Diagnostic Performance of Plasma SP-D, KL-6, and CC16 in Acutely Hospitalised Patients Suspected of Having Community-Acquired Pneumonia-A Diagnostic Accuracy Study. Diagnostics (Basel) 2024; 14:1283. [PMID: 38928698 PMCID: PMC11202779 DOI: 10.3390/diagnostics14121283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Revised: 06/10/2024] [Accepted: 06/12/2024] [Indexed: 06/28/2024] Open
Abstract
Community-acquired pneumonia is a common cause of acute hospitalisation. Identifying patients with community-acquired pneumonia among patients suspected of having the disease can be a challenge, which causes unnecessary antibiotic treatment. We investigated whether the circulatory pulmonary injury markers surfactant protein D (SP-D), Krebs von den Lungen-6 (KL-6), and Club cell protein 16 (CC16) could help identify patients with community-acquired pneumonia upon acute admission. In this multi-centre diagnostic accuracy study, SP-D, KL-6, and CC16 were quantified in plasma samples from acutely hospitalised patients with provisional diagnoses of community-acquired pneumonia. The area under the receiver operator characteristics curve (AUC) was calculated for each marker against the following outcomes: patients' final diagnoses regarding community-acquired pneumonia assigned by an expert panel, and pneumonic findings on chest CTs. Plasma samples from 339 patients were analysed. The prevalence of community-acquired pneumonia was 63%. AUCs for each marker against both final diagnoses and chest CT diagnoses ranged between 0.50 and 0.56. Thus, SP-D, KL-6, and CC16 demonstrated poor diagnostic performance for community-acquired pneumonia in acutely hospitalised patients. Our findings indicate that the markers cannot readily assist physicians in confirming or ruling out community-acquired pneumonia.

Development of Patient Safety Measures to Identify Inappropriate Diagnosis of Common Infections. Clin Infect Dis 2024; 78:1403-1411. [PMID: 38298158 PMCID: PMC11175682 DOI: 10.1093/cid/ciae044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 12/28/2023] [Accepted: 01/26/2024] [Indexed: 02/02/2024] Open
Abstract
BACKGROUND Inappropriate diagnosis of infections results in antibiotic overuse and may delay diagnosis of underlying conditions. Here we describe the development and characteristics of 2 safety measures of inappropriate diagnosis of urinary tract infection (UTI) and community-acquired pneumonia (CAP), the most common inpatient infections on general medicine services. METHODS Measures were developed from guidelines and literature and adapted based on data from patients hospitalized with UTI and CAP in 49 Michigan hospitals and feedback from end-users, a technical expert panel (TEP), and a patient focus group. Each measure was assessed for reliability, validity, feasibility, and usability. RESULTS Two measures, now endorsed by the National Quality Forum (NQF), were developed. Measure reliability (derived from 24 483 patients) was excellent (0.90 for UTI; 0.91 for CAP). Both measures had strong validity demonstrated through (a) face validity by hospital users, the TEPs, and patient focus group, (b) implicit case review (ĸ 0.72 for UTI; ĸ 0.72 for CAP), and (c) rare case misclassification (4% for UTI; 0% for CAP) due to data errors (<2% for UTI; 6.3% for CAP). Measure implementation through hospital peer comparison in Michigan hospitals (2017 to 2020) demonstrated significant decreases in inappropriate diagnosis of UTI and CAP (37% and 32%, respectively, P < .001), supporting usability. CONCLUSIONS We developed highly reliable, valid, and usable measures of inappropriate diagnosis of UTI and CAP for hospitalized patients. Hospitals seeking to improve diagnostic safety, antibiotic use, and patient care should consider using these measures to reduce inappropriate diagnosis of CAP and UTI.

Community-acquired pneumonia: use of clinical characteristics of acutely admitted patients for the development of a diagnostic model - a cross-sectional multicentre study. BMJ Open 2024; 14:e079123. [PMID: 38816044 PMCID: PMC11141191 DOI: 10.1136/bmjopen-2023-079123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 05/20/2024] [Indexed: 06/01/2024] Open
Abstract
OBJECTIVES This study aimed to describe the clinical characteristics of adults with suspected acute community-acquired pneumonia (CAP) on hospitalisation, evaluate their prediction performance for CAP and compare the performance of the model to the initial assessment of the physician. DESIGN Cross-sectional, multicentre study. SETTING The data originated from the INfectious DisEases in Emergency Departments study and were collected prospectively from patient interviews and medical records. The study included four Danish medical emergency departments (EDs) and was conducted between 1 March 2021 and 28 February 2022. PARTICIPANTS A total of 954 patients admitted with suspected infection were included in the study. PRIMARY AND SECONDARY OUTCOME The primary outcome was CAP diagnosis assessed by an expert panel. RESULTS According to expert evaluation, CAP had a 28% prevalence. 13 diagnostic predictors were identified using least absolute shrinkage and selection operator regression to build the prediction model: dyspnoea, expectoration, cough, common cold, malaise, chest pain, respiratory rate (>20 breaths/min), oxygen saturation (<96%), abnormal chest auscultation, leucocytes (<3.5×109/L or >8.8×109/L) and neutrophils (>7.5×109/L). C reactive protein (<20 mg/L) and having no previous event of CAP contributed negatively to the final model. The predictors yielded good prediction performance for CAP with an area under the receiver-operator characteristic curve (AUC) of 0.85 (CI 0.77 to 0.92). However, the initial diagnosis made by the ED physician performed better, with an AUC of 0.86 (CI 84% to 89%). CONCLUSION Typical respiratory symptoms combined with abnormal vital signs and elevated infection biomarkers were predictors for CAP on admission to an ED. The clinical value of the prediction model is questionable in our setting as it does not outperform the clinician's assessment. Further studies that add novel diagnostic tools and use imaging or serological markers are needed to improve a model that would help diagnose CAP in an ED setting more accurately. TRIAL REGISTRATION NUMBER NCT04681963.

Abstract
Pneumonia is split into 3 diagnostic categories: community-acquired pneumonia (CAP), health care-associated pneumonia, and ventilator-associated pneumonia. This classification scheme is driven not only by the location of infection onset but also by the predominant associated causal microorganisms. Pneumonia is diagnosed in over 1.5 million US emergency department visits annually (1.2% of all visits), and most pneumonia diagnosed by emergency physicians is CAP.

