INTRODUCTION:Increasing numbers of research papers about information retrieval for Health Technology Assessments (HTA), systematic reviews and other evidence syntheses are being published. It is time-consuming for information specialists to keep up-to-date with the latest developments in the field. To help searchers with this challenge, the Interest Group on Information Retrieval (IRG) of Health Technology Assessment International (HTAi) has compiled the best available research evidence on information retrieval aspects into an open-access web resource: Summarized Research in Information Retrieval for HTA (SuRe Info). The resource can be accessed at http://www.sure-info.orgMETHODS:The Sure Info team run topic-specific search strategies in selected relevant databases to identify information retrieval methods publications that fulfil the SuRe Info inclusion criteria. Eligible publications receive a structured abstract containing a brief critical appraisal. Key messages for search practice based on the appraisals and accepted best practice are summarized into topic-specific chapters.RESULTS:SuRe Info currently offers fourteen chapters, with more in development. SuRe Info chapters fall into two categories: (i) chapters about general search methods that are used across all types of research, such as how to develop search strategies and the availability and use of search filters, and (ii) chapters summarizing the methods to use when searching for specific aspects of HTA (as defined in the European Network for HTA (EUnetHTA) HTA Core Model®), including searching for evidence on clinical effectiveness and safety, and identifying economic evaluations. References at the end of each chapter are linked to appraisals of publications that have been used to develop each chapter. Links to the full-text of the publications are provided when freely available. The SuRe Info chapters are reviewed every six months and updated if new evidence is identified or if resources change.CONCLUSIONS:SuRe Info is a unique resource, identifying and summarizing current best research evidence on information retrieval aspects for HTA. It supports the timely uptake of potential efficiencies arising from new evidence that may be incorporated into the evidence identification processes of HTA organizations.

Objectives:This study investigated which databases and which combinations of databases should be used to identify economic evaluations (EEs) to inform systematic reviews. It also investigated the characteristics of studies not identified in database searches and evaluated the success of MEDLINE search strategies used within typical reviews in retrieving EEs in MEDLINE.Methods:A quasi-gold standard (QGS) set of EEs was collected from reviews of EEs. The number of QGS records found in nine databases was calculated and the most efficient combination of databases was determined. The number and characteristics of QGS records not retrieved from the databases were collected. Reproducible MEDLINE strategies from the reviews were rerun to calculate the sensitivity and precision for each strategy in finding QGS records.Results:The QGS comprised 351 records. Across all databases, 337/351 (96 percent) QGS records were identified. Embase yielded the most records (314; 89 percent). Four databases were needed to retrieve all 337 references: Embase + Health Technology Assessment database + (MEDLINE or PubMed) + Scopus. Four percent (14/351) of records could not be found in any database. Twenty-nine of forty-one (71 percent) reviews reported a reproducible MEDLINE strategy. Ten of twenty-nine (34.5 percent) of the strategies missed at least one QGS record in MEDLINE. Across all twenty-nine MEDLINE searches, 25/143 records were missed (17.5 percent). Mean sensitivity was 89 percent and mean precision was 1.6 percent.Conclusions:Searching beyond key databases for published EEs may be inefficient, providing the search strategies in those key databases are adequately sensitive. Additional search approaches should be used to identify unpublished evidence (grey literature).

Background: Information retrieval (IR) in health technology assessment (HTA) calls for transparency and reproducibility, but common practice in the documentation and presentation of this process is inadequate in fulfilling this demand.Objectives: Our objective is to promote good IR practice by presenting the conceptualization of retrieval and transcription readable to non-information specialists, and reporting of effectively processed search strategies.Methods: We performed a comprehensive database search (04/2010) to synthesize the current state-of-the-art. We then developed graphical and tabular presentation methods and tested their feasibility on existing research questions and defined recommendations.Results: No generally accepted standard of reporting of IR in HTA exists. We, therefore, developed templates for presenting the retrieval conceptualization, database selection, and additional hand-searching as well as for presenting search histories of complex and lengthy search strategies. No single template fits all conceptualizations, but some can be applied to most processes. Database interface providers report queries as entered, not as they are actually processed. In PubMed®, the huge difference between entered and processed query is shown in “Details.” Quality control and evaluation of search strategies using a validated tool such as the PRESS checklist is suboptimal when only entry-query based search histories are applied.Conclusions: Moving toward an internationally accepted IR reporting standard calls for advances in common reporting practices. Comprehensive, process-based reporting and presentation would make IR more understandable to others than information specialists and facilitate quality control.

