Findings
A mobile-phone positioning system to dispatch lay volunteers who were trained in CPR was associated with significantly increased rates of bystander-initiated CPR among persons with out-of-hospital cardiac arrest.

Integration of mobile-phone positioning systems with AED registries may facilitate lay responders in locating the nearest AED and thereby increase efficacy in public-access defibrillation programs.

Almost 10,000 people voluntarily joined the program without any financial compensation, and no major adverse events were reported.

Findings
The mobile app system is highly efficient in the recruitment of first responders, significantly reducing the time to the initiation of CPR thus increasing survival rates.

Title
Real-life time and distance covered by lay first responders alerted by means of smartphone-application: Implications for early initiation of cardiopulmonary resuscitation and access to automatic external defibrillators

Authors
Angelo Auricchio, Lorenzo Gianquintieri, Roman Burkart, Claudio Benvenuti, Sandro Muschietti, Stefano Peluso, Antonietta Mira, Tiziano Moccetti, Maria Luce Caputo (May 19, 2019)

Findings
The dispatch of lay first responders directly to the OHCA site instead of first retrieving the AED, significantly decreases the time to CPR initiation.

Title
A text message alert system for trained volunteers improves out-of-hospital cardiac arrest survival

Authors
Ruud W.M. Pijls, Patty J. Nelemans, Braim M. Rahel, Anton P.M. Gorgels (June 8, 2016)

Findings
The text message alert system is effective in increasing survival to hospital discharge in OHCA victims and the degree of disability or dependence after survival is low.

Title

Findings
Digital strategies represent novel interventions to potentially improve care delivery and patient outcomes for emergency cardiovascular conditions.

Title

Findings
CPR performed before EMS arrival was associated with a 30-day survival rate after an out-of-hospital cardiac arrest that was more than twice as high as that associated with no CPR before EMS arrival.

Title
Bystander Efforts and 1-Year Outcomes in Out-of-Hospital Cardiac Arrest

Hansen, M.D., Carolina Malta Hansen, M.D., Ph.D., Kristinn Thorsteinsson, M.D., Ph.D., Shahzleen Rajan, M.D., Freddy Lippert, M.D., Fredrik Folke, M.D., Ph.D., Gunnar Gislason, M.D., Ph.D., Lars Køber, M.D., D.Sc., Kirsten Fonager, M.D., Ph.D., et al. (May 4, 2017)

Findings
Bystander CPR and defibrillation were associated with risks of brain damage or nursing home admission and of death from any cause that were significantly lower than those associated with no bystander resuscitation.

Title
Strategies to Improve Cardiac Arrest Survival: A Time to Act

Authors
Robert Graham, Chair, Mickey Eisenberg, Vice Chair (June 30, 2015)

Findings
The immediate, hands-on response of bystanders to cardiac arrest is critical to improve rates of effective resuscitation and, thereby, increase the likelihood of survival and positive neurologic outcomes for out-of-hospital cardiac arrest.

Bystander CPR makes the next link in the chain of survival, early defibrillation, more effective by increasing the proportion of individuals who are found with a shockable rhythm.

Many national and international registry studies indicate that bystander CPR can increase survival rates for OHCA between 50 and 500 percent.

Theoretically, a member of the public could be sued for providing bystander CPR; however, the committee is unaware of any successful suit of this type.

Use of PulsePoint is discussed on Pg. 160-161.
