Different approaches can be adopted for the development of search strategies systematic reviews. The objective approach draws on already established text analysis methods developing filters. Our aim was to determine whether noninferior conceptual commonly used in Cochrane reviews (CRs).We conducted a CRs published Library. studies included were searched MEDLINE and represented total set. We then tested references previously removed could identified via approach. also reconstructed original...

Systematic literature screening is a key component in systematic reviews. However, this approach resource intensive as generally two persons independently of each other (double screening) screen vast number search results. To develop approaches for increasing efficiency, we tested the use text mining to prioritize results well involvement only one person (single study selection process.Our based on health technology assessments (HTAs) drug and non-drug interventions. Using sample size...

In the development of search strategies for systematic reviews, "conceptual approaches" are generally recommended to identify appropriate terms those parts which no validated filters exist. However, "objective based on identified by text analysis increasingly being applied.To prospectively compare an objective with a conceptual approach strategies.Two different MEDLINE were developed in parallel five reviews covering range topics and study designs. The Institute Quality Efficiency Health...

A retrospective analysis published by the German Institute for Quality and Efficiency in Health Care (IQWiG) 2018 concluded that no filter non‐randomized studies (NRS) achieved sufficient sensitivity (≥92%), a precondition comprehensive information retrieval. New NRS filters are therefore required, taking into account challenges related to this study type. Our evaluation focused on development of with control group (“controlled NRS”), as type allows calculation an effect size. In addition,...

The identification of health services research in databases such as PubMed/Medline is a cumbersome task. This task becomes even more difficult if the field interest involves use diverse methods and data sources, case with nurse staffing research. type investigates association between parameters nursing patient outcomes. A comprehensively developed search strategy may help identify PubMed/Medline. set relevant references was identified by means three systematic reviews. development used to...

Little evidence is available on searches for non-randomized studies (NRS) in bibliographic databases within the framework of systematic reviews. For instance, it currently unclear whether, when searching NRS, effective restriction search strategy to certain study types possible. The following challenges need be considered: 1) controlled trials (NRCTs): whether they can identified by established filters randomized (RCTs). 2) other NRS (such as cohort studies): exist each type and, if so,...

The history of European health technology assessment (HTA) goes back more than 30 years. Almost as old HTA agencies themselves is the desire to achieve collaboration. This gained further impetus with establishment Network Health Technology Assessment (EUnetHTA) in 2006. In this context, field information management faced specific challenges. Although these services are an integral part and specialists play a key role here, often not adequately represented within EUnetHTA. Furthermore,...

Abstract Objectives: National databases may be useful sources in the production of a systematic review (SR). The aim this study was to assess potential benefit search German database ‘Current Contents Medizin’ (CCM ed ). Methods: conducted on basis published SRs that included CCM as literature source. Eligible were identified through medline , embase and Cochrane Library. websites Health Technology Assessment agencies also screened. Citations primary studies relevant extracted then...

Systematic information retrieval generally requires a two-step selection process for studies, which is conducted by two persons independently of one another (double-screening approach). To increase efficiency, methods seem promising, will be tested in the planned study: use text mining to prioritize search results as well involvement only person study (single-screening The aim present examine following questions related selection: Can Rayyan or EPPI Reviewer tools efficiency? How accurately...

Abstract Introduction One of the main tasks in information retrieval is development Boolean search strategies for systematic searches bibliographic databases. This includes identification free‐text terms and controlled vocabulary. IQWiG has previously implemented its objective approach strategy using a fee‐based text analysis software. However, this implementation not fully automated, due to lack technical options. The aim our project was develop tool R. Methods We adopt an incremental...
