Use the following scenario to answer questions 1-2:
During a clinical rotation on the medical-surgical floor of a hospital, you notice several patients have developed urinary tract infections (UTIs) associated with their Foley catheters (tubes inserted into the bladder to drain urine). Your staff physician agrees that this is a problem and offers to help with an improvement project. Together, you work through several PDSA cycles to reduce the rate of UTIs on your floor.
Which of the following methods would you recommend to display your improvement data? - ANS -Draw a run chart.
Run charts are an effective way to view changes over time. They are much easier to interpret visually than a list of numbers or a static display of data such as a bar chart.
When designing the run chart, it is important to include: - ANS -Units of time on the X axis
The run chart should display units of time — whether it's days, weeks, or months — on the X axis. The Y axis is where you plot the key variable you are measuring, which in this case is the rate of UTIs.
What is the minimum number of data points you should usually have to look for signs of improvement on a run chart? - ANS -10
A run chart becomes more powerful as you add more data points because there will be more opportunities to identify patterns. If you're looking for signs of improvement, usually you need at least 10 data points.
Which of the following is a problem with static data? - ANS -It doesn't adequately portray variation.
Summary statistics that are static in nature don't give you the appropriate picture of the variation that lives in your data. Although you can accurately display data such as the mean, median, or mode, it is not a good way to observe change over time.
When you are graphing a proportion or a percent, what should you look at to help you understand the bigger picture? - ANS -The denominator of the measured value
By tracking the denominator of the measured value, you can confirm that your improvement effort is really showing signs of success, and there are not other factors at work.
Within the following data set, what is the median? [2.5, 7.2, 2.5, 2.9, 4.7, 3.6, 4.7] - ANS -3.6
