CMC Data Analysis & Reporting 4

Question 1

A CMC candidate reviews a study reporting p=0.04 for a new antiarrhythmic drug. What does this p-value mean?

Accepted Answer

If the null hypothesis were true, there is a 4% probability of observing results this extreme or more

Answer

The p-value is the probability of obtaining the observed data (or more extreme) assuming the null hypothesis of no effect is true.

Question 2

In cardiac imaging reporting, standardized structured reports are preferred over narrative reports primarily because they:

Accepted Answer

Improve completeness, reduce omissions, and facilitate data extraction for quality analysis

Answer

Structured reports enforce completeness by requiring all key elements, reducing variability and enabling systematic data extraction for registry submissions and quality review.

Question 3

Which measure best captures the short-term effectiveness of a rapid response team for cardiac events in a general hospital ward?

Accepted Answer

Rate of unexpected cardiac arrests outside the ICU

Answer

Unexpected cardiac arrests outside the ICU directly measure the rapid response team's ability to identify and intervene before patients deteriorate to arrest.

Question 4

A hospital notes their STEMI DTB time improved from 85 to 61 minutes after a new protocol, with p=0.001. What additional information is needed to assess clinical significance?

Accepted Answer

The effect size and whether the improvement crosses the guideline threshold of ≤90 minutes

Answer

Statistical significance alone does not confirm clinical meaningfulness; knowing whether the new time meets the ACC/AHA ≤90-minute benchmark is critical for clinical relevance.

Question 5

A quality report shows that beta-blocker prescribing at discharge for AMI patients is 94%. Which action is most appropriate?

Accepted Answer

Investigate the remaining 6% to identify contraindications versus missed opportunities

Answer

Reviewing the non-compliant cases determines whether deviations are appropriate (true contraindications) or represent improvable care gaps.
