Suspected Pneumonia (suspected + pneumonia)
Selected AbstractsPneumonia Versus Aspiration Pneumonitis in Nursing Home Residents: Prospective Application of a Clinical AlgorithmJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue 5 2005Joseph M. Mylotte MD Objectives: To prospectively evaluate a clinical algorithm for the diagnosis of pneumonitis and pneumonia in nursing home residents. Design: Prospective cohort study. Setting: Inpatient geriatrics unit. Participants: Nursing home residents admitted to the hospital with suspected pneumonia. Measurements: Identification of pneumonitis and pneumonia using the algorithm; medical record review and abstraction of clinical data; hospital outcome and length of stay. Results: One hundred seventy episodes of suspected pneumonia were screened with the algorithm and classified into four groups: 25% pneumonia, 28% aspiration pneumonitis of 24 hours or less duration, 12% aspiration pneumonitis of more than 24 hours' duration, and 35% an aspiration event without pneumonitis. Presenting symptoms and signs, laboratory tests, severity of illness measures, or serum C-reactive protein levels did not distinguish between the four groups. Those with an aspiration event without pneumonitis tended to be treated less often with antibiotic therapy after admission (P=.004) and after discharge (P=.01). Of those who survived, there was no significant difference in mean hospital length of stay between the four groups. There was no significant difference in the percentage of case fatality between the four groups, but those with aspiration pneumonitis of 24 hours or less duration and with an aspiration event without pneumonitis had a lower mortality than the other two groups. Conclusion: Distribution of episodes of suspected pneumonia by clinical category as determined using the algorithm was similar to that of the derivation study, as were case fatality rates in each category. These findings suggest that the algorithm may be useful for making the distinction between pneumonitis and pneumonia in nursing home residents; further studies are warranted. [source] Derivation of a Triage Algorithm for Chest Radiography of Community-acquired Pneumonia Patients in the Emergency DepartmentACADEMIC EMERGENCY MEDICINE, Issue 1 2008Demetrios N. Kyriacou MD Abstract Background:, Community-acquired pneumonia (CAP) accounts for 1.5 million emergency department (ED) patient visits in the United States each year. Objectives:, To derive an algorithm for the ED triage setting that facilitates rapid and accurate ordering of chest radiography (CXR) for CAP. Methods:, The authors conducted an ED-based retrospective matched case,control study using 100 radiographic confirmed CAP cases and 100 radiographic confirmed influenzalike illness (ILI) controls. Sensitivities and specificities of characteristics assessed in the triage setting were measured to discriminate CAP from ILI. The authors then used classification tree analysis to derive an algorithm that maximizes sensitivity and specificity for detecting patients with CAP in the ED triage setting. Results:, Temperature greater than 100.4°F (likelihood ratio = 4.39, 95% confidence interval [CI] = 2.04 to 9.45), heart rate greater than 110 beats/minute (likelihood ratio = 3.59, 95% CI = 1.82 to 7.10), and pulse oximetry less than 96% (likelihood ratio = 2.36, 95% CI = 1.32 to 4.20) were the strongest predictors of CAP. However, no single characteristic was adequately sensitive and specific to accurately discriminate CAP from ILI. A three-step algorithm (using optimum cut points for elevated temperature, tachycardia, and hypoxemia on room air pulse oximetry) was derived that is 70.8% sensitive (95% CI = 60.7% to 79.7%) and 79.1% specific (95% CI = 69.3% to 86.9%). Conclusions:, No single characteristic adequately discriminates CAP from ILI, but a derived clinical algorithm may detect most radiographic confirmed CAP patients in the triage setting. Prospective assessment of this algorithm will be needed to determine its effects on the care of ED patients with suspected pneumonia. [source] Emergency Department Operational Changes in Response to Pay-for-performance and Antibiotic Timing in PneumoniaACADEMIC EMERGENCY MEDICINE, Issue 6 2007Jesse M. Pines MD Background:The percentage of adult patients admitted with pneumonia who receive antibiotics within four hours of hospital arrival is publicly reported as a quality and pay-for-performance measure by the Department of Health and Human Services