Objetivo Conocer la epidemiología y evolución al alta de los pacientes oncológicos que precisan ingreso en UCI. Diseño Estudio descriptivo observacional de datos del registro ENVIN-HELICS combinado con variables registradas específicamente. Se comparan pacientes con y sin neoplasia. Se identifican grupos de pacientes neoplásicos con peor evolución. Ámbito UCI participantes en ENVIN-HELICS del año 2018 con participación voluntaria en el registro oncológico. Pacientes Ingresados más de 24horas. Entre estos aquellos diagnosticados de neoplasia en los últimos 5 años. Variables principales Las generales epidemiológicas del registro ENVIN-HELICS y variables relacionadas con la neoplasia. Resultados En las 92 UCI con datos completos se seleccionaron 11.796 pacientes, de los que 1.786 (15,1%) son pacientes con neoplasia. La proporción de pacientes con cáncer por unidad fue muy variable (rango: 1-48%). La mortalidad en UCI de los pacientes oncológicos fue superior a los no oncológicos (12,3% versus 8,9%; p<0,001). En pacientes oncológicos predominaron los ingresados en el postoperatorio programado (46,7%) o urgente (15,3%). Los pacientes con proceso patológico médico fueron más graves, con mayor estancia y mortalidad (27, 5%). Aquellos ingresados en UCI por enfermedad no quirúrgica relacionada con el cáncer tuvieron la mortalidad más alta (31,4%). Conclusión Existe una gran variabilidad en el porcentaje de pacientes oncológicos en las diferentes UCI. El 46,7% de los pacientes ingresa tras someterse a cirugía programada. La mayor mortalidad corresponde a pacientes con enfermedad médica (27,5%) y a los ingresados por complicaciones relacionadas con el cáncer (31,4%). (AU)

Objective To assess the epidemiology and outcome at discharge of cancer patients requiring admission to the Intensive Care Unit (ICU). Design A descriptive observational study was made of data from the ENVIN-HELICS registry, combined with specifically compiled variables. Comparisons were made between patients with and without neoplastic disease, and groups of cancer patients with a poorer outcome were identified. Setting Intensive Care Units participating in ENVIN-HELICS 2018, with voluntary participation in the oncological registry. Patients Subjects admitted during over 24hours and diagnosed with cancer in the last 5 years. Primary endpoints The general epidemiological endpoints of the ENVIN-HELICS registry and cancer-related variables. Results Of the 92 ICUs with full data, a total of 11,796 patients were selected, of which 1786 (15.1%) were cancer patients. The proportion of cancer patients per Unit proved highly variable (1-48%). In-ICU mortality was higher among the cancer patients than in the non-oncological subjects (12.3% versus 8.9%; P<.001). Elective postoperative (46.7%) or emergency admission (15.3%) predominated in the cancer patients. Patients with medical disease were in more serious condition, with longer stay and greater mortality (27.5%). The patients admitted in ICU due to nonsurgical disease related to cancer exhibited the highest mortality rate (31.4%). Conclusions Great variability was recorded in the percentage of cancer patients in the different ICUs. A total of 46.7% of the patients were admitted after undergoing scheduled surgery. The highest mortality rate corresponded to patients with medical disease (27.5%), and to those admitted due to cancer-related complications (31.4%). (AU)

Changes of resistance rates in Pseudomonas aeruginosa strains are unrelated to antimicrobial consumption in ICU populations with invasive device-related infection / Los cambios en la resistencia de cepas de Pseudomonas aeruginosa identificadas en infecciones relacionadas con dispositivos invasores no se relacionan con el consumo de antibióticos en la UCI

