Point-of-care ultrasound for general practitioners: a systematic needs assessment

Abstract

Objective: The aim of the study was to achieve consensus among a group of ultrasound proficient general practitioners (GPs) from Denmark, Norway, Sweden and Finland on which ultrasound scanning modalities and ultrasound-guided procedures are essential to GPs in their daily work for the purpose of including them in a basic ultrasound curriculum.

Design: The Delphi methodology was used to obtain consensus.

Subjects: Sixty Scandinavian GPs with more than two years of point-of-care ultrasound (POCUS) experience were invited to join the Delphi expert panel.

Main outcome measures: In the first Delphi round each member of the panel was asked to produce a list of scanning modalities and procedures which they found relevant to include in a basic ultrasound curriculum. In Delphi round two, these suggestions were presented to the entire panel who assessed whether they found them essential in their daily work. Items not reaching consensus in round two, were presented to the panel in a third and final round. Items reaching more than 67% agreement were included.

Results: Forty-five GPs were included in the study and 41 GPs completed all rounds. Agreement was obtained on 30 scanning modalities and procedures primarily within the musculoskeletal (8), abdominal (5), obstetric (5) and soft tissue (3) diagnostic areas. Four ultrasound-guided procedures were also agreed upon.

Conclusion: A prioritized list of 30 scanning modalities and procedures was agreed upon by a group of ultrasound proficient GPs. This list could serve as a guideline when planning future POCUS educational activities for GPs.

• Key points

• Point-of-care ultrasound (POCUS) is increasingly being used by general practitioners (GPs), but little is known about which ultrasound applications are most used.

• We performed a systematic needs assessment among a group of ultrasound proficient GPs using the Delphi methodology for the purpose of establishing a basic POCUS curriculum.

• The process resulted in a prioritized list of 30 scanning modalities and ultrasound guided procedures.

• Our study provides the basis for an evidence-based basic POCUS curriculum for GPs.

     

Point-of-care ultrasonography in Norwegian out-of-hours primary health care

Objective: The objective of this study is to determine the extent of ultrasound availability in Norwegian casualty clinics and estimate the prevalence of its use.

Design: A retrospective study based on a national casualty clinic registry and data from reimbursement claims.

Setting: Out-of-hours primary health care in Norway.

Subjects: All Norwegian casualty clinics in 2016 and reimbursement claims from 2008 to 2015.

Main outcome measures: Percent of casualty clinics with ultrasound, types of ultrasound devices and probes, reasons for/against ultrasound access, characteristics of clinics with/without ultrasound, frequency of five ultrasound indications and characteristics of the physicians using/not using ultrasound.

Results: Out of 182 casualty clinics, 41 (23%) reported access to ultrasound. Mobile (49%) and stationary (44%) devices were most frequent. Physician request was the most common cited reason for ultrasound access (66%). Neither population served by the casualty clinic nor distance to hospital showed any clear association with ultrasound access. All of the five ultrasound reimbursement codes showed a substantial increase from 2008 to 2015 with 14.1 ultrasound examinations being performed per 10,000 consultations in 2015. Only 6.5% of physicians performed ultrasound in 2015 and males were significantly more likely to use ultrasound than females (OR 1.85, 95% CI: 1.38–2.47, p?Conclusions: Although the use of ultrasound is increasing in out-of-hours Norwegian primary health care, most casualty clinics do not have access and only a minority of physicians use ultrasound.     

Point-of-care ultrasound versus radiology department pelvic ultrasound on emergency department length of stay

BACKGROUND: The study aimed to compare the time to overall length of stay (LOS) for patients who underwent point-of-care ultrasound (POCUS) versus radiology department ultrasound (RDUS).METHODS: This was a prospective study on a convenience sample of patients who required pelvic ultrasound imaging as part of their emergency department (ED) assessment.RESULTS: We enrolled a total of 194 patients who were on average 32 years-old. Ninety-eight (51%) patients were pregnant (<20 weeks). Time to completion of RDUS was 66 minutes longer than POCUS (95%CI 60-73, P<0.01). Patients randomized to the RDUS arm experienced a 120 minute longer ED length of stay (LOS) (95%CI 66-173, P<0.01)CONCLUSION: In patients who require pelvic ultrasound as part of their diagnostic evaluation, POCUS resulted in a significant decrease in time to ultrasound and ED LOS.     

