Prediction of adverse drug reactions in geriatric patients admitted to intensive care units. / [Artículo traducido] Predicción de reacciones adversas a medicamentos en pacientes geriátricos ingresados en unidades de cuidados intensivos.

INTRODUCTION: Intensive Care Units (ICUs) pose challenges in managing critically-ill patients with polypharmacy, potentially leading to Adverse Drug Reactions (ADRs), particularly in the elderly. OBJECTIVE: To evaluate whether the severity and clinical prognosis scores used in ICUs correlate with the prediction of ADRs in aged patients admitted to an ICU. METHODS: A cohort study was conducted in a Brazilian University Hospital ICU. APACHE II and SAPS 3 assessed clinical prognosis, while GerontoNet ADR Risk Score and BADRI evaluated ADR risk at ICU admission. Severity of the patients' clinical conditions was evaluated daily based on the SOFA score. Adverse Drug Reaction (ADR) screening was performed daily through the identification of ADR triggers. RESULTS: 1295 triggers were identified (median 30 per patient, IQR = 28), with 15 suspected ADRs. No correlation was observed between patient severity and ADRs at admission (p=0.26), during hospitalization (p=0.91), or at follow-up (p=0.77). There was also no association between death and ADRs (p=0.28) or worse prognosis and ADRs (p>0.05). Higher BADRI scores correlated with more ADRs (p=0.001). CONCLUSIONS: The data suggest that employing the severity and clinical prognosis scores used in Intensive Care Units is not sufficient to direct active pharmacovigilance efforts, which are therefore indicated for critically ill patients.

Oxygen Debt as Predictor of Mortality and Multiple Organ Dysfunction Syndrome in Severe COVID-19 Patients: A Retrospective Study.

Background: Oxygen debt (DEOx) represents the disparity between resting and shock oxygen consumption (VO2) and is associated with metabolic insufficiency, acidosis, severity, and mortality. This study aimed to assess the reliability of DEOx as an indirect quantitative measure for predicting multiple organ dysfunction syndrome (MODS) and 28-day mortality in patients admitted to the intensive care unit (ICU) with respiratory syndrome severe acute coronavirus type 2 (SARS-CoV-2) infection, in comparison to the Acute Physiology and Chronic Health Evaluation II (APACHE II), sepsis-related organ failure assessment (SOFA), and 4C scores. Methods: A retrospective cohort study was conducted, including ICU patients with SARS-CoV-2 infection between 2020 and 2021. Clinical data were extracted from the EPIMED Monitor Database®. APACHE II, SOFA, and 4C scores were calculated upon ICU admission, and their accuracy in predicting 28-day mortality and MODS was compared to DEOx. Multivariate logistic regression analysis was performed to analyze the outcome variables. Results: 708 patients were included, with a mortality rate of 44.4%. DEOx value was 11.16 ml O2/kg. The mean age was 58.7 years. Multivariate analysis showed that DEOx was independently associated with mortality, intubation, and renal injury. Each point increase in creatinine was associated with a higher risk of MODS. To determine the precision of the scores, area under the receiver operating characteristic curves (AUROC) analysis was performed with weak discrimination and similar behavior for the primary outcomes. The most accurate scale for mortality and MODS was 4C with an AUC of 0.683 and APACHE II with an AUC of 0.814, while that of the AUROC of DEOx was 0.612 and 0.646, respectively. Conclusions: DEOx showed similar predictive value to established scoring systems in critically ill patients with SARS-CoV-2 infection. The correlation of DEOx with these scores may facilitate early intervention in critically ill patients.

Acute-on-chronic liver failure is independently associated with higher mortality for cirrhotic patients with acute esophageal variceal hemorrhage: Retrospective cohort study.

