Tagle-Cornell MC, Novais BS, Wen S, Shipman JN, Mandale DR, Flom AP, Sahnan SK, Kriz LM, Alland ML, Bird CW, Naqvi TZ. Hand-Held Echocardiography by Advanced Practice Providers in Patients with Congestive Heart Failure. J Clin Med 2024; 13:312. [PMID: 38256445 PMCID: PMC10816508 DOI: 10.3390/jcm13020312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 12/22/2023] [Accepted: 01/02/2024] [Indexed: 01/24/2024] Open
Abstract
OBJECTIVES The performed hand-held echocardiography (HHE) was evaluated and interpreted by trained advanced practice providers (APPs) on hospitalized CHF patients for image quality and interpretation by comparing with expert echocardiographer and SE findings. BACKGROUND Congestive heart failure (CHF) is associated with increased hospital admissions and mortality. While a standard echocardiogram (SE) is the gold standard for cardiac assessment, it is not readily available. Hospitalized CHF patients require rapid assessment for expedited treatment. METHODS Over 6 months, five trained APPs performed HHE on hospitalized CHF patients and interpreted: (a) left ventricular (LV) size, (b) LV ejection fraction (LVEF), and (c) right atrial pressure (RAP). The study echocardiographer reviewed and blindly interpreted the HHE images and compared them with APPs and SE findings. Kappa statistics determined the degree of agreement between APPs and the study echocardiographer's interpretation of the HHE images and SE. RESULTS A total of 80 CHF patients (age 73 ± 14 years, 58% males; LVEF (by SE) 45 ± 19%; 36.3% body mass indexes ≥ 30 kg/m2) were enrolled. HHE interpretation by APPs had a good agreement for LVEF (kappa 0.79) with the study echocardiographer and SE (kappa 0.74) and a good agreement for RAP (kappa 0.67) with the study echocardiographer. The correlation between the absolute LVEF interpretation by the study echocardiographer on HHE and SE was r = 0.88 (p < 0.0001). CONCLUSIONS Trained APPs obtained diagnostic-quality HHE images and interpreted the LV function and RAP in CHF patients in good agreement with the study echocardiographer. LVEF by HHE correlated with LVEF by SE. Our study suggests trained APPs can use HHE to evaluate LVEF and RAP in CHF patients, leading to expedited and optimized treatment.

Clinical comparison of a handheld cardiac ultrasound device for the assessment of left ventricular function. THE INTERNATIONAL JOURNAL OF CARDIOVASCULAR IMAGING 2024; 40:55-64. [PMID: 37882957 DOI: 10.1007/s10554-023-02979-8] [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: 04/26/2023] [Accepted: 09/29/2023] [Indexed: 10/27/2023]
Abstract
PURPOSE Recently developed handheld ultrasound devices (HHUD) represent a promising method to evaluate the cardiovascular abnormalities at the point of care. However, this technology has not been rigorously evaluated. The aim of this study was to explore the correlation and the agreement between the LVEF (Left Ventricular Ejection Fraction) visually assessed by a moderately experienced sonographer using an HHUD compared to the routine LVEF assessment performed at the Echocardiography Laboratory. METHODS This was a prospective single center study which enrolled 120 adult inpatients and outpatients referred for a comprehensive Echocardiography (EC). RESULTS The mean age of the patients was 69.9 ± 12.5 years. There were 47 females (39.2%). The R-squared was r 0.94 (p < 0.0001) and the ICC was 0.93 (IC 95% 0.91-0.95, p ≤ 0.0001). The Bland-Altman plot showed limits of agreement (LOA): Upper LOA 10.61 and Lower LOA - 8.95. The overall agreement on the LVEF assessment when it was stratified as "normal" or "reduced" was 89.1%, with a kappa of 0.77 (p < 0.0001). When the LVEF was classified as "normal", "mildly reduced", "moderately reduced", or "severely reduced," the kappa was 0.77 (p < 0.0001). The kappa between the HHUD EC and the comprehensive EC for the detection of RWMAs in the territories supplied by the LAD, LCX and RCA was 0.85, 0.73 and 0.85, respectively. CONCLUSION With current HHUD, an averagely experienced operator can accurately bedside visual estimate the LVEF. This may facilitate the incorporation of this technology in daily clinical practice improving the management of patients.

Integrative review of electrocardiographic characteristics in patients with reduced, mildly reduced, and preserved heart failure. Heart Lung 2024; 63:142-158.

Abstract
INTRODUCTION Electrocardiographic (ECG) changes in heart failure with reduced, mildly reduced, and preserved ejection fractions can be critical in clinical assessment while waiting to perform echocardiograms or when it is unavailable. This integrative review aimed to identify ECG characteristics among hospitalized patients demonstrating three types of heart failure during acute decompensation. METHODS We searched an electronic database of PubMed, Web of Science, EMBASE, Scopus, Google Scholar, and ClinicalTrials.gov using medical subject headings (MeSH) terms and keywords. Sixteen studies were synthesized and reported. RESULTS Heart failure with reduced ejection fraction (HFrEF) was more common in men, comorbid with coronary artery diseases and diabetes mellitus, higher BNP/Pro-BNP, wide QRS, and left bundle branch block on ECG. On average, clients with heart failure with preserved ejection fraction (HFpEF) were older and more likely to have a history of atrial fibrillation, valvular heart diseases, hypertension, chronic obstructive pulmonary, and atrial fibrillation (AF) on ECG. Patients with mildly reduced (HFmrEF) were more similar to HFpEF in older patients, comorbid with hypertension, AF and valvular diseases, and AF on ECG. CONCLUSIONS ECG characteristics might be related to left ventricular ejection fraction. Demographics, BNP/Pro-BNP, and ECG changes might help differentiate different heart failure types. Therefore, ECG might be a prognostic tool while caring for heart failure patients when highly skilled resources are unavailable. These identified ECG characteristics help generate research hypotheses and warrant validation in future research.

Abstract
Point-of-care ultrasound (POCUS) is a useful imaging tool for the diagnosis and monitoring of cardiac emergencies. Unlike complete echocardiography, POCUS is a time-sensitive examination involving a subset of targeted thoracic ultrasound views to identify abnormalities of the heart, lungs, pleural space, and caudal vena cava. When integrated with other clinical information, POCUS can be helpful in the diagnosis of left-sided and right-sided congestive heart failure, pericardial effusion and tamponade, and severe pulmonary hypertension and can help clinicians monitor resolution or recurrence of these conditions.

Abstract
A significant proportion of patients experience delays in the diagnosis of heart failure due to the non-specific signs and symptoms of the syndrome. Diagnostic tools such as measurement of natriuretic peptide concentrations are fundamentally important when screening for heart failure, yet are frequently under-utilized. This clinical consensus statement provides a diagnostic framework for general practitioners and non-cardiology community-based physicians to recognize, investigate and risk-stratify patients presenting in the community with possible heart failure.