OBJECTIVE: To evaluate the relationship between antipseudomonal antibiotic consumption and each individual drug resistance rate in Pseudomonas aeruginosa strains causing ICU acquired invasive device-related infections (IDRI). DESIGN: A post hoc analysis was made of the data collected prospectively from the ENVIN-HELICS registry. SETTING: Intensive Care Units participating in the ENVIN-UCI registry between the years 2007 and 2016 (3-month registry each year). PATIENTS: Patients admitted for over 24h. MAIN VARIABLES: Annual linear and nonlinear trends of resistance rates of P. aeruginosa strains identified in IDRI and days of treatment of each antipseudomonal antibiotic family per 1000 occupied ICU bed days (DOT) were calculated. RESULTS: A total of 15,095 episodes of IDRI were diagnosed in 11,652 patients (6.2% out of a total of 187,100). Pseudomonas aeruginosa was identified in 2095 (13.6%) of 15,432 pathogens causing IDRI. Resistance increased significantly over the study period for piperacillin-tazobactam (P<0.001), imipenem (P=0.016), meropenem (P=0.004), ceftazidime (P=0.005) and cefepime (P=0.015), while variations in resistance rates for amikacin, ciprofloxacin, levofloxacin and colistin proved nonsignificant. A significant DOT decrease was observed for aminoglycosides (P<0.001), cephalosporins (P<0.001), quinolones (P<0.001) and carbapenems (P<0.001). CONCLUSIONS: No significant association was observed between consumption of each antipseudomonal antibiotic family and the respective resistance rates for P. aeruginosa strains identified in IDRI

OBJETIVO: Evaluar la relación entre el consumo de antibióticos antipseudomonales y la tasa de resistencia de cada fármaco individual en cepas de Pseudomonas aeruginosa aisladas en infecciones relacionadas con dispositivos invasivos (IDRI, por sus siglas en inglés) adquiridas en la unidad de cuidados intensivos (UCI). DISEÑO: Análisis post-hoc de los datos recopilados prospectivamente del registro ENVIN-HELICS. Ámbito: Las UCI que participaron en el registro ENVIN-UCI entre los años 2007-2016 (registro de 3 meses cada año). PACIENTES: Pacientes ingresados >24h. VARIABLES PRINCIPALES: Se calcularon las tendencias anuales lineales y no lineales de las tasas de resistencia de las cepas de P. aeruginosa identificadas en IDRI y los días de tratamiento de cada familia de antibióticos antipseudomonales por 1.000 días de cama ocupada en la UCI (DOT). RESULTADOS: Se diagnosticaron 15.095 episodios de IDRI en 11.652 pacientes (6,2% de 187.100). Se identificó P. aeruginosa en 2.095 (13,6%) de 15.432 patógenos que causaron IDRI. La resistencia aumentó significativamente durante el período de estudio para piperacilina-tazobactam (p < 0,001), imipenem (p = 0,016), meropenem (p = 0,004), ceftazidima (p = 0,005) y cefepima (p = 0,015), mientras que las variaciones en las tasas de resistencia de amikacina, ciprofloxacina, levofloxacina y colistina no fueron significativas. Se observó una disminución significativa de la DOT para aminoglucósidos (p < 0,001), cefalosporinas (p < 0,001), quinolonas (p < 0,001) y carbapenems (p < 0,001). CONCLUSIONES: No se encontró asociación significativa del consumo de cada familia de antibióticos antipseudomonales con sus respectivas tasas de resistencia para las cepas de P. aeruginosa identificadas en IDRI

¿Es necesario un proyecto para prevenir las infecciones del tracto urinario en los pacientes ingresados en unidades de cuidados intensivos españolas? / Is a project needed to prevent urinary tract infection in patients admitted to spanish ICUs?

Objetivo: Analizar los datos epidemiológicos de las infecciones del tracto urinario relacionadas con sonda uretral (ITU-SU) en pacientes críticos ingresados en UCI españolas para evaluar la necesidad de aplicar un programa de intervención a nivel nacional para disminuir dichas infecciones. Diseño: Análisis retrospectivo, no intervencionista, de prevalencia de periodo anual. Ámbito: UCI participantes en el registro multicéntrico ENVIN-UCI entre los años 2007-2016. Pacientes: Pacientes críticos ingresados en UCI con ITU-SU. Variables principales: Tasa de incidencia por 1.000 días de utilización de SU; ratio de uso de SU; proporción de ITU-SU con respecto del total de infecciones relacionadas con asistencia sanitaria (IRAS) controladas en el registro. Resultados: Se han incluido 187.100 pacientes de los que 137.654 (73,6%) utilizaron SU durante 1.215.673 días (84,4% de los días de estancia en UCI). En 4.539 (3,3%) pacientes sondados se han diagnosticado 4.977 ITU-SU (3,6 episodios por 100 pacientes con SU). La tasa de incidencia de ITU-SU ha disminuido entre los años 2007 y 2016 un 19% (4,69 a 3,8 episodios por 1.000 días de SU), aunque se ha mantenido la ratio de uso de SU (0,84 [0,82-0,86]). La proporción de las ITU-SU ha aumentado desde el 23,3% al 31,9% del total de IRAS controladas. Conclusiones: Aunque han disminuido las tasas de ITU-SU estas infecciones han pasado a ser, proporcionalmente, la primera de las IRAS en UCI. Persiste una elevada ratio de utilización de SU en UCI españolas. Existe un espacio de mejora, por lo que un proyecto ITU-ZERO podría ser útil en nuestro país

