Visión general y comparación de la presencia de médicos en los servicios de emergencias médicas prehospitalarios en Europa / Physician utilization in prehospital emergency medical services in Europe: an overview and comparison

Antecedentes: Los sistemas nacionales y regionales de prestación de atención médica a las emergencias pueden diferir mucho entre sí. Se buscó dilucidar la presencia de médicos en la atención prehospitalaria y su implantación en los diferentes países europeos. Métodos: Se analizaron los datos de 32 países europeos recogidos mediante la revisión de artículos publicados y a través de cuestionarios enviados a los autores de artículos científicos pertinentes, funcionarios del ministerio de sanidad (o equivalente), representantes de sociedades nacionales de medicina de urgencias o expertos reconocidos en medicina de urgencias. Resultados: Treinta de los 32 países europeos investigados (94%) disponen de médicos en los servicios de emergencias prehospitalarios. En 17 de 32 (53%), los médicos generalistas también participan en la atención a las emergencias prehospitalarias. Los modelos de los sistemas de emergencias médicas (SEM) se describieron como francoalemanes en 27 países (84%), híbridos en 17 (53%) o angloamericanos en 14 (44%). En 17 países (53%), coexistían diferentes modelos. Utilizando una nueva forma de clasificación por niveles, basada en la población media y el área atendida por el SEM prehospitalario, se pudieron diferenciar claramente los diferentes modelos existentes. Conclusiones: Se observan notables diferencias en los diseños de los SEM y en la presencia de los médicos entre las diferentes áreas geográficas, países y regiones de Europa. Coexisten varios modelos (francoalemán, híbrido y angloamericano), algunos simultáneamente, en los diferentes países. (AU)

Background: National and regional systems for emergency medical care provision may differ greatly. We sought to determine whether or not physicians are utilized in prehospital care and to what extent they are present in different European countries. Methods: We collected information on 32 European countries by reviewing publications and sending questionnairesto authors of relevant articles as well as to officials of ministries of health (or equivalent), representatives of national societies in emergency medicine, or well-known experts in the specialty. Results: Thirty of the 32 of European countries we studied (94%) employ physicians in prehospital emergency medical services. In 17 of the 32 (53%), general practitioners also participate in prehospital emergency care. Emergency system models were described as Franco-German in 27 countries (84%), as hybrid in 17 (53%), and as Anglo-American in 14(44%). Multiple models were present simultaneously in 17 countries (53%). We were able to differentiate between national prehospital emergency systems with a novel classification based on tiers reflecting the degree of physician utilization in the countries. We also grouped the national systems by average population and area served. Conclusions: There are notable differences in system designs and intensity of physician utilization between different geographic areas, countries, and regions in Europe. Several archetypal models (Franco-German, hybrid, and AngloAmerican) exist simultaneously across Europe. (AU)

Physician empathy in Korean clinical contexts: developing a conceptual framework and exploring influencing factors.

PURPOSE: Despite its well-known clinical importance, physician empathy (PE) has been variably defined and its concepts among cultures are yet to be studied. This study aimed to develop a conceptual framework of PE and explore influencing factors on physicians' empathetic behavior in the Korean clinical context. METHODS: Forty-two faculty members and 67 residents participated in the two-round Delphi survey to arrive at a consensus regarding the conceptual framework of PE in 2019. To explore individual and external factors affecting physicians' empathetic behavior, a Likert scale questionnaire based on an initial free-text response was administered to the same participants. RESULTS: The conceptual framework of PE among Korean doctors consisted of basic communication skills and attitudes, cognitively understanding of patients' thoughts and emotions, and communicating the doctors' understandings to patients. Individual attributes and system- and patient-factors were revealed as influencing factors for PE in real practice. The former included communication ability, self-awareness and management, humanism, clinical competence, and good personality traits. Excessive workload, time constraints, aggressive attitudes, and negative preconceptions towards doctors were perceived as inhibiting or hindering empathy in patient care. CONCLUSION: PE in the Korean clinical context comprised behavioral and cognitive components. Individual attributes, as well as external factors including system- and patient-factors were identified to affect PE in clinical settings. Further studies are needed to enhance the conceptual clarity of PE and identify how to promote doctors' empathetic practice even in less favorable healthcare environments.

Cost consequences of task-shifting intravitreal injections from physicians to nurses in a tertiary hospital in Norway.

