Abstract
BACKGROUND Hospitalization rates for childhood pneumonia vary widely. Risk-based clinical decision support (CDS) interventions may reduce unwarranted variation. METHODS We conducted a pragmatic randomized trial in two US pediatric emergency departments (EDs) comparing electronic health record (EHR)-integrated prognostic CDS versus usual care for promoting appropriate ED disposition in children (<18 years) with pneumonia. Encounters were randomized 1:1 to usual care versus custom CDS featuring a validated pneumonia severity score predicting risk for severe in-hospital outcomes. Clinicians retained full decision-making authority. The primary outcome was inappropriate ED disposition, defined as early transition to lower- or higher-level care. Safety and implementation outcomes were also evaluated. RESULTS The study enrolled 536 encounters (269 usual care and 267 CDS). Baseline characteristics were similar across arms. Inappropriate disposition occurred in 3% of usual care encounters and 2% of CDS encounters (adjusted odds ratio: 0.99, 95% confidence interval: [0.32, 2.95]) Length of stay was also similar and adverse safety outcomes were uncommon in both arms. The tool's custom user interface and content were viewed as strengths by surveyed clinicians (>70% satisfied). Implementation barriers include intrinsic (e.g., reaching the right person at the right time) and extrinsic factors (i.e., global pandemic). CONCLUSIONS EHR-based prognostic CDS did not improve ED disposition decisions for children with pneumonia. Although the intervention's content was favorably received, low subject accrual and workflow integration problems likely limited effectiveness. Clinical Trials Registration: NCT06033079.

Abstract
Pneumonia, classified as a lower respiratory tract illness, affects different parts of the bronchial system as well as alveoli and can present with varying severities depending on co-morbidities and causative pathogens. It can be broadly classified using the setting in which it was acquired, namely the community or hospital setting, the former being more common and spreading through person-to-person droplet transmission. Community-acquired pneumonia (CAP) is currently the fourth leading cause of death worldwide, and its high mortality makes continual insight into the management of the condition worthwhile. This review explores the literature specifically for severe CAP (sCAP) and delves into the diagnosis, various modalities of treatment, and management of the condition. This condition can be defined as pneumonia requiring mechanical ventilation in the ICU and/or presenting with sepsis and organ failure due to pneumonia. The disease process is characterized by inflammation of the lung parenchyma, initiated by a combination of pathogens and lowered local defenses. Acute diagnosis of the condition is vital in reducing negative patient outcomes, namely through clinical presentation, blood/sputum cultures, imaging modalities such as computed tomography scan, and inflammatory markers, identifying common causative pathogens such as Streptococcus pneumoniae, rhinovirus, Legionella, and viral influenza. Pathogens such as Escherichia coli should also be investigated in patients with chronic obstructive pulmonary disease. The mainstay of treating sCAP includes rapid ICU admission once a diagnosis has been confirmed, initiating sepsis protocol, and treatment with combined empiric antibiotic regimens consisting of beta-lactams and macrolides. Corticosteroid use alongside antibiotics shows promise in reducing inflammation, but its use has to be judged on a case-by-case basis. New drugs such as omadacycline, delafloxacin, and zabofloxacin have shown valid evidence for the treatment of resistant causative organisms. The main guidelines for preventing sCAP include maintaining a healthy lifestyle, and annual pneumococcal and influenza vaccines are recommended for the most vulnerable patient groups, such as those with COPD and immunosuppression.

Abstract
Lower respiratory infections include acute bronchitis, influenza, community-acquired pneumonia, acute exacerbation of COPD and acute exacerbation of bronchiectasis. They are a major cause of death worldwide and often affect the most vulnerable: children, elderly and the impoverished. In this paper, we review the clinical presentation, diagnosis, severity assessment and treatment of adult outpatients with lower respiratory infections. The paper is divided into sections on specific lower respiratory infections, but we also dedicate a section to COVID-19 given the importance of the ongoing pandemic. Lower respiratory infections are heterogeneous entities, carry different risks for adverse events, and require different management strategies. For instance, while patients with acute bronchitis are rarely admitted to hospital and generally do not require antimicrobials, approximately 40% of patients seen for community-acquired pneumonia require admission. Clinicians caring for patients with lower respiratory infections face several challenges, including an increasing population of patients with immunosuppression, potential need for diagnostic tests that may not be readily available, antibiotic resistance and social aspects that place these patients at higher risk. Management principles for patients with lower respiratory infections include knowledge of local surveillance data, strategic use of diagnostic tests according to surveillance data, and judicious use of antimicrobials.

Abstract
INTRODUCTION Pneumonia is the top communicable cause of death worldwide. Accurate prognostication of patient severity with Community Acquired Pneumonia (CAP) allows better patient care and hospital management. The Pneumonia Severity Index (PSI) was developed in 1997 as a tool to guide clinical practice by stratifying the severity of patients with CAP. While the PSI has been evaluated against other clinical stratification tools, it has not been evaluated against multiple classic machine learning classifiers in various metrics over large sample size. METHODS In this paper, we evaluated and compared the prediction performance of nine classic machine learning classifiers with PSI over 34,720 adult (age 18+) patient records collected from 749 hospitals from 2009 to 2018 in the United States on Receiver Operating Characteristic (ROC) Area Under the Curve (AUC) and Average Precision (Precision-Recall AUC). RESULTS Machine learning classifiers, such as Random Forest, provided a statistically highly(p < 0.001) significant improvement (∼33% in PR AUC and ∼6% in ROC AUC) compared to PSI and required only 7 input values (compared to 20 parameters used in PSI). DISCUSSION Because of its ease of use, PSI remains a very strong clinical decision tool, but machine learning classifiers can provide better prediction accuracy performance. Comparing prediction performance across multiple metrics such as PR AUC, instead of ROC AUC alone can provide additional insight.

