Health care costs related to out-of-hospital cardiopulmonary arrest in Japan

ObjectivesAlthough cost analyses for emergency care are essential, data on costs of care for out-of-hospital cardiopulmonary arrest (OHCA) are scarce. The present study aimed to analyze health care costs related to OHCA using a nationwide administrative database in Japan.MethodsUsing the Diagnosis Procedure Combination database in Japan, we identified OHCA patients who were transported to 779 emergency medical centres between July and December in 2008 and 2009. We assessed patient survival and discharge status, receipt of specific treatments, and costs of in-hospital care.ResultsA total of 21,750 OHCA patients were identified. Overall, 59.6% were males, and the average age was 70.3 years. Of them, 1394 (6.4%) resulted in death without attempted resuscitation after hospital arrival (Group A), 14,973 (69.0%) died on admission day despite resuscitation attempts (Group B), 3680 (17.0%) died at ≥2 days after admission despite resuscitation attempts (Group C), 785 (3.6%) survived and were discharged to home (Group D) and 873 (4.0%) survived and discharged to other than home (Group E). The median total costs were $434, $1735, $4869, $28,097 and $31,161 in Groups A to E, respectively. Positive survival status, longer hospital stay and receipt of specific treatments were significant predictors of higher total costs. After adjustment for these factors, higher age was associated with lower costs.ConclusionsThe findings in the present study add further evidence to existing knowledge about healthcare costs related to OHCA.
