Using evidence-based medicine, research, collaboration and hard work, multiple protocols were developed and implemented by the NOTS Protocol Committee. Changes in protocols and guidelines assisted in the reduction of mortality in our community as verified by the State of Ohio Trauma Registry:

Trauma Mortality in Major Counties of Ohio

Purpose of Evaluation: This is a preliminary look at data from across the state to evaluate hospital mortality as recorded in the state trauma database*. The comparison was done between patients seen from 2006 through 2009 vs. 2010 through 2012. There has been some communication errors of this evaluation and this is to officially correct the prior communication. This first look was done to evaluate mortality of patients injured in the most populated areas. This initial analysis just includes the 5 major metropolitan areas and their respective counties. Overall statewide mortalities are also reported.

The areas included are:

  1. Cleveland - Cuyahoga County
  2. Columbus - Franklin County
  3. Dayton - Montgomery County
  4. Cincinnati – Hamilton County
  5. Akron/Canton – Summit and Stark Counties
  6. Toledo – Lucas County


  • Statewide mortality has remained similar and went from 4.5% to 4.3%.
