RESUMO

OBJECTIVE: To validate the unsupervised cluster model (USCM) developed during the first pandemic wave in a cohort of critically ill patients from the second and third pandemic waves. DESIGN: Observational, retrospective, multicentre study. SETTING: Intensive Care Unit (ICU). PATIENTS: Adult patients admitted with COVID-19 and respiratory failure during the second and third pandemic waves. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Collected data included demographic and clinical characteristics, comorbidities, laboratory tests and ICU outcomes. To validate our original USCM, we assigned a phenotype to each patient of the validation cohort. The performance of the classification was determined by Silhouette coefficient (SC) and general linear modelling. In a post-hoc analysis we developed and validated a USCM specific to the validation set. The model's performance was measured using accuracy test and area under curve (AUC) ROC. RESULTS: A total of 2330 patients (mean age 63 [53-82] years, 1643 (70.5%) male, median APACHE II score (12 [9-16]) and SOFA score (4 [3-6]) were included. The ICU mortality was 27.2%. The USCM classified patients into 3 clinical phenotypes: A (n = 1206 patients, 51.8%); B (n = 618 patients, 26.5%), and C (n = 506 patients, 21.7%). The characteristics of patients within each phenotype were significantly different from the original population. The SC was -0.007 and the inclusion of phenotype classification in a regression model did not improve the model performance (0.79 and 0.78 ROC for original and validation model). The post-hoc model performed better than the validation model (SC -0.08). CONCLUSION: Models developed using machine learning techniques during the first pandemic wave cannot be applied with adequate performance to patients admitted in subsequent waves without prior validation.

RESUMO

OBJECTIVE: To evaluate the impact of obesity on ICU mortality. DESIGN: Observational, retrospective, multicentre study. SETTING: Intensive Care Unit (ICU). PATIENTS: Adults patients admitted with COVID-19 and respiratory failure. INTERVENTIONS: None. PRIMARY VARIABLES OF INTEREST: Collected data included demographic and clinical characteristics, comorbidities, laboratory tests and ICU outcomes. Body mass index (BMI) impact on ICU mortality was studied as (1) a continuous variable, (2) a categorical variable obesity/non-obesity, and (3) as categories defined a priori: underweight, normal, overweight, obesity and Class III obesity. The impact of obesity on mortality was assessed by multiple logistic regression and Smooth Restricted cubic (SRC) splines for Cox hazard regression. RESULTS: 5,206 patients were included, 20 patients (0.4%) as underweight, 887(17.0%) as normal, 2390(46%) as overweight, 1672(32.1) as obese and 237(4.5%) as class III obesity. The obesity group patients (n = 1909) were younger (61 vs. 65 years, p < 0.001) and with lower severity scores APACHE II (13 [9-17] vs. 13[10-17, p < 0.01) than non-obese. Overall ICU mortality was 28.5% and not different for obese (28.9%) or non-obese (28.3%, p = 0.65). Only Class III obesity (OR = 2.19, 95%CI 1.44-3.34) was associated with ICU mortality in the multivariate and SRC analysis. CONCLUSIONS: COVID-19 patients with a BMI > 40 are at high risk of poor outcomes in the ICU. An effective vaccination schedule and prolonged social distancing should be recommended.

RESUMO

Nosocomial pneumonia, or hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP) are important health problems worldwide, with both being associated with substantial morbidity and mortality. HAP is currently the main cause of death from nosocomial infection in critically ill patients. Although guidelines for the approach to this infection model are widely implemented in international health systems and clinical teams, information continually emerges that generates debate or requires updating in its management. This scientific manuscript, written by a multidisciplinary team of specialists, reviews the most important issues in the approach to this important infectious respiratory syndrome, and it updates various topics, such as a renewed etiological perspective for updating the use of new molecular platforms or imaging techniques, including the microbiological diagnostic stewardship in different clinical settings and using appropriate rapid techniques on invasive respiratory specimens. It also reviews both Intensive Care Unit admission criteria and those of clinical stability to discharge, as well as those of therapeutic failure and rescue treatment options. An update on antibiotic therapy in the context of bacterial multiresistance, in aerosol inhaled treatment options, oxygen therapy, or ventilatory support, is presented. It also analyzes the out-of-hospital management of nosocomial pneumonia requiring complete antibiotic therapy externally on an outpatient basis, as well as the main factors for readmission and an approach to management in the emergency department. Finally, the main strategies for prevention and prophylactic measures, many of them still controversial, on fragile and vulnerable hosts are reviewed.

