CRE Data Analysis & Reporting 5

Question 1

A CRE reviews CPAP compliance data showing average nightly use of 4.2 hours. According to CMS criteria, this patient is considered:

Accepted Answer

Fully compliant

Answer

CMS defines CPAP compliance as at least 4 hours of use per night on 70% of nights over a 30-day period; 4.2 hours meets the nightly threshold.

Question 2

When analyzing a run chart for inhaler error rates, a signal of special cause variation is detected when:

Accepted Answer

Six or more consecutive points fall on the same side of the median

Answer

Six or more consecutive points on one side of the median (a 'run') signals non-random special cause variation in run chart analysis.

Question 3

A respiratory educator is reporting outcomes from a smoking cessation program. A 12-month biochemically verified quit rate of 22% should be compared against which benchmark?

Accepted Answer

National average cessation rates from population studies

Answer

Biochemically verified 12-month quit rates should be benchmarked against national population-level cessation data to contextualize program effectiveness.

Question 4

In reporting COPD patient education outcomes, which measure best captures the patient's perspective on impact of disease?

Accepted Answer

COPD Assessment Test (CAT) score

Answer

The CAT is a validated patient-reported outcome measure that captures the subjective impact of COPD on daily life and wellbeing.

Question 5

A CRE wants to determine whether a new asthma education intervention caused the observed improvement in control scores, rather than natural disease fluctuation. The strongest study design to confirm causation is:

Accepted Answer

Randomized controlled trial with control group

Answer

An RCT with a control group is the gold standard for establishing causation by controlling for confounders and natural disease variation.
