Patients' experiences of the use of point-of-care ultrasound in general practice - a cross-sectional study

Point-of-care ultrasound in nephrology: A private practice viewpoint

Point-of-care ultrasound (POCUS) is a limited ultrasound examination performed by the clinician at the bedside, emerging as a complement to physical examination across various medical specialties. In the field of nephrology, its integration has been gradual, primarily limited to guiding procedures like temporary dialysis catheter placement or, in some cases, diagnostic kidney ultrasounds. In reality, the assessment of hemodynamic status at the bedside holds immense value for nephrologists, yet there exists limited awareness among practitioners regarding its implementation. While there is a growing trend towards incorporating multi-organ POCUS training in fellowship programs, private practice nephrologists remain relatively uninformed. This discussion explores the untapped potential of POCUS as a valuable diagnostic tool in everyday nephrology practice, demonstrating its effectiveness in diverse clinical settings, ranging from medical wards to outpatient dialysis units. Additionally, we delve into the challenges hindering its widespread adoption and consider the future trajectory of this innovative approach.

Is it worth trying? A cross-sectional study on the implementation of point-of-care ultrasound in Hungarian primary care

BACKGROUND

Although the number of point-of-care ultrasound devices available in Hungarian primary care practices are increasing due to government funding, their use in day-to-day patient care is limited and unregulated. Our study aimed to evaluate the attitudes and needs of general practitioners (GPs) and patients in Hungary regarding the introduction of bedside ultrasonography in primary care practices.

METHODS

As a part of a cross-sectional study, an anonymous, self-administered questionnaire was distributed to GPs and patients on a social media platform. Data collection was carried out from August 2023 to October 2023. Chi-square test was used to determine the associations between categorical variables.

RESULTS

The survey was completed by 415 GPs (mean age 53.8 ± 11.1 years, 54.9% female, mean 19.5 ± 11.9 years of practice) and 693 patients (mean age 45.5 ± 12.3 years, 95.2% female). There was a statistically significant increase in interest in PoCUS among young and middle-aged GPs (age 28-59; p = 0.02). In addition, this population of GPs was also more likely to undertake training in PoCUS than their older colleagues (p < 0.0001). An inverse relationship was found between the duration of practice and training willingness (p = 0.0011). Even with the government's financial support, only 8.2% of GPs currently use PoCUS in a daily basis, and 59.5% of GPs are unfamiliar with the indications and the ways of using it. Patients would even pay to have the examination done in a primary care setting, even though only 45.9% of patients would pay a GP who is not certified in PoCUS, but the willingness to pay increased to 99.4% for those with formal training (p = 0.024).

CONCLUSION

Our findings indicate a significant interest in adapting PoCUS in primary care from both GPs and patients. Based on the fact that a significant proportion of Hungarian GPs are unaware of PoCUS and its indications, it is particularly important to develop educational frameworks, and practical guidelines for the effective incorporation of PoCUS in Hungary.

Implementation of lung ultrasonography by general practitioners for lower respiratory tract infections: a feasibility study

OBJECTIVE

To evaluate the feasibility of lung ultrasonography (LUS) performed by novice users' general practitioners (GPs) in diagnosing lower respiratory tract infections (LRTIs) in primary health care settings.

DESIGN

A prospective interventional multicenter study (December 2019-March 2020).

SETTINGS AND SUBJECTS

Patients aged >3 months, suspected of having LRTI consulting in three different general practices (GPs) (rural, semirural and urban) in France.

MAIN OUTCOME MEASURES

Feasibility of LUS by GPs was assessed by (1) the proportion of patients where LUS was not performed, (2) technical breakdowns, (3) interpretability of images by GPs, (4) examination duration and (5) patient perception and acceptability.

RESULTS

A total of 151 patients were recruited, and GPs performed LUS for 111 (73.5%) patients (LUS group). In 99.1% (n = 110) of cases, GPs indicated that they were able to interpret images. The median [IQR] exam duration was 4 [3-5] minutes. LRTI was diagnosed in 70.3% and 60% of patients in the LUS and no-LUS groups, respectively (p = .43). After LUS, GPs changed their diagnosis from 'other' to 'LRTI' in six cases (+5.4%, p < .001), prescribed antibiotics for five patients (+4.5%, p = .164) and complementary chest imaging for 10 patients (+9%, p < .001). Patient stress was reported in 1.8% of cases, 81.7% of patients declared that they better understood the diagnosis, and 82% of patients thought that the GP diagnosis was more reliable after LUS.

