Evaluating the impact of structured POCUS training during internal medicine clerkship and residency training

Background: Point of Care Ultrasound (POCUS) is a vital tool in rheumatology for detecting pathologies like osteophytes and joint effusion. Its integration into rheumatology electives during internal medicine clerkship and residency is limited, despite its emphasis in pre-clinical years. Methods: In this QIRB-approved, single-center, prospective study (2022–2023), third- and fourth-year medical students and internal medicine residents in a two-week rheumatology elective voluntarily completed online surveys. These surveys assessed their confidence using POCUS in rheumatology, using a 5-point Likert scale. Results: A survey of 25 residents and 10 medical students found that 84% of residents and 90% of students rated POCUS training as valuable or very valuable. Both groups felt more confident identifying knee joint effusion (average scores: 3.5 for students, 2.6 for residents) compared to other ultrasound techniques and pathologies. Confidence was lower in hip ultrasounds (2.20 for students, 1.68 for residents) and chondrocalcinosis identification (2.20 for students, 1.76 for residents). Among participants, 28% of residents and 70% of students had prior informal POCUS training. Previous training significantly increased comfort levels, with average scores of 2.86 for students and 2.30 for residents, compared to 2.69 and 1.91 for those without prior training (P-values: <0.001). Conclusion: Prior experience significantly enhances confidence and comfort, reinforcing the need for early, comprehensive, and targeted POCUS training in medical curricula to address proficiency gaps.

Using Point of Care Ultrasound (POCUS) to Assess Gastrostomy Balloon Placement

BACKGROUND: Fluoroscopy is the gold-standard for evaluation of gastrostomy tube (GT) placement, though it is costly and resource intensive. Point of Care Ultrasound (POCUS) has potential as a low-risk alternative to confirm GT placement. OBJECTIVE: To determine the diagnostic accuracy of POCUS for identification of correct gastrostomy balloon placement as compared to fluoroscopy. METHODS: This was a prospective convenience sample of children presenting to interventional radiology for routine GT or gastrojejunal (GJ) tube exchange. Prior to exchange, POCUS operators scanned and interpreted ultrasound images for GT placement, followed by fluoroscopy. A blinded radiologist interpreted fluoroscopic studies. Diagnostic test characteristics, concordance with 95% confidence intervals, and interrater agreement (Cohen's Kappa) between POCUS and fluoroscopy were calculated. RESULTS: Four (3%) of 118 evaluated GT balloons were displaced. Compared to fluoroscopy, novice POCUS assessment of GT/GJ balloon placement had a sensitivity of 86% (79-92%), specificity of 25% (1-81%), PPV of 97% (92-99%), NPV of 6% (1-30%), proportion agreement of 85%, kappa 0.04. Expert POCUS interpretation exhibited sensitivity of 91% (89.5%, 100%), proportion agreement of 89%, kappa 0.08. pH testing had the highest sensitivity of 93% (85%, 97%), proportion of agreement (92%) and kappa (0.20). CONCLUSIONS: POCUS demonstrated a high sensitivity for GT/GJ balloon placement, with low interrater agreement with fluoroscopy. POCUS may not add additional clinical benefit in routine evaluation of gastrostomy tubes over current standards of care. However, POCUS may serve as a useful screening test in settings where fluoroscopy is unavailable or pH is unobtainable.

How to perform Point of Care Ultrasound at resuscitation and when it is useful.

Point of Care Ultrasound (POCUS) can be useful as a tool before, during and after the performance of cardiopulmonary resuscitation (CPR). Before or after resuscitation it can help with monitoring unstable hemodynamics, has the potential to identify reversible causes if patient deteriorates. During resuscitation POCUS can help detect potentially treatable causes of the cardiac arrest. Performance of POCUS while resuscitation requires experienced sonologists and a good team structure to embed the examination in advanced cardiovascular life support (ACLS) algorithms. This article gives an overview and tips about how to detect potential reversible causes of patient deterioration in all three phases of CPR. We describe some special situations in which resuscitation could take place. Further we give a comment about sonographic education of physicians and nonacademic medical staf.

A Multi-step Integrative Workflow Implementation to Improve Documentation of Point of Care Ultrasound in Medical Intensive Care Unit.