RESUMO

BACKGROUND: Regardless of the available antifungals, intraabdominal candidiasis (IAC) mortality continues to be high and represents a challenge for clinicians. MAIN BODY: This opinion paper discusses alternative antifungal options for treating IAC. This clinical entity should be addressed separately from candidemia due to the peculiarity of the required penetration of antifungals into the peritoneal cavity. Intraabdominal concentrations may be further restricted in critically ill patients where pathophysiological facts alter normal drug distribution. Echinocandins are recommended as first-line treatment in guidelines for invasive candidiasis. However, considering published data, our pharmacodynamic analysis suggests the required increase of doses, postulated by some authors, to attain adequate pharmacokinetic (PK) levels in peritoneal fluid. Given the limited evidence in the literature on PK/PD-based treatments of IAC, an algorithm is proposed to guide antifungal treatment. Liposomal amphotericin B is advocated as first-line therapy in patients with sepsis/septic shock presenting candidemia or endophthalmitis, or with prior exposure to echinocandins and/or fluconazole, or with infections by Candida glabrata. Other situations and alternatives, such as new compounds or combination therapy, are also analysed. CONCLUSION: There is a critical need for more robust clinical trials, studies examining patient heterogeneity and surveillance of antifungal resistance to enhance patient care and optimise treatment outcomes. Such evidence will help refine the existing guidelines and contribute to a more personalised and effective approach to treating this serious medical condition. Meanwhile, it is suggested to broaden the consideration of other options, such as liposomal amphotericin B, as first-line treatment until the results of the fungogram are available and antifungal stewardship could be implemented to prevent the development of resistance.

RESUMO

BACKGROUND: Controlled donation after circulatory determination of death (cDCD) seems an effective way to mitigate the critical shortage of available organs for transplant worldwide. As a recently developed procedure for organ retrieval, some questions remain unsolved such as the uncertainty regarding the effect of functional warm ischemia time (FWIT) on organs´ viability. METHODS: We developed a multicenter prospective cohort study collecting all data from evaluated organs during cDCD from 2017 to 2020. All the procedures related to cDCD were performed with normothermic regional perfusion. The analysis included organ retrieval as endpoint and FWIT as exposure of interest. The effect of FWIT on the likelihood for organ retrieval was evaluated with Relative distribution analysis. RESULTS: A total amount of 507 organs´ related information was analyzed from 95 organ donors. Median donor age was 62 years, and 63% of donors were male. Stroke was the most common diagnosis before withdrawal of life-sustaining therapy (61%), followed by anoxic encephalopathy (21%). This analysis showed that length of FWIT was inversely associated with organ retrieval rates for liver, kidneys, and pancreas. No statistically significant association was found for lungs. CONCLUSIONS: Results showed an inverse association between functional warm ischemia time (FWIT) and retrieval rate. We also have postulated optimal FWIT's thresholds for organ retrieval. FWIT for liver retrieval remained between 6 and less than 11 min and in case of kidneys and pancreas, the optimal FWIT for retrieval was 6 to 12 min. These results could be valuable to improve organ utilization and for future analysis.

RESUMO

The aim of this study was to establish practical recommendations for the diagnosis and treatment of influenza-associated invasive aspergillosis (IAPA) based on the available evidence and experience acquired in the management of patients with COVID-19-associated pulmonary aspergillosis (CAPA). The CAPA/IAPA expert group defined 14 areas in which recommendations would be made. To search for evidence, the PICO strategy was used for both CAPA and IAPA in PubMed, using MeSH terms in combination with free text. Based on the results, each expert developed recommendations for two to three areas that they presented to the rest of the group in various meetings in order to reach consensus. As results, the practical recommendations for the management of CAPA/IAPA patients have been grouped into 12 sections. These recommendations are presented for both entities in the following situations: when to suspect fungal infection; what diagnostic methods are useful to diagnose these two entities; what treatment is recommended; what to do in case of resistance; drug interactions or determination of antifungal levels; how to monitor treatment effectiveness; what action to take in the event of treatment failure; the implications of concomitant corticosteroid administration; indications for the combined use of antifungals; when to withdraw treatment; what to do in case of positive cultures for Aspergillus spp. in a patient with severe viral pneumonia or Aspergillus colonization; and how to position antifungal prophylaxis in these patients. Available evidence to support the practical management of CAPA/IAPA patients is very scarce. Accumulated experience acquired in the management of CAPA patients can be very useful for the management of IAPA patients. The expert group presents eminently practical recommendations for the management of CAPA/IAPA patients.

