Comparison between Injury Severity Score (ISS) and New Injury Severity Score (NISS) in predicting mortality of thoracic trauma in a tertiary hospital / Comparação entre o Injury Severity Score (ISS) e o New Injury Severity Score (NISS) na predição da mortalidade de traumas torácicos atendidos em um hospital terciário

ABSTRACT Introduction: measuring the severity of traumatic injuries is crucial for predicting clinical outcomes. Whereas the Injury Severity Score (ISS) has limitations in assigning scores to injuries at the same site, the New Injury Severity Score (NISS) corrects for this problem by taking into account the three most severe injuries regardless of the region of the body. This study seeks to comprehend the clinical and epidemiological profile of trauma patients while comparing the effectiveness of scales for predicting mortality. Methods: a descriptive, observational and retrospective study using records of patients who underwent thoracotomy at the Hospital das Clínicas of the Federal University of Triângulo Mineiro between 2000 and 2019. Demographic data, mechanisms of injury, affected organs, length of stay and mortality were analyzed. Injury severity was assessed using the ISS and NISS, and statistical analyses were conducted using MedCalc and SigmaPlot. Results: 101 patients were assessed, on average 29.6 years old, 86.13% of whom were men. The average duration of hospitalization was 10.9 days and the mortality rate was 28.7%. The ROC curve analysis revealed a sensitivity of 68.97%, specificity of 80.56% and area under the curve of 0.837 for the ISS, and 58.62%, 94.44% and 0.855 for the NISS, respectively. The Youden index was 0.49 for the ISS and 0.53 for the NISS. Conclusion: the study demonstrated comparable efficacy of NISS and ISS in predicting mortality. These findings hold significance in the hospital setting. Professionals must be familiar with these scales to utilize them competently for each patient.

RESUMO Introdução: a medição da gravidade das lesões traumáticas é essencial para prever os desfechos clínicos. Enquanto o Injury Severity Score (ISS) tem limitações ao atribuir pontuações às lesões no mesmo local, o New Injury Severity Score (NISS) corrige esse problema ao considerar as três lesões mais graves independentemente da região corporal. Este estudo visa entender o perfil clínico-epidemiológico dos pacientes traumatizados, comparando a eficácia das escalas para prever mortalidade. Métodos: estudo descritivo, observacional e retrospectivo utilizando registros de pacientes submetidos à toracotomia no Hospital das Clínicas da Universidade Federal do Triângulo Mineiro entre 2000 e 2019. Dados demográficos, mecanismos de lesão, órgãos afetados, tempo de internação e mortalidade foram analisados. A gravidade das lesões foi avaliada usando o ISS e NISS, e as análises estatísticas foram conduzidas no MedCalc e SigmaPlot. Resultados: Foram avaliados 101 pacientes, em média com 29,6 anos, sendo 86,13% homens. A média da internação foi de 10,9 dias e a taxa de mortalidade foi de 28,7%. A análise da curva ROC revelou uma sensibilidade de 68,97%, especificidade de 80,56% e área sob a curva de 0,837 para o ISS, e 58,62%, 94,44% e 0,855 para o NISS, respectivamente. O índice de Youden indicou 0,49 para o ISS e 0,53 para o NISS. Conclusão: o estudo demonstrou semelhante eficácia entre o NISS e o ISS na previsão de mortalidade. Esses resultados geram implicações importantes na aplicação dessas escalas no ambiente hospitalar. É essencial que os profissionais conheçam tais escalas para aplica-las adequadamente no contexto de cada paciente.

Trauma Registry: Trauma Quality indicators analysis in hospitalized patients / Registro de Trauma: análise dos Filtros de Qualidade nos pacientes internados

ABSTRACT Purpose: to consolidate a Trauma Register (TR) trough REDCap data acquisition platform and to validate, in this context, local Quality Indicators (QI) as improvement opportunities in trauma management. Methods: continuous data acquisition of all patients admitted in Irmandade da Santa Casa de Misericórdia de São Paulo adult Trauma bay and it's validation in REDCap platform; 6 months retrospective cohort of QI impact in length of hospitalar stay, complications and mortality. Fisher, Chi-squared, Wilcoxon and Kruskal-Wallis tests were used to correlate QIs fails with the endpoints, considering p<0.05 and CI <95% as statically significant. Results: 465 were admitted in Trauma bay, with 137 patients hospitalized (29.5%); the number of QIs compromised were related with more complications (p=0.075) and increased length of stay (p=0.028), especially the delay in open fracture's surgical management, which increased the severe complications' incidence (p=0.005). Conclusion: the REDCap data acquisition platform is useful as a tool for multi center TR implementation, from ethical and logistical point of view; nevertheless, the proposed QIs are validated as attention points in trauma management, allowing improvements in traumatized patients treatment.

