Impact of Merit-Based Immigration Policies on Brain Drain From Low- and Middle-Income Countries

Growing the global cancer care system: success stories from around the world and lessons for the future

Despite major biomedical advancements in various realms of oncology, the benefits of these developments are not equitably distributed, particularly in underresourced settings. Although much work has described the challenges and systemic barriers in global cancer control, in this article we focus on success stories. This article describes clinical care delivered at Rwanda's Butaro Cancer Center of Excellence, the cancer research collaborations under India's National Cancer Grid, and the efforts of Latin America's Institute of Cancer of São Paulo in advancing cancer care and training. These examples highlight the potential of strategic collaborations and resource allocation strategies in improving cancer care globally. We emphasize the critical role of partnerships between physicians and allied health professionals, funders, and policy makers in enhancing access to treatment and infrastructure, advancing contextualized research and national guidelines, and establishing regional and global collaborations. We also draw attention to challenges faced in diverse global settings and outline benchmarks to measure success in the fight against cancer.

Provision of Food Allergy Care in the United Kingdom and United States: Current Issues and Future Directions

Food allergy (FA) is a growing issue worldwide. The United Kingdom and United States are high-income, industrialized countries with reported increases in FA prevalence over the past few decades. This review compares delivery of FA care in the United Kingdom and United States and each country's response to the heightened demand and disparities for FA services. In the United Kingdom, allergy specialists are scarce and general practitioners (GPs) provide most allergy care. Whereas the United States has more allergists per capita than the United Kingdom, there is still a shortage of allergy services owing to the greater reliance on specialist care for FA in America and wide geographic variation in access to allergist services. Currently, generalists in these countries lack the specialty training and equipment to diagnose and manage FA optimally. Moving forward, the United Kingdom aims to enhance training for GPs so they may provide better quality frontline allergy care. In addition, the United Kingdom is implementing a new tier of semi-specialized GPs and increasing cross-center collaboration through clinical networks. The United Kingdom and United States aim to increase the number of FA specialists, which is critical at a time of rapidly expanding management options for allergic and immunologic diseases requiring clinical expertise and shared decision-making to select appropriate therapies. While these countries aim to grow their supply of quality FA services actively, further efforts to build clinical networks and perhaps recruit international medical graduates and expand telehealth services are necessary to reduce disparities in access to care. For the United Kingdom in particular, increasing quality services will require additional support from the leadership of the centralized National Health Service, which remains challenging.

Impact of Magnetic Resonance Imaging on Healthcare in Low- and Middle-Income Countries

Magnetic resonance imaging (MRI) played a significant role in the digital health platforms that influenced and supported modern medicine. However, there is a shortage of MRI in low- and middle-income countries (LMICs). The International Society of Radiology offers a detailed plan for LMICs to advance imaging quality in the global health agenda. The overarching objective of this scoping review was to determine the impact of MRI in healthcare in LMICs. This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify available evidence. We systematically searched four academic databases for peer-reviewed literature published between 2018 and 2021, namely, Medline, PubMed, Web of Science, and Scopus, as well as Google Scholar as a source for gray literature. The search identified 54 articles. We identified a range of reasons for introducing MRI in LMICs. Nonetheless, some challenges to accepting MRI as a method of healthcare have been reported, including technological, regulatory, and economical challenges. To implement the proposed plan, the involvement of professional and international organizations is considered crucial. The establishment of an International Commission on Medical Imaging under the umbrella of international organizations is suggested and collaboration with other diagnostic disciplines is encouraged to raise awareness of the importance of upscale diagnostics at large and to foster its integration into the care pathway globally.

Understanding the challenges of delivering radiotherapy in low- and middle-income countries in Africa

BACKGROUND

Access to high quality radiotherapy (RT) continues to be a major issue across Africa with Africa having just 34% of its optimal capacity.

METHODS

We co-developed a survey with clinical, academic and policy stakeholders designed to provide a structured assessment of the barriers and enablers to RT capacity building in Africa. The survey covered nine key themes including funding, procurement, education and training. The survey was sent to RT professionals in 28 countries and the responses underwent qualitative and quantitative assessment.

RESULTS

We received completed questionnaires from 26 African countries. Funding was considered a major issue, specifically the lack of a ring fenced funds from the Ministry of Health for radiotherapy and the consistency of revenue streams which relates to a lack of prioritisation for RT. In addition to a significant shortfall in RT workforce disciplines, there is a general lack of formal education and training programmes. 13/26 countries reported having some IAEA support for RT for education and training. Solutions identified to improve access to RT include a) increasing public awareness of its essential role in cancer treatment; b) encouraging governments to simplify procurement and provide adequate funding for equipment; c) increasing training opportunities for all radiotherapy disciplines and d) incentivizing staff retention.