BACKGROUND: Acute esophageal variceal hemorrhage (AEVH) is a common complication of cirrhosis and might precipitate multi-organ failure, causing acute-on-chronic liver failure (ACLF). AIM: To analyze if the presence and grading of ACLF as defined by European Society for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) is able to predict mortality in cirrhotic patients presenting AEVH. METHODS: Retrospective cohort study executed in Hospital Geral de Caxias do Sul. Data from medical records from 2010 to 2016 were obtained by searching the hospital electronic database for patients who received terlipressin. Medical records were reviewed in order to determine the diagnosis of cirrhosis and AEVH, including 97 patients. Kaplan-Meier survival analysis was used for univariate analysis and a stepwise approach to the Cox regression for multivariate analysis. RESULTS: All- cause mortality for AEVH patients was 36%, 40.2% and 49.4% for 30-, 90- and 365-day, respectively. The prevalence of ACLF was 41.3%. Of these, 35% grade 1, 50% grade 2 and 15% grade 3. In multivariate analysis, the non-use of non-selective beta-blockers, presence and higher grading of ACLF and higher Model for End-Stage Liver Disease scores were independently associated with higher mortality for 30-day with the addition of higher Child-Pugh scores for 90-day period. CONCLUSION: Presence and grading of ACLF according to the EASL-CLIF criteria was independently associated with higher 30- and 90-day mortality in cirrhotic patients admitted due to AEVH.

[Correlation between the shock index and the anaerobic index]. / Correlación entre el índice de choque y el índice anaerobio.

Background: Shock is defined as an acute circulatory insufficiency that causes cellular dysfunction. The shock index (SI) and the anaerobic index or the relationship between the veno-arterial gradient of carbon dioxide and the difference between the arterial and venous content of O2 [∆P(v-a)CO2/ΔC(a-v)O2] are markers of systemic hypoperfusion. Objective: To determine if there is a correlation between the SI and the anaerobic index in patients with circulatory shock. Material and methods: Observational and prospective study in patients with circulatory shock. The SI and the anaerobic index were calculated at admission to the intensive care unit (ICU) and during their stay. Pearson's correlation coefficient was calculated and the association of SI with mortality was explored with bivariate logistic regression. Results: 59 patients aged 55.5 (± 16.5) years, 54.3% men, were analyzed. The most frequent type of shock was hypovolemic (40.7%). They had SOFA score: 8.4 (± 3.2) and APACHE II: 18.5 (± 6). The SI was: 0.93 (± 0.32) and the anaerobic index: 2.3 (± 1.3). Global correlation was r = 0.15; at admission r = 0.29; after 6 hours: r = 0.19; after 24 hours: r = 0.18; after 48 hours: r = 0.44, and after 72 hours: r = 0.66. The SI > 1 at ICU admission had an OR 3.8 (95% CI: 1.31-11.02), p = 0.01. Conclusions: The SI and the anaerobic index have a weak positive correlation during the first 48 hours of circulatory shock. The SI > 1 is a possible risk factor for death in patients with circulatory shock.

Introducción: el choque se define como una insuficiencia circulatoria aguda que ocasiona disfunción celular. El índice de choque (ICh) y el índice anaerobio o relación entre el gradiente veno-arterial de dióxido de carbono y la diferencia entre el contenido arterial y venoso de O2 [∆P(v-a)CO2/ΔC(a-v)O2] son marcadores de hipoperfusión sistémica. Objetivo: determinar si existe correlación entre el ICh y el índice anaerobio en pacientes con choque circulatorio. Material y métodos: estudio observacional y prospectivo en pacientes con choque circulatorio. Se calcularon el ICh y el índice anaerobio al ingreso a la unidad de cuidados intensivos (UCI) y durante su estancia. Se calculó el coeficiente de correlación de Pearson y se exploró la asociación del ICh con la mortalidad con una regresión logística bivariada. Resultados: se analizaron 59 pacientes de 55.5 (± 16.5) años, 54.3% hombres. El tipo de choque más frecuente fue el hipovolémico (40.7%). Tuvieron puntaje SOFA: 8.4 (± 3.2) y APACHE II: 18.5 (± 6). El ICh fue: 0.93 (± 0.32) y el índice anaerobio: 2.3 (± 1.3). La correlación global fue r = 0.15; al ingreso: r = 0.29; a las 6 horas: r = 0.19; a las 24 horas: r = 0.18; a las 48 horas: r = 0.44, y a las 72 horas: r = 0.66. El ICh > 1 al ingreso a la UCI tuvo una RM 3.8 (IC 95%: 1.31-11.02), p = 0.01. Conclusiones: el ICh y el índice anaerobio tienen una correlación positiva débil durante las primeras 48 horas del choque circulatorio. El ICh > 1 es un posible factor de riesgo de muerte en pacientes con choque circulatorio.

