Crb65

Severe community-acquired pneumonia and hospital-acquired pneumonia are common infectious diseases in Germany. They are associated with high mortality especially in the old and multimorbid patient and are thus a challenge in daily clinical practice. While the CRB65 is a thoroughly validated score for risk stratification in community-acquired pneumonia, there is no comparable score for hospital-acquired pneumonia yet. Early initiation of adequate antibiotic treatment is essential for a positive outcome. Hospital-acquired pneumonia is more often associated with multidrug-resistant bacteria, which should be considered in the choice of initial treatment especially if the patient can be considered a member of a risk group...

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...

BACKGROUND: The aim of this meta-analysis was to determine if severity assessment tools can be used to guide decisions regarding intensive care unit (ICU) admission of patients with community-acquired pneumonia. METHODS: A search of PUBMED and EMBASE (1980-2009) was conducted to identify studies reporting pneumonia severity scores and prediction of ICU admission. Two reviewers independently collected data and assessed study quality. Performance characteristics were pooled using a random-effects model...

OBJECTIVE: To develop and validate a clinical rule to predict treatment failure in middle-aged and elderly patients suffering from community-acquired pneumonia (CAP) in China, and to compare it with other prognostic rules. METHODS: Data of 58 variables affiliated to 6 aspects, including demographics, underlaying diseases, previous status, complications, symptoms, signs and laboratory examination results from the CAP patients aged≥45 years admitted to the respiratory departments in three university affiliated hospitals between December 17, 2006 and December 22, 2008 were enrolled prospectively and then validated in two groups to create a derivation cohort with 75% of the patients for rule development and an internal validation cohort with the other 25% for internal test...

BACKGROUND AND OBJECTIVE: The CRB65 score, a risk stratification method validated for use in community-acquired pneumonia, has recently been shown to have utility in acute exacerbations of COPD (AECOPD). The objective of this study was to independently validate the CRB65 score as a predictor of mortality in patients who required hospital admission with AECOPD. METHODS: The medical records of patients admitted to Wellington Hospital with AECOPD during a 12-month period from June 2006 were reviewed...

INTRODUCTION: International guidelines recommend a severity-based approach to management in community-acquired pneumonia. CURB65, CRB65 and the Pneumonia Severity Index (PSI) are the most widely recommended severity scores. The aim of this study was to compare the performance characteristics of these scores for predicting mortality in community-acquired pneumonia. METHODS: A systematic review and meta-analysis was conducted according to MOOSE (meta-analysis of observational studies in epidemiology) guidelines...

OBJECTIVES: Guidelines recommend dual-therapy consisting of a beta-lactam/macrolide (BLM) for hospitalized patients with community-acquired pneumonia. Nevertheless, the superiority over beta-lactam-monotherapy (BL) remains unproven. METHODS: Analyses from an observational study initiated by the German competence network CAPNETZ were performed. RESULTS: One thousand eight hundred and fifty-four patients were treated with either BL (49.0%) or BLM (51...

BACKGROUND: The aim of this study was to identify key factors on admission predicting the development of complicated parapneumonic effusion or empyema in patients admitted with community-acquired pneumonia. METHODS: A prospective observational study of patients admitted with community-acquired pneumonia in NHS Lothian, UK, was conducted. Multivariate regression analyses were used to evaluate factors that could predict the development of complicated parapneumonic effusion or empyema, including admission demographics, clinical features, laboratory tests and pneumonia-specific (Pneumonia Severity Index (PSI), CURB65 (New onset confusion, urea >7 mmol/l, Respiratory rate > or = 30 breaths/min, Systolic blood pressure < 90 mm Hg and/or diastolic blood pressure < or = 60 mm Hg and age > or = 65 years) and CRB65 (New onset confusion, Respiratory rate > or = 30 breaths/min, Systolic blood pressure <90 mm Hg and/or diastolic blood pressure < or = 60 mm Hg and age > or = 65 years)) and generic sepsis scoring systems (APACHE II (Acute Physiology and Chronic Health Evaluation II), SEWS (standardised early warning score) and systemic inflammatory response syndrome (SIRS))...

BACKGROUND: Prognostic scales provide a useful tool to predict mortality in community-acquired pneumonia (CAP). However, the inflammatory response of the host, crucial in resolution and outcome, is not included in the prognostic scales. METHODS: The aim of this study was to investigate whether information about the initial inflammatory cytokine profile and markers increases the accuracy of prognostic scales to predict 30-day mortality. To this aim, a prospective cohort study in two tertiary care hospitals was designed...

INTRODUCTION: Admission blood pressure (BP) assessment is a central component of severity assessment for community acquired pneumonia. The aim of this study was to establish which readily available haemodynamic measure on admission is most useful for predicting severity in patients admitted with community acquired pneumonia. METHODS: A prospective observational study of patients admitted with community acquired pneumonia was conducted in Edinburgh, UK. The measurements compared were systolic and diastolic BP, mean arterial pressure and pulse pressure...

SETTING: Aga Khan University Hospital, Karachi, Pakistan. OBJECTIVE: To prospectively compare 30-day mortality with CURB65 and CRB65 scores and the three mortality risk groups (low, intermediate and high) based on these scores in hospitalised patients with community-acquired pneumonia (CAP). DESIGN: Longitudinal observational cohort study of adult in-patients fulfilling the definition of CAP between October 2006 and May 2007. RESULTS: A total of 137 patients was included...

In patients with community-acquired pneumonia (CAP) prediction rules based on individual predicted mortalities are frequently used to support decision-making for in-patient vs. outpatient management. We studied the accuracy and the need for recalibration of three risk prediction scores in a tertiary-care University hospital emergency-department setting in Switzerland. We pooled data from patients with CAP enrolled in two randomized controlled trials. We compared expected mortality from the original pneumonia severity index (PSI), CURB65 and CRB65 scores against observed mortality (calibration) and recalibrated the scores by fitting the intercept alpha and the calibration slope beta from our calibration model...

OBJECTIVE: To compare the predictive accuracy for 30-day mortality of the CURB65 score adopted by the British Thoracic Society and the simpler CRB65 score to APACHE (acute physiology and chronic health evaluation) II in patients with methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. DESIGN: A retrospective, single-center, observational cohort study. SETTING: Barnes-Jewish Hospital, a 1,200-bed urban teaching hospital. PATIENTS: Adult patients requiring hospitalization identified to have MRSA pneumonia...

BACKGROUND: Community-acquired pneumonia (CAP) is a leading infectious cause of death throughout the world, including Hong Kong. AIM: To compare the ability of three validated prediction rules for CAP to predict mortality in Hong Kong: the 20 variable Pneumonia Severity Index (PSI), the 6-point CURB65 scale adopted by the British Thoracic Society and the simpler CRB65. METHODS: A prospective observational study of 1016 consecutive inpatients with CAP (583 men, mean (SD) age 72 (17) years) was performed in a university hospital in the New Territories of Hong Kong in 2004...

BACKGROUND: The performance of CURB65 in predicting mortality in community-acquired pneumonia (CAP) has been tested in two large observational studies. However, it has not been tested against generic sepsis and early warning scores, which are increasingly being advocated for identification of high-risk patients in acute medical wards. METHOD: A retrospective analysis was performed of data prospectively collected for a CAP quality improvement study. The ability to stratify mortality and performance characteristics (sensitivity, specificity, positive predictive value, negative predictive value and area under the receiver operating curve) were calculated for stratifications of CURB65, CRB65, the systemic inflammatory response syndrome (SIRS) criteria and the standardised early warning score (SEWS)...