Abstract
Heart failure with reduced ejection fraction (HFrEF) is considered a major health care problem with frequent decompensations, high hospitalization and mortality rates. In severe heart failure (HF), the symptoms are refractory to medical treatment and require advanced therapeutic strategies. Early recognition of HF sub- and decompensation is the cornerstone of the timely treatment intensification and, therefore, improvement in the prognosis. Echocardiography is the gold standard for the assessment of systolic and diastolic functions. It allows one to obtain accurate and non-invasive measurements of the ventricular function in HF. In severely compromised HF patients, advanced cardiovascular ultrasound modalities may provide a better assessment of intracardiac hemodynamic changes and subclinical congestion. Particularly, cardiovascular and lung ultrasound allow us to make a more accurate diagnosis of subclinical congestion in HFrEF. The aim of this review was to summarize the advantages and limitations of the currently available ultrasound modalities in the ambulatory monitoring of patients with HFrEF.

Abstract
We sought to determine the cardiac ultrasound view of greatest quality using a machine learning (ML) approach on a cohort of transthoracic echocardiograms (TTE) with abnormal left ventricular (LV) systolic function. We utilize an ML model to determine the TTE view of highest quality when scanned by sonographers. A random sample of TTEs with reported LV dysfunction from 09/25/2017-01/15/2019 were downloaded from the regional database. Component video files were analyzed using ML models that jointly classified view and image quality. The model consisted of convolutional layers for extracting spatial features and Long Short-term Memory units to temporally aggregate the frame-wise spatial embeddings. We report the view-specific quality scores for each TTE. Pair-wise comparisons amongst views were performed with Wilcoxon signed-rank test. Of 1,145 TTEs analyzed by the ML model, 74.5% were from males and mean LV ejection fraction was 43.1 ± 9.9%. Maximum quality score was best for the apical 4 chamber (AP4) view (70.6 ± 13.9%, p<0.001 compared to all other views) and worst for the apical 2 chamber (AP2) view (60.4 ± 15.4%, p<0.001 for all views except parasternal short-axis view at mitral/papillary muscle level, PSAX M/PM). In TTEs scanned by professional sonographers, the view with greatest ML-derived quality was the AP4 view.

Abstract
BACKGROUND Goal directed point of care ultrasound (POCUS) is a bedside tool to assist with clinical diagnosis. We examined the impact of POCUS performed by consulting cardiologist (CC) during initial cardiology consult on clinical management and downstream testing. METHODS Sixty-nine study patients (pts) seen in a general cardiology outpatient clinic of a tertiary center by an expert imaging CC were compared to a control group of 65 pts seen by three different CCs without POCUS during the same time-period, in whom the first standard echo (SE) was performed after the initial visit. RESULTS Baseline characteristics were similar between the two groups for age, cardiac risk factors, and referral diagnoses. Echo findings on POCUS and by SE (mean delay of 17.2 days after visit) in the control group were comparable for RV size and function and for valvular heart disease. More patients with lower LVEF, higher LV filling pressures, new regional wall motion abnormalities, and increased aortic root size were present among POCUS group resulting in greater yield of echo abnormalities. There were more cardiovascular medication changes at the first visit (15.3% vs. 5.7%, p < .01), less referral for noninvasive stress testing (10% vs. 29%, p < .01), more advanced cardiac testing and subspecialty referrals (29% vs. 18% pts, p = .06), in the study compared to the control group after cardiology visit. CONCLUSION POCUS at time of consultation detects more abnormal echo findings, results in more medication adjustments, less referral for noninvasive stress testing, earlier referral for advanced cardiac diagnostic imaging, and subspecialty cardiac referrals.

A Tool to Assess Competence in Critical Care Ultrasound Based on Entrustable Professional Activities. ATS Sch 2023; 4:61-75.

Abstract
Background Existing assessment tools for competence in critical care ultrasound (CCUS) have limited scope and interrupt clinical workflow. The framework of entrustable professional activities (EPAs) is well suited to developing an assessment tool that is comprehensive and readily integrated into the intensive care unit (ICU) training environment. Objective This study sought to design an EPA-based tool to assess competence in CCUS for pulmonary and critical care fellows and to assess the validity and reliability of the tool. Methods Eight experts in CCUS met to define the core EPAs for CCUS. A nominal group technique was used to reach consensus. An assessment tool was created based on the EPAs with a modified Ottawa entrustability scale. Trained faculty evaluated pulmonary and critical care fellows using this tool in the ICU over a 6-month study period at a single institution. An assessment of validity of the EPA-based tool is made with four sources of validity evidence: content, response process, reliability, and relation to other variables. Reliability and response process data were generated using generalizability theory analysis to estimate sources of variance in entrustment scores. Analysis of response process validity and validity by relation to other variables was performed using regression models. Results Fifty-four assessments were recorded during the study period, conducted on 23 trainees by 13 faculty. Content validity of the tool was demonstrated using expert consensus and published guidelines from critical care societies to define the EPAs. Response process validity was demonstrated by the low variance in entrustment scores due to evaluators (0.086 or 6%) and high agreement between score and trainee self-assessment (regression coefficient, 0.82; P < 0.0001). Reliability was demonstrated by the high "true" variance in entrustment score attributable to the trainee: 0.674 or 45%. Validity by relation to other variables was demonstrated using regression analysis to show correlation between entrustment score and the number of times a fellow has performed an EPA (regression coefficient, 0.023; P < 0.0001). Conclusion An EPA-based assessment tool for competence in CCUS was created. We obtained sufficient validity evidence on three of the diagnostic EPAs. Procedural EPAs were infrequently assessed, limiting generalizability in this subgroup.

Abstract
Limited views are often obtained in the setting of cardiac ultrasound, however, the likelihood of missing left ventricular (LV) dysfunction based on a single view is not known. We sought to determine the echo views that were least likely to miss LV systolic dysfunction in consecutive transthoracic echocardiograms (TTEs). Structured data from TTEs performed at 2 hospitals from September 25, 2017, to January 15, 2019, were screened. Studies of interest were those with reported LV dysfunction. Views evaluated were the parasternal long-axis (PLAX), parasternal-short axis at mitral (PSAX M), papillary muscle (PSAX PM), and apical (PSAX A) levels, apical 2 (AP2), apical 3 (AP3), and apical 4 (AP4) chamber views. The probability that a view contained at least 1 abnormal segment was determined and analyzed with McNemar's test for 21 adjusted pair-wise comparisons. There were 4102 TTE studies included for analysis. TTEs on males comprised 72.7% of studies with a mean LV ejection fraction of 42.8 ± 9.7%. The echo view with the greatest likelihood of encompassing an abnormal segment was the AP2 view with a prevalence of 93.4% (p < 0.001, compared to all other views). The PLAX view performed the worst with a prevalence of 82.5% (p < 0.015, compared to all other views). The best parasternal view for the detection of abnormality was the PSAX PM view at 90.4%. In conclusions, a single echo view will contain abnormal segments > 82% of the time in the setting of LV systolic dysfunction, with a prevalence of up to 93.4% in the apical windows.

