The Cook County Trauma & Burn Unit (CCTBU) supports public safety professionals in their mission to protect our nation! In doing so, the Trauma & Burn Unit directly supports operations and training for many law enforcement and EMS agencies in the Chicago Region. This includes the Maintainence of the Cook County Mobile Field Assistance and Support Team (M-FAST). This entity represents interagency cooperation between the Cook County Health and Hospital System (CCHHS), the Cook County Sheriff’s Office (CCSO) and the Cook County Departments of Homeland Security and Emergency Management (DHSEM). M-FAST creates the umbrella by which the following entities are able to operate.

LEMATOperational Support

Law Enforcement Medical Asset Team (LEMAT): Tactical medical support is provided for several regional law enforcement agencies in conjunction with the Cook County Sheriff’s Office, the Northern Illinois Police Alarm System as well as the Illinois Law Enforcement Alarm System. Through the Sheriff’s Office, any regional agency may request operational medical support that, after approval, will result in the dispatching of the necessary medical operational assets.

Training Partnerships

The CCTBU, in conjunction with Rush University, provides monthly training in the simulation lab. Law Enforcement paramedics and EMTs form various agencies regularly train together on advanced techniques, scenarios and lectures in the lab. It is common that officers from regional agencies and teams will have to work together in the field. This monthly training opportunity serves to enhance collaboration by forming relationships founded in experience and reality based training. This state of the art simulation lab experience is frequently move out to the field to further enhance the reality based experience. All training activities are overseen by the attending staff at the CCTBU and the various agency team leaders.

In addition to the SWAT medics, the simulation lab opportunity is regularly extended to non-medic line level officers and agents in order to foster and promote self aid buddy aid (SABA) and medical tactics training. Through this experience, we have identified benchmarks for proficiency in order to develop a minimum local training standard. The training partners include:

  • Cook County Sheriff’s Office
  • Northern Illinois Police Alarm System
  • Illinois State Police
  • United States Drug Enforcement Agency
  • Federal Bureau of Investigation
  • South Suburban Emergency Response Team
  • Chicago Police Department
