BackgroundWe aimed to determine the incidence of and associated risk factors for cardiopulmonary resuscitation (CPR)‐related injuries in non‐survivors of out‐of‐hospital cardiac arrests (OHCAs) in an emergency medical service (EMS) system in which all CPR procedures are performed on scene and patients are not routinely transported to the hospital with ongoing CPR.Material and methodsWe conducted this prospective observational study between 1 June 2013, and 31 May 2014. Data were collected from EMS datasheets and forensic autopsy records. The exclusion criteria were OHCAs due to trauma in the thoracic or abdominal area. EMS adhered to the European Resuscitation Council Resuscitation Guidelines (2010) during the resuscitation attempts.ResultsEmergency medical service provided CPR in 280 attended OHCAs with 207 cases terminated on scene. A total of 149 patients underwent a forensic autopsy and 47% had a CPR‐related injury. The most common injuries were multiple rib fractures (43%), with 22% of patients having more than eight fractured ribs. Abdominal visceral injuries or injuries related to airway management were rare. The injuries were associated with older age, male gender, initial shockable rhythm and public location of the cardiac arrest (P < .05 respectively). In the multivariable regression analysis, older age, male gender, and public location were independent predictors for injuries. There were no differences in the durations of the CPR attempt between the injured and non‐injured groups.ConclusionOlder age, male gender, and public location were independently associated with CPR‐related injuries. The duration of the resuscitation attempts did not affect the incident of injuries.
