http://www.cebm.net/category/ebm-resources/tools/
http://ktclearinghouse.ca/cebm
Must use the PICOT approach which requires that the framing of the research question specify the target Population, the Intervention of interest, the Comparator intervention, key Outcomes, and the Time frame over which the outcomes are assessed.
Scenario
You are the nursing representative on a working group that is providing advice to a Maternal and Child Health Centre in Melbourne on implementing a program designed to prevent infant sleep problems and postnatal depression. You volunteer to search the literature and find the following article:
Hiscock, H., Cook, F., Bayer, J., Le, H. N., Mensah, F., Cann, W., Symon, B., and St James-Roberts, I. (2014). Preventing Early Infant Sleep and Crying Problems and Postnatal Depression: A Randomized Trial. Pediatrics, 133(2), e346-e354. doi: 10.1542/peds.2013-1886
You wonder if the article is any good and whether the approach they take would be useful and suitable for your Maternal and Child Health Centre.
Introduction
There is an increasing volume of published research accessible to health professionals. With ever changing developments and new evidence it is also important to have strategies to access and interpret this material so that you can provide the best care to your patients. To ensure you that you can safely use evidence to influence your clinical decision making, you need to have skills in assessing the quality and relevance of the research you find, these skills are described as critical appraisal.
Aim
The aim of this assignment is for students to critically appraise a selected published randomised controlled trial (RCT) and to apply what is found to a clinical scenario. Students are required to complete the following activities.
• Summarise the provided study using the PICOT framework
• Critically appraise the validity of the study using an established framework
• Explain the primary study results
• Relate appraised study evidence to the clinical scenario
