SYSTEMATIC LITERATURE REVIEWS OF MEDICAL DEVICES

SUMMARY : WHAT HAS BEEN COVERED

Search using Subheadings

• Four new subheadings for medical devices added in 2014

• Disease subheading ‘complication’ available for older records

• Additional results are retrieved using Emtree terms / keywords

Medical Devices on Embase

• More medical device terminology, now with over 3,000 terms

• Device trade names in Emtree, now with over 1,000 synonyms

• Device Search / Search filters for easy access to the most relevant information

Systematic Reviews

• Search for systematic reviews using EBM limits and index terms

• Search for primary studies using PICO to identify relevant studies

• Diagnostic tests: identify key results using ‘diagnostic test accuracy study’