Point of care ultrasound (POCUS) provides quick bedside assessment for diagnosing and managing life-threatening conditions in critical care medicine. There has been increasing interest in developing infrastructure to archive images, record clinical interpretation, assess quality, and recoup revenue for POCUS. We present a simple workflow by systems integration of electronic medical record, ultrasound machines, picture archiving, and communication system to facilitate POCUS documentation and billing. We recorded a trend on the number of POCUS performed before and after introduction of the structured integration. We observed and recorded a linear increase over time post-intervention. Our innovative and integrated POCUS workflow is an effective way to document and bill POCUS.

Critical Care Ultrasound in Shock: A Comprehensive Review of Ultrasound Protocol for Hemodynamic Assessment in the Intensive Care Unit.

Shock is a life-threatening condition that requires prompt recognition and treatment to prevent organ failure. In the intensive care unit, shock is a common presentation, and its management is challenging. Critical care ultrasound has emerged as a reliable and reproducible tool in diagnosing and classifying shock. This comprehensive review proposes an ultrasound-based protocol for the hemodynamic assessment of shock to guide its management in the ICU. The protocol classifies shock as either low or high cardiac index and differentiates obstructive, hypovolemic, cardiogenic, and distributive etiologies. In distributive shock, the protocol proposes a hemodynamic-based approach that considers the presence of dynamic obstruction, fluid responsiveness, fluid tolerance, and ventriculo-arterial coupling. The protocol gives value to quantitative measures based on critical care ultrasound to guide hemodynamic management. Using critical care ultrasound for a comprehensive hemodynamic assessment can help clinicians diagnose the etiology of shock and define the appropriate treatment while monitoring the response. The protocol's use in the ICU can facilitate prompt recognition, diagnosis, and management of shock, ultimately improving patient outcomes.

Let the Ultrasound Games Begin: Developing Knowledge and Clinical Skills With Gamification.

Point of Care Ultrasonography (POCUS) is customary practice in the clinical setting. Formal training ensures competent skills using POCUS but is lacking. Preparing nurse practitioners in POCUS with gamification is an innovative educational tool. The Attention, Relevance, Confidence, and Satisfaction (ARCS) model was used to implement POCUS. Learners participated in a bracket-style elimination tournament. Learners (N = 109) in the adult-gerontology acute care nurse practitioner track participated. Eighty-eight Bachelor of Science in Nursing (BSN) to Master of Science in Nursing and 21 BSN to Doctor of Nursing Practice learners. Extremely satisfied with the experience were 72.36%, 67.11% were somewhat comfortable, 10.53% were extremely comfortable, and 11.84% were somewhat uncomfortable using POCUS. Gamification for POCUS training is a practical tool to develop knowledge and comfort using ultrasound. Adult learners retain information in various modalities and gamification offers them a multimodal learning opportunity that increases competency. [J Nurs Educ. 2024;63(X):XXX-XXX.].

2226 Assessing quantitative sonographic changes in the muscle mass of geriatric patients hospitalised using point of care ultrasound

Abstract Introduction One of the most important consequences of hospitalisation in older patients is sarcopenia. This study aims to determine the impact of hospitalisation on the muscle mass, functional status, nutritional status, and short-term clinical outcomes. Methods A prospective study of patients admitted to an Acute Geriatric Ward between 1st November and 30th December 2022. Muscle ultrasound, utilising Point of Care Ultrasound (POCUS) at bedside, was employed to estimate rectus femoris muscle thickness (MT), area (Ar), pennation angle (PA), and fascicle length (FL) at the time of hospital admission, 3 days post-admission, and at hospital discharge. Results 30 patients included, with a median age of 84 years (SD 72–93), 63.3% male, and 70% Clinical Frailty Scale score ≥ 4. Barthel Index and Functional Ambulation Category revealed median values of 72.33 and 3.87 respectively. Global Deterioration Scale median was 2.47. Mini Nutritional Assessment Short-Form (MNA) and total serum protein showed median values of 7.40 and 6.35 respectively. The median length of hospital stay was 5.79 days, with inpatient mortality rate of 10% and 53.3% incidence of delirium. Ultrasound showed a decrease in PA by 36.31%, Ar by 34.30%, and MT by 24.50%, and increase in FL by 10.47%. Sarcopenia classification at admission and discharge revealed an increase in mean index from 5.04 to 7.74. Conclusions In our cohort of patients admitted to an acute geriatric unit, POCUS identified real-time decreases in MT, Ar, and PA at the muscular level before these manifested as functional changes. It demonstrated an inverse relationship between frailty and muscle morphology as living with frailty associated further decreases in muscle mass at discharge. The study also established a direct relationship between MNA, muscle thickness, PA, and fascicles length at discharge. POCUS assessment of muscle mass could indirectly predict outcomes and guide decisions to address muscle mass abnormalities.