Handheld Echocardiography in a Clinical Practice Scenario: Concordances Compared to Standard Echocardiographic Reports. J Cardiovasc Imaging 2022; 30:25-34. [PMID: 35086166 PMCID: PMC8792719 DOI: 10.4250/jcvi.2020.0241] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 04/12/2021] [Accepted: 05/10/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND The purpose of this study was to assess the utility of a handheld device (HH) used during common daily practice and its agreement with the results of a standard echocardiography study (STD) performed by experienced sonographers and echocardiographer. METHODS A prospective follow-up was conducted in an adult outpatient echocardiography clinic. Experienced sonographers performed the STD and an experienced echocardiographer performed the HH. STD included 2-dimensional images, Doppler and hemodynamics analysis. Hemodynamic assessment was not performed with the HH device because the HH does not include such technology. The images were interpreted by blinded echocardiographers, and the agreement between the reports was analyzed. RESULTS A total of 108 patients were included; and the concordance for left ventricle (LV) ejection fraction (EF), wall motion score index, LV and right ventricle (RV) function, RV size, and mitral and aortic stenosis was excellent with κ values greater than 0.80. Wall motion abnormalities had good concordance (κ value 0.78). The agreement for LV hypertrophy, mitral and aortic regurgitation was moderate, and tricuspid and pulmonary regurgitation agreements were low (κ values of 0.26 and 0.25, respectively). CONCLUSIONS In a daily practice scenario with experienced hands, HH demonstrated good correlation for most echocardiography indications, such as ventricular size and function assessment and stenosis valve lesion analyses.

Abstract
IMPORTANCE There are accumulating data about the utility of diagnostic multiorgan focused clinical ultrasonography (FCU) in the assessment of patients admitted with cardiopulmonary symptoms. OBJECTIVE To determine whether adding multiorgan FCU to the initial clinical evaluation of patients admitted with cardiopulmonary symptoms reduces hospital length of stay, hospital readmissions, and in-hospital costs. DESIGN, SETTING, AND PARTICIPANTS This is a prospective, parallel-group, superiority, randomized clinical trial with a 1:1 allocation ratio. The study was conducted at The Royal Melbourne Hospital, a tertiary public hospital located in Melbourne, Victoria, Australia. Adults aged 18 years or older admitted to the internal medicine ward with a cardiopulmonary diagnosis were enrolled between September 2018 and December 2019 and were followed up until hospital discharge. Data analysis was performed from August 2020 to January 2021. INTERVENTIONS The intervention involved an internal medicine physician-performed heart, lung, and 2-point vein compression FCU in addition to standard clinical evaluation. MAIN OUTCOMES AND MEASURES The primary outcome was the difference in the mean length of hospital stay, defined as the number of hours from admission to the internal medicine ward to hospital discharge. A difference of 24 hours was defined as clinically important. Secondary outcomes included hospital readmissions at 30 days and hospital care costs. RESULTS A total of 250 participants were enrolled and 2 were excluded, leaving 248 participants (mean [SD] age, 80.1 [11.0] years; 121 women [48.7%]) in the final analysis. There were 124 patients in the intervention group and 124 patients in the control group. The most common initial diagnoses were acute decompensated heart failure (113 patients [45.5%]), pneumonia (45 patients [18.1%]), and exacerbated chronic pulmonary disease (32 patients [12.9%]). The length of hospital stay was 113.4 hours (95% CI, 91.7-135.1 hours) in the FCU group and 125.3 hours (95% CI, 101.7-148.8 hours) in the control group (P = .53). The 30-day readmission rate was not different between groups (FCU vs control, 20 of 124 patients [16.1%] vs 15 of 124 patients [12.0%]), nor were total in-hospital costs (FCU vs control, A$7831.1 [95% CI, A$5586.1-A$10 076.1] vs A$7895.7 [95% CI, A$6385.9-A$9.405.5]). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, adult patients admitted to an internal medicine ward with a cardiopulmonary diagnosis, who underwent multiorgan FCU of the heart, lungs, and lower extremities veins during their initial clinical assessment, did not have a shorter hospital length of stay by more than 24 hours, compared with patients who received standard care.

Accuracy and reliability of focused echocardiography in patients with Chagas disease from endemic areas: SaMi-Trop cohort study. PLoS One 2021; 16:e0258767. [PMID: 34735475 PMCID: PMC8568132 DOI: 10.1371/journal.pone.0258767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Accepted: 10/05/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Chagas disease remains a major cause of cardiovascular death in endemic areas. Focused echocardiography (FoCUS) is a point-of-care means of assessing cardiac function which can be useful for the diagnosis of cardiac involvement. OBJECTIVE This study aims evaluating the characteristics of validity and reliability of FoCUS applied on Chagas disease patients. METHODS Patients with Chagas disease coming from an endemic area were selected from a large cohort (SaMi-Trop). A simplified echocardiogram with only three images was extracted from the conventional echocardiogram performed in this cohort. The images were evaluated by an observer who was blinded to the clinical and echocardiographic data, to determine the accuracy and reliability of FoCUS for cardiac assessment. The analysis constituted of 5 prespecified variables, dichotomized in absence or presence: left ventricular (LV) size and systolic function, right ventricular (RV) size and systolic function, and LV aneurysm. RESULTS We included 725 patients with a mean age of 63.4 ± 12.3 years, 483 (67%) female. Abnormal electrocardiogram was observed in 81.5% of the patients. Left and right ventricular dysfunctions were found in 103 (14%) and 49 (7%) of the patients, respectively. Sensitivity, specificity, positive predictive value and negative predictive value were 84%, 94%, 70% and 97% for LV enlargement and 81%, 93%, 68% and 97% for LV systolic dysfunction, respectively, and 46%, 99%, 60% and 98% for RV dilatation, and 37%, 100%, 100% and 96% for RV dysfunction, respectively. Inter and intraobserver agreement were 61% and 87% for LV enlargement and 63% and 92% for LV dysfunction, respectively, and 50% and 49% for RV size and 46% and 79% for RV dysfunction, respectively. LV apical aneurysm was found in 45 patients (6.2%) with the lowest sensitivity of FoCUS study (11%; 95% CI 2-28%). CONCLUSIONS FoCUS showed satisfactory values of validity and reliability for assessment of cardiac chambers in patients with Chagas disease, except for apical aneurysm. This tool can identify heart disease with potential impact on patient management in the limited-resource setting.

