“…The most common symptom of unrecognized cardiac arrest was unconsciousness, which was the same as the study of Crabb et al [12]. Unconsciousness was also the most reported symptom of cardiac arrest in our study as in the study of Watkins et al and a recent American Heart Association adult basic and advanced life support guideline [1], [3].…”

“…In the study of Watkins et al determining breathing pattern can lead to an increase of 7 points of recognized cardiac arrest if the call handler was strict on the protocol [3]. The main obstacle of recognizing OHCA was the difficulty of determining the patient's respiratory status for bystanders [12]. Another important reported symptom of cardiac arrest in our study was seizure-like activity, which may mislead the call handler from recognizing cardiac arrest to epilepsy as in the study of Vaillancourt et al [5], [13].…”

BACKGROUND: To improve survival rate, the main focus of adult cardiac arrest management includes rapid recognition, prompt administration of cardiopulmonary resuscitation (CPR), defibrillation for shockable rhythms, post-return of spontaneous circulation (ROSC) care, and identification and treatment of underlying causes. This study aimed to identify the determinants of unrecognized cardiac arrest, and to study the recognition rate of out-of-hospital cardiac arrest (OHCA) by emergency medical services call handlers. METHODS: We included OHCA patients who were transferred to hospital via Emergency Medical Services (EMS) of Srinagarind hospital, Khon Kaen, Thailand, from 1st January 2020 to 31st December 2020. The primary outcome was to identify symptoms that lead to an unrecognized cardiac arrest by the EMS call handlers. Secondary outcomes were to identify the recognition rate of OHCA by emergency medical services call handlers, and assess the outcome of CPR performed on OHCA patients. RESULTS: There were a total of 58 patients in the present study, 26 patients (44.8%) and 32 patients (55.2%) belonged to the unrecognized and recognized cardiac arrest groups, respectively. The most common symptoms that led to unrecognized cardiac arrest were a state of unconsciousness (46.2%), major trauma (15.4%), and seizure-like activity (11.5%). The rate of ROSC was higher in the unrecognized cardiac arrest group (34.6% vs. 15.6%) but the rate of survival to hospital discharge was higher in the recognized cardiac arrest group (6.3% vs 0%). CONCLUSIONS: Falling unconscious is the most common symptom of unrecognized OHCA cases seen by EMS in Thailand. Basic life support, especially an immediate assessment of a patient’s respiratory status should be taught in health programs in school or through public service channels.
