“…In previous studies, the BCPR variable has been analysed by categorizing whether it was prompted by the DA or spontaneously performed before without DA prompting. 29 , 30 , 31 However, it was difficult to conclude the effect of DA-CPR because a similar categorisation would result in a second complete separation in this study.…”

“…Previous studies reported better neurological outcomes with DA‐CPR versus without bystander CPR, 4–6,8 but the patients included in those studies differed. Some studies only included patients with witnessed cardiac arrest, 4–6 and the other only included children 8 . The results of the current study suggest that the effectiveness of CPR instructions is dependent on the presence of a witness.…”

“…Consequently, the importance of bystander CPR is recognized worldwide and the clinical guidelines in many countries recommend that dispatchers provide CPR instructions to the bystander 2,3 . Although CPR instructions provided by a dispatcher do not always result in CPR being performed, bystander CPR performed as a result of CPR instructions provided by a dispatcher (i.e., dispatcher‐assisted CPR [DA‐CPR]) was associated with better outcomes in patients with witnessed and suspected cardiogenic OHCA 4–6 . However, the effectiveness of CPR instructions by a dispatcher has not been fully examined.…”

AimTo determine whether dispatcher‐provided cardiopulmonary resuscitation (CPR) instructions improve the outcomes of out‐of‐hospital cardiac arrest (OHCA).MethodsCases registered in the Japanese Association for Acute Medicine Out‐of‐Hospital Cardiac Arrest (JAAM‐OHCA) Registry between June 2014 and December 2019 were included. Cases in which the dispatcher provided CPR instructions to the bystander were included in the “Instructions” group”, and cases without CPR instructions were included in the “No Instructions” group. The primary outcome was the proportion of patients with a favorable neurological outcome, defined as a Glasgow–Pittsburgh cerebral performance category scale of 1 to 2 at 1 month after OHCA.ResultsOverall, 51,199 patients with OHCA were registered in the JAAM‐OHCA Registry during the study period. Of these, 33,745 were eligible for the study, with 16,509 in the Instructions group and 17,236 in the No Instructions group. The proportion of patients with a favorable neurological outcome at 1 month after OHCA was inferior in the Instructions group than in the No Instructions group (2.3% versus 3.0%, p < 0.001). After adjustment for patient background characteristics, no association was found between CPR instructions provided by a dispatcher and favorable neurological outcomes at 1 month after OHCA (adjusted odds ratio, 1.000; 95% confidence interval, 0.869–1.151, p = 0.996).ConclusionThe present study found no clear clinical benefit of dispatcher‐provided CPR instructions on the neurological outcomes of cases with OHCA.

High death rates in out-of-hospital cardiac arrest are mainly associated with failure of bystanders to provide lifesaving help before arrival of medical professionals. This constitutes a major problem for present-day Russia and determines the urgent need to take managing measures aimed at maximizing involvement of the lay public into the process of resuscitation and first aid provision. Based on an analysis of contemporary scientific literature, this paper provides a justification for creation and implementation of a unified coordinated program of dispatcher-assisted cardiopulmonary resuscitation (DA-CPR), when dispatchers of emergency services provide witnesses of cardiac arrest with instructions on how to perform resuscitation over the telephone in Russia. In particular, the article describes the foreign experience of implementation of DA-CPR programs that confirms a high effectiveness of the dispatcher support as it applies to outcomes of out-of-hospital cardiac arrest; it discusses a place of DA-CPR in current international guidelines on management of cardiac arrest; and it gives an analysis of managing and legal prerequisites for implementation of DA-CPR into the daily work of emergency medical services and 112-emergency system in Russia, including the existing dispatching infrastructure for implementation of the DA-CPR program, and current legal framework that regulates management and operation of the emergency services that provide remote consultations on health protection for the public. Based on the analysis, priority managing measures were identified aimed at effective and unified implementation of the DA-CPR in Russia. For relevant literature, we searched Medline, Scopus, Web of Science, Google Scholar and Russian Science Citation Index.