Diagnostic accuracy of handheld cardiac ultrasound device for assessment of left ventricular structure and function: systematic review and meta-analysis. Heart 2021; 107:1826-1834. [PMID: 34362772 PMCID: PMC8562308 DOI: 10.1136/heartjnl-2021-319561] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 07/12/2021] [Indexed: 12/02/2022] Open
Abstract
Objective Handheld ultrasound devices (HUD) has diagnostic value in the assessment of patients with suspected left ventricular (LV) dysfunction. This meta-analysis evaluates the diagnostic ability of HUD compared with transthoracic echocardiography (TTE) and assesses the importance of operator experience. Methods MEDLINE and EMBASE databases were searched in October 2020. Diagnostic studies using HUD and TTE imaging to determine LV dysfunction were included. Pooled sensitivities and specificities, and summary receiver operating characteristic curves were used to determine the diagnostic ability of HUD and evaluate the impact of operator experience on test accuracy. Results Thirty-three studies with 6062 participants were included in the meta-analysis. Experienced operators could predict reduced LV ejection fraction (LVEF), wall motion abnormality (WMA), LV dilatation and LV hypertrophy with pooled sensitivities of 88%, 85%, 89% and 85%, respectively, and pooled specificities of 96%, 95%, 98% and 91%, respectively. Non-experienced operators are able to detect cardiac abnormalities with reasonable sensitivity and specificity. There was a significant difference in the diagnostic accuracy between experienced and inexperienced users in LV dilatation, LVEF (moderate/severe) and WMA. The diagnostic OR for LVEF (moderate/severe), LV dilatation and WMA in an experienced hand was 276 (95% CI 58 to 1320), 225 (95% CI 87 to 578) and 90 (95% CI 31 to 265), respectively, compared with 41 (95% CI 18 to 94), 45 (95% CI 16 to 123) and 28 (95% CI 20 to 41), respectively, for inexperienced users. Conclusion This meta-analysis is the first to establish HUD as a powerful modality for predicting LV size and function. Experienced operators are able to accurately diagnose cardiac disease using HUD. A cautious, supervised approach should be implemented when imaging is performed by inexperienced users. This study provides a strong rationale for considering HUD as an auxiliary tool to physical examination in secondary care, to aid clinical decision making when considering referral for TTE.

Feasibility of point-of-care cardiac ultrasound performed by clinicians at health centers in Tanzania. BMC Cardiovasc Disord 2021; 21:239. [PMID: 33980177 PMCID: PMC8117304 DOI: 10.1186/s12872-021-02045-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Accepted: 04/29/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Point-of-care cardiac ultrasound (cardiac POCUS) has potential to become a useful tool for improving cardiovascular care in Tanzania. We conducted a pilot program to train clinicians at peripheral health centers to obtain and interpret focused cardiac POCUS examinations using a hand-held portable device. METHODS Over a 5-day period, didactic and experiential methods were used to train clinicians to conduct a pre-specified scanning protocol and recognize key pathologies. Pre- and post-training knowledge and post-training image acquisition competency were assessed. In their usual clinical practices, trainees then scanned patients with cardiovascular signs/symptoms, recorded a pre-specified set of images for each scan, and documented their interpretation as to presence or absence of key pathologies on a case report form. A cardiologist subsequently reviewed all images, graded them for image quality, and then documented their interpretation of key pathologies in a blinded fashion; the cardiologist interpretation was considered the gold standard. RESULTS 8 trainees (6 Clinical Officers, 1 Assistant Medical Officer, and 1 Medical Doctor) initiated and completed the training. Trainees subsequently performed a total of 429 cardiac POCUS examinations in their clinical practices over a 9 week period. Stratified by trainee, the median percent of images that were of sufficient quality to be interpretable was 76.7% (range 18.0-94.2%). For five of eight trainees, 75% or more of images were interpretable. For detection of pre-specified key pathologies, kappa statistics for agreement between trainee and cardiologist ranged from - 0.03 (no agreement) for detection of pericardial effusion to 0.42 (moderate agreement) for detection of tricuspid valve regurgitation. Mean kappa values across the key pathologies varied by trainee from 0 (no agreement) to 0.32 (fair agreement). CONCLUSIONS The 5-day training program was sufficient to train most clinicians to obtain basic cardiac images but not to accurately interpret them. Proficiency in image interpretation may require a more intensive training program.

Abstract
Kidney disease patients have a high prevalence of cardiovascular morbidity and mortality. It can be challenging to adequately assess their cardiovascular status based on physical examination alone. Cardiac ultrasound has proven to be a powerful tool to accomplish this objective and is increasingly being adopted by noncardiologists to augment their skills and expedite clinical decision-making. With the advent of inexpensive and portable ultrasound equipment, simplified protocols, and focused training, it is becoming easier to master basic cardiac ultrasound techniques. After a short course of training in focused cardiac ultrasound, nephrologists can quickly and reliably assess ventricular size and function, detect clinically relevant pericardial effusion and volume status in their patients. Additional training in Doppler ultrasound can extend their capability to measure cardiac output, right ventricular systolic pressure, and diastolic dysfunction. This information can be instrumental in effectively managing patients in inpatient, office, and dialysis unit settings. The purpose of this review is to highlight the importance and feasibility of incorporating cardiac ultrasound in nephrology practice, discuss the principles of basic and Doppler ultrasound modalities and their clinical utility from a nephrologist's perspective.

Abstract
BACKGROUND There is insufficient knowledge about how personal access to handheld ultrasound devices (HUDs) improves trainee learning with point-of-care ultrasound (POCUS). OBJECTIVE To assess whether HUDs, alongside a yearlong lecture series, improved trainee POCUS usage and ability to acquire images. METHODS Internal medicine intern physicians (n = 47) at a single institution from 2017 to 2018 were randomized 1:1 to receive personal HUDs (n = 24) for patient care/self-directed learning vs no-HUDs (n = 23). All interns received a repeated lecture series on cardiac, thoracic, and abdominal POCUS. Main outcome measures included self-reported HUD usage rates and post-intervention assessment scores using the Rapid Assessment of Competency in Echocardiography (RACE) scale between HUD and no-HUD groups. RESULTS HUD interns reported performing POCUS assessments on patients a mean 6.8 (SD 2.2) times per week vs 6.4 (SD 2.9) times per week in non-HUD arm (P = .66). There was no relationship between the number of self-reported examinations per week and a trainee's post-intervention RACE score (rho = 0.022, P = .95). HUD interns did not have significantly higher post-intervention RACE scores (median HUD score 17.0 vs no-HUD score 17.8; P = .72). Trainee confidence with cardiac POCUS did not correlate with RACE scores. CONCLUSIONS Personal HUDs without direct supervision did not increase the amount of POCUS usage or improve interns' acquisition abilities. Interns who reported performing more examinations per week did not have higher RACE scores. Improved HUD access and lectures without additional feedback may not improve POCUS mastery.

