Chest compression is performed mainly through flexion and extension of the hip joint while kneeling on the floor and through the elbow and shoulder joints while standing in a moving ambulance. Therefore, the low quality of chest compression during ambulance transportation may be attributable to an altered technique of performing the procedure.
Two call triage protocols have almost the same predictability as the Medical Priority Dispatch System (MPDS). The study indicates that CFR protocol Ver.1 is better than CFR protocol Ver.0 because of the higher predictability and low number of activations. Also, it indicates that CFRs who are not medical professionals can respond to a patient with cardiac arrest.
We constructed a prototype community first responder (CFR) dispatch system. The system sends incident information, including a map, to the chosen CFR's mobile phone. We tested it in a simulation of 30 out-of-hospital cardiac arrest incidents which had occurred in the town of Motegi during the previous year. Thirty off-duty firefighters acted as CFRs and were sent to the same locations. The mean response time (from the CFR receiving dispatch information to arrival at the scene) was 3 min 37s faster than the actual response time in the corresponding historical control, i.e. the response time was reduced by 36% (P < 0.01). The median travel distance of the CFRs was 3.4 km and there was a positive correlation between response time and travel distance. The study showed that interactive communication between dispatcher and CFR was important for effective operation and that CFRs could reach an OHCA patient before the Emergency Medical Service arrives.
BackgroundTo improve out-of-hospital cardiac arrest (OHCA) survival rates in Japan, implementation of a community first responder (CFR) system is considered one of the most effective emergency medical service options. We investigated the possibility of introducing a CFR system in Japan.MethodsCross-sectional surveys were given to 1,350 residents over the age of 18 who were selected from resident registration lists in Tochigi prefecture. Residents were questioned whether they would agree to have a CFR system in their community and whether they would participate as a responder. Positive attitudes about the cross-sectional study led us to conduct pilot CFR trials. Trials were conducted in rural areas of Tochigi prefecture by local EMS personnel. We were able to discuss and develop CFR introduction guidelines for Japanese communities using the results of the individual surveys, pilot trials, and other countries’ guidelines. Finally, our CFR system, which referred to developed CFR introduction guidelines, was introduced into Ishikawa prefecture’s Shioya town (population of 710).ResultsA total of 92.5% of Tochigi residents either strongly agreed or agreed to have a CFR system in their community, and 16.7% of Tochigi’s residents chose to participate. The two CFR introduction prerequisites were identified as: (1) an information delivery system for CFR and (2) budget preparation. CFR introduction guidelines were developed, and a CFR system was introduced in Shioya town on 4 November 2012 with 32 participants. On 1 January 2013, a CFR responded for the first time, and the CFR system worked efficiently.ConclusionsBy providing information about the CFR system to the community and preparing several infrastructural elements, it was possible to introduce and operate a successful CFR system in Japan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
