ABSTRACT
BACKGROUND AND OBJECTIVES: Severe pneumonia is the leading cause of death among young children worldwide, disproportionately impacting children who lack access to advanced diagnostic imaging. Here our objectives were to develop and test the accuracy of an artificial intelligence algorithm for detecting features of pulmonary consolidation on point-of-care lung ultrasounds among hospitalized children. METHODS: This was a prospective, multicenter center study conducted at academic Emergency Department and Pediatric inpatient or intensive care units between 2018-2020. Pediatric participants from 18 months to 17 years old with suspicion of lower respiratory tract infection were enrolled. Bedside lung ultrasounds were performed using a Philips handheld Lumify C5-2 transducer and standardized protocol to collect video loops from twelve lung zones, and lung features at both the video and frame levels annotated. Data from both affected and unaffected lung fields were split at the participant level into training, tuning, and holdout sets used to train, tune hyperparameters, and test an algorithm for detection of consolidation features. Data collected from adults with lower respiratory tract disease were added to enrich the training set. Algorithm performance at the video level to detect consolidation on lung ultrasound was determined using reference standard diagnosis of positive or negative pneumonia derived from clinical data. RESULTS: Data from 107 pediatric participants yielded 117 unique exams and contributed 604 positive and 589 negative videos for consolidation that were utilized for the algorithm development process. Overall accuracy for the model for identification and localization of consolidation was 88.5%, with sensitivity 88%, specificity 89%, positive predictive value 89%, and negative predictive value 87%. CONCLUSIONS: Our algorithm demonstrated high accuracy for identification of consolidation features on pediatric chest ultrasound in children with pneumonia. Automated diagnostic support on an ultraportable point-of-care device has important implications for global health, particularly in austere settings.

IMPORTANCE: Sleep disorders are associated with a range of health conditions, with poor sleep often further exacerbating individuals' health, well-being, and ability to participate in daily occupations. Weighted blankets offer a potentially simple nonpharmacological sleep intervention option. OBJECTIVE: To summarize available literature on instrumentation and outcomes associated with overnight use of weighted blankets for therapeutic purpose. EVIDENCE REVIEW: A scoping review following the PRISMA review guidelines was conducted. Sources included MEDLINE, Cochrane Library, CINAHL, PsycINFO, Scopus, Embase, and Google. Included studies reported on overnight use of weighted blankets. Critical appraisal of studies was conducted with standardized tools. FINDINGS: Eighteen studies met the inclusion criteria. Positive outcomes were reported for adults, including improved sleep, reduction in medication use, and improved mood. Sleep outcomes were mixed for children and adolescents but included improved occupational performance. Methodological quality of included studies regarding effectiveness was variable. Ten studies included details of the intervention, whereas only one study reported on implementation. No specific guidelines for use were included. CONCLUSIONS AND RELEVANCE: Weighted blankets are used as a sleep intervention for individuals across the life span experiencing a range of health conditions. Currently, there is more evidence of effectiveness with adults, although parents are favorable regarding weighted blanket use for children. Implementation and recommendation of weighted blankets are typically led by occupational therapists, with knowledge of the intervention facilitating use. This review provides information to inform occupational therapists' clinical decision-making and continued implementation of weighted blankets for individuals with sleep problems. Plain-Language Summary: This scoping review summarizes what is known about the use of weighted blankets as a sleep intervention for people of all ages. There is more evidence for overnight use of weighted blankets for adults, with improvements reported in sleep, mood, medication use, and pain. Although there is little evidence of improvement in sleep for children, some children show improvement in everyday functioning, and parents report positive outcomes from overnight use of weighted blankets. These findings suggest that occupational therapists should consider offering or recommending weighted blankets as a sleep intervention option for people of all ages, alongside consideration of individuals' preferences. Development of practice guidelines that incorporate current research findings is urgently needed to support occupational therapists' use of weighted blankets.

Introduction: Gardens and outdoor spaces are an important part of institutional environments for people with dementia. However, evidence regarding the benefits these spaces have for people with dementia is still limited. This paper presents the evaluation of the redevelopment of an inaccessible outdoor space into a therapeutic garden on a high dependency psychogeriatric unit in an acute hospital. Method: A Mixed methods evaluation was undertaken. An interrupted time series analysis investigated the impact of the garden on falls and challenging behaviours of patients using routinely collected data. Perspectives of the redeveloped garden were captured through (a) a staff survey and (b) semi-structured interviews with families of patients. Results: Rates of falls and challenging behaviours dropped at the time of the garden opening but showed increasing rates each month both before and after the garden opened. Most staff believed that the garden provided benefits for patients however limited staff time and concerns over patient safety were barriers to use. Families identified four main themes related to garden use including: (1) being outside (2) occupation and identity, (3) being stimulating, and (4) barriers and facilitators. Conclusion: The garden was regarded positively by families and staff however, there were barriers that prevented it from being better utilised. Staff concerns over risk were not reflected in falls and challenging behaviour outcomes. Further research into how barriers to garden use may be overcome is justified.