Abstract
BACKGROUND Aspiration pneumonia in older adults is increasingly common, with a high care burden and morbidity. However, clinical competencies in its management have not been developed, and healthcare professionals struggle on how to care for these patients with multimodal treatment needs. Therefore, we conducted a scoping review to investigate what is known about the desired clinical competencies for the management of older adults with aspiration pneumonia, to utilise in clinical practice, education, and future research. METHODS First, we defined aspiration pneumonia according to a preliminary search. We then searched the literature on MEDLINE and CINAHL, focusing on studies involving patients aged 65 years old and older diagnosed with aspiration pneumonia. All settings were included, with the exception of intensive care units. Publication dates were limited to January 2011 to July 2022 and languages to English and Japanese. The extracted data were used to refine the preliminary competency framework developed by the Japan Aspiration pneumonia inter-Professional team Educational Program (JAPEP) in preparation of this study. RESULTS Ninety-nine studies were included. Following data extraction from these studies, 3 competencies were renamed, and 3 new competencies were added, to create a list of 12 competencies. These were Diagnosis, Treatment, Swallow Assessment, Underlying condition management, Nutrition, Oral management, Rehabilitation, Multidisciplinary team, Decision making, Prevention, Prognosis, and Palliative care. CONCLUSIONS Our scoping review identified 12 clinical competencies required in the management of older adults with aspiration pneumonia, outlined in the phrase 'Diagnose, Treat and SUPPORT'. We encourage healthcare professionals to share these competencies as a team to identify areas of unmet need and improve their patient care, with an emphasis on supportive care.

Abstract
BACKGROUND High-quality research studies in older adults are needed. Unfortunately, the accuracy of chart review data in older adult patients has been called into question by previous studies. Little is known on this topic in patients with suspected pneumonia, a disease with 500,000 annual older adult U.S. emergency department (ED) visits that presents a diagnostic challenge to ED physicians. The study objective was to compare direct interview and chart abstraction as data sources. METHODS We present a preplanned secondary analysis of a prospective, observational cohort of ED patients ≥65 years of age with suspected pneumonia in two Midwest EDs. We describe the agreement between chart review and a criterion standard of prospective direct patient survey (symptoms) or direct physician survey (examination findings). Data were collected by chart review and from the patient and treating physician by survey. RESULTS The larger study enrolled 135 older adults; 134 with complete symptom data and 129 with complete examination data were included in this analysis. Pneumonia symptoms (confusion, malaise, rapid breathing, any cough, new/worse cough, any sputum production, change to sputum) had agreement between patient/legally authorized representative survey and chart review ranging from 47.8% (malaise) to 80.6% (confusion). All examination findings (rales, rhonchi, wheeze) had percent agreement between physician survey and chart review of ≥80%. However, all kappas except wheezing were less than 0.60, indicating weak agreement. CONCLUSIONS Both patient symptoms and examination findings demonstrated discrepancies between chart review and direct survey with larger discrepancies in symptoms reported. Researchers should consider these potential discrepancies during study design and data interpretation.

Abstract
BACKGROUND Denmark has a low level of antimicrobial resistance (AMR). Patients hospitalized with suspected infection often present with unspecific symptoms. This challenges the physician between using narrow-spectrum antibiotics in accordance with guidelines or broad-spectrum antibiotics to compensate for diagnostic uncertainty. The aim of this study was to investigate adherence to a restrictive antibiotic guideline for the most common infection in emergency departments (EDs), namely community-acquired pneumonia (CAP). METHOD This multicenter descriptive cross-sectional study included adults admitted to Danish EDs with a suspected infection. Data were collected prospectively from medical records. RESULTS We included 954 patients in the analysis. The most prescribed antibiotics were penicillin with beta-lactamase inhibitor at 4 h (307 (32.2%)), 48 h (289 (30.3%)), and day 5 after admission (218 (22.9%)). The empirical antibiotic treatment guidelines for CAP were followed for 126 (31.3%) of the CAP patients. At 4 h, antibiotics were administered intravenously to 244 (60.7%) of the CAP patients. At day 5, 218 (54.4%) received oral antibiotics. CONCLUSION Adherence to CAP guidelines was poor. In a country with a restrictive antibiotic policy, infections are commonly treated with broad-spectrum antibiotics against recommendations.

Abstract
BACKGROUND Rapid and accurate detection of pathogens is needed in community-acquired pneumonia (CAP) to enable appropriate antibiotics and to slow the development of antibiotic resistance. We aimed to compare the effect of point-of-care (POC) polymerase chain reaction (PCR) detection of respiratory pathogens added to standard care with standard care only (SCO) on antibiotic prescriptions after acute hospital admission. METHODS AND FINDINGS We performed a superiority, parallel-group, open-label, multicentre, randomised controlled trial (RCT) in 3 Danish medical emergency departments (EDs) from March 2021 to February 2022. Adults acutely admitted with suspected CAP during the daytime on weekdays were included and randomly assigned (1:1) to POC-PCR (The Biofire FilmArray Pneumonia Panel plus added to standard care) or SCO (routine culture and, if requested by the attending physician, target-specific PCR) analysis of respiratory samples. We randomly assigned 294 patients with successfully collected samples (tracheal secretion 78.4% or expectorated sputum 21.6%) to POC-PCR (n = 148, 50.4%) or SCO (146, 49.6%). Patients and investigators owning the data were blinded to the allocation and test results. Outcome adjudicators and clinical staff at the ED were not blinded to allocation and test results but were together with the statistician, blinded to data management and analysis. Laboratory staff performing standard care analyses was blinded to allocation. The study coordinator was not blinded. Intention-to-treat and per protocol analysis were performed using logistic regression with Huber-White clustered standard errors for the prescription of antibiotic treatment. Loss to follow-up comprises 3 patients in the POC-PCR (2%) and none in the SCO group. Intention-to-treat analysis showed no difference in the primary outcome of prescriptions of no or narrow-spectrum antibiotics at 4 h after admission for the POC-PCR (n = 91, 62.8%) odds ratio (OR) 1.13; (95% confidence interval (CI) [0.96, 1.34] p = 0.134) and SCO (n = 87, 59.6%). Secondary outcomes showed that prescriptions were significantly more targeted at 4-h OR 5.68; (95% CI [2.49, 12.94] p < 0.001) and 48-h OR 4.20; (95% CI [1.87, 9.40] p < 0.001) and more adequate at 48-h OR 2.11; (95% CI [1.23, 3.61] p = 0.006) and on day 5 in the POC-PCR group OR 1.40; (95% CI [1.18, 1.66] p < 0.001). There was no difference between the groups in relation to intensive care unit (ICU) admissions OR 0.54; (95% CI [0.10, 2.91] p = 0.475), readmission within 30 days OR 0.90; (95% CI [0.43, 1.86] p = 0.787), length of stay (LOS) IRR 0.82; (95% CI [0.63, 1.07] p = 0.164), 30 days mortality OR 1.24; (95% CI [0.32, 4.82] p = 0.749), and in-hospital mortality OR 0.98; (95% CI [0.19, 5.06] p = 0.986). CONCLUSIONS In a setting with an already restrictive use of antibiotics, adding POC-PCR to the diagnostic setup did not increase the number of patients treated with narrow-spectrum or without antibiotics. POC-PCR may result in a more targeted and adequate use of antibiotics. A significant study limitation was the concurrent Coronavirus Disease 2019 (COVID-19) pandemic resulting in an unusually low transmission of respiratory virus.