Objective: To analyze epidemiological data of catheter-associated urinary tract infection (CAUTI) in critically ill patients admitted to Spanish ICUs in order to assess the need of implementing a nationwide intervention program to reduce these infections. Design: Non-intervention retrospective annual period prevalence analysis. Setting: Participating ICUs in the ENVIN-UCI multicenter registry between the years 2007-2016. Patients: Critically ill patients admitted to the ICU with catheter-associated urinary tract infection (CAUTI). Main variables: Incidence rates per 1,000 catheter-days; urinary catheter utilization ratio; proportion of CAUTIs in relation to total health care-associated infections (HAIs). Results: A total of 187,100 patients, 137,654 (73.6%) of whom had a urinary catheter in place during 1,215,673 days (84% of days of ICU stay) were included. In 4,539 (3.3%) patients with urinary catheter, 4,977 CAUTIs were diagnosed (3.6 episodes per 100 patients with urinary catheter). The CAUTI incidence rate showed a 19% decrease between 2007 and 2016 (4.69 to 3.8 episodes per 1,000 catheter-days), although a sustained urinary catheter utilization ratio was observed (0.84 [0.82-0.86]). The proportion of CAUTI increased from 23.3% to 31.9% of all HAIs controlled in the ICU. Conclusions: Although CAUTI rates have declined in recent years, these infections have become proportionally the first HAIs in the ICU. The urinary catheter utilization ratio remains high in Spanish ICUs. There is room for improvement, so that a CAUTI-ZERO project in our country could be useful

Document on the state of affairs of the Spanish model of Intensive Care Medicine. SEMICYUC Strategic Plan 2018-2022. / Documento sobre la situación del modelo español de Medicina Intensiva. Plan estratégico SEMICYUC 2018-2022.

The role of Critical Care Medicine in Spain requires continuous revision and reflection. We have values and strengths that are evidenced in our daily work and by their important effects in routine hospital activity. Other medical specialties seeking to assume activities referred to critical patient care, as well as a number of other circumstances, may have a negative impact upon our routine duties. This article reflects the impressions of an important number of members of the Planning, Organization and Management Task Force of the Spanish Society of Critical Medicine Society (Grupo de Trabajo de Planificación, Organización y Gestión; GTPOG-SEMICYUC). The actions required to upgrade our Critical Care Medicine model are presented, evolving towards a broader view such as the 'ICU without walls' or 'Expanded ICU'. The subject is addressed from three complementary standpoints: actions involving the administrative authorities; actions required on the part of our scientific Society; and initiatives to be implemented locally in each Intensive Care Unit (led by the corresponding Unit representatives) at both hospital level and involving the regional authorities.

Invasive device-associated infections caused by Pseudomonas aeruginosa in critically ill patients: evolution over 10 years.

Invasive device-associated infections caused by Pseudomonas aeruginosa over 10 years (2007-2016) were assessed based on data from the ENVIN-HELICS registry (200 Spanish intensive care units). P. aeruginosa was the leading pathogen except in the last two years in which there was a slight decrease, with Escherichia coli as the leading aetiology. The rate of infections caused by P. aeruginosa remained between 12.0% and 14.6% throughout the study period. There was a significant increase of isolates resistant to imipenem, meropenem, ceftazidime, cefepime, and piperacillin-tazobactam. Multidrug-resistant and the sum of extensively drug- and pandrug-resistant strains also increased. Resistance to anti-pseudomonal antimicrobials remains a matter of concern.

Landmark prediction of nosocomial infection risk to disentangle short- and long-stay patients.

Length of stay is one of the key determinants for the risk of nosocomial infections. The distribution of this at-risk time is heavily skewed and depends on discharge or death. This study applied landmark competing risk prediction models to account for a large proportion of short-stay patients and a small proportion of long-stay patients.