RESUMO

Fungal infections have become a common threat in Intensive Care Units (ICU). The epidemiology of invasive fungal diseases (IFD) has been extensively studied in patients severely immunosuppressed over the last 20-30 years, however, the type of patients that have been admitted to hospitals in the last decade has made the healthcare system and ICU a different setting with more vulnerable hosts. Patients admitted to an ICU tend to have older age and higher severity of disease. Moreover, the number of patients being treated in ICU are often immunosuppressed as a result of the widespread use of immunomodulatory agents, such as corticosteroids, chemotherapy, and biological agents. The development of Invasive Pulmonary aspergillosis (IPA) reflects a different clinical trajectory to affected patients. The increasing use of corticosteroids would probably explain the higher incidence of IPA especially in critically ill patients. In refractory septic shock, severe community-acquired pneumonia (SCAP), and acute respiratory distress syndrome (ARDS), the use of corticosteroids has re-emerged in order to decrease unacceptably high mortality rates associated with these clinical conditions. It is also pertinent to note that different reports have used different diagnosis criteria, and this might explain the different incidence rates. Another layer of complexity to better understand current IPA data is related to more aggressive acquisition of samples through invasive respiratory examinations.

RESUMO

Infections due to Klebsiella pneumoniae have been increasing in intensive care units (ICUs) in the last decade. Such infections pose a serious problem, especially when antimicrobial resistance is present. We created a task force of experts, including specialists in intensive care medicine, anaesthesia, microbiology and infectious diseases, selected on the basis of their varied experience in the field of nosocomial infections, who conducted a comprehensive review of the recently published literature on the management of carbapenemase-producing Enterobacterales (CPE) infections in the intensive care setting from 2012 to 2022 to summarize the best available treatment. The group established priorities regarding management, based on both the risk of developing infections caused by K. pneumoniae and the risk of poor outcome. Moreover, we reviewed and updated the most important clinical entities and the new antibiotic treatments recently developed. After analysis of the priorities outlined, this group of experts established a series of recommendations and designed a management algorithm.

RESUMO

Quick Pitt (qPitt), which includes temperature, systolic blood pressure, respiratory rate, cardiac arrest, and mental status, is a new prognostic score derived from the Pitt Bacteremia score. The aim of our study is to compare qPitt with quick SOFA (qSOFA) and SOFA for scoring of severity in patients with urinary tract infection (UTI). Prospective observational study of patients diagnosed with UTI. Area under the ROC curve, sensibility, and specificity to predict 30-day mortality were calculated for qPitt, qSOFA and SOFA and compared. 382 UTI cases were analyzed. Thirty-day mortality (18.8% vs. 5.9%, p < 0.001) and longer hospital stay (6 [1-11] vs. 4 [1-7] days, p < 0.001) were associated with qPitt ≥ 2. However, qPitt had a worse performance to predict 30-day mortality compared to qSOFA and SOFA (AUROC 0.692 vs. 0.832 and 0.806, respectively, p = 0.010 and p = 0.041). The sensitivity of qPitt was lower than the sensitivity of qSOFA and SOFA (70.45 vs. 84.09 for both qSOFA and SOFA, p < 0.001), with a specificity lower than qSOFA and similar to SOFA (60.36 vs. 82.25 and 63.61, p < 0.001 and p = 0.742, respectively). Quick Pitt had moderate prognostic accuracy and performed worse than qSOFA and SOFA scores for predicting mortality in patients with UTI.