RESUMO Objetivo: implementação de Registro de Trauma (RT) através da plataforma REDCap e validação dos Filtros de Qualidade (FQ) desenvolvidos como pontos de melhora no atendimento ao traumatizado.

A correlação do comprometimento dos FQ com os desfechos foi obtida através dos testes de Fisher, Qui-Quadrado, Wilcoxon e Kruskal-Wallis, considerando p<0,05 e IC 95% como significativos. Resultados: incluídos no estudo 465 pacientes admitidos no período de estudo, com necessidade de internação em 137 casos (29,5%); o número de FQs comprometidos relacionou-se com maior número de complicações (p=0,075) e maior tempo de internação (p=0,028), sobretudo o atraso na ida ao Centro Cirúrgico de fraturas expostas, que aumentou a incidência de complicações graves (p=0,005). Conclusão: a plataforma REDCap é adequada e útil na implementação de RT, permitindo o uso ético e multicêntrico de dados; os FQs propostos determinam pontos de atenção a serem revistos no atendimento do trauma, permitindo melhorias na qualidade de atendimento ao paciente traumatizado.

Is post-traumatic stress disorder related to the severity of physical trauma?

SUMMARY OBJECTIVE: Trauma can cause physical morbidity and even result in death. Besides, it can lead to serious mental problems as well. The most well-known mental health problem is post-traumatic stress disorder. Through this study, it was primarily aimed to find out whether the severity of physical trauma is effective on post-traumatic stress disorder and other risk factors if any. METHODS: The reports of the patients who were transferred to the Turkish Council of Forensic Medicine Third Speciality Board between January 01, 2019, and December 31, 2020, for post-traumatic invalidity or disability evaluation and whose psychiatric examinations were performed were retrospectively analyzed in the electronic environment. RESULTS: It was found that 34 (26.4%) of the patients had a diagnosis of post-traumatic stress disorder (under treatment for at least 6 months), while 76 (58.9%) of them did not have a psychiatric disease and 19 (14.7%) of them had mental disorders not associated with trauma (i.e., affective disorder, anxiety disorder, etc.). No significant correlation was found between trauma scores and post-traumatic stress disorder (p>0.05). CONCLUSION: Based on the results of our study, post-traumatic stress disorder and the severity of physical trauma are not significantly correlated. Being of female gender, sustaining a non-accidental injury, and witnessing a fatal event stand out as significant risk factors.

Coagulopathy, metabolic acidosis and SIRS were associated with mortality. A proportion of 72.50% and 3.33% STR < 6 was observed in polytrauma patients who died and survived (p = 0.001); sensitivity: 73% CI 95% (59% - 86%), specificity: 97% CI 95% (92% - 100%), positive predictive value: 94% CI 95% (85% - 100%) and negative predictive value: 84% CI 95% (75% - 93%). The area under the curve was 96.50% in predicting mortality by RTS in polytrauma patients. Conclusion: The revised trauma score is a good predictor of mortality in polytrauma patients.

Trauma severity predictors / Preditores de gravidade no trauma

This review aimed to determine which are the indexes for early detection and evaluation of clinical and physiological deterioration of traumatized patients. A Scoping Review according to the methods proposed by Joanna Briggs Institute (JBI) was performed from February 2018 to December 2018 on LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed), and SCOPUS databases. Sixty-two studies were included, of which 43 evaluated patients with general trauma. A variety of physiological variables, such as Glasgow Coma Score, Glucose, Days in the Intensive Care Unit, Lactate, and predictor indexes - Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Revisited Trauma Score (RTS), and APACHE II were identified. The values observed in the studies among patients were compared to the ones determined by the basic literature, being called Critical Values (CV). The group of gravity indexes, besides clinical and regulatory protocols, found in this review are the solidification of the healthcare process involving the traumatized patient's responses to the actions of the healthcare team. The analysis of these indexes must be emphasized to determine, with greater reliability, the prognosis of the patient. With these data, it may be possible to effectively predict mortality rates (AU).

