Snappe ii: analysis of accuracy and determination of the cutoff point as a death predictor in a brazilian neonatal intensive care unit / Snappe ii: análise da acurácia e determinação do ponto de corte como preditor de óbito em uma unidade de terapia inensiva neonatal brasileira

ABSTRACT Objective: To analyze the accuracy of the Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II) as a death predictor, to determine the cutoff point for mortality, and to analyze the association of independent variables with death. Methods: Prospective, longitudinal, hospital-based study on newborns admitted to the Neonatal Intensive Care Unit (NICU) for the first time from November 1, 2016 to April 30, 2017. Newborns with less than 12 hours of length of stay at the NICU, out-of-hospital births, major congenital malformations, and inter-hospital transfer were excluded. Variables were grouped according to hierarchical framework, related to maternal characteristics (distal level), prenatal and childbirth care (intermediate level), and birth conditions (proximal level). Descriptive analyses of SNAPPE II score ranges, Receiver Operating Characteristics Curve (ROC curve) to define the cutoff point for mortality, and bivariate analysis by the Wald test and multiple logistic regression were conducted. Results: After selection, the sample consisted of 247 newborns. In this study, the SNAPPE II cutoff point for mortality was 27, with sensitivity of 84.1% and specificity of 82.4%. 61% of those with a score ≥27 died. Multiple logistic regression showed an association between death and proximal-level variables: sepsis (Odds Ratio [OR] 10.68; 95% confidence interval [95%CI] 2.82-40.48; p<0.001); SNAPPE II ≥27 (OR 5.85; 95%CI 1.90-18.05; p=0.002); birth weight 750-999 g (OR 4.15; 95%CI 1.06-16.14; p=0.040); and nonuse of surfactant (OR 0.159; 95%CI 0.04-0.53; p=0.003). Conclusions: Neonatal mortality was directly proportional to increase in SNAPPE II. Score≥27 increased the odds of dying by six times compared with neonates with lower scores. The proximal variables related to health conditions and neonatal care were associated with death.

RESUMO Objetivo: Analisar a acurácia do Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II) como preditor de óbito, determinar o ponto de corte para mortalidade e analisar a associação das variáveis independentes com óbito. Métodos: Estudo prospectivo, longitudinal, de base hospitalar com recém-nascidos admitidos pela primeira vez na Unidade de Terapia Intensiva Neonatal (UTIN) entre 1° de novembro de 2016 e 30 de abril de 2017. Foram excluídos recém-nascidos com permanência menor que 12 horas na UTIN, nascimento extra-hospitalar, malformações congênitas maiores e transferência inter-hospitalar. As variáveis foram agrupadas sob determinação hierarquizada, relacionadas a características maternas (nível distal), assistência ao pré-natal e parto (nível intermediário) e condições do nascimento (nível proximal). Foram conduzidas análises descritivas dos graus de pontuação do SNAPPE II, Receiver Operating Characteristics Curve (curva ROC) para definição do ponto de corte para mortalidade e análise bivariada pelo teste de Wald e regressão logística múltipla. Resultados: Após seleção, a amostra constituiu-se de 247 recém-nascidos. Neste estudo, o ponto de corte do SNAPPE II para mortalidade foi 27, com sensibilidade de 84,1% e especificidade de 82,4%. Evoluíram a óbito 61% daqueles com pontuação ≥27. A regressão logística múltipla mostrou associação entre óbito e variáveis de nível proximal: sepse (Odds Ratio [OR] 10,68; intervalo de confiança de 95% [IC95%] 2,82-40,48; p<0,001); pontuação ≥27 (OR 5,85; IC95% 1,90-18,05; p=0,002); peso ao nascer entre 750 e 999 g (OR 4,15; IC95% 1,06-16,14; p=0,040); e não uso de surfactante (OR 0,159; IC95% 0,04-0,53; p=0,003). Conclusões: A mortalidade neonatal foi diretamente proporcional ao aumento do SNAPPE II. Escore≥27 aumentou seis vezes a chance de óbito em relação aos neonatos com escore inferior. As variáveis proximais relacionadas às condições de saúde e da atenção neonatal associaram-se ao óbito.

Disponibilidade de recursos para tratamento da sepse no Brasil: uma amostra aleatória de instituições brasileiras / Availability of resources to treat sepsis in Brazil: a random sample of Brazilian institutions

RESUMO Objetivo: Caracterizar a disponibilidade de recursos a partir de amostra aleatória representativa das unidades de terapia intensiva do Brasil. Métodos: Realizou-se um questionário estruturado on-line para ser respondido pelo diretor médico de cada unidade participante do estudo SPREAD (Sepsis PREvalence Assessment Database), um estudo de prevalência de um único dia para avaliar o ônus da sepse no Brasil. Resultados: Uma amostra representativa de 277 das 317 unidades convidadas participou por meio de resposta ao questionário estruturado. Em sua maior parte, os hospitais participantes tinham menos que 500 leitos (94,6%), com mediana de 14 leitos na unidade de terapia intensiva. A principal fonte de recursos financeiros para dois terços das unidades pesquisadas era o atendimento de pacientes do sistema público de saúde. Não havia disponibilidade de laboratório de microbiologia próprio em 26,8% das unidades de terapia intensiva pesquisadas, e 10,5% geralmente não tinham acesso à realização de hemoculturas. Em 10,5% das unidades pesquisadas geralmente não estavam disponíveis antibióticos de amplo espectro, e 21,3% das unidades geralmente não podiam obter mensurações de lactato dentro de 3 horas. As instituições com alta disponibilidade de recursos (158 unidades; 57%) eram, em geral, maiores e atendiam principalmente pacientes do sistema de saúde privado. As unidades sem alta disponibilidade de recursos geralmente não dispunham de antibióticos de amplo espectro (24,4%), vasopressores (4,2%) e cristaloides (7,6%). Conclusão: Um número importante de unidades não tem condições para realizar intervenções básicas de monitoramento e terapêutica em pacientes sépticos. Nossos resultados salientam importantes oportunidades que o Brasil tem para melhorar, em termos de adesão a intervenções simples, porém eficazes.

