Abstract
INTRODUCTION The 2007 IDSA/ATS guidelines for community-acquired pneumonia (CAP) recommended intensive care unit (ICU) admission for adults meeting severe CAP criteria. We aimed to validate the accuracy of IDSA/ATS criteria in patients≥80 years old (very elderly patients, VEP) with CAP. METHODS Prospective cohort study of VEP with CAP admitted to three Spanish hospitals between 1996 and 2019. We compared patients who did and did not require ICU admission. We also assessed factors independently associated with ICU admission, as well as the accuracy of severe CAP criteria for ICU admission and mortality. Major criteria include septic shock and invasive mechanical ventilation while minor criteria encompass other variables related to hemodynamics and respiratory insufficiency as well as level of consciousness, renal function, blood parameters indicative of sepsis and body temperature. RESULTS Of the 2006 VEP with CAP, 519 (26%) met severe CAP criteria, while 204 (10%) required ICU admission. Concordance between severe CAP criteria and the decision to admit the patient to the ICU occurred in 1591 (79%) cases (k coefficient, 0.33), with a sensitivity of 75% and specificity of 80% in predicting ICU admission. All patients with invasive mechanical ventilation received care in ICUs, while 45 (44%) patients with septic shock-previously stabilized in the emergency room-did not. Thirty-day mortality of ICU-admitted patients with septic shock was lower than that of patients in wards (30% vs. 60%, p=0.013). In contrast, patients with severe CAP and only minor criteria had similar mortality. CONCLUSIONS IDSA/ATS criteria for severe CAP predict ICU admission in VEP moderately well. While patients with septic shock and invasive mechanical ventilation warrant ICU admission, severe CAP without major severity criteria in VEP may be acceptably manageable in wards.

Comparison between the Severity Scoring Systems A-DROP and CURB-65 for Predicting Safe Discharge from the Emergency Department in Patients with Community-Acquired Pneumonia. Emerg Med Int 2022; 2022:6391141. [PMID: 35480967 PMCID: PMC9038425 DOI: 10.1155/2022/6391141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 02/12/2022] [Accepted: 03/14/2022] [Indexed: 12/02/2022] Open
Abstract
Background In most community-acquired pneumonia (CAP) treatment guidelines, the Pneumonia Severity Index (PSI) and CURB-65 are used as prognostic tools. Recently, simpler and more effective predictive tools for CAP treatment, such as the A-DROP scoring system, have been developed. However, no study has performed a comparative evaluation to identify the superior tool for predicting when patients can be discharged safely. Objectives To compare the performances of A-DROP and CURB-65, simple predictive tools for CAP, based on 30-day death rates and 72-hour revisit rates for CAP following discharge from the emergency department (ED). Method This single-center retrospective observational study enrolled patients who were at least 18 years old and diagnosed with CAP at the Songklanagarind Hospital ED from January 2015 to April 2021. Following a severity assessment using the A-DROP and CURB-65 scoring systems, the 30-day mortality rates and 72-hour revisit rates after discharge from the ED were compared. Results A total of 408 patients were enrolled in this study. Six (1.47%) died within 30 days after presentation, whereas 29 (7.1%) returned to the ED within 72 hours after discharge. Most patients (72%) who revisited the ED were over the age of 65 years. The areas under the receiver operating characteristic curves for the prediction of 30-day mortality were 0.756 (95% confidence interval [CI]: 0.526–0.987) and 0.808 (95% CI: 0.647–0.970) for A-DROP and CURB-65, respectively. The areas under the receiver operating characteristic curves for the prediction of 72-hour revisit were 0.617 (95% confidence interval [CI]: 0.507–0.728) and 0.639 (95% CI: 0.536–0.743) for A-DROP and CURB-65, respectively. Conclusion A-DROP and CURB-65 yield similar results and can be used to assess low-risk patients with CAP for discharge from the ED. Older patients, even those with low-risk scores, should be particularly considered for admission to a short-term observation unit or ward.

A prediction rule for severe adverse events in all inpatients with community-acquired pneumonia: a multicenter observational study. BMC Pulm Med 2022; 22:34. [PMID: 35022026 PMCID: PMC8753951 DOI: 10.1186/s12890-022-01819-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 12/29/2021] [Indexed: 11/23/2022] Open
Abstract
Background Prediction of inpatients with community-acquired pneumonia (CAP) at high risk for severe adverse events (SAEs) requiring higher-intensity treatment is critical. However, evidence regarding prediction rules applicable to all patients with CAP including those with healthcare-associated pneumonia (HCAP) is limited. The objective of this study is to develop and validate a new prediction system for SAEs in inpatients with CAP. Methods Logistic regression analysis was performed in 1334 inpatients of a prospective multicenter study to develop a multivariate model predicting SAEs (death, requirement of mechanical ventilation, and vasopressor support within 30 days after diagnosis). The developed ALL-COP-SCORE rule based on the multivariate model was validated in 643 inpatients in another prospective multicenter study. Results The ALL-COP SCORE rule included albumin (< 2 g/dL, 2 points; 2–3 g/dL, 1 point), white blood cell (< 4000 cells/μL, 3 points), chronic lung disease (1 point), confusion (2 points), PaO2/FIO2 ratio (< 200 mmHg, 3 points; 200–300 mmHg, 1 point), potassium (≥ 5.0 mEq/L, 2 points), arterial pH (< 7.35, 2 points), systolic blood pressure (< 90 mmHg, 2 points), PaCO2 (> 45 mmHg, 2 points), HCO3− (< 20 mmol/L, 1 point), respiratory rate (≥ 30 breaths/min, 1 point), pleural effusion (1 point), and extent of chest radiographical infiltration in unilateral lung (> 2/3, 2 points; 1/2–2/3, 1 point). Patients with 4–5, 6–7, and ≥ 8 points had 17%, 35%, and 52% increase in the probability of SAEs, respectively, whereas the probability of SAEs was 3% in patients with ≤ 3 points. The ALL-COP SCORE rule exhibited a higher area under the receiver operating characteristic curve (0.85) compared with the other predictive models, and an ALL-COP SCORE threshold of ≥ 4 points exhibited 92% sensitivity and 60% specificity. Conclusions ALL-COP SCORE rule can be useful to predict SAEs and aid in decision-making on treatment intensity for all inpatients with CAP including those with HCAP. Higher-intensity treatment should be considered in patients with CAP and an ALL-COP SCORE threshold of ≥ 4 points.

Significance of the Modified NUTRIC Score for Predicting Clinical Outcomes in Patients with Severe Community-Acquired Pneumonia. Nutrients 2021; 14:nu14010198. [PMID: 35011073 PMCID: PMC8747298 DOI: 10.3390/nu14010198] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 12/26/2021] [Accepted: 12/29/2021] [Indexed: 12/12/2022] Open
Abstract
Nutritional status could affect clinical outcomes in critical patients. We aimed to determine the prognostic accuracy of the modified Nutrition Risk in Critically Ill (mNUTRIC) score for hospital mortality and treatment outcomes in patients with severe community-acquired pneumonia (SCAP) compared to other clinical prediction rules. We enrolled SCAP patients in a multi-center setting retrospectively. The mNUTRIC score and clinical prediction rules for pneumonia, as well as clinical factors, were calculated and recorded. Clinical outcomes, including mortality status and treatment outcome, were assessed after the patient was discharged. We used the receiver operating characteristic (ROC) curve method and multivariate logistic regression analysis to determine the prognostic accuracy of the mNUTRIC score for predicting clinical outcomes compared to clinical prediction rules, while 815 SCAP patients were enrolled. ROC curve analysis showed that the mNUTRIC score was the most effective at predicting each clinical outcome and had the highest area under the ROC curve value. The cut-off value for predicting clinical outcomes was 5.5. By multivariate logistic regression analysis, the mNUTRIC score was also an independent predictor of both clinical outcomes in SCAP patients. We concluded that the mNUTRIC score is a better prognostic factor for predicting clinical outcomes in SCAP patients compared to other clinical prediction rules.

