Performance of severity indices for admission and mortality of trauma patients in the intensive care unit: a retrospective cohort study.

BACKGROUND: Little is known about the performance of severity indices for indicating intensive care and predicting mortality in the Intensive Care Unit (ICU) of trauma patients. This study aimed to compare the performance of severity indices to predict trauma patients' ICU admission and mortality. METHODS: A retrospective cohort study which analyzed the electronic medical records of trauma patients aged ≥ 18 years, treated at a hospital in Brazil, between 2014 and 2017. Physiological [Revised Trauma Score (RTS), New Trauma Score (NTS) and modified Rapid Emergency Medicine Score (mREMS)], anatomical [Injury Severity Score (ISS) and New Injury Severity Score (NISS)] and mixed indices [Trauma and Injury Severity Score (TRISS), New Trauma and Injury Severity Score (NTRISS), Base-deficit Injury Severity Score (BISS) and Base-deficit and New Injury Severity Score (BNISS)] were compared in analyzing the outcomes (ICU admission and mortality) using the Area Under the Receiver Operating Characteristics Curves (AUC-ROC). RESULTS: From the 747 trauma patients analyzed (52.5% female; mean age 51.5 years; 36.1% falls), 106 (14.2%) were admitted to the ICU and 6 (0.8%) died in the unit. The ISS (AUC 0.919) and NISS (AUC 0.916) had better predictive capacity for ICU admission of trauma patients. The NISS (AUC 0.949), TRISS (AUC 0.909), NTRISS (AUC 0.967), BISS (AUC 0.902) and BNISS (AUC 0.976) showed excellent performance in predicting ICU mortality. CONCLUSIONS: Anatomical indices showed excellent predictive ability for admission of trauma patients to the ICU. The NISS and the mixed indices had the best performances regarding mortality in the ICU.

Patients Air Medical Transport During the COVID-19 Pandemic: A Retrospective Cohort Study.

INTRODUCTION: Air medical transport during the coronavirus disease 2019 pandemic was essential for transferring critically ill patients. This study aimed to comparatively analyze air-transported patients with and without coronavirus disease 2019 according to their clinical condition and complications that occurred during the flight. METHODS: This was a retrospective cohort study that analyzed the digital records of adult patients transported by fixed-wing aircraft from the interior of the state of Amazonas to the state capital Manaus, Brazil, from June 2019 to May 2021. Pearson's chi-squared, Fisher exact, and Wilcoxon-Mann-Whitney tests were applied (significance level of P < .05). RESULTS: The sample consisted of 741 patients (60.59% men, median age 54 years). The incidence of complications during the flight was 7.28%, with emphasis on dyspnea, psychomotor agitation, and pain. There was a significant difference between patients with (n = 466) and without coronavirus disease 2019 (n = 275) regarding the variables age (P < .001), comorbidities (P < .001), body mass index (P < .001), impact (P < .001) and priority (P = .002) of the transfer, physiological severity (P < .001), use of vasoactive drugs when boarding the aircraft (P = .033), and occurrence of respiratory complications during air medical transport (P = .003). DISCUSSION: Patients with coronavirus disease 2019 were older, had more comorbidities and were severely ill, and had higher body mass index, frequency of vasoactive drug use, and respiratory complications. Although there are minimal differences among these patients, the role that interhospital transfer plays in reducing burden on local, less well-equipped hospitals is a primary role of medical transport, particularly during pandemics.

Features of the triggering of the yellow code and factors associated with the occurrence of adverse events.

OBJECTIVE: to analyze the characteristics of the activation of the yellow code in wards and identify the factors associated with adverse events after the Rapid Response Team. METHODS: a cross-sectional study with retrospective analysis of medical records of adults admitted to medical or surgical clinic wards of the University Hospital of São Paulo. RESULTS: among the 91 patients, the most frequent signs of triggers (n=107) were peripheral oxygen saturation of less than 90% (40.2%) and hypotension (30.8%). Regarding the associated factors the research identified each minute of attendance of the Rapid Response Team in the wards increased by 1.2% odds of adverse events (twenty-four unplanned admission in the ICU and one cardiac arrest) in the sample (p=0.014). CONCLUSIONS: decreased oxygen saturation and hypotension were the main reasons for the triggering, and the length of care was associated with the frequency of adverse events.