BACKGROUND: Anti-vascular endothelial growth factor is a medicine administered intravitreally by an injection to maintain visual acuity in patients with a variety of retinal diseases. The demand for this treatment has grown considerably in the westernized world the last two decades and will continue to increase due to an aging population. Because of the high volume, injections seize enormous resources and represent high costs for both hospitals and society. Task-shifting of injections from physicians to nurses may be a means to reduce such costs, however the magnitude of possible savings has been poorly investigated. To this end we investigated changes in the hospital costs per injection, six-year cost projections of physician- versus nurse-administered injections for a Norwegian tertiary hospital and we compared the societal costs per patient per year. METHODS: Patients (n = 318) were randomized to either physician- or nurse administered injections, and data were prospectively collected. Hospital costs per injection were calculated as the sum of training costs, personnel time and running expenses. The number of injections for the years 2014 - 21 from a Norwegian tertiary hospital was combined with age group specific injection prevalence and population projections to calculate cost projections for 2022 - 27. Societal costs per patient were calculated as the sum of hospital costs, transport costs for patients, caregivers' use of time, costs of ophthalmology consultations and community-based homecare. RESULTS: The hospital costs per injection were 5.5 € higher for physicians compared to nurses (281.6 € versus 276.1 €). Cost projections estimated an annual hospital saving of task-shifting of 48 921 € for 2022 - 27. Societal costs per patient did not differ significantly between the two groups (mean 4988 € vs 5418 €, p = 0.398). CONCLUSION: Task-shifting of injections from physicians to nurses can reduce hospital costs and increase the flexibility of physician resources. The annual savings are modest, but increased demand for injections might increase future cost savings. To achieve future savings for society, organizing ophthalmology consultations and injections on the same day to reduce the number of visits might be a solution.

Evolution of the Chief Medical Officer Role in Teaching Hospitals and Health Systems.

GOAL: Clinical physician leaders have become an increasingly important asset to hospitals and hospital systems in a changing healthcare environment. Specifically, the role of the chief medical officer (CMO) has expanded and evolved amid the shift to value-based payment models and sharpened focus on patient safety, quality, community engagement, and equity in healthcare, as well as a global pandemic. In light of these changes, this study examined the transformation of CMOs and similar roles and evaluated the current needs, challenges, and responsibilities of clinical leaders today. METHODS: The primary data source used in this analysis was a survey fielded to 391 clinical leaders in 290 Association of American Medical Colleges-member hospitals and health systems in 2020. In addition, this study compared responses to the 2020 survey with findings from two prior iterations of the survey from 2005 and 2016. The surveys collected information regarding demographics, compensation, administrative titles, qualifications for the position, and the scope of the role, among other questions. All surveys consisted of multiple-choice, free response, and rating questions. The analysis was conducted using frequency counts and percentage distributions. PRINCIPAL FINDINGS: Thirty percent of eligible clinical leaders responded to the 2020 survey. Twenty-six percent of the clinical leader respondents identified as female. Ninety-one percent of the CMOs were members of the senior management team in their hospital or health system. CMOs reported that they were responsible for five hospitals, on average, with 67% indicating they were responsible for more than 500 physicians. PRACTICAL APPLICATIONS: This analysis provides hospital and health systems with insight into the expanding scope and complexity of CMOs as they take on greater leadership responsibilities within their institutions amidst a shifting healthcare landscape. In reflecting on our results, hospital leaders can understand the current needs, barriers, and responsibilities of today's clinical leaders.

Association between acculturation and physician trust for internal migrants: A cross-sectional study in China.

BACKGROUND: Physician trust is a critical determinant of the physician-patient relationship and is necessary for an effective health system. Few studies have investigated the association between acculturation and physician trust. Thus, this study analyzed the association between acculturation and physician trust among internal migrants in China by using a cross-sectional research design. METHODS: Of the 2000 adult migrants selected using systematic sampling, 1330 participants were eligible. Among the eligible participants, 45.71% were female, and the mean age was 28.50 years old (standard deviation = 9.03). Multiple logistic regression was employed. RESULTS: Our findings indicated that acculturation was significantly associated with physician trust among migrants. The length of stay (LOS), the ability of speaking Shanghainese, and the integration into daily life were identified as contributing factors for physician trust when controlling for all the covariates in the model. CONCLUSION: We suggest that specific LOS-based targeted policies and culturally sensitive interventions can promote acculturation among Shanghai's migrants and improve their physician trust.

