Nosocomial pneumonia in 27 ICUs in Europe: perspectives from the EU-VAP/CAP study.

We report on intensive care nosocomial pneumonia (NP) in Europe through a review of EU-VAP/CAP manuscripts: a prospective observational study, enrolling patients from 27 ICUs in nine European countries. From 2,436 eligible ICU patients, 827 cases presented NP, with 18.3 episodes of VAP per 1000 ventilator-days. Most common findings were worsening oxygenation, purulent respiratory secretions and temperature increase. At least three criteria from Clinical Pulmonary Infection score (CPIS) were present in 77.9 % of episodes, but only 0.2 % met six CPIS criteria. Diagnosis was confirmed mainly noninvasively (74.8 %), with half qualitative and quantitative cultures. The dominant isolate was S. aureus in Spain, France, Belgium and Ireland, P. aeruginosa in Italy and Portugal, Acinetobacter in Greece and Turkey, but Escherichia coli in Germany. NP resulted in 6 % higher mortality, longer ICU stay and duration of mechanical ventilation (12 and 10 days). COPD and age ≥45 years were not associated with higher VAP incidence but did correlate with increased mortality. Trauma had higher VAP incidence but lower mortality. Bacteremia (led by MRSA and Acinetobacter baumannii) was documented in 14.6 %, being associated with extra ICU stay and mortality. Vasopressors and ICUs with above 25 % prevalence of Potential Resistant Organisms (PRM) were independently associated with PRM, being documented in 50.7 % of patients with early-onset VAP without known risk factors. Most patients initially received combination therapy. Delay in appropriate antimicrobial choice significantly increased mortality, and LOS in survivors was six days longer (p < 0.05). In conclusion, NP management in Europe presents local differences and major shifts when compared to reports from North America, outcomes of randomized trials and general guidelines.

Infections in intensive care unit adult patients harboring multidrug-resistant Pseudomonas aeruginosa: implications for prevention and therapy.

The purpose of this paper was to report the burden and characteristics of infection by multidrug-resistant Pseudomonas aeruginosa (MDR-PA) in clinical samples from intensive care unit (ICU) adults, and to identify predictors. This was a retrospective observational study at four medical-surgical ICUs. The case cohort comprised adults with documented isolation of an MDR-PA strain from a clinical specimen during ICU stay. Multivariate analysis was performed to identify predictors for MDR-PA infection. During the study period, 5667 patients were admitted to the ICU and P. aeruginosa was isolated in 504 (8.8%). MDR-PA was identified in 142 clinical samples from 104 patients (20.6%); 62 (43.6%) of these samples appeared to be true infections. One hundred and eighteen (83.1%) isolates were susceptible only to amikacin and colistin, and 13 (9.2%) were susceptible only to colistin. Overall, the MIC50 to meropenem was 16 µg/mL and the MIC90 was >32 µg/mL, with 60.4% of respiratory samples being MIC >32 µg/mL to meropenem. Independent predictors for MDR-PA infection were fever/hypothermia [odds ratio (OR) 9.09], recent antipseudomonal cephalosporin therapy (OR 6.31), vasopressors at infection onset (OR 4.40), and PIRO (predisposition, infection, response, and organ dysfunction) score >2 (OR 2.06). This study provides novel information that may be of use for the clinical management of patients harboring MDR-PA and for the control of the spread of this organism.

The clinical significance of pneumonia in patients with respiratory specimens harbouring multidrug-resistant Pseudomonas aeruginosa: a 5-year retrospective study following 5667 patients in four general ICUs.