Abstract
This study aimed to evaluate the effectiveness of various scoring systems in predicting in-hospital mortality for COVID-19 patients admitted to the internal medicine ward. We conducted a prospective collection of clinical data from patients admitted to the Internal Medicine Unit at Santa Maria Nuova Hospital in Florence, Italy, with confirmed pneumonia caused by SARS-CoV-2. We calculated three scoring systems: the CALL score, the PREDI-CO score, and the COVID-19 in-hospital Mortality Risk Score (COVID-19 MRS). The primary endpoint was in-hospital mortality. : A total of 681 patients were enrolled in the study, with a mean age of 68.8 ± 16.1 years, and 54.8% of them were male. Non-survivors had significantly higher scores in all prognostic systems compared to survivors (MRS: 13 [12- 15] vs. 10 [8-12]; CALL: 12 [10-12] vs. 9 [7-11]; PREDI-CO: 4 [3-6] vs. 2 [1-4]; all p<0.001). The receiver operating characteristic (ROC) analysis yielded the following area under the curve (AUC) values: MRS 0.85, CALL 0.78, PREDI-CO 0.77. The addition of Delirium and IL6 to the scoring systems improved their discriminative ability, resulting in AUC values of 0.92 for MRS, 0.87 for CALL, and 0.84 for PREDI-CO. The mortality rate increased significantly across increasing quartiles (p<0.001). In conclusion the COVID-19 in-hospital Mortality Risk Score (MRS) demonstrated reasonable prognostic stratification for patients admitted to the internal medicine ward with SARS-CoV-2-induced pneumonia. The inclusion of Delirium and IL6 as additional prognostic indicators in the scoring systems enhanced their predictive performance, specifically in determining in-hospital mortality among COVID-19 patients.

Organizational Benefits of Ultra-Low-Dose Chest CT Compared to Chest Radiography in the Emergency Department for the Diagnostic Workup of Community-Acquired Pneumonia: A Real-Life Retrospective Analysis. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1508. [PMID: 37763627 PMCID: PMC10532772 DOI: 10.3390/medicina59091508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 08/01/2023] [Accepted: 08/18/2023] [Indexed: 09/29/2023]
Abstract
Background and Objectives: Chest radiography remains the most frequently used examination in emergency departments (ED) for the diagnosis of community-acquired pneumonia (CAP), despite its poor diagnostic accuracy compared with ultra-low-dose (ULD) chest computed tomography (CT). However, although ULD CT appears to be an attractive alternative to radiography, its organizational impact in ED remains unknown. Our objective was to compare the relevant timepoints in ED management of CT and chest radiography. Materials and Methods: We conducted a retrospective study in two ED of a University Hospital including consecutive patients consulting for a CAP between 1 March 2019 and 29 February 2020 to assess the organizational benefits of ULD chest CT and chest radiography (length of stay (LOS) in the ED, time of clinical decision after imaging). Overlap weights (OW) were used to reduce covariate imbalance between groups. Results: Chest radiography was performed for 1476 patients (mean age: 76 years [63; 86]; 55% men) and ULD chest CT for 133 patients (mean age: 71 [57; 83]; 53% men). In the weighted population with OW, ULD chest CT did not significantly alter the ED LOS compared with chest radiography (11.7 to 12.2; MR 0.96 [0.85; 1.09]), although it did significantly reduce clinical decision time (6.9 and 9.5 h; MR 0.73 [0.59; 0.89]). Conclusion: There is real-life evidence that a strategy with ULD chest CT can be considered to be a relevant approach to replace chest radiography as part of the diagnostic workup for CAP in the ED without increasing ED LOS.

Abstract
Introduction Whether a delayed diagnosis of community-acquired pneumonia (CAP) in the emergency department (ED) is associated with worse outcome is uncertain. We sought factors associated with a delayed diagnosis of CAP in the ED and those associated with in-hospital mortality. Methods Retrospective study including all inpatients admitted to an ED (Dijon University Hospital, France) from 1 January to 31 December 2019, and hospitalized with a diagnosis of CAP. Patients diagnosed with CAP in the ED (n = 361, early diagnosis) were compared with those diagnosed later, in the hospital ward, after the ED visit (n = 74, delayed diagnosis). Demographic, clinical, biological and radiological data were collected upon admission to the ED, as well as administered therapies and outcomes including in-hospital mortality. Results 435 inpatients were included: 361 (83%) with an early and 74 (17%) with a delayed diagnosis. The latter less frequently required oxygen (54 vs. 77%; p < 0.001) and were less likely to have a quick-SOFA score ≥ 2 (20 vs. 32%; p = 0.056). Absence of chronic neurocognitive disorders, of dyspnea, and of radiological signs of pneumonia were independently associated with a delayed diagnosis. Patients with a delayed diagnosis less frequently received antibiotics in the ED (34 vs. 75%; p < 0.001). However, a delayed diagnosis was not associated with in-hospital mortality after adjusting on initial severity. Conclusion Delayed diagnosis of pneumonia was associated with a less severe clinical presentation, lack of obvious signs of pneumonia on chest X-ray, and delayed antibiotics initiation, but was not associated with worse outcome.