RESUMO

INTRODUCTION: Quick [Sepsis-related] Sequential Organ Failure Assessment (qSOFA) is a prognostic score based on sepsis-3 definition, easy to carry out, whose application has been studied in older adults with sepsis from different sources and respiratory sepsis. However, to date no study has analysed its prognostic accuracy in older adults admitted to hospital with community urinary tract infection. METHODS: In a prospective study of 282 older adults admitted to hospital with community acquired urinary tract infection, the application of qSOFA to predict hospital mortality was analysed. The predictive capacity of qSOFA for in-hospital mortality was compared with Systemic Inflammatory Response Syndrome score (SIRS) and Sequential Organ Failure Assessment (SOFA), which require laboratory test in order to be calculated. RESULTS: In a population with a median age of 81 years, where 51.8% were males and 10.6% had septic shock, qSOFA showed sensibility and specificity of 88.46 and 75.78% and area under the receiver operating characteristic curves (AUROC) of 0.810. AUROC for qSOFA was significantly higher than that of SIRS (AUROC 0.597, P = .005) and with no statistical differences with SOFA (AUROC 0.841, P = .635). CONCLUSION: qSOFA showed a better predictive prognostic accuracy than SIRS and similar to SOFA in older adults admitted to hospital with community acquired urinary tract infection, having the advantage of not requiring laboratory tests.

RESUMO

Invasive candidiasis (IC) is the most common invasive fungal infection (IFI) affecting critically ill patients, followed by invasive pulmonary aspergillosis (IPA). International guidelines provide different recommendations for a first-line antifungal therapy and, in most of them, echinocandins are considered the first-line treatment for IC, and triazoles are so for the treatment of IPA. However, liposomal amphotericinB (L-AmB) is still considered a second-line therapy for both clinical entities. Although in the last decade the management of IFI has improved, several controversies persist. The antifungal drugs currently available may have a suboptimal activity, or be wrongly used in certain IFI involving critically ill patients. The aim of this review is to analyze when to provide individualized antifungal therapy to critically ill patients suffering from IFI, emphasizing the role of L-AmB. Drug-drug interactions, the clinical status, infectious foci (peritoneal candidiasis is discussed), the fungal species involved, and the need of monitoring the concentration of the antifungal drug in the patient are considered.

RESUMO

In accordance with the recommendations of, amongst others, the Surviving Sepsis Campaign and the recently published European treatment guidelines for hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), in the event of a patient with such infections, empirical antibiotic treatment must be appropriate and administered as early as possible. The aim of this manuscript is to update treatment protocols by reviewing recently published studies on the treatment of nosocomial pneumonia in the critically ill patients that require invasive respiratory support and patients with HAP from hospital wards that require invasive mechanical ventilation. An interdisciplinary group of experts, comprising specialists in anaesthesia and resuscitation and in intensive care medicine, updated the epidemiology and antimicrobial resistance and established clinical management priorities based on patients' risk factors. Implementation of rapid diagnostic microbiological techniques available and the new antibiotics recently added to the therapeutic arsenal has been reviewed and updated. After analysis of the categories outlined, some recommendations were suggested, and an algorithm to update empirical and targeted treatment in critically ill patients has also been designed. These aspects are key to improve VAP outcomes because of the severity of patients and possible acquisition of multidrug-resistant organisms (MDROs).

RESUMO

Spain has been one of the most affected countries by the COVID-19 outbreak. As of April 28, 2020, the number of confirmed cases is 210 773, including 102 548 patients recovered, more than 10 300 admitted to the ICU, and 23 822 deaths, with a global case fatality rate of 11.3%. From the perspective of donation and transplantation, the Spanish system first focused on safety issues, providing recommendations for donor evaluation and testing, and to rule out SARS-CoV-2 infection in potential recipients prior to transplantation. Since the country entered into an epidemiological scenario of sustained community transmission and saturation of intensive care, developing donation and transplantation procedures has become highly complex. Since the national state of alarm was declared in Spain on March 13, 2020, the mean number of donors has declined from 7.2 to 1.2 per day, and the mean number of transplants from 16.1 to 2.1 per day. Increased mortality on the waiting list may become a collateral damage of this terrible pandemic.