Abstract
Rationale: Computerized severity assessment for community-acquired pneumonia could improve consistency and reduce clinician burden. Objectives: To develop and compare 30-day mortality-prediction models using electronic health record data, including a computerized score with all variables from the original Pneumonia Severity Index (PSI) except confusion and pleural effusion ("ePSI score") versus models with additional variables. Methods: Among adults with community-acquired pneumonia presenting to emergency departments at 117 Veterans Affairs Medical Centers between January 1, 2006, and December 31, 2016, we compared an ePSI score with 10 novel models employing logistic regression, spline, and machine learning methods using PSI variables, age, sex and 26 physiologic variables as well as all 69 PSI variables. Models were trained using encounters before January 1, 2015; tested on encounters during and after January 1, 2015; and compared using the areas under the receiver operating characteristic curve, confidence intervals, and patient event rates at a threshold PSI score of 970. Results: Among 297,498 encounters, 7% resulted in death within 30 days. When compared using the ePSI score (confidence interval [CI] for the area under the receiver operating characteristic curve, 0.77-0.78), performance increased with model complexity (CI for the logistic regression PSI model, 0.79-0.80; CI for the boosted decision-tree algorithm machine learning PSI model using the Extreme Gradient Boosting algorithm [mlPSI] with the 19 original PSI factors, 0.83-0.85) and the number of variables (CI for the logistic regression PSI model using all 69 variables, 0.84-085; CI for the mlPSI with all 69 variables, 0.86-0.87). Models limited to age, sex, and physiologic variables also demonstrated high performance (CI for the mlPSI with age, sex, and 26 physiologic factors, 0.84-0.85). At an ePSI score of 970 and a mortality-risk cutoff of <2.7%, the ePSI score identified 31% of all patients as being at "low risk"; the mlPSI with age, sex, and 26 physiologic factors identified 53% of all patients as being at low risk; and the mlPSI with all 69 variables identified 56% of all patients as being at low risk, with similar rates of mortality, hospitalization, and 7-day secondary hospitalization being determined. Conclusions: Computerized versions of the PSI accurately identified patients with pneumonia who were at low risk of death. More complex models classified more patients as being at low risk of death and as having similar adverse outcomes.

Abstract
This clinical policy from the American College of Emergency Physicians is a revision of the 2009 "Clinical Policy: Critical Issues in the Management of Adult Patients Presenting to the Emergency Department With Community-Acquired Pneumonia." A writing subcommittee conducted a systematic review of the literature to derive evidence-based recommendations to answer the following clinical questions: (1) In the adult emergency department patient diagnosed with community-acquired pneumonia, what clinical decision aids can inform the determination of patient disposition? (2) In the adult emergency department patient with community-acquired pneumonia, what biomarkers can be used to direct initial antimicrobial therapy? (3) In the adult emergency department patient diagnosed with community-acquired pneumonia, does a single dose of parenteral antibiotics in the emergency department followed by oral treatment versus oral treatment alone improve outcomes? Evidence was graded and recommendations were made based on the strength of the available data.

Abstract
Background: This document provides evidence-based clinical practice guidelines on the management of adult patients with community-acquired pneumonia. Methods: A multidisciplinary panel conducted pragmatic systematic reviews of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations. Results: The panel addressed 16 specific areas for recommendations spanning questions of diagnostic testing, determination of site of care, selection of initial empiric antibiotic therapy, and subsequent management decisions. Although some recommendations remain unchanged from the 2007 guideline, the availability of results from new therapeutic trials and epidemiological investigations led to revised recommendations for empiric treatment strategies and additional management decisions. Conclusions: The panel formulated and provided the rationale for recommendations on selected diagnostic and treatment strategies for adult patients with community-acquired pneumonia.

Abstract
Reduction of the inappropriate use of antibiotics in clinical practice is one of the main goals of the Società Italiana di Medicina Interna (SIMI) choosing wisely campaign. We conducted a systematic review of secondary studies (systematic reviews and guidelines) to verify what evidence is available on the duration of antibiotic treatment in Pneumonia. A literature systematic search was performed to identify all systematic reviews and the three most cited and recent guidelines that address the duration of antibiotic therapy in pneumonia. Moreover, a meta-analysis of non-duplicate data from randomized controlled trials (RCTs) considered in the enrolled systematic reviews was performed together with a trial sequential analysis to identify the need for further studies. Two systematic reviews on antibiotic duration in community-acquired pneumonia (CAP) for a total of 17 RCTs (2764 patients) were enrolled in our study. Meta-analysis of non-duplicate RCTs show a non-significant difference in rate of treatment failure between short (≤ 7 days) and long (> 7 days) antibiotic treatment course: RR 1.05 (95% CI, 0.82-1.36). The trial sequential analysis suggests that further data would not affect current evidence or become clinically relevant. Selected guidelines suggest consideration of a short course, with a low grade of evidence and without citing the already published systematic reviews. Antibiotic treatment of CAP for ≤ 7 days is not associated with a higher rate of treatment failure than longer courses and should thus be taken in consideration. Guidelines should upgrade the evidence on this topic.

Abstract
PURPOSE OF REVIEW To describe the current understanding and clinical applicability of severity scoring systems in pneumonia management. RECENT FINDINGS Severity scores in community-acquired pneumonia are strong markers of mortality, but are not necessarily clinical decision-aid tools. The use of severity scores to support outpatient care in low-risk patients has moderate-to-strong evidence available in the literature, mainly for the pneumonia severity index, and must be applied together with clinical judgment. It is not clear that severity scores are helpful to guide empiric antibiotic treatment. The inclusion of biomarkers and performance status might improve the predictive performance of the well known severity scores in community-acquired pneumonia. We should improve our methods for score evaluation and move toward the development of decision-aid tools. SUMMARY The application of the available evidence favors the use of severity scoring systems to improve the delivery of care for pneumonia patients. The incorporation of new methodologies and the formulation of different questions other than mortality prediction might help the further development of severity scoring systems, and enhance their support to the clinical decision-making process for the pneumonia-management cascade.