O objetivo desta revisão é determinar os índices para detecção precoce e avaliação clínica e fisiológica para deterioração de pacientes do trauma. Conduziu-se uma revisão de escopo de acordo com os métodos propostos pelo Joanna Briggs Institute (JBI) entre fevereiro de 2018 a dezembro de 2018 nas bases de dados LILACS (Literatura Latina-Americana e do Caribe em Ciências da Saúde), National Library of Medicine (PubMed) e SCOPUS. Foram incluídos 62 estudos, dos quais 43 sobre trauma geral. Encontrou-se grande diversidade de variáveis fisiológicas, como Escala de Coma de Glasgow, Glicose, dias em Unidade de Terapia Intensiva, lactato e índices preditores­Injury Severity Score (ISS), Trauma Injury Severity Score (TRISS), Reviseted Trauma Score (RTS) e APACHE II. Os valores observados nos pacientes dos estudos encontrados foram comparados com os da literatura básica, sendo denominados Valores Críticos (CV). O grupo de índices de gravidade encontrados neste estudo, além de protocolos reguladores e clínicos, são a solidificação do processo de cuidado envolvendo a resposta das ações da equipe em saúde ao paciente de trauma. A análise desses índices deve ser enfatizada para determinar com maior confiabilidade o prognóstico do paciente. Com esses dados, pode ser possível predizer a taxa de mortalidade com maior acurácia (AU).

De un centro de trauma a un sistema de trauma en el suroccidente colombiano / From a Trauma Center to a Trauma System in Southwest Colombia

Introducción. El objetivo de este estudio fue evaluar el impacto sobre la mortalidad según el perfil de ingreso a un centro de trauma del suroccidente colombiano, como método para entender las dinámicas de atención del paciente con trauma. Métodos. Se realizó un subanálisis del registro de la Sociedad Panamericana de Trauma asociado a un centro de trauma en el suroccidente colombiano. Se analizaron los pacientes atendidos entre los años 2012 y 2021. Se compararon los pacientes con condición de ingreso directo y aquellos que ingresaron remitidos. Se hicieron análisis de poblaciones de interés como pacientes con trauma severo (ISS > 15) y pacientes con/sin trauma craneoencefálico. Se evaluó el impacto de los pacientes remitidos y su condición al ingreso sobre la mortalidad. Resultados. Se incluyeron 10.814 pacientes. La proporción de pacientes remitidos fue del 54,7 %. Los pacientes que ingresaron remitidos presentaron diferencias respecto a la severidad del trauma y compromiso fisiológico al ingreso comparado con los pacientes con ingreso directo. Los pacientes remitidos tienen mayor riesgo de mortalidad (RR: 2,81; IC95% 2,44-3,22); sin embargo, es el estado fisiológico al ingreso lo que impacta en la mortalidad. Conclusión. Los pacientes remitidos de otras instituciones tienen un mayor riesgo de mortalidad, siendo una inequidad en salud que invita a la articulación de actores institucionales en la atención de trauma. Un centro de trauma debe relacionarse con las instituciones asociadas para crear un sistema de trauma que optimice la atención de los pacientes y la oportunidad

Introduction. This study aims to evaluate the impact on mortality by admission profile to a trauma center in Southwest Colombia between direct and referred patients, as a method to understand the dynamics of trauma care.Methods. A sub-analysis of the Panamerican Trauma Society registry associated with a trauma center in Southwest Colombia was performed. Patients attended between 2012-2021 were analyzed. Patients with direct admission and referred condition were compared. Analyses of populations of interest such as patients with severe trauma (ISS > 15) and patients with/without brain trauma were made. The impact of referred patients and their admission status on mortality was evaluated. Results. A total of 10,814 patients were included. The proportion of referred patients was 54.7%. Patients admitted referred vs. with direct admission have differences regarding trauma severity and physiological compromise on admission. The referred patient has a higher risk of mortality (RR: 2.81; 95% CI 2.44-3.22). There is a high proportion of penetrating trauma by gunshot wounds. However, it is the physiological state at admission that impacts mortality. Conclusion. Patients referred from other institutions have a higher mortality risk, being a health inequity that invites the articulation of institutional actors in trauma care. A trauma center should relate to partner institutions to create a trauma system that optimizes care and timeliness

Conclusão: os dados obtidos em nosso estudo estão em conformidade com a literatura mundial, reforçando a necessidade de um esforço contínuo para realização da TR respeitando suas indicações e limitações em pacientes vítimas de trauma grave penetrante ou contuso.

