The effect of focused lung ultrasonography on antibiotic prescribing in patients with acute lower respiratory tract infections in Danish general practice: study protocol for a pragmatic randomized controlled trial (PLUS-FLUS).

BACKGROUND: The use of antibiotics is a key driver of antimicrobial resistance and is considered a major threat to global health. In Denmark, approximately 75% of antibiotic prescriptions are issued in general practice, with acute lower respiratory tract infections (LRTIs) being one of the most common indications. Adults who present to general practice with symptoms of acute LRTI often suffer from self-limiting viral infections. However, some patients have bacterial community-acquired pneumonia (CAP), a potential life-threatening infection, that requires immediate antibiotic treatment. Importantly, no single symptom or specific point-of-care test can be used to discriminate the various diagnoses, and diagnostic uncertainty often leads to (over)use of antibiotics. At present, general practitioners (GPs) lack tools to better identify those patients who will benefit from antibiotic treatment. The primary aim of the PLUS-FLUS trial is to determine whether adults who present with symptoms of an acute LRTI in general practice and who have FLUS performed in addition to usual care are treated less frequently with antibiotics than those who only receive usual care. METHODS: Adults (≥ 18 years) presenting to general practice with acute cough (< 21 days) and at least one other symptom of acute LRTI, where the GP suspects a bacterial CAP, will be invited to participate in this pragmatic randomized controlled trial. All participants will receive usual care. Subsequently, participants will be randomized to either the control group (usual care) or to an additional focused lung ultrasonography performed by the GP (+ FLUS). The primary outcome is the proportion of participants with antibiotics prescribed at the index consultation (day 0). Secondary outcomes include comparisons of the clinical course for participants in groups. DISCUSSION: We will examine whether adults who present with symptoms of acute LRTI in general practice, who have FLUS performed in addition to usual care, have antibiotics prescribed less frequently than those given usual care alone. It is highly important that a possible reduction in antibiotic prescriptions does not compromise patients' recovery or clinical course, which we will assess closely.

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.

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.

Learning strategies of general practitioners striving to achieve point-of-care ultrasound competence: a qualitative study.

BACKGROUND: Point-of-care ultrasonography (POCUS) is increasingly used in general practice despite the lack of official educational programmes or guidelines for general practitioners (GPs). AIM: To explore how GPs have learnt to use POCUS and which barriers they have encountered in their learning process. DESIGN AND SETTING: Qualitative study conducted in office-based general practice in Denmark. METHODS: Semi-structured interviews were conducted with 13 GPs who had implemented POCUS without supporting guidelines or regulations. Analysis was carried out using systematic text condensation. The interview data for this study were collected along with data used in a previous study. RESULTS: The participating GPs described having composed their own ultrasound education following a continuous learning process. Basic POCUS competences were achieved through formalized training sessions at hospital departments or courses. The GPs further developed and expanded their scanning skills through additional courses and continuous self-study practice on patients often while consulting internet sources, textbooks or colleagues. Lack of available ultrasound courses, supervision, and clinical guidelines together with time constraints and financial aspects were mentioned as barriers to their ultrasound training. CONCLUSION: This study showed how GPs had composed their own ultrasound education individually and differently, guided by their own experiences and beliefs about good clinical practice. Formalized ultrasound training was considered a prerequisite for achieving basic ultrasound competences while continuous practice was considered paramount to develop and maintain scanning skills. There were several obstacles to overcome in the learning process including lack of supervision, guidance, and opportunity for practicing skills.Key pointsLittle is known about the educational needs of general practitioners striving to achieve ultrasound competences.General practitioners described using formalized training to achieve basic scanning competences and continuous self-study and practice to further develop their skills.Lack of time, supervision, clinical guidelines and ultrasound courses were considered barriers in the learning process together with financial aspects.

A cost-minimisation analysis of performing point-of-care ultrasonography on patients with vaginal bleeding in early pregnancy in general practice: a decision analytical model.