Abstract
This study of ventilated patients investigated pneumonia risk factors and outcome predictors in 476 episodes of pneumonia (48% community-acquired pneumonia, 24% hospital-acquired pneumonia, 28% ventilator-associated pneumonia) using a prospective survey in 14 intensive care units within Australia and New Zealand. For community acquired pneumonia, mortality increased with immunosuppression (OR 5.32, CI 95% 1.58–17.99, P<0.01), clinical signs of consolidation (OR 2.43, CI 95% 1.09–5.44, P=0.03) and Sepsis-Related Organ Failure Assessment (SOFA) scores (OR 1.19, CI 95% 1.08–1.30, P<0.001) but improved if appropriate antibiotic changes were made within three days of intensive care unit admission (OR 0.42, CI 95% 0.20–0.86, P=0.02). For hospital-acquired pneumonia, immunosuppression (OR 6.98, CI 95% 1.16–42.2, P=0.03) and non-metastatic cancer (OR 3.78, CI 95% 1.20–11.93, P=0.02) were the principal mortality predictors. Alcoholism (OR 7.80, CI 95% 1.20–17.50, P<0.001), high SOFA scores (OR 1.44, CI 95% 1.20–1.75, P=0.001) and the isolation of “high risk” organisms including Pseudomonas aeruginosa, Acinetobacter spp, Stenotrophomonas spp and methicillin resistant Staphylococcus aureus (OR 4.79, CI 95% 1.43–16.03, P=0.01), were associated with increased mortality in ventilator-associated pneumonia. The use of non-invasive ventilation was independently protective against mortality for patients with community-acquired and hospital-acquired pneumonia (OR 0.35, CI 95% 0.18–0.68, P=0.002). Mortality was similar for patients requiring both invasive and non-invasive ventilation and non-invasive ventilation alone (21% compared with 20% respectively, P=0.56). Pneumonia risks and mortality predictors in Australian and New Zealand ICUs vary with pneumonia type. A history of alcoholism is a major risk factor for mortality in ventilator-associated pneumonia, greater in magnitude than the mortality effect of immunosuppression in hospital-acquired pneumonia or community-acquired pneumonia. Non-invasive ventilation is associated with reduced ICU mortality. Clinical signs of consolidation worsen, while rationalising antibiotic therapy within three days of ICU admission improves mortality for community-acquired pneumonia patients.

Abstract
Community-acquired pneumonia is common and important infectious disease in adults. This work represents an update to 2009 treatment guideline for community-acquired pneumonia in Korea. The present clinical practice guideline provides revised recommendations on the appropriate diagnosis, treatment, and prevention of community-acquired pneumonia in adults aged 19 years or older, taking into account the current situation regarding community-acquired pneumonia in Korea. This guideline may help reduce the difference in the level of treatment between medical institutions and medical staff, and enable efficient treatment. It may also reduce antibiotic resistance by preventing antibiotic misuse against acute lower respiratory tract infection in Korea.

Ferrari R, Viale P, Muratori P, Giostra F, Agostinelli D, Lazzari R, Voza R, Cavazza M. Rebounds after discharge from the emergency department for community-acquired pneumonia: focus on the usefulness of severity scoring systems. ACTA BIO-MEDICA : ATENEI PARMENSIS 2018; 88:519-528. [PMID: 29350672 PMCID: PMC6166183 DOI: 10.23750/abm.v88i4.6685] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Revised: 09/26/2017] [Accepted: 09/26/2017] [Indexed: 11/23/2022]
Abstract
Background: Community-acquired pneumonia (CAP) is common cause of hospital admission and leading cause of morbidity and mortality. Severity scoring systems are used to predict risk profile, outcome and mortality, and to help decisions about management strategies. Aim of the work and Methods: To critically analyze pneumonia “rebound” cases, once discharged from the emergency department (ED) and afterwards admitted. We conducted an observational clinical study in the acute setting of a university teaching hospital, prospectively analyzing, in a 1 year period, demographic, medical, clinical and laboratory data, and the outcome. Results: 249 patients were discharged home with diagnosis of CAP; 80 cases (32.1%) resulted in the high-intermediate risk class according to CURB-65 or CRB-65. Twelve patients (4.8%) presented to the ED twice and were then admitted. At their first visit 5 were in the high-intermediate risk group; just 4 of them were in the non-low risk group at the time of their admission. The rebound cohort showed some peculiar abnormalities in laboratory parameters (coagulation and renal function) and severe chest X-rays characteristics. None died in 30 days. Conclusions: The power of CURB-65 to correctly predict mortality for CAP patients discharged home from the ED is not confirmed by our results; careful clinical judgement seems to be irreplaceable in the management process. Many patients with a high-intermediate risk according to CURB-65 can be safely treated as outpatients, according to adequate welfare conditions; we identified a subgroup of cases that should worth a special attention and, therefore, a brief observation period in the ED before the final decision to safely discharge or admit.

Abstract
Introduction The Pneumonia Patient Outcomes Research Team (PORT) derived and validated a Prediction Rule to identify low-risk patients with community-acquired pneumonia (CAP).1 This prediction rule was implemented in the Accident & Emergency (A&E) Department of Prince of Wales Hospital to help select patients suitable for outpatient treatment. Materials & Methods A retrospective study of all cases of CAP admitted from A&E, age above 14, over a six-month period (the period of implementation of the Prediction Rule) was performed. Patients belonging to the low-risk categories were identified after review of the records. Factors likely to influence the admission decision were noted. Descriptive statistics was generated. Results Eighty-five patients were identified, 61 (71.8%) females and 24 (28.2%) males. The mean age was 59.1 years (±17.3 years, SD). Fifty-three (62.3%) patients had at least one significant comordid condition (e.g. chronic lung disease, diabetes). Of the remaining patients, 20 (23.5%) had at least one identifiable factor (e.g. haemoptysis, multilobar infiltrates in chest radiograph) influencing the hospitalisation decision; and only 12 (14.1%) had no reason, identifiable retrospectively, to justify hospitalised care. Conclusions A substantial number of low-risk patients with CAP (classified according to the Prediction Rule) were admitted. Most of these patients had identifiable comorbid conditions and prognostic factors that had not been accounted for by the Prediction Rule guidelines. Further evaluation of the significance of these additional variables is required in order to give the guidelines a better predictive value.

Emergency Medicine Evaluation of Community-Acquired Pneumonia: History, Examination, Imaging and Laboratory Assessment, and Risk Scores. J Emerg Med 2017; 53:642-652.

Abstract
BACKGROUND Pneumonia is a common infection, accounting for approximately one million hospitalizations in the United States annually. This potentially life-threatening disease is commonly diagnosed based on history, physical examination, and chest radiograph. OBJECTIVE To investigate emergency medicine evaluation of community-acquired pneumonia including history, physical examination, imaging, and the use of risk scores in patient assessment. DISCUSSION Pneumonia is the number one cause of death from infectious disease. The condition is broken into several categories, the most common being community-acquired pneumonia. Diagnosis centers on history, physical examination, and chest radiograph. However, all are unreliable when used alone, and misdiagnosis occurs in up to one-third of patients. Chest radiograph has a sensitivity of 46-77%, and biomarkers including white blood cell count, procalcitonin, and C-reactive protein provide little benefit in diagnosis. Biomarkers may assist admitting teams, but require further study for use in the emergency department. Ultrasound has shown utility in correctly identifying pneumonia. Clinical gestalt demonstrates greater ability to diagnose pneumonia. Clinical scores including Pneumonia Severity Index (PSI); Confusion, blood Urea nitrogen, Respiratory rate, Blood pressure, age 65 score (CURB-65); and several others may be helpful for disposition, but should supplement, not replace, clinical judgment. Patient socioeconomic status must be considered in disposition decisions. CONCLUSION The diagnosis of pneumonia requires clinical gestalt using a combination of history and physical examination. Chest radiograph may be negative, particularly in patients presenting early in disease course and elderly patients. Clinical scores can supplement clinical gestalt and assist in disposition when used appropriately.