Validation of low anterior resection syndrome score in Brazil with Portuguese.

PURPOSE: This study was performed to investigate the convergent validity, discriminative validity, and reliability of the Brazilian version of the low anterior resection syndrome (LARS) score in a population with low educational and socioeconomic levels. METHODS: The LARS score was translated into the Portuguese language by forward- and back-translation procedures. In total, 127 patients from a public hospital in Brazil completed the questionnaires. The convergent validity was tested by comparing the LARS score with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core Module 30 (QLQ-C30) and with patients' self-reported quality of life. For the discriminative validity, we tested the ability of the score to differentiate among subgroups of patients regarding neoadjuvant radiotherapy, type of surgery, and tumor distance from the anal verge. The test-retest reliability was investigated in a subgroup of 36 patients who responded to the survey twice in 2 weeks. RESULTS: The LARS score demonstrated a strong correlation with 5 of 6 items from the EORTC QLQ-C30 (P<0.05) and good concordance with patients' self-reported quality of life (95.3%), confirming the convergent validity. The score was able to discriminate between subgroups of patients with different clinical characteristics related to LARS (P<0.001). The agreement between the test and retest showed that 86.1% of the patients remained in the same LARS category, and there was no significant difference between the LARS score numerical values (P=0.80), indicating good reliability overall. CONCLUSION: The Brazilian version of the LARS score is a valid and reliable instrument to assess postoperative bowel function in a population with low educational and socioeconomic levels.

Abstract Objective To analyze the predictors of mortality and the average survival time of patients hospitalized in Intensive Care Units. Methods This is a prospective cohort, carried out from August 2018 to July 2019, in four adult Intensive Care Units (ICU) from the public and private network of the State of Sergipe. All adult patients were included, provided they had a minimum length of stay of 24 hours in the unit. The primary outcome was death. Secondary outcomes were dialysis, pressure injury, Acute Kidney Injury, need for invasive mechanical ventilation for more than 48 hours, infection, and length of hospital stay. Results Of the 432 patients, there was a predominance of death in male patients, older and coming from the emergency unit. The presence of heart failure, creatinine values >1.5 mg/dL at admission, diabetes mellitus, liver disease and smoking were also associated with the death outcome. As for the other predictors, the longest hospital stay, higher Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology (SAPS 3) and Nursing Activities Score (NAS) scores, in addition to the use of noradrenaline, stand out. The use of fentanyl was associated with increased survival time and the overall median survival time was 28 days. Conclusion The mortality predictors of patients admitted to the ICU in Sergipe were longer length of stay; the highest SOFA, SAPS-3 and NAS scores; creatinine >1.5mg/dl on admission; use of vasopressor drugs and the need for dialysis.

Neonatal Sequential Organ Failure Assessment as a late-onset sepsis mortality predictor in very low birth weight newborns: a Brazilian cohort study.