Analysis of Clinical Cohort Data Using Nested Case-control and Case-cohort Sampling Designs. A Powerful and Economical Tool.

BACKGROUND: Sampling from a large cohort in order to derive a subsample that would be sufficient for statistical analysis is a frequently used method for handling large data sets in epidemiological studies with limited resources for exposure measurement. For clinical studies however, when interest is in the influence of a potential risk factor, cohort studies are often the first choice with all individuals entering the analysis. OBJECTIVES: Our aim is to close the gap between epidemiological and clinical studies with respect to design and power considerations. Schoenfeld's formula for the number of events required for a Cox' proportional hazards model is fundamental. Our objective is to compare the power of analyzing the full cohort and the power of a nested case-control and a case-cohort design. METHODS: We compare formulas for power for sampling designs and cohort studies. In our data example we simultaneously apply a nested case-control design with a varying number of controls matched to each case, a case cohort design with varying subcohort size, a random subsample and a full cohort analysis. For each design we calculate the standard error for estimated regression coefficients and the mean number of distinct persons, for whom covariate information is required. RESULTS: The formula for the power of a nested case-control design and the power of a case-cohort design is directly connected to the power of a cohort study using the well known Schoenfeld formula. The loss in precision of parameter estimates is relatively small compared to the saving in resources. CONCLUSIONS: Nested case-control and case-cohort studies, but not random subsamples yield an attractive alternative for analyzing clinical studies in the situation of a low event rate. Power calculations can be conducted straightforwardly to quantify the loss of power compared to the savings in the num-ber of patients using a sampling design instead of analyzing the full cohort.

[Respiratory infections caused by Aspergillus spp. in critically ill patients admitted to the intensive care units]. / Infecciones respiratorias por Aspergillus spp. en pacientes críticos ingresados en unidades de cuidados intensivos.

UNLABELLED: The presence of respiratory fungal infection in the critically ill patient is associated with high morbidity and mortality. OBJECTIVES: To assess the incidence of respiratory infection caused by Aspergillus spp. independently of the origin of infection in patients admitted to Spanish ICUs, as well as to describe the rates, characteristics, outcomes and prognostic factors in patients with this type of infection. MATERIAL AND METHODS: An observational, retrospective, open-label and multicenter study was carried out in a cohort of patients with respiratory infection caused by Aspergillus spp. admitted to Spanish ICUs between 2006 and 2012 (months of April, May and June), and included in the ENVIN-HELICS registry (108,244 patients and 825,797 days of ICU stay). Variables independently related to in-hospital mortality were identified by multiple logistic regression analysis. RESULTS: A total of 267 patients from 79 of the 198 participating ICUs were included (2.46 cases per 1000 ICU patients and 3.23 episodes per 10,000 days of ICU stay). From a clinical point of view, infections were classified as ventilator-associated pneumonia in 93 cases (34.8%), pneumonia unrelated to mechanical ventilation in 120 cases (44.9%), and tracheobronchitis in 54 cases (20.2%). The study population included older patients (mean 64.8±17.1 years), with a high severity level (APACHE II score 22.03±7.7), clinical diseases (64.8%) and prolonged hospital stay before the identification of Aspergillus spp. (median 11 days), transferred to the ICU mainly from hospital wards (58.1%) and with high ICU (57.3%) and hospital (59.6%) mortality rates, exhibiting important differences depending on the type of infection involved. Independent mortality risk factors were previous admission to a hospital ward (OR=7.08, 95%CI: 3.18-15.76), a history of immunosuppression (OR=2.52, 95%CI: 1.24-5.13) and severe sepsis or septic shock (OR=8.91, 95%CI: 4.24-18.76). CONCLUSIONS: Respiratory infections caused by Aspergillus spp. in critically ill patients admitted to the ICU in Spain are infrequent, and affect a very selected group of patients, characterized by high mortality and conditioned by non-modifiable risk factors.

Quality control of the surveillance programme of ICU-acquired infection (ENVIN-HELICS registry) in Spain.