Abstract
Background There is a lack of severity assessment tools to identify adults presenting with febrile urinary tract infection (FUTI) at risk for complicated outcome and guide admission policy. We aimed to validate the Prediction Rule for Admission policy in Complicated urinary Tract InfeCtion LEiden (PRACTICE), a modified form of the pneumonia severity index, and to subsequentially assess its use in clinical practice. Methods A prospective observational multicenter study for model validation (2004–2009), followed by a multicenter controlled clinical trial with stepped wedge cluster-randomization for impact assessment (2010–2014), with a follow up of 3 months. Paricipants were 1157 consecutive patients with a presumptive diagnosis of acute febrile UTI (787 in validation cohort and 370 in the randomized trial), enrolled at emergency departments of 7 hospitals and 35 primary care centers in the Netherlands. The clinical prediction rule contained 12 predictors of complicated course. In the randomized trial the PRACTICE included guidance on hospitalization for high risk (>100 points) and home discharge for low risk patients (<75 points), in the control period the standard policy regarding hospital admission was applied. Main outcomes were effectiveness of the clinical prediction rule, as measured by primary hospital admission rate, and its safety, as measured by the rate of low-risk patients who needed to be hospitalized for FUTI after initial home-based treatment, and 30-day mortality. Results A total of 370 patients were included in the randomized trial, 237 in the control period and 133 in the intervention period. Use of PRACTICE significantly reduced the primary hospitalization rate (from 219/237, 92%, in the control group to 96/133, 72%, in the intervention group, p < 0.01). The secondary hospital admission rate after initial outpatient treatment was 6% in control patients and 27% in intervention patients (1/17 and 10/37; p < 0.001). Conclusions Although the proposed PRACTICE prediction rule is associated with a lower number of hospital admissions of patients presenting to the ED with presumptive febrile urinary tract infection, futher improvement is necessary to reduce the occurrence of secondary hospital admissions.

Abstract
BACKGROUND Clinicians have limited ability to classify risk of prolonged hospitalization among patients with lower limb cellulitis. OBJECTIVE We sought to identify characteristics associated with days to discharge and prolonged stay. METHODS We conducted retrospective cohort analysis including patients admitted with a primary diagnosis of lower limb cellulitis at community and tertiary hospitals. RESULTS There were 4224 admissions for lower limb cellulitis among 3692 patients. Mean age of the cohort was 64.4 years. Frequencies of tobacco smoking, obesity, and diabetes mellitus were 25.1%, 44.9%, and 19.3%, respectively. Patients having decreased likelihood of discharge included those with the following: 10-year age increments 0.90 (95% confidence interval [CI] 0.88-0.92), obesity 0.90 (95% CI 0.83-0.97), diabetes mellitus 0.90 (95% CI 0.82-0.98), tachycardia 0.76 (95% CI 0.67-0.85), hypotension 0.77 (95% CI 0.65-0.90), leukocytosis 0.86 (95% CI 0.79-0.93), neutrophilia 0.80 (95% CI 0.73-0.87), elevated serum creatinine 0.74 (95% CI 0.68-0.81), and low serum bicarbonate 0.84 (95% CI 0.75-0.95). LIMITATIONS This analysis is retrospective and based on coded data. Unknown confounding variables may also influence prolonged stay. CONCLUSIONS Patients with lower limb cellulitis and prolonged stay have a number of clinical characteristics which may be used to classify risk for prolonged stay.

Abstract
INTRODUCTION Community-acquired pneumonia (CAP) is one of the most common causes of mortality world-wide. The mortality rate of patients with CAP is influenced by the severity of the disease, treatment failure and the requirement for hospitalization and/or intensive care unit (ICU) management, all of which may be predicted by biomarkers and clinical scoring systems. Areas covered: We review the recent literature examining the efficacy of established and newly-developed clinical scores, biological and inflammatory markers such as C-Reactive protein (CRP), procalcitonin (PCT) and Interleukin-6 (IL-6), whether used alone or in conjunction with clinical severity scores to assess the severity of CAP, predict treatment failure, guide acute in-hospital or ICU admission and predict mortality. Expert commentary: The early prediction of treatment failure using clinical scores and biomarkers plays a developing role in improving survival of patients with CAP by identifying high-risk patients requiring hospitalization or ICU admission; and may enable more efficient allocation of resources. However, it is likely that combinations of scoring systems and biomarkers will be of greater use than individual markers. Further larger studies are needed to corroborate the additive value of these markers to clinical prediction scores to provide a safer and more effective assessment tool for clinicians.

Abstract
BACKGROUND Substantial morbidity and excessive care variation are seen with pediatric pneumonia. Accurate risk-stratification tools to guide clinical decision-making are needed. METHODS We developed risk models to predict severe pneumonia outcomes in children (<18 years) by using data from the Etiology of Pneumonia in the Community Study, a prospective study of community-acquired pneumonia hospitalizations conducted in 3 US cities from January 2010 to June 2012. In-hospital outcomes were organized into an ordinal severity scale encompassing severe (mechanical ventilation, shock, or death), moderate (intensive care admission only), and mild (non-intensive care hospitalization) outcomes. Twenty predictors, including patient, laboratory, and radiographic characteristics at presentation, were evaluated in 3 models: a full model included all 20 predictors, a reduced model included 10 predictors based on expert consensus, and an electronic health record (EHR) model included 9 predictors typically available as structured data within comprehensive EHRs. Ordinal regression was used for model development. Predictive accuracy was estimated by using discrimination (concordance index). RESULTS Among the 2319 included children, 21% had a moderate or severe outcome (14% moderate, 7% severe). Each of the models accurately identified risk for moderate or severe pneumonia (concordance index across models 0.78-0.81). Age, vital signs, chest indrawing, and radiologic infiltrate pattern were the strongest predictors of severity. The reduced and EHR models retained most of the strongest predictors and performed as well as the full model. CONCLUSIONS We created 3 risk models that accurately estimate risk for severe pneumonia in children. Their use holds the potential to improve care and outcomes.