and is called PN-5b. Objectives:To determine attitudes among physician leaders at emergency medicine training programs toward using PN-5b as a quality measure for pay for performance, and to determine what operational changes academic emergency departments (EDs) have made to ensure early antibiotic administration for patients with pneumonia. Methods:The authors administered an online questionnaire to 129 chairpersons and medical directors of 135 academic ED training programs in the United States on attitudes toward performance measurement in pneumonia and changes that academic EDs have made in response to PN-5b; one response was sought from each institution. Respondents were identified through the Society for Academic Emergency Medicine Web site and e-mailed five times to maximize survey participation. Results:Ninety chairpersons and medical directors (70%) completed the survey; 47% were medical directors, 51% were chairpersons, and 2% were medical directors and chairpersons. Forty-five (50%) did not agree that PN-5b was an accurate quality measure, and 61 (69%) did not agree that pay for performance targeting this measure would lead to improved pneumonia care. The most common strategy to address PN-5b was to provide information to providers on the importance of early treatment with antibiotics (n = 63; 70%). For patients with suspected pneumonia, 46 (51%) automate chest radiograph (CXR) ordering at triage, 37 (41%) prioritize patients with suspected pneumonia, and 33 (37%) administer antibiotics before obtaining CXR results. Overall ED changes include improved turnaround time for CXR (n= 33; 37%), prioritized CXRs over other radiographs (n= 13; 14%), and improved inpatient bed availability (n= 12; 13%). Of 13 strategies identified to improve PN-5b, the median number that programs have implemented is five (interquartile range, 5,7). All sites reported engaging in at least three operational changes to address PN-5b. Conclusions:All EDs in this study have addressed early antibiotic administration with multiple operational changes despite mixed sentiment that these changes will improve care. Future research is needed to measure the impact of pay-for-performance initiatives. [source] Clinical Predictors of Occult Pneumonia in the Febrile ChildACADEMIC EMERGENCY MEDICINE, Issue 3 2007Charles G. Murphy MD Background: The utility of chest radiographs (CXRs) for detecting occult pneumonia (OP) among pediatric patients without lower respiratory tract signs has been previously studied, but no predictors other than white blood cell count (WBC) and height of fever have been investigated. Objectives: To identify predictors of OP in pediatric patients in the postconjugate pneumococcal vaccination era. Methods: This was a retrospective cross sectional study that was conducted in a large urban pediatric hospital. Physician records of emergency department (ED) patients of age 10 years or less who presented with fever (,38°C) and had a CXR obtained for suspected pneumonia were reviewed. Patients were classified into two groups: "signs of pneumonia" and "no signs of pneumonia" on the basis of the presence or absence of respiratory distress, tachypnea, or lower respiratory tract findings. Occult pneumonia was defined as radiographic pneumonia in a patient without signs of pneumonia. Results: Two thousand one hundred twenty-eight patients were studied. Among patients categorized as having no signs of pneumonia (n = 1,084), 5.3% (95% CI = 4.0% to 6.8%) had OP. Presence of cough and longer duration of cough (greater than 10 days) had positive likelihood ratios (LR+) of 1.24 (95% CI = 1.15 to 1.33) and 2.25 (95% CI = 1.21 to 4.20), respectively. Absence of cough had a negative likelihood ratio (LR,) of 0.19 (95% CI = 0.05 to 0.75). The likelihood of OP increased with increasing duration of fever (LR+ for more than three days and more than five days of fever, respectively: 1.62; 95% CI = 1.13 to 2.31 and 2.24; 95% CI = 1.35 to 3.71). When obtained (56% of patients), WBC was a predictor of OP, with a LR+ of 1.76 (95% CI = 1.40 to 2.22) and 2.17 (95% CI = 1.58 to 2.96) for WBC of >15,000/mm3 and >20,000/mm3, respectively. Conclusions: Occult pneumonia was found in 5.3% of patients with fever and no lower respiratory tract findings, tachypnea, or respiratory distress. There is limited utility in obtaining a CXR in febrile children without cough. The likelihood of pneumonia increased with longer duration of cough or fever or in the presence of leukocytosis.