Abstract
To test the prognostic performance of different scores, both specifically designed for patients with COVID-19 and generic, in predicting in-hospital mortality and the need for mechanical ventilation (MV). We retrospectively collected clinical data of patients admitted to the Emergency Department of the University Hospital AOU Careggi, Florence, Italy, between February 2020 and January 2021, with a confirmed infection by SARS-CoV2. We calculated the following scores: Sequential Organ Failure Assessment (SOFA) score, CALL score, 4C Mortality score, QUICK score, CURB-65 and MuLBSTA score. The end-points were in-hospital mortality and the need for MV. We included 1208 patients, mean age 60 ± 17 years, 57% male sex. Compared to survivors, non-survivors showed significantly higher values of all the prognostic scores (4C: 13 [10-15] vs 8 [4-10]; CALL: 11 [10-12] vs 9 [7-11]; QUICK: 4 [1-6] vs 0 [0-3]; SOFA: 5 [4-6] vs 4 [4-5]; CURB: 2 [1-3] vs 1 [0-1]; MuLBSTA: 11 [9-13] vs 9 [7-11], all p < 0.001). Discriminative ability evaluated by the Receiver Operating Curve analysis showed the following values of the Area under the Curve: 0.83 for 4C, 0.74 for CALL, 0.70 for QUICK, 0.68 for SOFA, 0.76 for CURB and 0.64 for MuLBSTA. The mortality rate significantly increased in increasing quartiles of 4C and CALL score (respectively, 2, 8, 24 and 54% for the 4C score and 1, 17, 33 and 68% for the CALL score, both p < 0.001). 4C and CALL score allowed an early and good prognostic stratification of patients admitted for pneumonia induced by SARS-CoV2.

Abstract
In older adults, community-acquired pneumonia (CAP) is often aspiration-related. However, as aspiration pneumonia (AP) lacks clear diagnostic criteria, the reported prevalence and clinical management vary greatly. We investigated what clinical factors appeared to influence the diagnosis of AP and non-AP in a clinical setting and reconsidered a more clinically relevant approach. Medical records of patients aged ≥75 years admitted with CAP were reviewed retrospectively. A total of 803 patients (134 APs and 669 non-APs) were included. The AP group had significantly higher rates of frailty, had higher SARC-F scores, resided in institutions, had neurologic conditions, previous pneumonia diagnoses, known dysphagia, and were more likely to present with vomiting or coughing on food. Nil by mouth orders, speech therapist referrals, and broad-spectrum antibiotics were significantly more common, while computed tomography scans and blood cultures were rarely performed; alternative diagnoses, such as cancer and pulmonary embolism, were detected significantly less. AP is diagnosed more commonly in frail patients, while aspiration is the underlying aetiology in most types of pneumonia. A presumptive diagnosis of AP may deny patients necessary investigation and management. We suggest a paradigm shift in the way we approach older patients with CAP; rather than trying to differentiate AP and non-AP, it would be more clinically relevant to recognise all pneumonia as just pneumonia, and assess their swallowing functions, causative organisms, and investigate alternative diagnoses or underlying causes of dysphagia. This will enable appropriate clinical management.

Abstract
Background A comprehensive study of respiratory pathogens was conducted in an area with a low prevalence of COVID-19 among the adults quarantined at a tertiary hospital. Methods From March to May 2020, 201 patients suspected lower respiratory tract infection (LRTI) were surveyed for etiologies by multiplex polymerase chain reaction (PCR: FilmArray TM Respiratory Panel) test combination with cultural method, viral antigen detection and serologic surveys. Results Total 201 patients tested with FilmArray TM Respiratory Panel were enrolled, of which 68.2% had sputum bacterial culture, 86.1% had pneumococcus and Legionella urine antigen test. Their median age was 72.0 year-old with multiple comorbidities, and 11.4% were nursing home residents. Bacteria accounted for 59.7% of identified pathogens. Atypical pathogens were identified in 31.3% of total pathogens, of which viruses accounted for 23.9%. In comparison to patients with bacterial infection, patients with atypical pathogens were younger (median= 77.2 vs 67.1, years, P = 0.017) and had shorter length of hospital (8.0 vs 4.5, days, P = 0.007). Conclusions Patients with LRTI caused by atypical pathogens was indistinguishable from those with bacterial pathogens by clinical manifestations or biomarkers. Multiplex PCR providing rapid diagnosis of atypical pathogens enhance patient care and decision making when rate of sputum culture sampling was low in quarantine ward during pandemic.

Abstract
INTRODUCTION Pneumonia is a leading cause of mortality and a common indication for antibiotic in elderly patients. However, its diagnosis is often inaccurate. We aim to compare the diagnostic accuracy, the clinical and cost outcomes and the use of antibiotics associated with three imaging strategies in patients >65 years old with suspected pneumonia in the emergency room (ER): chest X-ray (CXR, standard of care), low-dose CT scan (LDCT) or lung ultrasonography (LUS). METHODS AND ANALYSIS This is a multicentre randomised superiority clinical trial with three parallel arms. Patients will be allocated in the ER to a diagnostic strategy based on either CXR, LDCT or LUS. All three imaging modalities will be performed but the results of two of them will be masked during 5 days to the patients, the physicians in charge of the patients and the investigators according to random allocation. The primary objective is to compare the accuracy of LDCT versus CXR-based strategies. As secondary objectives, antibiotics prescription, clinical and cost outcomes will be compared, and the same analyses repeated to compare the LUS and CXR strategies. The reference diagnosis will be established a posteriori by a panel of experts. Based on a previous study, we expect an improvement of 16% of the accuracy of pneumonia diagnosis using LDCT instead of CXR. Under this assumption, and accounting for 10% of drop-out, the enrolment of 495 patients is needed to prove the superiority of LDCT over CRX (alpha error=0.05, beta error=0.10).

Abstract
Hospitalized patients with SARS-CoV-2 infection (COVID-19) often receive antibiotics for suspected bacterial coinfection. We estimated the incidence of bacterial coinfection and secondary infection in COVID-19 using clinical diagnoses to determine how frequently antibiotics are administered when bacterial infection is absent. We performed a retrospective cohort study of inpatients with COVID-19 present on admission to hospitals in the Premier Healthcare Database between April and June 2020. Bacterial infections were defined using ICD-10-CM diagnosis codes and associated “present on admission” coding. Coinfections were defined by bacterial infection present on admission, while secondary infections were defined by bacterial infection that developed after admission. Coinfection and secondary infection were not mutually exclusive. A total of 18.5% of 64,961 COVID-19 patients (n = 12,040) presented with bacterial infection at admission, 3.8% (n = 2,506) developed secondary infection after admission, and 0.9% (n = 574) had both; 76.3% (n = 49,551) received an antibiotic while hospitalized, including 71% of patients who had no diagnosis of bacterial infection. Secondary bacterial infection occurred in 5.7% of patients receiving steroids in the first 2 days of hospitalization, 9.9% receiving tocilizumab in the first 2 days of hospitalization, and 10.3% of patients receiving both. After adjusting for patient and hospital characteristics, bacterial coinfection (adjusted relative risk [aRR], 1.15; 95% confidence interval [CI], 1.11 to 1.20) and secondary infection (aRR 1.93; 95% CI, 1.82 to 2.04) were both independently associated with increased mortality. Although 1 in 5 inpatients with COVID-19 presents with bacterial infection, secondary infections in the hospital are uncommon. Most inpatients with COVID-19 receive antibiotic therapy, including 71% of those not diagnosed with bacterial infection.