Abstract
OBJECTIVE To investigate the accuracy of the National Early Warning Score (NEWS) to predict mortality and adverse clinical outcomes for patients with community-acquired pneumonia (CAP) compared to standard risk scores such as the pneumonia severity index (PSI) and CURB-65. DESIGN Secondary analysis of patients included in a previous randomised-controlled trial with a median follow-up of 6.1 years. SETTINGS Patients with CAP included on admission to the emergency departments (ED) of 6 tertiary care hospitals in Switzerland. PARTICIPANTS A total of 925 patients with confirmed CAP were included. NEWS, PSI and CURB-65 scores were calculated on admission to the ED based on admission data. MAIN OUTCOME MEASURE Our primary outcome was all-cause mortality within 6 years of follow-up. Secondary outcomes were adverse clinical outcome defined as intensive care unit (ICU) admission, empyema and unplanned hospital readmission all occurring within 30 days after admission. We used regression models to study associations of baseline risk scores and outcomes with the area under the receiver operating curve (AUC) as a measure of discrimination. RESULTS 6-year overall mortality was 45.1% (n=417) with a stepwise increase with higher NEWS categories. For 30 day and 6-year mortality prediction, NEWS showed only low discrimination (AUC 0.65 and 0.60) inferior compared to PSI and CURB-65. For prediction of ICU admission, NEWS showed moderate discrimination (AUC 0.73) and improved the prognostic accuracy of a regression model, including PSI (AUC from 0.66 to 0.74, p=0.001) and CURB-65 (AUC from 0.64 to 0.73, p=0.015). NEWS was also superior to PSI and CURB-65 for prediction of empyema, but did not well predict rehospitalisation. CONCLUSIONS NEWS provides additional prognostic information with regard to risk of ICU admission and complications and thereby improves traditional clinical-risk scores in the management of patients with CAP in the ED setting.

Abstract
The authors sought to assess physician awareness and usage of American Thoracic Society guidelines for early conversion from intravenous to oral antibiotics ("switch therapy") in those with community-acquired pneumonia (CAP). We then determined if adoption of a CAP guideline would improve either. Patients (N = 510) hospitalized with CAP from June 2002 to May 2003 were identified retrospectively, and chart reviews were done on a random sample (130 [25%]) of these. Physicians were surveyed before and after guideline adoption. Community-acquired pneumonia guideline implementation increased physician awareness of American Thoracic Society recommendations (5% to 40%) and use of switch therapy (60% to 86%). Such use resulted in decreased overall length of stay from 3.6 to 2.4 days (P < .05) and from 2.91 to 2.41 days (P < .05) among early-switch candidates. Early-switch therapy was not optimally used prior to implementation of this CAP guideline. Adoption of the guideline increased awareness and reduced length of stay among inpatients with CAP.

Abstract
Community acquired pneumonia (CAP) represents the sixth cause of death and the first cause of death for an infectious disease in the USA. The aim of the present study is to evaluate how CAP is managed in a hospital setting, with particular attention to the wards of internal medicine, compared to the recommendations based and validated PSI (Pneumonia Severity Index). 42 subjects were included in the study, 25 males and 17 females. According to the PSI, nine (21%) patients were classified in class I, two (5%) in class II, ten (24%) in class III, fifteen (36%) in class IV and six (14%) in class V. Three patients died during the stay in the hospital (2 males and 1 female), all in the highest PSI class (V). According to the criteria used to evaluate the adequacy of the admission to the hospital, twentyeight patients were classified in the HRG, with an appropriate admission, whilst fourteen (33%) were in the LRG, with an inappropriate admission to the hospital. The data of the study confirm the validity of a PSI based strategy for the management of CAP since admittance to the hospital. This approach is not yet widely implemented in Italy, and a better dialogue between hospital and health system representatives would be convenient, to reduce costs and ensure the safety of patients affected by CAP.

Therefore, we tried to create a mortality prediction rule that is simple and suitable for non-elderly patients with community-acquired pneumonia. METHODS Because of low mortality at young age, we used information from an administrative database that included A-DROP data. We analysed the rate and risk factors for in-hospital community-acquired pneumonia-associated death among non-elderly patients and created a mortality prediction rule based on those risk factors. RESULTS We examined 49,370 hospitalisations for patients aged 18-64 years with community-acquired pneumonia. The 30-day fatality rate was 1.5%. Using regression analysis, five risk factors were selected: patient requires help for feeding, the existence of malignancy, confusion, low blood pressure, and age 40-64 years. Each risk factor of our proposed mortality risk scoring system received one point. A total point score for each patient was obtained by summing the points. The negative likelihood ratio for the score 0 group was 0.01, and the positive likelihood ratio for the score ≥4 group was 19.9. The area under the curve of the risk score for non-elderly (0.86, 95% confidence interval: 0.84-0.87) was higher than that of the A-DROP score (0.72, 95% confidence interval: 0.70-0.74) (P < 0.0001). CONCLUSIONS Our newly proposed mortality risk scoring system may be appropriate for predicting mortality in non-elderly patients with community-acquired pneumonia. It showed a possibility of a better prediction value than the A-DROP and is easy to use in various clinical settings.

Abstract
STUDY OBJECTIVE The aim of this study was to investigate the prognostic prediction power of a newly introduced early warning score modified by serum lactate level, the National Early Warning Score-Lactate (NEWS-L) score, among community-acquired pneumonia (CAP) patients. We also compared the NEWS-L score with the pneumonia severity index (PSI) and CURB-65. METHODS We designed a retrospective observational study and collected data on confirmed adult CAP patients who visited the study hospital between October 2013 and September 2014. Variables relevant to, the NEWS-L score, PSI, and CURB-65 were extracted from electronic medical records. Survival status at hospital discharge was determined in the same manner. The NEWS-L score was calculated as NEWS-L=NEWS+serum lactate level (mmol/L). The NEWS-L was divided into quartiles. The ability to predict mortality was assessed through area under the receiver operating characteristic curve analysis and calibration analysis. RESULTS A total of 553 patients were enrolled, and the inpatient mortality rate was 10.8% (n=60). Mortality rates increased incrementally in conjunction with the NEWS-L quartiles: first quartile, 2.2%; second quartile, 7.9%; third quartile, 9.6%; and fourth quartile, 23.9%. The area under the receiver operating characteristic curve of the NEWS-L score was 0.73 (95% confidence interval [CI], 0.66-0.80), which showed no significant difference from that of the PSI (0.68; 95% CI, 0.61-0.76; P=.28) and CURB-65 (0.66; 95% CI, 0.59-0.73; P=.06). CONCLUSIONS The newly introduced early warning score modified by serum lactate level, NEWS-L score, was comparable to PSI and CURB-65, for predicting inpatient mortality among adult CAP patients.

