Uso de isoflurano como tratamiento del estado epiléptico superrefractario / Use of isoflurane as treatment for super-refractory status epilepticus

Introducción: El estado epiléptico superrefractario (EESR) es una entidad neurológica con una importante morbimortalidad, en la que se dispone de pocas opciones terapéuticas. La sedación inhalatoria con isoflurano es un tratamiento de uso compasivo actualmente en las unidades de cuidados intensivos españolas. Existe poca documentación sobre su utilidad en el tratamiento del estado epiléptico refractario y superrefractario, pero parece ser una alternativa terapéutica útil y segura para esta patología. Casos clínicos: Este artículo es una revisión de tres casos de EESR tratados con isoflurano. Se evaluó el control de las crisis epilépticas por isoflurano mediante monitorización electroencefalográfica. Otras variables evaluadas han sido el tiempo transcurrido hasta el control de las crisis, la supervivencia, el resultado funcional y la aparición de complicaciones secundarias al isoflurano. En los tres casos revisados, el isoflurano se mostró efectivo para el control de las crisis epilépticas en pacientes afectados por EESR. El control de las crisis epilépticas se logró rápidamente, y se pudo titular fácil y rápidamente la mínima dosis que obtenía el patrón burst-suppression. A pesar del control de la epilepsia, se objetivó una elevada mortalidad (66,66%). Esto se explica tanto por la mortalidad del EESR como por las patologías subyacentes de los pacientes fallecidos. El uso de isoflurano no presentó complicaciones. Conclusión: Con los resultados obtenidos, es factible pensar que el uso de isoflurano no se relaciona con las lesiones en el sistema nervioso central descritas en otros artículos, y se puede considerar que este tratamiento es efectivo y seguro para el control del EESR.(AU)

Introduction: Super-refractory status epilepticus (SRSE) is a neurological condition with an important morbidity and mortality rate, for which few therapeutic options are available. Inhalation sedation with isoflurane is currently a compassionate-use treatment in Spanish intensive care units. Little has been written about its usefulness in the treatment of refractory and super-refractory status epilepticus, but it appears to be a useful and safe therapeutic alternative for this condition. Case reports: This article reviews three cases of SRSE treated with isoflurane. The capacity of isoflurane to control seizures was assessed by electroencephalographic monitoring. Other variables assessed were time to seizure control, survival, functional outcome and occurrence of complications secondary to isoflurane. In the three cases reviewed, isoflurane proved to be effective for seizure control in patients affected by SRSE. Seizure control was accomplished quickly and the minimum dose required to obtain a burst-suppression pattern was titrated easily and rapidly. Despite controlling epilepsy, high mortality was observed (66.66%). This is explained by both the mortality of SRSE and the underlying pathologies of the patients who died. The use of isoflurane did not give rise to any complications. Conclusion: With the results obtained, it is feasible to think that the use of isoflurane is not related to lesions in the central nervous system reported in other articles, and this treatment can be considered effective and safe for the control of SRSE.(AU)

Analysis of adherence to an early mobilization protocol in an intensive care unit: Data collected prospectively over a period of three years by the clinical information system / Análisis de adherencia a un protocolo de movilización precoz en una unidad de cuidados intensivos: datos recopilados prospectivamente durante un periodo de tres años por el sistema de información clínica

Objective To determinate the adherence and barriers of our early mobilization protocol in patients who had received mechanical ventilation >48h in routine daily practice through clinical information system during all Intensive Care Unit (ICU) stay. Design Observational and prospective cohort study. Setting Polyvalent ICU over a three-year period (2017–2019). Patients Adult patients on mechanical ventilation >48h who met the inclusion criteria for the early mobilization protocol. Interventions None. Main variables of interest Demographics, adherence to the protocol and putative hidden adherence, total number of mobilizations, barriers, artificial airway/ventilatory support at each mobilization level and adverse events. Results We analyzed 3269 stay-days from 388 patients with median age of 63 (51–72) years, median APACHE II 23 (18–29) and median ICU stay of 10.1 (6.2–16.5) days. Adherence to the protocol was 56.6% (1850 stay-days), but patients were mobilized in only 32.2% (1472) of all stay-days. The putative hidden adherence was 15.6% (509 stay-days) which would increase adherence to 72.2%. The most common reasons for not mobilizing patients were failure to meeting the criteria for clinical stability in 241 (42%) stay-days and unavailability of physiotherapists in 190 (33%) stay-days. Adverse events occurred in only 6 (0.4%) stay-days. Conclusions Data form Clinical Information System showed although adherence was high, patients were mobilized in only one-third of all stay-days. Knowing the specific reason why patient were not mobilized in each stay-day allow to develop concrete decisions to increase the number of mobilizations (AU)