Pseudomonas aeruginosa is the leading cause of pneumonia in intensive care units (ICUs), with multidrug-resistant (MDR) strains posing a serious threat. The aim of this study was to assess the clinical relevance of MDR Pseudomonas isolates in respiratory clinical specimens. A 5-year retrospective observational study in four medical-surgical ICUs from a referral hospital was carried out. Of 5667 adults admitted to the ICU, 69 had MDR-PA in respiratory samples: 31 were identified as having pneumonia (HAP/VAP): 21 ventilator-associated pneumonia (VAP) and ten hospital-acquired pneumonia (HAP). Twenty-one (67.7%) adults with MDR-PA HAP/VAP died after a median of 4 days (18 of the 21 deaths within 8 days), compared with one (2.6%) without pneumonia at day 8. In a Cox proportional regression model, MDR-PA pneumonia was an independent variable [adjusted hazard ratio (aHR) 5.92] associated with 30-day ICU mortality. Most strains (85.1%) were susceptible to amikacin and colistin. Resistance to beta-lactams (third-generation cephalosporins and piperacillin-tazobactam) ranged from 44.1% to 45.3%. Meropenem showed poor overall activity (MIC[50/90] 16/32 mg/dL), with 47.0% having a minimum inhibitory concentration (MIC) breakpoint >8 mg/L. Twenty-four (77.4%) HAP/VAP episodes received inappropriate empirical therapy. Although empirical combination therapy was associated with less inappropriate therapy than monotherapy (16.7% vs. 88.3%, p < 0.01), there was no difference in survival (30% vs. 33.3%, p = 0.8). Pneumonia was identified in one-third of adult ICU patients harbouring MDR-PA in respiratory clinical specimens. These patients have a 6-fold risk of (early) death compared to ventilator-associated tracheobronchitis (VAT) and respiratory colonisation. New antibiotics and adjuvant therapies are urgently needed to prevent and treat MDR-PA HAP/VAP.

Improved survival among ICU-hospitalized patients with community-acquired pneumonia by unidentified organisms: a multicenter case-control study.

A retrospective analysis from prospectively collected data was conducted in intensive care units (ICUs) at 33 hospitals in Europe comparing the trend in ICU survival among adults with severe community-acquired pneumonia (CAP) due to unknown organisms from 2000 to 2015. The secondary objective was to establish whether changes in antibiotic policies were associated with different outcomes. ICU mortality decreased (p = 0.02) from 26.9 % in the first study period (2000-2002) to 15.7 % in the second period (2008-2015). Demographic data and clinical severity at admission were comparable between groups, except for age over 65 years and incidence of cardiomyopathy. Over time, patients received higher rates of combination therapy (94.3 vs. 77.2 %; p < 0.01) and early (<3 h) antibiotic delivery (72.9 vs. 50.3 %; p < 0.01); likewise, the 2008-2015 group was more likely to receive adequate antibiotic prescription [as defined by the Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) guidelines] than the 2000-2002 group (70.7 vs. 48.2 %; p < 0.01). Multivariate analysis showed an independent association between decreased ICU mortality and early (<3 h) antibiotic administration [odds ratio (OR) 3.48 [1.70-7.15], p < 0.01] or adequate antibiotic prescription according to guidelines (OR 2.22 [1.11-4.43], p = 0.02). In conclusion, our findings suggest that ICU mortality in severe CAP due to unidentified organisms has decreased in the last 15 years. Several changes in management and better compliance with guidelines over time were associated with increased survival.

Association between source control and mortality in 258 patients with intra-abdominal candidiasis: a retrospective multi-centric analysis comparing intensive care versus surgical wards in Spain.

Early empiric therapy and adequate resuscitation have been identified as main predictors of outcome in patients with candidemia or bacteremia. Moreover, source control is a major determinant in infectious sites when feasible, as a main technique to reduce microbiological burden. A retrospective, multicenter, cohort study was performed at surgical wards and intensive care units (ICU) of three University Hospitals in Spain between 2010 and 2014, with the aim of improving understanding of the interaction between source control, early antifungal therapy, and use of vasoactives in patients with intra-abdominal candidiasis (IAC). Source control was defined as all physical actions taken to control a focus of infection and reduce the favorable conditions that promote microorganism growth or that maintain the impairment of host defenses. Two hundred and fifty-eight patients with IAC were identified. Sixty-one patients were at ICU for diagnosis. Mortality was higher in the ICU group compared to what was documented for the non-ICU group (35 % vs 19.5 %, p = 0011). Adequate source control within 48 h of diagnosis was achieved in 60 % of the cohort. In multivariate analysis, inadequate source control was identified as the only common risk factor for 30-day mortality in both groups (ICU group OR: 13.78 (95% CI: 2.60-72.9, p = 0.002) and non-ICU group OR: 6.53 (95% CI: 2.56-16.61, p = <0.001). The population receiving both adequate source control and adequate antifungal treatment was the one associated with a higher survival rate, in both the ICU and surgical groups. Source control remains a key element in IAC, inside and outside the intensive care unit. Early antifungal treatment among ICU patients was associated with lower mortality.

