Arizona Prehospital CPR Quality Improvement Project

Phase I: In the first phase of the project, the EMS systems will utilize the E-series units to treat all patients with OHCA. The audiovisual feedback prompts will be inactivated during this phase. The EMS providers will be instructed to follow the standard CCR protocol, as is currently the practice. Aside from the change in monitor/defibrillator equipment, the treatment of OHCA patients during this phase will be identical to the treatment that is currently performed. The quality of CPR will be measured using the accelerometer-based system. The data will be stored in the defibrillator and will be downloaded upon completion of the call. The first phase will be conducted for approximately 6 months from the time each site initiates the use of the E-series monitor/defibrillators. Phase 2:In the second phase of the project, the EMS providers will undergo training on how to use the audiovisual feedback prompts. The providers will continue to treat patients according to the CCR protocol but will now receive audio and/or visual feedback on the quality of CPR that they are performing. The providers will select the preferred feedback method(s) - audio, visual or both. As in phase I, the CPR data will be stored in the defibrillator and will be downloaded upon completion of the call. The total number of EMS personnel who will be trained is approximately 450. In Phase I, there were 219 OHCAs (80% from Mesa Fire Dept, and 20% from Guardian Medical Transport). So far in Phase II, there have been about 100 OHCAs.
