Systematic Sonography for Detection of Occult Wounds in Trauma.

Treating victims of penetrating trauma is challenging, especially in a mass-casualty or resource-limited setting. The traditional focused assessment with sonography for trauma examination is a well-established clinical tool in the initial evaluation of trauma victims. This article describes a novel technique of systematic sonography of the abdomen to look for occult wounds, which is used in conjunction with the focused assessment with sonography for trauma examination to evaluate occult intraperitoneal injury and improve patient treatment and use of resources. The technique is highlighted in a case of a child injured in a conflict zone in northern Iraq.

Implementing a Fascia Iliaca Compartment Block Curriculum in an Emergency Medicine Residency Program.

With pain being commonly stated as a reason for presentation to the emergency department (ED) and the advent of the opioid crisis in the United States, regional anesthesia has been gaining prominence as an alternative treatment for acute pain in emergency medicine. However, to this date, there is no widely agreed-upon and standardized training regimen for regional anesthesia in emergency medicine residency programs. In this paper, we set out to define elements of competency for a residency program in a large academic tertiary center and to create a protocol for resident training that could be easily replicated, with a secondary goal of increasing the frequency of nerve blocks in the ED. We also aimed to discuss a curriculum that has been shown to improve resident comfortability with the fascia iliaca compartment block (FICB). This led to a substantial increase in nerve blocks performed in the ED. However, we also demonstrate a loss of retention at six months, indicating that further curriculum refinements will be needed to promote longitudinal retention of knowledge.

Effect of Departmental and Physician-Selected Interventions on Point-of-Care Ultrasound Documentation Completion.

Background Point-of-care ultrasound (POCUS) has been disruptive to many experienced emergency physicians as it requires competence in a new physical skill, real-time image interpretation, and navigation of novel software for submission to the electronic health record (EHR). Incomplete documentation of a performed POCUS study used for clinical decision-making represents a potential medicolegal liability, may expose the patient to repetitive or potentially unnecessary imaging, and is a missed opportunity for reimbursement. Identifying effective facilitators of ED POCUS documentation completion requires additional investigation. Methods In the first part of this mixed-methods study, eligible attending physicians were stratified into levels of use ("high"/"low"/"never") based on recent POCUS documentation performance. Semi-structured interviews were conducted with high and low utilizers to explore their perceptions of the POCUS submission workflow and their receptivity to various proposed interventions. Qualitative data were analyzed using a thematic analysis that explored perceived usefulness and usability. The second part of the study consisted of two intervention phases. First, physicians achieving minimum POCUS documentation numbers were rewarded with additional shift scheduling flexibility. In the second phase, the intervention that garnered the most interview support, daily documentation reminder emails, was implemented. The primary outcome was the individual POCUS documentation rates calculated as all studies submitted divided by all studies performed (submitted plus unsubmitted) per month. Provider-level monthly data was aggregated into a departmental rate. Results Interviews were conducted with 12 physicians, six from the highest and six from the lowest documentation quartiles. Both groups supported the same two proposed interventions: reminder emails ranked first, then monetary rewards ranked second. High utilizers emphasized the clinical utility of POCUS, whereas low utilizers expressed concerns over "double billing" and exposure to medicolegal liability with uncertain scan interpretations. For low utilizers, a documentation decision could be dependent on the performing resident physician's displayed confidence. Both groups voiced frustration with the need to use a separate program, Qpath (Telexy Healthcare, Inc, Maple Ridge, British Columbia, Canada), for POCUS documentation. During intervention phase one, the aggregate departmental documentation rate increased from 44.6% to 60.1% with the introduction of the schedule request incentive. This improvement was seen across all documentation quartiles. The departmental rate remained stable and did not improve further following the addition of the daily documentation reminder emails in intervention phase two. When reminder emails ceased yet the day-off request incentive continued, the departmental rate did not drop. Conclusions The implementation of a non-financial shift scheduling incentive correlated with the largest increase in departmental POCUS documentation rate. Interviewees incorrectly predicted that email reminders would be the most influential intervention highlighting a mismatch between physician perception and effective drivers of behavior change. Further investigation may focus on determining the size and longevity of the isolated impact of a schedule request incentive, as one might expect diminishing marginal utility.

Evaluation of an emergency medicine point-of-care ultrasound curriculum adapted for a resource-limited setting in Guyana.