Objetivo Determinar la adherencia y barreras del protocolo de movilización precoz en pacientes que recibieron ventilación mecánica >48 horas en la práctica diaria habitual a través del sistema de información clínica durante toda su estancia en Unidad de Cuidados Intensivos (UCI). Diseño Estudio observacional y prospectivo. Ámbito UCI polivalente durante un periodo de tres años (2017-2019). Pacientes Se incluyeron pacientes adultos en ventilación mecánica > 48 horas que cumplieron los criterios de inclusión del protocolo. Intervenciones Ninguna. Variables principales Se aplicaron variables demográficas, adherencia y adherencia oculta, número total de movilizaciones, barreras, tipo vía aérea artificial/soporte ventilatorio en cada nivel de movilización y eventos adversos. Resultados Analizamos 3.269 días de estancia de 388 pacientes con una mediana de edad de 63 (51-72) años, mediana de APACHE-II 23(18-29) y estancia en UCI mediana de 10,1 (6,2-16,5) días. La adherencia al protocolo fue del 56,6% (1.850 días de estancia), pero los pacientes se movilizaron solo el 32,2% (1.472) de todos los días de estancia. La adherencia oculta fue del 15,6% (509 días de estancia), aumentando la adherencia al 72,2%. Las causas más comunes para la no movilización fueron el incumplimiento de los criterios de estabilidad clínica en 241 (42%) días de estancia y la falta de disponibilidad de fisioterapeutas en 190 (33%) días de estancia. Los eventos adversos ocurrieron en solo 6 (0,4%) días de estancia. Conclusiones Aunque la adherencia fue alta, los pacientes se movilizaron en solo un tercio de todos los días de estancia. Conocer el motivo específico por el cual los pacientes no fueron movilizados permite desarrollar decisiones concretas para incrementar el número de movilizaciones (AU)

A differential therapeutic consideration for use of corticosteroids according to established COVID-19 clinical phenotypes in critically ill patients / Una consideración terapéutica diferencial para el uso de corticoesteroides en COVID-19 según los diferentes fenotipos clínicos establecidos en pacientes críticos

bjective To determine if the use of corticosteroids was associated with Intensive Care Unit (ICU) mortality among whole population and pre-specified clinical phenotypes. Design A secondary analysis derived from multicenter, observational study. Setting Critical Care Units. Patients Adult critically ill patients with confirmed COVID-19 disease admitted to 63 ICUs in Spain. Interventions Corticosteroids vs. no corticosteroids. Main variables of interest Three phenotypes were derived by non-supervised clustering analysis from whole population and classified as (A: severe, B: critical and C: life-threatening). We performed a multivariate analysis after propensity optimal full matching (PS) for whole population and weighted Cox regression (HR) and Fine-Gray analysis (sHR) to assess the impact of corticosteroids on ICU mortality according to the whole population and distinctive patient clinical phenotypes. Results A total of 2017 patients were analyzed, 1171 (58%) with corticosteroids. After PS, corticosteroids were shown not to be associated with ICU mortality (OR: 1.0; 95% CI: 0.98–1.15). Corticosteroids were administered in 298/537 (55.5%) patients of “A” phenotype and their use was not associated with ICU mortality (HR=0.85 [0.55–1.33]). A total of 338/623 (54.2%) patients in “B” phenotype received corticosteroids. No effect of corticosteroids on ICU mortality was observed when HR was performed (0.72 [0.49–1.05]). Finally, 535/857 (62.4%) patients in “C” phenotype received corticosteroids. In this phenotype HR (0.75 [0.58–0.98]) and sHR (0.79 [0.63–0.98]) suggest a protective effect of corticosteroids on ICU mortality. Conclusion Our finding warns against the widespread use of corticosteroids in all critically ill patients with COVID-19 at moderate dose. Only patients with the highest inflammatory levels could benefit from steroid treatment (AU)