Point-of-care ultrasound in a pandemic: Practical guidance in COVID-19 units

The coronavirus disease 2019 (COVID-19) pandemic has stretched our healthcare system to the brink, highlighting the importance of efficient resource utilization without compromising healthcare provider safety. While advanced imaging is a great resource for diagnostic purposes, the risk of contamination and infection transmission is high and requires extensive logistical planning for intrahospital patient transport, healthcare provider safety, and post-imaging decontamination. This dilemma has necessitated the transition to more bedside imaging. More so than ever, during the current pandemic, the clinical utility and importance of point-of-care ultrasound (POCUS) cannot be overstressed. It allows for safe and efficient beside procedural guidance and provides front line providers with valuable diagnostic information that can be acted upon in real-time for immediate clinical decision-making. The authors have been routinely using POCUS for the management of COVID-19 patients both in the emergency department and in intensive care units turned into “COVID-units.” In this article, we review the nuances of using POCUS in a pandemic situation and maximizing diagnostic output from this bedside technology. Additionally, we review various methods and diagnostic uses of POCUS which can replace conventional imaging and bridge current literature and common clinical practices in critically ill patients. We discuss practical guidance and pertinent review of the literature for the most relevant procedural and diagnostic guidance of respiratory illness, hemodynamic decompensation, renal failure, and gastrointestinal disorders experienced by many patients admitted to COVID-units.     

Scan the lung: Point-of-care ultrasound of a pulmonary consolidation with loculated pleural effusion

Thoracic ultrasound has become an increasingly valuable tool in the evaluation of critically ill patients in the emergency department (ED). The utility of point-of-care ultrasound (POCUS) to identify suspected pneumothorax, pulmonary edema, pleural effusion and pneumonia has been well established (Pagano et al.; Brogi et al.; Cortellaro et al.; Irwin and Cook [1–4]). The 2014 American College of Emergency Physicians (ACEP) Ultrasound Imaging Compendium included lung and pleural ultrasound with the primary indication of identifying pneumothorax and pleural effusion as part of the core POCUS indications for all emergency physicians [5]. We present a unique case in which a patient presented to the ED in respiratory distress. Portable chest X-ray demonstrated near complete opacification of his right hemithorax. POCUS demonstrated a large right sided loculated pleural effusion with associated septations and surrounding consolidation suggestive of a parapneumonic effusion.     

Point-of-care ultrasound in diagnosis and management of congestive nephropathy

Congestive nephropathy is kidney dysfunction caused by the impact of elevated venous pressures on renal hemodynamics. As a part of cardiorenal syndrome, the diagnosis is usually made based on history and physical examination, with findings such as jugular venous distension, a third heart sound, and vital signs as supporting findings. More recently, however, these once though objective measures have come under scrutiny for their accuracy. At the same time, bedside ultrasound has increased in popularity and is routinely being used by clinicians to take some of the guess work out of making the diagnosis of volume overload and venous congestion. In this mini-review, we will discuss some of the traditional methods used to measure venous congestion, describe the role of point-of-care ultrasound and how it can ameliorate a clinician’s evaluation, and offer a description of venous excess ultrasound score, a relatively novel scoring technique used to objectively quantify congestion. While there is a paucity of published large scale clinical trials evaluating the potential benefit of ultrasonography in venous congestion compared to gold standard invasive measurements, more study is underway to solidify the role of this objective measure in daily clinical practice.     

