简要总结
The investigators hypothesized that pre-arrival instructions would increase the likelihood of bystanders performing Cardiopulmonary Resuscitation (CPR).
详细描述
The City of Milwaukee and surrounding communities combine to form Milwaukee County covering 241 square miles and serving approximately 959,521 people. Milwaukee County includes 19 separate municipalities. Community demographics and other characteristics have remained largely stable for the past decade.
The study will take place in Milwaukee County from 2009 - 2013 in the communities providing Cardiopulmonary Resuscitation (CPR) pre-arrival instructions: West Allis and Oak Creek.
In Milwaukee County Basic Live Support (BLS) shall be started on all patients in cardiac arrest with the exception of victims with: decapitation; rigor mortis; evidence of tissue decomposition; dependent lividity; presence of a valid Do-Not-Resuscitate (DNR) or Physician Orders for Life-Sustaining Treatment (POLST); fire victim with full thickness burns to 90% or greater body surface area; hypothermic patients with signs of frozen tissue, rigid airway, ice formation in mouth, or chest noncompliant for Cardiopulmonary Resuscitation (CPR). The system standard is: Cardiopulmonary Resuscitation (CPR) will be provided whenever patient is pulseless; compressions at least 100/minute; hands on chest more than 75% of time; minimum compression depth of 2 inches in adults 75% of the time.
Therefore, the investigators will analyze data to assess how Cardiopulmonary Resuscitation (CPR) pre-arrival instructions may have affected the probability of receiving bystander Cardiopulmonary Resuscitation (CPR).