Primary Graft Dysfunction and Mortality Following Lung Transplantation: A Role for Proadrenomedullin Plasma Levels.

Primary graft dysfunction (PGD) after lung transplantation (LT) is a heterogeneous syndrome that comprises clinical presentations with diverse grades of severity. Proadrenomedullin (proADM) levels may be associated with PGD and may enhance its relationship with outcomes. We prospectively included 100 LT recipients. Plasma levels of proADM were measured at 24, 48 and 72 h after admission to the intensive care unit (ICU). We assessed their relationship with PGD grade and ICU mortality. Fifty patients (50%) presented grade 3 PGD at ICU admission. Twenty-two patients (22%) developed grade 3 PGD at 72 h, the only grade associated with higher mortality (odds ratio 6.84, 95% confidence interval [CI] 1.47-38.44). ProADM levels measured at 24 h (3.25 vs. 1.61 nmol/L; p = 0.016) and 72 h (2.17 vs. 1.35 nmol/L; p = 0.011) were higher in these patients than the rest of the population. When we added the individual predictive utility of grade 3 PGD at 72 h for ICU mortality (area under the curve [AUC] 0.72, 95% CI 0.53-0.90) to that of ProADM at 72 h, the predictive value of the model improved (AUC 0.81, 95% CI 0.65-0.97). Higher levels of proADM measured following LT are associated with grade 3 PGD at 72 h. ProADM enhances the association of this entity with mortality.

Invasive candidiasis: from mycobiome to infection, therapy, and prevention.

Candida spp. are commonly found in humans, colonizing most healthy individuals. A high prevalence of invasive candidiasis has been reported in recent years. Here, we assess the relation between Candida spp. as part of the human mycobiome, the host defense mechanisms, and the pathophysiology of invasive disease in critically ill patients. Many hypotheses have been proposed to explain the different immune responses to the process where Candida goes through healthy mycobiome to colonization to invasion; the involvement of other microbiota inhabitants, changes in temperature, low nitrogen levels, and the caspase system activation have been described. Patients admitted to an intensive care unit (ICU) are at the highest risk for invasive candidiasis, mostly due to the severity of their disease, immune-suppressive states, prolonged length of stay, broad-spectrum antibiotics, septic shock, and Candida colonization. The first approach should be using predictive scores as screening, followed by the determination of biomarkers (when available), and, in the near future, probably immune-genomics and analysis of the clinical background in order to initiate prompt and correct treatment. Regarding treatment, the initiation with an echinocandin is strongly recommended in critically ill patients. In conclusion, prompt treatment and adequate source control in the more severe patients remains the ultimate goal, as well as restoration of a healthy microbiota.

Management of septic shock and severe infections in migrants and returning travelers requiring critical care.