ABSTRACT Objective: To characterize resource availability from a nationally representative random sample of intensive care units in Brazil. Methods: A structured online survey of participating units in the Sepsis PREvalence Assessment Database (SPREAD) study, a nationwide 1-day point prevalence survey to assess the burden of sepsis in Brazil, was sent to the medical director of each unit. Results: A representative sample of 277 of the 317 invited units responded to the resources survey. Most of the hospitals had fewer than 500 beds (94.6%) with a median of 14 beds in the intensive care unit. Providing care for public-insured patients was the main source of income in two-thirds of the surveyed units. Own microbiology laboratory was not available for 26.8% of the surveyed intensive care units, and 10.5% did not always have access to blood cultures. Broad spectrum antibiotics were not always available in 10.5% of surveyed units, and 21.3% could not always measure lactate within three hours. Those institutions with a high resource availability (158 units, 57%) were usually larger and preferentially served patients from the private health system compared to institutions without high resource availability. Otherwise, those without high resource availability did not always have broad-spectrum antibiotics (24.4%), vasopressors (4.2%) or crystalloids (7.6%). Conclusion: Our study indicates that a relevant number of units cannot perform basic monitoring and therapeutic interventions in septic patients. Our results highlight major opportunities for improvement to adhere to simple but effective interventions in Brazil.

Asociación entre el sitio de infección y la mortalidad hospitalaria en pacientes con sepsis atendidos en urgencias de hospitales de tercer nivel en Medellín, Colombia / Association between site of infection and in-hospital mortality in patients with sepsis admitted to emergency departments of tertiary hospitals in Medellin, Colombia

RESUMEN Objetivo: Determinar en pacientes con sepsis admitidos en el servicio de urgencias la asociación entre el foco infeccioso principal y la mortalidad intrahospitalaria como desenlace principal o requerimiento de ingreso a unidad de cuidados intensivos como desenlace secundario. Métodos: Análisis secundario de cohorte prospectiva multicéntrica. Se incluyeron pacientes mayores de 18 años con diagnóstico de sepsis grave o choque séptico atendidos en las salas de urgencias de 3 hospitales de alta complejidad. De 5022 elegibles, se incluyeron 2510 participantes. Análisis de regresión logística múltiple para mortalidad. Resultados: El sitio de infección más frecuente fue tracto urinario, presente en el 27,8% de los casos, seguido de neumonía en el 27,5% y foco intraabdominal en el 10,8%. En el 5,4% de los casos no se identificó foco claro al ingreso. Mediante regresión logística se encontró asociación significativa entre los siguientes sitios de infección y mortalidad intrahospitalaria al tomar como referencia el grupo de infección urinaria: neumonía (OR 3,4; IC95%, 2,2 - 5,2; p < 0,001), piel y tejidos blandos (OR 2,6; IC95%, 1,4 - 5,0; p = 0,003), torrente sanguíneo (OR 2,0; IC95%, 1,1 - 3,6; p = 0,018), sin foco claro (OR 2,0; IC95%, 1,1 - 3,8; p = 0,028), e intraabdominal (OR 1,9; IC95%, 1,1 - 3,3; p = 0,024). Conclusiones: Existe una asociación significativa entre los diferentes sitios de infección y la mortalidad intrahospitalaria o requerimiento de unidad de cuidados intensivos en pacientes con sepsis o choque séptico, siendo la infección de vías urinarias la que confiere el menor riesgo, lo que se deberá tener en cuenta en los modelos pronósticos de estas condiciones.

ABSTRACT Objective: To determine the association between the primary site of infection and in-hospital mortality as the main outcome, or the need for admission to the intensive care unit as a secondary outcome, in patients with sepsis admitted to the emergency department. Methods: This was a secondary analysis of a multicenter prospective cohort. Patients included in the study were older than 18 years with a diagnosis of severe sepsis or septic shock who were admitted to the emergency departments of three tertiary care hospitals. Of the 5022 eligible participants, 2510 were included. Multiple logistic regression analysis was performed for mortality. Results: The most common site of infection was the urinary tract, present in 27.8% of the cases, followed by pneumonia (27.5%) and intra-abdominal focus (10.8%). In 5.4% of the cases, no definite site of infection was identified on admission. Logistic regression revealed a significant association between the following sites of infection and in-hospital mortality when using the urinary infection group as a reference: pneumonia (OR 3.4; 95%CI, 2.2 - 5.2; p < 0.001), skin and soft tissues (OR 2.6; 95%CI, 1.4 - 5.0; p = 0.003), bloodstream (OR 2.0; 95%CI, 1.1 - 3.6; p = 0.018), without specific focus (OR 2.0; 95%CI, 1.1 - 3.8; p = 0.028), and intra-abdominal focus (OR 1.9; 95%CI, 1.1 - 3.3; p = 0.024). Conclusions: There is a significant association between the different sites of infection and in-hospital mortality or the need for admission to an intensive care unit in patients with sepsis or septic shock. Urinary tract infection shows the lowest risk, which should be considered in prognostic models of these conditions.

Assessment of clinical and epidemiological characteristics of patients with and without sepsis in intensive care units of a tertiary hospital / Avaliação das características clínicas e epidemiológicas de pacientes com e sem sepse nas unidades de terapia intensiva de um hospital terciário

ABSTRACT Objective To describe the clinical and epidemiological features of patients with and without sepsis at critical care units of a public hospital. Methods A cross-sectional study was carried out from May 2012 to April 2013. Clinical and laboratory data of patients with and without sepsis in the intensive care units were reviewed of medical records. Results We evaluated 466 patients, 58% were men, median age was 40 years, and 146 (31%) of them were diagnosed with sepsis. The overall mortality was 20% being significantly higher for patients with sepsis (39%). The factors associated with intensive care unit mortality were the presence of sepsis (OR: 6.1, 95%CI: 3.7-10.5), age (OR: 3.6, 95%CI: 1.4-7.2), and length of hospital stay (OR: 0.96, 95%CI: 0.94-0.98). Pulmonary (49%) and intra-abdominal (20%) infections were most commonly identified sites, and coagulase-negative staphylococci and enteric Gram negative bacilli the most frequent (66%) pathogens isolated. Conclusion Although the impact of sepsis on mortality is related to patients' clinical and epidemiological characteristics, a critical evaluation of these data is important since they will allow the direct implementation of local policies for managing this serious public health problem.

