Background
The most current objectively derived search filters for adverse drug effects are 15 years old and other strategies have not been developed and tested empirically.Objective
To develop and validate search filters to retrieve evidence on adverse drug effects from Ovid medline and Ovid Embase.Methods
We identified systematic reviews of adverse drug effects in Epistemonikos. From these reviews, we collated their included studies which we then randomly divided into three tests and one validation set of records. We constructed a search strategy to maximise relative recall using word frequency analysis with test set one. This search strategy was then refined using test sets two and three and validated on the final set of records.Results
Of 107 systematic reviews which met our inclusion criteria, 1948 unique included studies were available from medline and 1980 from Embase. Generic adverse drug effects searches in medline and Embase achieved 90% and 89% relative recall, respectively. When specific adverse effects terms were added recall was improved.Conclusion
We have derived and validated search filters that retrieve around 90% of records with adverse drug effects data in medline and Embase. The addition of specific adverse effects terms is required to achieve higher recall. 相似文献3.
Background: Search filters have been developed in MEDLINE and EMBASE to help overcome the challenges of searching electronic databases for information on adverse effects. However, little evaluation of their effectiveness has been carried out. Objectives: To measure the sensitivity and precision of available adverse effects search filters in MEDLINE and EMBASE. Methods: A case study systematic review of fracture related adverse effects associated with the use of thiazolidinediones was used. Twelve MEDLINE search strategies and three EMBASE search strategies were tested. Results: Nineteen relevant references from MEDLINE and 24 from EMBASE were included in the review. Four search filters in MEDLINE achieved high sensitivity (95 or 100%) with an improved level of precision from searches without any adverse effects filter. High precision in MEDLINE could also be achieved (up to 53%) using search filters that rely on Medical Subject Headings. No search filter in EMBASE achieved high precision (all were under 5%) and the highest sensitivity in EMBASE was 83%. Conclusions: Adverse effects search filters appear to be effective in MEDLINE for achieving either high sensitivity or high precision. Search filters in EMBASE, however, do not appear as effective, particularly in improving precision. 相似文献

Pharmaceutical interventions have brought about many benefits to health, improving the population's well‐being and life expectancy. However, these interventions are not without potential harmful side‐effects and yet searching for the evidence on adverse effects is challenging. This article summarises a PhD whose main aim was to develop a better understanding of the implications of using different sources and approaches to identifying relevant data on adverse effects. The author is Su Golder, who has recently completed her PhD at the University of York and who has already published several articles on specific aspects of her research, including this journal. This article is the first in the Dissertations into Practice series to report on a PhD study, and it summarises her research in a way which emphasises the implications for practice. AM 相似文献

Background
Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term ‘DCM’ with many overlapping keywords and numerous synonyms.Objectives
Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews.Methods
References contained within embase identified in our prior study formed a ‘development gold standard’ reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the ‘validation gold standard’.Results
A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase . We also used the ‘focus’ function to improve precision. The resulting search filter has 100% sensitivity in testing.Discussion and Conclusion
We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field. 相似文献10.

Background:Literature searches underlie the foundations of systematic reviews and related review types. Yet, the literature searching component of systematic reviews and related review types is often poorly reported. Guidance for literature search reporting has been diverse and, in many cases, does not offer enough detail to authors who need more specific information about reporting search methods and information sources in a clear, reproducible way. This document presents the PRISMA-S (Preferred Reporting Items for Systematic reviews and Meta-Analyses literature search extension) checklist, and explanation and elaboration.Methods:The checklist was developed using a three-stage Delphi survey process, followed by a consensus conference and public review process.Results:The final checklist includes sixteen reporting items, each of which is detailed with exemplar reporting and rationale.Conclusions:The intent of PRISMA-S is to complement the PRISMA Statement and its extensions by providing a checklist that could be used by interdisciplinary authors, editors, and peer reviewers to verify that each component of a search is completely reported and, therefore, reproducible. 相似文献

In reclassifying a Library and Information Science library from DDC to LC, an attempt was made to concentrate books with related subject headings on the shelf for maximum shelf retrieval even in cases where the Subject Authorities or C.I.P. assign them varying numbers. Most of the shelf concentration was achieved either by selecting a single number for a given heading and then classifying all books with the heading in that number or by replacing the standard LC number for a heading with one which placed it together with related books on the shelf. 相似文献

Searching for health information is a core activity for health library and knowledge workers, whether seeking to support health care workers in overcoming barriers to accessing drug information, exploring the potential of text mining in developing search filters, translating search filters for use on alternative databases, or the importance of updating search filters to ensure their ongoing utility. 相似文献

This article summarizes the author's dissertation regarding search strategies of millennial undergraduate students in Web and library online information retrieval systems. Millennials bring a unique set of search characteristics and strategies to their research since they have never known a world without the Web. Through the use of search engines, they have come to expect that searches can be completed using an easy, single search box that produces complete articles on just about any topic. However, the reliability and quality of much of the information on the Web is questionable. Conversely, information that resides in library information retrieval systems is often of high scholarly content, but there is not a single, user-friendly system for millennials to use. A case study investigation was conducted at the State University of New York at Oswego, a public undergraduate university in Central New York. The goal of the study was to identify the search strategies of a sampling of millennial undergraduate students in both Web information retrieval systems and library information retrieval systems in order to expand upon existing theories about millennials and to suggest interface design enhancements, which could make online library information retrieval systems easier for millennials to use. The findings recommend improving database search functionality, such as natural-language searching, spell-checking, and uniform full-text wording and placement. Results also suggested that increasing the availability of full-text articles would contribute to millennials’ use of library information retrieval systems. 相似文献
