A 77-year old male was admitted in the emergency department for septic shock, yet no clear source of infection was noted upon physical examination and a portable chest x-ray. Due to his unstable condition, bedside ultrasound was performed. A heterogeneous mass in the liver was noted, hence a tentative diagnosis of liver abscess was made. This was latter confirmed by abdominal computed tomography. This case highlights that point-of-care ultrasound, when performed by expert physicians, can significantly decrease time to diagnosis for septic patients.

A 56-year-old male was admitted to the emergency department for acute pulmonary edema and septic shock, yet no clear source of infection was noted upon physical examination. Due to his unstable condition, bedside ultrasound was performed. A heterogeneous mass in the liver was noted; hence, a tentative diagnosis of liver abscess was made. The abscess was confirmed by abdominal magnetic resonance imaging. Drainage of the abscess was attempted and guided by early ultrasound. This case highlights that point-of-care ultrasound, when performed by an ultrasound-capable critical care physician, can significantly decrease the time to diagnosis for septic patients.

The Impact

Abstract Background Symptomatic pericardial effusion (PCE) presents with non-specific features and are often missed on the initial physical exam, chest X-ray (CXR), and electrocardiogram (ECG). In extreme cases, misdiagnosis can evolve into decompensated cardiac tamponade, a life-threatening obstructive shock. The purpose of this study is to evaluate the impact of point-of-care ultrasound (POCUS) on the diagnosis and therapeutic intervention of clinically significant PCE. Methods In a retrospective chart review, we looked at all patients between 2002 and 2018 at a major Canadian academic hospital who had a pericardiocentesis for clinically significant PCE. We extracted the rate of presenting complaints, physical exam findings, X-ray findings, ECG findings, time-to-diagnosis, and time-to-pericardiocentesis and how these were impacted by POCUS. Results The most common presenting symptom was dyspnea (64%) and the average systolic blood pressure (SBP) was 120 mmHg. 86% of people presenting had an effusion > 1 cm, and 89% were circumferential on departmental echocardiogram (ECHO) with 64% having evidence of right atrial systolic collapse and 58% with early diastolic right ventricular collapse. The average time-to-diagnosis with POCUS was 5.9 h compared to > 12 h with other imaging including departmental ECHO. Those who had the PCE identified by POCUS had an average time-to-pericardiocentesis of 28.1 h compared to > 48 h with other diagnostic modalities. Conclusion POCUS expedites the diagnosis of symptomatic PCE given its non-specific clinical findings which, in turn, may accelerate the time-to-intervention.

AbstractThere is evidence to suggest that point-of-care ultrasound assessment of the lungs has a higher sensitivity and specificity than chest radiography for the diagnosis of pneumonia. It is unknown if the same is true for pneumonia complications. We present and discuss the case of a 61-year-old woman who presented to the emergency department with confusion, decreased level of consciousness, and signs of sepsis. A chest x-ray revealed a right sided infiltrate. An ultrasound of the patient’s lungs was performed, and revealed a complex loculated fluid collection consistent with an empyema. A chest CT confirmed the diagnosis, and immediate percutaneous drainage was performed.

Delays In Diagnosis

AbstractDespite decades of research, the mortality rate of sepsis and septic shock remains unacceptably high. Delays in diagnosis, identification of an infectious source, and the challenge of providing patient-tailored resuscitation measures routinely result in suboptimal patient outcomes. Bedside ultrasound improves a clinician's ability to both diagnose and manage the patient with sepsis. Indeed, multiple point-of-care ultrasound (POCUS) protocols have been developed to evaluate and treat various subsets of critically ill patients. These protocols mostly target patients with undifferentiated shock and have been shown to improve clinical outcomes. Other studies have shown that POCUS can improve a clinician's ability to identify a source of infection. Once a diagnosis of septic shock has been made, serial POCUS exams can be used to continuously guide resuscitative efforts. In this review, we advocate that the patient with suspected sepsis or septic shock undergo a comprehensive POCUS exam in which sonographic information across organ systems is synthesized and used in conjunction with traditional data gleaned from the patient's history, physical exam, and laboratory studies. This harmonization of information will hasten an accurate diagnosis and assist with hemodynamic management.

Background: As point-of-care ultrasound (POCUS) becomes a standard of care procedure, medical schools around the world have started to seek the integration of POCUS courses into their curricula. This puts medical students in a unique position as they are trained in an area in which many physicians lack knowledge. This case series provides a glimpse into the capabilities of POCUS even when used by medical students. Methods: Fourth-year medical students at Ben-Gurion University of the Negev performed numerous POCUS exams during their first clinical rotation at Soroka University Medical Center in Israel. All students completed a course in basic POCUS training and were evaluated in a brief practical exam before entering their first clinical rotation. Four of the cases in which the students took part are presented in this case series. Results: The POCUS exam in the first case discovered pulmonary embolism in addition to the diagnosis of Cushing disease. In the second case, endocarditis could have been diagnosed three days earlier had a POCUS exam been performed. Case 3 demonstrates the additional contribution of POCUS to the decision-making process carried out by physicians and its superiority in quantifying and diagnosing pleural effusion compared to chest X-Ray. Case 4 indicated that POCUS is preferable over chest X-ray and auscultation for the diagnosis of pulmonary edema. Conclusion: This case series may emphasize the capabilities POCUS has when utilized in the standard physical examination and the importance of incorporating POCUS instruction in medical schools for new physicians to acquire this skill.