RESUMO Objetivo Descrever as características clínicas e epidemiológicas de pacientes com sepse e sem sepse em unidades de cuidados intensivos de um hospital público. Métodos Estudo transversal realizado de maio de 2012 a abril de 2013. Os dados clínicos e laboratoriais de pacientes com sepse e sem sepse das unidades de terapia intensiva foram revisados a partir dos prontuários médicos. Resultados Avaliamos 466 pacientes, 58% homens, mediana de idade 40 anos; sendo 146 (31%) diagnosticados com sepse. A mortalidade global foi 20%, e significativamente maior para pacientes com sepse (39%). Os fatores associados à mortalidade em unidade de terapia intensiva foram a presença de sepse (OR: 6,1, IC95%: 3,7-10,5), idade (OR: 3,6, IC95%: 1,4-7,2) e tempo de internação (OR: 0,96, IC95%: 0,94-0,98). As infecções pulmonares (49%) e intra-abdominais (20%) foram os focos mais comumente identificados, e os estafilococos coagulase-negativa e bacilos entéricos Gram-negativos foram os patógenos isolados mais frequentes (66%). Conclusão Embora o impacto da sepse sobre a mortalidade esteja relacionado às características clínicas e epidemiológicas dos pacientes, uma avaliação crítica desses dados é importante, pois permitirá a implementação direta de políticas locais para gerenciar este grave problema de saúde pública.

RESUMEN Objetivo: Describir la epidemiología de la injuria renal aguda, la relación con la enfermedad renal crónica y los factores asociados a su incidencia. Métodos: Estudio de cohorte y seguimiento en una unidad de terapia intensiva de Montevideo - Uruguay. Se incluyeron pacientes ingresados entre noviembre 2014 a octubre 2015, mayores de 15 años con dos mediciones de creatinina sérica. Se excluyeron pacientes con menos de 48 horas de internación o fallecidos en ese tiempo y portadores de enfermedad renal crónica en hemodiálisis o diálisis peritoneal. No hubo intervenciones. La injuria renal aguda se definió según criterios Acute Kidney Injury Disease Improving Global Outcomes y la enfermedad renal crónica según Cronic Kidney Disease Work Group. Resultados: Se incluyeron 401 pacientes, sexo masculino 56,6%, mediana de edad 68 (rango intercuartílico - RIC 51 - 79) años. El diagnóstico al ingreso fue sepsis grave 36,3%, neurocrítico 16,3%, politrauma 15,2% y otros 32,2%. La incidencia de injuria renal aguda fue de 50,1%. El 14,1% eran portadores de enfermedad renal crónica. La incidencia de injuria renal aguda séptica fue de 75,3%. La mortalidad en los pacientes con o sin injuria renal aguda fue de 41,8 y 14% respectivamente (p < 0,001). En el análisis multivariado las variables de mayor significación para la injuria renal aguda fueron enfermedad renal crónica (odds ratio - OR 5,39 IC95% 2,04 - 14,29 p = 0,001), shock (OR 3,94 IC95% 1,72 - 9,07 p = 0,001) y sepsis grave (OR 7,79 IC 95% 2,02 - 29,97 p = 0,003). Conclusión: La incidencia de injuria renal aguda es elevada principalmente en pacientes sépticos. La enfermedad renal crónica se asoció de forma independiente al desarrollo de injuria renal aguda.

ABSTRACT Objective: To describe the epidemiology of acute kidney injury, its relationship to chronic kidney disease, and the factors associated with its incidence. Methods: A cohort study and follow-up were conducted in an intensive care unit in Montevideo, Uruguay. We included patients admitted between November 2014 and October 2015 who were older than 15 years of age and who had at least two measurements of serum creatinine. We excluded patients who were hospitalized for less than 48 hours, patients who died at the time of hospitalization, and patients with chronic renal disease who were on hemodialysis or peritoneal dialysis. There were no interventions. Acute kidney injury was defined according to the criteria set forth in Acute Kidney Injury Disease: Improving Global Outcomes, and chronic kidney disease was defined according to the Chronic Kidney Disease Work Group. Results: We included 401 patients, 56.6% male, median age of 68 years (interquartile range (IQR) 51-79 years). The diagnosis at admission was severe sepsis 36.3%, neurocritical 16.3%, polytrauma 15.2%, and other 32.2%. The incidence of acute kidney injury was 50.1%, and 14.1% of the patients suffered from chronic kidney disease. The incidence of acute septic kidney injury was 75.3%. Mortality in patients with or without acute kidney injury was 41.8% and 14%, respectively (p < 0.001). In the multivariate analysis, the most significant variables for acute kidney injury were chronic kidney disease (odds ratio (OR) 5.39, 95%CI 2.04 - 14.29, p = 0.001), shock (OR 3.94, 95%CI 1.72 - 9.07, p = 0.001), and severe sepsis (OR 7.79, 95%CI 2.02 - 29.97, p = 0.003). Conclusion: The incidence of acute kidney injury is high mainly in septic patients. Chronic kidney disease was independently associated with the development of acute kidney injury.

Sepsis in a university hospital: a prospective study for the cost analysis of patients' hospitalization / Sepsis en un hospital universitario: estudio prospectivo para análisis de costo de la hospitalización de pacientes / Sepse em um hospital universitário: estudo prospectivo para análise de custo da hospitalização de pacientes

Abstract OBJECTIVE To estimate the cost of hospitalization of patients with severe sepsis or septic shock admitted or diagnosed in the Urgent and Emergency sector at a university hospital and followed until the clinical outcome. METHOD An epidemiological, prospective, observational study conducted in a public hospital in southern Brazil for the period of one year (August 2013 to August 2014). Sepsis notification forms, medical records and data of the cost sector were used for the collection of clinical and epidemiological data. RESULTS The sample comprised 95 patients, resulting in a total high cost of hospitalization (R$ 3,692,421.00), and an average of R$ 38,867.60 per patient. Over half of the total value of the treatment of sepsis (R$ 2,215,773.50) was assigned to patients who progressed to death (59.0%). The higher costs were related to discharge, diagnosis of severe sepsis, the pulmonary focus of infection and the age group of up to 59 years. CONCLUSION The high cost of the treatment of sepsis justifies investments in training actions and institution of protocols that can direct preventive actions, and optimize diagnosis and treatment in infected and septic patients.

