What is evidence-based lit?The evidence pyramid demonstrates types of clinical studies. Best practice is to limit to those at the top of the pyramid -- systematic reviews, meta-analyses and randomized controlled trials.

Study type Description
Systematic Review Comprehensive, methodical literature review; summarizes findings from multiple studies
Meta-Analysis Combines findings from multiple studies using statistical methods
Randomized, Controlled Trial (RCT)
Blinded clinical trial with participants randomly assigned to different groups; best study type for therapy questions*
* Note that any question best answered by a RCT may also be answered by a systematic review or meta-analysis
What is CINAHL?
• Full text articles for over 770 journals in nursing, biomedicine, alternative medicine, consumer health & allied health disciplines
• Over 3 million citations dating back to 1937

Case example #1
A 55 yo woman presents to the ED complaining of chest pain, fatigue and weakness. She is diagnosed with heart failure and prescribed a diuretic. Based on the evidence, can diuretics effectively reduce her risk of death from heart failure?
• SEARCH STRATEGYheart failure AND diuretics
• LIMIT TO– last 5 years – meta-analysis, randomized controlled trial, systematic review
Case example #2
A 35 yo man is admitted after a motorcycle accident. He is semi-conscious but having difficulties breathing on his own, so is placed on a ventilator. You are concerned about ventilator-associated pneumonia and want to know whether there are any guidelines for prevention.
• SEARCH STRATEGYventilator associated pneumonia
• LIMIT TO– last 5 years – practice guideline
Exercise #1
A 45 yo man is brought to the ED for acute alcohol withdrawal. He is prescribed benzos for withdrawal symptoms, including mild to moderate seizures. Is there any evidence that other therapies may be more effective for managing withdrawal related seizures?
For this exercise:
1. Run a search in CINAHL
2. Limit to best evidence for therapy questions
3. Select 1 result from the past 5 years
Exercise #2
A 5 yo boy with a family history of type 2 diabetes visits the clinic for immunizations. He appears healthy but ranks in the 85th percentile for weight. You are concerned he may develop diabetes and want to know if there are any guidelines for prevention in children his age.
For this exercise:
1. Run a search in CINAHL
2. Limit to practice guidelines for his age
3. Select 1 result from after 2008
