Which statistical process control chart is most appropriate for monitoring the proportion of defective echocardiographic studies requiring repeat acquisition?
Answer: p-chart
The p-chart monitors the proportion (or percentage) of nonconforming units in a sample, making it ideal for tracking defective study rates.
In a cardiac catheterization laboratory, the PDSA cycle stands for:
Answer: Plan-Do-Study-Act
PDSA (Plan-Do-Study-Act) is a foundational quality improvement framework used to test and implement changes iteratively.
A hospital's door-to-balloon time for STEMI exceeds the 90-minute benchmark. Which tool best identifies the root cause of the delay?
Answer: Fishbone (Ishikawa) diagram
A fishbone (Ishikawa) diagram systematically categorizes potential causes of a problem across multiple domains (people, process, equipment, etc.).
The concept of 'failure mode and effects analysis' (FMEA) in cardiac care primarily serves to:
Answer: Prospectively identify and prioritize potential process failures before they cause harm
FMEA is a proactive risk assessment tool that identifies potential failures and their impacts before an adverse event occurs.
Which of the following is a key principle of the Lean methodology as applied to a cardiac imaging department?
Answer: Eliminating waste and non-value-added steps in workflow
Lean methodology focuses on identifying and eliminating waste (muda) to improve efficiency and value delivery to the patient.
In echocardiography QA, interobserver variability is best assessed by:
Answer: Comparing two readers' measurements of the same study using intraclass correlation coefficient (ICC)
The intraclass correlation coefficient (ICC) quantifies agreement between two or more raters measuring the same continuous variable on the same subjects.
Which of the following best defines a 'sentinel event' in the context of cardiac quality assurance?
Answer: An unexpected occurrence involving death or serious physical harm requiring immediate investigation
A sentinel event is an unexpected occurrence resulting in death, serious physical or psychological injury, or the risk thereof, triggering a root cause analysis.