Resumen OBJETIVO Estimar el costo de la estancia hospitalaria de pacientes con sepsis severa o choque séptico ingresados o diagnosticados en el sector de Urgencias y Emergencias de un hospital universitario y seguidos hasta el resultado clínico. MÉTODO Estudio epidemiológico, prospectivo y observacional, realizado en un hospital público del sur de Brasil, en el período de 1 año (agosto de 2013 a agosto de 2014). La recolección de los datos clínico-epidemiológicos utilizó fichas de notificación de sepsis, fichas clínicas y datos del sector de costos. Se llevó a cabo análisis de tendencia central, dispersión y cuartiles de los costos de las hospitalizaciones. RESULTADOS Muestra compuesta de 95 pacientes que totalizaron elevado costo de la hospitalización (R$ 3.692.421,00), con promedio de R$ 38.867,60 por paciente. Más de la mitad del valor total del tratamiento de la sepsis (R$ 2.215.773,50) se destinó a pacientes que llegaron a fallecer (59,0%). Los mayores costos estuvieron relacionados con el alta, el diagnóstico de sepsis severa, el foco infeccioso pulmonar y el rango de edad hasta los 59 años. CONCLUSIÓN El elevado costo con el tratamiento de la sepsis justifican inversiones en acciones de capacitación e institución de protocolos que puedan orientar acciones preventivas, optimizar el diagnóstico y la terapéutica en pacientes infectados y sépticos.

Resumo OBJETIVO Estimar o custo da internação de pacientes com sepse grave ou choque séptico admitidos ou diagnosticados no setor de Urgências e Emergências de um hospital universitário e seguidos até o desfecho clínico. MÉTODO Estudo epidemiológico, prospectivo e observacional, realizado em um hospital público do sul do Brasil, no período de 1 ano (agosto de 2013 a agosto de 2014). A coleta dos dados clínico-epidemiológicos utilizou fichas de notificação de sepse, prontuários e dados do setor de custos. Foi realizada análise de tendência central, dispersão e quartis dos custos das internações. RESULTADOS Amostra composta por 95 pacientes que totalizaram elevado custo da internação (R$ 3.692.421,00), com média de R$ 38.867,60 por paciente. Mais da metade do valor total do tratamento da sepse (R$ 2.215.773,50) destinou-se a pacientes que evoluíram a óbito (59,0%). Os maiores custos foram relacionados à alta, ao diagnóstico de sepse grave, ao foco infeccioso pulmonar e à faixa etária até os 59 anos. CONCLUSÃO O elevado custo com o tratamento da sepse justificam investimentos em ações de capacitação e instituição de protocolos que possam direcionar ações preventivas, otimizar o diagnóstico e a terapêutica em pacientes infectados e séptico.

Presión positiva continua en la vía aérea comparada con la respiración mecánica asistida en prematuros de 28 a 32 semanas de gestación con administración precoz de surfactante pulmonar / Nasal CPAP versus mechanical ventilation in 28 to 32-week preterm infants with early surfactant administration

Introducción. La presión positiva continua en la vía aérea ( Continuous Positive Airway Pressure , CPAP) es útil en prematuros de 28 a 32 semanas de gestación con síndrome de dificultad respiratoria, pero no se ha precisado si es mejor que la respiración mecánica asistida después de la administración precoz de surfactante pulmonar. Objetivo. Comparar la incidencia de eventos adversos en prematuros de 28 a 32 semanas de gestación con síndrome de dificultad respiratoria atendidos con surfactante y respiración mecánica asistida o CPAP de burbuja. Materiales y métodos. Se atendieron 147 neonatos con respiración mecánica asistida y 176 con CPAP, ninguno de los cuales presentaba asfixia perinatal o apnea. Resultados. La incidencia de fracaso de la CPAP fue de 6,5 % (IC 95% 11,3-22,8 %). Fallecieron 29 pacientes, 7 de los cuales habían recibido CPAP (4,0 %) y, 22, respiración mecánica asistida (15,0 %; p<0,001). El riesgo relativo (RR) de morir de quienes recibieron CPAP, comparado con el de quienes recibieron respiración mecánica asistida, fue de 0,27 (IC 95% 0,12-0,61), pero, al ajustar por los factores de confusión, el uso de CPAP no implicó mayor riesgo de morir (RR=0,60; IC 95% 0,29-1,24). La letalidad con respiración mecánica asistida fue de 5,70 (IC 95% 3,75-8,66) muertes por 1.000 días-paciente, mientras que con CPAP fue de 1,37 (IC 95% 0,65-2,88; p<0,001). La incidencia de neumopatía crónica fue menor con CPAP (RR=0,71, IC 95% 0,54-0,96), al igual que la de hemorragia cerebral (RR=0,28; IC 95% 0,09-0,84) y la de sepsis (RR=0,67; IC 95% 0,52-0,86), pero fue similar en cuanto a escapes de aire (RR=2,51; IC 95% 0,83-7,61) y enterocolitis necrosante (RR=1,68; IC 95% 0,59-4,81). Conclusión. La incidencia de neumopatía crónica, hemorragia ventricular y sepsis es menor con el uso de CPAP.