The role of autopsy on the diagnosis of missed injuries and on the trauma quality program goal definitions: study of 192 cases / Valor da autópsia no diagnóstico de lesões despercebidas e na definição de metas para programa de qualidade em trauma: estudo de 192 casos

ABSTRACT Objective: to assess the role of autopsy in the diagnosis of missed injuries (MI) and definition of trauma quality program goals. Method: Retrospective analysis of autopsy reports and patient's charts. Injuries present in the autopsy, but not in the chart, were defined as "missed". MI were characterized using Goldman's criteria: Class I, if the diagnosis would have modified the management and outcome; Class II, if it would have modified the management, but not the outcome; Class III, if it would not have modified neither the management nor the outcome. We used Mann-Whitney's U and Pearson's chi square for statistical analysis, considering p<0.05 as significant. Results: We included 192 patients, with mean age of 56.8 years. Blunt trauma accounted for 181 cases, and 28.6% were due to falls from the same level. MI were diagnosed in 39 patients (20.3%). Using Goldman's criteria, MI were categorized as Class I in 3 (1.6%) and Class II in 11 (5.6%). MI were more often diagnosed in the thoracic segment (25 patients, 64.1% of the MI). The variables significantly associated (p<0.05) to MI were: time of hospitalization < 48 h, severe trauma mechanism, and not undergoing surgery or computed tomography. At autopsy, the values of ISS and NISS were higher in patients with MI. Conclusion: the review of the autopsy report allowed diagnosis of MIs, which did not influence outcome in their majority. Many opportunities of improvement in quality of care were identified.

RESUMO Objetivo: Avaliar a utilidade da autópsia no diagnóstico de lesões despercebidas (LD) e no estabelecimento de metas para programa de qualidade em trauma. Método: análise retrospectiva dos laudos de autópsia por trauma entre outubro/2017 e março/2019 provenientes do mesmo hospital. Lesões descritas na autópsia, mas não no prontuário médico, foram consideradas como despercebidas (LD) e classificadas pelos critérios de Goldman: Classe I: mudariam a conduta e alterariam o desfecho; Classe II: mudariam a conduta, mas não o desfecho; Classe III: não mudariam nem a conduta nem o desfecho. As variáveis coletadas foram comparadas entre o grupo com LD e os demais, através de método estatístico orientado por profissional na área. Consideramos p<0,05 como significativo. Resultados: analisamos 192 casos, com média etária de 56,8 anos. O trauma fechado foi o mecanismo em 181 casos, sendo 28,6% por quedas da própria altura. LD foram observadas em 39 casos (20,3%), sendo 3 (1,6%) classe I e 11 (5,6%) classe II. O tórax foi o segmento com maior número de LD (25 casos - 64,1% das LD). Foram associados à presença de LD (p<0,05): tempo de internação menor que 48 horas, mecanismo de trauma grave e a não realização de procedimento cirúrgico ou tomografia. Nos óbitos até 48h, valores de ISS e NISS nas autópsias foram maiores que os da internação. Conclusão: a revisão das autópsias permitiu identificação de LD, na sua maioria sem influência sobre conduta e prognóstico. Mesmo assim, várias oportunidades foram criadas para o programa de qualidade.