Association between delay in intensive care unit admission and the host response in patients with community-acquired pneumonia. Ann Intensive Care 2021; 11:142. [PMID: 34585271 PMCID: PMC8478267 DOI: 10.1186/s13613-021-00930-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 09/20/2021] [Indexed: 12/12/2022] Open
Abstract
Background A delay in admission to the intensive care unit (ICU) of patients with community-acquired pneumonia (CAP) has been associated with an increased mortality. Decisions regarding interventions and eligibility for immune modulatory therapy are often made at the time of admission to the ICU. The primary aim of this study was to compare the host immune response measured upon ICU admission in CAP patients admitted immediately from the emergency department (direct ICU admission) with those who were transferred within 72 h after admission to the general ward (delayed ICU admission). Methods Sixteen host response biomarkers providing insight in pathophysiological mechanisms implicated in sepsis and blood leukocyte transcriptomes were analysed in patients with CAP upon ICU admission in two tertiary hospitals in the Netherlands. Results Of 530 ICU admissions with CAP, 387 (73.0%) were directly admitted and 143 (27.0%) had a delayed admission. Patients with a delayed ICU admission were more often immunocompromised (35.0 versus 21.2%, P = .002) and had more malignancies (23.1 versus 13.4%, P = .011). Shock was more present in patients who were admitted to the ICU directly (46.6 versus 33.6%, P = .010). Delayed ICU admission was not associated with an increased hospital mortality risk (hazard ratio 1.25, 95% CI 0.89–1.78, P = .20). The plasma levels of biomarkers (n = 297) reflecting systemic inflammation, endothelial cell activation and coagulation activation were largely similar between groups, with exception of C-reactive protein, soluble intercellular adhesion molecule-1 and angiopoietin-1, which were more aberrant in delayed admissions compared to direct ICU admissions. Blood leukocyte transcriptomes (n = 132) of patients with a delayed ICU admission showed blunted innate and adaptive immune response signalling when compared with direct ICU admissions, as well as decreased gene expression associated with tissue repair and extracellular matrix remodelling pathways. Conclusions Blood leukocytes of CAP patients with delayed ICU admission show evidence of a more immune suppressive phenotype upon ICU admission when compared with blood leukocytes from patients directly transferred to the ICU.

Abstract
Background Although numerous studies have investigated obesity's negative effect on coronavirus disease 2019 (COVID-19) outcomes, only a limited number focused on this association in diabetic patients. In this study, we analyzed the association between obesity and COVID-19 outcome (death, intensive care unit [ICU] admission, mechanical ventilation needs, quick Sequential Organ Failure Assessment [qSOFA] score, and confusion, urea, respiratory rate, blood pressure [CURB-65] scores) for hospitalized diabetic patients. Methods In this prospective hospital-based registry of patients with COVID-19 in East Azerbaijan, Iran, 368 consecutive diabetic patients with COVID-19 were followed from admission until discharge or death. Self-reported weight and height were used to calculate body mass index (kg/m2) upon admission. Our primary endpoint was analyzing obesity and COVID-19 mortality association. Assessing the associations among obesity and disease severity, ICU admission, and mechanical ventilation was our secondary endpoint. Results We analyzed data from 317 patients and found no significant difference between obese and non-obese patients regarding frequency of death, invasive mechanical ventilation, ICU admission, CURB-65, or qSOFA scores (P>0.05). After adjusting for confounding factors, obese diabetic COVID-19 patients were 2.72 times more likely to die than non-obese patients. Moreover, ventilator dependence (adjusted odds ratio [aOR], 1.87; 95% confidence interval [CI], 1.03-4.76) and ICU admission (aOR, 2.41; 95% CI, 1.11-5.68) odds were significantly higher for obese patients than non-obese patients. Conclusion The results of the present study indicated that obesity worsens health outcomes for diabetic COVID-19 patients.

Abstract
Die Pneumonie ist eine bei alten Menschen häufige und schwere Erkrankung. Sie steht in dieser Patientengruppe an vierter Stelle der zum Tode führenden Erkrankungen. Die Diagnose kann oft aufgrund einer atypischen klinischen Präsentation schwierig sein. Daher sollte bei jeder Verschlechterung eines alten Menschen ursächlich auch an eine Pneumonie gedacht werden. Geriatrische Probleme wie Gebrechlichkeit und physische und psychische Einschränkungen sollten ebenso erfasst werden wie die soziale Situation, da alle diese Faktoren prognoserelevant sind. Prognostisch ungünstiger verlaufen Pneumonien, die im Pflegeheim oder von Pflegebedürftigen erworben wurden. Sie gelten zwar als ambulant erworben, sollten dennoch besonders beachtet werden. Die Behandlung unterscheidet sich nicht grundsätzlich von der Behandlung jüngerer Patient, sollte aber besondere Situationen wie den in einer Patientenverfügung festgelegten Patientenwunsch bei der Therapieplanung berücksichtigen. Gerade ältere Menschen zeigen unter einer COVID(coronavirus disease)-19-Infektion oft atypische klinische Bilder, sodass bei akuten Veränderungen im Alter auch daran zu denken ist.

Abstract
BACKGROUND The unprecedented COVID-19 pandemic has put a serious burden on the healthcare system worldwide. Due to varied manifestations of SARS-CoV-2 infection, many scoring systems, which were earlier used for community acquired pneumonia (CAP) are in use to determine the disease severity and the need of ICU admissions for proper management. COVID-19 is a relatively new disease and the validity of these scoring systems in SARS-CoV-2 infection is not completely known. This study aimed to validate these scoring systems in cases of COVID-19 pneumonia in an Indian setup. The study has also tried to find the most accurate indicator of disease severity and 14-day mortality among these scoring systems. MATERIALS AND METHODS This study included 122 SARS-CoV-2 infected patients at a tertiary hospital in Ranchi, Jharkhand. The severity of the disease according to ICMR protocol for COVID-19, the PSI/PORT score, the CURB-65 score and the SCAP score were calculated in all the patients and analysed with the disease outcome, that is, 14-day mortality. RESULTS SCAP score, PSI/PORT score and CURB-65 criteria, all were good indicators of disease severity and 14-day mortality. However, when compared to other scoring systems, SCAP score was a more accurate marker of disease severity and 14-day mortality. CONCLUSION The PSI/PORT scoring system, the CURB-65 criteria and the SCAP scoring system can be used to assess the COVID-19 severity and predict the 14-day mortality risk in cases of COVID-19 pneumonia.

Abstract
Novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has rapidly spread throughout the world, resulting in a pandemic with high mortality. There are no effective treatments for the management of severe COVID-19 and current therapeutic trials are focused on antiviral therapy and attenuation of hyper-inflammation with anti-cytokine therapy. Severe COVID-19 pneumonia shares some pathological similarities with severe bacterial pneumonia and sepsis. In particular, it disrupts the haemostatic balance, which results in a procoagulant state locally in the lungs and systemically. This culminates in the formation of microthrombi, disseminated intravascular coagulation and multi-organ failure. The deleterious effects of exaggerated inflammatory responses and activation of coagulation have been investigated in bacterial pneumonia and sepsis and there is recognition that although these pathways are important for the host immune response to pathogens, they can lead to bystander tissue injury and are negatively associated with survival. In the past two decades, evidence from preclinical studies has led to the emergence of potential anticoagulant therapeutic strategies for the treatment of patients with pneumonia, sepsis and acute respiratory distress syndrome, and some of these anticoagulant approaches have been trialled in humans. Here, we review the evidence from preclinical studies and clinical trials of anticoagulant treatment strategies in bacterial pneumonia and sepsis, and discuss the importance of these findings in the context of COVID-19.

