Show me an example how this can be resolved.

The following dataset was obtained in May 2016, looking back over the previous 8 months:

Saint Barbara Medical Center - ICU CLABSIs
Period	Year	Month	No. CLABSIs	No. Line Days	CLABSI Rate/1000 Line Days
20	2015	September	10	4250	2.35
21		October	23	4150	5.54
22		November	18	5000	3.60
23		December	12	4750	2.53
24	2016	January	18	5711	3.15
25		February	19	6050	3.14
26		March	21	5700	3.68
27		April	16	4725	3.39

The ICU Director did some quick calculations, found that the unit had reduced its average CLABSI rate by almost 16%. She performed a quick regression analysis that showed that the CLABSI rates were declining and encouraged the staff that they had done very well. She forwarded all the data to the Quality Management team and asked them to confirm the excellent improvement the unit had accomplished.

As a data analyst for the Quality Management group, in order to determine if these data are different from those of the prior 19 months due to special cause (the intervention) or continue showing random, common variation effects, what analysis do you need to perform? Which analytical approach will you use and why? How will you know if the intervention performed at St. Barbara medical Center was effective in helping them reach or move toward their goal? Are there any additional analyses you would perform to help the team understand the impact of their intervention? If you have any questions or concerns about this step of the problem, contact your instructor via email to discuss. Submit your answers and rationales to the instructor.

how to show the analysis of the 27 months of data from St. Barbara Medical Center. Produce a written report showing graphically the infection results over time, changes after the intervention, and discussing whether significant movement toward their goal of a 40% reduction in CLABSIs was achieved. Comment on the reasonability of that goal, given the supporting arguments made for the elements of the intervention. Recommend next steps for the team. Include all of this in your presentation (with graphs) to the ICU team's surrogate, your instructor. Use the following structure for your work product

• Background - describe why the problem needed to be addressed
• Problem Identification and Issues Description
• Response or Strategy Chosen (includes both the work of the St. Barbara team and your work.)
• Recommendations to the St. Barbara team