Abstract
BACKGROUND The major obstacle in prescribing an appropriate and targeted antibiotic treatment is insufficient knowledge concerning whether the patient has a bacterial infection, where the focus of infection is and which bacteria are the agents of the infection. A prerequisite for the appropriate use of antibiotics is timely access to accurate diagnostics such as point-of-care (POC) testing.The study aims to evaluate diagnostic tools and working methods that support a prompt and accurate diagnosis of hospitalised patients suspected of an acute infection. We will focus on the most common acute infections: community-acquired pneumonia (CAP) and acute pyelonephritis (APN). The objectives are to investigate (1) patient characteristics and treatment trajectory of the different acute infections, (2) diagnostic and prognostic accuracy of infection markers, (3) diagnostic accuracy of POC urine flow cytometry on diagnosing and excluding bacteriuria, (4) how effective the addition of POC analysis of sputum to the diagnostic set-up for CAP is on antibiotic prescriptions, (5) diagnostic accuracy of POC ultrasound and ultralow dose (ULD) computerized tomography (CT) on diagnosing CAP, (6) diagnostic accuracy of specialist ultrasound on diagnosing APN, (7) diagnostic accuracy of POC ultrasound in diagnosing hydronephrosis in patients suspected of APN. METHODS AND ANALYSIS It is a multifaceted multicentre diagnostic study, including 1000 adults admitted with suspicion of an acute infection. Participants will, within the first 24 hours of admission, undergo additional diagnostic tests including infection markers, POC urine flow cytometry, POC analysis of sputum, POC and specialist ultrasound, and ULDCT. The primary reference standard is an assigned diagnosis determined by a panel of experts.

[PMID: 33249675 PMCID: PMC10561323 DOI: 10.1111/acem.14183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 10/29/2020] [Accepted: 11/23/2020] [Indexed: 11/29/2022]
Abstract
Study Objectives: Pneumonia, chronic obstructive pulmonary disease (COPD), and heart failure (HF) exacerbations can present similarly in the older adult in the Emergency Department (ED), leading to sub-optimal treatment from over- and under-diagnosis. There may be a role for antimicrobial peptides (AMPs) in improving the accurate diagnosis of pneumonia in these patients. Methods: This pilot was a prospective, observational cohort study of older adults (aged ≥65 years of age) who presented to the ED with dyspnea or elevated respiratory rate. To identify biomarkers of pneumonia, serum levels of white blood cell count, procalcitonin (PCT), and antimicrobial peptides (human beta defensin 1 and 2 [HBD-1, -2], human neutrophil peptides 1–3 [HNP1–3] and cathelididin [LL-37]) were compared between those with and without pneumonia. Criterion standard reviewers retrospectively determined the diagnoses present in the ED. Results: Three hundred ninety-one patients were screened, 140 were eligible, and 79 were enrolled. Based on criterion standard review, pneumonia was present in 10 (12.7%), COPD in 9 (11.4%) and HF in 31 (39.2%) with a co-diagnosis rate of 10.1% by criterion standard review. Comparatively, emergency medicine attending physicians diagnosed pneumonia in 16 (20.3%), COPD in 12 (15.2%), and HF in 30 (38.0%) with co-diagnosis rate of 15.2%. Emergency physicians agreed with criterion standard diagnoses in 90% of pneumonia, 75% of COPD and 65% of HF diagnoses. Differences in leukocyte count (p<0.01) and two novel AMPs (DEFA5 (p=0.08) and DEFB2 (p=0.09)) showed promise for diagnosing pneumonia. Conclusions: Emergency physicians continue to have poor diagnostic accuracy in dyspneic older adult patients. Serum AMP levels are one potential tool to improve diagnostic accuracy and outcomes for this important population and require further study.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is an essential consideration in patients presenting to primary care with respiratory symptoms; however, accurate diagnosis is difficult when clinical and radiological examinations are not possible, such as during telehealth consultations. AIM To develop and test a smartphone-based algorithm for diagnosing CAP without need for clinical examination or radiological inputs. DESIGN AND SETTING A prospective cohort study using data from participants aged >12 years presenting with acute respiratory symptoms to a hospital in Western Australia. METHOD Five cough audio-segments were recorded and four patient-reported symptoms (fever, acute cough, productive cough, and age) were analysed by the smartphone-based algorithm to generate an immediate diagnostic output for CAP. Independent cohorts were recruited to train and test the accuracy of the algorithm. Diagnostic agreement was calculated against the confirmed discharge diagnosis of CAP by specialist physicians. Specialist radiologists reported medical imaging. RESULTS The smartphone-based algorithm had high percentage agreement (PA) with the clinical diagnosis of CAP in the total cohort (n = 322, positive PA [PPA] = 86.2%, negative PA [NPA] = 86.5%, area under the receiver operating characteristic curve [AUC] = 0.95); in participants 22-<65 years (n = 192, PPA = 85.7%, NPA = 87.0%, AUC = 0.94), and in participants aged ≥65 years (n = 86, PPA = 85.7%, NPA = 87.5%, AUC = 0.94). Agreement was preserved across CAP severity: 85.1% (n = 80/94) of participants with CRB-65 scores 1 or 2, and 87.7% (n = 57/65) with a score of 0, were correctly diagnosed by the algorithm. CONCLUSION The algorithm provides rapid and accurate diagnosis of CAP. It offers improved accuracy over current protocols when clinical evaluation is difficult. It provides increased capabilities for primary and acute care, including telehealth services, required during the COVID-19 pandemic.