Abstract
Introduction Emergency department (ED) hospitalizations for skin and soft tissue infection (SSTI) have increased, while concern for costs has grown and outpatient parenteral antibiotic options have expanded. To identify opportunities to reduce admissions, we explored factors that influence the decision to hospitalize an ED patient with a SSTI. Methods We conducted a prospective study of adults presenting to 12 U.S. EDs with a SSTI in which physicians were surveyed as to reason(s) for admission, and clinical characteristics were correlated with disposition. We employed chi-square binary recursive partitioning to assess independent predictors of admission. Serious adverse events were recorded. Results Among 619 patients, median age was 38.7 years. The median duration of symptoms was 4.0 days, 96 (15.5%) had a history of fever, and 46 (7.5%) had failed treatment. Median maximal length of erythema was 4.0cm (IQR, 2.0–7.0). Upon presentation, 39 (6.3%) had temperature >38°C, 81 (13.1%) tachycardia, 35 (5.7%), tachypnea, and 5 (0.8%) hypotension; at the time of the ED disposition decision, these findings were present in 9 (1.5%), 11 (1.8%), 7 (1.1%), and 3 (0.5%) patients, respectively. Ninety-four patients (15.2%) were admitted, 3 (0.5%) to the intensive care unit (ICU). Common reasons for admission were need for intravenous antibiotics in 80 (85.1%; the only reason in 41.5%), surgery in 23 (24.5%), and underlying disease in 11 (11.7%). Hospitalization was significantly associated with the following factors in decreasing order of importance: history of fever (present in 43.6% of those admitted, and 10.5% discharged; maximal length of erythema >10cm (43.6%, 11.3%); history of failed treatment (16.1%, 6.0%); any co-morbidity (61.7%, 27.2%); and age >65 years (5.4%, 1.3%). Two patients required amputation and none had ICU transfer or died. Conclusion ED SSTI patients with fever, larger lesions, and co-morbidities tend to be hospitalized, almost all to non-critical areas and rarely do they suffer serious complications. The most common reason for admission is administration of intravenous antibiotics, which is frequently the only reason for hospitalization. With the increasing outpatient intravenous antibiotic therapy options, these results suggest that many hospitalized patients with SSTI could be managed safely and effectively as outpatients.

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
Severe community-acquired pneumonia (CAP) is a life-threatening condition that requires intensive care unit (ICU) admission. Clinical presentation is characterized by the presence of respiratory failure, severe sepsis, or septic shock. Severe CAP accounts for approximately 5-35% of hospital-treated cases of pneumonia with the majority of patients having underlying comorbidities. The most common pathogens associated with this disease are Streptococcus pneumoniae, Legionella spp., Haemophilus influenzae, and Gram-negative enteric rods. Microbial investigation is probably helpful in the individual case but is likely to be more useful for defining local antimicrobial policies. The early and rapid initiation of empiric antimicrobial treatment is critical for a favorable outcome. It should include intravenous beta-lactam along with either a macrolide or a fluoroquinolone. Modifications of this basic regimen should be considered in the presence of distinct comorbid conditions and risk factors for specific pathogens. Other promising nonantimicrobial new therapies are currently being investigated. The assessment of severity of CAP helps physicians to identify patients who could be managed safely in an ambulatory setting. It may also play a crucial role in decisions about length of hospital stay and time of switching to oral antimicrobial therapy in different groups at risk. The most important adverse prognostic factors include advancing age, male sex, poor health of patient, acute respiratory failure, severe sepsis, septic shock, progressive radiographic course, bacteremia, signs of disease progression within the first 48-72 hours, and the presence of several different pathogens such as S. pneumoniae, Staphylococcus aureus, Gram-negative enteric bacilli, or Pseudomonas aeruginosa. However, some important topics of severity assessment remain controversial, including the definition of severe CAP. Prediction rules for complications or death from CAP, although far from perfect, should identify the majority of patients with severe CAP and be used to support decision-making by the physician. They may also contribute to the evaluation of processes and outcomes of care for patients with CAP.

Abstract
Outpatient management of community-acquired pneumonia (CAP) has several potential advantages, including significant cost-savings, a reduction in hospital-acquired infections and increased patient satisfaction. Despite the benefits, it is often difficult to identify which patients may be managed in the community without compromising patient safety. CAP severity scores, such as the pneumonia severity index (PSI) and the British Thoracic Society CURB65/CRB65 scores are designed to identify groups of patients at low risk of mortality who may be suitable for outpatient care. This review discusses the strengths and weaknesses of severity scores for use in determining site of care for patients with pneumonia. Use of the PSI in emergency departments has been shown to increase the proportion of patients treated in the community without increasing patient mortality or hospital readmissions. The CURB65 and CRB65 scores are less complex alternatives to the PSI that have been shown to perform similarly for prediction of 30-day mortality. All 3 scores identify populations at low risk of mortality who may be eligible for outpatient care. Nevertheless, a number of factors not included in severity scores may prevent discharge of these patients, including social factors, co-morbidities and severity markers not captured by severity scores. The limitations of severity scores are discussed along with recent attempts to improve predictive tools, with the development of new biomarkers and alternative scoring systems.

Abstract
Background The vast majority of research in the area of community-acquired pneumonia (CAP) has been based on patients admitted to hospital. And yet, the majority of patients with CAP are treated on an ambulatory basis as outpatients, either by primary care physicians or in Emergency Departments. Few studies have been conducted in outpatients with pneumonia, and there is a paucity of data on short and long term morbidity or mortality and associated clinical correlates in this group of patients. Methods From 2000–2002, all CAP patients presenting to 7 Emergency Departments in Edmonton, Alberta, Canada were prospectively enrolled in a population-based registry. Clinical data, including pneumonia severity index (PSI) were collected at time of presentation. Patients discharged to the community were then followed for up to 5 years through linkage to the provincial administrative databases. The current report provides the rationale and design for the cohort, as well as describes baseline characteristics and 30-day morbidity and mortality. Results The total sample included 3874 patients. After excluding patients who were hospitalized, died or returned to the Emergency Department the same day they were initially discharged (n = 451; 12 %), and patients who could not be linked to provincial administrative databases (n = 237; 6 %), the final cohort included 3186 patients treated according to a validated clinical management pathway and discharged back to the community. Mean age was 51 (SD = 20) years, 53 % male; 4 % resided in a nursing home, 95 % were independently mobile, and 88 % had mild (PSI class I-III) pneumonia. Within 30-days, return to Emergency Department was common (25 %) as was hospitalization (8 %) and 1 % of patients had died. Conclusions To our knowledge, this represents the largest clinically-detailed outpatient CAP cohort assembled to date and will add to our understanding of the determinants and outcomes in this under-researched patient population. The rich clinical data along with the long term health care utilization and mortality will allow for the identification of novel prognostic indicators. Given how under studied this population is, the findings should aid clinicians in the routine care of their outpatients with pneumonia and help define the next generation of research questions.

