Question 1

Which QI methodology uses a structured problem-solving approach with eight specific steps including defining the problem, analyzing root causes, and verifying solutions?

Accepted Answer

Eight Disciplines (8D)

Answer

The 8D (Eight Disciplines) methodology provides a structured eight-step team-based problem-solving approach commonly used in healthcare quality improvement.

Question 2

A hospital wants to reduce catheter-associated urinary tract infections (CAUTIs). Which tool would BEST help the QI team identify and visualize all potential contributing factors?

Accepted Answer

Fishbone diagram

Answer

A fishbone (Ishikawa) diagram is used to systematically identify and organize potential root causes of a problem across categories such as people, process, equipment, and environment.

Question 3

In statistical process control, a process is considered 'in control' when:

Accepted Answer

All data points fall within three standard deviations of the mean with no non-random patterns

Answer

A process is in statistical control when all variation is due to common cause variation, evidenced by data points within control limits and no non-random patterns (runs, trends, etc.).

Question 4

The IHI Triple Aim framework focuses on three simultaneous goals. Which combination correctly represents these goals?

Accepted Answer

Population health, patient experience, and per capita cost

Answer

The IHI Triple Aim addresses improving the health of populations, enhancing the patient experience of care, and reducing the per capita cost of healthcare.

Question 5

Which statistical test is most appropriate for analyzing whether a QI intervention significantly changed a continuous outcome variable measured before and after in the same patient group?

Accepted Answer

Paired t-test

Answer

A paired t-test compares means from the same group measured at two time points, making it appropriate for pre-post intervention studies with continuous normally distributed data.