OBJECTIVE: The aim of this study was to validate an adult-derived clinical decision rule for ultrasound identification of methicillin-resistant Staphylococcus aureus (MRSA) skin abscesses in a pediatric cohort. METHODS: We conducted a retrospective study of skin and soft tissue infections in patients <21 years presenting to the emergency department who had radiology performed ultrasounds completed and wound cultures obtained. Ultrasound scans were reviewed for edge definition, volume, and shape by 2 pediatric emergency physicians with expertise in point-of-care ultrasound, with approximately 25% of scans reviewed by both experts to evaluate interrater reliability. A third, blinded expert weighed in for discrepancies before analysis. Test performance characteristics were calculated for the clinical decision rule in children. RESULTS: Two hundred nine patients were enrolled, with mean age of 9.8 (±6.7) years; 87 (42%) were male. Sixty-nine (33%) patients had a wound culture positive for MRSA. The clinical decision rule had a sensitivity of 86% (95% confidence interval [CI], 75%-93%), specificity of 32% (95% CI, 25%-41%), positive predictive value of 38% (95% CI, 35%-42%), negative predictive value of 82% (95% CI, 71%-89%), positive likelihood ratio of 1.26 (95% CI, 1.08-1.46), negative likelihood ratio of 0.45 (95% CI, 0.24-0.84), and an odds ratio of 2.8 (95% CI, 1.31-5.97). CONCLUSIONS: This clinical decision rule for ultrasound identification of MRSA abscesses had moderately high sensitivity and negative predictive value in pediatric patients, with similar sensitivity compared with the original adult validation group. Ultrasound may help identify MRSA abscesses, allowing for improved antibiotic choices and outcomes for children with MRSA abscesses.

INTRODUCTION: Access to outdoor space is widely recommended for people with dementia. However, there is limited information on the occupations of people with dementia within these spaces. We sought to review the research literature to identify the occupations of people with dementia in outdoor spaces in residential aged care and/or hospitals and report on features that support occupational participation as well as the benefits of occupational participation in these spaces. METHODS: Scoping review. We searched electronic databases involving health, design, and horticulture literature. Studies were included if they involved people with dementia and considered occupations within gardens or garden-like spaces of hospitals, subacute rehabilitation facilities, or residential aged care. RESULTS: We identified 19 articles meeting the review criteria. Outdoor spaces for people with dementia varied in design and supported a range of occupations with the most common being social occupations, gardening, and physical activities. Quantitative studies suggested that benefits of outdoor occupations for people with dementia were improvements in activity participation, social connection, mood, agitation, light exposure, and sleep. Qualitative studies supported these findings and identified additional perceived benefits such as engagement, maintaining identity, health, and reduced levels of distress. Benefits were also reported for families and staff. CONCLUSIONS: Current literature shows that many occupations can be done outside and that these are beneficial for people with dementia. Despite the wide range of benefits, multiple studies reported that outdoor spaces remain under-utilised. More work is required to design spaces for occupational engagement, support access to outdoor spaces, and promote occupational participation.

OBJECTIVES: Lung ultrasound (LUS) may help determine illness severity in children with acute lower respiratory tract infections (LRTI) but limited pediatric studies exist. Our objective was to determine the association between LUS findings and illness severity in children with LRTI. METHODS: We conducted a prospective study of patients <20 years with LRTI. Trained investigators performed standardized LUS examinations of 12 regions. Blinded sonologists reviewed examinations for individual pathologic features and also calculated a Quantified Lung Ultrasound Score (QLUS). We defined focal severity as QLUS of ≥2 in ≥1 region, and diffuse severity as QLUS of ≥1 in ≥3 regions. The primary outcome was the Respiratory component of the Pediatric Early Warning Score (RPEWS), a 14-item scale measuring respiratory illness severity. Secondary outcomes included hospital admission, length of stay, supplemental oxygen, and antibiotic use. RESULTS: We enrolled 85 patients with LRTIs, 46 (54%) whom were hospitalized (5.4% intensive care). Median RPEWS was 1 (interquartile range 2). Neither individual features on ultrasound nor total QLUS were associated with RPEWS, hospitalization, length of stay, or oxygen use. Mean RPEWS was similar for participants regardless of focal (1.46 versus 1.26, P = .57) or diffuse (1.47 versus 1.21, P = .47) severity findings, but those with focal or diffuse severity, or isolated consolidation, had greater antibiotic administration (P < .001). CONCLUSIONS: In children with LRTI, neither individual features nor QLUS were associated with illness severity. Antibiotics were more likely in patients with either focal or diffuse severity or presence of consolidation on ultrasound.