Diagnostic Errors Are Common in Acute Pediatric Respiratory Disease: A Prospective, Single-Blinded Multicenter Diagnostic Accuracy Study in Australian Emergency Departments. Front Pediatr 2021; 9:736018. [PMID: 34869099 PMCID: PMC8637207 DOI: 10.3389/fped.2021.736018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Accepted: 10/14/2021] [Indexed: 11/26/2022] Open
Abstract
Background: Diagnostic errors are a global health priority and a common cause of preventable harm. There is limited data available for the prevalence of misdiagnosis in pediatric acute-care settings. Respiratory illnesses, which are particularly challenging to diagnose, are the most frequent reason for presentation to pediatric emergency departments. Objective: To evaluate the diagnostic accuracy of emergency department clinicians in diagnosing acute childhood respiratory diseases, as compared with expert panel consensus (reference standard). Methods: Prospective, multicenter, single-blinded, diagnostic accuracy study in two well-resourced pediatric emergency departments in a large Australian city. Between September 2016 and August 2018, a convenience sample of children aged 29 days to 12 years who presented with respiratory symptoms was enrolled. The emergency department discharge diagnoses were reported by clinicians based upon standard clinical diagnostic definitions. These diagnoses were compared against consensus diagnoses given by an expert panel of pediatric specialists using standardized disease definitions after they reviewed all medical records. Results: For 620 participants, the sensitivity and specificity (%, [95% CI]) of the emergency department compared with the expert panel diagnoses were generally poor: isolated upper respiratory tract disease (64.9 [54.6, 74.4], 91.0 [88.2, 93.3]), croup (76.8 [66.2, 85.4], 97.9 [96.2, 98.9]), lower respiratory tract disease (86.6 [83.1, 89.6], 92.9 [87.6, 96.4]), bronchiolitis (66.9 [58.6, 74.5], 94.3 [80.8, 99.3]), asthma/reactive airway disease (91.0 [85.8, 94.8], 93.0 [90.1, 95.3]), clinical pneumonia (63·9 [50.6, 75·8], 95·0 [92·8, 96·7]), focal (consolidative) pneumonia (54·8 [38·7, 70·2], 86.2 [79.3, 91.5]). Only 59% of chest x-rays with consolidation were correctly identified. Between 6.9 and 14.5% of children were inappropriately prescribed based on their eventual diagnosis. Conclusion: In well-resourced emergency departments, we have identified a previously unrecognized high diagnostic error rate for acute childhood respiratory disorders, particularly in pneumonia and bronchiolitis. These errors lead to the potential of avoidable harm and the administration of inappropriate treatment.

Abstract
Purpose of review Pneumonia is a frequent disease mainly affecting older and multimorbid patients. Symptoms and signs lack sensitivity and specificity, and chest X-ray has poor accuracy. Hence, an initial diagnosis of pneumonia has limited predictive value for the presence of pneumonia. Overdiagnosis of pneumonia leads to inappropriate antibiotic use and may delay the appropriate management of mimicking diseases. Alternative imaging strategies including computed tomography (CT)-scan or lung ultrasonography may improve the diagnosis of pneumonia. We review the recent evidence and perspectives regarding their contribution to the diagnosis and management of patients with suspected pneumonia. Recent findings Two studies assessed the diagnostic accuracy of CT-scan in emergency department or hospitalized patients suspected of pneumonia. CT-scan led to a net reclassification improvement of 8 and 18% of patients, and was particularly helpful to rule out the diagnosis, allowing a lowering of the number of inappropriate antibiotic prescriptions. Summary CT-scan reduces overdiagnosis of pneumonia and allows a better identification of alternative diagnoses. The impact on clinical outcomes of a strategy incorporating CT-scan for patients suspected of pneumonia should be evaluated, along with its cost-effectiveness.

Abstract
BACKGROUND Achieving a high degree of diagnostic accuracy of infections in the emergency department (ED) is crucial since a delay in diagnosis can lead to increased mortality, whereas overdiagnosis can lead to antibiotic overprescription. Limited data are available as to ED diagnostic accuracy of infections. The aim of this study was to demonstrate the degree of discordance of an ED diagnosis of pneumonia in relation to an internal medicine ward's discharge diagnosis of hospitalized adults. METHODS We reviewed the records of all adults hospitalized in internal wards from November 2017-January 2018 diagnosed with an acute infection by an ED physician. The primary outcome was the discordance degree of an ED pneumonia diagnosis compared to the internal ward discharge diagnosis. The influence comorbidities and clinical characteristics on the diagnostic discordance were also evaluated. RESULTS The study included 875 adults; 434 were admitted with an ED diagnosis of a specific infection. Pneumonia was the most frequent ED diagnosis (n = 195, 45%), of them, 56 (29%) were discordant diagnosis in the internal ward. CONCLUSION Interpretation of chest X-rays with the assistance of a radiologist might help in reducing overdiagnosis and minimize antibiotic overprescription, thus improving the ED diagnostic accuracy of pneumonia.

Abstract
OBJECTIVES To determine if nonspecific symptoms and fever affect the posttest probability of acute bacterial infection in older patients in the emergency department (ED). DESIGN Preplanned, secondary analysis of a prospective observational study. SETTING Tertiary care, academic ED. PARTICIPANTS A total of 424 patients in the ED, 65 years or older, including all chief complaints. MEASUREMENTS We identified presence of altered mental status, malaise/lethargy, and fever, as reported by the patient, as documented in the chart, or both. Bacterial infection was adjudicated by agreement among two or more of three expert reviewers. Odds ratios were calculated using univariable logistic regression. Positive and negative likelihood ratios (PLR and NLR, respectively) were used to determine each symptom's effect on posttest probability of infection. RESULTS Of 424 subjects, 77 (18%) had bacterial infection. Accounting for different reporting methods, presence of altered mental status (PLR range, 1.40-2.53) or malaise/lethargy (PLR range, 1.25-1.34) only slightly increased posttest probability of infection. Their absence did not assist with ruling out infection (NLR, greater than 0.50 for both). Fever of 38°C or higher either before or during the ED visit had moderate to large increases in probability of infection (PLR, 5.15-18.10), with initial fever in the ED perfectly predictive, but absence of fever did not rule out infection (NLR, 0.79-0.92). Results were similar when analyzing lower respiratory, gastrointestinal, and urinary tract infections (UTIs) individually. Of older adults diagnosed as having UTIs, 47% did not complain of UTI symptoms. CONCLUSIONS The presence of either altered mental status or malaise/lethargy does not substantially increase the probability of bacterial infection in older adults in the ED and should not be used alone to indicate infection in this population. Fever of 38°C or higher is associated with increased probability of infection. J Am Geriatr Soc 67:484-492, 2019.