Death is a frequent occurrence in late-onset neonatal sepsis (LOS). We aimed to evaluate if the Neonatal Sequential Organ Failure Assessment (nSOFA) is associated with mortality due to LOS in very low birth weight (VLBW) infants. This is a single-center Brazilian cohort study including VLBW infants admitted between 2006 and 2020 who were diagnosed with LOS caused by Staphylococcus aureus, Enterococcus sp or Gram-negative bacteria. The primary outcome was mortality associated with sepsis. Two groups of patients-survivors and non-survivors-were compared regarding descriptive maternal and neonatal variables and the nSOFA score, evaluated at nine moments, from 48 hours before the diagnosis of sepsis to 48 hours later (T-48, T-24, T-12, T-6, T0, T+6, T+12, T+24, T+48). Diagnostic accuracy was expressed as the area under the curve (AUC). Among the 1574 VLBW infants hospitalized in the period, 114 episodes of culture-confirmed LOS occurred. There were 21 sepsis-related deaths (18.4%), mostly from Gram-negative bacteria and Enterococcus sp. There were no statistically significant differences between the groups regarding maternal and neonatal variables. Median nSOFA was significantly higher in the non-survivor group at all time points (range 2 to 13 versus 1 to 3). In the logistic regression analysis, each increment of one point in the score significantly increases the risk of death in eight of the nine moments, but no difference was found in T-24. Time T-6 had the best accuracy (88.1%).   Conclusion: The nSOFA score was significantly associated with the risk of death from LOS in VLBW infants. What is Known: • The neonatal sepsis may result in organ dysfunction and death, and it is important to find indicators that could identify this clinical progression. • The nSOFA score was proposed in 2020 to predict mortality from LOS, but since it is recent and still in the research phase, further studies are important to improve it before being widely used in clinical practice. What is New: • We showed a significative association between higher nSOFA scores and mortality. Our results corroborate the validity and the importance of the nSOFA score and highlight its high NPV.

Ética do uso de escores prognósticos em unidade de terapia intensiva: revisão integrativa / Ethics in the use of prognostic scores in intensive care units: an integrative review / Ética del uso de puntajes pronósticos en una unidad de cuidados intensivos: una revisión integradora

Resumo O enfrentamento da covid-19 suscitou uma série de problemas na área da saúde, em razão do aumento da demanda de cuidados intensivos. Para solucionar a crise causada pela escassez de recursos de alta complexidade, a tomada de decisão tem se norteado por escores prognósticos, porém esse processo inclui uma dimensão moral, ainda que esta seja menos evidente. Mediante revisão integrativa, este artigo buscou refletir sobre a razoabilidade da utilização de indicadores de gravidade para definir a alocação de recursos escassos na saúde. Observou-se que o trabalho realizado em situações de escassez de recursos provoca sobrecarga moral, convergindo para busca por soluções padronizadas e objetivas, como a utilização de escores prognósticos. Conclui-se que seu uso isolado e indiscriminado não é eticamente aceitável e merece avaliação cautelosa, mesmo em situações emergenciais, como a da covid-19.

Abstract Facing COVID-19 caused many problems in the healthcare field, due to the rise in the intensive care demand. To solve this crisis, caused by the scarcity of resources of high complexity, decision-making has been guided by prognostic scores; however, this process includes a moral dimension, although less evident. With na integrative review, this article sought to reflect on the reasonability of using severity indicators to define the allocation of the scarce resources in healthcare. We observed that the work carried out on resource scarcity situations causes moral overload, converging to the search for standard and objective solutions, such as the use of prognostic scores. We conclude that their isolated and indiscriminate use is not ethically acceptable and deserves cautious evaluation, even in emergency situations, such as COVID-19.

Resumen La lucha contra el Covid-19 implicó una serie de problemas en el área de la salud, debido al aumento de la demanda de cuidados intensivos. Para solucionar la crisis provocada por la escasez de recursos de alta complejidad, la toma de decisiones estuvo orientada por puntuaciones pronósticas, pero este proceso incluye una dimensión moral aún menos evidente. A partir de una revisión integradora, este artículo buscó reflexionar sobre la razonabilidad de utilizar indicadores de gravedad para definir la asignación de recursos escasos en salud. El trabajo realizado en situaciones de escasez de recursos genera sobrecarga moral, llevando a la búsqueda de soluciones estandarizadas y objetivas, como el uso de puntuaciones de pronóstico. Se concluye que su uso aislado e indiscriminado no es éticamente aceptable y merece una cuidadosa evaluación, incluso en situaciones de emergencia, como la del Covid-19.

