Teleradiology usage and user satisfaction with the telemedicine system operated by médecins sans frontières

Bringing MRI to low- and middle-income countries: Directions, challenges and potential solutions

The global disparity of magnetic resonance imaging (MRI) is a major challenge, with many low- and middle-income countries (LMICs) experiencing limited access to MRI. The reasons for limited access are technological, economic and social. With the advancement of MRI technology, we explore why these challenges still prevail, highlighting the importance of MRI as the epidemiology of disease changes in LMICs. In this paper, we establish a framework to develop MRI with these challenges in mind and discuss the different aspects of MRI development, including maximising image quality using cost-effective components, integrating local technology and infrastructure and implementing sustainable practices. We also highlight the current solutions-including teleradiology, artificial intelligence and doctor and patient education strategies-and how these might be further improved to achieve greater access to MRI.

Barriers and Facilitators Experienced During the Implementation of Web-Based Teleradiology System in Public Hospitals of the Northwest Ethiopia: An Interpretive Description Study

Introduction: Teleradiology allows distant facilities to electronically transmit images for interpretation, thereby bridging the radiology service gap between urban and rural areas. The technology improves healthcare quality, treatment options, and diagnostic accuracy. However, in low resource settings like Ethiopia, teleradiology services are limited, posing challenges for implementation. Therefore, this study is aimed at exploring the factors that facilitated or hindered the implementation of web-based teleradiology in the public hospitals of the South Gondar Zone, Northwest Ethiopia. Methods: In this study, a purposive sampling method was employed to select seventeen participants, including hospital managers, physicians, emergency surgeons, and radiologists, for an in-depth interview (IDI). The interviews were conducted from March to May 2023. A reflexive thematic analysis was conducted using an abductive coding technique at the semantic/explicit level. Data were collected through semistructured interviews conducted face-to-face and virtually, with audio recordings transcribed, translated, and analyzed using Open Code version 4.02 software. Trustworthiness was ensured through prolonged engagement, reflective journaling, and review by coauthors. Results: The study examined eight main themes, with barriers to sustainable teleradiology implementation falling into five categories: technological, organizational, environmental, individual, and workflow and communication. Conversely, identified facilitators included improved radiology service efficiency, system accessibility, collaboration opportunities, and user trust in the radiology ecosystem. Within each theme, factors with potential impacts on teleradiology system sustainability were identified, such as the lack of system handover mechanisms, absence of a central image consultation center, and inadequate staffing of full-time radiologists and technical personnel. Conclusions: The study highlights the positive user perception of a web-based teleradiology system's user-friendliness and efficiency. Overcoming challenges and leveraging facilitators are crucial for optimizing teleradiology and improving service delivery and patient outcomes. A centralized consultation center with dedicated radiologists and technical personnel is recommended for maximizing efficiency.

Fluoroscopy-Guided Metallic Foreign Body Removal: A Report of Three Cases and Literature Review

Ingested foreign objects that become trapped in the upper aerodigestive tract is a common issue that arises in Otolaryngology-Head and Neck Surgery practice. In these circumstances, it is advised to explore the neck using an external method to remove the item. However, locating the foreign body might be challenging. Not all metallic foreign body (MFB) patients require surgery, especially those without symptoms or complications. The standard X-ray and CT images are routinely examined for preoperative assessment and localization. Removal can be accomplished via flexible pharyngo-laryngoscopy or upper gastrointestinal endoscopy. Fluoroscopy is a widely accessible, minimally invasive, but underutilized tool during procedures. It offers an accurate intraoperative assessment of the foreign body in real-time. To allow the planning of a secure extraction pathway, the target should be radiopaque. In this report, we present three unique cases in which we used fluoroscopic imaging for guidance to remove a foreign body in the head and neck region in Prince Sultan Military Medical City in Riyadh, Saudi Arabia. In the first case, a young male presented with a history of foreign body sensation and odynophagia in the throat after eating a (shawarma) sandwich. In the second case, a six-year-old boy presented to the emergency department (ED) with epistaxis after being exposed to an air gun shot to his face. In the third case, a 40- year-old male presented after exposure to an air gun shot to the neck. After identification of the foreign body, all three patients were referred to Otolaryngology-Head and Neck. After radiological images have been done to confirm the presence of foreign objects, all three had a minimally invasive procedure to remove the metallic foreign bodies under fluoroscopic guidance without needing extensive surgery. All the procedures went well with no immediate complications with discharge on the same day. Fluoroscopy-guided removal of foreign bodies related to metabolic forging is a promising technique with several advantages, including real-time visualization, reduced invasiveness, and shorter recovery times. However, it is essential to weigh the benefits against the risks associated with radiation exposure and inherent limitations in detecting non-metallic objects. Further research and clinical studies are needed to optimize this technique and establish evidence-based guidelines for its application in the field of metabolic forging bodies.

