OEC Research Methods & Evidence-Based Practice 3

Question 1

A ski patrol team wants to evaluate whether a new traction splint reduces patient pain scores compared to a standard splint. Which study design is most appropriate?

Accepted Answer

Prospective randomized controlled trial comparing the two splints

Answer

A prospective RCT with random assignment to each splint type is the most rigorous design to compare the two interventions.

Question 2

What is 'publication bias' and why does it matter in evidence-based practice?

Accepted Answer

The tendency for journals to publish only studies with positive or significant results, skewing the evidence base

Answer

Publication bias occurs when studies with positive results are more likely to be published, making an intervention appear more effective than it truly is.

Question 3

In an OEC research context, what does 'blinding' a participant mean?

Accepted Answer

Keeping the participant unaware of which treatment group they have been assigned to

Answer

Blinding keeps participants unaware of their group assignment to reduce placebo effects and response bias.

Question 4

Which of the following best describes a cohort study?

Accepted Answer

A group of individuals sharing a common characteristic is followed over time to observe outcomes

Answer

A cohort study follows a defined group (cohort) over time, observing who develops the outcome of interest.

Question 5

An OEC protocol update states it is based on a 'Grade A recommendation.' What does this grade typically indicate?

Accepted Answer

There is good evidence from well-designed studies to support the recommendation

Answer

Grade A recommendations are typically supported by consistent, high-quality evidence such as multiple well-designed RCTs.
