1 Challenge #6: There are 2 main points of concern when evaluating EM data that may indicate something is going on in your manufacturing environment:
1. A change in numbers
2. A change in species
Click on Tracking & Trending to investigate.
2 A basic indicator for changes is a change in the ration between Gram positive and Gram negative isolates over time. Click on "Bacteria by Gram Reaction."
3 The report will default to the previous 3 months, but we would like to choose a different time frame. Click on the "Options" icon.
4 Change the Start Date to 2016-03-01 and the End Date to 2016-06-01 to review Gram reaction during this time frame. Click "OK."
5 Note the results:
86% Gram positive
11% Gram negative
6 Take a look at a different time frame by clicking on the "Options" icon.
7 Choose the time frame from 2017-01-01 to 2017-03-01.
8 Click "OK" to review the results of the Gram reaction report with new inputs.
9 Note the results:
35% Gram positive
65% Gram negative
10 Where does this higher number of Gram negative come from? Possibly a water issue? Click on the "Negative" pie piece to learn more.