Point of Care Ultrasound Guided Management of Lateral Ankle Sprains: A Case Series.

Lateral ankle sprain (LAS) is a common injury with incidence rates reported at 7.2 per 1000 person-years. Physical examination strategies provide limited information to guide rehabilitation that can maximize clinical outcomes. Early and accurate diagnostic information using ultrasound imaging enables individualized care and the ability to monitor healing along with its response to activity and rehabilitation. The purpose of this study was to describe and observe the outcomes associated with Point of Care Ultrasound (POCUS) guided early management of acute and sub-acute lateral ankle sprains. Case series. Individuals with a LAS within the prior 28 days underwent a clinical evaluation to include a POCUS exam to assess ligamentous integrity. Objective and POCUS findings were integrated to classify each LAS into one of four categories. Each grade of ankle sprain corresponded to levels of bracing for the protection of injured structures with each patient receiving physical therapy care based on rehabilitation guidelines. Participants completed the Foot and Ankle Ability Measure (FAAM) activities of daily living and Sports subscale, the Foot and Ankle Outcome Score (FAOS), Patient Reported Outcomes Measurement Information Systems Global Health, Tampa Scale of Kinesiophobia (TSK-11), Cumberland Ankle Instability Tool (CAIT), and the Numeric Pain Rating Scale as well as the Ankle Lunge Test and Figure 8 measurements at baseline, 4 weeks, 8 weeks and 12 weeks post enrollment. The FAAM Sport subscale, all FAOS subscales, and the TSK-11 were also collected at 24 weeks while the CAIT was collected at baseline and 24 weeks. Fourteen participants were enrolled with 11 participants completing all data collection. FAAM Sport scores significantly improved at 4, 8, 12 and 24 weeks. All components of the FAOS significantly increased except for Sport scores at four weeks and Quality of Life scores at four and eight weeks. POCUS guided early management and ligamentous protection of LASs resulted in significant short and long-term improvement in function and return to sporting activity. This case series highlights the feasibility of using ultrasound imaging to assess the severity of ligamentous injury and align bracing strategies for ligamentous protection. The observations from this case series suggest that functional bracing strategies focused on ligamentous protection to promote healing and reduce re-injury rates does not delay improvement in functional outcomes. Level IV, Case Series.

Artificial Intelligence (AI) Applications for Point of Care Ultrasound (POCUS) in Low-Resource Settings: A Scoping Review.

Advancements in artificial intelligence (AI) for point-of-care ultrasound (POCUS) have ushered in new possibilities for medical diagnostics in low-resource settings. This review explores the current landscape of AI applications in POCUS across these environments, analyzing studies sourced from three databases-SCOPUS, PUBMED, and Google Scholars. Initially, 1196 records were identified, of which 1167 articles were excluded after a two-stage screening, leaving 29 unique studies for review. The majority of studies focused on deep learning algorithms to facilitate POCUS operations and interpretation in resource-constrained settings. Various types of low-resource settings were targeted, with a significant emphasis on low- and middle-income countries (LMICs), rural/remote areas, and emergency contexts. Notable limitations identified include challenges in generalizability, dataset availability, regional disparities in research, patient compliance, and ethical considerations. Additionally, the lack of standardization in POCUS devices, protocols, and algorithms emerged as a significant barrier to AI implementation. The diversity of POCUS AI applications in different domains (e.g., lung, hip, heart, etc.) illustrates the challenges of having to tailor to the specific needs of each application. By separating out the analysis by application area, researchers will better understand the distinct impacts and limitations of AI, aligning research and development efforts with the unique characteristics of each clinical condition. Despite these challenges, POCUS AI systems show promise in bridging gaps in healthcare delivery by aiding clinicians in low-resource settings. Future research endeavors should prioritize addressing the gaps identified in this review to enhance the feasibility and effectiveness of POCUS AI applications to improve healthcare outcomes in resource-constrained environments.