CONCLUSIONS

LUS by GPs using handheld devices is a feasible diagnostic tool in primary health care for LRTI symptoms, demonstrating both effectiveness and positive patient reception.

Development of the Children's ACuTe UltraSound (CACTUS) point-of-care ultrasound (POCUS)-accredited training in the UK: a descriptive study

Point-of-care ultrasound (POCUS) is an established, evidence-supported tool that can be used in neonatal and paediatric medicine, offering clinicians immediate diagnostic insights, assessment of interventions and improved safety profiles and success rate of various procedures. Its effective use requires an established education programme, governance and standardisation to ensure competence in this skill. While adult clinical practice has established POCUS training protocols, this had not been replicated in paediatrics. This article describes the development and launch of the UK's inaugural accredited paediatric-specific POCUS curriculum and training pathway: the 'Children's ACuTe UltraSound' course, addressing this significant gap in paediatric healthcare education and describing the training delivered and available for paediatricians and allied health professionals working with children.

Point-of-care ultrasound (POCUS): Assessing patient satisfaction and socioemotional benefits in the hospital setting

Point-of-care ultrasound (POCUS) is an imaging modality used to make expedient patient care decisions at bedside. Though its diagnostic utility has been extensively described, POCUS is not yet considered standard of care in inpatient settings. Data from emergency department settings suggest that POCUS may yield socioemotional benefits beyond its diagnostic utility; furthermore, elements of the POCUS experience are known to promote placebo effects. These elements likely contribute to a placebo-like "POCUS positive care effect" (PPCE) with socioemotional benefits for receptive patients. Our objective is to provide the first characterization of the PPCE and its facilitating factors in an inpatient setting. In this novel mixed-methods study, we recruited 30 adult patients admitted to internal medicine floors in an urban academic medical center, recorded observations during their routine POCUS encounters, and administered post-encounter surveys. We conducted complementary quantitative and qualitative analyses to define and assess the magnitude of the PPCE. We also aimed to identify factors associated with and facilitating receptiveness to the PPCE. The results indicated that POCUS improves patients' satisfaction with their hospital providers and care overall, as well as perceived care efficiency. Mutual engagement, strong therapeutic alliances, and interpreting POCUS images to provide reassurance are most closely associated with this PPCE. Patients who have lower anxiety levels, less severe illness, and received efficient care delivery during their hospitalizations are most receptive to the PPCE. We conclude that diagnostic POCUS has the potential to exert a positive care effect for hospitalized patients. This PPCE is associated with modifiable factors at the patient, provider, and environment levels. Together, our findings lay the groundwork for an optimized "therapeutic POCUS" that yields maximal socioemotional benefits for receptive patients.

Impact of point-of-care ultrasound use on patient referral decisions in rural Kenya: a mixed methods study

BACKGROUND

Point-of-care ultrasound (POCUS) is recognized as a key imaging modality to bridge the diagnostic imaging gap in Low- and Middle-Income Countries (LMICs). POCUS use has been shown to impact patient management decisions including referral for specialist care. This study explored the impact of POCUS use on referral decisions among trained healthcare providers working in primary rural and peri-urban health facilities in Kenya.

METHODS

A concurrent mixed methods approach was used, including a locally developed survey (N = 38) and semi-structured interviews of POCUS trained healthcare providers (N = 12). Data from the survey was descriptively analyzed and interviews were evaluated through the framework matrix method.

RESULTS

Survey results of in-facility access to Xray, Ultrasonography, CT scan and MRI were 49%, 33%, 3% and 0% respectively. Only 54% of the facilities where trainees worked had the capacity to perform cesarean sections, and 38% could perform general surgery. Through a combined inductive and deductive evaluation of interview data, we found that the emerging themes could be organized through the framework of the six domains of healthcare quality as described by the Institute of Medicine: Providers reported that POCUS use allowed them to make referral decisions which were timely, safe, effective, efficient, equitable and patient-centered. Challenges included machine breakdown, poor image quality, practice isolation, lack of institutional support and insufficient feedback on the condition of patients after referral.

CONCLUSION

This study highlighted that in the setting of limited imaging and surgical capacity, POCUS use by trained providers in Kenyan primary health facilities has the potential to improve the patient referral process and to promote key dimensions of healthcare quality. Therefore, there is a need to expand POCUS training programs and to develop context specific POCUS referral algorithms.