Abstract
BACKGROUND While there are ongoing regulatory convergence efforts, differences remain in primary endpoints recommended for community-acquired bacterial pneumonia (CABP) trials. The US Food and Drug Administration recommends assessing CABP symptom resolution at an early time point (3-5 days after randomization). Other regulatory agencies recommend assessing overall clinical response at a later time point (5-10 days after therapy ends). METHODS We analyzed participant-level data from six recent CABP trials submitted to the FDA (n=4,645 participants) to evaluate concordance between early and late endpoint outcomes. We used multivariate logistic regression to identify factors associated with discordance. RESULTS Early and late endpoint outcomes were concordant for 85.6% of participants. The proportions of early endpoint responders that ultimately failed and early endpoint non-responders that ultimately succeeded were similar (6.0% vs 8.4%, respectively). Early endpoint response was highly predictive of late endpoint success (positive predictive value 92.9%). Multivariate logistic regression identified early endpoint responders/late endpoint failures as less likely to be obese and more likely to be infected with Chlamydophila pneumoniae or Staphylococcus aureus, have received antibacterial drug therapy prior to randomization, and have severe chest pain at baseline. The most common investigator-provided reasons for failure among early endpoint responders/late endpoint failures were receipt of non-study antibacterial drug therapy and loss to follow-up. CONCLUSION Early and late endpoint outcomes were highly concordant. These data may be useful in the continuing efforts to reach international regulatory convergence on CABP clinical trial design recommendations.

Abstract
Objectives: To investigate whether confusion, respiratory rate, shock index-age ≥65 years (CRSI-65) score, consisting of basic physiological parameters, can be used for severity prediction in patients with community-acquired pneumonia. Methods: This is a prospective cohort and single-center study conducted in Bolu Abant Izzet Baysal University Hospital, Bolu, Turkey between January 2018 and June 2018. The study investigated CRSI-65 score in predicting 4-week mortality and the need for intensive care for patients with community-acquired pneumonia. Results: A total of 58 patients with community-acquired pneumonia admitted to the emergency department were included in this study. Of the patients, 62.1% were males (n=36), and the mean age of the patients was 72.87 ± 12.30 years. After 4 weeks of follow-up, CURB-65 and CRSI-65 scores showed similar results in predicting mortality with respect to specificity, sensitivity, and positive and negative predictive values. Area under the receiver operating characteristic curve was 0.926 for the CURB-65 (95% confidence interval [CI] 0.853-0.999) and 0.954 for the CRSI-65 (95% CI 0.899-0.999). Conclusion: Similar to the CURB-65 score, the CRSI-65 score appears to be useful in predicting 4-week mortality. The evaluation of CRSI-65 score can be used in emergency department triage, primary care, and non-hospital settings.

Abstract
Background Most international guidelines recommend empirical therapy for community-acquired pneumonia (CAP) to be based on site of care. Some patients with severe CAP are managed in general wards because of limited intensive care unit (ICU) bed or because of unrecognition of the pneumonia severity. Appropriate initial antibiotic treatment for severe CAP outside ICU has not yet been established. This study aimed to determine the prevalence and the impact of initial antibiotic selection on the outcomes of patients with severe CAP who were admitted and managing in general wards. Methods This prospective observational study included consecutive patients hospitalized for presumed CAP in general wards over a 1-year period. Severe CAP was identified using the 2007 Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) criteria. Initial antibiotic treatment in the first 24 h were collected. The primary outcome was the rate of unfavorable outcome (composite outcome of treatment failure and in-hospital death). The secondary outcome was the number of hospital-free days assessed 30 days after enrollment into the study. Results There were 94 patients hospitalized with CAP of which 50 (53.2%) patients were compatible with severe CAP. An etiologic diagnosis was found in 43 (45.8%) patients. The most common pathogens identified in patients with severe CAP were Staphylococcus aureus (28.6%) and Klebsiella pneumoniae (28.6%), followed by Pseudomonas aeruginosa (17.9%). Patients with severe CAP had significantly more positive blood culture than patients with non-severe CAP (24% VS 4.5%; p = .008). Initial antibiotic treatment were discordant with the IDSA/ATS guidelines in 42% of all patients hospitalized with CAP, and 52% of patients with severe CAP. Multivariate analysis revealed that age (OR 1.1, 95% CI 1.01–1.1) and initial antibiotic treatment discordant to guidelines for severe CAP in ICU (OR 4.6, 95% CI 1.3–17.1) were independent risk factors of the unfavorable outcome of patients with severe CAP. Patients with unfavorable outcome had lower number of hospital-free days than patients with favorable outcome (5.2 ± 8 days VS 18 ± 7.1 days; p < .001). Conclusions Patients with severe CAP outside ICU should be recognized for appropriate initial antibiotic selection to improve outcomes.

Abstract
Community-acquired pneumonia (CAP) is one of the most common infectious diseases, as well as a major cause of death both in developed and developing countries, and it remains a challenge for physicians around the world. Several guidelines have been published to guide clinicians in how to diagnose and take care of patients with CAP. However, there are still many areas of debate and uncertainty where research is needed to advance patient care and improve clinical outcomes. In this review we highlight current hot topics in CAP and present updated evidence around these areas of controversy. Community-acquired pneumonia is the most frequent cause of infectious death worldwide; however, there are several areas of controversy that should be addressed to improve patient care. This review presents the available data on these topics.http://bit.ly/2ShnH7A

Abstract
OBJECTIVE Pneumonia is a leading cause of mortality worldwide, especially in the elderly. The use of clinical risk scores to determine prognosis is complex and therefore leads to errors in clinical practice. Pneumonia can cause increases in the levels of cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP). The prognostic role of the NT-proBNP level in community acquired pneumonia (CAP) remains unclear. The aim of this study was to evaluate the prognostic role of the NT-proBNP level in patients with CAP, as well as its correlation with clinical risk scores. METHODS Consecutive inpatients with CAP were enrolled in the study. At hospital admission, venous blood samples were collected for the evaluation of NT-proBNP levels. The Pneumonia Severity Index (PSI) and the Confusion, Urea, Respiratory rate, Blood pressure, and age ≥ 65 years (CURB-65) score were calculated. The primary outcome of interest was all-cause mortality within the first 30 days after hospital admission, and a secondary outcome was ICU admission. RESULTS The NT-proBNP level was one of the best predictors of 30-day mortality, with an area under the curve (AUC) of 0.735 (95% CI: 0.642-0.828; p < 0.001), as was the PSI, which had an AUC of 0.739 (95% CI: 0.634-0.843; p < 0.001), whereas the CURB-65 had an AUC of only 0.659 (95% CI: 0.556-0.763; p = 0.006). The NT-proBNP cut-off level found to be the best predictor of ICU admission and 30-day mortality was 1,434.5 pg/mL. CONCLUSIONS The NT-proBNP level appears to be a good predictor of ICU admission and 30-day mortality among inpatients with CAP, with a predictive value for mortality comparable to that of the PSI and better than that of the CURB-65 score.

Abstract
BACKGROUND Guideline-based empiric antimicrobial therapy is recommended for the treatment of community-acquired pneumonia (CAP). In this study, we evaluate the pattern of empiric antibiotics of CAP patients. MATERIALS AND METHODS Patients with CAP were retrieved from the health information unit using the International Classification of Diseases, Ninth Revision. The electronic pharmacy database was used to retrieve prescribed antibiotics and the duration of therapy for each antibiotic. RESULTS A total of 1672 adult patients were included in the study and 868 (52%) were male. Of all the patients, 47 (2.8%) were admitted to the intensive care unit (ICU). The most frequently used antibiotics were levofloxacin (68.12%), ceftriaxone (37.7%), imipenem-cilastatin (32.5%), and azithromycin (20.6%). The mean days of therapy of each of these antibiotics were 3.2, 2.8, 4.4, and 2.9, respectively. A combination therapy of levofloxacin and imipenem-cilastatin was prescribed for 355 (21.8%) of non-ICU patients versus 20 (60.6%) of ICU patients (P = 0.0007). Imipenem-cilastatin was prescribed for 518 (31.8%) of non-ICU patients versus 25 (56.8%) of ICU patients (P = 0.0009). Levofloxacin was prescribed for 1106 (68%) of non-ICU patients versus 33 (75%) of ICU patients (P = 0.412). Ceftriaxone use decreased significantly from 40.9% in 2013 to 25.9% in 2016 (P = 0.034). In addition, levofloxacin use increased from 63.7% to 75% (P = 0.63). CONCLUSION The most commonly used antibiotics were levofloxacin, ceftriaxone, imipenem-cilastatin, and azithromycin. The data call for further refinement and prospective audit of antibiotic use in CAP, especially in non-ICU settings.