Ocular trauma score as a visual prognostic factor of open globe injuries in a hospital of southern Brazil / Escore de Trauma Ocular como fator de prognóstico visual em traumas oculares abertos em um hospital do sul do Brasil

ABSTRACT Purpose: To compare the visual acuities predicted by the Ocular Trauma Score and each one of the Ocular Trauma Score variables with the final visual acuities of the victims of open globe injuries in a southern Brazil hospital. Methods: A total of 120 eyes of 119 individuals with open globe injuries were analyzed in this cross-sectional retrospective study that was developed in a university hospital. The information on age, sex, affected eye, trauma mechanism, and other data (such as initial visual acuity, the presence of globe rupture, perforating injury, endophthalmitis, retinal detachment, and afferent pupillary defect) were used to calculate the Ocular Trauma score, and the final visual acuities of all patients were retrieved from the patients' medical records. Results: We noted an agreement between the visual acuity predicted by the Ocular Trauma Score and the final visual acuity in our study. An isolated analysis of the variables demonstrated significance with regard to the initial visual acuity (p<0.001), retinal detachment (p=0.001), and afferent pupillary defect (p=0.004). No significant differences were detected between the final visual acuities and those determined by the Ocular Trauma Score system for the present study population. Conclusions: The Ocular Trauma Score can be applied for the determination of the visual prognoses of victims of open globe injuries. The most significant variables in this predictive analysis are initial visual acuity, retinal detachment, and afferent pupillary defect. Prospective studies with larger sample sizes are required to confirm our findings.

RESUMO Objetivo: Comparar a acuidade visual prevista pelo Escore de Trauma Ocular com a acuidade visual final dos pacientes vítimas de trauma ocular aberto atendidos em hospital no sul do Brasil. Métodos: Foram analisados 120 olhos de 119 vítimas de trauma ocular aberto. Foi realizado um estudo observacional e retrospectivo em hospital universitário. Foram extraídos dados de prontuários relacionados a idade, sexo, olho acometido e mecanismo de trauma, bem como dados para o cálculo do Escore de Trauma Ocular (acuidade visual inicial, presença de ruptura de globo, perfuração, endoftalmite, descolamento de retina, defeito pupilar aferente) e acuidade visual final. Resultado: Houve concordância entre a acuidade visual prevista pelo Escore de Trauma Ocular e a acuidade visual final prevista no presente estudo. A análise isolada das variáveis demonstrou significância para acuidade visual inicial (p<0,001), para descolamento de retina (p=0,001) e para defeito pupilar aferente (p<0,004). Não houve diferença significativa entre a acuidade visual final do estudo original do Escore de Trauma Ocular. e na população abordada no presente estudo. Conclusão: O Escore de Trauma Ocular pode ser aplicado à população estudada no presente estudo como ferramenta de determinação do prognóstico visual em vítimas de trauma ocular aberto. As variáveis mais significativas são acuidade visual inicial, descolamento de retina e defeito pupilar aferente.

Mortalidad en hospitalizados con traumatismo torácico: variables asociadas, causas y distribución temporal / Associated variables, causes and time distribution of mortality in thoracic trauma patients

Resumen Introducción: Los traumatismos están entre las diez principales causas de muerte a nivel mundial y son la primera en jóvenes. El traumatismo torácico (TT) está presente en un alto porcentaje de las muertes por traumatismos y es la segunda causa de muerte después del traumatismo encefalocraneano. Objetivos: Analizar las variables asociadas a mortalidad, las causas principales y la distribución temporal de la mortalidad en hospitalizados fallecidos con TT. Materiales y Método: Estudio observacional de hospitalizados con TT, período enero de 1981 a diciembre de 2018. Revisión de protocolos prospectivos de TT y base de datos. Se consignaron las causas de muerte sindromáticas principales y se realizó una regresión logística para variables asociadas a mortalidad. Se utilizó SPSS25® con pruebas chi-cuadrado para comparar clasificación, tipo de TT y su distribución temporal, considerando significativo p < 0,05. Resultados: Total 4.297 TT, mortalidad global de 120 (2,8%) casos. Las principales variables independientes asociadas a mortalidad fueron el deterioro fisiológico al ingreso, el hemotórax masivo y el TT por arma de fuego. La principal causa de muerte fue el shock hipovolémico, con diferencias significativas según tipo de TT en las primeras 4 y 24 horas. En la distribución temporal se observó que las muertes con TT penetrante y aislado fueron más precoces y no se evidenció un nuevo peak en la mortalidad luego de la primera semana. Conclusiones: Se observaron variables independientes asociadas a mortalidad en hospitalizados con TT, siendo el deterioro fisiológico al ingreso el factor más importante. Además, existen diferencias significativas en las causas de muerte y distribución temporal de la mortalidad entre diferentes subgrupos de hospitalizados con TT.