During the past decade, global human movement created a virtually "borderless world". Consequently, the developed world is facing "forgotten" and now imported infectious diseases. Many infections are observed upon travel and migration, and the clinical spectrum is diverse, ranging from asymptomatic infection to severe septic shock. The severity of infection depends on the etiology and timeliness of diagnosis. While assessing the etiology of severe infection in travelers and migrants, it is important to acquire a detailed clinical history; geography, dates of travel, places visited, type of transportation, lay-overs and intermediate stops, potential exposure to exotic diseases, and activities that were undertaken during travelling and prophylaxis and vaccines either taken or not before travel are all important parameters. Tuberculosis, malaria, pneumonia, visceral leishmaniasis, enteric fever and hemorrhagic fever are the most common etiologies in severely infected travelers and migrants. The management of severe sepsis and septic shock in migrants and returning travelers requires a systematic approach in the evaluation of these patients based on travel history. Early and broad-spectrum therapy is recommended for the management of septic shock comprising broad spectrum antibiotics, source control, fluid therapy and hemodynamic support, corticosteroids, tight glycemic control, and organ support and monitoring. We here review the diagnostic and therapeutic routing of severely ill travelers and migrants, stratified by the nature of the infectious agents most often encountered among them.

Personalized medicine in severe influenza.

Existing therapies against infectious diseases may only be effective in limited subpopulations during specific phases of diseases, incorporating theranostics, and there is a clear need to individualize different therapeutic approaches depending on the host. Influenza A virus infection evolves into a severe respiratory failure in some young adult patients, related to an exaggerated inflammatory response. Mortality rates remain high despite antiviral treatment and aggressive respiratory support. The influenza A virus (IAV) infection will induce a proinflammatory innate immune response through recognition of viral RNA by Toll-like receptor (TLR) 7 and retinoic acid-inducible gene 1 (RIG-I) molecules by nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB route). Anti-inflammatory therapies focused on modulating this inflammatory response to "all patients" have not been satisfactory. Steroids should be avoided because they do not improve survival and promote superinfections. Since clinical judgment has often been proven inadequate, interest in the use of biomarkers to monitor host response and to assess severity and complications is growing. It is well known that, if used appropriately, these can be helpful tools to predict not only severity but also mortality. We need more biomarkers that predict host response: it is time to change lactate measurement to proteomics and transcriptomics. Theranostics describes an approach covering both diagnosis and coupled therapy. Death is usually a fatal complication of a dysregulated immune response more than the acute virulence of the infectious agent. Future research demonstrating the usefulness of adjunctive therapy in a subset of critically ill patients with IAV pneumonia is an unmet clinical need.

Nosocomial pneumonia caused by methicillin-resistant Staphylococcus aureus treated with linezolid or vancomycin: A secondary economic analysis of resource use from a Spanish perspective.

OBJECTIVES: Adopting a unique Spanish perspective, this study aims to assess healthcare resource utilization (HCRU) and the costs of treating nosocomial pneumonia (NP) produced by methicillin-resistant Staphylococcus aureus (MRSA) in hospitalized adults using linezolid or vancomycin. An evaluation is also made of the renal failure rate and related economic outcomes between study groups. DESIGN: An economic post hoc evaluation of a randomized, double-blind, multicenter phase 4 study was carried out. SCOPE: Nosocomial pneumonia due to MRSA in hospitalized adults. PARTICIPANTS: The modified intent to treat (mITT) population comprised 224 linezolid- and 224 vancomycin-treated patients. INTERVENTIONS: Costs and HCRU were evaluated between patients administered either linezolid or vancomycin, and between patients who developed renal failure and those who did not. PRIMARY ENDPOINTS: Analysis of HCRU outcomes and costs. RESULTS: Total costs were similar between the linezolid- (€17,782±€9,615) and vancomycin-treated patients (€17,423±€9,460) (P=.69). The renal failure rate was significantly lower in the linezolid-treated patients (4% vs. 15%; P<.001). The total costs tended to be higher in patients who developed renal failure (€19,626±€10,840 vs. €17,388±€9,369; P=.14). Among the patients who developed renal failure, HCRU (days on mechanical ventilation: 13.2±10.7 vs. 7.6±3.6 days; P=.21; ICU stay: 14.4±10.5 vs. 9.9±6.6 days; P=.30; hospital stay: 19.5±9.5 vs. 16.1±11.0 days; P=.26) and cost (€17,219±€8,792 vs. €20,263±€11,350; P=.51) tended to be lower in the linezolid- vs. vancomycin-treated patients. There were no statistically significant differences in costs per patient-day between cohorts after correcting for mortality (€1000 vs. €1,010; P=.98). CONCLUSIONS: From a Spanish perspective, there were no statistically significant differences in total costs between the linezolid and vancomycin pneumonia cohorts. The drug cost corresponding to linezolid was partially offset by fewer renal failure adverse events.