BACKGROUND: This is a cohort pilot study of senior emergency medicine residents and residency-trained emergency medicine registrars practicing in an urban tertiary academic hospital in Guyana in South America. The primary aim was to assess the effectiveness of the current adapted residency ultrasound training curriculum and guide future ultrasound-specific continuing medical education. Ultrasound image acquisition, interpretation, and integration of ultrasound findings into clinical medical decision-making competency were assessed in a multimodal fashion: a written assessment and a practical assessment. METHODS: This was a cross-sectional cohort pilot study of senior emergency medicine residents and registrars (residency graduates) practicing in Guyana, a low-middle-income country. Ultrasound image acquisition and interpretation competency were assessed in a multimodal fashion: a written assessment and a practical assessment. The results will be reported as simple percentages. Participants will be deemed competent if the combined score is greater than 80% on the assessment. RESULTS: All senior residents and graduates of the residency program were competent in the core point-of-care ultrasound applications. The senior residents averaged 89% proficiency, and the residency graduates subdivided based on years since graduation averaged 87-100% proficiency. The more experienced providers performed better on the practical portion of the evaluation. Evaluating the composite analysis of all the participants revealed the Extended Focused Assessment with Sonography in Trauma (EFAST) exam (96%) and cardiac exam (93%) were done with the most proficiency. CONCLUSION: The assessment results of this pilot study suggest that the current residency ultrasound training curriculum adapted to the resources available is associated with sustained competency after graduation. There was minor attrition of knowledge amongst the senior physicians, but all senior residents and all participating residency graduates were competent in the core ultrasound applications.

Early Serial Echocardiographic and Ultrasonographic Findings in Critically Ill Patients With COVID-19.

Background: Cardiac function of critically ill patients with COVID-19 generally has been reported from clinically obtained data. Echocardiographic deformation imaging can identify ventricular dysfunction missed by traditional echocardiographic assessment. Research Question: What is the prevalence of ventricular dysfunction and what are its implications for the natural history of critical COVID-19? Study Design and Methods: This is a multicenter prospective cohort of critically ill patients with COVID-19. We performed serial echocardiography and lower extremity vascular ultrasound on hospitalization days 1, 3, and 8. We defined left ventricular (LV) dysfunction as the absolute value of longitudinal strain of < 17% or left ventricle ejection fraction (LVEF) of < 50%. Primary clinical outcome was inpatient survival. Results: We enrolled 110 patients. Thirty-nine (35.5%) died before hospital discharge. LV dysfunction was present at admission in 38 patients (34.5%) and in 21 patients (36.2%) on day 8 (P = .59). Median baseline LVEF was 62% (interquartile range [IQR], 52%-69%), whereas median absolute value of baseline LV strain was 16% (IQR, 14%-19%). Survivors and nonsurvivors did not differ statistically significantly with respect to day 1 LV strain (17.9% vs 14.4%; P = .12) or day 1 LVEF (60.5% vs 65%; P = .06). Nonsurvivors showed worse day 1 right ventricle (RV) strain than survivors (16.3% vs 21.2%; P = .04). Interpretation: Among patients with critical COVID-19, LV and RV dysfunction is common, frequently identified only through deformation imaging, and early (day 1) RV dysfunction may be associated with clinical outcome.

Description of the Use of Incentives and Penalties for Point-of-Care Ultrasound Documentation Compliance in an Academic Emergency Department.

Objectives Incomplete documentation and submission to the electronic health record of performed point-of-care ultrasound (POCUS) studies is problematic from a patient care, medicolegal, and billing standpoint. Positive and negative financial incentives may be used to motivate physicians to complete documentation workflow. The most efficacious route to improve POCUS workflow completion remains to be determined. Materials and methods A retrospective analysis of POCUS documentation in an academic emergency department during four distinct six-month blocks was performed. POCUS workflow completion was assessed without incentives (Baseline), with financial bonus (Incentive), interim period (Washout), and with a negative financial incentive (Penalty) to determine the effect of these incentives on workflow completion. Results There was an appreciable increase in the rate of POCUS studies documented between the "Baseline" (no incentive) and "Incentive" (small financial bonus) time periods. The improvement remained stable during the "Washout" (interim) period, and then increased further in the "Penalty" (negative financial incentive) period. This improvement was relatively diffuse among the providers studied. A similar pattern - improvements in the Incentive and Penalty periods with stability in the Washout - was also observed in the POCUS volume data (number of studies performed). Conclusions This study reveals a positive association between the implementation of both financial incentives and financial penalties, which increases in POCUS documentation among attending physicians at an academic emergency department.