COVID-19 infection in nursing staff: A cohort study.

AIM: This study aims to identify the working conditions of Brazilian nursing professionals and the risk factors for these professionals to become infected by coronavirus disease. BACKGROUND: Understanding the factors that affected nursing professionals during the pandemic can support better nursing management. DESIGN: This is a quantitative, cross-sectional survey study. METHODS: Data collection was carried out between February and March 2022 in Brazil. All nursing professionals registered in the national database received by e-mail the study instrument with the data collection variables: professionals' sociodemographic and comorbid, professional and institutional characteristics, and professionals' health conditions and disease-related aspects for COVID-19. RESULTS: Four thousand eight hundred sixty-two nursing professionals reported a lack of personal protective equipment for patient care, and 4424 were infected by coronavirus disease. The risk factors to become infected were having cardiovascular disease, being under 60 years of age, living in the northern region, using public transportation, working in a hospital, an emergency department or reference institution for COVID-19, living with an infected person and lack of respirators or waterproof aprons. CONCLUSION: Multiple risk factors for infection with SARS-CoV-2 were demonstrated for the nursing professionals during the pandemic, highlighting current and future pandemics factors that are modifiable in a worthwhile time frame to minimize nurses' infection risks, such as inadequate working conditions associated with lack of essential personal protective equipment.

Effect of the national early warning score on monitoring the vital signs of patients in the emergency room.

OBJECTIVE: To verify the effect of using the National Early Warning Score (NEWS) system on the compliance of the vital signs monitoring interval with those recommended for patients in the emergency room. METHODS: This is a quasi-experimental, before-and-after study, performed in an emergency room with 280 adult patients selected by convenience. The effect of NEWS on the compliance of the vital signs monitoring interval with those recommended by the system was analyzed by linear regression. RESULTS: In the Pre-NEWS phase, 143 patients were analyzed (mean age ± standard deviation: 54.4 ± 20.5; male: 56.6%) and, in the Post-NEWS phase, 137 patients (mean age ± standard deviation: 55.5 ± 20.8; male: 50.4%). There was compliance of the vital signs monitoring interval with what is recommended by NEWS in 92.6% of vital signs records after adopting this instrument. This compliance was 9% (p < 0.001) higher in the Post-NEWS phase. CONCLUSION: The use of the NEWS system increased the compliance of the vital signs monitoring intervals with the ones recommended, but this compliance decreased when the NEWS score pointed to a shorter interval in the monitoring of vital signs.

Effectiveness of cardiopulmonary resuscitation training in the teaching of family members of cardiac patients.

OBJECTIVE: To evaluate the effectiveness of a cardiopulmonary resuscitation training in the skill acquisition of family members of heart disease patients. METHOD: A quasi-experimental study, conducted in a hospital in São Paulo, Brazil. The study participants were one or more relatives of patients with heart disease that were hospitalized at the institution. In the first phase, the participant's skills and theoretical knowledge on cardiopulmonary resuscitation were evaluated before and immediately after the training. The second phase took place one month after the training, in which the same evaluations were applied. The McNemar's and Stuart-Maxwell tests were adopted (5% significance level). RESULTS: The theoretical knowledge of family members before and after training increased and a great retention of this knowledge after 30 days of training was observed. Immediately after training, the family members showed significant improvement of skills in the 15 analyzed actions and, after one month of training, they maintained most of the acquired practices on cardiopulmonary resuscitation, except for chest compressions frequency and the time between turning on the defibrillator and delivering the shock. CONCLUSION: Cardiopulmonary resuscitation training was effective in the acquisition of theoretical and practical knowledge of the family members.