ABSTRACT: Amyand hernia is a rare type of inguinal hernia defined by the presence of the appendix in the inguinal hernia sac. Clinical diagnosis of Amyand hernia can be challenging because this diagnosis is typically made intraoperatively, often as an incidental finding. Preoperative diagnosis by computed tomography and radiology ultrasound has previously been reported; however, there exists no reports of the diagnosis being made by point-of-care ultrasound. We present a case of Amyand hernia visible on point-of-care ultrasound performed by a pediatric emergency medicine physician.

BACKGROUND AND OBJECTIVES: Measuring pediatric emergency medicine (PEM) fellow competency in point-of-care ultrasound (POCUS) is important for ensuring adequate training and performance. Assessment may include direct observation, image review, quality assessment, and written examination. The purpose of this study was to develop a pediatric POCUS question bank that could subsequently be used as a POCUS assessment for graduating PEM fellows. METHODS: We organized a 10-person question writing group (QWG). Eight hold expertise in POCUS and two hold expertise in medical education. Members of the QWG created questions within four domains: interpretation/diagnosis (50% of questions), anatomy (30%), physics (10%), and pitfalls (10%). POCUS faculty ascertained content validity and the medical education faculty revised questions for syntax and readability. In 2016, we recruited 31 pediatric POCUS experts. The majority were members of the P2 Network, an international group of experts and leaders in PEM POCUS, to participate in three iterative rounds of a modified Delphi process to review, revise, and establish consensus on the question bank. RESULTS: Thirty-one pediatric POCUS experts participated in the three rounds of the modified Delphi process and evaluated 437 questions developed by the expert panel. Forty-nine percent (n = 216) of the questions were accepted in round 1, 30% (n = 130) in round 2, and 11% (n = 47) in the final round. The final question bank included 393 questions covering 17 pediatric POCUS applications. CONCLUSION: We developed a 393-question bank to aid in the assessment of PEM POCUS competency. Future work includes piloting the questions with PEM fellows to evaluate the response process and implementing the assessment tool to establish a minimum passing score.
ABSTRACT
OBJECTIVES: Multisystem inflammatory syndrome in children (MIS-C) associated with coronavirus disease 2019 is a novel pediatric condition with significant morbidity and mortality. The primary objective of this investigation was to describe the point-of-care ultrasound (POCUS) findings in patients evaluated in the emergency department (ED) who were diagnosed with MIS-C. METHODS: A retrospective cross-sectional study was conducted including patients <21-years-old who had POCUS performed for clinical care in a pediatric ED and were diagnosed with MIS-C. Point-of-care ultrasound studies were performed by pediatric emergency medicine attending physicians or fellows. Data abstracted by chart review included patient demographics, clinical history, physical examination findings, diagnostic test results, the time POCUS studies and echocardiograms were performed, therapies administered, and clinical course after admission. RESULTS: For the 24 patients included, 17 focused cardiac ultrasound, 9 lung POCUS, 7 pediatric modified rapid ultrasound for shock and hypotension, 1 focused assessment with sonography for trauma, 1 POCUS for suspected appendicitis, and 1 ocular POCUS were performed by 13 physicians. Point-of-care ultrasound identified impaired cardiac contractility in 5 patients, large intraperitoneal free fluid with inflamed bowel in 1 patient, and increased optic nerve sheath diameters with elevation of the optic discs in 1 patient. Trace or small pericardial effusions, pleural effusions, and intraperitoneal free fluid were seen in 3 patients, 6 patients, and 4 patients, respectively. CONCLUSIONS: This study demonstrates the spectrum of POCUS findings in MIS-C. Prospective studies are needed to help delineate the utility of incorporating POCUS into an ED management pathway for patients with suspected MIS-C.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) present with diagnostic challenges because COVID-19 can cause varied end-organ failures that mimic respiratory distress of pulmonary origin. Early identification of concurrent complications can significantly alter patient management and course. Point-of-care ultrasound (POCUS) can be particularly useful in helping to differentiate concomitant complications with COVID-19. While lung POCUS findings related to COVID-19 have been published, little guidance exists on how ultrasound can be incorporated into a more comprehensive evaluation of patients under investigation for COVID-19. OBJECTIVES: We devised a pathway called COVUS that incorporates POCUS into the initial evaluation of patients under investigation for COVID-19 to guide diagnosis and management. DISCUSSION: The pathway was derived based on a review of literature, consensus from the ultrasound faculty, as well as feedback from the entire faculty group at one academic institution with high volumes of patients with COVID-19. The scanning protocol uses a cardiac-first (rather than lung-first) approach to identify potential concomitant organ failure that may immediately alter management. CONCLUSIONS: COVUS aims to maximize identification of the most immediately life-threatening complications while minimizing time at bedside and provider risk of exposure to COVID-19.