Morbidity figures from general practice: sex differences in traumatology

Background Trauma prevention starts with to find out the extent of the problem and who it affects. Insight into morbidity figures is therefore necessary. Aim To explore sex differences in traumatology and secondary medical care utilization in primary care related to age and socio‐economic status (SES). Methods Data were obtained from an academic continuous morbidity registration project in the Netherlands in the period from 1996 to 2006, in which 13 000 patients were followed in 10 successive years. Results Sex differences showed a male excess from childhood to 45 years and women showing almost double trauma rates in the elderly. Low SES was associated with the greatest incidence of traumas. The largest sex difference in incidence above 65 years appeared in the high SES with more traumas in women compared with men. From this age on, female morbidity in traumatology outnumbered male morbidity regardless of SES. Considering use of referrals, we found that in the age group 15–45 years men made a greater use of secondary medical care. However, the vastest gender influence in medical care utilization was noticed in the age group over 65 years, outnumbered with women. Conclusion Young men and old women are the most at risk for traumatic health problems: men presenting with traumata of the skull, the tibia and ocular trauma's and women with fractures of the femur, humerus and wrist. For both men and women the greatest incidence is in the low SES. Family physicians can play a pivotal role in prevention to focus on their patients with high risks.     

Prevalence and distribution of psychological diagnoses and related frequency of consultations in Norwegian urban general practice

Objective: To investigate the prevalence and distribution of psychological diagnoses made by general practitioners (GPs) in urban general practice and the related frequency of consultations during 12 consecutive months in Norwegian general practice.Design: A cross-sectional study with data extracted from 16,845 electronic patient records in 35 urban GP practicesSetting: Six GP group practices in Groruddalen, Norway.Subjects: All patients aged 16–65 with a registered contact with a GP during 12 months in 2015.Main outcome measures: Frequency and distribution of psychological diagnoses made by GPs, and the number of patients’ consultations.Results: GPs made a psychological diagnosis in 18.8% of the patients. The main diagnostic categories were depression symptoms or disorder, acute stress reaction, anxiety symptoms or disorder and sleep disorder, accounting for 67.1% of all psychological diagnoses given. The mean number of consultations for all patients was 4.09 (95% CI: 4.03, 4.14). The mean number of consultations for patients with a psychological diagnosis was 6.40 (95% CI: 6.22, 6.58) compared to 3.55 (95% CI 3.50, 3.51) (p<0.01) for patients without such a diagnosis. Seven percent of the diagnostic variation was due to differences among GPs.Conclusions: Psychological diagnoses are frequent in urban general practice, but they are covered using rather few diagnostic categories. Patients with psychological diagnoses had a significantly higher mean number of GP consultations regardless of age and sex.Implications: The knowledge of the burden of psychological health problems in general practice must be strengthened to define evidence-based approaches for detecting, diagnosing and treating mental disorders in the general practice population.

Key Points

• Eighteen percent of patients aged 16–65 in our study of patients in urban general practice received one or more psychological diagnoses in 12 months.
• Depression was the most common diagnosis; followed by acute stress reaction, anxiety and sleep disturbance.
• Patients with psychological diagnoses had a significantly higher mean number of consultations compared to patients without such diagnoses regardless of age and sex.

     

Point-of-care ultrasound for the early diagnosis of emphysematous pyelonephritis: A case report and literature review

BACKGROUNDEmphysematous pyelonephritis (EPN) is a rare but fatal necrotic infection of the kidney, which usually leads to septic shock. Therefore, early diagnosis and optimized therapy are of paramount importance. In the past two decades, point-of-care ultrasound (POCUS) has been widely used in clinical practice, especially in emergency and critical care settings, and helps to rapidly identify the source of infection in sepsis. We report a rare case in which a “falls” sign on POCUS played a pivotal role in the early diagnosis of EPN.CASE SUMMARYA 57-year-old man presented with fever and lumbago for 3 d prior to admission. He went to the emergency room, and the initial POCUS detected gas bubbles in the hepatorenal space showing a hyperechoic focus with dirty shadowing and comet-tail artifacts. This imaging feature was like a mini waterfall. His blood and urine culture demonstrated Escherichia coli bacteremia, and EPN associated with septic shock was diagnosed. The patient did not respond to broad-spectrum antibiotic treatment and a perirenal abscess developed. He subsequently underwent computed tomography-guided percutaneous catheter drainage, and fully recovered. We also review the literature on the sonographic features of POCUS in EPN.CONCLUSIONThis case indicates that a “falls” sign on POCUS facilitates the rapid diagnosis of severe EPN at the bedside.     

