RPSGT Quality Assurance & Improvement 3

Question 1

A sleep center wants to reduce patient 'no-show' rates for overnight studies. Which QA approach is MOST systematic?

Accepted Answer

Analyze no-show data by day of week, referral source, and insurance type to identify patterns

Answer

Stratified data analysis reveals which variables most strongly predict no-shows, allowing targeted interventions rather than blanket workarounds.

Question 2

Which tool is MOST appropriate for visually displaying the frequency of different categories of PSG technical defects to prioritize QA efforts?

Accepted Answer

Pareto chart

Answer

A Pareto chart ranks defect categories by frequency, allowing a lab to focus on the 'vital few' problems that account for the majority of quality issues.

Question 3

What does 'PDSA cycle' stand for in the context of sleep lab quality improvement?

Accepted Answer

Plan, Do, Study, Act

Answer

The PDSA (Plan-Do-Study-Act) cycle is a structured quality improvement methodology used to test changes on a small scale before full implementation.

Question 4

A sleep lab tracks its artifact rate over 12 months and finds a sudden spike in Month 8. What is the BEST initial action?

Accepted Answer

Investigate what changed in Month 8 (staff, equipment, environment) to identify a cause

Answer

Identifying what specifically changed at the time of the spike (special cause variation) is essential before implementing any corrective action.

Question 5

Which AASM accreditation standard requires sleep labs to track patient satisfaction?

Accepted Answer

Quality measures and outcomes

Answer

AASM accreditation standards require labs to measure quality outcomes including patient satisfaction as part of their ongoing quality program.