Factors associated with infection and hospitalization due to COVID-19 in Nursing professionals: a cross-sectional study. / Fatores associados à contaminação e internação hospitalar por COVID-19 em profissionais de enfermagem: estudo transversal.

OBJECTIVE: to identify factors associated with infection and hospitalization due to COVID-19 in nursing professionals. METHOD: a cross-sectional study carried out with 415 nursing professionals in a hospital specialized in cardiology. The sociodemographic variables, comorbidities, working conditions and issues related to illness due to COVID-19 were evaluated. Chi-Square, Fisher's, Wilcoxon, Mann-Whitney and Brunner Munzel tests were used in data analysis, as well as Odds Ratio for hospitalization, in addition to binary logistic regression. RESULTS: the rate of nursing professionals affected by COVID-19 was 44.3% and the factors associated with infection were the number of people living in the same household infected by COVID-19 (OR 36.18; p<0.001) and use of public transportation (OR 2.70; p=0.044). Having severe symptoms (OR 29.75), belonging to the risk group (OR 3.00), having tachypnea (OR 6.48), shortness of breath (OR 5.83), tiredness (OR 4.64), fever (OR 4.41) and/or myalgia (OR 3.00) increased the chances of hospitalization in professionals with COVID-19. CONCLUSION: living in the same household as other people with the disease and using public transportation increased the risk of infection by the new coronavirus. The factors associated with the hospitalization of contaminated professionals were presence of risk factors for the disease, severity and type of the symptoms presented.

Performance of the Modified Rapid Emergency Medicine Score in Patients With and Without Traumatic Brain Injury.

ABSTRACT: BACKGROUND: The modified Rapid Emergency Medicine Score (mREMS) is a recently published index to estimate the severity of trauma patients; however, little is known about its performance in patients with different types of trauma. This study verified the predictive capacity of mREMS in-hospital mortality in patients of blunt and penetrating trauma with and without traumatic brain injury (TBI) and the performance of this index compared with the Rapid Emergency Medicine Score, Injury Severity Score, New Injury Severity Score, and Trauma and Injury Severity Score. METHODS: This is a retrospective, correlational study that analyzed trauma patients 18 years or older, who attended at a hospital in Rio de Janeiro, Brazil. The receiver operating characteristic (ROC) curve was applied in the analyses. RESULTS: The sample consisted of 987 patients, 359 (36.4%) with TBI (225 blunt and 134 penetrating trauma). Regarding mREMS, the area under the ROC curve for TBI patients for in-hospital mortality was 0.506 (95% confidence interval [CI], 0.404-0.609) for penetrating injuries and 0.486 (95% CI, 0.402-0.571) for blunt injuries; the values in patients without TBI were 0.629 (95% CI, 0.554-0.703) and 0.618 (95% CI, 0.552-0.684), respectively. In relation to the other indices the mREMS presented the lowest area under the curve/ROC for penetrating and blunt TBI, and the Rapid Emergency Medicine Score for extracranial injuries. CONCLUSION: The mREMS showed no prognostic capacity for patients with TBI, and it presented the worst performance in relation to the Injury Severity Score, New Injury Severity Score, and Trauma and Injury Severity Score to discriminate cases of in-hospital mortality when considering trauma patients with and without TBI.

Rapid triage performed by nurses: Signs and symptoms associated with identifying critically ill patients in the emergency department.

AIM: Aim of this study is to identify signs and symptoms associated with identifying critically ill patients by rapid triage assessment performed by nurses in an emergency department. BACKGROUND: In some emergency services, the immediate assessment of critically ill patients occurs before opening the hospital formal registration and it is based on the nurse's experience. Studies on the topic are essential to improve this process. DESIGN: This is a cross-sectional, quantitative study. METHODS: This study was conducted in a Brazilian emergency department in 2017. Adult patients who presented potentially life-threatening symptoms underwent rapid triage to determine the medical urgency. Those identified as being critically ill were classified as high priority and streamed to the emergency room. RESULTS: A total of 154 (84.6%) patients were classified as high priority from the total of 182 evaluations. Altered state of consciousness (35.2%) and altered skin perfusion (25.3%) were frequently identified. Signs and symptoms associated with identifying critically ill patients by rapid triage were alterations in ventilation (OR 6.09; p = 0.028), neurological dysfunction (OR 44.96; p < 0.001) and pain (OR 5.80; p = 0.004). CONCLUSION: Nurses should value neurological and ventilation alterations and pain in patients during rapid triage, since these signs and symptoms are associated with high care priority.

