RESUMO
Abstract Introduction Plasma transfusion is a common therapeutic strategy used to lower international normalized ratio (INR) values in the non-emergent setting. However, due to lack of evidence of its efficacy, standardized guidelines for this practice have not been well established. Methods This retrospective observational cohort study analyzed 276 inpatient encounters that involved plasma transfusions focusing on change in INR values from pre- to post-transfusion, with respect to the following predictor variables: vitamin K co-administration, number of plasma units transfused, order indication and body mass index (BMI). Results The overall average change in the INR was 1.35. Patients who received vitamin K showed an average change of 2.51, while patients that did not receive vitamin K demonstrated an average change of 0.70. Increased numbers of plasma units transfused showed benefit up to three-unit orders. Greater decreases in the INR were observed for patients requiring plasma for anticoagulation reversal or active bleeding. There was no significant difference in the change in INR based on the BMI. By multivariate and regression analyses, the stepwise addition of each successive predictor variable demonstrated an increase in the shared variance in the outcome of the post-transfusion INR: the pre-transfusion INR and vitamin K co-administration alone was not significant (p= 0.45); the additional number of plasma units transfused was significant (R² = 0.13, p < 0.001), and; the subsequent additional plasma order indications (R² = 0.19, p < 0.001) and BMI (R² = 0.18, p < 0.001) were increasingly significant. Conclusion Taking into consideration the combination of multiple predictive factors may aid in a more efficient use of plasma products.

RESUMO
Background: We evaluated in-hospital mortality and outcomes incidence after hospital discharge due to COVID-19 in a Brazilian multicenter cohort. Methods: This prospective multicenter study (RECOVER-SUS, NCT04807699) included COVID-19 patients hospitalized in public tertiary hospitals in Brazil from June 2020 to March 2021. Clinical assessment and blood samples were performed at hospital admission, with post-hospital discharge remote visits. Hospitalized participants were followed-up until March 31, 2021. The outcomes were in-hospital mortality and incidence of rehospitalization or death after hospital discharge. Kaplan-Meier curves and Cox proportional-hazard models were performed. Findings: 1589 participants [54.5% male, age=62 (IQR 50-70) years; BMI=28.4 (IQR,24.9-32.9) Kg/m² and 51.9% with diabetes] were included. A total of 429 individuals [27.0% (95%CI,24.8-29.2)] died during hospitalization (median time 14 (IQR,9-24) days). Older age [vs<40 years; age=60-69 years-aHR=1.89 (95%CI,1.08-3.32); age=70-79 years-aHR=2.52 (95%CI,1.42-4.45); age≥80-aHR=2.90 (95%CI 1.54-5.47)]; noninvasive or mechanical ventilation at admission [vs facial-mask or none; aHR=1.69 (95%CI 1.30-2.19)]; SAPS-III score≥57 [vs<57; aHR=1.47 (95%CI 1.13-1.92)] and SOFA score≥10 [vs <10; aHR=1.51 (95%CI 1.08-2.10)] were independently associated with in-hospital mortality. A total of 65 individuals [6.7% (95%CI 5.3-8.4)] had a rehospitalization or death [rate=323 (95%CI 250-417) per 1000 person-years] in a median time of 52 (range 1-280) days post-hospital discharge. Age ≥ 60 years [vs <60, aHR=2.13 (95%CI 1.15-3.94)] and SAPS-III ≥57 at admission [vs <57, aHR=2.37 (95%CI 1.22-4.59)] were independently associated with rehospitalization or death after hospital discharge. Interpretation: High in-hospital mortality rates due to COVID-19 were observed and elderly people remained at high risk of rehospitalization and death after hospital discharge.