The impact of computed radiography and teleradiology on patients' diagnosis and treatment in Mweso, the Democratic Republic of Congo

INTRODUCTION

High quality diagnostic imaging can provide increased diagnostic accuracy and help guide medical decision-making and management, however challenges for radiology in resource-limited settings are numerous. Diagnostic imaging and teleradiology have financial and logistical implications, so evidence of impact is crucial. We sought to test the hypothesis that the implementation of computed radiography with teleradiology consultation support will significantly change diagnoses and treatment plans in a resource limited setting.

METHOD

Paired before-after study to determine the therapeutic impact of an add-on diagnostic test. 'Preliminary Plan' and 'Final Plan' forms allowed direct comparison of diagnosis and treatment plans at initial consultation and following radiography and teleradiology. Consecutive consenting patients were included until the sample size (600) was reached. Changes in both diagnosis and treatment plan were analysed in the whole cohort, with sub-analyses of children aged <5 years, and cases of chest radiography.

RESULTS

Final analysis included 536 cases. Diagnosis changed following radiography and teleradiology in 62% of cases, and treatment plans changed in 61%. In chest radiography cases, 70% of diagnoses and 62% of treatment plans changed, while in children <5 years 66% of diagnoses and 58% of treatment plans changed. Reduced final treatment plans were most common for exploratory surgery (72% decrease), surgical orthopaedic intervention (62% decrease), and TB treatment (52% decrease), allowing more conservative medical or surgical management in 61 cases. Increased final treatment plans were highest in the orthopaedic and interventional surgery and referral categories. Of 42 cases requiring interventional surgery in the final plan, 26 (62%) were identified only after radiography and teleradiology. 16 additional cases were indicated for orthopaedic surgery, 10 cases required patient transfer, and TB treatment was indicated in 45 cases. A change in the original prescription plan occurred in 41% of 536 cases, with one or more prescriptions stopped in 28% of all cases.

CONCLUSION

We found that computed radiography with teleradiology had significant clinical value in this resource-limited setting, with the potential to affect both patient outcomes and treatment costs through providing improved diagnostics and avoiding unnecessary treatments and medications.

What do emergency medicine and burns specialists from resource constrained settings expect from mHealth-based diagnostic support? A qualitative study examining the case of acute burn care

BACKGROUND

Traumatic injury is a serious global health burden, particularly in low- and middle-income countries where medical care often lacks resources and expertise. In these contexts, diagnostic telemedicine could prove a cost effective tool, yet it remains largely underused here, and knowledge on its potential impact is limited. Particularly scarce is the view of the expert user physicians, and how they themselves relate to this technology.

METHODS

This qualitative study investigated tele-experts' (n = 15) views on the potential for image based teleconsultation to be integrated in trauma and emergency care services. A semi-structured interview guide was used to gather data concerning an mHealth app for burns diagnostics in the acute care setting, in the Western Cape, South Africa. Questions examined challenges and opportunities in user acceptance and outcomes, in specific case management and in the wider healthcare system. Resulting data were subject to qualitative content analysis.

RESULTS

Experts perceived remote diagnostic support through mHealth as linking directly to several key ideas in medicine, including barriers to care, medical culture and hierarchy, and medical ethics within a society. Ideas running through the data pertained to the widening and narrowing of inherent gaps in the healthcare system, and the formalisation of processes, practices and relationships, effected by the introduction of an app. Wide consensus was stated on positive outcomes such as increased education opportunities, improved professional relationships and a better ability to advise and diagnose, all further facilitated through greater ease of access. The belief was that these could achieve a narrowing of systemic divides within healthcare, although it was acknowledged that the possibility to induce the opposite effect also arose. Differing opinions were voiced relating to the involvement of allied health professionals and feedback.

CONCLUSION

Experts see several aspects to an mHealth app for remote diagnostic support which could enhance provision of trauma and emergency care in a resource poor setting, relating to reduced delays, streamlined care and improved outcomes. Attention is also drawn, however, to specifics of the environment which would demand further and careful consideration for success - time pressure, intensity and the wide range of subspecialties to be considered.

Tele-neurology in sub-Saharan Africa: A systematic review of the literature

BACKGROUND

The rapid advancement in telecommunications on the African continent has opened up avenues for improving medical care to underserved populations. Although the greatest burden of neurological disorders is borne by Low-and-Middle Income Countries (LMICs) including sub-Saharan Africa (SSA), there is a profound paucity of neurologists to serve the population. Telemedicine presents a promising avenue for effective mobilization and utilization of the few neurologists in Africa.