Introduction: Continuous positive airway pressure (CPAP) is useful in low birth weight infants with respiratory distress, but it is not known if it is a better alternative to mechanical ventilation after early pulmonary surfactant administration. Objective: To compare the incidence of adverse events in 28 to 32-week newborns with respiratory distress managed with mechanical ventilation or CPAP after early surfactant administration. Materials and methods: In total, 176 newborns were treated with CPAP and 147 with mechanical ventilation, all with Apgar scores >3 at five minutes and without apnea. Results: The incidence of CPAP failure was 6.5% (95% CI: 11.3-22.8%); 29 patients died: 7 with CPAP (4.0%) and 22 with mechanical ventilation (15.0%, p<0.001). The relative risk of dying with CPAP versus mechanical ventilation was 0.27 (95% CI: 0.12-0.61), but after adjusting for confounding factors, CPAP use did not imply a higher risk of dying (RR=0.60; 95% CI: 0.29-1.24). Mechanical ventilation fatality rate was 5.70 (95% CI: 3.75-8.66) deaths/1,000 days-patient, while with CPAP it was 1.37 (95% CI: 0.65-2.88, p<0.001). Chronic lung disease incidence was lower with CPAP than with mechanical ventilation (RR=0.71; 95% CI: 0.54-0.96), as were intracranial hemorrhage (RR=0.28, 95% CI: 0.09-0.84) and sepsis (RR=0.67; 95%CI: 0.52-0.86), and it was similar for air leaks (RR=2.51; 95% CI: 0.83-7.61) and necrotizing enterocolitis (RR=1.68, 95% CI: 0.59-4.81). Conclusion: CPAP exposure of premature infants with respiratory distress syndrome is protective against chronic lung disease, intraventricular hemorrhage and sepsis compared to mechanical ventilation. No differences were observed regarding air leak syndrome or death.

Comparative study of the prevalence of sepsis in patients admitted to dermatology and internal medicine wards / Estudo comparativo da prevalencia de sepse em pacientes internados nas enfermarias de dermatologia e de clinica medica

BACKGROUND: Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis. OBJECTIVES: To evaluate the prevalence of sepsis among patients admitted to a dermatology ward compared to that among patients admitted to an internal medicine ward. METHODS: It is a cross-sectional, observational, comparative study that was conducted at Hospital Santa Casa de Belo Horizonte. Data were collected from all patients admitted to four hospital beds at the dermatology and internal medicine wards between July 2008 and July 2009. Medical records were analyzed for the occurrence of sepsis, dermatologic diagnoses, comorbidities, types of pathogens and most commonly used antibiotics. RESULTS: We analyzed 185 medical records. The prevalence of sepsis was 7.6% among patients admitted to the dermatology ward and 2.2% (p = 0.10) among those admitted to the internal medicine ward. Patients with comorbidities, diabetes mellitus and cancer did not show a higher incidence of sepsis. The main agent found was Staphylococcus aureus, and the most commonly used antibiotics were ciprofloxacin and oxacillin. There was a significant association between sepsis and the use of systemic corticosteroids (p <0.001). CONCLUSION: It becomes clear that epidemiological studies on sepsis should be performed more extensively and accurately in Brazil so that efforts to prevent and treat this serious disease can be made more effectively. .

FUNDAMENTOS: A sepse é causa comum de morbimortalidade em pacientes internados. A sua prevalência está aumentando significativamente em diversas partes do mundo. Pacientes internados em enfermarias de dermatologia apresentam extensas áreas de perda da barreira cutânea, além de uso frequente de corticosteróides sistêmicos, condições favoráveis ao desenvolvimento de sepse. OBJETIVOS: Avaliar a prevalência de sepse em pacientes internados em uma enfermaria de dermatologia e compará-la com a prevalência na enfermaria de clínica médica. MÉTODOS: Trata-se de estudo observacional transversal comparativo de análise de prontuários realizado na Santa Casa de Belo Horizonte. Foram coletados os dados de todos os pacientes internados em quatro leitos da clínica médica e da dematologia no período de julho de 2008 e julho de 2009. Foram analisados em busca da ocorrência de sepse, diagnósticos dermatológicas, comorbidades, tipos de patógenos mais associados e perfil de antibióticos mais utilizados. RESULTADOS: Foram analisados 185 prontuários e a prevalência de sepse entre os pacientes internados na enfermaria de dermatologia foi de 7,6% e na enfermaria de clínica médica 2,2% (p=0,10). Pacientes portadores de comorbidades, diabetes mellitus e neoplasias não demostraram maior ocorrência de sepse. O principal agente encontrado foi Staphylococcus aureus e os antibióticos mais utilizados foram ciprofloxacino e oxacilina. Houve significativa associação de sepse com o uso de corticosteróides sistêmicos (p<0,001). CONCLUSÃO: Torna-se claro que devem ser realizados estudos epidemiológicos mais amplos e acurados no Brasil sobre a sepse, para que os esforços na prevenção e no tratamento dessa grave doença possam ser direcionados ...

Sepse no pós-operatório de cirurgia cardíaca: descrição do problema / Sepsis in the postoperative period of cardiac surgery: problem description

FUNDAMENTOS: A despeito do avanço no diagnóstico e na terapêutica da sepse nos últimos anos, a morbidade e mortalidade são elevadas. OBJETIVO: Avaliar a prevalência, a evolução hospitalar e o prognóstico de pacientes que apresentaram sepse no pós- operatório de cirurgia cardíaca. MÉTODOS: Trata-se de um registro prospectivo que incluiu pacientes (n = 7.332) submetidos à cirurgia cardíaca (valvar ou coronariana) entre janeiro de 1995 e dezembro de 2007. Utilizamos os critérios clássicos de diagnóstico de sepse para identificar os pacientes que evoluíram com tal enfermidade e avaliamos as comorbidades pré-operatórias, a evolução hospitalar e o prognóstico. RESULTADOS: A sepse ocorreu em 29 pacientes (prevalência = 0,39 por cento). O sexo masculino predominou sobre o feminino (79 por cento vs. 21 por cento). A idade média foi de 69 ± 6,5 anos. As principais comorbidades pré-operatórias eram: hipertensão arterial sistêmica (79 por cento), dislipidemia (48 por cento) e antecedente familiar de doença arterial coronariana (38 por cento). O índice Apache médio foi de 18 ± 7, enquanto o Sofa indicou 14,2 ± 3,8. O foco infeccioso primário foi pulmonar em 19 pacientes (55 por cento). Houve 19 culturas positivas, e a média de hidratação endovenosa nas primeiras 24 horas foi de 1.016 ± 803 ml. As principais complicações foram: insuficiência renal aguda (65 por cento), síndrome de baixo débito cardíaco (55 por cento) e arritmia ventricular maligna (55 por cento). A mortalidade foi de 79 por cento (23 pacientes). CONCLUSÃO: A sepse após cirurgia cardíaca foi um evento raro, porém com desfechos clínicos catastróficos. O índice elevado de morbidade e mortalidade revelou a necessidade de um aprimoramento no tratamento, visando melhorar a evolução clínica dos pacientes.

