Cost of out-of-hospital cardiac arrest survivors compared with matched control groups

Societal costs of out-of-hospital cardiac arrest (OHCA) survivors may be extensive due to high health care utilization and sick leave. Knowledge of the costs of OHCA survivors may guide decision-makers to prioritize health resources.

The aims of the study were to evaluate the costs of OHCA survivors from a societal perspective, and to compare these costs to the costs of individuals with non-cardiac arrest myocardial infarction (MI) and individuals with no cardiac disease (non-CD).

From the Danish OHCA Registers, survivors, with a cardiac arrest between 2005-2018 were identified. Each case was assigned one MI control and one non-CD control, matched on gender and age. Based on register data, costs of healthcare utilization, sick leave, vocational rehabilitation, disability pension and other social benefits one year before event and five years after, were estimated.

In total 5,646 OHCA survivors were identified with associated control groups. The mean costs for OHCA survivors during the 6-year period were €119,106 (95%CI: 116,297-121,916), with €83,472 (95%CI: 81,392-85,552) being healthcare costs. Mean costs of OHCA survivors were €49,132 higher than the MI-control group and €100,583 higher than the non-CD control group.

Total costs of OHCA survivors were considerably higher than costs of MI- and non-CD controls. Hospital costs were highest during the first year after event, and work inability during the second to fifth year with sick leave and later disability pension as main burdens.