Abstract
Acute systemic inflammatory conditions are accompanied by profound alterations of metabolism. However, the role of fibroblast growth factor 21 (FGF21), a recently identified central regulator of metabolism, is largely unknown in community-acquired pneumonia (CAP). This study aims to characterise the pattern of FGF21 in pneumonia and associations with disease severity and outcome.This is a secondary analysis of two independent multicentre randomised controlled trials in patients presenting to the emergency department with CAP. Primary and secondary efficacy parameters included 30-day mortality, length of hospital stay, time to clinical stability and duration of antibiotic treatment.A total of 509 patients were included in the analysis. FGF21 levels at admission strongly correlated with disease severity, as measured by the Pneumonia Severity Index. Increased levels of FGF21 were associated with prolonged time to clinical stability, antibiotic treatment and hospitalisation. FGF21 levels at admission were significantly higher in nonsurvivors than in survivors, yielding a 1.61-fold increased adjusted odds ratio of 30-day mortality (95% CI 1.21–2.14; p=0.001). Moreover, FGF21 was found to identify patients for 30-day mortality with superior discriminative power compared with routine diagnostic markers.Moderate-to-severe CAP patients with higher levels of FGF21 were at increased risk for clinical instability, prolonged hospitalisation and 30-day all-cause mortality.

Abstract
This article aimed to review the current prognostic and diagnostic tools used for community-acquired pneumonia (CAP) and highlight those potentially applicable in children with CAP. Several scoring systems have been developed to predict CAP mortality risk and serve as guides for admission into the intensive care unit. Over the years, clinicians have adopted these tools for improving site-of-care decisions because of high mortality rates in the extremes of age. The major scoring systems designed for geriatric patients include the Pneumonia Severity Index and the confusion, uremia, respiratory rate, blood pressure, age >65 years (CURB-65) rule, as well as better predictors of intensive care unit admission, such as the systolic blood pressure, multilobar chest radiography involvement, albumin level, respiratory rate, tachycardia, confusion, oxygenation and arterial pH (SMART-COP) score, the Infectious Diseases Society of America/American Thoracic Society guidelines, the criteria developed by España et al as well as the systolic blood pressure, oxygenation, age and respiratory rate (SOAR) criteria. Only the modified predisposition, insult, response and organ dysfunction (PIRO) score has so far been applied to children with CAP. Because none of the tools is without its limitations, there has been a paradigm shift to incorporate biomarkers because they are reliable diagnostic tools and good predictors of disease severity and outcome, irrespective of age group. Despite the initial preponderance of reports on their utility in geriatric CAP, much progress has now been made in demonstrating their usefulness in pediatric CAP.

Abstract
BACKGROUND Early prediction of the clinical outcomes for health care-associated pneumonia (HCAP) patients is challenging. OBJECTIVES This is the first study to evaluate procalcitonin (PCT) as a predictor of outcomes in HCAP patients. METHODS We conducted an observational study based on data for HCAP patients prospectively collected between 2011 and 2014. Outcome variables were intensive care unit (ICU) admission and 30-day mortality. PCT was categorized into three groups: <0.5, 0.5-2.0, and >2.0 ng/ml. We analysed multiple variables including age, sex, comorbidities, clinical findings, and PCT group to assess their association with outcomes. RESULTS Of 245 HCAP patients, 99 (40.4%) were admitted to an ICU and 44 (18.0%) died within 30 days. The median PCT level was significantly higher in the ICU admission (1.19 vs. 0.4 ng/ml; p < 0.001) and 30-day mortality (3.3 vs. 0.4 ng/ml; p < 0.001) groups. In multivariate analysis, high PCT (>2.0 ng/ml) was strongly associated with ICU admission [odds ratio 3.734, 95% confidence interval (CI) 1.753-7.951; p = 0.001] and 30-day mortality (hazard ratio 2.254, 95% CI 1.250-5.340; p = 0.035). In receiver operating characteristic analysis, PCT had a poor discrimination power regarding ICU admission [0.695 of the area under the curve (AUC)] and a fair discrimination power regarding 30-day mortality in HCAP patients (0.768 of the AUC). CONCLUSIONS High PCT on admission was strongly associated with ICU admission and 30-day mortality in HCAP patients. However, application of PCT alone seems to be limited to predicting outcomes.

Abstract
OBJECTIVE Current management of hospitalised patients with community-acquired pneumonia (CAP) in an Australian regional hospital in accordance with the recommended guidelines is unknown. The prescription rate of inappropriate antibiotic therapy was measured and analysed. DESIGN A retrospective audit, December 2012 to November 2013. SETTING Regional Australian hospital in North East Victoria. INTERVENTIONS Interventions were the average of inpatient and intensive care unit length of stay, time to first antibiotic and to first chest X-ray, days of intravenous antibiotics, and extra intravenous therapy; proportion of intensive care unit admissions, average time to first antibiotic administration, patients with failed outpatient management of CAP, initial microbiological investigations, positive investigations, predominant microbiology, antibiotic choice, and concordance with guidelines; proportion of justifiable deviation from guidelines, ratio of patients switched to oral therapy appropriately, complications during therapy, clinical failure, inpatient mortality, mortality at 30 days, mortality at 6 months, and readmission with CAP in 30 days and in 3 months. MAIN OUTCOME MEASURES To improve the rates of concordance with guidelines by following a specified method to rate severity of CAP, to clearly document reasons for non-concordance with guidelines, and to rationalise investigations. RESULTS To improve antibiotic stewardship in the management of CAP. CONCLUSION In an Australian regional hospital, ceftriaxone and azithromycin were the predominant combination used at 56%, demonstrating that mild CAP was frequently overtreated. Mild CAP was eight times more likely to be treated as severe CAP (odds ratio = 8.2 (95% confidence interval, 1.7-40.3) P < 0.009). There is a need for a simple yet effective strategy to be introduced to rationalise treatment and investigation of CAP in this setting.

Abstract
BACKGROUND Although pneumonia severity index (PSI) is widely used to evaluate the severity of community-acquired pneumonia (CAP), the calculation of PSI is very complicated. The present study aimed to evaluate the role of B-type natriuretic peptide (BNP) in predicting the severity of CAP. METHODS For 202 patients with CAP admitted to the emergency department, BNP levels, cardiac load indexes, inflammatory indexes including C-reactive protein (CRP), white blood cell count (WBC), and PSI were detected. The correlation between the indexes and PSI was investigated. BNP levels for survivor and non-survivor groups were compared, and a receiver operating characteristic (ROC) curve analysis was performed on the BNP levels versus PSI. RESULTS The BNP levels increased with CAP severity (r=0.782, P<0.001). The BNP levels of the high-risk group (PSI classes IV and V) were significantly higher than those of the low-risk group (PSI classes I-III) (P<0.001). The BNP levels were significantly higher in the non-survivor group than in the survivor group (P<0.001). In addition, there were positive correlations between BNP levels and PSI scores (r=0.782, P<0.001). The BNP level was highly accurate in predicting the severity of CAP (AUC=0.952). The optimal cut-off point of BNP level for distinguishing high-risk patients from low-risk ones was 125.0 pg/mL, with a sensitivity of 0.891 and a specificity of 0.946. Moreover, BNP level was accurate in predicting mortality (AUC=0.823). Its optimal cut-off point for predicting death was 299.0 pg/mL, with a sensitivity of 0.675 and a specificity of 0.816. Its negative predictive cut-off value was 0.926, and the positive predictive cut-off value was 0.426. CONCLUSION BNP level is positively correlated with the severity of CAP, and may be used as a biomarker for evaluating the severity of CAP.