Correlação entre níveis de sindecano 1, escore PELOD-2 e mortalidade em sepse pediátrica / Correlation between syndecan-1 level and PELOD-2 score and mortality in pediatric sepsis

RESUMO Objetivo: Analisar a correlação entre a lesão do glicocálix medida pelo nível sérico de sindecano 1 e as disfunções de órgãos avaliadas com o escore PELOD-2, assim como avaliar sua associação com a mortalidade em sepse pediátrica. Métodos: Realizou-se um estudo prospectivo observacional em um hospital terciário público. Sessenta e oito pacientes pediátricos, com diagnóstico de sepse segundo os critérios da International Pediatric Sepsis Consensus Conference, foram consecutivamente recrutados. Nos dias 1 e 5, realizaram-se dosagens dos níveis séricos de sindecano 1 e avaliação dos componentes do escore PELOD-2. Os pacientes foram seguidos por até 28 dias após o diagnóstico de sepse. Resultados: Em geral, o nível de sindecano 1 estava aumentado em todos os participantes, com nível significantemente mais elevado nos pacientes em choque (p = 0,01). O nível de sindecano 1 no dia 1 teve correlação positiva com o escore PELOD-2 no dia 1 e coeficiente de correlação de 0,35 (p = 0,003). Nos primeiros 5 dias após o diagnóstico de sepse, as alterações nos níveis de sindecano 1 tiveram correlação positiva com modificações no escore PELOD-2, com coeficiente de correlação de 0,499 (p < 0,001). Com utilização de um ponto de corte dos níveis de sindecano 1 no dia 1 ≥ 430ng/mL, a disfunção de órgãos (escore PELOD-2 ≥ 8) pôde ser predita com área sob a curva de 74,3%, sensibilidade de 78,6% e especificidade de 68,5% (p = 0,001). Conclusão: O nível de sindecano 1 no dia 1 teve correlação com o escore PELOD-2 no dia 1, porém não se associou com a mortalidade aos 28 dias. A disfunção de órgãos (PELOD-2 ≥ 8) pôde ser predita pelo nível de sindecano 1 nas primeiras 24 horas de sepse, sugerindo seu significante envolvimento na fisiopatologia da disfunção de órgãos associada à sepse.

ABSTRACT Objective: To analyze the correlation between glycocalyx disruption measured via the serum syndecan-1 level and organ dysfunctions assessed by the PELOD-2 score and to evaluate its association with mortality in pediatric sepsis. Methods: We performed a prospective observational study in a tertiary public hospital. Sixty-eight pediatric patients diagnosed with sepsis according to International Pediatric Sepsis Consensus Conference criteria were consecutively recruited. We performed measurements of day 1 and day 5 serum syndecan-1 levels and PELOD-2 score components. Patients were followed up to 28 days following sepsis diagnosis. Results: Overall, the syndecan-1 level was increased in all subjects, with a significantly higher level among septic shock patients (p = 0.01). The day 1 syndecan-1 level was positively correlated with the day 1 PELOD-2 score with a correlation coefficient of 0.35 (p = 0.003). Changes in syndecan-1 were positively correlated with changes in the PELOD-2 score, with a correlation coefficient of 0.499 (p < 0.001) during the first five days. Using the cutoff point of day 1 syndecan-1 ≥ 430ng/mL, organ dysfunction (PELOD-2 score of ≥ 8) could be predicted with an AUC of 74.3%, sensitivity of 78.6%, and specificity of 68.5% (p = 0.001). Conclusion: The day 1 syndecan-1 level was correlated with the day 1 PELOD-2 score but not 28-day mortality. Organ dysfunction (PELOD-2 ≥ 8) could be predicted by the syndecan-1 level in the first 24 hours of sepsis, suggesting its significant pathophysiological involvement in sepsis-associated organ dysfunction.

