ObjectivesThe presence of a bystander witness is a crucial predictor of patient survival after out-of-hospital cardiac arrest (OHCA). However, the differences in survival and neurological outcomes among different types of citizen bystanders are not well understood.DesignWe analysed data from the All-Japan Utstein Registry, a prospective, nationwide, population-based, observational study that was started in January 2005.SettingThe registry includes all patients with OHCA who were transported to the hospital by emergency medical service (EMS) in Japan. The type of citizen bystander was classified as family member, friend, colleague, passerby or other.ParticipantsWe analysed 210 642 patients in the registry who were 18 years or older and experienced OHCA of cardiac origin witnessed by a citizen bystander between 2005 and 2014.Primary and secondary outcome measuresThe main outcomes were 1 month survival and 1 month survival with minimal neurological impairment.ResultsOf the citizen bystander-witnessed cases, 65.1% (137 147/210 642) were witnessed by a family member. However, among patients who survived to 1 month and who had a favourable 1 month neurological outcome, much lower proportions (53.9% (10 907/20 239) and 48.9% (5722/11 696)) were witnessed by a family member. Witness by a friend, colleague or passerby was associated with good 1 month neurological function, after controlling for the patient’s age, first recorded rhythm, gender, bystander cardiopulmonary resuscitation (CPR), use of a public-access automated external defibrillator, dispatcher instructions, collapse-call time and response time compared with witness by a family member (friend: OR 1.35, 95% CI 1.24 to 1.46, colleague: OR 1.63, 95% CI 1.33 to 1.98, passerby: OR 1.60, 95% CI 1.39 to 1.84).ConclusionsOne-month survival and favourable1 month neurological outcome of patients with OHCA of cardiac origin witnessed by a family member were worse than those in cases witnessed by a friend, colleague or passerby, independent of the patient characteristics and the response of EMS.

Background: The 2010 guidelines have stressed that systematic post-cardiac arrest care after return of spontaneous circulation (ROSC) can improve the likelihood of patient survival with good neurological outcome. However, the 2010 guidelines showed that induced therapeutic hypothermia may be considered for comatose adult patients with ROSC after out-of-hospital cardiac arrest (OHCA) with an initial rhythm of non-shockable (Class IIb). It is unknown whether the post-cardiac arrest care for patients with non-shockable cardiac arrest contributed to favorable neurological outcome. The aim of the present study was to clarify the effects of the 2010 guidelines in patients with ROSC after cardiac arrest due to non-shockable rhythm, using the data of the All-Japan Utstein Registry, a prospective, nationwide, population-based registry of OHCA. Methods: From the data of this registry between 2005 and 2015, we included adult patients with ROSC after out-of-hospital non-shockable cardiac arrest due to cardiac etiology. Study patients were divided into three groups based on the different CPR guidelines; the era of the 2000 guidelines (2000G), the era of the 2005 guidelines (2005G), and the era of the 2010 guidelines (2010G). The endpoint was favorable neurological outcome at 30 days after OHCA. Results: The 31,204 patients who met the inclusion criteria comprised 25,045 with ROSC before arrival at the hospital and 6,259 with ROSC after hospital arrival without prehospital ROSC. Figure showed favorable neurological outcome at 30 days in the three groups. Moreover, multivariable analysis showed that the 2010 guidelines were an independent predictor of favorable neurological outcome at 30 days after OHCA, respectively (Figure). Conclusion: In the patients with ROSC after out-of-hospital non-shockable cardiac arrest, the 2010 guidelines were superior to the 2005 guidelines and the 2000 guidelines, in terms of neurological benefits.