BACKGROUND: Spotting and light vaginal bleeding are common and usually harmless symptoms in early pregnancy. Still, vaginal bleeding may be the first sign of an abortion and often causes distress to pregnant women and leads to an expectation of an ultrasonography examination of the uterus. As point-of-care ultrasonography (POCUS) is increasingly being integrated into general practice, these patients may be clinically evaluated and managed by general practitioners (GPs). This can potentially reduce referrals of patients from the primary to the secondary healthcare sector resulting in societal cost-savings. The primary purpose of this study was to investigate whether the accessibility of POCUS in general practice for patients with vaginal bleeding in early pregnancy is cost-saving compared to usual practice where GPs do not have access to POCUS. A secondary purpose of this study was to estimate a remuneration for GPs performing POCUS on these patients in general practice. METHODS: A cost-minimisation analysis was based on a decision tree model reflecting the two alternatives: general practice with and without GPs having access to POCUS. The robustness of the model results was investigated using probabilistic sensitivity analysis and the following deterministic sensitivity analyses: one-way analyses for the model input parameters and a scenario analysis with a change from a societal to a healthcare sector perspective. An expected remuneration reflecting the add-on cost of Danish GPs performing POCUS was estimated based on the related costs: cost of an ultrasonography scanner, GP's time consumption, ultrasonography training, and utensils per scanning. RESULTS: The difference in average cost between the two alternatives from a societal perspective was estimated to be €110, in favour of general practice with GPs using POCUS. The deterministic sensitivity analyses demonstrated robustness of the results to plausible changes in the input parameters. The expected remuneration for performing POCUS in this specific setting was estimated to be €32 per examination. CONCLUSION: Having GPs perform POCUS on patients with vaginal bleeding in early pregnancy is cost-saving compared to usual practice. The results should be taken with caution as this study was based on early modelling with uncertainties associated with the input parameters in the model.

Involving practice nurse and other assistant clinical staff members in the management of low back pain: A qualitative interview study from Danish general practice.

OBJECTIVES: Involving practice nurse and other assistant clinical staff members in providing information and education to patients with low back pain at follow-up appointments may release more time and improve care in general practice. However, this requires a shift in the division of tasks, and general practitioners' barriers and facilitators for this are currently unknown. The objectives were to explore general practitioners' experiences and perceptions of including assistant clinical staff members in the management of low back pain. METHODS: This is a semi-structured interview study in Danish general practice. General practitioners with a variation in demographics and experience with task-delegation to clinical staff were recruited for in-depth interviews. We used a phenomenological approach to guide the data collection and the analysis in order to gain insight into the subjective experiences of the general practitioners and to understand the phenomenon of 'delegating tasks to practice staff' from the perspective of the general practitioners' lifeworld. Analysis was conducted using an inductive descriptive method. The sample size was guided by information power. RESULTS: We conducted five interviews with general practitioners. All general practitioners had experience with task delegation, but there was a variation in which tasks the general practitioners delegated and to which types of clinical staff members. The following themes were derived from the analysis: general practice organisation, delegating to clinical staff members, doctor-patient relationship, exercise instruction, clinical pathway for patients and external support. CONCLUSION: General practitioners consider patients with low back pain to be a heterogeneous group with a variety of treatment needs and a patient group without any predetermined content or frequency of consultations; this can be a barrier for delegating these patients to clinical staff members.

Danish GPs' Experiences When Managing Patients Presenting to General Practice with Symptoms of Acute Lower Respiratory Tract Infections: A Qualitative Study.

One of the most common indications for antibiotic prescribing in general practice is acute lower respiratory tract infections (LRTI). This study aimed to explore general practitioners' (GPs') considerations and experiences when managing patients with symptoms of an acute LRTI. Individual semi-structured interviews were conducted with seven GPs in the North Denmark Region from January to March 2020. Data were analysed by means of systematic text condensation. The analysis revealed four themes: (1) practicalities of assessing patients with LRTI, (2) assessment of the patient, (3) treatment decisions, and (4) patient expectations. The GPs described having developed individual diagnostic strategies and routines when managing patients with symptoms of an acute LRTI. However, a general assessment of the patient was essential to all the GPs and the diagnosis was seldom based on a single symptom or finding. Most GPs described having great faith in abnormal lung auscultation. The use of C-reactive protein testing served several purposes, such as deciding on the severity of the infection, prescribing antibiotics or not, and as a communicative tool. Diagnostic uncertainty is a driver of antibiotic use and clinical practice might benefit from the development of clinical prediction rules for diagnosing pneumonia.