Objetivo Evaluar si el uso de corticoesteroides (CC) se asocia con la mortalidad en la unidad de cuidados intensivos (UCI) en la población global y dentro de los fenotipos clínicos predeterminados. Diseño Análisis secundario de estudio multicéntrico observacional. Ámbito UCI. Pacientes Pacientes adultos con COVID-19 confirmado ingresados en 63 UCI de España. Intervención Corticoides vs. no corticoides. Variables de interés principales A partir del análisis no supervisado de grupos, 3 fenotipos clínicos fueron derivados y clasificados como: A grave, B crítico y C potencialmente mortal. Se efectuó un análisis multivariado después de un propensity optimal full matching (PS) y una regresión ponderada de Cox (HR) y análisis de Fine-Gray (sHR) para evaluar el impacto del tratamiento con CC sobre la mortalidad en la población general y en cada fenotipo clínico. Resultados Un total de 2.017 pacientes fueron analizados, 1.171 (58%) con CC. Después del PS, el uso de CC no se relacionó significativamente con la mortalidad en UCI (OR: 1,0; IC 95%: 0,98-1,15). Los CC fueron administrados en 298/537 (55,5%) pacientes del fenotipo A y no se observó asociación significativa con la mortalidad (HR=0,85; 0,55-1,33). Un total de 338/623 (54,2%) pacientes del fenotipo B recibieron CC sin efecto significativo sobre la mortalidad (HR=0,72; 0,49-1,05). Por último, 535/857 (62,4%) pacientes del fenotipo C recibieron CC. En este fenotipo, se evidenció un efecto protector de los CC sobre la mortalidad HR (0,75; 0,58-0,98). Conclusión Nuestros hallazgos alertan sobre el uso indiscriminado de CC a dosis moderadas en todos los pacientes críticos con COVID-19. Solamente pacientes con elevado estado de inflamación podrían beneficiarse con el tratamiento con CC (AU)

Analysis of adherence to an early mobilization protocol in an intensive care unit: Data collected prospectively over a period of three years by the clinical information system.

OBJECTIVE: To determinate the adherence and barriers of our early mobilization protocol in patients who had received mechanical ventilation >48h in routine daily practice through clinical information system during all Intensive Care Unit (ICU) stay. DESIGN: Observational and prospective cohort study. SETTING: Polyvalent ICU over a three-year period (2017-2019). PATIENTS: Adult patients on mechanical ventilation >48h who met the inclusion criteria for the early mobilization protocol. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Demographics, adherence to the protocol and putative hidden adherence, total number of mobilizations, barriers, artificial airway/ventilatory support at each mobilization level and adverse events. RESULTS: We analyzed 3269 stay-days from 388 patients with median age of 63 (51-72) years, median APACHE II 23 (18-29) and median ICU stay of 10.1 (6.2-16.5) days. Adherence to the protocol was 56.6% (1850 stay-days), but patients were mobilized in only 32.2% (1472) of all stay-days. The putative hidden adherence was 15.6% (509 stay-days) which would increase adherence to 72.2%.

Evaluación de la implantación de prácticas seguras con los medicamentos en los Servicios de Medicina Intensiva / Assessment of the implementation of safe medication practices in Intensive Medicine Units

