Operational challenges and collaborative solutions in radiology image interpretation: perspectives from imaging departments in a low-resource setting

INTRODUCTION

Medical imaging's critical role in diagnosis requires prompt and precise image interpretation. Numerous radiology departments, especially in low-resourced settings, encounter challenges such as a shortage of radiologists in their operational setup. This study explored the perceptions of radiographers and radiologists from low-resourced departments in a single country regarding operational challenges and potential solutions in image interpretation.

METHODS

A qualitative approach was utilised, involving heads of departments, senior radiographers, and radiologists with a minimum of 5 years of experience, from three major state referral hospitals. Face-to-face, semi-structured interviews were conducted in November 2022, using an interview guide that included questions on the challenges encountered during image interpretation and the proposed solutions. Data analysis was conducted using Atlas.ti version 9.0, following the four-step content analysis method. All participants willingly provided consent to participate in the study.

RESULTS

Ten participants, comprising two radiologists and eight radiographers participated in the study. The research identified three main themes: image interpretation pathways, image interpretation operational challenges and proposed solutions for image interpretation. In addition, a total of 10 subthemes were generated from the three main themes.

CONCLUSION

The study revealed critical challenges and the need to explore the formal inclusion of radiographers in image interpretation, as a way to improve efficiency. However, a comprehensive assessment of the image interpretation system, encompassing radiographers' knowledge and competence, is recommended for context-specific, empirical-based modifications to enhance service provision.

Radiology image interpretation services in a low-resource setting: Medical doctors' experiences and the potential role of radiographers

INTRODUCTION

Medical doctors can encounter significant challenges in both the radiology image interpretation service and their ability to interpret images to promote effective patient management. This study aimed to explore the experiences of medical doctors in a low-resource setting regarding the image interpretation service received in state-funded hospitals and the potential role of radiographers.

METHODS

A qualitative approach with a descriptive phenomenology design was employed. Thirteen medical officers and medical interns, with a maximum of three years of experience, were purposively selected from three state-funded hospitals. Semi-structured interviews were conducted in English, and data analysis followed the conventional content analysis method using Atlas.ti for Windows (version 9).

RESULTS

Three main themes emerged from the data. The first theme was a poor image interpretation service which highlighted issues such as long turnaround times for image reporting and compromised patient management. The second theme was training and support deficiency which revealed the inadequacy of image interpretation training and the need for additional on-the-job support. The third theme was the inconspicuous radiographer role which showcased the potential opportunities for radiographers to aid in filling the gaps in the image interpretation system.

CONCLUSION

Medical doctors in this low-resource setting experience significant delays in radiology image interpretation, leading to compromised patient management. Their training in image interpretation is inadequate, and they often lack on-the-job support. Radiographers potentially play a role in image interpretation which may provide solutions to these contextual challenges.

IMPLICATIONS FOR PRACTICE

There is a need to review and develop a comprehensive image interpretation system that effectively supports medical doctors in image interpretation, possibly involving the collaboration of radiographers.

Virtual healthcare services and digital health technologies deployed during coronavirus disease 2019 (COVID-19) pandemic in South Africa: a systematic review

Aims

To identify virtual healthcare services and digital health technologies deployed in South Africa during coronavirus disease 2019 (COVID-19) and the challenges associated with their use.

Methods

To determine the status of digital health utilization during COVID-19 in South Africa, the preferred reporting items for systematic reviews and meta-analyses model was used to perform a systematic and in-depth critical analysis of previously published studies in well-known and trusted online electronic databases using specific search keywords words that are relevant to this study. We selected published peer-reviewed articles available from the onset of COVID-19 to July 2021.

Results

Total of 24 articles were included into this study. This study revealed that South Africa adopted digital technologies such as SMS-based solutions, mobile health applications, telemedicine and telehealth, WhatsApp-based systems, artificial intelligence and chatbots and robotics to provide healthcare services during COVID-19 pandemic. These innovative technologies have been used for various purposes including screening infectious and non-infectious diseases, disease surveillance and monitoring, medication and treatment compliance, creating awareness and communication. The study also revealed that teleconsultation and e-prescription, telelaboratory and telepharmacy, teleeducation and teletraining, teledermatology, teleradiology, telecardiology, teleophthalmology, teleneurology, telerehabilitation, teleoncology and telepsychiatry are among virtual healthcare services delivered through digital health technologies during COVID-19 in South Africa. However, these smart digital health technologies face several impediments such as infrastructural and technological barriers, organization and financial barriers, policy and regulatory barriers as well as cultural barriers.

Conclusion

Although COVID-19 has invigorated the use of digital health technologies, there are still some shortcomings. The outbreak of pandemics like COVID-19 in the future is not inevitable. Therefore, we recommend increasing community networks in rural areas to bridge the digital divide and the modification of mHealth policy to advocate for the effective use of innovative technologies in healthcare and the development of sustainable strategies for resources mobilization through private-public partnerships as well as joining available international initiatives advocating for smart digital health.

Assessment of final-year medical students' performance in diagnosing critical findings on chest X-ray

Purpose

Due to the recently emerging shortage in medical staff during the novel corona virus pandemic, several countries have rushed their undergraduate medical students into the emergency department. The accuracy of diagnosing critical findings on X-rays by senior medical students is not well assessed. In this study, we aim to assess the knowledge and accuracy of undergraduate final-year medical students in diagnosing life-threatening emergency conditions on chest x-ray.

Method

This is a cross-sectional nationwide survey across all medical schools in Jordan. Through an electronic questionnaire, participants were sequentially shown a total of six abnormal X-rays and one normal. For each X-ray, participants were asked to choose the most likely diagnosis, and to grade the degree of self-confidence regarding the accuracy of their answer in a score from 0 (not confident) to 10 (very confident).

Results

We included a total of 530 participants. All participants answered at least six out of seven questions correctly, out of them, 139 (26.2%) participants answered all questions correctly. Pneumoperitoneum was the highest correct answer (93.8%), whereas flail chest was the least correctly answered case with only 310 (58.5%) correct answers. Regarding self-confidence for each question, 338 participants (63.8%) reported very high overall self-confidence level. Answers related to tension pneumothorax had the highest confidence level.

Conclusion

Senior Jordanian medical students showed good knowledge with high confidence levels in diagnosing life-threatening conditions on chest x-rays, supporting their incorporation in the emergency department during pandemics and confirming the reliability of information they can extract.
