Assignment - Finding evidence & exploring the literature
This assessment is based on the content that was covered in units 1 (The nature of research and evidence) and 2 (Finding evidence & exploring the literature) of Research in community health. It asks you to demonstrate your ability:
• to construct and recognise different types of clinical questions;
• to search and select research articles that best answer clinical questions;
• to describe the position of different research articles on the hierarchy of evidence.
Question 1:Clinical question formulation
i. Construct a foregrounded and answerable clinical question of your choice.
ii. Put you foregrounded clinical question into the PICO format (or any appropriate format, e.g.: SPIDER) and describe what type of question it is (e.g.: intervention, prognosis). For example:
Intervention question: In the elderly, does Tai Chi reduce the risk of falls?

risk reduction
|
Question 2: Search strategy i. Construct a search strategy for a subscription database (e.g.: MEDLINE, CINAHL) to find articles (published research) that answer your question. You must find 1 example of filtered evidence (e.g.: Systematic review) and 1 example of unfiltered evidence (e.g.: RCT).
ii. Present the search strategy so it could be replicated by another researcher. For example:
Keywords → 1. 'tai chi' OR taichi OR 'tai ji quan'
Subject heading → 2. Martial arts/
Boolean operator → 3. 1 AND 2
4. 'risk reduction' OR 'reduction of risk' OR 'occur* of risk'
5. Health Statistics/ OR Epidemiology/
6. 4 AND 5
7. 3 AND 6
Filter → 8. Limit 7 to elderly
9. Limit 8 to systematic review
Question 3: Retrieval and citation
i. Download PDFs of the 2 articles you have found and attach them to your assessment.
ii. Give the citations of your 2 articles in APA 6 format.
For example:
Smith, G., Cowan, O., Xin, M. 2017. Health benefits of 3 different Chinese martial arts in the elderly. A systematic review and meta-analysis.
Lancet, 3 (6), 104-108. doi: 10.1017/S147
iii. Where are the 2 selected studies situated on the hierarchy of evidence?