Zoom behavior during visual search modulates pupil diameter and reflects adaptive control states.

Adaptive gain theory proposes that the dynamic shifts between exploration and exploitation control states are modulated by the locus coeruleus-norepinephrine system and reflected in tonic and phasic pupil diameter. This study tested predictions of this theory in the context of a societally important visual search task: the review and interpretation of digital whole slide images of breast biopsies by physicians (pathologists). As these medical images are searched, pathologists encounter difficult visual features and intermittently zoom in to examine features of interest. We propose that tonic and phasic pupil diameter changes during image review may correspond to perceived difficulty and dynamic shifts between exploration and exploitation control states. To examine this possibility, we monitored visual search behavior and tonic and phasic pupil diameter while pathologists (N = 89) interpreted 14 digital images of breast biopsy tissue (1,246 total images reviewed). After viewing the images, pathologists provided a diagnosis and rated the level of difficulty of the image. Analyses of tonic pupil diameter examined whether pupil dilation was associated with pathologists' difficulty ratings, diagnostic accuracy, and experience level. To examine phasic pupil diameter, we parsed continuous visual search data into discrete zoom-in and zoom-out events, including shifts from low to high magnification (e.g., 1× to 10×) and the reverse. Analyses examined whether zoom-in and zoom-out events were associated with phasic pupil diameter change. Results demonstrated that tonic pupil diameter was associated with image difficulty ratings and zoom level, and phasic pupil diameter showed constriction upon zoom-in events, and dilation immediately preceding a zoom-out event. Results are interpreted in the context of adaptive gain theory, information gain theory, and the monitoring and assessment of physicians' diagnostic interpretive processes.

Interprofessional sense-making in the emergency department: A SenseMaker study.

BACKGROUND: Emergency Departments serve as a main entry point for patients into hospitals, and the team, the core of which is formed by doctors and nurses needs to make sense of and respond to the constant flux of information. This requires sense-making, communication, and collaborative operational decision-making. The study's main aim was to explore how collective, interprofessional sense-making occurs in the emergency department. Collective sense-making is deemed a precursor for adaptive capability, which, in turn, promotes coping in a dynamically changing environment. METHOD: Doctors and nurses working in five large state emergency departments in Cape Town, South Africa, were invited to participate. Using the SenseMaker® tool, a total of 84 stories were captured over eight weeks between June and August 2018. Doctors and nurses were equally represented. Once participants shared their stories, they self-analysed these stories within a specially designed framework. The stories and self-codified data were analysed separately. Each self-codified data point was plotted in R-studio and inspected for patterns, after which the patterns were further explored. The stories were analysed using content analysis. The SenseMaker® software allows switching between quantitative (signifier) and qualitative (descriptive story) data during interpretation, enabling more deeply nuanced analyses. RESULTS: The results focused on four aspects of sense-making, namely views on the availability of information, the consequences of decisions (actions), assumptions regarding appropriate action, and preferred communication methods. There was a noticeable difference in what doctors and nurses felt would constitute appropriate action. The nurses were more likely to act according to rules and policies, whereas the doctors were more likely to act according to the situation. More than half of the doctors indicated that they found it best to communicate informally, whereas the nurses indicated that formal communication worked best for them. CONCLUSION: This study was the first to explore the ED's interprofessional team's adaptive capability to respond to situations from a sense-making perspective. We found an operational disconnect between doctors and nurses caused by asymmetric information, disjointed decision-making approaches, differences in habitual communication styles, and a lack of shared feedback loops. By cultivating their varied sense-making experiences into one integrated operational foundation with stronger feedback loops, interprofessional teams' adaptive capability and operational effectiveness in Cape Town EDs can be improved.

Self-reported skills and self-confidence in point-of-care ultrasound: a cross-sectional nationwide survey amongst Finnish emergency physicians.

