| Popis: | Background and purpose Out-of-hospital cardiac arrest (OHCA) is one of the most common causes of death in many countries. For OHCA patients to have a good clinical outcome, bystander cardiopulmonary resuscitation (CPR) is extremely significant. It is necessary to study the various characteristics of bystanders to improve bystander CPR quality. We aimed to evaluate the correlation between bystanders' gender and clinical outcomes of patients with OHCA. Methods We conducted an observational study by using a prospective, multicenter registry of OHCA resuscitation, provided by the Korean Cardiac Arrest Research Consortium registry from October 2015 to June 2017. The following data were collected: patient's age, patient's gender, witnessed by a layperson, characteristics of the bystanders (age grouped by decade, gender, CPR education, compression method, and perception of automated external defibrillators), arrest place, emergency medical services arrival time, and initial electrocardiogram rhythms. Outcome variables were prehospital return of spontaneous circulation, survival discharge, and cerebral performance category status at discharge. Results A total of 691 patients were included in the study. There were significant differences in the initial shockable rhythm and previous CPR training between bystander's gender. Characteristics such as age, patient's gender, witnessed by a layperson, bystander's gender, initial shockable rhythm, and arrest place were significantly associated with neurologic outcome at discharge, using univariable analysis. However, in the multivariate logistic model, there was no significant correlation between bystander's gender and neurologic outcome. In the subgroup analysis using the multivariate logistic model with 291 patients without missing values of CPR education and bystander’ age, there was a significant difference in neurologic outcome depending on bystander's CPR education status. Conclusion There was no difference in the neurologic outcomes of OHCA patients based on bystanders' gender. However, according to subgroup analysis, there was a difference in the neurologic outcome depending on the status of bystanders' CPR education and females received less CPR education than males. Therefore, more active CPR education is required. |
