ABSTRACT
Objetivo: identificar os fatores associados ao tempo da morte de vítimas de trauma. Método: coorte retrospectiva que analisou laudos de autópsia de vítimas de trauma admitidas em 2015 no Instituto Médico Legal Central de São Paulo, Brasil. O tempo da morte foi identificado a partir do momento da ocorrência do trauma até a confirmação do óbito. O modelo linear generalizado foi aplicado para análise dos dados. Resultados: entre as 1.500 vítimas fatais (75,7% homens; idade média 49,7 anos), prevaleceram as quedas (33,5%), seguidas das agressões (27,8%). Os fatores associados ao tempo da morte foram número de regiões corporais afetadas (p<0,001), tipo de trauma (p<0,001), sexo (p=0,009), gravidade do trauma segundo New Injury Severity Score (p<0,001), agressões (p<0,001) e lesões autoprovocadas intencionalmente (p<0,001). Conclusão: mulheres, vítimas de traumas que envolveram intencionalidade de provocar a morte e com elevada gravidade apresentaram tempo de sobrevida reduzido após a(s) lesão(ões).
Objective: to identify factors associated to the time of death of trauma victims. Method: a retrospective cohort that analyzed autopsy reports of trauma victims admitted in 2015 at the Central Institute of Forensic Medicine of São Paulo, Brazil. The time of death was identified from the trauma moment to the confirmation of death. The generalized linear model was applied to analyze the data. Results: among the 1,500 fatal victims (75.7% were men; mean age of 49.7 years old), falls prevailed (33.5%), followed by aggressions (27.8%). The factors associated with the time of death were the number of body areas affected (p<0.001), type of trauma (p<0.001), gender (p=0.009), trauma severity according to the New Injury Severity Score (p<0.001), assaults (p>0.001), and intentionally self-harm injuries (p<0.001). Conclusion: women, victims of traumas with the intention of causing death and with high severity presented a reduced survival time after the injury(ies).

Fall represents an important cause of death and its relation with the population aging evidences the need of a broad analysis considering different aspects associated with its occurrence. The objective of this study was to compare fatal victims due to unintentional fall among adults, young olds, olds, and oldest olds, according to sociodemographic data, characteristics, and severity of the trauma. This study is a cross-sectional, comparative study analyzing autopsy reports of fatal victims due to fall, admitted to the Medical Legal Institute of Sao Paulo, Sao Paulo, Brazil, in 2015. The following age groups were: adults (≥18 and <60 years), young olds (≥60 and <70 years), olds (≥70 and <80 years), and oldest olds (≥80 years). The Pearson's χ, Fisher's exact, Kruskal-Wallis, and Dunn tests were applied to compare the groups, with a significance level of 5%. Regarding the 469 fatalities analyzed (57.8% males, mean age: 71.3 ± 18.2 years), there was a higher frequency of oldest olds (43.5%), ground-level falls (70.1%), femoral fractures (35.0%), and delayed deaths (79.6%) due to posttraumatic complications (57.2%). Adults, young olds, olds, and oldest olds differed significantly (p ≤ .005) in relation to the total of analyzed variables, with a special remark on the differences between the age extremes. High frequencies of femoral fractures and delayed deaths due to complications of treatment in low-severity fall victims, especially those older than 70 years, make it necessary to improve fall prevention programs in the older adults and to create a line of care for this population.
