| Outline of Final Research Achievements |
Although an autopsy is necessary for determining cause of death, Japan has the lowest autopsy rate among advanced nations. We examined whether postmortem imaging is useful for investigating cause of death in cardiopulmonary arrest on arrival (CPAOA) at emergency hospitals. We found that postmortem CT was useful for detecting post-traumatic changes and hemorrhagic lesions, but not ischemic lesions or infections. In some cases, postmortem CT was performed to assess therapeutic efficacy. A death certificate or postmortem certificate was issued for many patients without further examination such as clinical laboratory tests, and cause of death was not accurately determined. Postmortem images are considered vital to implementation of the Medical Accidents Investigation System. The establishment of widespread postmortem imaging and corroborating complementary examinations, not to mention an increased autopsy rate, are urgently needed to achieve accurate cause of death investigations.