RESUMO

The aim was to provide global experts ranking on priorities in diagnostic tools for VAP in clinical practice. A multiple criteria decision analysis (MCDA) was performed to identify diagnosis tools for VAP diagnosis. Priority factors were identified after literature review. An international, multidisciplinary expert panel reviewed variables and ranked diagnostic tools. Experts from ten European hospitals participated. Regarding bedside clinical practices, seven required chest X-ray use in all patients, whereas six reported the use of blood cultures and endotracheal aspirate in all patients. Invasive techniques were routinely performed in seven sites. CRP, PCT, and Gram stains were performed in all patients by 5, 2, and 8, respectively. Impact on patient outcomes, safety, and impact on the decision to start antibiotic therapy were ranked as the top three relevant concerns (7.7/10, 7/10, and 6.9/10, respectively). Chest X-ray was ranked as the most important imaging technique to diagnose VAP (score 251.7). Apart from blood cultures, endotracheal aspirate culture was identified as the main collection method for the microbiological testing (scores of 274.8 and 246.8, respectively). Mini-BAL was the preferred invasive technique with a score of 208. Top three biomarkers were CRP (score 184.3), PCT (181.3), and WBC (166.4). Gram stain (192.5) was prioritized among laboratory diagnostic techniques. Using MCDA, it is recommended to perform a combination of diagnostic techniques including images (chest X-ray), culture of clinical specimens (blood cultures and endotracheal aspirate), and biomarkers (CRP or PCT) for VAP diagnosis at the bedside. Gram stain was ranked as the preferred laboratory technique.

RESUMO

A narrative review from a multidisciplinary task force of experts in critical care medicine and clinical mycology was carried out. The multi drug-resistant species Candida auris has emerged simultaneously on several continents, causing hospital outbreaks, especially in critically ill patients. Although there are not enough data to support the routine use of continuous antibiotic prophylaxis in patients subjected to extracorporeal membrane oxygenator, a clear increase of invasive fungal infection (IFI) has been described with the use of this device. Possible IFI treatment failures could be related with suboptimal antifungal concentrations despite dose adjustment. Invasive aspergillosis has become an important life-threating infection in intensive care unit related with new risk factors described. IFI remain important problem in critical patients due to the appearance of new risk factors, new species, and resistance increase. Multidisciplinary packages of measures designed to reduce IFI incidence and improve diagnostics tools may reduce the high mortality associated.

RESUMO

BACKGROUND: Early appropriate antibiotic treatment is essential in sepsis. We aimed to evaluate the impact of a multifaceted educational intervention to improve antibiotic treatment. We hypothesized that the intervention would hasten and improve the appropriateness of empirical antibiotic administration, favor de-escalation, and decrease mortality. METHODS: We prospectively studied all consecutive patients with sepsis/septic shock admitted to 72 intensive care units (ICUs) throughout Spain in two 4-month periods (before and immediately after the 3-month intervention). We compared process-of-care variables (resuscitation bundle and time-to-initiation, appropriateness, and de-escalation of empirical antibiotic treatment) and outcome variables between the two cohorts. The primary outcome was hospital mortality. We analyzed the intervention's long-term impact in a subset of 50 ICUs. RESULTS: We included 2628 patients (age 64.1 ± 15.2 years; men 64.0%; Acute Physiology and Chronic Health Evaluation (APACHE) II, 22.0 ± 8.1): 1352 in the preintervention cohort and 1276 in the postintervention cohort. In the postintervention cohort, the mean (SD) time from sepsis onset to empirical antibiotic therapy was lower (2.0 (2.7) vs. 2.5 (3.6) h; p = 0.002), the proportion of inappropriate empirical treatments was lower (6.5% vs. 8.9%; p = 0.024), and the proportion of patients in whom antibiotic treatment was de-escalated was higher (20.1% vs. 16.3%; p = 0.004); the expected reduction in mortality did not reach statistical significance (29.4% in the postintervention cohort vs. 30.5% in the preintervention cohort; p = 0.544). Gains observed after the intervention were maintained in the long-term follow-up period. CONCLUSIONS: Despite advances in sepsis treatment, educational interventions can still improve the delivery of care; further improvements might also improve outcomes.