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

BACKGROUND: The use of point-of-care ultrasonography (POCUS) performed by general practitioners (GPs) in primary care settings is increasing. Previous studies have focused on GP-reported outcomes and little is known about patients' perspectives on the use of POCUS technology within the general practice consultation. The purpose of this study was to examine patients' experiences with POCUS in general practice within the areas where GPs have indicated that POCUS affected aspects of the consultation. METHODS: A questionnaire was developed using a mixed methods sequential design. Analytical themes from interviews with GPs were converted into items in a questionnaire by the research team. The questionnaire was then further developed in several rounds of pilot tests involving both patients and GPs. The final questionnaire was used in a cohort study conducted in 18 Danish office-based general practice clinics from January 2018 to August 2018. All patients examined with POCUS were asked to complete the questionnaire on tablets immediately after their consultation. RESULTS: Out of 691 patients examined, 564 (81.6%) questionnaires were available for analysis. The patients reported that they were well informed about the purpose (98%) and the results (97%) of the POCUS examination; however, 29% reported that they were not informed about the difference between POCUS and an imaging-specialist's ultrasound examination. Almost all patients (99%) reported that POCUS was integrated naturally into the consultation, and 45% reported that POCUS improved the doctor-patient relationship. The majority of patients felt that they had been more thoroughly examined (92%) and taken more seriously (58%) when POCUS was part of the consultation. They felt POCUS gave them a better understanding of their health problem (82%), made them feel more secure (86%) and increased their trust in the physician's assessment (65%). Moreover, the patients reported that POCUS use improved the level of service (95%) they experienced and the quality of care (94%) in general practice. CONCLUSION: We found that an examination including POCUS in general practice was a positive experience overall for the majority of patients. Future research should further explore reasons for patient confidence in POCUS and whether or not the reassuring value of POCUS is valid.

Education of general practitioners in the use of point-of-care ultrasonography: a systematic review.

OBJECTIVE: To systematically review and synthesize the published literature regarding the education of general practitioners (GPs) and GPs in training (GPTs) in the use of ultrasonography. DESIGN: This systematic review was prospectively registered in PROSPERO, conducted according to the Cochrane recommendations. We combined studies identified in a previous systematic review with studies from an updated literature search using the same search string. We searched the following databases: MEDLINE via Pubmed, EMBASE via OVID, Cinahl via Ebsco, Web of Science and Cochrane Register of Controlled Trials using the words 'ultrasonography' and 'general practice'. Two reviewers independently screened articles, extracted data and assessed the quality of included papers according to the Down and Black quality assessment tool. Disagreements were resolved by involving a third reviewer. RESULTS: Thirty-three papers were included. Ultrasound training was described to include both theoretical and practical training sessions. Theoretical training was achieved through introductory e-learning and/or didactic lectures. Practical training included focussed hands-on training sessions, while some papers described additional longitudinal practical training through proctored scans during clinical work or through self-study practice with continuous feedback on recorded scans. CONCLUSION: There was a large variation in ultrasound training programs for GPs and GPTs, with an overall emphasis on focussed practical training. Few studies included a longitudinal learning process in the training program. However, diagnostic accuracy seemed to improve with hours of practical training, and studies including continuous feedback on scans conducted during clinical patient encounters showed superior results.

Point-of-care ultrasonography is increasingly used by general practitioners (GPs) working in primary care as a diagnostic tool providing earlier and more precise diagnoses. However, ultrasonography is a user-dependent technology and obtaining competence requires both training and practice. Today, there is no consensus about which ultrasound training GPs should have before they start scanning patients in their clinics.

Introducing point-of-care ultrasound in Danish general practice-elucidating the use through a medical audit.

BACKGROUND: Point-of-care ultrasonography (PoCUS) is increasingly used across the medical field. PoCUS is also being implemented in general practice despite a lack of clinical guidelines and training programs for general practitioners (GPs). OBJECTIVES: This study aimed to elucidate the employment of PoCUS by Danish GPs following a short training program. METHODS: Thirty GPs were enrolled in a short ultrasound training program and taught how to perform 22 selected scanning modalities. In the following 3 months, the GPs registered all performed PoCUS examinations according to the Audit Project Odense method. After 5 months, the GPs were invited to participate in an evaluation seminar, where questionnaires were distributed. RESULTS: During the registration period, 1598 patients were examined with PoCUS. A total of 1948 scanning modalities were registered, including 207 examinations outside the taught curriculum. The majority of the ultrasound examinations were performed within 10 minutes (89%), most were considered to be conclusive (87%) and/or to increase diagnostic certainty (67%), whereas one in four examinations entailed a change in patient management. Most GPs attending the evaluation seminar continued to use PoCUS and found the scanning modalities included in the course curriculum relevant in their daily work. CONCLUSION: The GPs found several indications for performing PoCUS following the attendance of a 2-day basic training program. The majority of examinations were registered to be conclusive and/or increase diagnostic certainty. However, few GPs used PoCUS on a daily basis and not all examinations were registered to have an impact on patient care.