BACKGROUND: Data validation is an essential aspect for the accuracy of a nosocomial infection surveillance registry. AIM: To report the results of the first quality control programme in the national surveillance programme of intensive care unit (ICU)-acquired infection in Spain (ENVIN-HELICS registry). METHOD: During 2008, of 13,824 records included in the database, 1500 (10.8%) registries from 20 ICUs were reviewed. These ICUs were selected at random and stratified according to the number of cases included in the registry. The proportion of infected patients, which was 9.6% [95% confidence interval (CI) 8.09-11.16], was maintained during the selection of cases for review. Two physicians were trained for the purpose of the study and undertook the review. RESULTS: Overall sensitivity, specificity and positive and negative predictive values of the ENVIN-HELICS registry for the identification of patients with any device-related infection acquired during their ICU stay were 86.0% (95% CI 80.0-92.0), 98.7% (95% CI 82.19-93.6), 87.9% (95% CI 82.19-93.6) and 98.5% (95% CI 97.8-99.2), respectively, with a kappa index of 0.85 (95% CI 0.79-0.92). Secondary bloodstream infection had the lowest sensitivity (59.3%), and intubation-associated pneumonia had the highest sensitivity (86.3%). CONCLUSION: There was good correlation between data reported by the registrars and data validated by auditors, confirming the reliability of the ENVIN-HELICS registry.

Epidemiologia de las bacteriemias primarias y relacionadas con cateteres vasculares en pacientes criticos ingresados en servicios de medicina intensiva / Epidemiology of the primary and vascular catheter-related bacteriemias in critical patients admitted to an Intensive Medicine Department

Objetivo: En los últimos años se han producido cambios en el entorno de la bacteriemia relacionada con el uso de catéteres vasculares (BCV) con la aparición de cocos grampositivos multirresistentes (CGP-MR), el conocimiento de limitaciones en los antibióticos más utilizados para su tratamiento (glucopéptidos) y la aparición de nuevos antibióticos activos vs. dichos patógenos. En este artículo se analiza la evolución de las tasas, etiologías y marcadores de multirresistencia de los patógenos más comunesen las BCV (incluidas las bacteriemias primarias) en servicios de medicina intensiva españoles (UCI). Material y métodos: Estudio de incidencia, multicéntrico, prospectivo, observacional y de participación voluntaria. Han colaborado 74, 105, 112 y 121 UCI pertenecientes a 71, 97, 103 y 112 hospitales respectivamente entre los años 2005-2008 (ambos inclusive). Se ha utilizado la información incluida en el registro ENVIN-HELICS. Resultados: Las tasas de esta complicación han disminuido y se sitúan en torno a 5 episodios por 1.000 días de catéter venoso central (CVC). Una tercera parte de los episodios se presentan con una importante respuesta sistémica (sepsis grave o shock séptico). Los CGP-MR fueron los más frecuentes pero los bacilos gramnegativos (BGN) se identificaron en el 30% de casos y los hongos (distintas especies de Candida) en el 6%. Los Staphylococcus epidermidis y Staphylococcus coagulasa negativa (SCN) resistentes a meticilina persisten en una proporción superior al 80%, mientras que han disminuido los S aureus resistentes a meticilina a menos del 40%. Conclusiones: El tratamiento empírico en situaciones de extrema gravedad se considera la cobertura de los patógenos más frecuentes como son los CGP-MR y los BGN y en situaciones especiales los hongos (AU)

Objective: In recent years, changes have occurred in the setting of bacteriemia related with the use of vascular catheters (BVC) and with the appearance of multiresistant gram positive cocci (MR-GPC), knowledge of the limitations regarding the antibiotics used most for their treatment (glycopeptides) and the appearance of new antibiotics active against these pathogens. This article analyzes the evolution of the rates, etiologies and markers of multiresistance of the most common pathogens in the BVC (including the primary bacteriemias) in the Spanish Intensive Medicine Departments (ICU). Material and methods: A multicenter, prospective, observational study of incidence, with voluntary participation, was conducted. A total of 74, 105, 112 and 121 ICUs belonging to 71, 97, 103 and 112 hospitals, respectively, collaborated including the years 2005-2008. The information included in the ENVIN-HELICS registry was used. Results: The rates of this complication have decreased and are now at about 5 episodes per 1,000 days of central venous catheter (CVC). One third of the episodes occur with significant systemic response (severe sepsis or septic shock). The MR-GPC were the most frequent, however Gram-negative bacilli (GNB) were identified in 30% of the cases and fungi (different species of Candida) in 6%. Staphylococcus epidermidis and coagulase-negative, methicillin-resistant staphylococci (CNS) persist in a proportion greater than 80%, while methicillin-resistance S. aureus have decreased to less than 40%. Conclusions: The empirical treatment in situations of extreme seriousness should consider coverage of the most frequent pathogens such as the MR-GPC and GNB and in special conditions, the fungi (AU)