Insuficiência hepática crônica agudizada está independentemente associada com menor sobrevida em pacientes com peritonite bacteriana espontânea / Acute-on-chronic liver failure is independently associated with lower survival in patients with spontaneous bacterial peritonitis

ABSTRACT BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a decompensation of cirrhosis with an in-hospital mortality ranging from 20% to 40%. OBJECTIVE: The purpose of this study is to analyze if EASL-CLIF definition of acute-on-chronic liver failure (ACLF) is able to predict mortality in cirrhotic patients with SBP. METHODS: Historical cohort study conducted in a public tertiary care teaching hospital. Data from medical records from January 2009 to July 2016 were obtained by searching the hospital electronic database for samples of ascites collected in the period. Electronic and physical medical records were analyzed and patients were included if they were over 18-years old, with cirrhosis and an ascites fluid compatible with SBP: 69 patients were included. Liver-specific scores were calculated and Kaplan-Meier survival analysis was used for univariate analysis and a stepwise approach to the Cox regression for multivariate analysis. RESULTS: All cause mortality was 44%, 56.5% and 74% for 28-, 90- and 365-day, respectively. The prevalence of ACLF was 58%. Of these, 65% grade 1, 17.5% grade 2 and 17.5% grade 3. In multivariate analysis, the use of proton-pump inhi­bitors, alanine transaminase lower than 40 U/L, hemoglobin higher than 9 g/dL, absence of ACLF and lower CLIF-SOFA and MELD scores were independently associated with higher survival for both 28- and 90-day interval. CONCLUSION: The presence of ACLF and higher CLIF-SOFA scores were independently associated with higher 28- and 90-day mortality in cirrhotic patients admitted due to SBP.

RESUMO CONTEXTO: A peritonite bacteriana espontânea (PBE) é uma descompensação da cirrose com uma mortalidade intra-hospitalar de 20% a 40%. OBJETIVO: O objetivo deste estudo é analisar se a definição de insuficiência hepática crônica agudizada (IHCA) como definido pelo consórcio EASL-CLIF é capaz de predizer mortalidade em pacientes cirróticos com PBE. MÉTODOS: Coorte histórica conduzida em um hospital de ensino público terciário. Foram obtidos dados de prontuários médicos de janeiro de 2009 até julho de 2016, buscando no banco de dados eletrônico do hospital por todas as amostras de ascite coletadas no período. Prontuários eletrônicos e físicos foram analisados e os pacientes com mais de 18 anos com cirrose e líquido de ascite compatível com PBE foram incluídos. Foram incluídos 69 pacientes. Escores específicos para o fígado foram calculados e a análise de sobrevida de Kaplan-Meier foi utilizada para a análise univariada, e uma abordagem progressiva para a regressão logística de Cox foi usada para a análise multivariada. RESULTADOS: A mortalidade por todas as causas foi 44%, 56,5% e 74% para 28-, 90- e 365-dias, respectivamente. A prevalência de IHCA foi de 58%. Desses, 65% grau 1, 17,5% grau 2 e 17,5% grau 3. Na análise multivariada, o uso de inibidores da bomba de prótons, alanina transaminase menor que 40 U/L, hemoglobina acima de 9 g/dL, ausência de IHCA e menores valores dos escores CLIF-SOFA e MELD foram independentemente associados com maior sobrevida para ambos intervalos de 28- e 90-dias. CONCLUSÃO: A presença de IHCA e maiores valores de CLIF-SOFA foram independentemente associados em maior mortalidade para pacientes cirróticos admitidos por PBE no intervalo de 28- e 90-dias.

Desempenho dos escores APACHE II e SOFA em pacientes com injúria renal aguda em uma unidade de terapia intensiva / Performance of APACHE II and SOFA scores in patients with acute kidney injury in an intensive care unit

Objetivo: Validar o desempenho dos escores APACHE II e SOFA para predizer a mortalidade em pacientes com injúria renal aguda em uma unidade de terapia intensiva. Métodos: Estudo observacional e retrospectivo realizado de janeiro de 2018 a setembro de 2020 em um hospital do Rio Grande do Sul. Foram incluídos 256 pacientes. Resultados: Ambos os escores apre- sentaram desempenho adequado para a discriminação da mortalidade em pacientes com injúria renal aguda (área sob a curva para APACHE II de 0,80 e para SOFA de 0,77). Conclusão: A injúria renal aguda é uma condição frequente em ambiente de unidade de terapia intensiva, e os resultados do presente estudo sugerem que ambos os índices são mais precisos quando aplicados em centros únicos e podem ser utilizados rotineiramente para predizer a mortalidade na população