Point-of-care ultrasound Usage and accuracy within a Canadian urology division

INTRODUCTION

This research evaluates the utility and precision of point-of-care ultrasound (POCUS) in urology, inspired by recent affirmations of its feasibility and value.1,2 Our study provides valuable insights for urologists about POCUS's practical usage.

METHODS

A prospective study assessed POCUS usage and accuracy in the University of Alberta's Division of Urology using data from April 4, 2022, to April 4, 2023. Data include POCUS indications, findings, and correlation with the final diagnosis/gold standard. Additionally, a qualitative survey was conducted among urologists and residents about POCUS's pros, cons, and barriers to integration.

RESULTS

Thirty-three patients underwent POCUS examinations, mainly for suspected hydronephrosis (27%, n=9). Other indications included urinary retention, testicular mass, torsion, cryptorchidism, renal mass, extended focused assessment with sonography in trauma (eFAST ) exams, nephrostomy tube placement confirmation, and scrotal hematomas. POCUS findings matched the final diagnosis in most cases, showing 86% sensitivity, with an average exam time of 1-5 minutes. POCUS showed potential for suprapubic tube insertions. Residents (60%, n=20) were the most frequent users, followed by staff (33%, n=10), and students (6%, n=2). The surveyed urologists and residents expressed comfort with POCUS but cited time, cost, and practicality as barriers.

CONCLUSIONS

POCUS proves accurate and beneficial in urology, particularly for hydronephrosis. Most findings align with the gold standard, and the average exam time is brief. Barriers include time and cost. Further research is necessary to evaluate cost-effectiveness and POCUS's impact on patient outcomes in routine urologic practice.

A Clinician's Guide to the Implementation of Point-of-Care Ultrasound (POCUS) in the Outpatient Practice

Point-of-care ultrasound (POCUS) is a valuable clinical tool used at the patient bedside to rapidly assess a wide variety of symptoms and problems which would otherwise take hours or even days. Though it has become the standard of care in Emergency Medicine and is becoming so in hospital internal medicine, less uptake has been appreciated in the outpatient setting despite reported interest from clinicians practicing there. A number of common barriers have been cited to explain this gap in use, which usually include access to equipment, mentorship, and time. In this review we present a proposed framework for clinicians who have an interest in implementing POCUS in their outpatient practice which we hope can mitigate some of these barriers and provide a more streamlined pathway to their desired goals.

Seeing through the myths: Practical aspects of diagnostic point-of-care ultrasound in nephrology

Point of care ultrasonography (POCUS) is emerging as an invaluable tool for guiding patient care at the bedside, providing real-time diagnostic information to clinicians. Today, POCUS is recognized as the fifth pillar of bedside clinical examination, alongside inspection, palpation, percussion, and auscultation. In spite of growing interest, the adoption of diagnostic POCUS in nephrology remains limited, and comprehensive training beyond kidney ultrasound is offered in only a few fellowship programs. Moreover, several misconceptions and barriers surround the integration of POCUS into day-to-day nephrology practice. These include myths about its scope, utility, impact on patient outcomes and legal implications. In this minireview, we address some of these issues to encourage wider and proper utilization of POCUS.

Past and Present of Point-of-Care Ultrasound (PoCUS): A Narrative Review

This article aims to conduct a literature review to gain insight into point-of-care ultrasound (PoCUS). PoCUS is a rapid, accurate, non-invasive, and radiation-free imaging modality that can be used in stable and unstable patients. PoCUS can be performed parallel to physical examination, resuscitation, and stabilization; repeated exams in critical patients are essential for improving sensitivity. The review highlights how PoCUS, which was initially used to detect free intraperitoneal fluid in trauma patients, has developed into a life-saving diagnostic tool that could be utilized by treating physicians during various stages of diagnosis, resuscitation, operation, and postoperative critical care when managing sick patients. The review also notes the barriers to the widespread uptake of PoCUS in general internal medicine and the recent commercial availability of "pocket" or handheld probes that have made PoCUS more readily available. This review concludes that adopting a focused binary decision-making approach can maximize PoCUS's value in many clinical settings, including emergency departments, intensive care units, and operation theatres. Overall, the review emphasizes the importance of awareness of common indications, limitations, and strengths of this evolving and promising technology to determine its future trajectory: Providing comprehensive PoCUS training within internal medicine curriculums and supporting trainers to do so.

