For this assignment you will generate two Control Charts using QI Macros. For your convenience I have included an excel data set below which you may use to create your charts. Please create a control chart for TWO of the data elements (you may choose from among any of the options). Make sure to create labels for your chart; the automatically generated labels are not, in general, appropriate for data presentation. Along with your Control Chart construction, you will provide a brief analysis of the chart. This can take the form of a brief description of your findings (no more than a paragraph is necessary). Control Chart(s) 1. Percentage of Patient Readmissions 2.0 3.0 4.0 5.0 6.0 1 UCL 5. CL 2. Control Chart Data for Percentage of Patient Readmissions tient Readmissions The control chart above displays the percentage of patient readmission per month from January 2009 to February 2011 using IHI rules. The overall average mean for the entire data selection is 2.46% of patient readmissions, with an upper control limit of 5.25 and a lower control limit of -0.33. The control chart dislpays special cause variation in which the 1 point reaches above the UCL for June 2010 (Rule #1), followed by a trend of decreasing readmissions from June 2010 to November 2010 (rule #5).