[GEIPC-SEIMC and GTEI-SEMICYUC recommendations for antibiotic treatment of gram positive coccal infections in the critical patient]. / Recomendaciones GEIPC-SEIMC y GTEI-SEMICYUC para el tratamiento antibiótico de infecciones por cocos grampositivos en el paciente crítico.

In recent years, an increment of infections caused by gram-positive cocci has been documented in nosocomial and hospital-acquired infections. In diverse countries, a rapid development of resistance to common antibiotics against gram-positive cocci has been observed. This situation is exceptional in Spain but our country might be affected in the near future. New antimicrobials active against these multi-drug resistant pathogens are nowadays available. It is essential to improve our current knowledge about pharmacokinetic properties of traditional and new antimicrobials to maximize its effectiveness and to minimize toxicity. These issues are even more important in critically ill patients because inadequate empirical therapy is associated with therapeutic failure and a poor outcome. Experts representing two scientific societies (Grupo de estudio de Infecciones en el Paciente Critico de la SEIMC and Grupo de trabajo de Enfermedades Infecciosas de la SEMICYUC) have elaborated a consensus document based on the current scientific evidence to summarize recommendations for the treatment of serious infections caused by gram-positive cocci in critically ill patients.

[Summary of the GEIPC-SEIMC and GTEI-SEMICYUC recommendations for the treatment of infections caused by gram positive cocci in critical patients]. / Resumen de las recomendaciones GEIPC-SEIMC y GTEI-SEMICYUC para el tratamiento antibiótico de infecciones por cocos gram positivos en la paciente crítico

OBJECTIVE: In recent years there has been an increase in infections caused by gram-positive cocci in critical patients, together with a rapid development of resistance to the antibiotics which are normally used to treat them. The objective is to prepare an antibiotic treatment guide for the most common infections caused by gram positive cocci in critical patients. This guide will help in the decision-making process regarding the care of such patients. METHOD: Experts from two scientific societies worked together to prepare a consensus document. They were members of the Study Group on Infections in Critical Patients (GEIPC), which is part of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), and the Infectious Diseases Working Group (GTEI), belonging to the Spanish Society of Intensive Care Medicine and Coronary Units (SEMICYUC). There was a systematic review of the literature published up to September 2006 regarding this type of infections and the antibiotic treatments marketed to that date. An evidence grading system was applied according to the strength of the recommendation (categories A, B or C) and the level of evidence (categories I, II or III). Recommendations were given if there was consensus among the experts from both societies. RESULTS: The antibiotic regimens recommended for treating infections caused by gram-positive cocci were presented in the form of tables, showing the recommendation grade. Alternatives were given for allergic patients. The scientific basis supporting the aforementioned recommendations is explained within the text and the references upon which they are based are cited. CONCLUSIONS: A summary of an evidence-based practical guide for the treatment of infections caused by gram-positive cocci in critical patients is presented.

Recomendaciones de la 7ª Conferencia de Consenso de la SEMICYUC. Pancreatitis aguda grave en Medicina Intensiva / Recommendations of the 7th consensus conference of the SEMICYUC. Severe acute pancreatitis in Intensive Medicine