Objetivo Conocer el grado de implantación de las prácticas seguras con los medicamentos en los Servicios de Medicina Intensiva e identificar oportunidades de mejora. Diseño Estudio descriptivo multicéntrico. Ámbito Servicios de Medicina Intensiva. Participantes/procedimiento Cuarenta Servicios de Medicina Intensiva que voluntariamente cumplimentaron el «Cuestionario de autoevaluación de la seguridad del uso de los medicamentos en los Servicios de Medicina Intensiva» entre marzo y septiembre del 2020. El cuestionario contiene 147 ítems de evaluación agrupados en 10 elementos clave. Variables principales de interés Puntuación media y porcentaje medio sobre el valor máximo posible en el cuestionario completo, en los elementos clave y en los ítems de evaluación. Resultados La puntuación media del cuestionario completo en los Servicios de Medicina Intensiva fue de 436,8 (49,2% del valor máximo posible). No se encontraron diferencias según dependencia funcional, tamaño del hospital y tipo de servicio. Los elementos clave referentes a la incorporación de farmacéuticos en estos servicios, así como a la competencia y la formación de los profesionales en prácticas de seguridad, mostraron los valores más bajos (31,2% y 33,2%, respectivamente). Otros tres elementos clave relativos a la accesibilidad a la información sobre los pacientes y los medicamentos; a la estandarización, el almacenamiento y la distribución de los medicamentos, y a los programas de calidad y gestión de riesgos mostraron porcentajes inferiores al 50%. Conclusiones Se han identificado numerosas prácticas seguras efectivas cuyo grado de implantación en los Servicios de Medicina Intensiva es bajo y que es preciso abordar para reducir los errores de medicación en el paciente crítico (AU)

Objective To assess the level of implementation of medication safety practices in Intensive Care Units (ICUs) and to identify opportunities for improvement. Design A descriptive multicenter study was carried out. Setting Intensive Care Units. Participants/procedure A total of 40 ICUs voluntarily completed the “Medication use-system safety self-assessment for Intensive Care Units” between March and September 2020. The survey comprised 147 items for evaluation grouped into 10 key elements. Main variables Calculation was made of the mean scores and mean percentages based on the maximum possible values for the overall survey, for the key elements and for each individual item for evaluation. Results The mean score of the overall questionnaire among the participating ICUs was 436.8 (49.2% of the maximum possible score). No differences were found according to functional dependence, size of the hospital or type of ICU. The key elements referred to the incorporation of clinical pharmacists in these units, as well as the competence and training of the professionals in safety practices yielded the lowest values (31.2% and 33.2%, respectively). Three other key elements related to accessibility to information about patients and medicines; to the standardization, storage and distribution of medicines; and to the quality and risk management programs, yielded percentages below 50%. Conclusions Numerous effective safety medication practices have been identified with a low level of implementation in ICUs. This situation must be addressed in order to reduce medication errors in critically ill patients (AU)

Secondary use of data extracted from a clinical information system to assess the adherence of tidal volume and its impact on outcomes.

OBJECTIVES: To extract data from clinical information systems to automatically calculate high-resolution quality indicators to assess adherence to recommendations for low tidal volume. DESIGN: We devised two indicators: the percentage of time under mechanical ventilation with excessive tidal volume (>8mL/kg predicted body weight) and the percentage of patients who received appropriate tidal volume (≤8mL/kg PBW) at least 80% of the time under mechanical ventilation. We developed an algorithm to automatically calculate these indicators from clinical information system data and analyzed associations between them and patients' characteristics and outcomes. SETTINGS: This study has been carried out in our 30-bed polyvalent intensive care unit between January 1, 2014 and November 30, 2019. PATIENTS: All patients admitted to intensive care unit ventilated >72h were included. INTERVENTION: Use data collected automatically from the clinical information systems to assess adherence to tidal volume recommendations and its outcomes. MAIN VARIABLES OF INTEREST: Mechanical ventilation days, ICU length of stay and mortality. RESULTS: Of all admitted patients, 340 met the inclusion criteria. Median percentage of time under mechanical ventilation with excessive tidal volume was 70% (23%-93%); only 22.3% of patients received appropriate tidal volume at least 80% of the time. Receiving appropriate tidal volume was associated with shorter duration of mechanical ventilation and intensive care unit stay. Patients receiving appropriate tidal volume were mostly male, younger, taller, and less severely ill. Adjusted intensive care unit mortality did not differ according to percentage of time with excessive tidal volume or to receiving appropriate tidal volume at least 80% of the time. CONCLUSIONS: Automatic calculation of process-of-care indicators from clinical information systems high-resolution data can provide an accurate and continuous measure of adherence to recommendations. Adherence to tidal volume recommendations was associated with shorter duration of mechanical ventilation and intensive care unit stay.