OBJECTIVE

To systematically review the published literature on the use of telemedicine for improved care and outcomes for patients with neurological disorders in SSA.

METHODS

We searched PubMed and Cochrane library from January 1, 1980 to April 30, 2017 using the following keywords: "Telemedicine neurology Africa", "Teleneurology Africa", "Telestroke Africa", "Telerehabilitation Africa", "Telemedicine for epilepsy", "Telemedicine for Parkinson's disease Africa", "Telemedicine for dementia Africa", "Telehealth neurology Africa". Our inclusion criteria were randomized controlled trials, or case series that reported the utilization of telemedicine for care/education of individuals with neurological disorders in sub-Saharan Africa.

RESULTS

This search yielded 6 abstracts. By consensus between two investigators, 1 publication met the criteria for inclusion and further review. The one study identified utilized telemedicine for the purpose of improving education/knowledge of 16 doctors and 17 allied health professionals in Parkinson's disease (PD) in Cameroon. The study noted feasibility and satisfaction of participants with telemedicine as well as improved knowledge base of participants after the educational course but noted access to healthcare by patients did not change. No studies have evaluated the use of telemedicine for care of patients with neurological disorders.

CONCLUSION

The indication is that teleneurology may be feasible in SSA and studies are needed to assess feasibility, acceptability, efficacy, cost-effectiveness of this promising discipline of neurology in these resource-limited settings. We propose the setting up of trans‑continental, inter-regional, intra-regional, and national networks of neurologists to utilize teleneurology platforms to improve the reach of neurology care in SSA.

Radiologic Professionalism in Modern Health Care

Modern radiology is at the forefront of technological progress in medicine, a position that often places unique challenges on its professional character. This article uses "Medical Professionalism in the New Millennium: A Physician Charter," a document published in 2002 and endorsed by several major radiology organizations, as a lens for exploring professional challenges in modern radiology. The three main tenets of the Charter emphasize patient welfare, patient autonomy, and the reduction of disparities in health care distribution. This article reviews the ways in which modern technology and financial structures potentially create stressors on professionalism in radiology, while highlighting the opportunities they provide for radiologists seeking to fulfill the professional goals articulated in the Charter. Picture archiving and communication systems (PACS) and voice recognition systems have transformed the speed of radiology and enhanced the ability of radiologists to improve patient care but also have brought new tensions to the workplace. Although teleradiology may improve global access to radiologists, it may also promote the commoditization of radiology, which diminishes the professional stature of radiologists. Social media and patient portals provide radiologists with new forums for interacting with the public and patients, potentially promoting patient welfare. However, patient privacy and autonomy are important considerations. Finally, modern financial structures provide radiologists with both entrepreneurial opportunities as well as the temptation for unprofessional conduct. Each of these advances carries the potential for professional growth while testing the professional stature of radiology. By considering the risks and benefits of emerging technologies in the modern radiology world, radiologists can chart an ethical and professional future path.

Quality Assurance of Teleconsultations in a Store-and-Forward Telemedicine Network - Obtaining Patient Follow-up Data and User Feedback

User surveys in telemedicine networks confirm that follow-up data are essential, both for the specialists who provide advice and for those running the system. We have examined the feasibility of a method for obtaining follow-up data automatically in a store-and-forward network. We distinguish between follow-up, which is information about the progress of a patient and is based on outcomes, and user feedback, which is more general information about the telemedicine system itself, including user satisfaction and the benefits resulting from the use of telemedicine. In the present study, we were able to obtain both kinds of information using a single questionnaire. During a 9-month pilot trial in the Médecins Sans Frontières telemedicine network, an email request for information was sent automatically by the telemedicine system to each referrer exactly 21 days after the initial submission of the case. A total of 201 requests for information were issued by the system and these elicited 41 responses from referrers (a response rate of 20%). The responses were largely positive. For example, 95% of referrers found the advice helpful, 90% said that it clarified their diagnosis, 94% said that it assisted with management of the patient, and 95% said that the telemedicine response was of educational benefit to them. Analysis of the characteristics of the referrers who did not respond, and their cases, did not suggest anything different about them in comparison with referrers who did respond. We were not able to identify obvious factors associated with a failure to respond. Obtaining data by automatic request is feasible. It provides useful information for specialists and for those running the network. Since obtaining follow-up data is essential to best practice, one proposal to improve the response rate is to simplify the automatic requests so that only patient follow-up information is asked for, and to restrict user feedback requests to the cases being assessed each month by the quality assurance panel.
