Using Embase as a supplement to PubMed in Cochrane reviews differed across fields.

Objective: Medline/PubMed is often first choice for health science researchers when doing literature searches. However, Medline/PubMed does not cover the health science research literature equally well across specialties. Embase is often considered an important supplement to Medline/PubMed in health sciences.

PubMed coverage varied across specialties and over time: a large-scale study of included studies in Cochrane reviews.

Objective: PubMed is one of the most commonly used search tools in biomedical and life sciences. Existing studies of database coverage generally conclude that searching PubMed may not be sufficient although some find that the contributions from other databases are modest at best. However, generalizability of the studies of the coverage of PubMed is typically restricted.

Hospital nurses' information retrieval behaviours in relation to evidence based nursing: a literature review.

Objective: The purpose of this literature review is to provide an overview of the information retrieval behaviour of clinical nurses, in terms of the use of databases and other information resources and their frequency of use.

Methods: Systematic searches carried out in five databases and handsearching were used to identify the studies from 2010 to 2016, with a populations, exposures and outcomes (PEO) search strategy, focusing on the question: In which databases or other information resources do hospital nurses search for evidence based information, and how often?

Results: Of 5272 titles retrieved based on the search strategy, only nine studies fulfilled the criteria for inclusion. The studies are from the United States, Canada, Taiwan and Nigeria.

[Systematic search for qualitative literature can be reinforced].

Finding qualitative literature is challenging and time consuming which may pose problems, as the qualitative research constitutes a significant contribution to the understanding of different aspects of health and disease. The purpose of this article was to describe the challenges of locating qualitative studies and present strategies to overcome these challenges. The cost of retrieving all the relevant literature can be a considerable amount of irrelevant hits, and the searcher must decide at which point the results are satisfying.

[Embase is a central resource for literature search in health science].

PubMed is often first choice for searching health sciences literature. However, even though Embase tends to be overlooked it is an important supplement to PubMed. The present paper provides an overview of the literature dealing with the significance of using Embase for systematic reviews and metaanalyses.

Clinical utility of F-18 FDG PET-CT in the initial evaluation of lung cancer.

Purpose: Positron emission tomography-computed tomography (PET-CT) is a resource-demanding imaging modality with increasing popularity in the workup of patients with suspected or proven lung cancer.

Methods: To review the clinical usefulness of this imaging modality in the diagnosis, staging, and pre-operative evaluation, we conducted a systematic literature search, review, and quality assessment using the rapid evidence assessment toolkit and the Oxford Centre for Evidence-Based Medicine methodology. The literature search resulted in 4,208 records including 918 reviews, of which 139 met the predefined criteria and were read in full to identify relevant original articles on F-18 FDG PET-CT (1) in the evaluation of solitary pulmonary nodules (n = 14), (2) in curative-intent treatment trials (n = 9), and (3) in planning of invasive procedures (n = 18).

HOSPITAL MANAGERS' NEED FOR INFORMATION ON HEALTH TECHNOLOGY INVESTMENTS.

Objectives: There is growing interest in implementing hospital-based health technology assessment (HB-HTA) as a tool to facilitate decision making based on a systematic and multidisciplinary assessment of evidence. However, the decision-making process, including the informational needs of hospital decision makers, is not well described. The objective was to review empirical studies analysing the information that hospital decision makers need when deciding about health technology (HT) investments.

FDG PET/CT in cancer: comparison of actual use with literature-based recommendations.

Purpose: The Region of Southern Denmark (RSD), covering 1.2 of Denmark's 5.6 million inhabitants, established a task force to (1) retrieve literature evidence for the clinical use of positron emission tomography (PET)/CT and provide consequent recommendations and further to (2) compare the actual use of PET/CT in the RSD with these recommendations.

[A guide to obtain validity and reproducibility in systematic reviews].

Validity and reproducibility are key concepts in the execution and reporting of the literature searches underlying a systematic review as it enables the reader to assess the quality of the performed searches. However, often the reporting of searches is lacking crucial information. This article provides guidelines for the process from development of a search protocol to quality assessment of the retrieved literature in order to obtain validity and reproducibility.