Impact of influenza season and environmental factors on the clinical presentation and outcome of invasive pneumococcal disease.

Influenza and meteorological factors have been associated with increases in the incidence of invasive pneumococcal disease (IPD). However, scant data regarding the impact of influenza and the environment on the clinical presentation of IPD are available. An observational study of all adults hospitalized with IPD was performed between 1996 and 2012 in our hospital. The incidence of IPD correlated with the incidence rates of influenza and with environmental data. A negative binominal regression was used to assess the relationship between these factors. Clinical presentation of IPD during the influenza and non-influenza periods was compared. During the study, 1,150 episodes of IPD were diagnosed. After adjusting for confounding variables, factors correlating with the rates of IPD were the incidence of influenza infection (IRR 1.229, 95% CI 1.025-1.472) and the average ambient temperature (IRR 0.921, 95% CI 0.88-0.964). Patients with IPD during the influenza period had a worse respiratory status. A greater proportion of patients had respiratory failure (45.6% vs 52%, p = 0.032) and higher requirements for ICU admission (19.3% vs 24.7%, p = 0.018) and mechanical ventilation (11% vs 15.1%, p = 0.038). When we stratified by invasiveness of pneumococcal serotypes and the presence of comorbid conditions, the increase in the severity of clinical presentation was focused on healthy adults with IPD caused by nonhighly invasive serotypes. Beyond the increase in the burden of IPD associated with influenza, a more severe clinical pattern of pneumococcal disease was observed in the influenza period. This effect varied according to pneumococcal serotype, host comorbidities, and age.

COPD patients with ventilator-associated pneumonia: implications for management.

Data on the occurrence and outcome of patients with chronic obstructive pulmonary disease (COPD) and ventilator-associated pneumonia (VAP) are quite limited. The aim of this study was to determine if COPD intensive care unit (ICU) patients have a higher rate of VAP development, different microbiological aetiology or have worse outcomes than other patients without VAP. A secondary analysis of a large prospective, observational study conducted in 27 European ICUs was carried out. Trauma patients were excluded. Of 2082 intubated patients included in the study, 397 (19.1%) had COPD; 79 (19.9%) patients with COPD and 332 (19.7%) patients without COPD developed VAP. ICU mortality increased by 17% (p < 0.05) when COPD patients developed VAP, remaining an independent predictor of mortality [odds ratio (OR) 2.28; 95% confidence interval (CI) 1.35-3.87]. The development of VAP in COPD patients was associated with a median increase of 12 days in the duration of mechanical ventilation and >13 days in ICU stay (p < 0.05). Pseudomonas aeruginosa was more common in VAP when COPD was present (29.1% vs. 18.7%, p = 0.04) and was the most frequent isolate in COPD patients with early-onset VAP, with a frequency 2.5 times higher than in patients without early-onset VAP (33.3% vs. 13.3%, p = 0.03). COPD patients are not more predisposed to VAP than other ICU patients, but if COPD patients develop VAP, they have a worse outcome. Antibiotic coverage for non-fermenters needs to be included in the empiric therapy of all COPD patients, even in early-onset VAP.

Clostridium difficile in the ICU: study of the incidence, recurrence, clinical characteristics and complications in a university hospital.