Evolution and impact of a dedicated ultrasound clinic on clinical rheumatology practice at an academic medical center

BACKGROUND

Rheumatologic ultrasonography (RhUS) has grown in scope and application over the past 20 years. While many studies have shown the benefits of RhUS, few have investigated the efficacy of a dedicated clinic. This study explores the impact of a dedicated ultrasound clinic on patients and rheumatologists at an academic medical center (AMC).

METHODS

We analyzed claims data for patient visits, X-rays (XR), magnetic resonance imaging (MRI), and RhUS from an AMC with an established RhUS clinic, alongside two affiliated community medical practices (CMPs) without RhUS. We also analyzed RhUS clinic records on referral indication, procedures, results, and follow-up treatment changes. Pre- and post-RhUS visit patient surveys and referring physician (RP) surveys assessed experience and impact of the RhUS clinic.

RESULTS

From 2018 to 2021, referrals to the RhUS clinic substantially increased. In parallel, XR and MRI orders changed by -76 % and -43 % respectively, compared with 163 % and -24 % at CMPs. Discordance between RP pre-RhUS assessments and RhUS results were common. Patient surveys showed RhUS led to increased disease understanding and impacted thoughts and decisions about their therapy. RPs found utility in RhUS across a range of indications and were confident with RhUS results.

CONCLUSIONS

These findings suggest a dedicated RhUS clinic can be a valuable resource in clinical rheumatology practice. Implementation of a RhUS clinic at this AMC spurred rapid adoption of RhUS into clinical decision-making with notable benefits for patients and physicians alike. This may serve as a model for implementation of similar clinics at other institutions.

Nephrologist-Led Simulation-Based Focused Cardiac Ultrasound Workshop for Medical Students: Insights and Implications

Background

Point-of-care ultrasonography (POCUS) is being increasingly recognized as an adjunct to physical examination. However, limited availability of trained faculty in specialties other than emergency medicine and lack of universal training standards remain key barriers to its widespread integration into undergraduate and graduate medical curricula. In this study, we sought to explore the effectiveness of a short simulation-based workshop for medical students teaching basic cardiac ultrasound led by a nephrologist.

Methods

Workshops were conducted for 2 different groups of 4th-year medical students with a total of 25 attendees. The workshop consisted of a 1-hour lecture followed by 15 minutes of cardiac anatomy simulation and a 2- to 2.5-hour hands-on session in the simulation laboratory. An anonymous precourse questionnaire comprising 10 questions assessing the interpretation of common grayscale ultrasound findings encountered in patients with undifferentiated hypotension was performed. After the workshop, a postcourse exam and survey were conducted, retesting the same concepts and seeking the students' feedback on the course.

Results

In total, 23 and 20 students answered the pre- and postcourse surveys, respectively. The mean total score on the pretest was 63.8% ± 13.6%, which significantly increased to 91.5% ± 10.5% on the posttest (P < .001). About 90% of the respondents strongly agreed that the cardiac anatomy simulation improved their understanding of the cardiac sonographic anatomy; 75% strongly agreed that the hands-on simulation enhanced their confidence in image acquisition and interpretation; and 70% said they would choose nephrology elective if POCUS training was integrated with it.

Conclusions

A nephrologist-led diagnostic POCUS workshop using simulation techniques is effective in improving the learners' knowledge, understanding of the sonographic cardiac anatomy, and confidence in image acquisition. Integration of POCUS training may increase medical student interest in nephrology elective rotations.

Antenatal ultrasound needs-analysis survey of Australian rural/remote healthcare clinicians: recommendations for improved service quality and access

BACKGROUND

Ultrasound is the primary diagnostic tool in pregnancy, capable of identifying high-risk pregnancies and life-threatening conditions, allowing for appropriate management to prevent maternal and fetal morbidity and mortality. Women and babies from rural and remote Australia and low-resource areas worldwide experience poorer health outcomes and barriers to accessing antenatal care and imaging services. Healthcare clinicians working in these regions face significant challenges practising with limited resources and accessing training opportunities.

OBJECTIVE

To perform an exploratory needs-analysis survey investigating the availability, accessibility and use of antenatal ultrasound in rural Australia, exploring rural clinicians' interest in and access to ultrasound training opportunities.