Point of Care Ultrasound (POCUS) in the Management of Heart Failure: A Narrative Review.

Assessing for volume overload is a key component of both short and long-term management of heart failure patients. Physical examination findings are neither sensitive nor specific for detecting congestion, and subclinical congestion may not be evident at the time of examination. Point of care ultrasound (POCUS) is an efficient and non-invasive way to assess heart failure patients for volume overload. The aim of our narrative review is to summarize how each of the following ultrasound modalities can be used to assess for congestion in the heart failure population: 2D and Doppler echocardiography, lung ultrasound, inferior vena cava ultrasound, internal jugular vein ultrasound, and venous excess grading. While each of these modalities has their limitations, their use in the acute and outpatient space offers the potential to reduce heart failure readmissions and mortality.

Subglottic dilatation in extremely preterm infants on prolonged mechanical ventilation

BackgroundAirway injuries are reported among preterm infants with bronchopulmonary dysplasia. We hypothesized that prolonged ventilation in preterm infants is associated with subglottic dilatation that can be reliably evaluated by point of care ultrasonography (POCUS). MethodsAll preterm infants (<29-weeks) admitted to the neonatal ICU at the Advent-Health from January-2020 to June-2022 were eligible if they required invasive ventilation for ≤7 days in the first 28 days of life (control) or remained intubated for ≥28 days (prolonged ventilation). Sonography was performed by one technician and all images were reviewed by the pediatric radiologist. The trachea size was measured 3 times by randomly selecting three images. The first 20 scans were also independently reported by a different pediatric radiologist. Intra and inter-observer variability was estimated. Mean trachea size and weight at the time of imaging were compared. ResultsOut of 417 eligible infants; 11 died before 28 days and 163 required ventilation for 8–27 days. Consent missed for 80 infants during COVID-19 pandemic. We enrolled 23 and 28 infants in the control & prolonged ventilation groups, respectively. Inter and intra-observer correlations were 0.83 and 0.97 respectively. Infants in the control group had higher gestation and birth weight. Infants on prolonged ventilation were at higher risk for infections, BPD, longer hospital stay and significant subglottic dilation (4.51 ± 0.04 vs 4.17 ± 0.02 mm, p < 0.01) despite smaller body weight at the time of imaging (884 ± 102 vs 1059 ± 123g, p < 0.01). ConclusionExtremely preterm infants on prolonged ventilation are at risk for sub-glottic dilatation that can be reliably measured by POCUS.

Factors influencing the use of Point Of Care Ultrasound (POCUS) on adult patients by Accident and Emergency Department (A&amp;amp;E) Doctors in Tertiary Care Hospitals in Colombo District, Sri Lanka; a Descriptive Cross-Sectional Study

Introduction:Point of care ultrasound (PoCUS) is an essential component of A&amp;E setting all over the world. It is used for diagnosis and assisting bedside procedures. Usage of PoCUS has been shown to improve quality of patient care. There are no formal studies in Sri Lankan A&amp;E setting to assess level of its usage and the barriers of using it. This study aimed to assess these aspects among ED doctors in three tertiary care hospitals in Colombo district.Methodology:This descriptive study was conducted by self-administered questionnaires distributed among 72 ED doctors working in the above setting. Questionnaire consisted of questions related to sociodemographics, types of PoCUS performed, barriers to PoCUS use etc. Ability to perform PoCUS was assessed by Likert grading from 1 to 5 based on operator’s own opinion. Statistical analysis was done using SPSS.Results: All the tertiary care emergency services had access to an ultrasound machine. PoCUS has been used for a wide variety of bedside scans and therapeutic procedures. Majority has been used to detect free fluid in peritoneal cavity (66.6%) and FAST scans (65.3%). Post graduate doctors (PG) were more confident in configuring PoCUS machine for procedures than non PG doctors (82.8% vs 5.4%). Ability to perform PoCUS was associated with post graduate exposure, &gt;1 year of experience using it and doing &gt;300 procedures in last 3 months (p=0.001). Main barriers identified for PoCUS usage were lack of training and lack of quality ultrasound machine.Discussion: Though PoCUS is mainly performed by PG doctors, important scans such as FAST, intra peritoneal free fluid assessment are done by non-PG doctors too. Compared to similar international studies, less number of latter doctors were capable of doing PoCUS in Sri Lanka. Empowering these doctors with PoCUS skills will improve the sustainably of this service in emergency care setup as they work in units for longer duration. A study where candidates’ skills are assessed by a third party would have provided more accurate reflection of PoCUS usage.Conclusion: Embracing updated technology and further improvement and availability of PoCUS training among ED doctors will enhance sustainable emergency patient care in Sri Lanka.