[A riverine emergency health service: characteristics and factors related to patients' clinical evolution]. / Serviço fluvial de emergência: características e fatores relacionados à evolução clínica dos atendidos.

The study aimed to describe the profile of patients and the care provided by the Mobile Riverine Emergency Medical Service (SAMU) in river-dwelling communities of the Amazon and to identify factors related to patients' evolution during care by this service. This descriptive study was conducted in two stages: in the first, the data were obtained on care for individuals in the service from 2009 to 2015; in the second, the data collection was prospective during the first semester of 2016, and patients' evolution was assessed with the Rapid Emergency Medicine Score. In all the periods analyzed, some 90% of the care included medical evacuation, varying over the years as to the type of boat used most frequently in transporting the patients. The most frequent reasons for care were signs and symptoms of unknown etiology and external causes. Of the patients transported by the service in the first semester of 2016, 68.5% maintained their clinical status, 18% worsened, and 13.5% improved during care. For patients seen during this period, the mean response and total riverine care times were 84 and 172 minutes, respectively. There was an association between evolution and incidents involving venomous snakes, acute pain, age, initial severity, and destination of the patient. Causes of care were related to worsening clinical status during care, and patients who worsened were younger and in less serious condition and were more frequently evacuated to hospitals. The profile of patients and care in the riverine SAMU pointed to the need for a revision of this service's objectives and structuring.

O objetivo deste estudo foi descrever o perfil dos usuários e a assistência prestada pelo Serviço de Atendimento Móvel de Urgência (SAMU) fluvial em comunidades ribeirinhas amazônicas e identificar fatores relacionados à evolução dos pacientes durante o atendimento desse serviço. Trata-se de um estudo descritivo realizado em duas etapas: na primeira, os dados dos atendimentos dos indivíduos realizados pelo serviço de 2009 a 2015 foram a fonte de informações; na segunda, a coleta de dados foi prospectiva durante o primeiro semestre de 2016 e a evolução dos pacientes foi avaliada pelo Rapid Emergency Medicine Score. Em todos os períodos analisados, cerca de 90% dos atendimentos incluíram remoção, variando ao longo dos anos o tipo de embarcação mais utilizada no transporte. As causas dos atendimentos foram, predominantemente, sintomas e sinais de etiologia desconhecida ou causas externas. Dos pacientes transportados pelo serviço no primeiro semestre de 2016, 68,5% mantiveram o quadro clínico, 18% pioraram e 13,5% melhoraram durante o atendimento. Para os atendidos nesse período, os tempos médios, resposta e total de atendimento fluvial foram 84 e 172 minutos, respectivamente. Houve associação entre evolução e ocorrências com serpentes venenosas, presença de dor aguda, idade, gravidade inicial e destino do usuário. Causas de atendimento tiveram relação com o agravamento durante a assistência e os que pioraram eram mais jovens, de menor gravidade e foram, com maior frequência, encaminhados para hospitais. O perfil dos usuários e dos atendimentos do SAMU fluvial apontou para necessidade de revisão dos propósitos e de estruturação desse serviço.