Objetivos Extraer los datos del Sistema de Información Clínica para calcular automáticamente indicadores de calidad de alta resolución para evaluar la adherencia a las recomendaciones sobre el volumen tidal. Diseño Ideamos 2 indicadores: el porcentaje de tiempo en ventilación mecánica con volumen tidal excesivo (>8mL/kg peso ideal) y el porcentaje de pacientes con volumen tidal apropiado (≤8mL/kg peso ideal) al menos el 80% del tiempo en ventilación mecánica. Desarrollamos un algoritmo para calcular automáticamente dichos indicadores con los datos del Sistema de Información Clínica y analizamos su asociación con las características de los pacientes y su evolución. Ambiente El estudio se llevó a cabo en una unidad de cuidados intensivos polivalente de 30 camas desde el 1 enero 2014 hasta el 20 noviembre 2019. Pacientes Se incluyeron en el estudio todos los pacientes ingresados en la unidad de cuidados intensivos conectados a ventilación mecánica>72h. Intervención Usar los datos recogidos automáticamente desde el Sistema de Información Clínica para evaluar la adherencia a las recomendaciones del volumen tidal y sus resultados. Principales variables de interés Días de ventilación mecánica, días de estancia en la unidad de cuidados intensivos y mortalidad. Resultados De todos los pacientes ingresados, 340 cumplieron los criterios de inclusión. El tiempo medio de ventilación mecánica con volumen tidal excesivo fue 70% (23-93%); solo el 22,3% de los pacientes recibió un volumen tidal apropiado al menos el 80% del tiempo. Recibir un volumen tidal apropiado se asoció con menos días de ventilación mecánica y de estancia en la unidad de cuidados intensivos. Los pacientes que recibieron un volumen tidal apropiado fueron más frecuentemente hombres, más jóvenes, más altos y menos graves (AU)

Antibióticos en desarrollo para bacilos gram negativos multirresistentes / Antibiotics in development for multiresistant gram-negative bacilli

El rápido incremento en las resistencias a los antibióticos entre los bacilos gram negativos (BGN), especialmente en cepas de enterobacterias, P. aeruginosa y A. baumannii, con elevados patrones de resistencia, plantea una enorme amenaza para los sistemas de salud en todo el mundo. En la última década diferentes antibióticos han sido desarrollados contra patrones de resistencia, algunos de los cuales combinan un β-lactámico junto con un inhibidor de β-lactamasa, mientras que otros utilizan inhibidores no β-lactámicos. La mayoría de ellos presenta una adecuada actividad in vitro sobre varias β-lactamasas de clase A, C y D de Ambler. Sin embargo, combinaciones como ceftazidime/avibactam, ceftolozano/tazobactam y meropenem/vaborbactam no presentan actividad contra metalo-β-lactamasas. Nuevas combinaciones como aztreonan/AVI, cefepime/zidebactam, o modernas cefalosporinas como cefiderocol, presentan eficacia contra casi la totalidad de las metalo-β-lactamasas. Aunque algunas de estas combinaciones ya están aprobadas y en fase de comercialización, muchas de ellas aún deben definir su lugar dentro del tratamiento de microorganismos con resistencia elevada a través de estudios clínicos (AU)

The rapid increase in antibiotic (ATB) resistance among Gram-negative bacilli(BGN), especially in strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii, with high resistance patterns (XDR), poses a huge threat to health systems worldwide. In the last decade, different ATBs have been developed against XDR, some of which combine a lactam β along with a β-lactamase inhibitor, while others use non-β-lactam inhibitors. Most of them have adequate “in vitro” activity on several β-lactamases of class A, C and D of Ambler. However, combinations such as Ceftazidime/avibactam, Ceftolozane/Tazobactam and Meropenem/vaborbactam have no activity against metallo-β-lactamases(MβL). New combinations such as Aztreonan/AVI, Cefepime/Zidebactam, or new cephalosporins such as Cefiderocol, have efficacy against MβL enzymes. Although some of these combinations are already approved and in the commercialization phase, many of them have yet to define their place within the treatment of microorganisms with high resistance through clinical studies (AU)

Antibiotics in development for multiresistant gram-negative bacilli.

