8. Systematic methods should be used to search for evidence

AZQ
1.6) This question refers to the methods of searching, identifying and selecting the scientific and clinical evidence. The answer YES presupposes that search and selection strategies (e. g. computer-assisted searches and hand searches, evaluation of grey literature, e. g. unpublished research reports, conference records) should be described in detail. In addition, information should be given about the criteria used for classifying and selecting the evidence (e. g. randomised clinical trials, systematic reviews, meta-analyses, expert opinions, reports on the results of consensus conferences, and guidelines published elsewhere). 1.7) This question aims at a complete and reproducible documentation of the evidence for the statements and recommendations of the guideline. If question 1.6 (previous question) was answered NO or UNCLER, NOT APPLICABLE should be ticked off for the current question.	1.6) Diese Frage bezieht sich auf die Methoden zur Suche, Identifizierung und Auswahl der wissenschaftlichen und klinischen Belege (Evidenz). The answer YES presupposes that die Such- und Auswahlstrategien (z.B.: computergestützte Recherche, Handsuche, Auswertung grauer Literatur, z.B. nicht publizierter Forschungsberichte, von Kongressprotokollen) näher beschrieben werden. Darüber hinaus sollten Angaben zu den benutzten Kriterien zur Klassifikation und Auswahl der Evidenz vorliegen (z.B.: randomisierte klinische Studien, systematische Übersichtsarbeiten,

Current Care
Haku tehdään aina vähintään Medlinesta viimeisiltä viideltä vuodelta sekä Cochrane-kirjaston tuoreimmasta versiosta. Aiheen mukaan hakua laajennetaan. Keskeiset hakustrategiat (ainakin perushaut ja katsaushaut) tallennetaan, jotta suositusten päivitys käy mahdollisimman sujuvasti. Käypä hoito-suositusten kirjallisuushaut tehdään neljässä vaiheessa: Laaja, sensitiivinen perushaku ryhmälle. Perushakua täydentävät kirjoittajakohtaiset lisähaut. Näytönastekatsauksiin liittyvät, spesifiset katsaushaut. Vähintään kahden vuoden välein tehtävät päivityshaut.

The identification and selection of evidence is an essential step towards answering the clinical questions developed by the GDG. It is important to ensure that this process is as thorough and unbiased as possible. Searching should focus on locating the best evidence from all relevant sources - potentially, this involves extensive work. Ongoing research should also be identified as this may be important when formulating recommendations and planning updates to the guideline. The aim is to generate a comprehensive body of evidence that will: allow the clinical questions to be answered highlight any significant gaps in the evidence base where formal consensus methods may be required. The evidence used by the GDG will come from two main sources: searches of electronic databases by the technical staff at the NCC via stakeholder organisations that are invited to submit relevant information Example
SIGN
Brief details of the strategy used to search for evidence are provided in an annex to each SIGN guideline, including key search terms used, time period covered, and sources consulted. Sources may include electronic databases (e.g. MEDLINE, EMBASE, CINAHL), databases of systematic reviews (e.g. the Cochrane Library, DARE). The literature search should address each of the key questions (see item 2). More detailed information is available for some recent guidelines on the SIGN website, or on request from the SIGN Executive. Development annex Search specification
