a) it enables users to conduct a narrow search on clinical questions
b) it enables users to conduct a broad search on clinical questions
c) it enables users to search by clinical study type - e.g. prognosis or diagnosis

d) it links patient characteristics with evidence to provide clinical decision support
If you are searching the cochrane database of systematic reviews, you are searching for evidence from which level of the 6s pyramid?
a) synopses of studies
b) summaries
c) synopses of syntheses
d) syntheses
d) syntheses
Medline uses MeSH (medical subject headings), CINAHL uses CINAHL subject headings and EMBASE uses Emtree. These are examples of:
a) index terms
b) synonyms
c) text words

Q7 emailing alerting services su h as those offered through Evidence Updates are a form of ‘pull’ information delivery.
a) True
a) False
a) False
google scholar is a good place to begin you up search for research evidence
a) True
b) False
b) False
More: you should always begin your search as high up the pyramid of evidence as possible. This usually means at a level of systems, summaries, synopses of syntheses or syntheses, depending on the profession and/or clinical question. There are more efficient resources (as described in chapter 3) to search in to find these types of evidence than on google, particularly if your question is about intervention effectiveness.
The words ‘AND’ and ‘OR’ can be used either to narrow or to broaden a search strategy. These two words are better known as:
a) Boolean operators
b) limiting operators
c) variant operators
d) truncating operators
a) Boolean operators
EBP has 5 steps. What are they?
1) Convert your information needs into an answerable question.
2) Find the best evidence to answer your clinical question
3) Critically appraise the evidence for its validity, impact, and applicability
4) Integrate the evidence with clinical expertise, the patients values and circumstances and information from your practice context
5) Evaluate the effectiveness and efficiency with the process that was carried out and think about ways to improve your performance next time
More: also known as the the 5 A’s - ask a question, access the information, appraise the articles found, apply the information and audit
The process of EBP removes the need for a healthcare professional to rely on their own clinical judgement when making decisions for patients.
a) True
b) False
a) False
More: healthcare professionals are required to incorporate research evidence, information from then practice context, patient values and circumstances and clinical experience into the process. Chapter 1 of the textbook has a more detailed discussion on this topic.
The “research evidence” component of the EBP model must only include quantitative studies.
a) True
b) False
b) False
More: research evidence is one component of the EBP model, however it is notonly limited to quantitative study designs. Chapter 1 of the textbook outlines this topic in more detail.
Briefly outline the definition of EBP
?EBP is any practice that relies on scientific evidence for guidance and decision making.
More: see the online package from week 1 and chapter 1 of the textbook for a discussion on this topic. “The practice of evidence based medicine means integrating individual clinical expertise with the best available external evidence from systematic research. By individual clinical expertise we mean the proficiency and judgement that individual clinicians acquire through clinical experience and clinical practice. Increased expertise is reflected in many ways, but especially in more effective and efficient diagnosis and in the more thoughtful identification and compassionate use of individual patients predicament, rights and preferences in making clinical decisions about their care.
You are interested in identifying the most effective Treatment strategy for a patient. What study designs is the lowest on the evidence pyramid?
a) critically-appraised individual articles (article synopses)
b) background information / expert opinion
c) cohort studies
d) critically appraised topics (evidence syntheses)
e) case-controlled studies, case series / reports
b) background information / expert opinion

Differentiate between push and pull information and explain which type of information is most likely to assist you to adopt an EBP approach.
?Push = provider putting pressure/demand onto the consumer.
?Pull = consumer putting pressure/demand onto the provider.