The rapid increase in antibiotic(ATB) resistance among Gram-negative bacilli(BGN), especially in strains of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii, with high resistance patterns (XDR), poses a huge threat to health systems worldwide. In the last decade, different ATBs have been developed against XDR, some of which combine a lactam ß along with a ß-lactamase inhibitor, while others use non-ß-lactam inhibitors. Most of them have adequate "in vitro" activity on several ß-lactamases of class A, C and D of Ambler. However, combinations such as Ceftazidime/avibactam, Ceftolozane/Tazobactam and Meropenem/vaborbactam have no activity against metallo-ß-lactamases(MßL). New combinations such as Aztreonan/AVI, Cefepime/Zidebactam, or new cephalosporins such as Cefiderocol, have efficacy against MßL enzymes. Although some of these combinations are already approved and in the commercialization phase, many of them have yet to define their place within the treatment of microorganisms with high resistance through clinical studies.

Cross-cultural adaptation of the SCORE survey and evaluation of the impact of Real-Time Random Safety Audits in organizational culture: A multicenter study / Adaptación transcultural de la encuesta SCORE y evaluación del impacto de los análisis aleatorios de seguridad en tiempo real en la cultura organizacional: estudio multicéntrico

Objective To establish a cross-cultural adaptation of the Safety, Communication, Operational Reliability, and Engagement (SCORE) survey and to use this instrument to evaluate the impact of a safety intervention. Design Cross-cultural adaptation and before-and-after evaluation study. Setting 5 ICU. Participants Medical residents, attending physicians, and nurses at those ICU. Interventions Adaptation of the SCORE survey to Spanish culture. The adapted survey was used to assess all safety-culture-related domains before and one-year after implementing the use of a safety tool, Real-Time Random Safety Audits (in Spanish: Análisis Aleatorios de Seguridad en Tiempo Real, AASTRE). Main outcome measure Adaptabiliy of the Spanish version of SCORE survey in the ICU setting and evaluation of the effect of AASTRE on their domains. Results The cross-cultural adaptation was adequate. Post-AASTRE survey scores [mean (standard deviation, SD)] were significantly better in the domains learning environment [50.55 (SD 20.62) vs 60.76 (SD 23.66), p<.0001], perception of local leadership [47.98 (SD 23.57) vs 62.82 (SD 27.46), p<.0001], teamwork climate [51.19 (SD 18.55) vs 55.89 (SD 20.25), p=.031], safety climate [45.07 (SD 17.60) vs 50.36 (SD 19.65), p=.01], participation decision making [3 (SD 0.82) vs 3.65 (SD 0.87), p<.0001] and advancement in the organization [3.21 (SD 0.77) vs 4.04 (SD 0.77), p<.0001]. However, post-AASTRE scores were significantly worse in the domains workload and burnout climate. Conclusions The cross-cultural adaptation of the SCORE survey into Spanish is a useful tool for ICUs. The application of the AASTRE is associated with improvements in six SCORE domains, including the safety climate (AU)Objetivo

Prior influenza vaccine is not a risk factor for bacterial coinfection in patients admitted to the ICU due to severe influenza / La vacuna previa contra la influenza no es un factor de riesgo de coinfección bacteriana en pacientes ingresados en la UCI por influenza severa

Objective To determine whether the prior usage of the flu vaccine is a risk factor for bacterial co-infection in patients with severe influenza. Design This was a retrospective observational cohort study of subjects admitted to the ICU. A propensity score matching, and logistic regression adjusted for potential confounders were carried out to evaluate the association between prior influenza vaccination and bacterial co-infection. Settings 184 ICUs in Spain due to severe influenza. Patients Patients included in the Spanish prospective flu registry. Interventions Flu vaccine prior to the hospital admission. Results A total of 4175 subjects were included in the study. 489 (11.7%) received the flu vaccine prior to develop influenza infection. Prior vaccinated patients were older 71 [61–78], and predominantly male 65.4%, with at least one comorbid condition 88.5%. Prior vaccination was not associated with bacterial co-infection in the logistic regression model (OR: 1.017; 95%CI 0.803–1.288; p=0.885). After matching, the average treatment effect of prior influenza vaccine on bacterial co-infection was not statistically significant when assessed by propensity score matching (p=0.87), nearest neighbor matching (p=0.59) and inverse probability weighting (p=0.99). Conclusions No association was identified between prior influenza vaccine and bacterial coinfection in patients admitted to the ICU due to severe influenza. Post influenza vaccination studies are necessary to continue evaluating the possible benefits (AU)