Abstract
INTRODUCTION In community-acquired pneumonia, severity assessment tools, such as CRB65, CURB65 and Pneumonia Severity Index (PSI), have been promoted to increase the proportion of patients treated in the community. The prognostic accuracy of these scores is established in hospitalized patients, but less is known about their use in out-patients. We aimed to study the accuracy of these severity tools to predict mortality in patients managed as out-patients. METHODS We performed a systematic review and meta-analysis according to MOOSE guidelines. From 1980 to 2010, we identified 13 studies reporting prognostic information for the CRB65, CURB65 and PSI severity scores in out-patients (either exclusively managed in the community or discharged from an emergency department <24 h after admission). Two reviewers independently collected data and assessed study quality. Performance characteristics across the studies were pooled using a random-effects model. Relationships between sensitivity and specificity were plotted using summary receiver operator characteristic curves (sROC). RESULTS Out-patient mortality ranged from 0% to 3.5%. Four studies were identified for CRB65, 2 for CURB65 and 10 for PSI. Mortality was low for out-patients in the low-risk CRB65 classes [CRB65 0 or 1: mortality occurred in 3 of 1494 patients (0.2%)] but higher in CRB65 Groups 2-4 [mortality 13 of 154 patients (8.4%)]. Similarly, mortality was low in PSI Classes I-III [mortality 8 of 3655 patients (0.2%)] managed as out-patients but higher in Classes IV and V [mortality 32 of 317 patients (10.1%)]. CRB65 showed pooled sensitivity of 81% (54-96%), pooled specificity of 91% (90-93%) and the area under the sROC was 0.91 [standard error (SE) 0.05]. For PSI, pooled sensitivity was 92% (64-100%), pooled specificity was 90% (89-91%) and area under the sROC was 0.92 (SE 0.03). There were insufficient studies to analyse CURB65. CONCLUSION The limited data available suggest that CRB65 and PSI can identify groups of patients at low risk of mortality that can be safely managed in the community.

Hospital admission decision for patients with community-acquired pneumonia: variability among physicians in an emergency department. Ann Emerg Med 2011; 59:35-41.

Abstract
STUDY OBJECTIVE We examine variability among emergency physicians in rate of hospitalization for patients with pneumonia and the effect of variability on clinical outcomes. METHODS We studied 2,069 LDS Hospital emergency department (ED) patients with community-acquired pneumonia who were aged 18 years or older during 1996 to 2006, identified by International Classification of Diseases, Ninth Revision coding and compatible chest radiographs. We extracted vital signs, laboratory and radiographic results, hospitalization, and outcomes from the electronic medical record. We defined "low severity" as PaO(2)/FiO(2) ratio greater than or equal to 280 mm Hg, predicted mortality less than 5% by an electronic version of CURB-65 that uses continuous and weighted elements (eCURB), and less than 3 Infectious Disease Society of America-American Thoracic Society 2007 severe pneumonia minor criteria. We adjusted hospitalization decisions and outcomes for illness severity and patient demographics. RESULTS Initial hospitalization rate was 58%; 10.7% of patients initially treated as outpatients were secondarily hospitalized within 7 days. Median age of admitted patients was 63 years; median eCURB predicted mortality was 2.65% (mean 6.8%) versus 46 years and 0.93% for outpatients. The 18 emergency physicians (average age 44.9 [standard deviation 7.6] years; years in practice 8.4 [standard deviation 6.9]) objectively calculated and documented illness severity in 2.7% of patients. Observed 30-day mortality for inpatients was 6.8% (outpatient mortality 0.34%) and decreased over time. Individual physician admission rates ranged from 38% to 79%, with variability not explained by illness severity, time of day, day of week, resident care in conjunction with an attending physician, or patient or physician demographics. Higher hospitalization rates were not associated with reduced mortality or fewer secondary hospital admissions. CONCLUSION We observed a 2-fold difference in pneumonia hospitalization rates among emergency physicians, unexplained by objective data.

Abstract
To enhance the quality of patient care, Hamad Medical Corporation (HMC) has previously adopted guidelines for the management of community-acquired pneumonia (CAP) based upon the PSI model. We audited retrospectively the management of CAP inpatients admitted to Hamad General Hospital from 1 January until 31 June, 2008 with the objective of establishing whether these HMC guidelines were being implemented appropriately. Sixty-nine patients with CAP were admitted during the study period. Guidelines for the assessment of disease severity at presentation were not followed in all patients. Appropriate antibiotic therapy was instituted in 52 (75.4%) cases. Ten patients died (14.5%). The rate of use of a severity assessment score to stratify patients with CAP based on recognized guidelines was zero and the death rate of 14.5% might reflect that noncompliance.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is a common reason for admissions in the emergency department (ED). However, patient disposition is not always standardized. OBJECTIVE To evaluate the effect of incorporating a pneumonia severity index (PSI) on admission rates and medical costs in CAP patients presenting to the ED. METHODS From April 2008 to March 2009, CAP patients presenting to the ED were prospectively screened and low-risk CAP patients (PSI I, II, or III) were enrolled (after group). Discharge and outpatient care were recommended for this group in the absence of other medical conditions requiring hospitalization. Data from low-risk CAP patients from May 2003 to October 2006 were also collected for comparative analysis (before group). RESULTS There were 365 and 174 patients in the before and after groups, respectively. The admission rate of the after group was significantly lower than that of the before group (30.4% vs. 68.2%, p < 0.01). The subsequent admission rates after ED discharge due to CAP were similar (3.2% vs. 7.7%, p = 0.10). The ultimate admission rate in the after group was significantly lower than that in the before group (32.5% vs. 70.7%, p < 0.01). Direct medical costs per patient for the before and after groups were $US 1532 and $US 1186, respectively (p = 0.03). CONCLUSIONS Incorporation of the PSI into the admission protocol for ED patients with CAP significantly reduced the admission rates and medical costs.

