Cost-effectiveness of a novel smartphone application to mobilize first responders after witnessed OHCA in Belgium

Table 2 Estimation of survival to discharge and neurological outcome after witnessed OHCA of cardiac origin, depending on the type of first response

%	EMS			bCPR			bCPR + AED
%	Worst	Medium	Best	Worst	Medium	Best	Worst	Medium	Best
Survival to discharge	7.8	9.4^*	11.0	10.5	14.9*	19.3	18.2	23.2	72.0
Deceased	92.2	90.6	89.0	89.5	85.1	80.7	81.8	76.9	28.0
CPC 1–2	6.6	8.0	9.4	9.0	12.7	16.4	15.5	19.7	61.2
CPC 3–4	1.2	1.4	1.7	1.6	2.2	2.9	2.7	3.5	10.8

Data was retrieved from literature. With EMS: first response by the emergency medical system, bCPR: early bystander/first responder CPR before arrival of the EMS, bCPR + AED: early bystander/first responder CPR and defibrillation before arrival of the EMS, CPC: cerebral performance category as indication of neurological outcome (1–2: good, 3–4: bad)
*The medium case was calculated as the average value of both extreme values
