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 7) What aspect of the run chart helps you compare data before and after a PDSA cycle? a) The average of the values b) The baseline median c) Annotations of when specific changes were tested (PDSA cycles) d) B and C - ANSWER d) B and C 1) Which of the following is a rule for determining non-random patterns? a) A run of six points or more b) An astronomical point c) A trend of three points or fewer d) A and B - ANSWER d) A and B 2) In the above chart, how many useful observations are there? a) 27 b) 36 c) 37 d) 40 - ANSWER b) 36 3) When did a PDSA cycle occur? a) February 05 b) March 05 c) June 06 d) July 07 - ANSWER b) March 05 4) How many runs are there? a) 9 b) 10 c) 11 d) 12 - ANSWER d) 12 5) Using Rule 3, does this chart show non-random patterns? a) Yes, there are too many runs.