BACKGROUND: The use of point-of-care ultrasound (POCUS) is increasing. Numerous investigators have evaluated the learning curves in POCUS, but there are no published studies on how emergency physicians perceive their own competence level with this skill. METHODS: A nationwide survey amongst Finnish emergency physicians was conducted. The respondents reported their use of POCUS and how it has affected their clinical decision-making. The number of POCUS examinations performed was compared to the self-assessed skill level with different applications. Cut-off values were determined for the number of examinations required to acquire a good self-assessed skill level in each POCUS application. The correlation between self-confidence and the self-estimated skill level was analyzed. Several different statistical methods were used, such as Student's t-test, Pearson's correlation test, Loess method and ROC curve analysis. RESULTS: A total of 134 out of 253 Finnish emergency medicine specialists and residents (52%) responded to the survey. The most commonly used POCUS applications were POCUS-assisted procedures, pleural effusion and pneumothorax, inferior vena cava and lower extremity deep venous thrombosis. The initial rate of perceived skill acquisition was very steep with the curve flattening with greater skill and more experience. The number of examinations performed to reach a self-assessed good competence varied from seven to 75 with different applications. The lowest cut-off point for self-assessed good competence was obtained for rapid ultrasound for the shock and hypotension-protocol and the highest for focused cardiac examinations. There was an excellent correlation between self-confidence and the self-assessed skill level. CONCLUSIONS: The Finnish emergency practitioners' self-assessed development of POCUS skills parallels the previously published learning curves of POCUS. The correlation of self-confidence and the self-assessed skill level was found to be excellent. These findings add information on the development of perceived POCUS skills amongst emergency physicians and could complement a formal performance assessment.

Assessment of a Peer Physician Coaching Partnership Between a Designated Cancer Center Genetics Service and a Community Cancer Network Hospital.

Background: Patients with cancer seen in rural and underserved areas disproportionately face barriers to access genetic services. Genetic testing is critical to inform treatment decisions, for early detection of another cancer, and to identify at-risk family members who may benefit from screening and prevention. Objective: To examine medical oncologists' genetic testing ordering trends for patients with cancer. Design, Setting, and Participants: This prospective quality improvement study was performed in 2 phases over 6 months between August 1, 2020, and January 31, 2021, at a community network hospital. Phase 1 focused on observation of clinic processes. Phase 2 incorporated peer coaching from cancer genetics experts for medical oncologists at the community network hospital. The follow-up period lasted 9 months. Main Outcomes and Measures: The number of genetic tests ordered was compared between phases. Results: The study included 634 patients (mean [SD] age, 71.0 [10.8] years [range, 39-90 years]; 409 women [64.5%]; 585 White [92.3%]); 353 (55.7%) had breast cancer, 184 (29.0%) had prostate cancer, and 218 (34.4%) had a family history of cancer. Of the 634 patients with cancer, 29 of 415 (7.0%) received genetic testing in phase 1, and 25 of 219 (11.4%) received genetic testing in phase 2. Of the 29 patients who received testing in phase 1, 20 (69.0%) had germline genetic testing; 23 of 25 patients (92.0%) had germline genetic testing in phase 2. Uptake of germline genetic testing increased by 23.0% between phases, but the difference was not statistically significant (P = .06). Uptake of germline genetic testing was highest among patients with pancreatic cancer (4 of 19 [21.1%]) and ovarian cancer (6 of 35 [17.1%]); the National Comprehensive Cancer Network (NCCN) recommends offering genetic testing to all patients with pancreatic cancer and ovarian cancer. Conclusions and Relevance: This study suggests that peer coaching from cancer genetics experts was associated with an increase in ordering of genetic testing by medical oncologists. Efforts made to (1) standardize gathering of personal and family history of cancer, (2) review biomarker data suggestive of a hereditary cancer syndrome, (3) facilitate ordering tumor and/or germline genetic testing every time NCCN criteria are met, (4) encourage data sharing between institutions, and (5) advocate for universal coverage for genetic testing may help realize the benefits associated with precision oncology for patients and their families seeking care at community cancer centers.

Experience and perspectives of end-of-life care discussion and physician orders for life-sustaining treatment of Korea (POLST-K): a cross-sectional study.

BACKGROUND: This study aimed to identify the healthcare providers' experience and perspectives toward end-of-life care decisions focusing on end-of-life discussion and physician's order of life-sustaining treatment documentation in Korea which are major parts of the Life-Sustaining Treatment Act. METHODS: A cross-sectional survey was conducted using a questionnaire developed by the authors. A total of 474 subjects-94 attending physicians, 87 resident physicians, and 293 nurses-participated in the survey, and the data analysis was performed in terms of frequency, percentage, mean and standard deviation using the SPSS 24.0 program. RESULTS: Study results showed that respondents were aware of terminal illness and physician's order of life-sustaining treatment in Korea well enough except for some details. Physicians reported uncertainty in terminal state diagnosis and disease trajectory as the most challenging. Study participants regarded factors (related to relationships and communications) on the healthcare providers' side as the major impediment to end-of-life discussion. Study respondents suggested that simplification of the process and more staff are required to facilitate end-of-life discussion and documentation. CONCLUSION: Based on the study results, adequate education and training for better end-of-life discussion are required for future practice. Also, a simple and clear procedure for completing a physician's order of life-sustaining treatment in Korea should be prepared and legal and ethical advice would be required. Since the enactment of the Life-Sustaining Treatment Act, several revisions already have been made including disease categories, thus continuous education to update and support clinicians is also called for.