RESUMO

Pseudomonas aeruginosa is characterized by a notable intrinsic resistance to antibiotics, mainly mediated by the expression of inducible chromosomic β-lactamases and the production of constitutive or inducible efflux pumps. Apart from this intrinsic resistance, P. aeruginosa possess an extraordinary ability to develop resistance to nearly all available antimicrobials through selection of mutations. The progressive increase in resistance rates in P. aeruginosa has led to the emergence of strains which, based on their degree of resistance to common antibiotics, have been defined as multidrug resistant, extended-resistant and panresistant strains. These strains are increasingly disseminated worldwide, progressively complicating the treatment of P. aeruginosa infections. In this scenario, the objective of the present guidelines was to review and update published evidence for the treatment of patients with acute, invasive and severe infections caused by P. aeruginosa. To this end, mechanisms of intrinsic resistance, factors favoring development of resistance during antibiotic exposure, prevalence of resistance in Spain, classical and recently appeared new antibiotics active against P. aeruginosa, pharmacodynamic principles predicting efficacy, clinical experience with monotherapy and combination therapy, and principles for antibiotic treatment were reviewed to elaborate recommendations by the panel of experts for empirical and directed treatment of P. aeruginosa invasive infections (AU)


Pseudomonas aeruginosa se caracteriza por una notable resistencia intrínseca a los antibióticos mediada fundamentalmente por la expresión de β-lactamasas cromosómicas inducibles y la producción constitutiva o inducible de bombas de expulsión. Además de esta resistencia intrínseca, P. aeruginosa posee una extraordinaria capacidad para desarrollar resistencia a prácticamente todos los antimicrobianos disponibles a través de la selección de mutaciones. El aumento progresivo de la resistencia en P. aeruginosa ha llevado a la aparición de cepas que, de acuerdo con el grado de resistencia frente a los antibióticos habituales, se han definido como multirresistentes, extensamente resistentes y panresistentes. Estas cepas se están diseminando mundialmente, complicando progresivamente el tratamiento de las infecciones por P. aeruginosa. En este escenario, el objetivo de las presentes recomendaciones es la revisión y puesta al día de la evidencia publicada para el tratamiento de pacientes con infección aguda, invasiva y grave por P. aeruginosa. Con este fin, se han revisado los mecanismos de resistencia intrínseca, factores que favorecen el desarrollo de resistencia durante la exposición a antibióticos, prevalencia de la resistencia en España, antibióticos clásicos así como los de reciente introducción activos frente a P. aeruginosa, principios farmacodinámicos predictores de eficacia, experiencia clínica con tratamientos en monoterapia o terapia combinada y principios del tratamiento antibiótico para elaborar por un panel de xpertos recomendaciones para el tratamiento empírico o dirigido de infecciones invasivas por P. aeruginosa (AU)

RESUMO

Background. Although the management of the invasive candidiasis has improved in the last decade, controversial issues yet remain, especially in the diagnostic and therapeutic approaches to Candida peritonitis and other forms of intra-abdominal fungal infections. Aims. We sought to identify core clinical knowledge about intra-abdominal fungal infections and to achieve high-agreement recommendations required to care for critically ill adult patients with Candida peritonitis and other forms of intra-abdominal fungal infection. Methods. A biregional Spanish survey, to elucidate the consensus about the already mentioned fungal infections by means of the Delphi technique, was conducted anonymously by e-mail with 29 multidisciplinary experts in invasive fungal infections from 14 hospitals in the Valencia and Murcia communities during 2014. Respondents included intensivists, anesthesiologists, microbiologists, pharmacologists, and infectious disease specialists, who answered 31 questions prepared by a coordination group after a strict review of the literature from the 5 previous years. The educational objectives spanned 6 categories: epidemiology, microbiological diagnosis, clinical diagnosis, antifungal treatment, de-escalation therapy, and special situations. The agreement required among the panelists for each item to be selected had to be higher than 70%. After extracting the recommendations from the selected items, a meeting at which the experts were asked to validate the previously selected recommendations in a second round of scoring took place. Results. After the second round, 36 recommendations were validated according to the following distribution: epidemiology (5), microbiological diagnosis (4), clinical diagnosis (4), antifungal treatment (3), de-escalation therapy (4), and special situations (16). Conclusions. Treatment of Candida peritonitis and other forms of intra-abdominal fungal infections in ICU patients requires a broad range of knowledge application and skills that our recommendations address. Based on the DELPHI methodology, these recommendations might help to optimize the therapeutic management of these patients in special situations and in various scenarios to improve their outcome (AU)