Lung point-of-care ultrasound (POCUS) has been shown to be useful for identifying pulmonary pathology in adult patients with coronavirus disease 2019 (COVID-19). However, pediatric literature for POCUS in COVID-19 is limited. The objective of this case series was to describe lung POCUS findings in pediatric patients with COVID-19. Three patients with COVID-19 who had lung POCUS performed in a pediatric emergency department were included. Point-of-care ultrasound revealed bilateral abnormalities in all patients, including pleural line irregularities, scattered and coalescing B-lines, consolidations, and pleural effusions. Additional pediatric studies are necessary to gain a broader understanding of COVID-19's sonographic appearance in this age group and to determine whether POCUS may be helpful to facilitate diagnosis and expedite management decisions.

BACKGROUND: Pediatric emergency medicine (PEM) point-of-care ultrasound (POCUS) fellowships exist to provide learners with expertise in ultrasound (US) education, administration, and research oversight. Currently, there are no standardized goals or objectives for these programs, resulting in considerable variability in PEM POCUS fellowship training. METHODS: A modified Delphi survey of PEM and general emergency medicine (EM) POCUS experts in Canada and the United States was conducted to obtain consensus regarding the most important curricular components of a PEM POCUS fellowship training program. Participants were solicited from the P2 Network mailing list and from PEM and EM POCUS fellowship directors listed on the Society of Clinical Ultrasound Fellowships and the Canadian Society of POCUS-EM Fellowships websites. Curricular components considered as part of the survey included US skills, educational skills, administrative skills, and research requirements. Consensus was considered to have been reached when ≥80% of respondents agreed to either include or exclude the component in fellowship training. RESULTS: Round 1 of the survey was sent to 311 participants. A total of 118 (37.9%) completed eligibility for the survey, and 92 (78.0%) met eligibility criteria. Of those, 80 (67.8% of eligible participants) completed the first round of the survey. Round 2 of the survey was sent to those who completed part 1, and 64 (80.0%) completed that round. During Round 1, consensus was achieved for 15 of 75 US applications, seven of seven educational skills, nine of 11 administrative skills, and four of six research requirements. In Round 2 of the survey, consensus was reached on two additional US skills, but no additional administrative skills or research requirements. CONCLUSIONS: With a consensus-building process, the core content for PEM POCUS fellowship training was defined. This can help POCUS educators formulate standardized curricula to create consistent training in POCUS fellowship graduates.
ABSTRACT
BACKGROUND: although nurses often place peripheral intravenous (IV) catheters, little is known about their perceptions regarding use of ultrasound guidance. AIM: the authors aimed to determine paediatric emergency department nurses' attitudes toward ultrasound-guided IV access techniques and assessed practice change after training. METHOD: In a cross-sectional study of nurses, they had didactic and hands-on practice sessions, using three short-axis ultrasound-guided IV access techniques on gel models. Outcomes included likability and ease of learning and performing the techniques. A 3-month follow-up questionnaire assessed attitudes and behavioural changes. RESULTS: 18 nurses were enrolled and 17 analysed. Participants liked all three techniques and thought they were easy to learn and perform. Eighty-two percent of the nurses used at least one technique clinically. The two-person self-guided technique was most preferred (65%) and used 3 months later (65%). CONCLUSIONS: nurses reported generally positive attitudes toward all three ultrasound-guided IV access techniques, but preferred the two-person self-guided technique. Owing to the small sample size, these results cannot be generalised and further research is needed.

The Precision Medicine Initiative spearheaded by the National Institute of Health has pioneered a new model of health care focused on health care delivery that is tailored to an individual. Medical advances have already provided clinicians with the tools to better predict treatment outcomes based on the individual needs of each patient's disease process. Three-dimensional printing allows medical devices and implants to be custom made-to-order. Technological advances in preoperative imaging have augmented the ability for surgeons to plan a specific surgical approach for each patient. In a similar vein, point-of-care ultrasound offers the emergency care provider an opportunity to move beyond protocols and provide precise medical care tailored to the acute needs of each ill or injured emergent patient. In this article, we explore several cutting-edge applications of point-of-care ultrasound that can help providers develop a personalized approach to resuscitation and emergent procedures in pediatrics.

The utility of point-of-care ultrasound is well supported by the medical literature. Consequently, pediatric emergency medicine providers have embraced this technology in everyday practice. Recently, the American Academy of Pediatrics published a policy statement endorsing the use of point-of-care ultrasound by pediatric emergency medicine providers. To date, there is no standard guideline for the practice of point-of-care ultrasound for this specialty. This document serves as an initial step in the detailed "how to" and description of individual point-of-care ultrasound examinations. Pediatric emergency medicine providers should refer to this paper as reference for published research, objectives for learners, and standardized reporting guidelines.
