1 Evidence-based Practice for HINARI Users Exercises

2 (Advanced Course: Module 6)

Table of Contents:

• Evidence-based Practice definition, background and resources

• Clinical Evidence

• Cochrane Library

• EBM Guidelines

• Essential Evidence Plus

• HINARI EBM Journals

• HINARI/PubMed’s Clinical Queries

• Other Resources (including EvidenceAid)

Module Objectives:

3 The objectives of this module are to briefly summarize the concept of Evidence-based Medicine and give an overview of some of the Evidence-based health care resources in HINARI particularly those accessible via the Reference Sources drop down menu – Clinical Evidence, Cochrane Library and EBM Guidelines. The module also outlines how to locate Evidence-based health care information using the PubMed’s Clinical Queries features including ‘Search by Clinical Study Category’ and ‘Find Systematic Reviews’. The use of evidence-based information will assist clinicians and health workers in making informed decisions in the care of patients and communities.

You will need access to the HINARI to complete a series of exercises.

Exercise 1

Complete the Evidence-based Medicine Module Review. Answer the following true/false questions:

➢ Evidence-based practice mandates the application of evidence in clinical decision-making. ____true false____

➢ HINARI resources include evidence-based guidelines, articles, summaries, and systematic reviews. ____true false____

➢ Evidence-based practice requires continuous updating of one’s knowledge base. ____true false____

➢ Searching in Clinical Queries/PubMed is one of the key ways to find evaluated evidence-based summaries. ____true false____

➢ A well-done systematic review usually provides stronger evidence than a single clinical trial. ____true false____

Assignment

You have completed eleven exercises about evidence-based health care. You have read an overview article and learned how to locate information in four HINARI Reference Source, the HINARI Journals collection A-Z list and via HINARI/PubMed Clinical Queries. The final exercise was a true/false quiz about evidence-based health care. These skills will be useful to obtain evidence-based medical information and will assist clinicians and health workers in making decisions in the care of patients.