METHODS

The survey tool for this cross-sectional study was designed and distributed as an anonymous online questionnaire targeting healthcare clinicians (doctors, nurses, midwives, clinic managers, Aboriginal healthcare workers) providing antenatal care in rural regions. Descriptive analysis was applied to quantitative data and thematic analysis was used to explore qualitative components.

RESULTS

A total of 114 valid survey responses were analysed. Overall, 39% (43/111) reported ultrasound was not used when providing antenatal care to patients at their clinic, stating 'Lack of ultrasound equipment (73%,29/40) and inaccessibility of training opportunities (47%,19/40) as the main reasons. For those with ultrasound (61%,68/111), estimating due date (89%,57/64) was the main use, and limited training/skills to operate the equipment (59%,38/64) and inaccessibility/distance of training opportunities (45%,29/64) were the most commonly reported barriers. Clinicians described a lack of childcare options (73%,74/102), long distances to reach ultrasound services (64%,65/102), appointment (59%,60/102) and transport availability/times (46%,47/102) as the main obstacles to patient access. Increased attendance, compliance with care directives, parental bonding and improved lifestyle choices were described by respondents as positive outcomes of antenatal ultrasound use.

CONCLUSIONS

Future efforts to combat inequitable service access must adopt a coordinated approach to meet the needs of pregnant women in low-resource settings. Providing portable ultrasound equipment, training in antenatal Point-of-Care ultrasound (PoCUS) with ongoing support/mentoring and accreditation of health professionals could strengthen rural workforce capacity. This, along with addressing the complex economic, environmental and socio-cultural barriers faced by patients, could improve service access and pregnancy outcomes in rural and remote communities.

Factors affecting point-of-care ultrasound implementation in general practice: a survey in Danish primary care clinics

OBJECTIVE

The implementation of point-of-care ultrasound (POCUS) in general practice varies, but it is unknown what determines this variation. The purpose of this study was to explore (1) the overall proportion of POCUS-users among general practitioners (GPs), (2) the current use of POCUS by GPs, (3) factors related to the implementation of POCUS in general practice and (4) GPs' concerns related to POCUS use in general practice.

DESIGN

An online survey was distributed in June 2019.

SETTING

General practice.

PARTICIPANTS

GPs working in office-based primary care clinics in Denmark.

MAIN OUTCOME MEASURES

The questionnaire was developed using mixed methods and included questions about participants' characteristics, past POCUS training and experience, capability, opportunity and motivation for using POCUS in the primary care setting. Results were summarised using descriptive statistics. Association between GPs' background characteristics and POCUS use was tested using logistics regression.

RESULTS

Responses were analysed from 1216 questionnaires corresponding to 36.4% of all GPs in Denmark. The majority (72.3%) of participants had previous POCUS experience, 14.7% had access to a POCUS device and 11.5% used POCUS. Several factors motivated participants to use POCUS. However, barriers existed such as lack of remuneration and high workload. Additionally, many GPs questioned their ability to scan with sufficient diagnostic accuracy and the impact of POCUS on the consultation. Of non-users, 28.7% believed they would be using POCUS in the future.

CONCLUSION

Although, the majority of GPs had past experience with POCUS and felt motivated to use it, few had implemented POCUS. Several factors influenced the GPs' capability, opportunity and motivation for using POCUS and several concerns were registered by non-users.

Point-of-Care Ultrasound Overview and Curriculum Implementation in Internal Medicine Residency Training Programs in the United States

Point-of-care ultrasonography (POCUS) augments physical examination and expedites diagnostic care and clinical decision-making. The use of POCUS in internal medicine (IM) appears inconsistent despite its commendable benefits. It is not fully incorporated into the IM residency core competency skills or academic curriculum. This narrative literature review explores the benefits of POCUS and evaluates the need for an IM-focused POCUS curriculum. The obstacles and a proposed curriculum are also described.

Barriers and Facilitators to Point-of-Care Ultrasound Use in Rural Australia

This study explores the barriers and facilitators to point-of-care ultrasound (POCUS) use and adoption in rural healthcare since POCUS is a useful resource for rural clinicians to overcome the challenges associated with limited on-site clinical support, such as limited diagnostic imaging services and infrastructure. A qualitative descriptive study was employed, interviews with ten rural clinicians were conducted, and the data were analysed using the Walt and Gilson health policy framework to guide interpretation. Barriers include a lack of standardised training requirements, the cost of the devices and challenges recouping the costs of purchase and training, difficulty with the maintenance of skills, and a lack of an effective method to achieve quality assurance. Coupling POCUS with telemedicine could address the issues of the maintenance of skills and quality assurance to facilitate increased POCUS use, leading to positive patient safety and social and economic implications.