Abstract Objectives This article aims to provide a brief review of information retrieval and hospital-based health technology assessment (HB-HTA) and describe library experiences and working methods at a regional HB-HTA center from the center's inception to the present day. Methods For this brief literature review, searches in PubMed and LISTA were conducted to identify studies reporting on HB-HTA and information retrieval. The description of the library's involvement in the HTA center and its working methods is based on the authors’ experience and internal and/or unpublished documents. Results Region Västra Götaland is the second largest healthcare region in Sweden and has had a regional HB-HTA center since 2007 (HTA-centrum). Assessments are performed by clinicians supported by HTA methodologists. The medical library at Sahlgrenska University Hospital works closely with HTA-centrum, with one HTA librarian responsible for coordinating the work. Conclusion In the literature on HB-HTA, we found limited descriptions of the role librarians and information specialists play in different units. The librarians at HTA-centrum play an important role, not only in literature searching but also in abstract and full-text screening.

Abstract Background Managed Entry Agreements (MEAs) are increasingly used to address uncertainties arising in the Health Technology Assessment (HTA) process due to immature evidence of new, high-cost medicines on their real-world performance and cost-effectiveness. The literature remains inconclusive on the HTA decision-making factors that influence the utilization of MEAs. We aimed to assess if the uptake of MEAs differs between countries and if so, to understand which HTA decision-making criteria play a role in determining such differences. Methods All oncology medicines approved since 2009 in Australia, England, Scotland, and Sweden were studied. Four categories of variables were collected from publicly available HTA reports of the above drugs: (i) Social Value Judgments (SVJs), (ii) Clinical/Economic evidence submitted, (iii) Interpretation of this evidence, and (iv) Funding decision. Conditional/restricted decisions were coded as Listed With Conditions (LWC) other than an MEA or LWC including an MEA (LWCMEA). Cohen's κ-scores measured the inter-rater agreement of countries on their LWCMEA outcomes and Pearson's chi-squared tests explored the association between HTA variables and LWCMEA outcomes. Results A total of 74 drug-indication pairs were found resulting in n = 296 observations; 8 percent (n = 23) were LWC and 55 percent (n = 163) were LWCMEA. A poor-to-moderate agreement existed between countries (−.29 < κ < .33) on LWCMEA decisions. Cross-country differences within the LWCMEA sample were partly driven by economic uncertainties and largely driven by SVJs considered across agencies. Conclusions A set of HTA-related variables driving the uptake of MEAs across countries was identified. These findings can be useful in future research aimed at informing country-specific, “best-practice” guidelines for successful MEA implementation.

IntroductionWhen making decisions in health care, it is essential to consider economic evidence about an intervention. The objective of this study was to analyze the methods applied for systematic reviews of economic evaluations in Health Technology Assessment (HTA) and to identify common challenges.MethodsWe manually searched the webpages of HTA organizations and included HTA-reports published since 2015. Prerequisites for inclusion were the conduct of a systematic review of economic evaluations in at least one electronic database and the use of the English, German, French, or Spanish language. Methodological features were extracted in standardized tables. We prepared descriptive statistical (e.g., median, range) measures to describe the applied methods. Data were synthesized in a structured narrative way.ResultsEighty-three reports were included in the analysis. We identified inexplicable heterogeneity, particularly concerning literature search strategy, data extraction, assessment of quality, and applicability. Furthermore, process steps were often missing or reported in a nontransparent way. The use of a standardized data extraction form was indicated in one-third of reports (32 percent). Fifty-four percent of authors systematically appraised included studies. In 10 percent of reports, the applicability of included studies was assessed. Involvement of two reviewers was rarely reported for the study selection (43 percent), data extraction (28 percent), and quality assessment (39 percent).ConclusionsThe methods applied for systematic reviews of economic evaluations in HTA and their reporting quality are very heterogeneous. Efforts toward a detailed, standardized guidance for the preparation of systematic reviews of economic evaluations definitely seem necessary. A general harmonization and improvement of the applied methodology would increase their value for decision makers.