Abstract
BACKGROUND In the last years, ultrasound technology has entered clinical practice as a tank and today, it has also allowed no-cardiologists to extend their medical examination without needing to call the consultant and having a good profile of diagnostic accuracy. The ultrasound bedside does not replace the consultant, but it allows not to perform inappropriate consultations with more savings for hospitals. OBJECTIVE The aim was to review the recently published literature to inform the clinician about the most up to date management of use bedside echography in the emergency setting. In this short review, we focused on two types of syndromes, no traumatic- hypotension and dyspnea, common to the three holistic disciplines of medicine, showing the main and basic questions and answers that ultrasound can give us for rapid identification of the problems. METHODS We conducted a systematic review using Pubmed/Medline, Ovid/Willey and Cochrane Library, combining key terms such as "cardiac ultrasound, "cardiac diseases", "emergency medicine", "pocus", "dyspnea", " hypotension". We selected the most relevant clinical trials and review articles (excluding case reports) published in the last 19 years and in our opinion, 59 publications appeared to be the best choice according to the PRISMA statement. In additional papers identified from individual article reference lists were also included. CONCLUSION Recent studies have shown a promise in establishing best practices for evaluation of heart, lung abdomen and deep vessels At the moment, bedside US is widely used in an integrated ultrasound vision just like the holistic view have internal medicine, intensive care and emergency medicine and many medical schools in Europe and the USA are inserting ultrasonography into the core curriculum, but we still have to find a standard method for the training program for minimum competence acquisition.

Abstract
Background: Focused cardiac ultrasound (FCU) is a safe and efficient diagnostic intervention for internal medicine physicians. FCU is a highly teachable skill, but is used in routine cardiac assessment in only 20% of surveyed training programs.We developed an FCU curriculum for internal medicine residents and an assessment tool to evaluate the impact of the curriculum on trainee knowledge and confidence. Methods: Internal medicine residents rotating through clinical cardiology services underwent 30 minutes of didactic and 60 minutes of hands-on teaching on acquisition and interpretation of FCU. A 20 item pre and post-curriculum online survey was administered (November 2018-December 2019) to assess confidence and knowledge in FCU. Results: 79 of 116 (68%) residents completed the pre-survey and 50 completed the post-survey, of whom 34 received the curriculum. The mean change in confidence score in those who received versus did not receive the curriculum was 0.99 versus 0.39 (p=0.046) on a 5-point Likert scale. Among 33 residents who had paired pre- and post-surveys the mean change in confidence score was 1.2 versus 0.85 (p<0.001) in those who received versus did not receive the curriculum. The mean increase in knowledge score was 13% versus 7% respectively (p<0.0001). Conclusions: We instituted a novel curriculum for internal medicine residents to gain experience in image acquisition and interpretation. Both confidence and knowledge in FCU improved following the curriculum, indicating that this is a highly teachable skill. Additional analysis of the of the FCU study images will be useful for informing future interventions.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2020; 39:2151-2164. [PMID: 32426900 DOI: 10.1002/jum.15324] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 04/03/2020] [Accepted: 04/15/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVES A rapid, reliable quantitative assessment of left ventricular systolic and diastolic function is important for patient treatment in urgent and dynamic settings. Quantification of annular velocities based on a single 2-dimensional image loop, rather than on Doppler velocities, could be useful in point-of-care or focused cardiac ultrasound. We hypothesized that novel speckle-tracking-based mitral annular velocities would correlate with reference standard tissue Doppler imaging (TDI) velocities in a focused cardiac ultrasound-esque setting. METHODS Two echocardiographers each performed transthoracic echocardiographic measurements before and after induction of anesthesia in supine patients undergoing cardiac surgery. Speckle-tracking echocardiography (STE)-based systolic (S'STE ) and diastolic (E'STE and A'STE ) velocities were compared to TDI and global longitudinal strain/strain rate. We also compared mitral annular displacement by speckle tracking with M-mode imaging. RESULTS Twenty-five patients were included and examined in both preinduction and postinduction states. Speckle-tracking-based velocities correlated with TDI measurements in both states (S', r = 0.73 and 0.76; E', r = 0.87 and 0.65; and A', r = 0.65 and 0.73), showing a mean bias of 25% to 30% of the reference standard measurement. The correlation of S'STE with strain and the strain rate (S-wave) and E'STE with the strain rate (E-wave) was good in awake, spontaneously breathing patients but was less strong in the ventilated state. Similarly, displacement by speckle tracking correlated with M-mode measurements in both states (r = 0.91 and 0.84). Measurements required medians of 31 and 34 seconds; reproducibility was acceptable for S'STE and E'STE . CONCLUSIONS Speckle-tracking-based mitral annular velocities and displacement correlate well with conventional measures as well as with deformation imaging. They may be clinically useful in rapidly assessing both systolic and diastolic function from a single 2-dimensional image loop.

Abstract
Purpose of the Review Point-of-care ultrasound using small ultrasound devices has expanded beyond emergency and critical care medicine to many other subspecialties. Awareness of the strengths and limitations of the technology and knowledge of the appropriate settings and common indications for point-of-care ultrasound is important. Recent Findings Point-of-care ultrasound is widely embraced as an extension of the physical exam and is employed in acute care and medical education settings. Echocardiography laboratories involved in education must individualize training to the intended scope of practice of the user. Advances in artificial intelligence may assist in image acquisition and interpretation by novice users. Summary Point-of-care ultrasound is widely available in a variety of clinical settings. The field has advanced substantially in the past 2 decades and will likely continue to expand with advancement in technology, reduced cost, and improved opportunities to assist new users.

Abstract
Point-of-care ultrasound (POCUS) improves both the sensitivity and specificity with which clinicians can make a variety of diagnoses at the bedside from abdominal aortic aneurysm to kidney stones. In outpatient clinics, urgent care centers, and emergency departments, where ultrasound imaging may be delayed by hours or even days, the use of POCUS can be very helpful. We believe that POCUS facilitates both the triage of patients and provides diagnostic information quickly. We hope to advance the use of POCUS in the primary care setting and have reviewed six sonographic topics where we believe ultrasound can be of immense assistance to the physician in the outpatient setting.

Abstract
As the availability of portable echocardiographic equipment is becoming more and more widespread, physicians can add a powerful tool to their bedside examination skills, thus helping them to more effectively face the growing complexity of patients admitted to internal medicine departments or the emergency room. Focused cardiac ultrasound (FoCUS) can be defined as a goal-directed, simplified, qualitative examination performed at the bedside using portable echocardiographic devices. FoCUS is not meant to be a substitute for a standard 2D color Doppler echocardiographic examination. Nevertheless, it can provide rapid and reliable information when limited to basic questions, even when performed by non-cardiologists with brief training. Furthermore, a focused cardiac ultrasound examination maximizes its diagnostic role when integrated with an ultrasonographic assessment of the lung, abdomen and deep veins, in a multisystem approach that is particularly dear to internists. In this article, we will focus on the specific targets of a focused cardiac ultrasound examination, as well as the most common pitfalls that can be encountered in ultrasonographic practice. We will also address the application of FoCUS in the management of two typical scenarios in clinical practice, such as dyspnea and non-post-traumatic hypotension.