Background: Trauma is one of the ten leading causes of death worldwide and the first among the youth. Thoracic trauma (TT) is present in a high percentage of deaths due to trauma and is the second leading cause of death after traumatic brain injury. Aim: To analyze the mortality associated variables, major causes and temporal distribution of mortality among dead hospitalized patients with TT. Materials and Method: Observational study in hospitalized patients with TT, period January 1981 to December 2018. Review of prospective TT protocols and data base. Major syndromic causes of death were recorded and a logistic regression for variables associated with mortality was made. SPSS25® with chi-quadrat tests was used to compare classification, type of TT and temporal distribution. A p value < 0,05 was considered significant. Results: Total 4.297 TT and global mortality was 120 (2,8%) cases. The main independent variables associated with mortality were the physiological decline upon admission, massive hemothorax and TT by firearms. The leading cause of death was hypovolemic shock, with significant differences according to the type of TT in the first 4 and 24 hours. In the temporal distribution was observed that, the deaths with penetrating and isolated TT were earlier and that there was no second peak of mortality following the first week. Conclusions: Independent variables associated with mortality were observed among hospitalized patients with TT, being physiological deterioration the most important factor. Besides, there are significant differences in the death causes and temporal distribution of mortality among the different subgroups of hospitalized patients with TT.

Equipos de trauma: realidad mundial e implementación en un país en desarrollo. Descripción narrativa / Trauma teams: global reality and implementation in a developing country. Narrative description

Introducción. El trauma es una de las entidades con mayor morbimortalidad en el mundo. Los equipos especializados en la atención del paciente traumatizado son llamados «equipos de trauma¼. Dichos equipos surgieron de la necesidad de brindar tratamiento oportuno multidisciplinario a individuos con heridas que condicionan gran severidad en la guerra; sin embargo, con el paso del tiempo se trasladaron al ámbito civil, generando un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. El objetivo de este estudio fue describir el proceso de desarrollo de los equipos de trauma a nivel mundial y la experiencia en nuestra institución en el suroccidente colombiano. Métodos. Se realizó una búsqueda en la base de datos PUBMED, que incluyó revisiones sistemáticas, metaanálisis, revisiones de Cochrane, ensayos clínicos y series de casos. Resultados. Se incluyeron 41 estudios para esta revisión narrativa, y se observó que el tiempo de permanencia en Emergencias, el tiempo de traslado a cirugía, la mortalidad y las complicaciones asociadas al trauma fueron menores cuando se implementan equipos de trauma. Discusión. El diseño de un sistema de atención y valoración horizontal de un paciente con traumatismos severos produce un impacto positivo en términos de tiempos de atención, mortalidad y morbilidad. Se hace necesario establecer los parámetros operativos necesarios en las instituciones de salud de alta y mediana complejidad en nuestro país para implementar dichos equipos de trabajo

Introduction. Trauma is one of the entities with the highest morbidity and mortality in the world. Teams specialized in trauma patient care are called «trauma teams¼. These teams arose from the need to provide timely multidisciplinary treatment to individuals with severe injuries in war; however, with time they moved to the civilian arena, generating a positive impact in terms of care times, mortality and morbidity. The objective of this study was to describe the process of development of trauma teams worldwide and the experience in our institution in southwestern Colombia. Methods. A search of the PUBMED database was carried out, which included systematic reviews, metaanalyses, Cochrane reviews, clinical trials, and case series.Results. Forty-one studies were included for this narrative review, and it was observed that the length of stay in the ER, the time of transfer to surgery, mortality and complications associated with trauma were lower when trauma teams are implemented. Discussion. The design of a horizontal care and assessment system for a patient with severe trauma produces a positive impact in terms of care times, mortality and morbidity. It is necessary to establish operational parameters in high and medium complexity health institutions in our country to implement such work teams

Trauma Quality Indicators' usage limitations in severe trauma patients / Limitações do uso de filtros de qualidade para avaliação do atendimento em vítimas de trauma grave

