  16. 16. METHODOLOGY 16 Source:
  17. 17. Structure General search methods • Sources to search – How many sources to search? – Value of searching different sources – Value of searching for different publication types/formats – Service providers and search interfaces • Designing search strategies – Strategy development – Search filters – Other limits: language, date • Peer reviewing search strategies • Documenting and reporting search process Searching for specific aspects of HTA 1. Health problem and current use of technology 2. Description and technical characteristics of technology 3. Safety 4. Diagnostic accuracy 5. Clinical effectiveness 6. Costs and economic evaluation 7. Ethical analysis 8. Organizational aspects 9. Social aspects 10. Legal aspects 17
  18. 18. Process Two authors per chapter Chapter authors can not write appraisals for their own publications Texts prepared by non-English speakers are checked by an English speaker We try to avoid duplication of work and re- inventing the wheel 18
  19. 19. Identification of studies Use existing evidence-based and personal resources Run chapter specific search strategies in selected relevant databases Hand-searching relevant journals Set up alerts for prospective identification of evidence •Cochrane Handbook’s Searching for studies chapters •HTA Core Model handbooks •Search in the Cochrane Methodology Register •Our own reference databases •Cinahl •Embase •Lisa •Lista •Medline / PubMed •Web of Knowledge 19
  20. 20. Selection criteria Inclusion criteria Exclusion criteria 1. Duplicate publications, previous publications associated with the same study or project, and letters or comments to the editor will be linked to the related publication. 2. Individual studies or reviews presented and assessed in other evidence-based collections (such as the InterTASC Information Specialists' Sub-Group – ISSG - Search Filter Resource), will not be included. A link or a citation to the resource rather than the individual studies will then be provided. 20 1. The research question is relevant to information retrieval for HTA and the SuRe Info chapter in which it is to be included. 2. The publication provides latest evidence on a specific methodological issue. 3. The publication includes research findings of a completed scientific study (including reviews, evidence syntheses and theses). 4. The publication describes the scientific methods used in the study. 5. The research findings are still valid, i.e. have not been overtaken by technological or database changes. 6. The conclusions are supported by the presented results and the results answer the research question. 7. The results of the publication are generalizable or usable to other HTA information specialists or transferable to other projects or studies.
  21. 21. Appraisal 21
  22. 22. Category Examples of keyword A. Where the research paper explores the value of a publication type to HTA or investigates how to identify publication types one or more of the following index terms can be applied to the record. Databases, grey literature,… B. Designing strategies where the general principles are described General C. Designing strategies: specific (more than one may be applied to each record) Controlled vocabulary, keywords, proximity operators, … D. Other issues related to information retrieval research for HTA Search filters, Peer reviewing, … E. Categories reflecting the elements which may be addressed within an HTA (more than one may be applied to each record) Safety, ethics, …. F.

  29. 29. SuRe Info aims to… Contribute to an evidence-based information retrieval practice Serve as a common platform for HTA information specialists in different countries 29
  30. 30. SuRe Info is SuRe Info is not  A methods handbook  A comprehensive bibliography containing all published research evidence  An free online resource  A selection of up-to- date methods papers presented through summarized overviews 30
  31. 31. SuRe Info can be used... To keep up-to-date with information retrieval research To provide an overview of current evidence to those new to the field of information retrieval for systematic reviews and health technology assessments To find current evidence when updating search guidance of methods handbooks 31