Abstract
Transthoracic echocardiography is the standard of care in anatomic and functional cardiovascular assessment; however, focused cardiac ultrasound (FoCUS) performed with portable ultrasound equipment is increasingly being used as an adjunct to comprehensive history and physical examination. FoCUS assessments, unlike formal echocardiography, are intended to assist physicians in answering explicit clinical questions with a narrow differential diagnosis in real time. Over the past decade, a growing body of literature has repeatedly shown the value that FoCUS adds to clinical evaluation. Specifically, FoCUS improves point-of-care diagnostic accuracy, which in turn modifies treatment plans, decreases time to diagnosis, and reduces resource utilization. Although less robust, there is also evidence showing improvement in clinical outcomes. Based on this evidence, clinicians, training programs, and clinical societies have embraced FoCUS as a tool to complement bedside patient evaluation. Herein, we review the evidence for FoCUS in clinical practice, specifically evaluating the diagnostic accuracy, the impact on clinical decision-making, and the effect on clinical outcomes.

Abstract
Background: Focused cardiac ultrasound (FCU) is widely used by healthcare providers to answer specific questions about cardiac structure and function at the bedside. Currently, no widely accepted FCU image acquisition checklist exists to assess learners with varying skill levels from different specialties. Objective: The primary objective of this project was to develop a consensus-based FCU image acquisition checklist using a multispecialty group of point-of-care ultrasound (POCUS) experts. Methods: The essential components of an FCU examination were identified on the basis of published recommendations from echocardiography and international ultrasound societies. A checklist of the essential components of an FCU examination was drafted. A panel of POCUS experts from different medical specialties in the United States and Canada was convened to vote on each checklist item by answering two questions: 1) Is this item important to include in a checklist of essential FCU skills applicable to any medical specialty? and 2) Should the learner be required to successfully complete this item to be considered competent? A modified Delphi approach was used to assess the level of agreement for each checklist item during four rounds of voting. Checklist items that achieved an agreement of 80% or greater were included in the final checklist. Results: Thirty-one POCUS experts from seven different medical specialties voted on sixty-five items to be included in the FCU image acquisition assessment tool. The majority of POCUS experts (61%) completed all four rounds of voting. During the first round of voting, 59 items reached consensus, and after revision and revoting, an additional 3 items achieved 80% or greater consensus. A total of 62 items were included in the final checklist, and 57 items reached consensus as a requirement for demonstration of competency. Conclusion: We have developed a multispecialty, consensus-based FCU image acquisition checklist that may be used to assess the skills of learners from different specialties. Future steps include studies to develop additional validity evidence for the use of the FCU assessment tool and to evaluate its utility for the translation of skills into clinical practice.

Abstract
The advent of portable devices in the early 80s has brought ultrasonography to the patient's bedside. Currently referred to as 'point of care ultrasonography' (POCUS), it has become an essential tool for clinicians. Initially developed in the emergency and critical care settings, POCUS has gained increasing importance in internal medicine wards in the last decade, with both its growing diagnostic accuracy and portability making POCUS an optimal instrument for everyday clinical assessment and procedures. There is large body of evidence to confirm POCUS' superiority when compared to clinical examination and standard X-ray imaging in a variety of clinical situations. On the contrary, only few indications, such as procedural guidance, have a proven additional benefit for patients. Since POCUS is highly user-dependent, pre- and post-graduate curricula are needed and the range of use should be clearly defined. This review focuses on trends and perspectives of POCUS in the management of diseases frequently encountered in emergency and internal medicine. In addition, questions are raised regarding the teaching and supervision of POCUS needing to be addressed in the near future.

Abstract
With continuing advancements in software, electronics, and miniaturization, ultrasound (US) is quickly becoming an everyday tool of numerous medical specialties. With the advent of new handheld and other small-scale units, physicians have a tool to obtain on demand imaging without exposing the patient to ionizing radiation in the pocket of their white coat. As such, the need for competency in US is increasing. Currently, US training primarily occurs in residency, with only a handful of institutions incorporating US into the undergraduate medical education (UME) curriculum. To date, no ideal method has been presented (Amini et al., Intern Emerg Med. 10(5):613-8, 2015; Wilson et al., J Ultrasound Med. 36(2):321-5, 2017). Presented herein is a method for the addition of US training into the undergraduate medical curriculum. Utilizing a co-enrolled course format, 6 medical students were given basic training in the history and physics of US, echocardiography (ECHO), right upper quadrant (RUQ) ultrasound, focused assessment with sonography for trauma (FAST), and extended (eFAST) exams, vascular access techniques, and MSK ultrasound over 17 sessions. Students theoretical knowledge was assessed during team-based learning (TBL) sessions in an individual and group readiness assurance test (IRAT/GRAT) format. Students' practical skill was assessed in an objective structured clinical examination (OSCE) format. Students demonstrated notable proficiency with the US unit and were able to conduct both US-guided peripheral and central vascular access techniques. Furthermore, students were able to identify 80% or more of the required structures for the RUQ, ECHO, and eFAST US exams.

Abstract
BACKGROUND Little is known about how to effectively train residents with point-of-care ultrasonography (POCUS) despite increasing usage. OBJECTIVE This study aimed to assess whether handheld ultrasound devices (HUDs), alongside a year-long lecture series, improved trainee image interpretation skills with POCUS. METHODS Internal medicine intern physicians (N = 149) at a single academic institution from 2016 to 2018 participated in the study. The 2017 interns (n = 47) were randomized 1:1 to receive personal HUDs (n = 24) for patient care vs no-HUDs (n = 23). All 2017 interns received a repeated lecture series regarding cardiac, thoracic, and abdominal POCUS. Interns were assessed on their ability to interpret POCUS images of normal/abnormal findings. The primary outcome was the difference in end-of-the-year assessment scores between interns randomized to receive HUDs vs not. Secondary outcomes included trainee scores after repeating lectures and confidence with POCUS. Intern scores were also compared with historical (2016, N = 50) and contemporaneous (2018, N = 52) controls who received no lectures. RESULTS Interns randomized to HUDs did not have significantly higher image interpretation scores (median HUD score: 0.84 vs no-HUD score: 0.84; P = .86). However, HUD interns felt more confident in their abilities. The 2017 cohort had higher scores (median 0.84), compared with the 2016 historical control (median 0.71; P = .001) and 2018 contemporaneous control (median 0.48; P < .001). Assessment scores improved after first-time exposure to the lecture series, while repeated lectures did not improve scores. CONCLUSIONS Despite feeling more confident, personalized HUDs did not improve interns' POCUS-related knowledge or interpretive ability. Repeated lecture exposure without further opportunities for deliberate practice may not be beneficial for mastering POCUS.