Abstract
Severe pneumonia is a major cause of mortality in children. The present study evaluated the diagnostic value of serum C-reactive protein (CRP) levels for cases of severe pneumonia. A total of 862 children, hospitalized for acute respiratory tract infections, were evaluated between September 2008 and February 2011; the serum levels of CRP were measured in all the children. Bacterial identification was performed, while polymerase chain reaction was used to detect the 12 respiratory viruses. Multivariate logistic regression analysis was performed with independent [CRP, proportion of neutrophils (NEUT), body temperature, sputum production, age and dyspnea] and dependent (severe and mild pneumonia) variables for clinical diagnosis, which produced three new variables that represented an individual's predictive value: Pre-1, Pre-2 and Pre-3. A receiver operating characteristic (ROC) curve was generated using the new variables to assess their predictive value for severe pneumonia. Of the 862 patients, 108 individuals were diagnosed with severe pneumonia and 754 individuals had mild pneumonia. Increased levels of CRP were associated with severe pneumonia and bacterial infection (P<0.05). Multivariate logistic regression analysis found that severe pneumonia was associated with the levels of CRP, body temperature, expectoration, age, NEUT and dyspnea (P<0.05). The ROC curve of the regression diagnostics model sequentially presented CRP, CRP and the other five correlative variables (NEUT + body temperature + sputum production + age + dyspnea) and the other five correlative variables used to diagnose severe pneumonia. The area under curve values were determined as 0.550 for Pre-1 [95% confidence interval (CI), 0.490-0.609], 0.897 for Pre-2 (95% CI, 0.861-0.932) and 0.893 for Pre-3 (95% CI, 0.855-0.931). The results revealed that the six correlative variables had improved accuracy in the diagnosis of severe pneumonia. The serum levels of CRP were strongly associated with bacterial infection and severe pneumonia. Therefore, the CRP level, along with other parameters, may be used as early indicators of severe pneumonia development. However, the efficiency of the CRP level alone to diagnose severe pneumonia was found to be limited.

Abstract
Background:Mortality of community acquired pneumonia (CAP) remains high despite significant research efforts. Knowledge about comorbidities including chronic obstructive pulmonary disease (COPD) might help to improve management and ultimately, survival. The impact of COPD on CAP severity and mortality remains a point of discussion. Objectives:Assess the prevalence and clinical characteristics of COPD in the observational German Competence Network for CAP, CAPNETZ, and to study the impact of COPD on CAP severity and mortality. Methods:1307 consecutive patients with CAP (57.0% males, age 59.0±18.5), classified as CAP-only (n=1043; 78.0%) and CAP-COPD (n=264; 20.2%) were followed up for 180 days. Associations between CAP, COPD and mortality were evaluated by univariate/multivariate and Kaplan-Meier survival analyses. Results:CAP-COPD patients were older, more often males, current/former smokers, with higher confusion-urea-respiratory rate-blood pressure, (CURB) scores. Length of hospital stay, urea, glucose and leucocytes plasma levels, and arterial carbon dioxide tension (PaCO2) were significantly increased in CAP-COPD. Thirty, 90- and 180-day mortality rates were significantly increased in CAP-COPD (p=0.046, odds ratio [OR]=2.48, 95% confidence interval [CI] 1.015-6.037; p=0.003, OR=2.80, 95%CI 1.430-5.468; p=0.001, OR=2.57, 95%CI 1.462-4.498; respectively). Intensive care unit (ICU)-admission and age, but not COPD, were identified as independent predictors of short- and long-term mortality. Conclusion:Severity as well as mortality was significantly higher in COPD patients with CAP. To improve CAP management with the aim to decrease its still-too-high mortality, underlying comorbidities, particularly COPD, need to be assessed.

Abstract
Objective This study aimed to evaluate Brazilian physicians’ perceptions regarding the
diagnosis, severity assessment, treatment and risk stratification of severe
community-acquired pneumonia patients and to compare those perceptions to current
guidelines. Methods We conducted a cross-sectional international anonymous survey among a convenience
sample of critical care, pulmonary, emergency and internal medicine physicians
from Brazil between October and December 2008. The electronic survey evaluated
physicians’ attitudes towards the diagnosis, risk assessment and therapeutic
interventions for patients with severe community-acquired pneumonia. Results A total of 253 physicians responded to the survey, with 66% from Southeast Brazil.
The majority (60%) of the responding physicians had > 10 years of medical
experience. The risk assessment of severe community-acquired pneumonia was very
heterogeneous, with clinical evaluation as the most frequent approach. Although
blood cultures were recognized as exhibiting a poor diagnostic performance, these
cultures were performed by 75% of respondents. In contrast, the presence of
urinary pneumococcal and Legionella antigens was evaluated by
less than 1/3 of physicians. The vast majority of physicians (95%) prescribe
antibiotics according to a guideline, with the combination of a
3rd/4th generation cephalosporin plus a macrolide as the
most frequent choice. Conclusion This Brazilian survey identified an important gap between guidelines and clinical
practice and recommends the institution of educational programs that implement
evidence-based strategies for the management of severe community-acquired
pneumonia.

Abstract
Background In patients with community-acquired pneumonia (CAP), short-term mortality is largely dependent on pneumonia severity, whereas long-term mortality is considered to depend on comorbidity. However, evidence indicates that severity scores used to assist management decisions at disease onset may also be associated with long-term mortality. Therefore, the objective of the study was to investigate the performance of the pneumonia severity scores CURB-65 and CRB-65 compared to the Charlson Comorbidity Index (CCI) for predicting 1-year mortality in adults discharged from hospital after inpatient treatment for CAP. Methods From a single centre, all cases of patients with CAP treated consecutively as inpatients between 2005 and 2009 and surviving at least 30 days after admission were analysed. The patients’ vital status was obtained from the relevant local register office. CURB-65, CRB-65 and CCI were compared using receiver operating characteristics (ROC) analysis. Results Of 498 cases analysed, 106 (21.3%) patients died within 1 year. In univariate analysis, age ≥65 years, nursing home residency, hemiplegia, dementia and congestive heart failure were significantly associated with mortality. CURB-65, CRB-65 and CCI were also all associated with mortality at 1 year. ROC analysis yielded a weak, yet comparable test performance for CURB-65 (AUC and corresponding 95% confidence interval [CI] for risk categories: 0.652 [0.598-0.706]) and CCI (AUC [CI]: 0.631 [0.575-0.688]; for CRB-65 0.621 [0.565-0.677] and 0.590 [0.533-0.646]). Conclusions Neither CURB-65 or CRB-65 nor CCI allow excellent discrimination in terms of predicting longer term mortality. However, CURB-65 is significantly associated with long-term mortality and performed equally to the CCI in this respect. This fact may help to identify CAP survivors at higher risk after discharge from hospital.