El objetivo de este estudio fue describir el perfil de los usuarios y la asistencia prestada por el Servicio de Atención Móvil de Urgencia (SAMU) fluvial en comunidades ribereñas amazónicas, así como identificar factores relacionados con la evolución de los pacientes durante la atención de ese servicio. Se trata de un estudio descriptivo realizado en dos etapas: en la primera, la fuente de información fueron los datos de las consultas de los individuos, realizadas por el servicio de 2009 a 2015; en la segunda, la recogida de datos fue prospectiva durante el primer semestre de 2016 y la evolución de los pacientes fue evaluada por el Rapid Emergency Medicine Score. En todos los períodos analizados, cerca de un 90% de las consultas incluyeron desplazamiento, variando a lo largo de los años el tipo de embarcación más utilizada en el transporte. Las causas de la atención fueron, predominantemente, síntomas y señales de etiología desconocida o causas externas. De los pacientes transportados por el servicio en el primer semestre de 2016, un 68,5% mantuvieron el cuadro clínico, 18% empeoraron y 13,5% mejoraron durante la atención. Para los atendidos en ese período, los tiempos medios, respuesta y total de atención fluvial, fueron 84 y 172 minutos, respectivamente. Hubo asociación entre evolución y ocurrencias con serpientes venenosas, presencia de dolor agudo, edad, gravedad inicial y destino del usuario. Las causas de atención estuvieron relacionadas con el agravamiento durante la asistencia, y quienes empeoraron eran más jóvenes, de menor gravedad y fueron, con mayor frecuencia, dirigidos a hospitales. El perfil de los usuarios y de la atención del SAMU fluvial apuntó la necesidad de una revisión de los propósitos, así como de la estructuración de ese servicio.

Severity indexes of blunt trauma victims in intensive therapy: prediction capacity for mortality. / Índices de gravidade em vítimas de trauma contuso na terapia intensiva: capacidade preditiva de mortalidade.

OBJECTIVE: To identify the predictive capacity for mortality of the indexes Revised Trauma Score, Rapid Emergency Medicine Score, modified Rapid Emergency Medicine Score, and Simplified Acute Physiology Score III in blunt trauma victims hospitalized in an intensive care unit and compare their performance. METHOD: Retrospective cohort of patients with blunt trauma in an intensive care unit from medical records. Receiver Operating Characteristic and a 95% confidence interval of the area under the curve were analyzed to compare results. RESULTS: Out of 165 analyzed patients, 66.7% have received surgical treatment. The mortality in the intensive care unit and in the hospital was 17.6% and 20.6%, respectively. For the mortality in the intensive care unit, the area under the curve varied from 0.672 to 0.738; however, better results have been observed in surgical patients (0.747 to 0.811). Similar results have been observed for in-hospital mortality. In all analyses, the areas under the curve of the indexes presented no significant difference. CONCLUSION: The accuracy of the severity indexes was moderate, with an improved performance when applied to surgical patients. The four indexes presented a similar prediction for the analyzed outcomes.

Effect of post-storage filters vs. pre-storage filters for leukoreduction of blood components on clinical outcomes: a systematic review protocol.

OBJECTIVE: This review will synthesize the best available evidence on the effectiveness of leukocyte reduction by comparing post-storage and pre-storage filters. The review will consider the following clinical outcomes: transfusion reactions, bacterial infection, length of stay, and mortality. INTRODUCTION: Transfusion is a relevant therapy, but it is not risk-free. Leukocyte reduction can be performed either by apheresis or by pre- or post-storage filters in order to reduce the risk of transfusion reactions, transmission of some diseases, alloimmunization, and platelet refractoriness. It can also reduce the length of hospital stay and the use of antibiotics. INCLUSION CRITERIA: Studies comparing the transfusion of leukocyte reduction through post-storage filters with pre-storage filters in patients of any age who received a transfusion and the clinical outcomes resulting from the transfusion will be considered for inclusion. Studies in Portuguese, English, and Spanish will be considered, with no publication time limit. METHODS: The research sources will include MEDLINE (PubMed), CINAHL (EBSCO), PsycINFO, Scopus, The Cochrane Library, Web of Science Core Collection, Embase, LILACS, and gray literature sources. The selection of titles and abstracts will be carried out by two independent reviewers, and the critical evaluation of the studies will be based on JBI tools. The data of interest for the review question will be extracted using JBI SUMARI. A narrative synthesis will be performed as will a meta-analysis and risk assessment of publication bias, if possible.