CONCLUSION

This survey provides unique information on challenges to delivering and expanding radiotherapy services in Africa. The reasons are heterogonous across countries but one key recommendation would be for national Cancer Control plans to directly consider radiotherapy and specifically issues of funding, equipment procurement, servicing and training.

POLICY SUMMARY

The study demonstrates the importance of mixed methods research to inform policy and overcome barriers to radiotherapy capacity and capability in LMICs.

International Neurosurgery: The Role for Collaboration

The global death toll from lack of access to basic surgical care is three times as much as for tuberculosis, HIV and malaria combined. Patients dying of curable neurosurgical conditions solely because of inadequacy or absence of neurosurgical infrastructure is an issue deserving immediate attention and action. Global neurosurgery is an important step forward in this regard, under which different models of collaboration between HICs and LMICs aim to increase both the number of neurosurgeons as well the quality of neurosurgical care available in these countries through arranging surgical camps, providing neurosurgical training and education, and restructuring the health system in these countries in order to create an environment conducive to the provision of the highest form of neurosurgical care. Despite the many challenges faced by LMICs in furthering neurosurgery programs such as poor resource allocation, brain drain, turbulent socioeconomic conditions, limited training facilities, and population explosion, data now being reported from LMICs the world over, exemplifies the immense positive impact that collaborations have had over the last few decades in improving neurosurgical capacity and infrastructure. So far, conventional methods of collaboration (i.e. neurosurgical missions to LMICs and training of neurosurgeons in HICs) have been effective in progressively bringing about the desired change in LMICs. However, these methods have been limited by a finite funding, pushing the global neurosurgical community to look for alternatives such as online curricula, task shifting and sharing, and long distance mentor-mentee relationships. In this review, we aim to provide an update on the current state of neurosurgical collaborations and identify the barriers in the way of collaborations and what alternative models of collaboration might be used to overcome them..

A SWOT analysis of artificial intelligence in diagnostic imaging in the developing world: making a case for a paradigm shift

Diagnostic imaging (DI) refers to techniques and methods of creating images of the body’s internal parts and organs with or without the use of ionizing radiation, for purposes of diagnosing, monitoring and characterizing diseases. By default, DI equipment are technology based and in recent times, there has been widespread automation of DI operations in high-income countries while low and middle-income countries (LMICs) are yet to gain traction in automated DI. Advanced DI techniques employ artificial intelligence (AI) protocols to enable imaging equipment perceive data more accurately than humans do, and yet automatically or under expert evaluation, make clinical decisions such as diagnosis and characterization of diseases. In this narrative review, SWOT analysis is used to examine the strengths, weaknesses, opportunities and threats associated with the deployment of AI-based DI protocols in LMICs. Drawing from this analysis, a case is then made to justify the need for widespread AI applications in DI in resource-poor settings. Among other strengths discussed, AI-based DI systems could enhance accuracies in diagnosis, monitoring, characterization of diseases and offer efficient image acquisition, processing, segmentation and analysis procedures, but may have weaknesses regarding the need for big data, huge initial and maintenance costs, and inadequate technical expertise of professionals. They present opportunities for synthetic modality transfer, increased access to imaging services, and protocol optimization; and threats of input training data biases, lack of regulatory frameworks and perceived fear of job losses among DI professionals. The analysis showed that successful integration of AI in DI procedures could position LMICs towards achievement of universal health coverage by 2030/2035. LMICs will however have to learn from the experiences of advanced settings, train critical staff in relevant areas of AI and proceed to develop in-house AI systems with all relevant stakeholders onboard.

National cancer control plans across the Eastern Mediterranean region: challenges and opportunities to scale-up

National cancer control planning is crucial for countries in the WHO Eastern Mediterranean region. This region is challenged with an increase in cancer incidence leading to substantial disease burden, premature deaths, and increasing health-care costs in most countries. Huge inequity in cancer control planning and implementation exists between and within the countries. Over half of the countries (12 [55%] of 22) have standalone comprehensive National Cancer Control Plans and six (27%) have non-communicable disease plans that include cancer. The implementation of cancer plans has common challenges related to weak governance structure, few coordination mechanisms within countries, and inadequate human and financial resources. In most countries, the plan is not costed. Yet, the majority of countries (20 [91%]) reported having fully or partially funded plans. Additionally, political instability and conflicts affecting over half of the countries in the Eastern Mediterranean region have enormously affected cancer planning and implementation, both among the affected countries and those that host large numbers of refugees. In this Policy Review, we used the WHO regional framework for action on cancer to systematically analyse the status of cancer control planning and implementation across the six domains of cancer control, from prevention to palliation. We highlight the gaps, and the opportunities for bridging these gaps, to achieve scale-up on implementation of cancer control programmes in the Eastern Mediterranean region.