Objetivo Determinar si el uso previo de la vacuna antigripal es un factor de riesgo para coinfección bacteriana en pacientes con influenza grave. Diseño Este fue un estudio de cohorte observacional retrospectivo de sujetos ingresados en la UCI. Se realizó un emparejamiento por puntuación de propensión y una regresión logística ajustada para posibles factores de confusión para evaluar la asociación entre el antecedente de vacunación contra la gripe y la coinfección bacteriana. Ámbito Ciento ochenta y cuatro ingresos en UCI españolas por gripe grave. Pacientes Pacientes incluidos en el registro prospectivo español de gripe. Intervenciones Vacuna antigripal previa al ingreso hospitalario. Resultados Se incluyó en el estudio un total de 4.175 sujetos. Recibieron la vacuna contra la influenza antes de desarrollar la infección por influenza 489 (11,7%). Los pacientes previamente vacunados eran mayores de 71 años (RIC 61-78), predominantemente varones (65,4%) y con al menos una condición comórbida (88,5%). La vacunación previa no se asoció con la coinfección bacteriana en el modelo de regresión logística (OR: 1,017; IC95% 0,803-1,288; p=0,885). Después del emparejamiento, el efecto promedio del tratamiento del antecedente de vacuna contra la influenza sobre la coinfección bacteriana no fue estadísticamente significativo cuando se evaluó mediante el emparejamiento por puntuación de propensión (p=0,87), por emparejamiento del vecino más cercano (p=0,59) y mediante la ponderación de probabilidad inversa (p=0,99). Conclusiones No se identificó asociación entre el antecedente de vacuna antigripal y coinfección bacteriana en pacientes ingresados en UCI por influenza severa. Más estudios para evaluar los efectos de la vacunación contra la gripe son necesarios para continuar evaluando los posibles beneficios (AU)

Impact of Aspergillus spp. isolation in the first 24 hours of admission in critically ill patients with severe influenza virus pneumonia.

OBJECTIVE: To determine the incidence and impact of Aspergillus spp. isolation (AI) on ICU mortality in critically ill patients with severe influenza pneumonia during the first 24h of admission. DESIGN: Secondary analysis of an observational and prospective cohort study. SETTING: ICUs voluntary participating in the Spanish severe Influenza pneumonia registry, between June 2009 and June 2019. PATIENTS: Consecutive patients admitted to the ICU with diagnosis of severe influenza pneumonia, confirmed by real-time polymerase chain reaction. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Incidence of AI in respiratory samples. Demographic variables, comorbidities, need for mechanical ventilation and the presence of shock according at admission. Acute Physiology and Chronic Health Evaluation II (APACHE II) scale calculated on ICU admission. RESULTS: 3702 patients were analyzed in this study. AI incidence was 1.13% (n=42). Hematological malignancies (OR 4.39, 95% CI 1.92-10.04); HIV (OR 3.83, 95% CI 1.08-13.63), and other immunosuppression situations (OR 4.87, 95% CI 1.99-11.87) were factors independently associated with the presence of Aspergillus spp. The automatic CHAID decision tree showed that hematologic disease with an incidence of 3.3% was the most closely AI related variable. Hematological disease (OR 2.62 95% CI 1.95-3.51), immunosuppression (OR 2.05 95% CI 1.46-2.88) and AI (OR 3.24, 95% CI 1.60-6.53) were variables independently associated with ICU mortality. CONCLUSIONS: Empirical antifungal treatment in our population may only be justified in immunocompromised patients. In moderate-high risk cases, active search for Aspergillus spp. should be implemented.