Objetivo. La pancreatitis aguda grave (PAG) no se ha estudiado desde la Medicina Intensiva y menos su manejo integral. El objetivo es consensuar el diagnóstico y tratamiento en una UCI, con todas las Sociedades implicadas y ofrecer unas recomendaciones que uniformicen el manejo integral de las PAG. Ámbito. Español. Pamplona, 11 y 12 de marzo de 2004. Participantes. Intensivistas nacionales, gastroenterólogos de la Asociación Española de Gastroenterología (AEGE) y Club Español Biliopancreático (CEBP), cirujanos de la Asociación Española de Cirugía, Sección de Infección Quirúrgica (IQ-AEC), radiólogos de la Sociedad Española de Radiología Médica (SERAM), y Sección de Imagen Abdominal (SEDIA) y miembros de la Sociedad Española de Medicina de Urgencias y Emergencias (SEMES). Niveles de evidencia y grados de recomendación. Se eligieron las escalas del Oxford Centre for Evidence based Medicine. Elaboración de las recomendaciones. Se realizó una convocatoria pública en la que se discutieron todos los temas previamente seleccionados, que se distribuyeron en 4 bloques de preguntas: 1.ª ¿Diagnóstico, criterios precoces de gravedad y de ingreso de las PAG en UCI?. 2.ª ¿Cuáles son las medidas más relevantes y aplicables en el tratamiento del paciente con PAG en UCI?. 3.ª ¿Cuál es el tratamiento actual de la PAG?. 4.ª ¿Qué actitud quirúrgica se debe adoptar ante la PAG con necrosis no-infectada y la sepsis pancreática? Tras la discusión pública el Jurado elaboró un documento de recomendaciones. Este documento fue enviado para su comentario a los miembros del Comité Organizador, a los ponentes y a los asistentes a la Conferencia de Consenso. Por último, las recomendaciones fueron de nuevo discutidas en una sesión pública y abierta en el Congreso Nacional de la SEMICYUC. Conclusiones. Recomendaciones en PAG entre las que destacamos: la disminución de la mortalidad de la PAG depende de la estratificación temprana de las formas graves a la puerta del hospital, durante las primeras 48-96 horas y del ingreso precoz en Intensivos. Los pacientes que muestran un progresivo deterioro orgánico, aunque no precisen soporte ventilatorio, deben ingresar en UCI. Cada Centro debe consensuar un protocolo interdisciplinario. Los antibióticos como profilaxis no tienen una base de evidencia potente sólo estarían indicados en las formas necrotizantes y a la espera de un nuevo ensayo doble-ciego con meropenem en marcha. El tratamiento quirúrgico se indica en la necrosis pancreática infectada o absceso identificadas por radiología o punción radiodirigida. El manejo de las formas estériles debe ser conservador

Objective. Severe acute pancreatitis (SAP) has not been studied from the point of view of Intensive Medicine and even less its integral management. The objective is to reach a consensus on the diagnosis and treatment in an ICU with all the societies involved and to offer some recommendations that make the integral management of SAP uniform. Scope. Spanish. He took place in Pamplona, the 11-12 March 2004. Participants. National Intensivists, Gastroenterologists of the Spanish Association of Gastroenterology (AEGE) and Biliopancreatic Spanish Club (CEBP), Surgeons of the Spanish Association of Surgery, Surgical Infection Section (IQ-AEC), Radiologists of the Spanish Society of Medical Radiology (SERAM), and Abdominal Image Section (SEDIA) as well as member of the Spanish Society of Urgency and Emergency Medicine (SEMES). Evidence levels and recommendation grades. The Oxford Centre for Evidence based Medicine scales were chosen. Elaboration of the recommendations. A public examination session was called in which all the previously selected subjects were discussed. They were distributed into 4 blocks of questions: 1) Diagnostic, Early Severity criteria and Admission of SAP in the ICU? 2) What are the most relevant and applicable measures in the treatment of the patients with SAP in the ICU? 3) What is the present treatment of SAP? 4) What surgical attitude should be adopted in the face of SAP with non-infected necrosis and pancreatic sepsis? After the public discussion, the Jury elaborated a recommendations document. This document was sent to the members of the Organizing Committee, to the speakers and those attending the consensus Conference for their comments. Finally, the recommendations were discussed again in a public and open session in the National Congress of SEMICYUC.Conclusions. Recommendations in SAP, among which we emphasize: Decrease in mortality of SAP depends on the early stratifying of the serious forms to the hospital door, during the first 48-96 hours and early admission in Intensive Care. Patient who have a progressive organic deterioration, although they do not require ventilatory support, should be admitted to the ICU. Each Center should agree on an interdisciplinary protocol. Antibiotics as prophylaxis do not have a strong evidence base. They would only be indicated in necrotizing forms and while waiting for a new on-going double blind clinical trial with meropenem. Surgical treatment is indicated in infected pancreatic necrosis or abscess, identified by radiology or radioguided puncture. Management of the sterile forms should be conservative