Abstract
Background Community-acquired pneumonia (CAP) is a common cause of patient hospitalization and death, and its burden on the healthcare system is increasing in aging societies. Here, we develop and internally validate risk-adjustment models and scoring systems for predicting mortality in CAP patients to enable more precise measurements of hospital performance. Methods Using a multicenter administrative claims database, we analyzed 35,297 patients hospitalized for CAP who had been discharged between April 1, 2012 and September 30, 2013 from 303 acute care hospitals in Japan. We developed hierarchical logistic regression models to analyze predictors of in-hospital mortality, and validated the models using the bootstrap method. Discrimination of the models was assessed using c-statistics. Additionally, we developed scoring systems based on predictors identified in the regression models. Results The 30-day in-hospital mortality rate was 5.8%. Predictors of in-hospital mortality included advanced age, high blood urea nitrogen level or dehydration, orientation disturbance, respiratory failure, low blood pressure, high C-reactive protein levels or high degree of pneumonic infiltration, cancer, and use of mechanical ventilation or vasopressors. Our models showed high levels of discrimination for mortality prediction, with a c-statistic of 0.89 (95% confidence interval: 0.89-0.90) in the bootstrap-corrected model. The scoring system based on 8 selected variables also showed good discrimination, with a c-statistic of 0.87 (95% confidence interval: 0.86-0.88). Conclusions Our mortality prediction models using administrative data showed good discriminatory power in CAP patients. These risk-adjustment models may support improvements in quality of care through accurate hospital evaluations and inter-hospital comparisons.

Abstract
BACKGROUND Patients with community-acquired pneumonia (CAP) often require hospitalisation. CRB-65 is a simple and useful scoring system to predict mortality. However, prognostic factors such as underlying disease and blood oxygenation are not included despite their potential to increase the performance of CRB-65. METHODS The study included 1172 consecutive patients (830 inpatients, 342 outpatients) with CAP. Mortality, sensitivity, specificity, positive predictive value and negative predictive value, and the area under the receiver operating characteristic (ROC) curve with 95% CI were calculated. Prognostic accuracy was evaluated after adding coexisting illnesses according to the Pneumonia Severity Index (malignancy, heart failure, hepatic, renal and cerebrovascular disease) and pulse oximetry (SpO2). RESULTS Mean age was 65 years, 30-day mortality 7% (inpatients 9%, outpatients 1%). Addition of one point for the presence of ≥1 coexisting condition and one point for SpO2 <90% increased the area under the ROC curve of CRB-65 from 0.82 (95% CI 0.77 to 0.85) to 0.87 (95% CI 0.84 to 0.90; p<0.0001). CONCLUSIONS Modification of CRB-65 by including hypoxaemia and presence of specified underlying diseases increased the scoring system's prognostic accuracy while retaining its independence of laboratory tests. DS CRB-65 may have the potential to further facilitate site of care decision for patients with CAP.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a prevalent and potentially life-threatening infection, and has poor prognosis in aged patients. The objective of this study was to compare the potential of admission N-terminal pro B-type natriuretic peptide (proBNP) levels and scoring models [CURB-65, Pneumonia Severity Index (PSI), and Acute Physiology and Chronic Health Evaluation (APACHE) II scores] to predict outcomes for aged patients with CAP admitted to Intensive Care Unit (ICU), and to explore the prognostic factors. METHODS Clinical data of the patients were collected retrospectively, whose CURB-65, PSI, APACHE II scores were calculated and in whom measurements of proBNP was performed. The outcomes of interest were severity evaluation, prediction of need for mechanical ventilation and 28-day mortality. Receiver operating characteristic (ROC) curve was conducted to predict the assessment ability of proBNP and scoring models on different outcomes, and the logistic regression analysis was performed to screen factors affecting prognosis. RESULTS 240 patients were enrolled, with the mean age of 75±8 years old. Admission levels of NT-proBNP, scoring models were significantly higher in SCAP patients, MV group, and non-survivors compared to non-SCAP patients, no-MV group, and 28-day survivors, respectively (P<0.001). PSI had the highest area under the curve (AUC) and specificity for the three outcomes considered (AUC: 0.868 and specificity: 0.906 for 28-day mortality, AUC: 0.864 and specificity: 0.831 for requirement of MV, and AUC: 0.888 and specificity: 0.894 for severity evaluation). NT-proBNP had the highest sensitivity of 0.987 and 0.903 on prediction of mortality and need for MV. And APACHE II scoring model with the highest sensitivity of 0.890 was used to evaluate severity. Logistic regression analysis showed that the odd ratio (OR) of systolic blood pressure, PSI, and APACHE II scores were 0.886, 1.019, and 1.249. CONCLUSIONS PSI scores was the best indicator in predicting different clinical outcomes of aged patients with CAP among the proBNP and three scoring systems. Systolic blood pressure might be as a protective factor for prognosis while PSI and APACHE II scores as risk factors for prognosis of aged patients with CAP.

Abstract
BACKGROUND Several models have been developed to predict the risk of mortality in community-acquired pneumonia (CAP). This study aims to systematically identify and evaluate the performance of published risk prediction models for CAP. METHODS We searched MEDLINE, EMBASE, and Cochrane library in November 2011 for initial derivation and validation studies for models which predict pneumonia mortality. We aimed to present the comparative usefulness of their mortality prediction. RESULTS We identified 20 different published risk prediction models for mortality in CAP. Four models relied on clinical variables that could be assessed in community settings, with the two validated models BTS1 and CRB-65 showing fairly similar balanced accuracy levels (0.77 and 0.72, resp.), while CRB-65 had AUROC of 0.78. Nine models required laboratory tests in addition to clinical variables, and the best performance levels amongst the validated models were those of CURB and CURB-65 (balanced accuracy 0.73 and 0.71, resp.), with CURB-65 having an AUROC of 0.79. The PSI (AUROC 0.82) was the only validated model with good discriminative ability among the four that relied on clinical, laboratorial, and radiological variables. CONCLUSIONS There is no convincing evidence that other risk prediction models improve upon the well-established CURB-65 and PSI models.

Abstract
Introduction It has been suggested that delayed intensive care unit (ICU) transfer is associated with increased mortality for patients with community-acquired pneumonia (CAP). However, ICU admission policies and patient epidemiology vary widely across the world depending on local hospital practices and organizational constraints. We hypothesized that the time from the onset of CAP symptoms to invasive mechanical ventilation could be a relevant prognostic factor. Methods One hundred patients with a CAP and necessitating invasive mechanical ventilation were included. Prospectively collected data were retrospectively analysed. Two study groups were identified based on the time of the initiation of invasive mechanical ventilation (rapid respiratory failure requiring mechanical ventilation within 72 h of the onset of CAP and progressive respiratory failure requiring invasive mechanical ventilation 4 or more days after the onset of CAP). Results Excepting more COPD patients in the rapid respiratory failure group and more patients with diabetes in the progressive respiratory failure group, these patients had similar characteristics. The overall in-hospital mortality rate was 28% in the rapid respiratory failure group and 51% in the progressive respiratory failure group (P = 0.03). The ICU and the day 30 mortality rates were higher in the progressive respiratory failure group (47% vs. 23%, P = 0.02; and 37.7% vs. 21.3%, P = 0.03; respectively). After adjusting for the propensity score and other potential confounding factors, progressive respiratory failure remained associated with hospital mortality only after 12 days of invasive mechanical ventilation. Conclusions This study suggested that the duration or delay in the time to intubation from the onset of CAP symptoms was associated with the outcomes in those patients who ultimately required invasive mechanical ventilation.