RESUMO
El índice internacional normalizado (INR, por sus siglas en inglés), es un tipo de cálculo matemático que se basa en las pruebas de tiempo de protrombina. La seguridad y eficacia de la terapia dependen del efecto anticoagulante que reciban dentro del margen terapéutico fijado por el médico en base al estudio de sus tiempos de coagulación, específicamente expresado como el intervalo de INR. Establecer los rangos de referencia del INR aplicado en resultados obtenidos en pacientes del sexo masculino y femenino en edades entre los 18 hasta 60 años de edad en el Hospital San Juan de Dios de Cuenca, durante los meses de enero a junio del año 2021. Los datos fueron recopilados de 699 pacientes que acudieron a consulta externa del Hospital San Juan de Dios de Cuenca del área de hematología, que incluyen valores de tiempo de tromboplastina y su referente INR en base al ISI establecido en el reactivo emitido por el fabricante. Se establecieron los valores normales de INR los cuales varían en referencia al sexo del paciente. Para el sexo masculino valores con límite inferior 0,82 y límite superior 1,16; para el sexo femenino con límite inferior de 0,51 y el límite superior de 1,51. Los valores de INR tienen variaciones de acuerdo al sexo siendo los valores de hombres mas altos en relación al de las mujeres en el rango inferiores, Evidentemente los factores influyentes van en relación del sexo, edad, dieta y sobretodo la genética del paciente.
The International Normalized Ratio (INR) is a type of mathematical calculation based on prothrombin time testing. The safety and efficacy of therapy depend on the anticoagulant effect they receive within the therapeutic range set by the physician based on the study of their clotting times, specifically expressed as the INR range. To establish the reference ranges of the INR applied in results obtained in male and female patients between 18 and 60 years of age at the San Juan de Dios Hospital in Cuenca, during the months of January to June 2021. The data were collected from 699 patients who attended the outpatient clinic of the Hospital San Juan de Dios de Cuenca in the hematology area, including thromboplastin time values and their INR referent based on the ISI established in the reagent issued by the manufacturer. Normal INR values were established, which vary according to the patient's sex. For the male sex values with a lower limit of 0.82 and an upper limit of 1.16; for the female sex with a lower limit of 0.51 and an upper limit of 1.51. The INR values vary according to sex, with the values for men being higher in relation to those for women in the lower range. Evidently, the influencing factors are related to sex, age, diet and above all the patient's genetics.

Introducción: Solo el 60 por ciento de los pacientes en tratamiento con antagonistas de la vitamina K (AVK) están controlados. Objetivos: A nalizar una cohorte de pacientes anticoagulados para valorar su grado de control y su evolución a los 2 años, tras una intervención formativa breve. Métodos: Estudio longitudinal, observacional, retrospectivo de 157 anticoagulados con AVK. Se recogieron datos sociodemográficos, comorbilidades, motivo de prescripción del AVK y grado de control basal y tras 2 años de seguimiento. Utilizamos 2 métodos de valoración diferentes: Rosendaal y método directo (porcentaje de INR-Razón Normalizada Internacional- en rango). Asimismo, establecimos correlaciones temporales intramétodo. Resultados: El grado de control pasó del 47,3 por ciento al 53,5 por ciento a los 2 años, según Rosendaal (p= 0,52), y del 39,5 por ciento al 53,5 por ciento según el método directo (p< 0,05). El tiempo en rango terapéutico fue del 63,1 ±19,9 por ciento al inicio y 65 ±19,2 por ciento al final del seguimiento. La correlación entre los 2 controles fue positiva para ambos métodos (Rosendaal: 0,23; método directo: 0,33). El análisis multivariante fue significativo para el sexo masculino y para un objetivo diferente de 2,5-3,5 (odds ratio: 2,22 y 2,73, respectivamente). Conclusiones: El control del INR mejoró a los 2 años de seguimiento tras la actividad formativa. La evolución del grado de control de cada paciente es parcialmente predecible. El peor control se asoció al sexo femenino y al objetivo de INR de 2,5-3,5. El control mejora 2,22 veces en los varones y 2,73 veces en quienes no tienen un INR objetivo de 2,5-3,5(AU)
