RESUMO
Introduction: The aim of this study was to consider the definition of solitary death by examining characteristics of cases, and to explore the impact of the coronavirus pandemic.Methods: Subjects were individuals with post-mortem examination and autopsy imaging data recorded between 2017 and 2022. Subjects were classified by whether they passed away at home (solitary). We investigated differences between groups in their causes of death, time elapsed between death and discovery, presence or absence of housemates, and prior symptoms.Results: There were 129 cases (79.9%) of solitary death and 41 cases (24.1%) of death outside the home. Solitary death cases were significantly younger. Among these, less than half were discovered more than a day after death, lived alone, or were older adults. Older adults and those discovered more than a day after death were more likely to have trauma as their official cause of death. The frequency and characteristics of solitary death did not change before or after the coronavirus pandemic.Conclusion: Preventive measures for solitary death should not be limited to older adults or those living alone. In particular, deaths from diseases other than sudden death, trauma in older adults, and cases where symptoms were present or medical attention was sought before death are potentially preventable. Countermeasures for solitary death are important in the post-coronavirus pandemic period.
