Question 211

A home health agency's Performance Improvement Committee has decided to base staff educational programs on aggregated occurrence report data. Due to budgetary and time constraints, not every area identified from the data can be addressed.
Which of the following would be most useful to the committee in determining their educational targets?

A.force field analysis
B.control chart
C.Pareto chart
D.scattergram

Question 212

The primary benefit of adopting a countrywide or global uniform set of discharge data is to:

A.Assist medical records personnel in collecting internal data
B.Facilitate collection of comparable health information
C.Facilitate computerization of data
D.Validate data being collected from other sources

Question 213

The control chart above indicates which of the following?

A.Common cause variation
B.Special cause variation
C.Unique cause variation
D.No variation

Correct Answer: B

* Understanding Control Charts and Variation TypesControl charts are used to monitor process stability over time by identifying different types of variation. Variations on a control chart can generally be categorized as:
* Common Cause Variation: Random variation that is inherent to the process, typically within control limits.
* Special Cause Variation: Variation that is unusual, not inherent to the process, and suggests an external factor or a change in the process.
* Unique Cause Variation: This term is not commonly used in statistical process control; it likely refers to a special or unusual cause.
* No Variation: Indicates a completely stable process with no changes over time, which is rarely the case in practice.
* Interpreting the Control ChartThe control chart shows the rate of restraint hours per 1000 patient hours over time. Key indicators of special cause variation include:
* Data points outside the control limits (Upper Control Limit and Lower Control Limit).
* Patterns, such as runs of data points above or below the mean, or sudden shifts and spikes in data.
In this chart, we see several spikes (particularly in July and September of 2013 and again in October 2014) that reach or exceed the upper control limit. This suggests that certain events or changes in these periods caused the restraint hours to increase significantly, which is not due to the inherent process variation.
* Conclusion for the Correct AnswerSince the chart displays data points that go outside the control limits and exhibit unusual patterns, it is indicative of Special Cause Variation. This suggests external factors or specific changes in the facility process during those periods that require further investigation to determine the cause of the spikes.