Abstract
OBJECTIVES To compare the accuracy of the Loeb criteria, emergency department (ED) physicians' diagnoses, and Centers for Disease Control and Prevention (CDC) guidelines for acute bacterial infection in older adults with a criterion standard expert review. DESIGN Prospective, observational study. SETTING Urban, tertiary-care ED. PARTICIPANTS Individuals aged 65 and older in the ED, excluding those who were incarcerated, underwent a trauma, did not speak English, or were unable to consent. MEASUREMENTS Two physician experts identified bacterial infections using clinical judgement, participant surveys, and medical records; a third adjudicated in cases of disagreement. Agreement and test characteristics were measured for ED physician diagnosis, Loeb criteria, and CDC surveillance guidelines. RESULTS Criterion-standard review identified bacterial infection in 77 of 424 participants (18%) (18 (4.2%) lower respiratory, 19 (4.5%) urinary tract (UTI), 22 (5.2%) gastrointestinal, 15 (3.5%) skin and soft tissue). ED physicians diagnosed infection in 71 (17%), but there were 33 with under- and 27 with overdiagnosis. Physician agreement with the criterion standard was moderate for infection overall and each infection type (κ = 0.48-0.59), but sensitivity was low (<67%), and the negative likelihood ratio (LR(-)) was greater than 0.30 for all infections. The Loeb criteria had poor sensitivity, agreement, and LR(-) for lower respiratory (50%, κ = 0.55; 0.51) and urinary tract infection (26%, κ = 0.34; 0.74), but 87% sensitivity (κ = 0.78; LR(-) 0.14) for skin and soft tissue infections. CDC guidelines had moderate agreement but poor sensitivity and LR(-). CONCLUSION Emergency physicians often under- and overdiagnose infections in older adults. The Loeb criteria are useful only for diagnosing skin and soft tissue infections. CDC guidelines are inadequate in the ED. New criteria are needed to aid ED physicians in accurately diagnosing infection in older adults.

Abstract
RATIONALE Lower respiratory tract illness (LRTI) frequently causes adult hospitalization and antibiotic overuse. Procalcitonin (PCT) treatment algorithms have been used successfully in Europe to safely reduce antibiotic use for LRTI but have not been adopted in the United States. We recently performed a feasibility study for a randomized clinical trial (RCT) of PCT and viral testing to guide therapy for non-pneumonic LRTI. OBJECTIVE The primary objective of the current study was to understand factors influencing PCT algorithm adherence during the RCT and evaluate factors influencing provider antibiotic prescribing practices for LRTI. STUDY DESIGN From October 2013-April 2014, 300 patients hospitalized at a community teaching hospital with non-pneumonic LRTI were randomized to standard or PCT-guided care with viral PCR testing. Algorithm adherence data was collected and multivariate stepwise logistic regression of clinical variables used to model algorithm compliance. 134 providers were surveyed anonymously before and after the trial to assess knowledge of biomarkers and viral testing and antibiotic prescribing practices. RESULTS Diagnosis of pneumonia on admission was the only variable significantly associated with non-adherence [7% (adherence) vs. 26% (nonadherence), p = 0.01]. Surveys confirmed possible infiltrate on chest radiograph as important for provider decisions, as were severity of illness, positive sputum culture, abnormal CBC and fever. However, age, patient expectations and medical-legal concerns were also at least somewhat important to prescribing practices. Physician agreement with the importance of viral and PCT testing increased from 42% to 64% (p = 0.007) and 49% to 74% (p = 0.001), respectively, after the study. CONCLUSIONS Optimal algorithm adherence will be important for definitive PCT intervention trials in the US to determine if PCT guided algorithms result in better outcomes than reliance on traditional clinical variables. Factors influencing treatment decisions such as patient age, presence of fever, patient expectations and medical legal concerns may be amenable to education to improve PCT algorithm compliance for LRTI.

Abstract
Respiratory infections account for 63.8% of infections met. Of which a quarter are lower respiratory tract: acute bronchitis, exacerbation of COPD or bronchiectasis and pneumonia. Acute bronchitis usually of viral etiology and in immunocompetent patients without comorbidity treatment is symptomatic with analgesics and anti-inflammatories. The main cause of exacerbation of COPD is the respiratory infection. The indication of empirical antibiotic choice and it is based on clinical criteria, the severity of the underlying disease, the severity of the exacerbation and the presence of risk factors for infection with Pseudomonas aeruginosa. The community-acquired pneumonia (CAP) is the leading cause of death by infection. The use of prognostic severity scales (PSI or CURB-65) is recommended for deciding where treatment is started, the tests to be performed for the etiological diagnosis and the recommended empirical antibiotic therapy. Patients with Healthcare Associated Pneumonia (HCAP) and nosocomial pneumonia (NP) have a higher risk of infection by multiresistant microorganisms (MMR) and increased morbidity and mortality. It requires specific empirical treatment depending on the severity of disease and risk factors for infection MMR.

Abstract
BACKGROUND AND OBJECTIVE Imperfect diagnostic tools make it difficult to know the extent to which a bacterial process is contributing to respiratory illness, complicating the decision to prescribe antibiotics. We sought to quantify diagnostic and antibiotic prescribing disagreements between emergency department (ED) and pediatric hospitalist physicians for children admitted with respiratory illness. METHODS Manual chart review was used to identify testing, diagnostic, and antibiotic prescribing decisions for consecutive children admitted for respiratory illness in a winter (starting February 20, 2012) and a summer (starting August 20, 2012) season to a tertiary, freestanding children's hospital. Respiratory illness diagnoses were grouped into 3 categories: bacterial, viral, and asthma. RESULTS A total of 181 children admitted for respiratory illness were studied. Diagnostic discordance was significant for all 3 types of respiratory illness but greatest for bacterial (P<.001). Antibiotic prescribing discordance was significant (P<.001), with pediatric hospitalists changing therapy for 93% of patients prescribed antibiotics in the ED, including stopping antibiotics altogether for 62% of patients. CONCLUSIONS Significant diagnostic and antibiotic discordance between ED and pediatric hospitalist physicians exists for children admitted to the hospital for respiratory illness.

Abstract
BACKGROUND Community-acquired pneumonia (CAP) is an important cause of acute respiratory disease in ambulatory care settings. The objective of this study was to assess the accuracy of medical history and physical examination in diagnosing CAP. METHODS Pediatric residents prospectively completed a questionnaire documenting patients' medical history and physical examination whenever a chest radiograph was ordered on patients 1 month to 16 years of age. Chest radiographs were read by a pediatric radiologist. RESULTS Of 525 children participating in the study, 181 (34%) demonstrated findings of pneumonia. Thirty-four (19%) had no symptoms other than fever, and 51 (28%) had normal lung auscultation. Pediatric residents had the same interpretation in 85% of cases in which radiographic CAP was diagnosed by the radiologist, and in 76% of cases in which radiographic pneumonia was excluded by the radiologist. CONCLUSIONS Results demonstrate the significant added value of chest radiography as an ancillary test for diagnosis of pneumonia in the emergency department setting.