Physician-reported characteristics, representations, and ethical justifications of shared decision-making practices in the care of paediatric patients with prolonged disorders of consciousness.

BACKGROUND: Despite consensus about the importance of implementing shared decision-making (SDM) in clinical practice, this ideal is inconsistently enacted today. Evidence shows that SDM practices differ in the degree of involvement of patients or family members, or in the amount of medical information disclosed to patients in order to "share" meaningfully in treatment decisions. Little is known on which representations and moral justifications physicians hold when realizing SDM. This study explored physicians' experiences of SDM in the management of paediatric patients with prolonged disorders of consciousness (PDOC). Specifically, we focused on physicians' SDM approaches, representations, and ethical justifications for engaging in SDM. METHODS: We used a qualitative approach to explore the SDM experiences of 13 ICU physicians, paediatricians, and neurologists based in Switzerland who have been or were involved in the care of paediatric patients living with PDOC. A semi-structured interview format was used and interviews were audio-recorded and transcribed. Data were analysed through thematic analysis. RESULTS: We found that participants followed three main decision-making approaches: the "brakes" approach, characterized by maximized family's decisional freedom, though conditional to physician's judgment regarding the medical appropriateness of a treatment; the "orchestra director" approach, characterized by a multi-step decision-making process led by the main physician aimed at eliciting the voices of the care team members and of the family; and the "sunbeams" approach, characterized by a process oriented to reach consensus with family members through dialogue, where the virtues of the physician are key to guide the process. We also found that participants differed in the moral justifications sustaining each approach, citing the duty to respect parental autonomy, to invest in an ethics of care, and to employ physicians' virtues to guide the decision-making process. CONCLUSION: Our results show that physicians come to perform SDM in different ways, with several representations, and distinct ethical justifications. SDM training among health care providers should clarify the ductility of SDM and the several ethical motivations underpinning it, rather than insisting on the principle of respect for patient's autonomy as its only moral foundation.

Prognostic Conversations Between Parents and Physicians in the Pediatric Intensive Care Unit.

BACKGROUND: Up to 80% of pediatric intensive care unit (PICU) patients experience new morbidities upon discharge. Patients and families rely on clear communication to prepare for post-PICU morbidities. METHODS: Surveys were given at PICU discharge to parents and attending physicians of patients who developed multi-organ dysfunction within 24 hours of PICU admission and whose parents completed an initial survey 5 to 10 days after PICU admission. Participants were asked about prognostic conversations regarding PICU mortality; patient post-PICU physical, cognitive, and psychological morbidities; and parent post-PICU psychological morbidities. Parents also indicated whether they wanted more prognostic information. RESULTS: Forty-nine parents and 20 PICU attending physicians completed surveys for 49 patients. Thirty parent (61%) and 29 physician (59%) surveys reported participating in any prognostic conversations. Concordance between parents and physicians about prognostic conversations was slight (κ = 0.19). Parent (n = 22; 45%) and physician (n = 23; 47%) surveys most commonly reported prognostic conversations about post-PICU physical morbidities. Parents less commonly reported conversations about post-PICU cognitive morbidities (n = 10; 20%). According to parents, bedside nurses and physicians provided most prognostic information; social workers (54%) most commonly discussed parent psychological morbidities. Twenty-six parents (53%) requested more prognostic information. CONCLUSIONS: Most parents and physicians reported having prognostic conversations, primarily about post-PICU physical morbidities. More than half of parents wanted more information about potential post-PICU morbidities. More research is needed to understand how and when medical professionals should have prognostic conversations with parents.

COVID-19-related stress among emergency physicians: a scoping review protocol on the stressors and coping strategies.