Introduction: Only 60 percent of patients on treatment with vitamin K antagonists (AVK) are controlled. Objectives: We proposed to analyze a cohort of anticoagulated patients to assess their degree of control and their evolution at 2 years, after a brief training intervention. Methods: Longitudinal, observational, retrospective study of 157 anticoagulated with AVK. Sociodemographic data, comorbidities, reason for VKA prescription and degree of baseline control were collected and after 2 years of follow-up. We use 2 different valuation methods: Rosendaal and direct method (INR percentage -International Normalized Ratio- in range). Likewise, we established intra-method temporal correlations. Results: The degree of control went from 47.3 percent to 53.5 percent at 2 years, according to Rosendaal (p = 0.52), and from 39.5 percent to 53.5 percent according to the direct method (p<0.05). The time in the therapeutic range was 63.1±19.9 percent at the start and 65±19.2 percent at the end of the follow-up. The correlation between the 2 controls was positive for both methods (Rosendaal: 0.23; direct method:0.33). The multivariate analysis was significant for males and for a target other than 2.5-3.5(odds ratio: 2.22 and 2.73, respectively). Conclusions: INR control improved after 2 years of follow-up after training activity. The evolution of the degree of control of each patient is partially predictable. The worst control was associated with female sex and the INR goal of 2.5-3.5. Control improves 2.22 times in males and 2.73 times in those without a target INR of 2.5-3.5(AU)

RESUMO
Treating an anticoagulated patient with vitamin K antagonists (VKA) remains a challenge, especially in areas where dicoumarins are still the first drug of choice due to the cost of other oral anticoagulants. Anticoagulation clinics have proven to be the most efficient and safe way to avoid thrombotic and hemorrhagic complications and to keep patients in optimal treatment range. However, they require adequate infrastructure and trained personnel to work properly. In this Argentine consensus we propose a series of guidelines for the effective management of the anticoagulation clinics. The goal is to achieve the excellence in both the clinical healthcare and the hemostasis laboratory for the anticoagulated patient. The criteria developed in the document were agreed upon by a large group of expert specialists in hematology and biochemistry from all over the country. The criteria presented here must always be considered when indicating VKA although they had to be adapted to the unequal reality of each center. Taking these premises into consideration will allow us to optimize the management of the anticoagulated patient with VKA and thus minimize thrombotic and hemorrhagic intercurrences, in order to honor our promise not to harm the patient.

Sepse é definida como uma resposta inflamatória sistêmica frente a um microrganismo, sendo uma das principais causas de morte em pacientes internados em unidades de terapia intensiva (UTI). Na sepse, a cascata de coagulação é ativada, contribuindo na formação de tromboembolismo venoso localizado e coagulação intravascular disseminada, uma das responsáveis pela síndrome da disfunção orgânica múltipla; além disso, o consumo de plaquetas e de proteínas de coagulação pode resultar em hemorragias graves. Pacientes com sepse internados em UTI têm como principais prestadores de assistência a equipe de enfermagem que pode ter suas atividades organizadas pela Sistematização da Assistência de Enfermagem (SAE). A SAE possibilita perspectivas em relação ao cuidado, guia e normatiza mais precisamente a assistência de enfermagem direcionando a resolução dos problemas dos pacientes, pois mobiliza competências profissionais específicas no cuidado, resultando na qualidade da assistência. Esse estudo objetivou avaliar a relação de dois componentes do sistema hemostático (contagem de plaquetas e International Normalized Ratio - INR) com a gravidade clínica e com o desfecho em pacientes diagnosticados com sepse internados na UTI. Trata-se de um estudo quantitativo, exploratório e correlacional no qual os dados foram coletados de maneira pregressa. O estudo desenvolveu-se num hospital público de cuidados de alta complexidade em nível ambulatorial e hospitalar, por meio da análise de prontuários de pacientes diagnosticados com sepse internados na UTI no período de janeiro a dezembro de 2017. As variáveis relacionadas às características sócio- demográficas, clínicas e o tempo de assistência de enfermagem foram coletadas do prontuário eletrônico dos pacientes utilizando-se formulário específico. Foram incluídos 