Objective: To validate the performance of the APACHE II and SOFA scores to predict mortality in patients with acute kidney injury in an Intensive Care Unit. Methods: This is an observational and retrospective study conducted from January 2018 to September 2020 at a hospital in Rio Grande do Sul. A total of 256 patients were included. Results: Both scores showed adequate performance for the discrimination of mortality in acute kidney injury patients (area under the curve of 0.80 for APACHE II and 0.77 for SOFA). Conclusion: Acute kidney injury is a frequent condition in intensive care unit settings and the results of the present study suggest that both indices are more accurate when applied in single centers, and can be used routinely to predict mortality in the population

Bar, soft and dri post-hepatic transplantation: what is the best for survival analysis? / Bar, soft e dri pós-transplante hepático: qual é o melhor para análise da sobrevida?

ABSTRACT Background: Liver transplantation is the treatment of choice for patients with terminal liver disease. The Balance of Risk Score (BAR), Survival Outcomes Following Liver Transplantation (SOFT) and Donor Risk Index (DRI) scores are predictive systems for post-transplant survival. Aim: To evaluate the most accurate score and the best cutoff point for each predictor in the brazilian population. Method: Retrospective cross-sectional study of 177 patients. Data on the recipient, donor and transplant were analyzed and the prognostic scores BAR, SOFT and DRI were calculated for each transplant. To determine the BAR and SOFT cutoff points associated with death in three months, ROC curves were adjusted. Results: The best cutoff point for BAR was 9 points with an area under the ROC curve=0.69 and for SOFT it was 12 points with an area under the ROC curve=0.73. The DRI score did not discriminate survival (p = 0.139). Conclusion: The SOFT score proved to be better than BAR for survival analysis post-hepatic transplantation and the DRI was not effective.

RESUMO Racional: Transplante hepático é tratamento de escolha para pacientes com doença hepática terminal. Os escores Balance of Risk Score (BAR), Survival Outcomes Following Liver Transplantation (SOFT) e o Donor Risk Index (DRI) são sistemas preditores de sobrevida após o transplante. Objetivo : Avaliar o escore de maior acurácia e o melhor ponto de corte de cada preditor na população brasileira. Método : Estudo retrospectivo transversal de 177 pacientes. Foram analisados dados sobre o receptor, doador e o transplante e calculados os escores prognósticos BAR, SOFT e DRI para cada transplante. Para a determinar os pontos de corte de BAR e SOFT, associados a óbito em três meses, foram ajustadas curvas ROC. Resultados : O melhor ponto corte para BAR foi 9 pontos com área sob a curva ROC=0,69 e para SOFT foi 12 pontos com área sob a curva ROC=0,73. O escore DRI não discriminou a sobrevida (p=0,139). Conclusão: O escore SOFT mostrou-se melhor do que o BAR para análise de sobrevida pós-transplante hepático, e o DRI não foi efetivo.

Comparison of quick SOFA and SIRS scales at the bedside of patients with Staphylococcus aureus bacteremia / [Comparación de la escala qSOFA para evaluar la falla orgánica secuencial y los criterios SIRS para sepsis a la cabecera de pacientes con bacteriemia por Staphylococcus aureus].

Introduction: One of the primary causes of community-acquired bacteremia also associated with nosocomial infections is Staphylococcus aureus, which is responsible for a high percentage of complications leading to high morbidity and mortality rates. The systemic inflammatory response syndrome (SIRS) criteria have been traditionally used to evaluate the presence of sepsis; however, recent evidence questions its predictive value due to its low sensitivity and specificity. In 2016, new criteria for sepsis were published and a new tool emerged, quick SOFA (qSOFA), for the rapid evaluation of infection in emergency services. Objective: To compare the qSOFA and SRIS tools for the prediction of bacteremia caused by S. aureus. Materials and methods: We conducted an observational study in patients with S. aureus bacteremia to evaluate their phenotypic resistance patterns, some special features (sociodemographic characteristics, clinical and paraclinical values), complications, and mortality. The results of the qSOFA and SIRS scales were analyzed to identify which of them could better predict the presence of S. aureus bacteremia. Results: Twenty-six bacteremic patients were identified. Staphylococcus aureus was the second most frequently isolated bacteria. The results evidenced a mortality rate of 50% (13 cases) and a prevalence of 30% of MRSA. For the clinical scores evaluated, the qSOFA scale was positive in 30.8% of the patients, and the SIRS scale, in 92.3%. Discussion: The mortality rate for the population under study was high and the qSOFA tool had a lower diagnostic yield compared to the classic criteria for SIRS.

