What is a Run Chart?A run chart is a graphical display of data plotted in some type of order, that includes a central tendency.

The horizontal (x) axis is usually a time scale.The vertical (y) axis is the quality indicator studied.Source: Perla et al. 2011. The run chart: A simple analytical tool. D M A I C

Why Use Run Charts?Make process performance visibleAnalyze data for patterns (signals)Determine if changes we make result in improvementSource: Perla et al. 2011. The run chart: A simple analytical tool

Consequences of not understanding variationSee trends when there are no trends.Blame or give credit for things that are not in our controlCreate a negative work climateYou will not be able to understand past performance or make predictions about future performanceD M A I C

How do we know that a change is improvement? For data over time, run charts and control charts are the best tools to determine if our improvement strategies have the desired effect.D M A I C

Introduction to Control Charts

D M A I C

Run Charts vs. Control ChartsRun charts are not Control charts.Common cause vs. special cause variationRun charts cannot determine if the process is stable.Source: www.au.af.mil/au/awc/awcgate/navy/bpi_manual/runchart.pps D M A I C

Types of VariationCommon CauseInherent in the processDue to regular or natural causesAlso known as random variationSpecial CauseIs due to irregular or unnatural causes that are not inherent in the design of the processResults in unstable process that is not predictableAlso known as non-random variationD M A I C

TBI QI STUDYGOAL: To determine adherence to an existing COA algorithm and guideline for management of TBI patients in the COA pediatric ICU. We will also identify and explore opportunities for more standardized care to improve both process and outcomes in pediatric TBI patients. D M A I C

We are interested in how well COA adheres to the Pediatric Severe TBI management algorithm which is seen here.

45

D M A I C

It is supported by literature (BTF/brain trauma foundation guidelines, but not cited) but its also a rather complicated one and we believe that we have room for improvement at COA through more standardized care. Were also looking for ways to identify ways we can improve outcomes in severe pediatric TBI patients in this study.

D M A I C

Out of 27 total responses you can see the breakdown of job titles here the self-reported average familiarity with the algorithm was 7.18/10 and an initial estimated compliance of 72.64% which is pretty much equivalent to the 7.18 familiary rating. Then I actually asked you a question about the algorithm: which day do you want to start feeds? 60.71% of you answered correctly day 2, which is a little less than the self-reported average familiarity w/ the algorithm of 7.18/10. Then after trying to cast doubt about your knowledge regarding the TBI algorithm, I asked you again and your estimated % compliance fell steeply to 69.25%. Not significant. It was a difference of about 3%. So it seems that from the survey, we got that our team slightly overestimates its familiarity with the TBI protocol and that the opinion is pretty stable.

MD (Fellows, Attendings) familiarity ratings was 8. Compliance before: 66.36; after: 57.73%% correctly answered Day 2: 63.64%48

ComplianceD M A I C

Before I show you our results, I want to define compliance. We defined it as the % of the time where we met our 10 goals of management from the algorithm, 49

which are listed on the left. Now some other key elements that we looked at are listed on the right but actually I would like to focus todays talk on the 10 on the left. To determine compliance, I asked for each of the 10 elements, how often were we compliant with the guidelines. 50