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

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 pointsPoint-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.

Danish general practitioners have found their own way of using point-of-care ultrasonography in primary care: a qualitative study.

BACKGROUND: General practitioners increasingly use point-of-care ultrasonography despite a lack of evidence-based guidelines for their appropriate use in primary care. Little is known about the integration of ultrasonography in general practice consultations and the impact of its use on patient care. The purpose of this study was to explore general practitioners' experiences of using ultrasonography in the primary care setting. METHODS: Adopting an explorative phenomenological approach, we performed semi-structured interviews with general practitioners who used ultrasonography in their daily work. Thirteen general practitioners were recruited stepwise, aiming for maximum variation in background characteristics. Interviews were conducted at the general practitioner's own clinic. Transcription and systematic text condensation analysis began immediately after conducting each interview. RESULTS: The general practitioners described using ultrasonography for both selected focused examinations and for explorative examinations. The two types of examinations were described differently for each of the following emerging themes: motivation for using ultrasonography, ultrasonography as part of the consultation, selection of an ultrasound catalogue, and consequences of the general practitioner's ultrasound examination. The general practitioners had chosen and integrated their own individual ultrasound catalogue of focused examinations as a natural part of their consultations. The focused examinations were used to answer simple clinical questions and they had a significant impact on the patients' diagnoses, clinical pathways and treatments. The general practitioners considered their own catalogue of focused examinations as their comfort zone. However, they also performed explorative ultrasound examinations outside their catalogue. These scans were performed to train, gain or maintain ultrasound competences or as explorative examinations driven by curiosity. The explorative ultrasound examinations rarely had an impact on patient care. CONCLUSIONS: This study describes how general practitioners found their own way of using ultrasonography in general practice and selected a personal catalogue of ultrasound examinations that was applicable, relevant and meaningful for their daily clinical routines. This study may serve to inform implementation strategies in general practice by offering insights into central aspects that drive general practitioners' behaviours.

Point-of-Care Ultrasound in General Practice: A Systematic Review.

PURPOSE: Ultrasound examinations are currently being implemented in general practice. This study aimed to systematically review the literature on the training in and use of point-of-care ultrasound (POCUS) by general practitioners. METHODS: We followed the Cochrane guidelines for conduct and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting. We searched the databases MEDLINE (via PubMed), EMBASE, CINAHL, Web of Science, and Cochrane Central Register of Controlled Trials using the key words ultrasonography and general practice in combination and using thesaurus terms. Two reviewers independently screened articles for inclusion, extracted data, and assessed the quality of included studies using an established checklist. RESULTS: We included in our review a total of 51 full-text articles. POCUS was applied for a variety of purposes, with the majority of scans focused on abdominal and obstetric indications. The length of training programs varied from 2 to 320 hours. Competence in some types of focused ultrasound scans could be attained with only few hours of training. Focused POCUS scans were reported to have a higher diagnostic accuracy and be associated with less harm than more comprehensive scans or screening scans. The included studies were of a low quality, however, mainly because of issues with design and reporting. CONCLUSIONS: POCUS has the potential to be an important tool for the general practitioner and may possibly reduce health care costs. Future research should aim to assess the quality of ultrasound scans in broader groups of general practitioners, further explore how these clinicians should be trained, and evaluate the clinical course of patients who undergo scanning by general practitioners.

Recovery of renal function succeeding stem cell transplant: a case of C3 Glomerulonephiritis secondary to monoclonal gammopathy.

Membranoproliferative glomerulonephritis (MPGN) and C3 glomerulonephritis (C3 GN) can be secondary to monoclonal gammopathy and multiple myeloma. MPGN Type 1 is caused by activation of the classical pathway by immune complex formation, and C3 GN results from abnormalities in the alternative pathway of complement. In previously reported cases of MPGN and C3 GN secondary to monoclonal gammopathy/multiple myeloma, renal outcome has been poor. Here, we present the first patient, to our knowledge, who showed full renal recovery and normalization of the complement system after chemotherapy and stem cell transplantation.
