Tools & Templates: Investigating Pandemic Risk by Determining Root Cause


This 3-page report demonstrates an appropriate and successful use of quality improvement (QI) tools in a public health setting. The document shows how an LHD used a cause and effect diagram, also known as a fishbone diagram, to drill down and find the root causes of inhibiting viral transmission in local schools with social distancing. This is an excellent resource for those looking to gain a greater conceptual understand of QI and applying it to agency functions.