Antecedentes. Aunque en la última década se ha observado una mejoría en el manejo de la candidiasis invasora todavía existe controversia, especialmente en la aproximación diagnóstico-terapéutica de la candidiasis peritoneal y otras formas de infección fúngica invasora intraabdominal en el paciente crítico no neutropénico. Objetivos. Identificar los principales conocimientos clínicos sobre las infecciones fúngicas intraabdominales y elaborar recomendaciones con un alto nivel de consenso, necesarias para el diagnóstico y el tratamiento de la candidiasis peritoneal y otras infecciones fúngicas intraabdominales en pacientes adultos críticos no neutropénicos. Métodos. Se realizó un cuestionario prospectivo en dos comunidades autónomas para estimar mediante la técnica Delphi el consenso en el diagnóstico y tratamiento de las infecciones mencionadas. El cuestionario se realizó en el año 2014, de forma anónima y por correo electrónico, con 29 expertos de varias disciplinas, especialistas en infecciones fúngicas invasivas de 14 hospitales de la Comunidad Valenciana y Murciana, entre los que se incluían intensivistas, anestesistas, microbiólogos, farmacéuticos y especialistas en enfermedades infecciosas, que respondieron a 31 preguntas preparadas por el grupo de coordinación, tras una revisión exhaustiva de la literatura de los 5 años previos. Los objetivos educativos contemplaron 6 categorías que incluían epidemiología, diagnóstico microbiológico, diagnóstico clínico, tratamiento antifúngico, desescalado del tratamiento farmacológico y situaciones especiales. El nivel de acuerdo alcanzado entre los expertos en cada una de las categorías debía superar el 75% para ser seleccionada. En un segundo término, después de extraer las recomendaciones de los temas seleccionados, se celebró una reunión presencial con 29 especialistas y se les solicitó la validación de las recomendaciones preseleccionadas. Resultados. Después de la segunda ronda, 36 recomendaciones fueron validadas siguiendo la siguiente distribución: epidemiología (5), diagnóstico microbiológico (4), diagnóstico clínico (4), tratamiento antifúngico, (3), desescalado (4) y situaciones especiales (16). Conclusiones. El manejo de la peritonitis candidiásica en pacientes de UCI requiere la aplicación de los conocimientos y destrezas que se detallan en nuestras recomendaciones. Estas recomendaciones, basadas en la metodología DELPHI, ayudan a optimizar el tratamiento de los pacientes críticos con candidiasis invasiva en distintos escenarios y situaciones clínicas y a mejorar su pronóstico (AU)

RESUMO

Background. A high quality integrated process in the clinical setting of non-neutropenic critically ill patients at risk for invasive candidiasis is a necessary tool to improve the management of these patients. Aims. To identify the key points on invasive candidiasis in order to develop a set of recommendations with a high level of consensus required for the creation of a total quality integrated process for the management of non-neutropenic critically ill patients at risk of invasive candidiasis. Methods. After a thorough review of the literature of the previous five years, a Spanish prospective questionnaire, which measured consensus by the Delphi technique, was anonymously conducted by e-mail, including 31 national multidisciplinary experts with extensive experience in invasive fungal infections, from six national scientific societies. The experts included a specialist in intensive care medicine, anesthetists, microbiologists, pharmacologists, and specialists in infectious diseases that responded 27 questions prepared by the coordination group. The educational objectives considered six processes that included knowledge of the local epidemiology, the creation and development of multidisciplinary teams, the definitions of the process, protocols, and indicators (KPI), an educational phase, hospital implementation, and the measurement of outcomes. The level of agreement among experts in each category to be selected should exceed 70%. In a second phase, after drawing up the recommendations of the selected processes, a face to face meeting with more than 60 specialists was held. The specialists were asked to validate the pre-selected recommendations. Measures and main outcomes. Firstly, 20 recommendations from all the sections were pre-selected: Knowledge of local epidemiology (3 recommendations), creation and development of multidisciplinary teams (3), definition of the process, protocols and indicators (1), educational phase (3), hospital implementation (3), and measurement of outcomes (7). After the second phase, 18 recommendations were validated, and it was concluded that the minimum team or core necessary for the development of an efficient program in the use of antifungal drugs in non-neutropenic critically ill patients must consist of a specialist in infectious diseases, a clinical pharmacist, a microbiologist, a specialist in intensive care medicine, a specialist in anesthesia and recovery, and an administrator or member of the medical management team, and, in order to be cost-effective, it should be implemented in hospitals with over 200 beds. In addition, it is recommended to apply a consensual check list for the evaluation of the diagnostic process and treatment of invasive candidiasis in patients that have started an antifungal treatment. The management of external knowledge and individual learning stand out as active educational strategies. The main strategies for measuring patient safety outcomes are the analysis of the results achieved, and learning activities; assess, review and refine the deployment of the processes; quality control; epidemiological surveillance and applied research; benchmarking; and basic research. The results of the integrated process should be annually disseminated outside the hospital. Conclusions. Optimizing the management of invasive candidiasis requires the application of the knowledge and skills detailed in our recommendations. These recommendations, based on the Delphi methodology, facilitate the creation of a total quality integrated process in critically-ill patients at risk for invasive candidiasis (AU)