Abstract
One of the most important decisions in the management of community-acquired pneumonia is deciding the care site, which affects morbidity, mortality, and costs. Clinical judgment alone is difficult and imprecise. The Pneumonia Severity Index score and the CURB-65 (confusion, urea nitrogen, respiratory rate, blood pressure, 65 years of age and older) score are validated prognostic indices to predict mortality, and they can identify low-risk patients who may be eligible for outpatient management. However, limitations of the scoring systems preclude their isolated use, and they can only be recommended as an aid to guide hospital admission decisions. The Pneumonia Severity Index score is slightly better at identifying the lowest risk patients, whereas CURB-65 is much simpler to use. As an adjunct to clinical judgment, we consider CURB-65 to be the most useful prognostic index for identifying low-risk patients.

Abstract
Community-acquired pneumonia continues to be the acute infectious disease that has the greatest medical and social impact regarding morbidity and treatment costs. Children and the elderly are more susceptible to severe complications, thereby justifying the fact that the prevention measures adopted have focused on these age brackets. Despite the advances in the knowledge of etiology and physiopathology, as well as the improvement in preliminary clinical and therapeutic methods, various questions merit further investigation. This is due to the clinical, social, demographical and structural diversity, which cannot be fully predicted. Consequently, guidelines are published in order to compile the most recent knowledge in a systematic way and to promote the rational use of that knowledge in medical practice. Therefore, guidelines are not a rigid set of rules that must be followed, but first and foremost a tool to be used in a critical way, bearing in mind the variability of biological and human responses within their individual and social contexts. This document represents the conclusion of a detailed discussion among the members of the Scientific Board and Respiratory Infection Committee of the Brazilian Thoracic Association. The objective of the work group was to present relevant topics in order to update the previous guidelines. We attempted to avoid the repetition of consensual concepts. The principal objective of creating this document was to present a compilation of the recent advances published in the literature and, consequently, to contribute to improving the quality of the medical care provided to immunocompetent adult patients with community-acquired pneumonia.

Abstract
The objective was to evaluate the utility of the Pneumonia Severity Index (PSI) developed by Fine et al. as a tool to streamline diagnostic and therapeutic effort. Site of care of patients was recommended in accordance with the PSI class: classes I and II underwent treatment at home and classes III, IV, and V were hospitalized. Class I comprised 37 patients; class II had 30, class III had 20, class IV had 31, and class V had 10 patients. 80 patients were admitted into the hospital, 3 of whom required admittance to the intensive care unit, and 48 were managed as outpatients from the emergency room. Overall mortality was 4 patients (3.1%). Of these, 3 belonged to class IV and 1 to class V. The aetiological diagnosis was obtained in 53.9% of the cases (69/128). If classes I to III are analysed together, the percentage of aetiological diagnoses was 47% (41/87), increasing to 68% (28/41) for patients in classes IV and V. In our experience Fine's PSI classification, with rationalization and adaptation to the particularities of each centre, is an effective tool for deciding on hospitalization for selecting the most suitable battery of diagnostic tests based on cost-benefit criteria. However, it is inadequate for young patients with hypoxia or pleural effusion. Therefore, although hospitalization of patients with pneumonia should be mainly based on clinical criteria, Fine's PSI classification could help physicians in making more rational decisions in this respect.

Risk stratification of early admission to the intensive care unit of patients with no major criteria of severe community-acquired pneumonia: development of an international prediction rule. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2009; 13:R54.

Abstract
Introduction To identify risk factors for early (< three days) intensive care unit (ICU) admission of patients hospitalised with community-acquired pneumonia (CAP) and not requiring immediate ICU admission, and to stratify the risk of ICU admission on days 1 to 3. Methods Using the original data from four North American and European prospective multicentre cohort studies of patients with CAP, we derived and validated a prediction rule for ICU admission on days 1 to 3 of emergency department (ED) presentation, for patients presenting with no obvious reason for immediate ICU admission (not requiring immediate respiratory or circulatory support). Results A total of 6560 patients were included (4593 and 1967 in the derivation and validation cohort, respectively), 303 (4.6%) of whom were admitted to an ICU on days 1 to 3. The Risk of Early Admission to ICU index (REA-ICU index) comprised 11 criteria independently associated with ICU admission: male gender, age younger than 80 years, comorbid conditions, respiratory rate of 30 breaths/minute or higher, heart rate of 125 beats/minute or higher, multilobar infiltrate or pleural effusion, white blood cell count less than 3 or 20 G/L or above, hypoxaemia (oxygen saturation < 90% or arterial partial pressure of oxygen (PaO2) < 60 mmHg), blood urea nitrogen of 11 mmol/L or higher, pH less than 7.35 and sodium less than 130 mEq/L. The REA-ICU index stratified patients into four risk classes with a risk of ICU admission on days 1 to 3 ranging from 0.7 to 31%. The area under the curve was 0.81 (95% confidence interval (CI) = 0.78 to 0.83) in the overall population. Conclusions The REA-ICU index accurately stratifies the risk of ICU admission on days 1 to 3 for patients presenting to the ED with CAP and no obvious indication for immediate ICU admission and therefore may assist orientation decisions.

Abstract
BACKGROUND AND OBJECTIVE This study examined the potential utility of outpatient parenteral antibiotic therapy (OPAT) as a means of reducing the excessive number of patients hospitalized with low-risk community-acquired pneumonia (CAP). METHODS A prospective feasibility study was conducted, in which a selection algorithm was applied to a cohort of patients admitted with suspected CAP, to identify a group in whom admission may have been prevented by the use of OPAT. Numbers of potentially suitable patients, inpatient bed days saved and frequency of adverse events that may have led to readmission were measured. RESULTS There were 118 inpatients treated with confirmed CAP during the study period, of whom 27 had low-risk disease (Pneumonia Severity Index grades I-III). Application of the selection algorithm identified eight (30% of those with low-risk disease) patients who were potentially suitable for OPAT, and this group commonly experienced adverse events during follow up which may have resulted in readmission to hospital. CONCLUSIONS In many hospitalized patients with CAP, outpatient therapy is precluded by either disease severity or active medical and psychosocial factors. This limits the role of OPAT as a tool for reducing the inpatient burden of CAP.
