IHI QI:104
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.
1) Which of the following methods would you recommend to display your
improvement data?
a) Draw a bar chart.
b) Write a list of numbers.
c) Create a two-column table.
d) Draw a run chart. - Answer- d) Draw a run chart.
2) When designing the run chart, it is important to include:
a) Units of time on the Y axis
b) The rate of UTIs on the X axis
c) Units of time on the X axis
d) A and B - Answer- c) Units of time on the X axis
3) What is the minimum number of data points you should usually have to look for
signs of improvement on a run chart?
a) 6
b) 10
c) 15
d) 25 - Answer- b) 10
4) Which of the following is a problem with static data?
a) It doesn't adequately portray variation.
b) It is often inaccurate.
c) It can't display mean, median, or mode.
d) All of the above - Answer- a) It doesn't adequately portray variation.
5) When you are graphing a proportion or a percent, what should you look at to help
you understand the bigger picture?
a) The denominator of the measured value
b) The numerator of the measured value
c) The median of the denominator
d) The median of the numerator - Answer- a) The denominator of the measured
value
6) Within the following data set, what is the median? [2.5, 7.2, 2.5, 2.9, 4.7, 3.6, 4.7]
a) 2.5
b) 3.6
c) 4.0
d) 4.7 - Answer- b) 3.6