ABSTRACT Purpose: to analyze the relation between Trauma Quality Indicators (QI) and death, as well as clinical adverse events in severe trauma patients. Methods: analysis of data collected in the Trauma Register between 2014-2015, including patients with Injury Severity Score (ISS) > 16, reviewing the QI: (F1) Acute subdural hematoma drainage > 4 hours with Glasgow Coma Scale (GCS) <9; (F2) emergency room transference without definitive airway and GCS <9; (F3) Re-intubation within 48 hours; (F4) Admission-laparotomy time greater than 60 min in hemodynamically instable patients with abdominal bleeding; (F5) Unprogrammed reoperation; (F6) Laparotomy after 4 hours; (F7) Unfixed femur diaphyseal fracture; (F8) Non-operative treatment for abdominal gunshot; (F9) Admission-tibial exposure fracture treatment time > 6 hours; (F10) Surgery > 24 hours. T the chi-squared and Fisher tests were used to calculate statistical relevance, considering p<0.05 as relevant. Results: 127 patients were included, whose ISS ranged from 17 to 75 (28.8 + 11.5). There were adverse events in 80 cases (63%) and 29 died (22.8%). Twenty-six patients had some QI compromised (20.6%). From the 101 patients with no QI, 22% died, and 7 of 26 patients with compromised QI (26.9%) (p=0.595). From the patients with no compromised QI, 62% presented some adverse event. From the patients with any compromised QI, 18 (65.4%) had some adverse event on clinical evolution (p=0.751). Conclusion: the QI should not be used as death or adverse events predictors in severe trauma patients.

RESUMO Objetivo: analisar relação entre comprometimento de Filtros de Qualidade (FQ) com complicações e mortalidade entre vítimas de trauma grave. Métodos: análise dos dados coletados para o Registro de Trauma entre 2014 e 2015, sendo incluídos os traumatizados com Injury Severity Score (ISS) > 16 e analisados os FQ: (F1) drenagem de Hematoma Subdural Agudo (HSA) > 4 horas com Escala de Coma de Glasgow (ECG) <9, (F2) transferência da sala de emergência sem via aérea definitiva e com ECG<9, (F3) reintubação traqueal em até 48 horas, (F4) tempo entre admissão e laparotomia exploradora maior que 60 minutos em pacientes instáveis com foco abdominal, (F5) reoperação não programada, (F6) laparotomia > 4 horas, (F7) fratura de diáfise de fêmur não fixada, (F8) tratamento não operatório em Ferimento por Arma de Fogo (FAF) abdominal, (F9) tempo entre admissão e tratamento de fraturas expostas de tíbia > 6 horas, (F10) operação > 24 horas. Testes de Chi quadrado e Fisher para a análise estatística, considerando significativo p<0,05, foram usados. Resultado: foram incluídos 127 pacientes com ISS entre 17 a 75 (28,8 + 11,5). As complicações ocorreram em 80 casos (63%) e 29 morreram (22,8%). Vinte e seis pacientes apresentaram algum FQ comprometido (20,6%). Dos 101 doentes sem FQ comprometido, 22% faleceram, o que ocorreu em 7 dos 26 doentes com comprometimento dos FQ (26,9%) (p=0,595). Dos doentes sem FQ comprometido, 62% tiveram alguma complicação. Entre os pacientes com FQ comprometido, 18 (65,4%) tiveram complicações (p=0,751). Conclusão: os FQs não devem ser utilizados como preditor de mortes ou complicações evitáveis nas vítimas de traumas graves.

Frequent thoracic injuries and/or findings: hemothorax 127 (62.0%), pneumothorax 96 (46.8%) and pulmonary contusion 51 (24.9%). Definitive treatment: Pleurotomy 88 (42.9%), surgery 71 (34.6%) and medical treatment 46 (22.4%). Median hospitalization 7 days. According TSI: Average ISS 16.7 ± 11.7, average RTS-T 11.1 ± 2.1, average TRISS 9.6. Morbidity: 44 (21.5%). Mortality: 14 (6.8%). There is an increase in polytraumatism and average TRISS, without changes in mortality. Discussion: The majority of TTF were isolated TT. Approximately one third of patients required surgery. The observed mortality is lower than expected. Changes in TTF were observed over time.