Point of care ultrasonography in onco-nephrology: A stride toward better physical examination

Onco-Nephrology is an emerging subspecialty of Nephrology that focuses on a broad spectrum of renal disorders that can arise in patients with cancer. It encompasses acute kidney injury (AKI), complex fluid, electrolyte, and acid-base disorders, as well as chronic kidney disease caused or exacerbated by cancer and/or its treatment. In many such scenarios including AKI and hyponatremia, objective evaluation of hemodynamics is vital for appropriate management. Point of care ultrasonography (POCUS) is a limited ultrasound exam performed at the bedside and interpreted by the treating physician intended to answer focused clinical questions and guide therapy. Compared to conventional physical examination, POCUS offers substantially higher diagnostic accuracy for various structural and hemodynamic derangements. In this narrative review, we provide an overview of the utility of POCUS enhanced physical examination for the Onconephrologist supported by the current evidence and our experience-based opinion.

Implementation and Evaluation of a Longitudinal Flipped-Classroom Point-of-Care Ultrasound Curriculum at an Internal Medicine Residency Program

BACKGROUND

Point-of-care ultrasound (POCUS) has extensive clinical utility in internal medicine, but formal and uniform curricula in internal medicine are lacking.

OBJECTIVE

To determine the effectiveness of a longitudinal, flipped-classroom, academic half-day curriculum on internal medicine resident confidence, utilization, and changes in clinical management.

METHODS

We implemented an asynchronous, flipped-classroom, academic half-day curriculum from November 2020 to November 2021 and conducted an evaluation with a prospective, before-after cohort study. Curriculum included 4 rotating sessions comprised of 20 to 30 min of image interpretation followed by 1.5 to 2 h of image acquisition. Confidence was rated via Likert scale. Utilization was reported via indicating never, 1 to 2, 3 to 4, 5 to 6, or >6 times per month (recorded as 1-5, respectively). Image interpretation was assessed via a 6-question, multiple-choice video assessment.

RESULTS

Nineteen of 99 potential residents (19%) completed a pre- and post-curriculum evaluation. Residents attended a median of 4 sessions. Confidence improved from 2.47 to 3.53 (P = .002). Utilization did not improve overall (2.11-2.42, P = .22), but utilization of left ventricular function assessment (1.53-2.00, P = .046) and pulmonary assessment (1.53-2.00, P = .039) increased. The percentage of residents that had ever changed their clinical management by POCUS increased from 47% to 84% after implementation of the curriculum. Cardiac, pulmonary/pleural, volume assessment, and abdominal free fluid exams were reported as the most clinically useful.

CONCLUSION

Implementation of a longitudinal, academic half-day curriculum for POCUS resulted in improved confidence, increased POCUS utilization for the cardiac and pulmonary examination, and changes in clinical management based on POCUS.

Ultrasound assessment of SARS-CoV-2 pneumonia: a literature review for the primary care physician

The SARS-CoV-2 pandemic is considered one of the most critical global health emergencies in the last century. The diagnostic approach to the novel coronavirus disease (COVID-19) and its possible complications through a point-of-care-ultrasound (POCUS) evaluation could represent a good solution in the primary care setting. POCUS is a non-invasive technique that can be used outside hospitals to screen COVID-19 patients and their complications safely. Moreover, it offers several applications of diagnostic evaluation not only on lung parenchyma but also to search disease complications, such as the cardiovascular system, even at the patients' home. This narrative review aims to analyse the literature and provide data to primary care physicians engaged in monitoring and treating patients with SARS-CoV-2 infection. Key MessagesPOCUS is an important tool for the diagnostic approach in the primary care setting already before the start of the SARS-CoV-2 pandemic.Portable devices are useful in monitoring the clinical evolution of patients with infection from SARS-CoV-2 at home.The ultrasonographic features can help the general practice physicians to evaluate the presence of lung involvement and to diagnose complications from the SARS-CoV-2 infection involving districts such as the cardiovascular system.