Introducción. Staphylococcus aureus es una de las principales causas de bacteriemia, adquirida en la comunidad o asociada con la atención en salud, la cual presenta un gran porcentaje de complicaciones y elevadas tasas de morbilidad y mortalidad. Los criterios SRIS (Systemic Inflammatory Response Syndrome) se han usado tradicionalmente con el fin de establecer la presencia de sepsis; sin embargo, recientemente se ha cuestionado su valor predictivo dada su baja sensibilidad y especificidad. En el 2016, apareció la escala qSOFA (quick Sequential Organ Failure Assessment), como una nueva herramienta para la evaluación rápida de las infecciones en los servicios de urgencias. Objetivo. Comparar las herramientas qSOFA y SRIS para la predicción de la bacteriemia por S. aureus. Materiales y métodos. Se hizo un estudio observacional sobre el comportamiento clínico de pacientes con bacteriemia por S. aureus para evaluar el perfil de resistencia fenotípica, algunas características sociodemográficas, clínicas y de laboratorio, las complicaciones y la mortalidad, así como los resultados de las evaluaciones con la escala qSOFA y los criterios SRIS, para establecer cuál podría predecir mejor la presencia de bacteriemia por S. aureus. Resultados. Se seleccionaron 26 pacientes con bacteriemia, en cuyas muestras S. aureus había sido el segundo germen más frecuentemente aislado. Se encontró una mortalidad del 50 % (13 casos) y una prevalencia del 30 % de S. aureus resistente a meticilina (SARM). Según los puntajes clínicos obtenidos, la escala qSOFA fue positiva en 30,8 % de los pacientes y los criterios SRIS lo fueron en el 92,3 %. Discusión. Se encontró una elevada mortalidad en la población analizada. La escala qSOFA fue menos efectiva para el diagnóstico que los criterios clásicos de reacción inflamatoria sistémica.

Evaluation of the performance of the modified early warning score in a Brazilian public hospital / Evaluación del desempeño de la puntuación de alerta temprana modificada en un hospital público brasileño / Avaliação do desempenho do escore de alerta precoce modificado em hospital público brasileiro

ABSTRACT Objective: To evaluate the performance of the modified early warning score (Mews) in a nursing ward for patients in clinical deterioration. Method: This is an analytical, quantitative and predictive study. Mews' parameters (systolic blood pressure, heart rate, respiratory rate, temperature and level of consciousness) were evaluated every six hours. The following events were reported: death, cardiopulmonary arrest and transfer to intensive care. The evaluations were performed in a hospital of reference in the state of São Paulo, Brazil. Results: A total of 300 patients were included (57 ± 18 years old, males: 65%). There number of combined events was observed to be greater the higher the score's value (00%; 00%; 01; 09%; 19%; 28%; 89%, respectively, for Mews 0; 1; 2; 3; 4; 5 and 6; p < 0.0001). Mews ≥ 4 was the most appropriate cut-off point for prediction of these events (sensitivity: 87%, specificity: 85% and accuracy: 0.86). Conclusion: Mews properly measured the occurrence of severe events in hospitalized patients of a Brazilian public hospital's nursing ward. Mews ≥ 4 seems to be the most appropriate cut-off point for prediction of these events.

RESUMEN Objetivo: Evaluar el desempeño de la puntuación de alerta temprana modificada (Mews) en una enfermería de pacientes con deterioro clínico.
