CRE Data Analysis & Reporting 3

Question 1

A CRE is preparing a quality improvement report on inhaler technique errors. Which chart type best displays the most frequent errors in descending order?

Accepted Answer

Pareto chart

Answer

A Pareto chart ranks categories by frequency in descending order and includes a cumulative percentage line, ideal for prioritizing quality improvement targets.

Question 2

When reviewing spirometry reference equations for a 45-year-old African American female, which factor is critical to apply correctly?

Accepted Answer

Race/ethnicity-adjusted reference values

Answer

Race/ethnicity-specific reference equations are required because population-based norms differ across ethnic groups for accurate percent-predicted calculations.

Question 3

A CRE notices that asthma control questionnaire scores improved significantly in the first month but plateaued afterward. This pattern best represents which phenomenon?

Accepted Answer

Ceiling effect

Answer

A ceiling effect occurs when scores cluster near the maximum possible value, limiting the ability to detect further improvement.

Question 4

When calculating a program's COPD readmission rate, the denominator should include which patient group?

Accepted Answer

All COPD patients discharged from the hospital during the reporting period

Answer

The denominator for readmission rate includes all eligible discharged COPD patients in the period, regardless of program completion.

Question 5

A respiratory educator finds that arterial blood gas pH values in a dataset are not normally distributed. Which measure of central tendency should be reported?

Accepted Answer

Median

Answer

Median is preferred for non-normally distributed continuous data because it is not influenced by outliers or skewness.