Abstract Background Childhood pneumonia is one of the leading causes of death in low-income countries. The diagnosis of pediatric pneumonia is a critical epidemiological duty for treatment effectiveness and vaccine surveillance. Previous studies have demonstrated an important lack in correlation between CXR findings and the clinical WHO case definition of severe pneumonia. Lung Point of Care Ultrasound (POCUS) has demonstrated in multiple studies to be more sensitive and specific for diagnosing pneumonia in the pediatric population. With no exposure to radiation, extensive availability in limited-resource settings, and easy interpretation, this modality can be a breakpoint in making a more accurate correlation between pneumonia clinical findings and diagnostic imaging. Methods 50 children from 1-59 months meeting the WHO case definition of severe pneumonia were enrolled at the Emergency Department at University Teaching Hospital (UTH) in Lusaka, Zambia. Children underwent lung POCUS and CXR. Correlation between symptoms and all abnormalities (consolidation, effusion, and interstitial patterns) seen in both imaging modalities were analyzed by calculating the proportion of children with abnormalities on CXR and ultrasound. Each participant was assigned a score based on findings. 0 = normal, 1 = consolidation only, 2 = Consolidation and non-consolidation (interstitial and/or effusion) and 3 = non-consolidation (interstitial and/or effusion) only. Results 44 (90%) of children had abnormalities on CXR and 46 (94%) on POCUS. Five children (10%) had normal findings on CXR vs 3 (6%) on Lung POCUS. 4 (8%) had consolidation only on CXR vs 0 (0%) on POCUS. 19 (39%) had consolidation and non-consolidation (interstitial and/or effusion) on CXR vs. 20 (41%) on POCUS. 21 (43%) had non-consolidation (interstitial and/or effusion) only on CXR vs. 26 (53%) on POCUS. Figure 1. Scores Asigned Based on Imaging Findings for CXR and Lung POCUS Figure 2. Chest X Ray Anterior Posterior (AP) view showing Bilareral Interstitial Pattern Figure 3. Lung POCUS (Point of Care Ultrasound) findings of bilateral Consolidation and non-consolidation pattern and bilateral interstitial pattern (only finding on CXR) Conclusion More children with clinical pneumonia had normal findings on CXR than on POCUS. POCUS was a better imaging technique to show consolidation and non-consolidation patterns than CXR. The higher proportion of children diagnosed with consolidation and non-consolidation patterns on POCUS suggest that CXR might not be the ideal gold standard to diagnose pneumonia in children.

Abstract lung ultrasound (LUS) was used traditionally in the assessment of pleural effusions and masses but LUS has moved towards the imaging of the pulmonary parenchyma, mainly as a point-of-care technique. Objective To assess the agreement between LUS and CXR for the diagnosis of RD in neonates. Methods This prospective cross sectional study was conducted on 100 neonates presents with RD in the first 24 hours of life in the neonatal intensive care unit (NICU) of the Ain Shams University. All enrolled neonates underwent LUS and CXR initially and on day 7. Neonatologists were blind to the LUS diagnosis and the clinical decisions were driven by CXR findings. Lung score was applied to describe lung aeration, interstitial, alveolar, or consolidation patterns for each lung area. Results 125 different diagnoses were reported in 100 patients. The total agreement between LUS and CXR diagnosis was 96% (95% CI 88–98%) with a κ statistic of 0.94 (95% CI 0.86– 1.00). The agreement for RDS, Pneumonia, TTN, MAS, CDH, PE, Pnumothorax and atelectasis were 99%, 96%,98%, 99%,100%,100%,98% and 98% consequently. Conclusion LUS is a safe, low coast, easy to operate and has high agreement with CXR for the diagnosis of RD in neonates in the first week of life.

IntroductionAvoiding low value medical practices is an important focus in current healthcare utilisation. Despite advantages of point-of-care ultrasound (POCUS) over chest X-ray including improved workflow and timeliness of results, POCUS-guided central venous catheter (CVC) position confirmation has slow rate of adoption. This demonstrates a gap that is ripe for the development of an intervention.MethodsThe intervention is a deimplementation programme called DRAUP (deimplementation of routine chest radiographs after adoption of ultrasound-guided insertion and confirmation of central venous catheter protocol) that will be created to address one unnecessary imaging modality in the acute care environment. We propose a three-phase approach to changing low-value practices. In phase 1, we will be guided by the Consolidated Framework for Implementation Research framework to explore barriers and facilitators of POCUS for CVC confirmation in a single centre, large tertiary, academic hospital via focus groups. The qualitative methods will inform the development and adaptation of strategies that address identified determinants of change. In phase 2, the multifaceted strategies will be conceptualised using Morgan’s framework for understanding and reducing medical overuse. In phase 3, we will locally implement these strategies and assess them using Proctor’s outcomes (adoption, deadoption, fidelity and penetration) in an observational study to demonstrate proof of concept, gaining valuable insights on the programme. Secondary outcomes will include POCUS-guided CVC confirmation efficacy measured by time and effectiveness measured by sensitivity and specificity of POCUS confirmation after CVC insertion.With limited data available to inform interventions that use concurrent implementation and deimplementation strategies to substitute chest X-ray for POCUS using the DRAUP programme, we propose that this primary implementation and secondary effectiveness pilot study will provide novel data that will expand the knowledge of implementation approaches to replacing low value or unnecessary care in acute care environments.Ethics and disseminationApproval of the study by the Human Research Protection Office has been obtained. This work will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at scientific meetings and data sharing with other investigators through academically established means.Trial registration numberClinicalTrials.gov Identifier, NCT04324762, registered on 27 March 2020.
