Abstract

Purpose: Automated External Defibrillator (AED) usage in out-of-hospital cardiac arrests (OHCAs) improves the survival of patients. In Singapore, public AEDs are protected by locked boxes with a 'break glass' mechanism to deter theft. Community responders have sustained injuries while breaking glass to retrieve AEDs. This unprecedented study aimed to elucidate the factors influencing successful retrieval of an AED and to document the prevalence of injuries. Methods: A survey was created and distributed. Participants were required to have responded to an OHCA in the past 12 months. Comparison tests were performed with the Fischer-Freeman-Halton Exact test or Pearson chi square test at 5% significance levels, and with multiple logistic regression with a logit link function. Results: Eighty-eight participants were eligible. The success of retrieving an AED was found not to be impacted by occupation, age, gender or time. Participants who responded to an OHCA because of activation by the myResponder App were more likely to retrieve an AED successfully. (AOR 11.111, 95% CI: 2.141-58.824) Conclusion: Use of the myResponder mobile application is associated with the greater success of retrieving an AED. Successful retrieval of an AED is not impacted by time, gender, age, or the occupation of the responder. Community responders in Singapore remain motivated to respond to Cardiac Arrests despite risk of injury.

연구 목적: 병원 밖 심정지(OHCA)에서 자동제세동기(AED)의 사용은 환자의 생존율을 향상시킨다. 싱가포르는 절도를 막고자 공공 AED를 '브레이크 글래스' 기전의 잠금 박스로 보호하고 있는데 지역사회 대응자들은 AED를 회수하기 위해 유리를 깨면서 부상을 당하곤 했다. 최초로 시도한 본 연구는 성공적인 AED 회수에 영향을 미치는 요인들을 밝히고 만연한 부상을 문서화하고자 하였다. 연구 방법: 설문지를 작성, 배포하였다. 참가자는 지난 12개월 동안 OHCA에 대처한 자들이다. 비교 검정은 피셔-프리만-할턴 정확 검정 또는 피어슨 카이제곱 검정을 사용하여 5% 유의 수준에서 시행되었고, 로짓링크함수를 사용하여 다중로지스틱회귀분석을 시행하였다. 연구 결과: 88명의 참가자가 적격했다. 성공적인 AED의 회수는 직업, 연령, 성별 및 시간 영향을 받지 않았다. myResponder 앱의 활성화로 OHCA에 대응했던 참가자들은 성공적으로 AED를 회수할 가능성이 높았다. (AOR 11.111, 95% CI: 2.141-58.824) 결 론: 모바일 myResponder 앱을 활용할 경우 AED회수 성공률이 훨씬 높았다. AED의 성공적 회수는 시간 뿐만 아니라 이용자의 성별, 연령, 직업과 무관했다. 싱가포르에서 지역사회 대응자들은 부상 위험에도 불구하고 심정지에 대응할 적극적 자세가 되어 있다.