OBJECTIVE: This scoping review aims to identify the COVID-19-related stressors and the corresponding coping strategies among emergency physicians during and following the pandemic. INTRODUCTION: In the midst of an unprecedented COVID-19 crisis, healthcare professionals confront a diverse set of difficulties. Emergency physicians are under immense pressure. They must provide frontline care and make quick decisions in a high-pressure environment. This can lead to a variety of physical and psychological stressors, including extended working hours, increased workload, personal risk of infection and the emotional toll of caring for infected patients. It is critical that they be informed of the numerous stressors they face, as well as the various coping methods accessible to them, in order to deal with these pressures. INCLUSION CRITERIA: This paper will summarise the findings of primary or secondary investigations on emergency physicians' stressors and coping strategies during and following the COVID-19 epidemic. All journals and grey literature in English and Mandarin published after January 2020 are eligible. METHODS: The Joanna Briggs Institute (JBI) method will be used to conduct the scoping review. A thorough literature search will be performed on OVID Medline, Scopus and Web of Science to find eligible studies, using the keywords related to emergency physicians, stress and coping strategies. Two reviewers will independently revise all of the full-text articles, extract data and evaluate the study quality. A narrative overview of the findings from included studies will be given. ETHICS AND DISSEMINATION: This review will involve secondary analysis of published literature, and therefore ethics approval is not required. The Preferred Reporting Items for Systematic reviews and Meta-Analyses checklist will be used to guide translation of findings. Results will be disseminated through peer-reviewed journals and presented in conferences via abstract and presentation.

Perceptions of the Brazilian obstetrics physicians about the term obstetric violence: a cross-sectional study.

INTRODUCTION: We observe a growing global discussion about the practices considered "obstetric violence" against women during pregnancy and childbirth. Otherwise, the indiscriminate subjective and lay interpretation of the term "obstetric violence" can lead to a misunderstanding among medical professionals. OBJECTIVE: This study aimed to describe the obstetrician's perceptions about the term "obstetric violence" and the medical groups affected negatively by the topic. METHODS: A cross-sectional study applied to Brazilian obstetrics physicians regarding their perceptions of "obstetric violence." RESULTS: From January to April 2022, we sent about 14,000 direct mail nationwide. A total of 506 participants responded. We observed that 374 (73.9%) participants consider the term obstetric violence nocive or harmful to professional practice. Furthermore, after Poisson regression, we described that the respondents who graduated before 2000 and from a private institution were significant and independent groups for the full or partial agreement that the term is nocive for the obstetricians in Brazil. CONCLUSION: We observed that almost three in four obstetrician participants consider the term "obstetric violence" nocive or harmful to professional practice, particularly in those who graduated before 2000 and from a private institution. The findings are relevant to propose further debates and strategies to mitigate the possible harms caused to the obstetrician team by the indiscriminate use of the term obstetric violence.

Exercise in bushfire smoke for high performance athletes: A Position Statement from the Australian Institute of SportEndorsed by Australasian College of Sport and Exercise Physicians (ACSEP) and Sport Medicine Australia (SMA).

OBJECTIVES: The frequency of bushfires in Australia is increasing and it is expected bushfire smoke will become a more prevalent phenomenon impacting air quality. The objective of this position statement is to provide guidance to the sport sector regarding exercise in air affected by bushfire smoke. DESIGN: This is position statement from the Australian Institute of Sport, based on a narrative review of the literature regarding bushfire smoke and its effects on health and exercise performance. METHODS: A narrative review of scientific publications regarding the effects of bushfire smoke on health and exercise performance. RESULTS: Bushfire smoke has negative impacts on health and performance. Athletes exercising at high intensity over a prolonged duration will increase their exposure to air pollutants. Athletes with a history of elevated airway responsiveness are likely to be at increased risk of an adverse response to bushfire smoke exposure. CONCLUSIONS: Athletes, coaches, support staff and sport organisations should monitor air quality (PM2.5 concentration) and make appropriate adjustments to training duration and intensity.

A Central Venous Catheter Line Misadventure: "Doctor why do I have a humming sound in my ear?"

We report a 32-year-old female patient who was referred to a tertiary care hospital in Muscat, Oman, in 2021 with an iatrogenic arteriovenous fistula (AVF) that presented as a neck swelling which developed few weeks after an attempt of central venous catheterisation through the right internal jugular vein. The fistula was corrected surgically with a successful outcome. AVF is an abnormal communication between an artery and vein which can occur as a congenital anomaly, after trauma or iatrogenic following central venous catheter or endovenous thermal ablation.