Abstract
INTRODUCTION The site-of-care decision is one of the most important factors in the management of patients with community-acquired pneumonia. The severity scores are validated prognostic tools for community-acquired pneumonia mortality and treatment site decision. The aim of this paper was to compare the discriminatory power of four scores - the classic PSI and CURB65 ant the most recent SCAP and SMART-COP - in predicting major adverse events: death, ICU admission, need for invasive mechanical ventilation or vasopressor support in patients admitted with pneumococcal pneumonia. METHODS A five year retrospective study of patients admitted for pneumococcal pneumonia. Patients were stratified based on admission data and assigned to low-, intermediate-, and high-risk classes for each score. Results were obtained comparing low versus non-low risk classes. RESULTS We studied 142 episodes of hospitalization with 2 deaths and 10 patients needing mechanical ventilation and vasopressor support. The majority of patients were classified as low risk by all scores - we found high negative predictive values for all adverse events studied, the most negative value corresponding to the SCAP score. The more recent scores showed better accuracy for predicting ICU admission and need for ventilation or vasopressor support (mostly for the SCAP score with higher AUC values for all adverse events). CONCLUSIONS The rate of all adverse outcomes increased directly with increasing risk class in all scores. The new gravity scores appear to have a higher discriminatory power in all adverse events in our study, particularly, the SCAP score.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality in Nigeria. Severity assessment is a major starting point in the proper management of CAP. The BTS guideline for managing this condition is simple and does not require sophisticated equipment. Adherence to this guideline will improve CAP management in Nigeria. AIMS To assess the usefulness of the CURB-65 score in the management of CAP patients in Nigeria and to determine the outcome in relation to the degree of severity using CURB-65. METHODS A prospective observational study of 80 patients with CAP was carried out in the University of Nigeria Teaching Hospital Enugu, Nigeria from December 2008 to June 2009. The patients were classified into three risk groups and the ability of the CURB-65 score to predict the 30-day mortality rate and the need for ICU admission was determined. RESULTS Eighty patients were recruited, 39 of whom were men, giving a male to female ratio of 1:1.05. The mean age was 56 ± 18 years. Thirty-seven patients (46.3%) were outpatients, 13 with CURB score 0, 21 with CURB score 1, two with CURB score 2, and one with CURB score 3. Of the 43 patients (53.7%) admitted to hospital, six, 13, 14, and 10 had scores of 4, 3, 2, and 1, respectively. The ICU admission rate was 10%. Twelve patients died, 2.2% in the low-risk group, 12.5% in the intermediate-risk group, and 45% in the high-risk group. CONCLUSIONS The CURB-65 score is a simple method of assessing and risk stratifying CAP patients. It is particularly useful in a busy emergency department because of its ability to identify a reasonable proportion of low-risk patients for potential outpatient care.

Abstract
Where to treat patients is probably the single most important decision in the management of community-acquired pneumonia (CAP), with a substantial impact on both patients' outcomes and health-care costs. Several factors can contribute to the decision of the site of care for CAP patients, including physicians' experience and clinical judgment and severity scores developed to predict mortality, as well as social and health-care-related issues. The recognition, both in the community and in the emergency department, of the presence of severe sepsis and acute respiratory failure and the coexistence with unstable comorbidities other than CAP are indications for hospital admission. In all the other cases, physician's choice to admit CAP patients should be validated against at least one objective tool of risk assessment, with a clear understanding of each score's limitations.

Abstract
Community-acquired pneumonia (CAP) is an infectious respiratory disease with an incidence that ranges from 3 to 8 cases per 1,000 inhabitants per year. This incidence increases with age and comorbidities. Forty per cent of CAP patients require hospitalization and around 10% of these patients are admitted in an Intensive Care Unit (ICU). Several studies have suggested that the implementation of clinical guidelines has a positive impact in the outcome of patients including mortality and length of stay. The more recent and used guidelines are those from Infectious Diseases Society of America/American Thoracic Society, published in 2007, the 2009 from the British Thoracic Society, and that from the European Respiratory Society/European Society of Clinical Microbiology and Infectious Diseases, published in 2010. In Spain, the most recently released guideline is the Sociedad Española de Neumología y Cirugía Torácica-2011 guideline. The present guidelines GNAC are designed to be used by the majority of health-care professionals that can participate in the care of CAP patients including diagnosis, decision of hospital and ICU admission, treatment and prevention. The Centro Cochrane Iberoamericano (CCIB) has participated in summarizing the previous guidelines and in the bibliography search. For each one of the following sections the panel of experts has developed a table with recommendations classified according to its evidence, strength and practical applicability using the Grading of Recommendations of Assessment Development and Evaluations (GRADE) system: 1. Epidemiology, microbiological etiology and antibiotic resistances.2. Clinical and microbiological diagnosis.3. Prognostic scales and decision of hospital admission.4. ICU admission criteria. 5. Empirical and definitive antibiotic treatment.6. Treatment failure. 7. Prevention.

Abstract
OBJECTIVES The Risk of Early Admission to the Intensive Care Unit (REA-ICU) index is a clinical prediction model that was derived based on 4,593 patients with community-acquired pneumonia (CAP) for predicting early admission to the intensive care unit (ICU; i.e., within 3 days following emergency department [ED] presentation). This study aimed to validate the REA-ICU index in an independent sample. METHODS The authors retrospectively stratified 850 CAP patients enrolled in a multicenter prospective randomized trial conducted in Switzerland, using the REA-ICU index, alternate clinical prediction models of severe pneumonia (SMART-COP, CURXO-80, and the 2007 IDSA/ATS minor severity criteria), and pneumonia severity assessment tools (the Pneumonia Severity Index [PSI] and CURB-65). RESULTS The rate of early ICU admission did not differ between the validation and derivation samples within each risk class of the REA-ICU index, ranging from 1.1% to 1.8% in risk class I to 27.1% to 27.6% in risk class IV. The areas under the receiver operating characteristic (ROC) curve were 0.76 (95% confidence interval [CI] = 0.70 to 0.83) and 0.80 (95% CI = 0.77 to 0.83) in the validation and derivation samples, respectively. In the validation sample, the REA-ICU index performed better than the pneumonia severity assessment tools, but failed to demonstrate an accuracy advantage over alternate prediction models in predicting ICU admission. CONCLUSIONS The REA-ICU index reliably stratifies CAP patients into four categories of increased risk for early ICU admission within 3 days following ED presentation. Further research is warranted to determine whether inflammatory biomarkers may improve the performance of this clinical prediction model.

Abstract
Introduction Severity assessment and site-of-care decisions for patients with community-acquired pneumonia (CAP) are pivotal for patients' safety and adequate allocation of resources. Late admission to the intensive care unit (ICU) has been associated with increased mortality in CAP. We aimed to review and meta-analyze systematically the performance of clinical prediction rules to identify CAP patients requiring ICU admission or intensive treatment. Methods We systematically searched Medline, Embase, and the Cochrane Controlled Trials registry for clinical trials evaluating the performance of prognostic rules to predict the need for ICU admission, intensive treatment, or the occurrence of early mortality in patients with CAP. Results Sufficient data were available to perform a meta-analysis on eight scores: PSI, CURB-65, CRB-65, CURB, ATS 2001, ATS/IDSA 2007, SCAP score, and SMART-COP. The estimated AUC of PSI and CURB-65 scores to predict ICU admission was 0.69. Among scores proposed for prediction of ICU admission, ATS-2001 and ATS/IDSA 2007 scores had better operative characteristics, with a sensitivity of 70% (CI, 61 to 77) and 84% (48 to 97) and a specificity of 90% (CI, 82 to 95) and 78% (46 to 93), but their clinical utility is limited by the use of major criteria. ATS/IDSA 2007 minor criteria have good specificity (91% CI, 84 to 95) and moderate sensitivity (57% CI, 46 to 68). SMART-COP and SCAP score have good sensitivity (79% CI, 69 to 97, and 94% CI, 88 to 97) and moderate specificity (64% CI, 30 to 66, and 46% CI, 27 to 66). Major differences in populations, prognostic factor measurement, and outcome definition limit comparison. Our analysis also highlights a high degree of heterogeneity among the studies. Conclusions New severity scores for predicting the need for ICU or intensive treatment in patients with CAP, such as ATS/IDSA 2007 minor criteria, SCAP score, and SMART-COP, have better discriminative performances compared with PSI and CURB-65. High negative predictive value is the most consistent finding among the different prediction rules. These rules should be considered an aid to clinical judgment to guide ICU admission in CAP patients.