Antecedentes. El adecuado manejo de los pacientes críticos no neutropénicos en situación de riesgo de contraer una candidiasis invasiva requiere la implementación de protocolos de alta calidad en la actuación clínica. Objetivos. Identificar los principales conocimientos y elaborar recomendaciones con un alto nivel de consenso, necesarios para la creación de un proceso integrado de calidad total para el manejo del paciente crítico no neutropénico con riesgo de candidiasis invasiva. Métodos. Se realizó un cuestionario prospectivo que mide el grado de consenso mediante la técnica Delphi, de forma anónima y por correo electrónico, entre 31 expertos multidisciplinarios, especialistas en infecciones fúngicas invasivas de seis sociedades científicas, que incluyen intensivistas, anestesistas, microbiólogos, farmacólogos y especialistas en enfermedades infecciosas que respondieron a 27 preguntas preparadas por el grupo de coordinación, tras una revisión exhaustiva de la literatura de los últimos cinco años. Los objetivos educativos contemplaron seis procesos, que incluían el conocimiento de la epidemiología local, la creación y el desarrollo de equipos multidisciplinares, la definición de proceso, protocolos e indicadores (KPI), una fase educacional, la implementación hospitalaria y la medición de resultados. El grado de acuerdo alcanzado entre los expertos en cada una de las categorías debía superar el 70% para ser seleccionada. Después de extraer las recomendaciones de los procesos escogidos, se celebró una reunión presencial con más de 60 especialistas y se les solicitó la validación de las recomendaciones preseleccionadas. Medidas y resultados principales. En un primer término se realizó una preselección de 20 recomendaciones de los siguientes apartados: Conocimiento de la epidemiología local (3), Creación y desarrollo de equipos multidisciplinares (3), Definición de proceso, protocolos e indicadores (1), Fase educacional (3), Implementación hospitalaria (3), Medición de resultados (7). Después de la segunda ronda se validaron 18 recomendaciones que se resumen en que el equipo mínimo (núcleo) necesario para un programa eficiente en el uso de fármacos antifúngicos para el paciente crítico no neutropénico debe estar integrado por un especialista en enfermedades infecciosas, un farmacéutico, un microbiólogo, un especialista en medicina intensiva, un especialista en anestesia y reanimación y un gestor o miembro de la dirección médica. Debería implementarse en hospitales de más de 200 camas para ser coste-efectivo. Además, se recomienda aplicar una lista de comprobación consensuada para la evaluación del proceso de diagnóstico y tratamiento de la candidiasis invasiva en los pacientes en los que se inicie un tratamiento antifúngico. Se destacan como estrategias de educación activa la gestión del conocimiento externo y del aprendizaje individual. Las principales estrategias para medir los resultados de seguridad del paciente son el análisis de los resultados obtenidos que comprenden la comprobación y revisión del proceso, control de calidad, vigilancia epidemiológica, benchmarking e investigación básica. Los resultados del proceso integrado deberían difundirse anualmente fuera del hospital. Conclusiones. La optimización del manejo de la candidiasis invasiva requiere de la aplicación de los conocimientos y destrezas que se detallan en nuestras recomendaciones. Estas recomendaciones basadas en la metodología Delphi, facilitan la creación de un proceso integrado de manejo con calidad total del paciente crítico con riesgo de candidiasis invasiva (AU)
