Pregledni znanstveni članek po svoji definiciji obravnava, povzema, analizira, vrednoti in sintetizirana najnovejša že objavljena dela izbranega znanstvenega področja, dela posameznega raziskovalca ali raziskovalne skupine. Priprava pregledov objav je kompleksen, obsežen in dolgotrajen postopek. Zaradi zahtevnosti pri pripravi navadno sodeluje več strokovnjakov z različnimi znanji. Priporočljivo je, da je v vlogi informacijskega specialista v proces vključen tudi knjižničar.
Postopek sistematičnega iskanja literature je sestavljen iz naslednjih korakov: načrtovanje sistematičnega iskanja literature in dokumentiranje celotnega postopka, oblikovanje jasno zastavljenega kliničnega vprašanja, določitev vključitvenih in izključitvenih kriterijev, izvedba predhodnega pregleda literature, identifikacija bibliografskih zbirk, oblikovanje iskalnega izraza iz ključnih besed, sopomenk, izrazov iz tezavra in logičnih operaterjev, optimizacija iskalnega izraza, prevod iskalnega izraza za iskanje po različnih bibliografskih zbirkah, iskanje po drugih virih, prvi izbor gradiva po pregledu naslovov in povzetkov, pridobitev polnih besedil gradiv, drugi izbor gradiv.
V prispevku korak za korakom prikazujemo načrtovanje in izvedbo poizvedbe, kot primer pa je izbrano raziskovalno vprašanje s področja onkologije, ki ugotavlja morebitno povezavo med kajenjem tobaka in rakom materničnega vratu.
Abstract (Eng)
A review article is an article in which the latest published works in a certain scientific field or the work of an individual researcher or research group are discussed, summarized, analysed, evaluated and synthesized. The preparation of reviews is complex, extensive and time-consuming. Due to this complexity, several people with different knowledge usually participate, and a librarian is also involved in the role of information specialist.
The search process consists of the following steps: plan the review and document the search process, determine a clear and focused question, develop inclusion and exclusion criteria, carry out early scoping searches, identify the specific bibliographic databases, identify key search terms, identify appropriate subject headings (index terms), synonyms and free text words, use Boolean operators, parentheses and database-appropriate field codes, optimize the search, translate the search for other databases, screen titles and abstracts, obtain full-text papers, screen the full-text papers.
As an example in practice, we will choose the planning and implementation of an inquiry in the field of oncology, which will determine the possible link between tobacco smoking and cervical cancer.
