Which statistical tool is most appropriate for tracking the number of defects per patient education session over time?
Answer: c-chart
A c-chart (count chart) is used to monitor the number of defects or nonconformities in a constant-size sample over time.
In a respiratory therapy department's QI initiative, the Plan-Do-Study-Act cycle's 'Study' phase primarily involves:
Answer: Analyzing data collected during the trial run
The Study phase involves analyzing the results of the small-scale test to determine whether the change produced the desired improvement.
A respiratory educator notices that inhaler technique errors cluster around a specific step. Which QI tool best visualizes the frequency of different error types in rank order?
Answer: Pareto chart
A Pareto chart ranks categories by frequency, helping identify the 'vital few' causes responsible for the majority of errors.
Which measure of central tendency is MOST resistant to extreme outlier values when evaluating patient satisfaction scores?
Answer: Median
The median is resistant to outliers because it represents the middle value of a dataset regardless of extreme scores.
When a respiratory education program reviews sentinel events, the primary goal is to:
Answer: Identify systemic factors that contributed to the event
Sentinel event reviews use root cause analysis to identify system-level factors so that similar events can be prevented in the future.
A hospital implements a new asthma action plan protocol. Six months later, ER revisit rates drop. This is an example of measuring which type of quality indicator?
Answer: Outcome indicator
Outcome indicators measure the end result of care delivery, such as changes in patient health status or utilization rates.
In the context of respiratory education QI, 'benchmarking' refers to:
Answer: Comparing performance against best-practice standards or top-performing peers
Benchmarking involves comparing an organization's performance metrics against recognized leaders or best-practice standards to identify improvement gaps.