A Study on the Effective Follow-up Care Method After Laser Treatment: Focusing on Skin Health Behavior

Recently, women in their 30s and 40s are paying attention to making their skin appear whiter and cleaner through pigmentation treatments such as laser toning. For the effectiveness of the procedure and rapid recovery, follow-up care after the laser procedure is also necessary. Through this study, we tried to find out the efficacy of skin health behavior according to the care method after the laser procedure. Skin health behavior (daily life habits, dietary habits, sleep habits, and the presence or absence of cosmetic health supplements) was compared and analyzed by dividing the study subjects receiving vitamin care, ultrasound care, and cryo care for women in their 30s and 40s into three groups. A total of 300 questionnaires were surveyed for a week from August 5 to August 11, 2022, using PCs and mobile phones, and a total of 300 copies were collected. As a result of the study, ultrasound and cryo care alternately dominated the post-care process evaluation and skin improvement satisfaction, while vitamin care was continuously at the bottom. On the other hand, in terms of skin health behavior, overall, ultrasound, cryo, and vitamin care groups scored high. Based on the results of this study, it is expected that it will become the cornerstone of clinical data to be used in the future by developing a skin whitening program through personalized skin counseling in the practice of hospitals and clinics.

Pre-hospital ultrasonography screening for biliary disease in remote settings

AbstractScreening ultrasound, including Point of Care Ultrasonography (POCUS), is widely utilized for rapid clinical guidance in diverse healthcare settings. In this case report, a 34-year-old male with recurrent biliary colic symptoms underwent a Basic Emergency Service ultrasound, revealing a 13 mm gallbladder calculus and signs of inflammation, and was promptly referred to the hospital for further evaluation and treatment. Medical specialist confirmation at the hospital underscored the significance of early detection through POCUS. Despite inconclusive laboratory results, the detailed ultrasound assessment provided a comprehensive understanding, emphasizing the tool's value in averting complications. Thus, screening ultrasound played a pivotal role in justifying the hospital referral, showcasing its vital role in healthcare, especially in resource-limited settings. The judicious use of POCUS can lead to superior outcomes, avoiding unnecessary referrals for non-emergent cases.

UNLOADING STRATEGIES IN ADVANCED HEART FAILURE: THE ROLE OF POINT–OF–CARE ULTRASOUND

Abstract Patients with advanced heart failure (HF) exhibit repeated episodes of fluid retention (pulmonary and/or systemic congestion) and/or of reduced cardiac output at rest (peripheral hypoperfusion) requiring hospitalization along with diuretics/inotropic infusion. Pulmonary artery catheter (PAC) provides haemodynamic information to guide the therapy, however PAC is invasive and time consuming. Point of care ultrasonography (POCUS) represents a promising diagnostic tool at the bedside, performed by the physician to assess non invasively volume status, cardiac output and monitor decongestive therapy. Recently, abnormal Doppler flow patterns due to increased right atrial pressure have been described in the hepatic, portal, and intrarenal veins. Thus, the recent venous excess ultrasound score (VExUS) has been used to describe fluid status along with the diameter and collapsibility of the inferior vena cava. Furthermore HF patients show high filling pressures, therefore they often require mechanical or medical unloading. In this regard, point of care ultrasound represents a valid tool to monitor non invasively the filling pressures and the responsiveness to those treatments. Here, we illustrate with several clinical cases where VExUS/POCUS were pivotal in clinical management.