OBJECTIVE: Although several studies have established the association between antibiotics and Clostridium difficile infection (CDI), there is a lack of epidemiological studies on the incidence of CDI in European Intensive Care Units outside the context of infection outbreaks. The present study describes the incidence, patient characteristics, complications, and recurrence rates of CDI in a Spanish ICU. DESIGN: A retrospective study was carried out. SETTING: A clinical-surgical ICU with 34 beds, a tertiary referral hospital with 1400 beds. PATIENTS: All patients over 18 years of age admitted to the ICU from January 2010 to December 2011 with diarrhea for more than 48 h. INTERVENTIONS: None. STUDY VARIABLES: Underlying diseases, risk factors, fever, leukocyte count, complications, recurrence of infection. RESULTS: A total of 1936 adult patients were admitted. Seven patients acquired CDI (0.36%), representing an infection rate of 3.1 per 10,000 bed-days and a cumulative incidence rate of 3.6 in two years. The mean age was 61 years. Six patients showed some degree of immunosuppression. The mean APACHE II score at ICU admission was 17 (IQR 13-24). Severe sepsis was reported in 5 cases of CDI, three of which presented shock and multiorgan dysfunction. Four patients presented recurrence of CDI during hospitalization. ICU admission was prolonged for a mean of 24 days (SD 17.8) after diagnosis. CONCLUSIONS: Less than 1% of the patients admitted to a clinical-surgical ICU in a large teaching institution in Spain developed CDI. However, a high risk of recurrence/complications was associated with prolonged ICU stay.

[Role of biomarkers in the differential diagnosis of acute respiratory failure in the immediate postoperative period of lung transplantation]. / Papel de los biomarcadores en el diagnóstico diferencial de la insuficiencia respiratoria aguda en el postoperatorio inmediato del trasplante pulmonar.

Lung transplant recipients are at high risk of suffering many complications during the immediate postoperative period, such as primary graft dysfunction, acute graft rejection or infection. The most common symptom is the presence of acute respiratory failure, and the use of biomarkers could be useful for establishing an early diagnosis of these conditions. Different biomarkers have been studied, but none have proven to be the gold standard in the differential diagnosis of acute respiratory failure. This paper offers a review of the different biomarkers that have been studied in this field.

Community-acquired Legionella Pneumonia in the intensive care unit: Impact on survival of combined antibiotic therapy.

OBJECTIVES: To compare intensive care unit (ICU) mortality in patients with severe community-acquired pneumonia (SCAP) caused by Legionella pneumophila receiving combined therapy or monotherapy. METHODS: A prospective multicenter study was made, including all patients with sporadic, community-acquired Legionnaires' disease (LD) admitted to the ICU. Admission data and information on the course of the disease were recorded. Antibiotic prescriptions were left to the discretion of the attending physician and were not standardized. RESULTS: Twenty-five cases of SCAP due to L. pneumophila were included, and 7 patients (28%) out of 25 died after a median of 7 days of mechanical ventilation. Fifteen patients (60%) presented shock. Levofloxacin and clarithromycin were the antibiotics most commonly used in monotherapy, while the most frequent combination was rifampicin plus clarithromycin. Patients subjected to combination therapy presented a lower mortality rate versus patients subjected to monotherapy (odds ratio for death [OR] 0.15; 95%CI 0.02-1.04; p=0.08). In patients with shock, this association was stronger and proved statistically significant (OR for death 0.06; 95%CI 0.004-0.86; p=0.04). CONCLUSIONS: Combined antibiotic therapy decreases mortality in patients with SCAP and shock caused by L. pneumophila.

Differences in hospital- and ventilator-associated pneumonia due to Staphylococcus aureus (methicillin-susceptible and methicillin-resistant) between Europe and Latin America: a comparison of the EUVAP and LATINVAP study cohorts.