BACKGROUND: In spite of the advances in sepsis diagnosis and treatment in the last years, the morbidity and mortality are still high. OBJECTIVE: To assess the prevalence, in-hospital evolution and prognosis of patients that presented sepsis in the postoperative period of cardiac surgery. METHODS: This is a prospective study that included patients (n = 7,332) submitted to cardiac surgery (valvular or coronary) between January 1995 and December 2007. The classic criteria of sepsis diagnosis were used to identify the patients that developed such condition and the preoperative comorbidities, in-hospital evolution and prognosis were evaluated. RESULTS: Sepsis occurred in 29 patients (prevalence = 0.39 percent). There was a predominance of the male when compared to the female sex (79 percent vs. 21 percent). Mean age was 69 ± 6.5 years. The main preoperative comorbidities were: systemic arterial hypertension (79 percent), dyslipidemia (48 percent) and family history of coronary artery disease (38 percent). The mean Apache score was 18 ± 7, whereas the Sofa score was 14.2 ± 3.8. The primary infectious focus was pulmonary in 19 patients (55 percent). There were 19 positive cultures and the mean IV hydration during the first 24 hours was 1,016 ± 803 ml. The main complications were acute renal failure (65 percent), low cardiac output syndrome (55 percent) and malignant ventricular arrhythmia (55 percent). Mortality was 79 percent (23 patients). CONCLUSION: The occurrence of sepsis after cardiac surgery was a rare event; however, its occurrence showed catastrophic clinical outcomes. The high morbidity and mortality showed the need to improve treatment, aiming at patients' better clinical evolution.

Incidence of bloodstream infection among patients on hemodialysis by central venous catheter / Incidência de infecção da corrente sanguínea nos pacientes submetidos à hemodiálise por cateter venoso central / Incidencia de infección de la corriente sanguínea em los pacientes sometidos a hemodiálisis por catéter venoso central

This study evaluated the incidence and risk factors of bloodstream infection (BSI) among patients with a double-lumen central venous catheter (CVC) for hemodialysis (HD) and identified the microorganisms isolated from the bloodstream. A follow-up included all patients (n=156) who underwent hemodialysis by double-lumen CVC at the Federal University of São Paulo - UNIFESP, Brazil, over a one-year period. From the group of patients, 94 presented BSI, of whom 39 had positive cultures at the central venous catheter insertion location. Of the 128 microorganisms isolated from the bloodstream, 53 were S. aureus, 30 were methicillin-sensitive and 23 were methicillin-resistant. Complications related to BSI included 35 cases of septicemia and 27 cases of endocarditis, of which 15 cases progressed to death. The incidence of BSI among these patients was shown to be very high, and this BSI progressed rapidly to the condition of severe infection with a high mortality rate.

Epidemiology of severe sepsis in the emergency department and difficulties in the initial assistance

BACKGROUND: The aim of this study was to determine the occurrence rate, demographics, clinical characteristics, and outcomes of patients with severe sepsis admitted to the emergency department. METHODS: A prospective study evaluating all patients admitted to the emergency department unit in a public hospital of tertiary complexity in a six-month period was conducted. During this period, the emergency team was trained to diagnose sepsis. Patients who met the diagnostic criteria for severe sepsis were followed until their discharge from the hospital. RESULTS: A total of 5,332 patients were admitted to the emergency department, and 342 met the criteria for severe sepsis/septic shock. The median (interquartile range) age of patients was 74 (65-84) years, and 52.1 percent were male. The median APACHE II and SOFA scores at diagnosis were 19 (15-25) and 5 (3-7), respectively. The median number of dysfunctional organ systems per patient was 2 (1-3). The median hospital length of stay was 10 (4.7-17) days, and the hospital mortality rate was 64 percent. Only 31 percent of the patients were diagnosed by the emergency department team as septic. About 33.5 percent of the 342 severe sepsis patients admitted to the emergency department were referred to an ICU, with a median time delay of 24 (12-48) hours. Training improved diagnosis and decreased the time delay for septic patients in arriving at the ICU. CONCLUSIONS: The occurrence rate of severe sepsis in the emergency department was 6.4 percent, and the rate of sepsis diagnosed by the emergency department team as well as the number of patients transferred to the ICU was very low. Educational campaigns are important to improve diagnosis and, hence, treatment of severe sepsis.

Fatores de risco associados à mortalidade em pacientes com sepse em unidade de terapia intensiva de hospital privado de Pernambuco / Risk factors associated to mortality on septic patients in an intensive care unit of a general private hospital from Pernambuco

JUSTIFICATIVA E OBJETIVOS: Verificar a associação entre as características clínicas, epidemiológicas e laboratoriais com a mortalidade de pacientes com sepse, internados em UTI de hospital privado do estado de Pernambuco (Nordeste do Brasil), a fim de melhorar o atendimento a essa população, através da identificação precoce dos pacientes com risco de desenvolver falência de órgãos. MÉTODO: Estudo de caso-controle aninhado a uma coorte prospectiva e observacional que incluiu os pacientes adultos admitidos na UTI com sepse ou que a desenvolveram durante a internação. Foram colhidos os dados epidemiológicos, avaliados os escores clínicos e exames laboratoriais como: D-dímero, antitrombina III, INR, contagem de plaquetas, sódio, albumina, lactato e creatinina, sendo analisada sua associação com a mortalidade. Os pacientes foram acompanhados até a alta da UTI ou óbito. RESULTADOS: Foram incluídos no estudo 199 pacientes. Após regressão logística, apenas o tempo de internação na UTI maior que 72h, a presença de doença crônica associada, o número de órgãos acometidos superior a três e o lactato maior que 4 mmol/L estiveram associados com a mortalidade. Com relação à associação com o intervalo de tempo para o óbito, apenas o escore SOFA foi significativo, pois um terço dos pacientes com pontuação superior a 12 foram a óbito em menos de 72h. CONCLUSÕES: Os pacientes admitidos com sepse na UTI provenientes da comunidade (tempo de internação hospitalar < 72 horas) apresentaram melhor prognóstico, os pacientes com maior número de órgãos com disfunção apresentaram risco de óbito mais elevado. Laboratorialmente apenas o lactato elevado esteve associado com a mortalidade.

