Question 1

A cardiac electrophysiology lab tracks its rate of vascular access complications as a quality metric. This is most accurately classified as:

Accepted Answer

An outcome measure

Answer

Vascular access complication rates reflect what happens to patients as a result of care, making them outcome measures.

Question 2

Which of the following best describes the concept of 'high reliability organization' (HRO) as applied to a cardiac intensive care unit?

Accepted Answer

An organization that operates in complex, high-risk environments yet consistently avoids catastrophic failures through specific cultural and operational practices

Answer

HROs are characterized by preoccupation with failure, reluctance to simplify, sensitivity to operations, commitment to resilience, and deference to expertise.

Question 3

The 'spec limit' concept in Six Sigma applied to door-to-balloon time in STEMI refers to:

Accepted Answer

The upper specification limit of 90 minutes defined by clinical guidelines as the performance boundary

Answer

Specification limits define the acceptable performance boundaries; in STEMI care, the 90-minute upper spec limit is set by ACC/AHA guidelines.

Question 4

A cardiac surgery program wants to compare its observed-to-expected (O/E) mortality ratio using risk-adjusted data. An O/E ratio less than 1.0 indicates:

Accepted Answer

The program's mortality is lower than expected, suggesting performance above the national benchmark

Answer

An O/E ratio below 1.0 means fewer patients died than the risk model predicted, indicating better-than-expected performance.

Question 5

In echocardiography quality assurance, 'turnaround time' from image acquisition to finalized report is monitored as a:

Accepted Answer

Process measure

Answer

Turnaround time reflects the timeliness of the reporting process and is classified as a process measure in cardiac imaging QA.
