly important in oncology, where many treatments obtain modest improvements in response or survival. Quality of life measurements are also reviewed.

In an era where health care expenditure control is a necessity, weighing a new treatment's cost against its added benefits is of crucial importance. These medico-economic analyses may be planned for the evaluation of new molecules in their daily use. Different methods may be used. The medico-economic evaluation of a drug can be performed with the use of clinical studies or modelization techniques. "Clinical studies" include the following methods: randomized trials, so-called "experimental", non-randomized studies, and observational studies. This classification follows a downward evolution of both the investigator's intervention power and the level of proof. Finally, modelization is becoming a commonly used tool. Randomized trials are the "gold standard" but the other, more pragmatic study types, providing a lesser degree of proof can complete the evaluation of a new molecule. One must find the best compromise between the study's objectives and the study type.