BACKGROUND AND OBJECTIVES: Verify the association between clinical, epidemiological and laboratorial characteristics with mortality of septic patient in an Intensive Care Unit (ICU) from Pernambuco, northeast of Brazil, to improve the attention for patients with sepse which are in risk of developing organ dysfunction. METHODS: Case-control study, without intervention, that included adults' patients admitted in ICU with sepsis or that developed it during ICU stay. RESULTS: It was included 199 patients. After logistic regression, the length of hospital stay more than 72 hours before admission in ICU, evidence of associated co-morbidities, more than three organ failures, and lactate more than 4 mmol/L were associated with mortality. The SOFA score with more than 12 points was associated with precocity mortality (< 72hours). CONCLUSIONS: The septic patients admitted ICU with less than 72h of hospital stay have a better prognosis, and those with a great number of organ failure, and co-morbidities have a superior mortality rate. Between laboratory results, only the high concentration of lactate is associated with mortality.

Etiology and pathogenesis of bloodstream infections associated with the use of long-term central vascular catheter (CVC) in patients who undergone gastrointestinal surgery

CVC is the main factor of risk of bloodstream infections. This study purpose was determining both etiology and pathogenesis of these infections in 80 patients who undergone gastrointestinal surgery and who worn long lasting CVC, in the institution HC-UFU. Cultures were made in nostril, skin of the insertion site, tip and catheter hub, in addition to hemoculture in those suspects of sepsis. The colonization incidence rate of the catheter tip was 12.5/ 1,000 catheter days and the CVC associate infection rate was 3.1/1,000 catheter days. Frequencies of skin, hub and catheter tip colonization were 13.8 percent, 8.9 percent and 13.3 percent, respectively. Coagulase-negative Staphylococci were the most found microorganisms in nostril (74 percent), skin (45.4 percent) and hub (75 percent) and Gram-negative bacilli (50 percent), followed by S. aureus (25 percent) the most common ones in catheter tip. Approximately 51 percent of patients received antibiotics and most of them (53.7 percent) had therapeutic purpose. The frequency of patients with clinical sepsis was 27.5 percent. Three cases of bacteremia associated with the use of CVC were detected (3.8 percent), with S. aureus in two of them and K. pneumoniae in the third one. There was not seen any association of skin and hub colonization with their presence in the catheter tip and in the blood of these patients, but S. aureus was recovered from nostril of those with sepsis by this pathogenic agent. A greater concern is suggested over preventive measures and control of these primary and secondary bloodstream, as well as catheter tip colonization.

Risk factors for anastomotic leakage after preoperative chemoradiation therapy and low anterior resection with total mesorectal excision for locally advanced rectal cancer / Factores de riesgo para la fuga anastomótica después de quimio-radioterapia preoperatoria y resección anterior baja con excisión total de mesorrecto para cáncer de recto localmente avanzado

Background. Risk factors for anastomotic leakage after preoperative chemoradiation plus low anterior resection and total mesorectal excision remain uncertain. Objective. To analyze, the associated risk factors with colorectal anastomosis leakage following preoperative chemo-radiation therapy and low anterior resection with total mesorectal excision for rectal cancer. Materials and methods. Between January 1992 and December 2000, 92 patients with rectal cancer were treated with 45 Gy of preoperative radiotherapy and bolus infusion of 5-FU 450 mg/m² on days 1-5 and 28-32, six weeks later low anterior resection was performed. Univariate analysis was performed as to find the risk factors for colorectal anastomotic leakage. Results. There were 48 males and 44 females, mean age was 55.8 years. Mean tumor location above the anal verge was 7.4 ± 2.6 cm. Preoperative mean levels of albumin and lymphocytes were 3.8 g/dL and l,697/mL, respectively. Mean distal margin was 2.9 ± 1.4 cm. Multivisceral resection was performed in 11 patients (13.8%), 32 patients (35%) had diverting stoma. Mean preoperative hemorrhage was 577 ± 381 mL, and 27 patients (24%) received blood transfusion. Ten patients (10.9%) had anastomotic leakage. No operative mortality occurred. Risk factors for anastomotic leakage were: gender (male) and tumor size > 4 cm. Three patients of the group without colostomy required a mean of six days in the unit of intensive care; mean time of hospital stay of patients with and without protective colostomy was 12.4 ± 4.5 days vs. 18.3 ± 5.2 days (p = 0.01). Conclusion. In male patients with rectal adenocarcinoma measuring > 4 cm, treated by preoperative chemoradiotherapy + low anterior resection with total mesorectal excision, a diverting stoma should be performed to avoid major morbidity due to anastomotic leak.