Abstract
Background: Many internal medicine residency programs have incorporated ultrasonography into their curriculum; however, its integration with physical examination skills teaching at a graduate medical level is scarce. The program's aim is to create a reproducible elective that combines physical exam and bedside ultrasound as a method for augmenting residents' knowledge and competence in these techniques with the ultimate goal of improving patient care. Methods: We designed and implemented a two-week elective rotation for senior internal medicine residents, combining evidence-based physical examination with diagnostic bedside ultrasonography. The rotation took place in an inpatient setting at Denver Health Hospital. Program evaluation data was collected data between February 2016 to March 2019. IRB approval was waived. Results: Since its inception in 2016, 19 residents completed the rotation. Residents performed a pre-test and a post-test under direct observation by course faculty. Each resident was measured on the ability to perform pre-determined physical exam and point-of-care ultrasound (POCUS) skills. In the pre-test, participants correctly performed an average of 40% of expected physical exam maneuvers and 32% of expected POCUS skills. At elective conclusion, all participants were effectively able to demonstrate the highest yield physical exam and ultrasound maneuvers. Discussion and Conclusion: An elective designed specifically to integrate POCUS and physical exam modalities improves the ability of resident physicians to utilize both diagnostic modalities.

Abstract
Focused cardiac ultrasound (FoCUS)—a simplified, qualitative version of echocardiography—is a well-established tool in the armamentarium of critical care and emergency medicine. This review explores the extent to which FoCUS could also be used to enhance the preoperative physical examination to better utilise resources and identify those who would benefit most from detailed echocardiography prior to surgery. Among the range of pathologies that FoCUS can screen for, the conditions it provides the most utility in the preoperative setting are left ventricular systolic dysfunction (LVSD) and, in certain circumstances, significant aortic stenosis (AS). Thus, FoCUS could help answer two common preoperative diagnostic questions. First, in a patient with high cardiovascular risk who subjectively reports a good functional status, is there evidence of LVSD? Second, does an asymptomatic patient with a systolic murmur have significant aortic stenosis? Importantly, many cardiac pathologies of relevance to perioperative care fall outside the scope of FoCUS, including regional wall motion abnormalities, diastolic dysfunction, left ventricular outflow obstruction, and pulmonary hypertension. Current evidence suggests that after structured training in FoCUS and performance of 20–30 supervised examinations, clinicians can achieve competence in basic cardiac ultrasound image acquisition. However, it is not known precisely how many training exams are necessary to achieve competence in FoCUS image interpretation. Given the short history of FoCUS use in preoperative evaluation, further research is needed to determine what additional questions FoCUS is suited to answer in the pre-operative setting.

Abstract
The use of bedside ultrasound over the past few decades has created a new wave of options for visualizing pathological processes allowing for faster and better detection of disease. We aimed to evaluate the reliability of focused cardiac ultrasound (FCU) performed by first-year internal medicine residents at a community hospital after a short period of training. They received a two-hour lecture and initially performed a supervised FCU followed by ten unsupervised/independent FCUs each. The four parameters that were assessed were left systolic ventricular function, right systolic ventricular function, presence of pericardial effusion, and presence of IVC dilation. Interpretation and analysis of ultrasound images were then carried out by both the residents and an attending physician with expertise in FCU analysis and interpretation. Cohen's Kappa values were obtained comparing the results found by the interns versus the attending. Our findings indicate that more training is required for reliable analysis of FCU by first-year medical residents. Our results also emphasize the need to carefully evaluate the medical residents' FCU skills after the training.

Abstract
BACKGROUND Incorporating focused cardiac ultrasonography (FoCUS) into clinical examination could improve the diagnostic yield of bedside patient evaluation. PURPOSE To compare the accuracy of FoCUS-assisted clinical assessment versus clinical assessment alone for diagnosing left ventricular dysfunction or valvular disease in adults having cardiovascular evaluation. DATA SOURCES English-language searches of MEDLINE, Embase, and Web of Science from 1 January 1990 to 23 May 2019 and review of reference citations. STUDY SELECTION Eligible studies were done in patients having cardiovascular evaluation; compared FoCUS-assisted clinical assessment versus clinical assessment alone for the diagnosis of left ventricular systolic dysfunction, aortic or mitral valve disease, or pericardial effusion; and used transthoracic echocardiography as the reference standard. DATA EXTRACTION Three study investigators independently abstracted data and assessed study quality. DATA SYNTHESIS Nine studies were included in the meta-analysis. The sensitivity of clinical assessment for diagnosing left ventricular dysfunction (left ventricular ejection fraction <50%) was 43% (95% CI, 33% to 54%), whereas that of FoCUS-assisted examination was 84% (CI, 74% to 91%). The specificity of clinical assessment was 81% (CI, 65% to 90%), and that of FoCUS-assisted examination was 89% (CI, 85% to 91%). The sensitivities of clinical assessment and FoCUS-assisted examination for diagnosing aortic or mitral valve disease (of at least moderate severity) were 46% (CI, 35% to 58%) and 71% (CI, 63% to 79%), respectively. Both the clinical assessment and the FoCUS-assisted examination had a specificity of 94% (CI, 91% to 96%). LIMITATION Evidence was scant, persons doing ultrasonography had variable skill levels, and most studies had unclear or high risk of bias. CONCLUSION Clinical examination assisted by FoCUS has greater sensitivity, but not greater specificity, than clinical assessment alone for identifying left ventricular dysfunction and aortic or mitral valve disease; FoCUS-assisted examination may help rule out cardiovascular pathology in some patients, but it may not be sufficient for definitive confirmation of cardiovascular disease suspected on physical examination. PRIMARY FUNDING SOURCE None. (PROSPERO: CRD42019124318).

Abstract
The availability of miniaturized ultrasound machines has changed our approach to many cardiovascular diseases. Handheld ultrasound imaging can be performed at the bedside, it is easy to use, and the information provided, although limited, is of unquestionable importance for a quick diagnosis that leads to early treatment. They have unique characteristics: Low cost, wide availability, safety, accuracy, and can be used in different clinical scenarios and by operators with different backgrounds. Image acquisition and interpretation is rapid and provides, in each situation, useful information for diagnosis, prognosis, and clinical and therapeutic management. This review focuses on the use of handheld ultrasound devices, describes differences with other equipment, their limitations, and the numerous advantages derived from their use.