Headache in children in Dutch general practice

AIM: To describe the occurrence of headache in general practice, the diagnoses made in general practice, and the management. METHOD: Data from the Dutch national survey of morbidity and interventions in general practice were used. The practice population (103 practices) comprised 63,753 children aged 0-14 years. RESULTS: In 634 episodes, headache was a reason for encounter. The incidence of headache presented to the general practitioner was 40.2 per 1000 person years. More than half of the episodes were related to an infectious disease, among which upper respiratory tract infections predominated. The incidence rate of the diagnosis idiopathic headache was 7.3 episodes per 1000 person years. The incidence increased with age and was higher in girls than in boys. In only 12% of cases of idiopathic headache were special investigations carried out, mostly blood examinations. Medication was prescribed in 27% of all episodes of idiopathic headache. In the absence of an infectious disease, many headache episodes were associated with psychosocial problems. Family problems and school problems were mentioned most often. CONCLUSION: Headache in children as reason for encounter is a common problem in general practice, often associated with an infectious disease. When confronted with a child with idiopathic headache, the general practitioner should be aware of a possible psychosocial component.

Mentoring for nurses in general practice: an Australian study

This paper presents findings from a project conducted to recommend a national framework for mentoring for general practice nurses in Australia. The first phase identified challenges and key issues; the second and third phases (reported here) engaged practice nurses and general medical practitioners in discussion to advance thinking on the topic. Outcomes revolved around seven core areas: role confusion and diversity of practice nursing; lack of a defined career pathway for practice nurses; professional isolation of practice nurses; need for general practitioner support; expectations of mentoring; importance of resourcing and infrastructure; and roles, skills and qualities of mentors. Implications of these for the development of a systemic approach to supporting nurses in general practice are discussed, taking into account the inter-professional context and special working relationship between nurses and doctors. Findings revealed keen support for the idea of mentoring for nurses in general practice and indicate success will depend on appropriate resourcing and infrastructure through national, state and local coordination processes.     

Point of care ultrasound (POCUS) telemedicine project in rural Nicaragua and its impact on patient management

Background

Point of care ultrasound (POCUS) is a useful diagnostic tool in medicine. POCUS provides an easy and reproducible method of diagnosis where conventional radiologic studies are unavailable. Telemedicine is also a great means of communication between educators and students throughout the world.

Hypothesis

Implementing POCUS with didactics and hands-on training, using portable ultrasound devices followed by telecommunication training, will impact the differential diagnosis and patient management in a rural community outside the United States.

Materials and methods

This is an observational prospective study implementing POCUS in Las Salinas, a small village in rural western Nicaragua. Ultrasound was used to confirm a diagnosis based on clinical exam, or uncover a new, previously unknown diagnosis. The primary endpoint was a change in patient management. International sonographic instructors conducted didactic and practical training of local practitioners in POCUS, subsequently followed by remote guidance and telecommunication for 3 months.

Results

A total of 132 patients underwent ultrasound examination. The most common presentation was for a prenatal exam (23.5 %), followed by abdominal pain (17 %). Of the 132 patients, 69 (52 %) were found to have a new diagnosis. Excluding pregnancy, 67 patients of 101 (66 %) were found to have a new diagnosis. A change in management occurred in a total of 64 (48 %) patients, and 62 (61 %) after excluding pregnancy.