Abstract
BACKGROUND Time to first antibiotic (TTFA) is postulated to impact pneumonia mortality. The Joint Commission/Centers for Medicare and Medicaid Services national quality standards previously indicated that TTFA should be <6 h (modified from <4 h when the study was initiated, now eliminated as a time measure entirely). OBJECTIVE The purpose of this article was to determine whether TTFA is associated with inpatient mortality. METHODS The records of 444 consecutive patients admitted with pneumonia at a single institution were retrospectively reviewed for a correlation between TTFA and inpatient complications, including death. Statistical significance was set at p < 0.01 due to multiple comparisons. RESULTS Patients whose TTFA was <4 h had more complications (27% vs. 3%; p < 0.01) including death, intensive care unit admission, and intubation. These patients were judged sicker on arrival (median Emergency Severity Index 2 vs. 3; p < 0.001) and were more likely to be triaged to a critical care bed (36% vs. 5%; p < 0.001). Shortness of breath was the only presenting factor that was more frequent in the TTFA <4-h group (61% vs. 16%; p < 0.01). CONCLUSIONS Shorter TTFA is not associated with improved inpatient mortality. TTFA should not be considered to be a marker of quality of care but rather a reflection of patient disease severity.

Abstract
BACKGROUND The difficulty to diagnose community-acquired pneumonia (CAP) and the lack of scientific data regarding the optimal duration of antibiotic therapy are responsible for overprescribing antibiotics. OBJECTIVE The authors had for objective to perform a systematic review of the international medical literature on strategies aimed at reducing antibiotic consumption for CAP. METHODS We performed a Pubmed search using the keywords CAP, antibiotic use, duration of antibiotic therapy, procalcitonin, short-course treatment, and biomarkers. We then made a critical review of the selected articles. RESULTS Our review identified two strategies used to reduce antibiotic consumption for CAP. The first one was based on procalcitonin (PCT) use. This strategy, even though reducing the duration of antibiotic therapy, does not seem optimal since it is associated with longer antibiotic treatment than recommended by the Infectious Diseases Society of America. Moreover, this strategy is associated with an increased cost in biochemical tests. The other strategy is based on a 2-step clinical reassessment: 1) during the first 24 hours of hospitalization, to confirm the diagnosis of CAP and 2) during hospitalization, to shorten the duration of antibiotic therapy according to the patient's clinical status. CONCLUSION Clinical reassessment, currently little studied compared to PCT guidance algorithm, seems to be promising to reduce antibiotic consumption for CAP. Especially since it was never compared to PCT guidance strategy in a randomized clinical trial.

Abstract
BACKGROUND Clinical diagnosis of pneumonia is difficult and chest radiographs often indeterminate, leading to incorrect diagnoses and antibiotic overuse. OBJECTIVE To determine if serum procalcitonin (ProCT) could assist in managing patients with respiratory illness and indeterminate radiographs. DESIGN Subjects were prospectively enrolled during 2 consecutive winters. SETTING A 520-bed hospital in Rochester, NY. PATIENTS Five hundred twenty-eight adults admitted with acute respiratory illness were enrolled. MEASUREMENTS Serum ProCT, admission diagnoses, and chest radiographic findings were used to derive receiver operating characteristics curves to assess predictive accuracy of ProCT for the presence of infiltrates. RESULTS Subjects with pneumonia had higher ProCT (median 0.27 ng/ml) than those with exacerbations of chronic obstructive pulmonary disease (0.08 ng/ml), acute bronchitis (0.09 ng/ml), or asthma (0.06 ng/ml). ProCT had moderate accuracy for the presence of infiltrates (area under curve [AUC] 0.72), when indeterminate radiographs were independently classified as infiltrates by a pulmonologist evaluating patients. CONCLUSIONS ProCT may be useful in diagnosing pneumonia when chest radiographs are indeterminate.

Abstract
OBJECTIVES Older adults with infection are at increased risk of misdiagnosis while they are patients in the emergency department (ED) due to the common presence of nonspecific signs and symptoms. The primary objective was to determine the proportion of admitted older adult patients thought by the emergency physician (EP) to be infected, as compared with the diagnostic impression of inpatient physicians. The secondary objective was to determine the agreement between EP and inpatient physician diagnosis of specific infection types. METHODS The authors conducted a prospective, observational, convenience sampling of a cohort of ED patients ≥65 years old admitted to the hospital with diagnoses of acute infection. EPs noted at least one suspected source of infection. Inpatient diagnosis of infection was determined by chart review of the inpatient chart. Outcomes included the presence of any infection and of specific infectious sources diagnosed within 48 hours of admission. EP and inpatient diagnoses were compared using proportions, positive and negative likelihood ratios (LR+ and LR-), and the phi coefficient. RESULTS The study included 103 patients diagnosed with a suspected infection by the EP. Nineteen patients (18.4%, 95% confidence interval [CI] = 11.5% to 27.3%) were not diagnosed with any infection by the inpatient physician. For specific infection sources, ED diagnosis of bloodstream infection often did not agree with the inpatient diagnosis. Sensitivity was 40.0% and specificity 78.4% with an LR+ of 1.85 and LR- of 0.76. The phi coefficient was 0.15. EPs overdiagnosed pulmonary infection, with 72.1% specificity and an LR+ of 3.24. EP diagnosis had good accuracy for skin and soft tissue infection (sensitivity = 78.6% and specificity = 96.6%), with adequate LRs (LR+ of 23.3 and LR- of 0.22). Urinary tract infection (UTI) was underdiagnosed in the ED (sensitivity = 58.3%), but it is unclear if this is due to true ED underdiagnosis or due to overdiagnosis of UTI in the inpatient setting. CONCLUSIONS In older patients admitted from the ED, the provisional ED diagnosis and the inpatient diagnosis of an acute infection often disagree. In this sample, 18% of older ED patients diagnosed with infection during an ED stay were not diagnosed as infected by the inpatient physician. Regarding infection types, EPs were poor at diagnosing bacteremia and overdiagnosed pulmonary infections. EP diagnosis of skin and soft tissue infection generally agreed with the inpatient physician. There was also disagreement regarding presence of UTI, but the true nature of this difference is unclear from the data obtained in this study.
