Clinical Trial Summary

The aim of this project is to (1) evaluate the efficiency of early management of sarcoma patients by the sarcoma referral network (NETSARC) vs. outside the network; (2) measure the budgetary impact of the generalization of the most cost-effective strategy across the country; (3) identify the organizational and financial constraints likely to hinder the generalization of the most cost-effective strategy and propose solutions, and finally (4) analyse the budgetary impact of a generalization of sarcoma patient care by the reference network by integrating the organizational and financial solutions proposed.

The study relies on an exhaustive national cohort of all sarcoma patients who underwent primary tumor surgery for the year 2013. Patients will be allocated to four distinct strategies, each representing a different management of sarcoma patients who had a sarcoma-specialized multidisciplinary tumor board (MDTB) before the initial surgery and complete initial management in the network (strategy 1); patients who had a sarcoma-specialized MDTB before the initial surgery and initial management outside the network (strategy 2); patients who had a sarcoma-specialized MDTB after initial surgery and initial management outside the network (strategy 3); patients who had an initial management outside the network, without sarcoma-specialized MDTB neither before nor after the initial surgery (strategy 4).

Matching of the National Health Data System (SNDS) and the NETSARC databases made it possible to include 2431 patients in the study. These databases will allow to obtain information on patients, estimate overall survival and identify healthcare consumption, which will be useful in achieving study's objectives.

Description:

Introduction

Sarcomas are a large family of rare and heterogeneous tumors. As a consequence, their diagnosis and management are difficult and complex, which can lead to misdiagnosis and suboptimal patient management. Thus, in 2009, the National Cancer Institute (INCa) and the "Direction Générale de l'Offre de Soins" (DGOS) supported the creation of a sarcoma reference network (NETSARC) with the aim to guarantee optimal care for sarcoma patients. Numerous studies show that initial patients' management in the sarcoma referral network reduces the risk of death and relapse. However, the proportion of sarcoma patients initially managed within the referral network is still too low today. The aim of this project is to (1) evaluate the efficiency of early management of sarcoma patients by the sarcoma referral network vs. outside the network; (2) measure the budgetary impact of the generalization of the most cost-effective strategy across the country; (3) identify the organizational and financial constraints likely to hinder the generalization of the most cost-effective strategy and propose solutions, and finally (4) analyses the budgetary impact of a generalization of sarcoma patient care by the reference network by integrating the organizational and financial solutions proposed.

Methods and analysis

The study relies on an exhaustive national cohort of all sarcoma patients (ICD code 10 C49, C48 or C40-41) who underwent primary tumor surgery for the year 2013. Patients will be allocated to four distinct strategies, each representing a different management of sarcoma patients: patients who had a sarcoma-specialized multidisciplinary tumor board (MDTB) before the initial surgery and complete initial management in the network (strategy 1); patients who had a sarcoma-specialized MDTB before the initial surgery and initial management outside the network (strategy 2); patients who had a sarcoma-specialized MDTB after initial surgery and initial management outside the network (strategy 3); patients who had an initial management outside the network, without sarcoma-specialized MDTB neither before nor after the initial surgery (strategy 4).

Matching of the National Health Data System (SNDS) and the NETSARC databases made it possible to include 2431 patients in the study. These databases will allow to obtain information on patients, estimate overall survival and identify healthcare consumption, which will be useful to achieve study's objectives.

The evaluation of early management of operable sarcoma patients by the sarcoma reference network vs. outside the network will be based on three approaches which are both distinct and complementary in terms of decision support. (1) Firstly, an efficiency assessment based on a cost-effectiveness analysis (CEA) and a cost-utility analysis (CUA) will be carried out. The short-term CEA will use the Incremental Cost-Effectiveness Ratio (ICER) expressed as cost per life year gained, while the long-term CUA will use the ICER expressed as cost per quality-adjusted life year (QALY) gained. The efficiency analysis will be complemented by a Budget Impact Analysis (BIA) based on an estimate of the additional and avoided costs induced by the generalization of the most cost-effective strategy determined in the previous steps. (2) Next, an organizational evaluation focusing on a flow analysis will be carried out. (3) Finally, an innovative financing model will be developed to encourage inter-center cooperation.

Ethics and dissemination

The OPTISARC project will be conducted in accordance with the ethical principles of the latest version of the Declaration of Helsinki developed by the World Medical Association (WMA). This study falls within the framework of research not involving the human person, study or health assessment (RNIPH) and will be conducted in accordance with the French and European laws and regulations in force, as well as any other applicable guidelines.

This Project has obtained a favorable opinion from the "Comité d'Expertise pour les Recherches, les Etudes et les Evaluations dans le domaine de la Santé" (CEREES) and an authorization from the "Comité National Informatique et Liberté" (CNIL) allowing the access to SNDS data (DCIR and PMSI) from 2013 to 2018.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Short-term cost-effectiveness analysis	The main objective of this study is to evaluate the short-term effectiveness (over a 5-year period) of sarcoma patient management by the sarcoma referral network vs. outside the network. A cost-effectiveness analysis (CEA) based on the Incremental Cost-Effectiveness Ratio (ICER) will be used to compare strategies 1, 2, 3 and 4.	5 years
Secondary	Long-term cost-utility analysis and cost-effectiveness analysis	In accordance with the High Authority of Health (Haute Autorité de Santé - HAS, in French) requirements, the short-term cost-effectiveness analysis (CEA) will be supplemented by a whole-life cost-utility analysis (CUA) (and a whole-life CEA) to assess the efficiency of sarcoma patient management by the sarcoma referral network vs. outside the network. More specifically, an extrapolation to a time frame of 15 years will be used to achieve this whole-life CUA. In the same way as the short-term CEA, the whole-life CUA and CEA will use the ICER to compare strategies 1, 2, 3 and 4 with each other.	15 years
Secondary	Budget Impact Analysis	The decision to include a Budget Impact Analysis (BIA) in this study is in line with the framework agreement signed in January 2016 between the Economic Committee for Medicinal Products (Comité Economique des Produits de Santé - CEPS, in French) and the Pharmaceutical Industry (Les Entreprises du Médicament - LEEM, in French), which advises the implementation of a BIA in addition to the medico-economic study. The BIA will strictly comply with the HAS requirements presented in its methodological guide for BIA.	5 years
Secondary	Organizational Assessment	A quantitative comparison of the pathway models of the four strategies with reference pathway models (calculation of the distance between the models) will be accomplish.	5 years
Secondary	Define the incentive mechanisms most likely to neutralize the main obstacles identified in a theoretical model of cooperation	Measurement tool: discrete choice questionnaire (validated by an ethical committee) with several scenarios, administered to a panel of health professionals from the sarcoma expert centers and local centers.; The objective is to reveal the preferences of professionals for different modalities of cooperation in order to maximise their willingness to modify their current practices, whether they are in reference or peripheral centres, in the direction of greater complementarity. The method used for this investigation will be based on the design, implementation and analysis of data from a discrete choice experiment. More precisely, it is a method based on stated preferences in which the respondents are placed in a hypothetical choice situation.	5 years
Secondary	Pricing model	Measurement: in euros 2022 - Cost impact of a transition from diagnosis related groups (DRG) to bundle payment; To establish a pricing model that can be implemented in France, to improve the quality of care by encouraging health establishments to cooperate.	5 years