Systematic Sonography Looking for Occult Wounds: accuracy of an abdominal ultrasound adjunct in penetrating trauma.

BACKGROUND: Systematic Sonography Looking for Occult Wounds (SSLOW) in trauma is a novel technique for the evaluation of intra-abdominal wounds in penetrating trauma. No data exist regarding the effectiveness. The objective of this study was to evaluate the accuracy of the SSLOW exam. METHODS: This is a prospective collected case series conducted over a period of 10 months and took place at the Accident and Emergency Department (A&E) of the Georgetown Public Hospital Corporation (GPHC). The study enrolled patients presenting to the A&E who were 16 years old or greater with penetrating abdominal trauma. All patients with penetrating trauma received an E-FAST examination. If the E-FAST examination was negative, a SSLOW examination was completed. The sonographer evaluated for free fluid collection between the loops of bowel. The results of the SSLOW were compared to usual care (surgery consult, serial abdominal and E-FAST exams, laparotomy, and 7-day follow-up) and then categorized into four groups: true positive, false positive, true negative, and false negative. These results lead to four categorical values. From these results, sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratios were calculated. RESULTS: There were 5 (12%) true positives, 1 (2%) false positive, 37 (86%) true negatives, and zero (0%) false negative. The SSLOW was 100% sensitive (95% CI 5-100%) and 97% specificity (95% CI 74-96%). There was an 80% positive predictive value (95% CI 1.0-64% 95% CI) and 100% negative predictive value (95% CI 88-100%). The positive likelihood ratio was 8.4 (95% CI 3.69-19.1) and negative likelihood ratio was 0. CONCLUSION: The SSLOW examination may be a useful tool in the evaluation of penetrating abdominal injuries.

Observational descriptive study of ultrasound use and its impact on clinical decisions in the accident and emergency department at Georgetown public hospital corporation.

INTRODUCTION: Point-of-care ultrasound (POCUS) is physician-performed at the bedside, and it is a powerful diagnostic tool, especially in resource-limited emergency medicine healthcare settings. This study aims to quantify both the use of ultrasound and its impact on patient care at the Accident and Emergency Department at the Georgetown Public Hospital Corporation (GPHC). METHODS: This is a cross-sectional observational descriptive analysis of data collected for quality assessment in the GPHC Accident and Emergency Department. Over the course of two months, physicians were asked to record each ultrasound exam performed and record whether the ultrasound results changed patient disposition or the medication used in management. RESULTS: During the study period, there were 173 ultrasound data sheets collected representing 426 ultrasound studies. 196 studies were positive with pathologic findings (46.0%). The use of ultrasound in patient care either changed the patient's final disposition or medication 78.6% of the time. CONCLUSION: Ultrasound is used frequently at the Georgetown Public Hospital Corporation for a wide variety of applications. When utilized, POCUS frequently influenced patient care.

Emergency Ultrasound Training Program in Guyana: Systematic Credentialing Process in a Resource-limited Setting.

Ultrasound has become an important skill for emergency physicians. Ultrasound is more crucial in resource-limited settings where diagnostic testing may not be as timely or available at all. In 2015, an emergency medicine ultrasound curriculum was implemented at Georgetown Public Hospital Corporation in Georgetown, Guyana. Implementing an ultrasound-training curriculum in Guyana had four main challenges: limited ultrasound equipment, lack of informational technology infrastructure to record and review ultrasound examinations, availability of local emergency ultrasound expertise, and competing educational needs within the curriculum. These challenges were met with creative solutions and the formation of a formalized curriculum and credentialing process. The experience of creating the program is described along with the curriculum, credentialing process, and plan for sustainability. Since implementation, every graduating resident has displayed competency on final assessment.

Design and rationale of the B-lines lung ultrasound guided emergency department management of acute heart failure (BLUSHED-AHF) pilot trial.