Abstract
BACKGROUND Early identification of patients with reduced left ventricular ejection fraction (LVEF) could facilitate the care of patients with suspected heart failure (HF). We examined if (1) focused cardiac ultrasound (FCU) performed with a hand-held device (Vscan 1.2) could identify patients with LVEF < 50%, and (2) the distribution of HF types among patients with suspected HF seen at primary care clinics. METHODS FCU performed by general practitioners (GPs)/GP registrars after a training programme comprising 20 supervised FCU examinations were compared with the corresponding results from conventional cardiac ultrasound by specialists. The agreement between groups of estimated LVEF < 50%, after visual assessment of global left ventricular function, was compared. Types of HF were determined according to the outcomes from the reference examinations and serum levels of natriuretic peptides (NT-proBNP). RESULTS One hundred patients were examined by FCU that was performed by 1-4 independent examiners as well as by the reference method, contributing to 140 examinations (false positive rate, 19.0%; false negative rate, 52.6%; sensitivity, 47.4% [95% confidence interval [CI]: 27.3-68.3]; specificity, 81.0% [95% CI: 73.1-87.0]; Cohen's κ measure for agreement = 0.22 [95% CI: 0.03-0.40]). Among patients with false negative examinations, 1/7 had HF with LVEF < 40%, while the others had HF with LVEF 40-49% or did not meet the full criteria for HF. In patients with NT-proBNP > 125 ng/L and fulfilling the criteria for HF (68/94), HF with preserved LVEF (≥50%) predominated, followed by mid-range (40-49%) or reduced LVEF (< 40%) HF types (53.2, 11.7 and 7.4%, respectively). CONCLUSIONS There was poor agreement between expert examiners using standard ultrasound equipment and non-experts using a handheld ultrasound device to identify patients with reduced LVEF. Asides from possible shortcomings of the training programme, the poor performance of non-experts could be explained by their limited experience in identifying left ventricular dysfunction because of the low percentage of patients with HF and reduced ejection fraction seen in the primary care setting. TRIAL REGISTRATION The study was registered at ClinicalTrials.gov (NCT02939157). Registered 19 October 2016.

Abstract
BACKGROUND Three-dimensional echocardiography (3D-Echo) performed by novice health care staff to measure left ventricular ejection fraction (LVEF) could allow cost-effective screening and monitoring for left ventricular systolic dysfunction (LVSD) prior to the development of heart failure. The aim of this study was to determine feasibility and accuracy of cardiac nurses (after completing focussed training) independently acquiring 3D-Echo images, and measuring LVEF using semi-automated software when compared to an echosonographer. METHODS One echosonographer and three cardiac nurses acquired 3D-Echo images on 73 patients (62 ± 16 years, 62% male) with good image quality, and subsequently measured LVEF using a semi-automated algorithm. RESULTS Overall feasibility was 89% with the three nurses successfully acquiring 3D-Echo images suitable for LVEF assessment in 65 of the 73 patients. High accuracy (r = 0.82; p < 0.0001) with minimal bias (+0.1, -10.6 to +10.8 limits of agreement; p = 0.91) was observed comparing the nurses to the echosonographer for measuring LVEF. Individual nurses demonstrated high feasibility (86%-92%), accuracy (r = 0.83-0.87; all p < 0.0001) and intra-observer reproducibility (r = 0.96-0.97; all p < 0.0001), with good inter-observer consistency in accuracy compared to the echosonographer (one-way analysis of variance p = 0.559). CONCLUSIONS We have demonstrated that, following a focussed training protocol, it was feasible for cardiac nurses to acquire 3D-Echo images of sufficient image quality to allow measurement of LVEF using a semi-automated algorithm, with comparable accuracy and intra-observer variability to an expert echosonographer. This could potentially allow the broader application of echocardiography to screen for LVSD in high-risk cohorts.

Abstract
Whole body ultrasound can be used to improve the speed and accuracy of evaluation of an increasing number of organ systems in the critically ill. Cardiac and abdominal ultrasound can be used to identify the mechanisms and etiology of hemodynamic instability. In hypoxemia or hypercarbia, lung ultrasound can rapidly identify the etiology of the condition with an accuracy that is equivalent to that of computed tomography. For encephalopathy, ocular ultrasound and transcranial Doppler can identify elevated intracranial pressure and midline shift. Renal and bladder ultrasound can identify the mechanisms and etiology of renal failure. Ultrasound can also improve the accuracy and safety of percutaneous procedures and should be currently used routinely for central vein catheterization and percutaneous tracheostomy.

Abstract
Point-of-care ultrasonography (POCUS) has the potential to transform healthcare delivery through its diagnostic expediency. Trainee competency with POCUS is now mandated for emergency medicine through the Accreditation Council for Graduate Medical Education (ACGME), and its use is expanding into other medical specialties, including internal medicine. However, a key question remains: how does one define "competency" with this emerging technology? As our trainees become more acquainted with POCUS, it is vital to develop validated methodology for defining and measuring competency amongst inexperienced users. As a framework, the assessment of competency should include evaluations that assess the acquisition and application of POCUS-related knowledge, demonstration of technical skill (e.g., proper probe selection, positioning, and image optimization), and effective integration into routine clinical practice. These assessments can be performed across a variety of settings, including web-based applications, simulators, standardized patients, and real clinical encounters. Several validated assessments regarding POCUS competency have recently been developed, including the Rapid Assessment of Competency in Echocardiography (RACE) or the Assessment of Competency in Thoracic Sonography (ACTS). However, these assessments focus mainly on technical skill and do not expand upon other areas of this framework, which represents a growing need. In this review, we explore the different methodologies for evaluating competency with POCUS as well as discuss current progress in the field of measuring trainee knowledge and technical skill.

Abstract
Focused cardiac ultrasonography is performed by clinicians at the bedside and is used in time-sensitive scenarios to evaluate a patient's cardiovascular status when comprehensive echocardiography is not immediately available. This simplified cardiac ultrasonography is often performed by noncardiologists using small, portable devices to augment the physical examination, triage patients, and direct management in both critical care and outpatient settings. However, as the use of focused cardiac ultrasonography continues to expand, careful consideration is required regarding training, scope of practice, impact on patient outcomes, and medicolegal implications. In this review, we examine some of the challenges with rapid uptake of this technique and explore the benefits and potential risk of focused cardiac ultrasonography. We propose possible mechanisms for cross-specialty collaboration, quality improvement, and oversight.

Abstract
Introduction Hand-held imaging devices are widely used in clinical practice and are a useful tool. There is no published review examining the diagnostic parameters achieved with these devices in clinical practice. Methods We searched three online medical literature databases (PubMed, EMBASE and MEDLINE) for all literature published up until January 2018. We selected studies that (1) were conducted in the adult population; (2) used a truly hand-held device; (3) featured sensitivities and/or specificities on the use of the hand-held scanner. We extracted and summarised the diagnostic metrics from the literature. Results Twenty-seven articles were excluded from the initial 56 relevant articles, as the device featured was not truly hand-held. Ultimately a total of 25 studies were analysed. Sixteen studies were carried out by experienced users, seven by users with little previous experience and two studies by nurses. High diagnostic parameters were achieved by all three groups when scanning cardiac pathology and intra-abdominal structures. Training of non-expert users varied, taking a mean of 21.6 h. These hand-held devices can change diagnoses at the bedside and be used as gate-keepers to formal echocardiography. Individual studies show them to be cost-effective. Conclusion Hand-held echocardiography is a useful tool in the hands of experts and novices alike. Studies conducted are highly heterogeneous making it difficult to pool data for the diagnostic metrics. Further studies with rigorous methodology are needed to evaluate the true diagnostic potential in the hands of non-experts and in the community as well as to validate training protocols.