Abstract
OBJETIVO: Avaliar a concordância entre os critérios de hospitalização utilizados para a admissão de pacientes com pneumonia adquirida na comunidade (PAC) e aqueles da Sociedade Brasileira de Pneumologia e Tisiologia e avaliar a associação dessa concordância com a taxa de mortalidade em 30 dias. Secundariamente, avaliar a associação da concordância entre o tratamento instituído e as recomendações dessas diretrizes com duração da internação hospitalar, investigação microbiológica, mortalidade em 12 meses, complicações, internação em UTI, ventilação mecânica e mortalidade em 30 dias. MÉTODOS: Estudo retrospectivo que incluiu pacientes adultos internados entre 2005 e 2007 no Hospital das Clínicas da Universidade Federal de Minas Gerais, na cidade de Belo Horizonte (MG). Foram revisados prontuários e radiografias de tórax. RESULTADOS: Dentre os 112 pacientes incluídos, os critérios de internação e de tratamento foram concordantes com as diretrizes em 82 (73,2%) e 66 (58,9%), respectivamente. A taxa de mortalidade em 30 dias e em 12 meses foi de 12,3% e 19,4%, respectivamente. Pacientes com escore de CRP-65 (Confusão mental, frequência Respiratória, Pressão arterial e idade > 65 anos) de 1-2 e com antibioticoterapia concordante com as diretrizes foram associados a menor mortalidade em 30 dias (p = 0,01). Doença cerebrovascular e tratamento antibiótico adequado apresentaram associações independentes com mortalidade em 30 dias. Houve uma tendência de associação entre antibioticoterapia concordante e menor duração da internação hospitalar. CONCLUSÕES: Na população estudada, os critérios de hospitalização e de antibioticoterapia concordantes com as diretrizes associaram-se a desfechos favoráveis do tratamento de pacientes hospitalizados com PAC. Doença cerebrovascular, como fator de risco, e antibioticoterapia concordante, como fator protetor, associaram-se à mortalidade em 30 dias.

Abstract
BACKGROUND Aspiration pneumonia is associated with a high morbidity and mortality in elderly patients. In order to provide risk-adapted medical care, it is necessary to establish valid prognostic tools for these patients. OBJECTIVE The value of two well-established scores to assess prognosis in community-acquired pneumonia (CAP), i.e., CURB-65 and the Pneumonia Severity Index (PSI), was evaluated in elderly patients hospitalized for aspiration pneumonia. MATERIAL AND METHODS A total of 209 patients hospitalized with aspiration pneumonia between 2001 and 2005 in a single center were evaluated using PSI and CURB-65. For comparison of morbidity and mortality, an equally large group of inpatients with CAP was analyzed. RESULTS The mean age of patients with aspiration pneumonia was 76.7 ± 13.4 years, and 104 (49.8 %) were female. Patients with aspiration pneumonia more frequently showed a history of cancer, hypotension, and hyponatriemia on admission. Mortality was clearly higher in comparison to patients with CAP (39.2% vs. 16.3%). The Odds Ratio (OR) for mortality was 1.03 (95% CI 0.59; 1.79) for a CURB-65 score of 3-5 points compared to 0-2 points. In cases of CAP, OR showed a statistically significant increase of risk (OR 2.50; 95% CI 1.04; 6.06), for CURB-65 scores of 3-5 points vs. 0-2 points). In aspiration pneumonia, the PSI showed a trend towards increasing mortality within higher risk class. CONCLUSIONS In geriatric patients hospitalized with aspiration pneumonia, CURB-65 and PSI have no prognostic value.

Abstract
OBJECTIVES The objective was to compare outcomes associated with early, late, and no admission to the intensive care unit (ICU) for patients hospitalized with community-acquired pneumonia (CAP). METHODS This was a post hoc analysis of the original data from the Emergency Department Community-Acquired Pneumonia (EDCAP) and Pneumocom-1 prospective multicenter cohort studies of adult patients hospitalized with CAP. Propensity score-adjusted analysis was used to compare 28-day mortality and hospital length of stay (LOS) for 199, 144, and 2,215 patients with early (i.e., ICU admission on the day of emergency department [ED] presentation), late, and no ICU admission. RESULTS Unadjusted 28-day mortality rates were 13.1, 19.4, and 5.7% for early, late, and no ICU admissions, respectively (p < 0.001). After adjusting for quintile of propensity score, the odds of 28-day mortality were higher for late ICU admissions relative to early ICU admissions (odds ratio [OR] = 2.63; 95% confidence interval [CI] = 1.42 to 4.90), and no ICU admissions (OR = 3.40; 95% CI = 2.11 to 5.48), but did not differ between early and no ICU admissions (OR = 1.29; 95% CI = 0.79 to 2.09). The median hospital LOS was 10 days for early (interquartile range [IQR] = 7 to 18), 15 days for late (IQR 9 to 23), and 6 days (IQR 4 to 9) for no ICU admissions (p < 0.001). CONCLUSIONS This study suggests that late but not early admission to the ICU is associated with higher 28-day mortality for patients hospitalized with CAP. Patients admitted to the ICU have longer hospital LOS in comparison to those managed on the wards, particularly if they are admitted late to the ICU.

Abstract
Community-acquired pneumonia (CAP) is a common infectious disease that still causes substantial morbidity and mortality. Elderly people are frequently affected, and several issues related to care of this condition in the elderly have to be considered. This article reviews current recommendations of guidelines with a special focus on aspects of the care of elderly patients with CAP. The most common pathogen in CAP is still Streptococcus pneumoniae, followed by other pathogens such as Haemophilus influenzae, Mycoplasma pneumoniae, Chlamydophila pneumoniae and Legionella species. Antimicrobial resistance is an increasing problem, especially with regard to macrolide-resistant S. pneumoniae and fluoroquinolone-resistant strains. With regard to β-lactam antibacterials, resistance by H. influenzae and Moraxella catarrhalis is important, as is the emergence of multidrug-resistant Staphylococcus aureus. The main management decisions should be guided by the severity of disease, which can be assessed by validated clinical risk scores such as CURB-65, a tool for measuring the severity of pneumonia based on assessment of confusion, serum urea, respiratory rate and blood pressure in patients aged ≥65 years. For the treatment of low-risk pneumonia, an aminopenicillin such as amoxicillin with or without a β-lactamase inhibitor is frequently recommended. Monotherapy with macrolides is also possible, although macrolide resistance is of concern. When predisposing factors for special pathogens are present, a β-lactam antibacterial combined with a β-lactamase inhibitor, or the combination of a β-lactam antibacterial, a β-lactamase inhibitor and a macrolide, may be warranted. If possible, patients who have undergone previous antibacterial therapy should receive drug classes not previously used. For hospitalized patients with non-severe pneumonia, a common recommendation is empirical antibacterial therapy with an aminopenicillin in combination with a β-lactamase inhibitor, or with fluoroquinolone monotherapy. With proven Legionella pneumonia, a combination of β-lactams with a fluoroquinolone or a macrolide is beneficial. In severe pneumonia, ureidopenicillins with β-lactamase inhibitors, broad-spectrum cephalosporins, macrolides and fluoroquinolones are used. A combination of a broad-spectrum β-lactam antibacterial (e.g. cefotaxime or ceftriaxone), piperacillin/tazobactam and a macrolide is mostly recommended. In patients with a predisposition for Pseudomonas aeruginosa, a combination of piperacillin/tazobactam, cefepime, imipenem or meropenem and levofloxacin or ciprofloxacin is frequently used. Treatment duration of more than 7 days is not generally recommended, except for proven infections with P. aeruginosa, for which 15 days of treatment appears to be appropriate. Further care issues in all hospitalized patients are timely administration of antibacterials, oxygen supply in case of hypoxaemia, and fluid management and dose adjustments according to kidney function. The management of elderly patients with CAP is a challenge. Shifts in antimicrobial resistance and the availability of new antibacterials will change future clinical practice. Studies investigating new methods to detect pathogens, determine the optimal antimicrobial regimen and clarify the duration of treatment may assist in further optimizing the management of elderly patients with CAP.