Conclusion

Implementing POCUS in rural Nicaragua led to a change in management in about half of the patients examined. With the appropriate training of clinicians, POCUS combined with telemedicine can positively impact patient care.     

Childhood migraine in general practice: clinical features and characteristics

Previous studies have evaluated the clinical features and characteristics of migraine in selected children attending hospital clinics. There have, however, been no community studies on the prevalence and characteristics of migraine in children aged 3-11 years in British general practice. In this study, a total of 1,083 children (from 1,104 registered with a general practice) and their parents were interviewed. Possible migraine sufferers took part in an extended interview that assessed various characteristics of the patients and their attacks. The survey showed that migraine attacks started in infancy, and migrainous children were more likely to have mothers with migraine. Some clinical features were found to be age-dependent. Compared with similar hospital surveys there was a lower frequency of attacks recorded but the prevalence of aura was similar to that found in previous studies.     

Point-of-care ultrasound in the diagnosis of neonatal cerebral sinovenous thrombosis

Cerebral sinovenous thrombosis (CSVT) mostly affects sick neonates in the neonatal intensive care unit (NICU) with predisposing or underlying conditions. The clinical presentation is nonspecific which often leads to a delayed or missed diagnosis. Point-of-care ultrasound (POCUS) use in the NICU is rapidly increasing. One of the main uses of neonatologist-performed POCUS is cranial ultrasound which permits diagnosis and monitoring of neurological disease at the bedside. We present the case of a neonate with a complex clinical situation where cranial POCUS permitted a prompt diagnosis and treatment of severe CSVT by imaging the transverse sinuses through the mastoid fontanelle.     

Determinants related to gender differences in general practice utilization: Danish Diet,Cancer and Health Cohort

Objective: This study aims to describe the determinants related to gender differences in the GP utilization in Danish population aged 50–65 years.

Design: Cohort-based cross-sectional study.

Setting: Danish general practice.

Subjects: Totally, 54,849 participants of the Danish Diet, Cancer and Health cohort (50–65 years).

Main outcome measures: The sum of cohort members’ face-to-face consultations with general practitioner (GP) at the cohort baseline year (1993–1997). We obtained data on GP visits from the Danish National Health Service Register at the cohort baseline (1993–1997), when information on lifestyle (smoking, body mass index (BMI), alcohol use, physical activity), medical conditions (somatic and mental), employment, education, gravidity, and hormone therapy (HT) use was collected by questionnaire.

Results: Women had on average 4.1 and men 2.8 consultations per year. In a crude model, women had 47% higher rate of GP visits than men (incidence rate ratio: 1.47; 95% Confidence Interval: 1.45–1.50), which remained unchanged after adjustment for lifestyle, socio-demographic and medical factors, but attenuated to 18% (1.18; 1.13–1.24) after adjustment for female factors (gravidity and post-menopausal HT. In a fully adjusted model, subjects with hypertension (1.63; 1.59–1.67), mental illness (1.63; 1.61–1.66), diabetes (1.56; 1.47–1.65), angina pectoris (1.28; 1.21–1.34), and unemployed persons (1.19; 1.18–1.21) had highest rates of GP visits.

Conclusions: Gravidity and HT use explain a large proportion, but not all of the gender difference in GP utilization. Medical conditions (somatic and mental) and unemployment are the main determinants of GP utilization in men and women, while lifestyle has minor effect.

• Key points

• Female gender remained a dominant determinant of GP utilization, after adjustment for lifestyle, socio-demography, medical and gender specific factors, with females consulting their GP 18% more often than males.

• Female reproductive factors (use of postmenopausal hormone therapy and gravidity) explained a large proportion of the gender variation in use of GP.

• Strongest determinants for GP use among Danish adults aged 50–65 years were the presence of medical conditions (somatic and mental) and unemployment, while lifestyle factors (e.g., body mass index, alcohol consumption and smoking) had minor effect.