176 prontuários. Não foram observadas diferenças estatisticamente significantes em relação ao sexo, idade ou raça dos pacientes, contudo, os resultados mostram que pacientes com desfecho óbito apresentaram piores valores dos parâmetros clínicos e laboratoriais, demandaram mais cuidados de enfermagem e apresentaram contagem de plaquetas menor e INR maior do que os pacientes que tiveram alta; além disso, observou-se que a contagem de plaquetas <100.000 mm3 e o INR>1,5 estão associados à maior frequência do desfecho óbito. Foi analisada a capacidade da contagem de plaquetas e do INR para predizerem o óbito por meio de uma curva ROC que indicaram a contagem de plaquetas como um preditor não adequado e o INR um preditor fraco para o desfecho óbito. Assim, este estudo mostrou que os pacientes diagnosticados com sepse que foram a óbito apresentaram maior comprometimento orgânico e demandaram mais cuidados de enfermagem do que aqueles que tiveram como desfecho a alta hospitalar, além disso, a contagem de plaquetas e o INR indicam um comprometimento do sistema hemostático, sinalizando um quadro fibrinolítico. Tanto a contagem de plaquetas quanto o INR foram associados ao óbito, no entanto, não se mostraram bons preditores para tal. O dimensionamento do trabalho de enfermagem utilizando o NAS, a avaliação dos exames laboratoriais e da gravidade através dos SAPS 3, realizados pelo enfermeiro com conhecimento específico, facilita a elaboração e evolução da SAE. Quanto mais dados, mais acurada a análise, levando a modificações do planejamento da assistência de enfermagem
Sepsis is defined as a systemic inflammatory response to a microorganism, being a major cause of death in intensive care unit (ICU) patients. In sepsis, the coagulation cascade is activated, contributing to the formation of localized venous thromboembolism and disseminated intravascular coagulation, one of the causes of multiple organ dysfunction syndrome. In addition, the consumption of platelets and coagulation proteins may result in serious bleeding. Patients with sepsis admitted to the ICU have, as their main care providers, the nursing staff that may have their activities organized by the Nursing Care Systematization (NCS). NCS provides perspectives regarding care, guides and regulates more precisely nursing care, directing the resolution of patients' problems, as it mobilizes specific professional skills in care, resulting in the quality of care. This study aimed to evaluate the relationship of two components of the hemostatic system (platelet count and International Normalized Ratio - INR) with clinical severity and outcome in patients diagnosed with ICU sepsis. This is a quantitative, exploratory and correlational study in which data were previously collected. The study was developed in a public hospital of high complexity care at the outpatient and inpatient level through the analysis of medical records of patients diagnosed with sepsis admitted to the ICU from January to December 2017. The variables related to socio-demographic, clinical characteristics and length of nursing care were collected from the patients' electronic medical records using a specific form. We included 176 medical records. No statistically significant differences were observed regarding gender, age or race of patients; however, the results show that patients with death outcome had worse clinical and laboratory parameter values, required more nursing care and had lower platelet count and higher INR than patients who were discharged; in addition, platelet counts <100,000 mm3 and INR> 1.5 were associated with a higher frequency of death outcome. We analyzed the ability of platelet count and INR to predict death by means of a ROC curve that indicated platelet count as an inadequate predictor and INR as a weak predictor of death outcome. Thus, this study showed that patients diagnosed with sepsis who died had greater organic impairment and demanded more nursing care than those who were discharged from the hospital. In addition, the platelet counts and INR indicate a compromised hemostatic system, signaling a fibrinolytic picture. Both platelet count and INR were associated with death; however, they were not good predictors for it. The dimensioning of nursing work using the NAS, the evaluation of laboratory tests and severity on SAPS 3, performed by a nurse with specific knowledge, facilitates the elaboration and evolution of the NCS. The more data, the more accurate the analysis, leading to changes in nursing care planning
