The HTA core model: a novel method for producing and reporting health technology assessments.

OBJECTIVES: The aim of this study was to develop and test a generic framework to enable international collaboration for producing and sharing results of health technology assessments (HTAs). METHODS: Ten international teams constructed the HTA Core Model, dividing information contained in a comprehensive HTA into standardized pieces, the assessment elements. Each element contains a generic issue that is translated into practical research questions while performing an assessment. Elements were described in detail in element cards. Two pilot assessments, designated as Core HTAs were also produced. The Model and Core HTAs were both validated. Guidance on the use of the HTA Core Model was compiled into a Handbook. RESULTS: The HTA Core Model considers health technologies through nine domains. Two applications of the Model were developed, one for medical and surgical interventions and another for diagnostic technologies. Two Core HTAs were produced in parallel with developing the model, providing the first real-life testing of the Model and input for further development. The results of formal validation and public feedback were primarily positive. Development needs were also identified and considered. An online Handbook is available. CONCLUSIONS: The HTA Core Model is a novel approach to HTA. It enables effective international production and sharing of HTA results in a structured format. The face validity of the Model was confirmed during the project, but further testing and refining are needed to ensure optimal usefulness and user-friendliness. Core HTAs are intended to serve as a basis for local HTA reports. Core HTAs do not contain recommendations on technology use.

The adaptation of health technology assessment reports: identification of the need for, and development of, a toolkit to aid the process.

OBJECTIVES: Europe has many health technology assessment (HTA) agencies, each producing their own HTA reports. Adapting HTA reports for different contexts could reduce the need for multiple reports on the same health technology with resultant saving of time and resources. This study aims to examine and understand the process of adaptation, and to develop a toolkit that would help the adaptation of reports produced by other countries. METHODS: The methods used were a review of the literature; a survey of twenty-nine European HTA organizations, two rounds of a Delphi survey, a face-to-face meeting of twenty-one European network for Health Technology Assessment (EUnetHTA) representatives, iterative rounds of review, and two rounds of quality assurance testing (termed applicability testing). RESULTS: Descriptions of previous examples of adaptation in the literature are sparse. Most respondents had previous experience in adapting reports, and all believed that adaptation was useful, and there was the ability to benefit from the use of a toolkit to aid in the process. EUnetHTA Partners developed and tested an adaptation toolkit. The toolkit is composed of a series of checklists and resources that identify or clarify the relevance, reliability, and transferability of data and information from existing reports. CONCLUSIONS: Consensus of opinion from twenty-nine European organizations/networks has indicated that the adaptation of HTA reports would be desirable and beneficial. A toolkit was developed to help with the adaptation of HTA reports produced in other settings. This collection of resources is available for use by all HTA agencies and can be accessed at: http://www.eunethta.net/upload/WP5/EUnetHTA_HTA_Adaptation_Toolkit_October08.pdf.

The health technology assessment adaptation toolkit: description and use.

OBJECTIVES: Adapting health technology assessment (HTA) reports for different contexts could reduce the need for multiple reports on the same health technology with resultant saving of time and resources. This article describes an instrument, the adaptation toolkit, which has been developed to aid in the process of adaptation of HTA reports. METHODS: The toolkit was developed by a partnership of HTA agencies and networks from across Europe. The role of the toolkit is to guide the user through the process of selecting possible relevant material from these report(s), assessing the relevance, reliability, and transferability of the material, and adapting it for the desired context. RESULTS: The adaptation toolkit has been developed, it comprises a collection of resources that help the user assess whether data and information in existing HTA reports should and could be adapted for their own setting. The toolkit contains two sections: a preliminary speedy sifting section and the main toolkit. The main toolkit includes five domains: (i) technology use and development, (ii) safety, (iii) effectiveness (including efficacy), (iv) economic evaluation, and (v) organizational aspects. Legal, ethical, and social aspects are beyond the scope of the toolkit. The toolkit is designed for the adaptation of evidence synthesis rather than primary research. CONCLUSIONS: The completed current version of the toolkit contains checklists and resources to aid in the adaptation of HTA reports. This collection of resources is available for use by all HTA agencies and can be accessed at: http://www.eunethta.net/upload/WP5/EUnetHTA_HTA_Adaptation_Toolkit_October08.pdf..

Enhancing understanding: the development of a glossary of health technology assessment adaptation terms.

BACKGROUND: The way people use health technology assessment (HTA) terms varies considerably across Europe. Such variation can lead to misunderstandings when reading HTA reports from different contexts. This work is one of the outputs of the EUnetHTA Project and was undertaken between 2006 and 2008. OBJECTIVES: The aim of this study was to develop a glossary of HTA adaptation terms to help reduce the misunderstandings of terms used in HTA reports from contexts other than the reader's own. METHODS: Several HTA glossaries were examined to identify ways in which an additional glossary could offer readers something new and to identify adaptation terms for inclusion. Twenty-eight European HTA organizations provided terms for the glossary and drafted descriptions and examples of how each specific term was used in their particular setting. The organizations then commented on the descriptions provided by the other groups and worked together to draft a single description for certain terms. RESULTS: A glossary of HTA adaptation terms was developed. It provides a comprehensive range of descriptions, examples, and comments for forty-two potentially confusing HTA terms related to adaptation. CONCLUSIONS: This glossary will be a valuable resource for European HTA agencies when reading HTA reports produced in different contexts and for adapting HTA reports produced in other countries. The glossary will help improve understanding and help facilitate the adaptation process.