BACKGROUND: Medical treatment for acute heart failure (AHF) has not changed substantially over the last four decades. Emergency department (ED)-based evidence for treatment is limited. Outcomes remain poor, with a 25% mortality or re-admission rate within 30days post discharge. Targeting pulmonary congestion, which can be objectively assessed using lung ultrasound (LUS), may be associated with improved outcomes. METHODS: BLUSHED-AHF is a multicenter, randomized, pilot trial designed to test whether a strategy of care that utilizes a LUS-driven treatment protocol outperforms usual care for reducing pulmonary congestion in the ED. We will randomize 130 ED patients with AHF across five sites to, a) a structured treatment strategy guided by LUS vs. b) a structured treatment strategy guided by usual care. LUS-guided care will continue until there are ≤15 B-lines on LUS or 6h post enrollment. The primary outcome is the proportion of patients with B-lines ≤ 15 at the conclusion of 6 h of management. Patients will continue to undergo serial LUS exams during hospitalization, to better understand the time course of pulmonary congestion. Follow up will occur through 90days, exploring days-alive-and-out-of-hospital between the two arms. The study is registered on ClinicalTrials.gov (NCT03136198). CONCLUSION: If successful, this pilot study will inform future, larger trial design on LUS driven therapy aimed at guiding treatment and improving outcomes in patients with AHF.

Diagnostic use of lung ultrasound compared to chest radiograph for suspected pneumonia in a resource-limited setting.

BACKGROUND: Lung ultrasound is an effective tool for diagnosing pneumonia in developed countries. Diagnostic accuracy in resource-limited countries where pneumonia is the leading cause of death is unknown. The objective of this study was to evaluate the sensitivity of bedside lung ultrasound compared to chest X-ray for pneumonia in adults presenting for emergency care in a low-income country. METHODS: Patients presenting to the emergency department with suspected pneumonia were evaluated with bedside lung ultrasound, single posterioranterior chest radiograph, and computed tomography (CT). Using CT as the gold standard, the sensitivity of lung ultrasound was compared to chest X-ray for the diagnosis of pneumonia using McNemar's test for paired samples. Diagnostic characteristics for each test were calculated. RESULTS: Of 62 patients included in the study, 44 (71%) were diagnosed with pneumonia by CT. Lung ultrasound demonstrated a sensitivity of 91% compared to chest X-ray which had a sensitivity of 73% (p = 0.01). Specificity of lung ultrasound and chest X-ray were 61 and 50% respectively. CONCLUSIONS: Bedside lung ultrasound demonstrated better sensitivity than chest X-ray for the diagnosis of pneumonia in Nepal. TRIAL REGISTRATION: ClinicalTrials.gov, registration number NCT02949141 . Registered 31 October 2016.

Extravasation Risk Using Ultrasound-guided Peripheral Intravenous Catheters for Computed Tomography Contrast Administration.

OBJECTIVE: Ultrasound-guided intravenous catheter (USGIV) insertion is increasingly being used for administration of intravenous (IV) contrast for computed tomography (CT) scans. The goal of this investigation was to evaluate the risk of contrast extravasation among patients receiving contrast through USGIV catheters. METHODS: A retrospective observational study of adult patients who underwent a contrast-enhanced CT scan at a tertiary care emergency department during a recent 64-month period was conducted. The unadjusted prevalence of contrast extravasation was compared between patients with an USGIV and those with a standard peripheral IV inserted without ultrasound. Then, a two-stage sampling design was used to select a subset of the population for a multivariable logistic regression model evaluating USGIVs as a risk factor for extravasation while adjusting for potential confounders. RESULTS: In total, 40,143 patients underwent a contrasted CT scan, including 364 (0.9%) who had contrast administered through an USGIV. Unadjusted prevalence of extravasation was 3.6% for contrast administration through USGIVs and 0.3% for standard IVs (relative risk = 13.9, 95% confidence interval [CI] = 7.9 to 24.6). After potential confounders were adjusted for, CT contrast administered through USGIVs was associated with extravasation (adjusted odds ratio = 8.6, 95% CI = 4.6 to 16.2). No patients required surgical management for contrast extravasation; one patient in the standard IV group was admitted for observation due to extravasation. CONCLUSIONS: Patients who received contrast for a CT scan through an USGIV had a higher risk of extravasation than those who received contrast through a standard peripheral IV. Clinicians should consider this extravasation risk when weighing the risks and benefits of a contrast-enhanced CT scan in a patient with USGIV vascular access.
