To evaluate and compare survival after out-of-hospital (OHCA), where an automated external defibrillator (AED) was used, in densely, moderately and thinly populated areas. Also, to evaluate the association between AED retrieval distance and survival after OHCA. ⋯ Survival after OHCA, where an AED was used, did not seem to differ in thinly, moderately and densely populated areas. The length of the AED retrieval distance, however, was correlated with reduced survival after adjusting for other potentially explanatory variables.

Rearrest occurs commonly after initial resuscitation following out-of-hospital cardiac arrest (OHCA). We determined (1) the predictors of rearrest during hospitalisation that can be identified in the hours immediately after OHCA, (2) the association between rearrest and favourable long-term outcomes, and (3) the predictors of favourable long-term outcomes in rearrest patients. ⋯ Rearrest during hospitalisation after OHCA was inversely associated with 6-month favourable outcomes. We identified several risk factors for rearrest and prognostic factors for patients resuscitated from first rearrest.

Mathematical optimization of automated external defibrillator (AED) placement has demonstrated potential to improve survival of out-of-hospital cardiac arrest (OHCA). Existing models mostly aim to improve accessibility based on coverage radius and do not account for detailed impact of delayed defibrillation on survival. We aimed to predict OHCA survival based on time to defibrillation and developed an AED placement model to directly maximize the expected survival rate. ⋯ We developed a novel AED placement model based on the impact of time to defibrillation on OHCA outcomes. Mathematical optimization can improve OHCA survival.

Veno-arterial Extracorporeal Life Support (V-A ECLS) has gained increasing place into the management of patients with refractory cardiogenic shock or cardiac arrest. Both surgical and percutaneous approach can be used for cannulation, but percutaneous approach has been associated with fewer complications. Angio-guided percutaneous cannulation and decannulation may further decrease the rate of complication. We aimed to compare outcome and complication rates in patients supported with V-A ECLS through percutaneous angio-guided versus surgical approach. ⋯ Compared to surgical approach, angio-guided percutaneous V-A ECLS implantation is associated with fewer major vascular complications. Larger studies are needed to confirm those results and address their impact on mortality.