How to improve access to medical imaging in low- and middle-income countries ?

Imaging has become key in the care pathway of communicable and non-communicable diseases. Yet, there are major shortages of imaging equipment and workforce in low- and middle-income countries (LMICs). The International Society of Radiology outlines a plan to upscale the role of imaging in the global health agenda and proposes a holistic approach for LMICs. A generic model for organising imaging services in LMICs via regional Centres of Reference is presented. The need to better exploit IT and the potential of artificial intelligence for imaging, also in the LMIC setting, is highlighted. To implement the proposed plan, involvement of professional and international organisations is considered crucial. The establishment of an International Commission on Medical Imaging under the umbrella of international organisations is suggested and collaboration with other diagnostic disciplines is encouraged to raise awareness of the importance to upscale diagnostics at large and to foster its integration into the care pathway globally.

Practical considerations for prostate hypofractionation in the developing world

External beam radiotherapy is an effective curative treatment option for localized prostate cancer, the most common cancer in men worldwide. However, conventionally fractionated courses of curative external beam radiotherapy are usually 8-9 weeks long, resulting in a substantial burden to patients and the health-care system. This problem is exacerbated in low-income and middle-income countries where health-care resources might be scarce and patient funds limited. Trials have shown a clinical equipoise between hypofractionated schedules of radiotherapy and conventionally fractionated treatments, with the advantage of drastically shortening treatment durations with the use of hypofractionation. The hypofractionated schedules are supported by modern consensus guidelines for implementation in clinical practice. Furthermore, several economic evaluations have shown improved cost effectiveness of hypofractionated therapy compared with conventional schedules. However, these techniques demand complex infrastructure and advanced personnel training. Thus, a number of practical considerations must be borne in mind when implementing hypofractionation in low-income and middle-income countries, but the potential gain in the treatment of this patient population is substantial.

Cancer research in the 57 Organisation of Islamic Cooperation (OIC) countries, 2008-17

Background and objectives

The 57 countries of the Organisation of Islamic Cooperation (OIC) are experiencing rapid increases in their burden of cancer. The First Ladies Against Cancer meeting at the 2016 OIC meeting in Istanbul committed to the importance of cancer control and the need for more evidence to support national cancer control planning (NCCP). Strong research systems are a crucial aspect of NCCP, but few data exist to support policy-makers across this political grouping

Methodology

We identified all cancer research papers from OIC countries in the Web of Science from 2008 to 2017 with a filter based on journal names and title words, with high precision and recall. We analysed the country outputs, the cancer sites investigated, the types of research, sources of funding and the citations to the papers.

Results

There were 49,712 cancer research papers over this period. The leading countries in terms of output were Turkey, Iran, Egypt and Malaysia, but the most cited papers were from Qatar, Indonesia and Saudi Arabia. International collaboration was low, except in Qatar and the United Arab Emirates. The site-specific cancers accounting for most research were breast and blood, correlating with their disease burden in the OIC countries, but lung, cervical and oesophageal cancers were relatively under-researched. Most funding from within the OIC countries was from their own university sector.

Conclusion

Cancer is seriously under-researched in most of the OIC countries. This will undermine the ability of these countries and OIC as a whole to deliver on better cancer control for their populations. New policies, OIC leadership and funding are urgently needed to address this situation.

Oncology Medical Training and Practice: Managing Jordan's Brain Drain Through Brain Train-The King Hussein Cancer Center Experience

PURPOSE

The medical education system in Jordan is one of the most advanced education systems in the Middle East. Yet many medical school graduates leave the country to seek specialty and subspecialty education and training abroad, and the majority of graduates continue their careers there.

METHODS

We explored reasons behind this so-called "brain drain" and how to slow it, along with capacity building opportunities and strategies for better local training.

RESULTS

By taking advantage of various international collaborative opportunities, the King Hussein Cancer Center has managed to offer strong local training programs and an enhanced working environment, which has enabled us to improve the educational level of our graduates so they can help staff the Center, the country, and the region.

CONCLUSION

Strong local training programs coupled with international partnerships can result in better training for physicians and offset the problem of brain drain without putting any restraints on the graduates.