Antecedentes. Los factores de riesgo para la fuga de anastomosis colo-rectal después de quimio-radioterapia preoperatoria con excisión total de mesorrecto permanecen aún inciertos. Objetivo. Analizar los factores de riesgo asociados con la fuga o filtración de anastomosis colorrectal que sigue a la terapia de radiación química y a la extirpación anterior baja con total excisión mesorrectal para el cáncer rectal. Materiales y métodos. Entre enero de 1992 y diciembre de 2000, 92 pacientes con cáncer rectal fueron tratados con 45 Gy de radioterapia preoperativa e infusión del bolo de 5'FU450 mg/m² administrados los días 1-5 y del 28-32; seis semanas más tarde, se realizó la extirpación anterior baja. Se llevó a cabo un análisis univariado en cuanto a encontrar los factores de riesgo de la fuga anastomótica colorrectal. Resultados. Se trató a 48 varones y 44 mujeres cuya media etaria fue de 55.8 años. La localización media del tumor arriba del borde anal fue de 7.4 ± 2.6 cm. Los niveles medios preoperativos de albúmina y linfocitos fueron de 3.8 g/dL y 1,697/mL, respectivamente. El margen distal medio fue de 2.9 ± 1.4 cm. La extirpación multivisceral fue realizada en 11 pacientes (13.8%); 32 pacientes (35%) tuvieron una colostomía derivativa. La hemorragia preoperativa media fue de 577 ± 381 mL, y 27 pacientes (24%) recibieron transfusión sanguínea. Diez pacientes (10.9%) tuvieron fuga anastomótica. No hubo ningún deceso quirúrgico. Los factores de riesgo para la fuga anastomótica fueron: el género (masculino) y el tamaño del tumor > 4 cm. Tres pacientes del grupo sin colostomía requirieron una media de seis días en la UTI (Unidad de Terapia Intensiva); el promedio media de la duración hospitalaria de pacientes con y sin colostomía protectiva fue de 12.4 ± 4.5 días contra 18.3 ± 5.2 días (p = 0.01). Conclusión. En pacientes masculinos con adenocarcinoma rectal que mide > 4 cm, tratados mediante radioterapia química preoperativa + extirpación anterior baja con excisión total mesorrectal, debería realizarse una abertura que se desvíe a fin de evitar una mayor mortalidad debida a fuga anastomótica.

Características da população com sepse em unidade de terapia intensiva de hospital terciário e privado da cidade do Recife / Characteristics of septic patients in an intensive care unit of a tertiary private hospital from Recife, northeast of Brazil

JUSTIFICATIVA E OBJETIVOS: Determinar as características clínicas, epidemiológicas e laboratoriais, bem como a mortalidade dos pacientes adultos com sepse, admitidos na UTI geral de hospital privado terciário do estado de Pernambuco. MÉTODO: Estudo tipo coorte prospectiva e observacional, que incluiu pacientes adultos admitidos com o diagnóstico de sepse ou que a desenvolveram durante a internação na UTI do Hospital Português de Recife durante o período de seis meses. Foram colhidos dados clínicos e laboratoriais, bem como, calculados os escores APACHE II e SOFA, sendo os pacientes re-avaliados ao final da internação para definir o desfecho clínico, ou seja, para alta, óbito, ou transferência da UTI. RESULTADOS: Foram incluídos 199 pacientes, dos quais 112 (56,3 por cento) tiveram alta da UTI. Cerca de 67,8 por cento da população foi composta por idosos (maiores de 65 anos), a média do APACHE II foi de 18,2 ± 6,3 e a média do SOFA no primeiro dia foi de 6,3 ± 3,7. O motivo da internação foi clínico em 85,4 por cento dos casos e em 76,4 por cento dos pacientes existia doença crônica associada. A sepse foi de origem pulmonar em 79,3 por cento dos casos e 40 por cento dos pacientes tiveram o agente etiológico isolado. Observou-se plaquetopenia (plaquetas < 100.000/mm³) em 20,6 por cento dos pacientes, o INR > 1,5 em 42 por cento, o fibrinogênio > 300 mg/dL em 81,7 por cento e a atividade da antitrombina < 70 por cento em 32,5 por cento dos casos. CONCLUSÕES: Os dados epidemiológicos de sepse nesse estudo são semelhantes àqueles recentemente descritos em populações no Sul e Sudeste do Brasil, bem como dos Estados Unidos e Europa.

BACKGROUND AND OBJECTIVES: Establish the clinical, epidemiological and laboratorial characteristics of septic patients in an intensive care unit (ICU) of a tertiary care private hospital from Pernambuco, in the northeast of Brazil. METHODS: Cohort study without intervention that included adult patients admitted in the ICU with sepsis or that developed it during ICU stay, during a 6-month period. The patients were followed during all ICU stay period. Laboratory and clinical data were collected after sepsis diagnosis. ICU admission APACHE II score and the SOFA score during the three first days after inclusion in the study were collected. RESULTS: The study included 199 patients, of whom 67.8 percent were older than 65 years of age. More than a half (56.3 percent) survived the septic episode, mean APACHE II was 18.2 ± 6.3 and mean SOFA score was 6.3 ± 3.7. The disease related to the admission in ICU was medical in 85.4 percent, and the majority of patients had a chronic associated disease. In 79.3 percent the lungs were the source of sepsis and in 40 percent of patients the etiologic agent of sepsis was isolated. Amongst laboratory tests, thrombocytopenia (platelets < 100.000/mm³) was observed on 20.6 percent, fibrinogen was elevated (> 300 mg/dL) on 81.7 percent, and the activity of antithrombin was low (< 70 percent) on 32.5 percent of patients. CONCLUSIONS: The epidemiology of sepsis in this study, in a private hospital of Recife, was no different from what was recently described in Southeast and South of Brazil, United States and Europe.

SRIS, sepsis y SDOM: una visión quirúrgica / Systemic inflammatory response syndrome, sepsis and dysfunction multiorganic syndrome: asurgical point of view

En la práctica quirúrgica diaria es cada vez más frecuente encontrar pacientes en estado crítico, con cuadros de sepsis. CDC (Centers for Disease Control and Preventions) estima que la incidencia de sepsis ha ido en aumento: de 73,6 por 100.000 habitantes en 1979 a 175,9 por 100.000 habitantes en 1989. Este aumento puede ser debido al aumento de uso de fármacos citotóxicos e inmunodepresores, el aumento de la edad de la población, el aumento de infecciones por gérmenes resistentes a antibióticos y el aumento en el uso de dispositivos invasivos como catéteres intravasculares. En este artículo se revisan las definiciones más importantes acerca de éste tema, dos de los principales escores de gravedad y disfunción multiorgánica (APACHE II y SOFA) y las medidas terapéuticas que han demostrado mejorar el pronóstico en éste grupo de pacientes.