PURPOSE: A comparison is made of epidemiological variables (demographic and clinical characteristics) and outcomes in patients with hospital-acquired pneumonia (HAP) or ventilator-associated pneumonia (VAP) caused by methicillin-susceptible and methicillin-resistant Staphylococcus aureus (MSSA and MRSA) in the Latin American VAP (LATINVAP) vs. the European Union VAP (EUVAP) cohorts of patients admitted to intensive care units (ICUs). METHODS: The EUVAP project was a prospective, multicenter observational study reporting 827 patients with HAP/VAP in 27 ICUs from 9 European countries. The LATINVAP project was a multicenter prospective observational study, with an identical design, performed in 17 ICUs from 4 Latin American countries involving 99 patients who developed HAP/VAP. Episodes of VAP/HAP caused by S. aureus, MSSA, and MRSA were compared in both cohorts. RESULTS: Forty-five patients had S. aureus HAP/VAP in the EUVAP cohort vs. 11 patients in the LATINVAP cohort. More patients had MRSA in the LATINVAP study than in the EUVAP (45% vs. 33%). ICU mortality among patients with MSSA HAP/VAP in EUVAP was 10% vs. 50% for LATINVAP (OR=9.75, p=0.01). Fifteen patients in the EUVAP cohort developed MRSA HAP/VAP as opposed to 5 in LATINVAP. In the EUVAP study there was an ICU mortality rate of 33.3%. In the LATINVAP cohort, the ICU mortality rate was 60% (OR for death=3.0; 95%CI 0.24-44.7). CONCLUSION: MRSA pneumonia was associated with poorer outcomes in comparison with MSSA. Our study suggests significant variability among European and Latin American ICU practices that may influence clinical outcomes. Furthermore, patients with pneumonia in Latin America have different outcomes.

[Antifungal prophylaxis in the postoperative period of lung transplant surgery in Spain]. / Profilaxis antifúngica en el postoperatorio de trasplante de pulmón en España.

OBJECTIVES: To examine the type and duration of antifungal prophylaxis provided during the postoperative period of lung transplant recipients, together with the most frequent complications during admission to Intensive Care Units in Spain. PATIENTS AND METHODS: A questionnaire was developed including demographic data on each transplant center, the type of antifungal prophylaxis used, its duration, and the most frequent complications. The questionnaire was distributed among the 7 Spanish national lung transplant centers, followed by analysis of the results obtained. RESULTS: All 7 centers completed the questionnaire. All of them provided universal prophylaxis in lung transplant patients. Monotherapy was the most widely used protocol (5/7; 71.4%), with amphotericin B in liposomal or conventional form being the most frequent drug, administered via the inhalatory route. In the case of combination therapy, a great diversity of drugs was observed. The most frequently administered second choice drug was anidulafungin (3/7; 43%), followed by voriconazole (2/7; 28.5%). Antifungal therapy was maintained on an indefinite basis by 43% of the centers. Invasive fungal infection (IFI) in the postoperative period of transplantation during admission to the Intensive Care Unit was suspected in 5-10% of the cases but was confirmed in less than 5%. Among other complications registered in these patients in the Intensive Care Unit, the most frequent problems were respiratory infections (5/7; 71.5%). CONCLUSIONS: Antifungal prophylaxis during the postoperative period of lung transplantation is provided on a universal basis, though consensus is lacking as to the drug of choice, the administration route and the duration of such treatment.

Initial management of pneumonia and sepsis: factors associated with improved outcome.

Processes of care and adherence to guidelines have been associated with improved survival in community-acquired pneumonia (CAP). In sepsis, bundles of processes of care have also increased survival. We aimed to audit compliance with guideline-recommended processes of care and its impact on outcome in hospitalised CAP patients with sepsis. We prospectively studied 4,137 patients hospitalised with CAP in 13 hospitals. The processes of care evaluated were adherence to antibiotic prescription guidelines, first dose within 6 h and oxygen assessment. Outcome measures were mortality and length of stay (LOS). Oxygen assessment was measured in 3,745 (90.5%) patients; 3,024 (73.1%) patients received antibiotics according to guidelines and 3,053 (73.8%) received antibiotics within 6 h. In CAP patients with sepsis, the strongest independent factor for survival was antibiotic adherence (OR 0.4). In severe sepsis, only compliance to antibiotic adherence plus first dose within 6 h was associated with lower mortality (OR 0.60), adjusted for fine prognostic scale and hospital. Antibiotic adherence was related to shorter hospital stay. In sepsis, antibiotic adherence is the strongest protective factor of care associated with survival and LOS. In severe sepsis, combined antibiotic adherence and first dose within 6 h may reduce mortality.
