Abstract P168: High Incidence of Delay in Emergency Call and Analysis of the Causes in Japan: Need of public relations that emphasize “Call 119 when someone becomes unresponsive”
Incidence and causes of delay in Emergency call were analyzed in 3267 out-of-hospital cardiac arrests that were witnessed by bystanders or not witnessed but found by citizens from April 1, 2003 to March 31, 2007 in Ishikawa Prefecture. Emergency calls were considered to be significantly delayed when interval of collapse or event recognition to call exceeded 2 min. The incidence of delay was 32.9% (1076/3267) in the all arrests and significantly higher in urban (Non-Central) areas than in rural (the Central) area (691/1539 vs. 385/1728, p<0.001). Telephone-assisted CPR was performed in 501 out of 1076 delayed cases and CPR was initiated in 331 cases. The proportions of ROSC and successful resuscitation were significantly lower when the call was delayed (178/1076 vs. 490/2191 p<0.001, 153/1076 vs. 415/2191 p<0.001, respectively). As shown in Table, the major causes of delay were identified in 906 out of 1076 cases. The delay was considered to be correctable in 607 cases if the bystanders or citizens had understood when they should call 119. These results indicate that significance of early call should be more emphasized in basic life support courses. The public relations that emphasize “Call 119 when someone becomes unresponsive” may be necessary for all citizens to be aware of the significance of early call.