Point-of-care ultrasound: An emerging clinical tool to enhance physical assessment

ABSTRACT

Point-of-care ultrasound (PoCUS) is a cost-effective diagnostic technology that, with training, is accessible, portable, and a convenient diagnostic modality to complement physical assessments. PoCUS is beneficial in that it can reduce the number of imaging tests required, while also mitigating barriers to healthcare for rural and remote communities.

General Practitioners' Perspectives on Appropriate Use of Ultrasonography in Primary Care in Denmark: A Multistage Mixed Methods Study

PURPOSE

Researchers aimed to describe general practitioners' understanding of appropriate ultrasound use, to record actual scanning practices of early adopters in general practice, and to identify differences between attitudes and actual practice via a mixed methods analysis.

METHODS

This study was part of a larger multistage mixed methods research framework exploring the use of ultrasound in general practice in Denmark. We used an exploratory sequential approach in the data collection with initial qualitative findings from an interview study applied to building a quantitative questionnaire utilized in a cohort study. In addition, we merged the qualitative and quantitative data using joint display analysis to compare and contrast the results from the 2 stages of the study.

RESULTS

In the interviews, general practitioners described appropriate ultrasound use as point-of-care examinations with a clear purpose and limited to predefined specific conditions within delimited anatomic areas. They stated that general practitioners should receive formalized ultrasound training and be skilled in the examinations they perform. In the cohort study, general practitioners performed ultrasound examinations of anatomic areas with or without a defined clinical suspicion. Some performed ultrasound examinations for which they had no previous training or skills.

CONCLUSIONS

We found a difference between the ideas about the appropriate uses for ultrasound in general practice and the actual use by early adopters in clinical practice. Our findings suggest a need for evidence-based guidelines to support general practitioners in choosing which examinations to perform and strategies for developing and maintaining scanning competency.

Racial Disparity in Pediatric Radiography for Forearm Fractures

Introduction: The most common pediatric fractures involve the upper extremity. But there is limited study on racial disparity in diagnostic radiography for pediatric fractures. The literature has described the diagnostic accuracy of alternative diagnostic modalities with promising evidence of its ability to mitigate health inequity in primary care. Our objective was to understand if racial disparity exists in radiography for pediatric fractures.

Methods: In this four-year retrospective cohort study, we analyzed rates of radiographic imaging and abnormal radiograph detection in 4280 pediatric patients (ages 3-18 years) who presented with chief complaints of arm or wrist pain and trauma-related International Classification of Diseases 10th Revision (ICD-10) codes. We compared White children to all other races and stratified by emergency departments (ED) vs all other primary care ambulatory service lines. 

Results: Non-White patients had lower imaging rate differences and lower odds receiving imaging in both ambulatory settings (0.65915, P = 0.0162; -5.4%, P = 0.0143) and in EDs (0.7732, P = 0.0369; -4.7%, P = 0.0368). Additionally, non-Whites in the ED had lower rates and lower odds of abnormal radiographs (-7.3%, P = 0.0084; 0.6794, P = 0.0089). 

Conclusion: Non-White patients seen in emergency and ambulatory settings had lower imaging rates for traumatic arm and wrist pain compared to White patients, indicating a healthcare disparity in pediatric imaging. Higher-level studies investigating the effect of social determinants of health, more detailed patient data, and provider bias on facture care equity are needed to understand underlying reasons for observed differences.

A Blueprint for an Integrated Point-of-Care Ultrasound Curriculum for Nephrology Trainees

Point-of-care ultrasonography (POCUS) is a limited ultrasound study performed by the clinician at the bedside as a component or an adjunct to physical examination. POCUS has multiple applications in nephrology practice, including evaluation of obstructive uropathy, objective assessment of volume status, arteriovenous access assessment, and procedural guidance. However, unlike specialties such as emergency medicine, POCUS training is not yet integrated into most nephrology fellowship curricula, and the sonographic applications taught vary widely among fellowship programs. In this article, we have used our institutional experience to provide a roadmap or blueprint for nephrology programs looking to create a POCUS program. We provide an overview of the curriculum, including the basic organization, applications taught, online resources, milestone development, and quality assessment. We also discuss the nuances of POCUS workflow and perspectives on billing for these limited studies. In addition, we share the evaluation forms and sample documentation we use in our program. Future support, in the form of endorsed nephrology society guidelines, is needed before POCUS training is universally incorporated across nephrology fellowship programs.