Introduction:In 2017 the Brazilian Ministry of Health (BMH), through the Department of Science and Technology (DECIT) and in partnership with the Hospital Alemão Oswaldo Cruz (HAOC), financially supported research activities focused on health technology assessment (HTA) on topics deemed important by the BMH. The aim was to help resolve the priority health problems of the Brazilian population and to strengthen the management of the Unified Health System, within the scope of HTA.Methods:A survey of HTA research needs was carried out in all BMH sectors through internal meetings conducted by representatives from each of the sectors. The problems and needs were then discussed, prioritized, and transformed into research lines in a workshop sponsored jointly by DECIT and the HAOC. Following this, a specific public call was made to the HTA community to comment on the prioritized research lines. The submitted research projects were then judged and selected by a committee of experts in the field. The approved projects were contracted, and when the projects were completed the results were presented and discussed by the researchers in a final seminar for representatives of the BMH technical areas.Results:A total of 135 research gaps were identified, of which forty-two lines of research were included in the research call after the prioritization workshop and the search for evidence in the literature. The call involved an amount of BRL one million (USD 280,442), and seventeen research projects were financed, including two systematic reviews, seven rapid reviews, and eight economic evaluations.Conclusions:The promotion of research by the BMH has enabled the search for scientific evidence to support public policies and decision making in health services.

Introduction:Health Technology Assessment (HTA) considers the question of whether evaluated technologies are cost-effective in real world settings. As observed in HTA conducted by the Australian Medical Services Advisory Committee (MSAC), questions regarding the validity of data inputs to economic analyses that reflect real-world practice is a common reason for uncertainty on the cost effectiveness of new technologies. In addition to resource use and costs, there may be other uncertainties regarding the eligible patient population, patient management pathways and comparator selection. Our objective in this study was to present case studies from Australia where real world linked datasets could be better utilized to inform HTA conducted by the MSAC.Methods:For selected therapy areas, assessment reports and public summary documents of HTA conducted by the MSAC published between January 2015 and November 2017 were reviewed. Our analysis identified HTAs where uncertainties around the inputs for health economic evaluations, as well as uncertainties in defining eligible patient numbers or current patient pathways of care were shown to exist. We then explored whether these uncertainties could have been addressed through real world linked datasets.Results:Our preliminary investigations identified two assessments: MSAC assessment of capsule endoscopy and transcatheter aortic valve implantation - where availability of real world linked data could have addressed uncertainties around the inputs required for the health economic evaluations.Conclusions:Australia has a range of real world datasets with the potential to be used to inform HTA conducted by the MSAC. This can only be achieved if the datasets could be better linked and accessible for use by key stakeholders in the MSAC HTA process (e.g. industry, clinician, patient societies). Use of these data sets in HTA will enable timelier patient access to cost-effective technologies and more effective implementation and review of technologies after adoption into clinical practice.

The Portuguese healthcare system is often portrayed as a National Health Service (NHS) model, characterized by universal coverage, comprehensive benefits, nearly free services, national tax financing, and public ownership or control of the factors of production. However, in reality the system fails to accomplish these features in a complete way. There coexist a number of occupation-related health insurance schemes that were originally intended to be integrated into the NHS. In addition, in key areas the NHS does not provide the wide range of services it promises. The public sector has a predominant role in the provision of hospital stays and general practitioner consultations, but the private sector provides a major portion of specialist consultations, dental consultations, and diagnostic services. Major problems in the system led to health reforms in the 1990s. New reform proposals include some specific steps concerning health technology, including standards for medical equipment based on quality, geographic distribution, sustainability, and cost-effectiveness. A new National Plan of Health Equipment was completed in 1998, aimed at improving the distribution of equipment. Despite reforms, healthcare expenditures continue to rise. There is general agreement that gains in efficiency could be made. This situation is beginning to encourage interest in health technology assessment (HTA) in Portugal, although these activities are not yet very developed. Recently, legislation requiring presentation of economic evaluations for new pharmaceutical products was enacted. Present plans also call for the creation in the future of a national agency for HTA.

There seems to be a general agreement amongst practitioners of economic evaluations, including Health Technology Assessment, that the explicit statement of a perspective is a necessary element in designing and reporting research. Moreover, there seems also to be a general presumption that the ideal perspective is “societal”. In this paper we endorse the first principle but dissent from the second. A review of recommended perspectives is presented. The societal perspective is frequently not the one recommended. The societal perspective is shown to be less comprehensive than is commonly supposed, is inappropriate in many contexts and, in any case, is in general not a perspective to be determined independently of the context of a decision problem. Moreover, the selection of a perspective, societal or otherwise, is not the prerogative of analysts.