Point of Care Ultrasounds Obtained by Novice Physician Assistant Residents (POCUS ON PAR).

The integration of Point of Care Ultrasound (POCUS) into the care of trauma patients, specifically the E-FAST, has improved the accuracy of initial diagnoses and improved time to surgical intervention in critically ill patients. Physician assistants (PAs) are critically important members of any military trauma resuscitation team and are often team leaders in a pre-hospital setting. They may receive training in ultrasound but there are little data to support their use or evaluate their effectiveness in using POCUS. We designed a study to evaluate the image quality of an E-FAST Exam performed by Emergency Medicine Physician Assistant (EMPA) Fellows and Emergency Medicine (EM) Interns following identical training. Our hypothesis is that image quality obtained by EMPAs will be non-inferior to those images obtained by EM Interns. This is a prospective single-blinded study comparing the image quality of E-FAST exams performed by first year EM interns and first year EMPA fellows. All participants completed standard POCUS training prior to enrollment in the study. A total of 8 EMPAs and 8 EM first year residents completed 10 recorded E-FAST exams to be used as study images. Participants also viewed a 15-question slide show containing images of positive (6) and negative (9) E-FAST exams and recorded their interpretations. Images were reviewed by expert reviewers who were blinded to which images were collected by which group. An image quality score was recorded for each view as well as an overall image quality score. Image quality was rated on a 1 to 5 image quality scale. For overall image quality, the mean score for EMPAs was 3.6 ± 0.5 and for EM residents was 3.2 ± 0.5 with statistical significance favoring better image quality from the EMPAs. The time to completion for the EFAST exam for EMPAs was 4.8 ± 1.3 minutes and for interns it was 3.4 ± 1.4 minutes (P value = 0.02). There was no difference in image interpretation quiz scores between the groups (mean score 92% among interns and 95% among PAs). POCUS is an imaging modality which is very portable and relatively inexpensive which makes it ideal for military medicine. PAs are essential members of military trauma teams, and often run an initial trauma resuscitation. Being able to correctly identify patients who have free fluid early in the course of treatment allows for more correct evacuation criteria to ensure the sickest patients get to care the fastest. Although there are limited data to support POCUS use by non-physicians, our data support a growing body of evidence that it is not the profession or baseline medical education that determines an individual's ability to use and incorporate ultrasound into bedside and clinical practice. Our study shows that with training and experience PAs or other members of the military health care team can use the EFAST to better care for trauma patients.

Wireless handheld ultrasound for internal jugular vein assessment in pediatric patients.

Rapid evolution of ultrasound technology has allowed widespread use of handheld ultrasound devices (HHUDs) for many possible applications. Along with the adult population, the use of HHUDs for Point of Care Ultrasound (POCUS) in pediatric medicine has been increasing over the last few years. However, pediatric-specific literature is still scarce on mobile vascular ultrasound. To evaluate diagnostic capabilities of Vscan Air™ in comparison with high-end ultrasound for the assessment of the internal jugular vein in children and adolescents. 42 Internal Jugular Veins (IJVs) of 21 pediatric patients were scanned by an experienced examiner using a WLAN-supported handheld ultrasound device (Vscan Air™) and high-end cart-based ultrasound (LOGIQ E9) as reference. B-Mode and Color-coded Doppler (CCDS) were performed and compared. Image quality was assessed using a score of 0 to 5 and statistically analyzed. Results were interpreted independently by two readers in consensus. 21 patients (2-17 years; mean 11,00±4,5 years; female n = 11, male n = 10) were examined. The rating score never dropped below 3 for both devices. The median score evaluation of B-Mode and CCDS for the high-end device was 5.00, of Vscan Air™ 5.00 for B-Mode and 4.00 for CCDS. A significant difference was shown between the two devices in the evaluation of CCDS. Vscan Air™ ultrasound device allows sufficient assessability of the IJV in pediatric patients, opening up new possibilities for fast and mobile POCUS of cervical veins and potential guidance of central venous catheter placement.
