Towards Advanced Practice in Medical Imaging: Reflections on Role Extension in Ghana
Objectives: This narrative review explores the feasibility and impact of role extension for radiographers as a strategy to address the critical shortage of radiologists in Ghana. It aims to assess the rationale, educational requirements, policy needs, and professional dynamics surrounding the implementation of advanced practice roles in medical imaging. The review also seeks to identify opportunities and challenges specific to the Ghanaian healthcare context and propose actionable recommendations to support policy and practice development.
Key Findings: The primary driver for radiographer role extension in Ghana is the significant imbalance between the demand for diagnostic services and the limited availability of radiologists, particularly in rural and underserved areas. Evidence from international contexts demonstrates that radiographers, with appropriate training, can perform advanced tasks such as image interpretation and reporting with accuracy comparable to radiologists. However, implementation in Ghana faces several barriers, including the absence of accredited training programs, lack of policy and regulatory frameworks, limited interprofessional collaboration, and professional skepticism. Key enablers include stakeholder engagement, investment in education, pilot program development, and continuous professional development. Role extension is also aligned with Ghana’s goals for universal health coverage and health workforce optimization.
Conclusion: Role extension in medical imaging holds substantial potential to transform diagnostic service delivery in Ghana. By expanding the scope of radiographic practice, the country can enhance healthcare access, reduce diagnostic delays, and improve patient outcomes. The success of this initiative depends on the establishment of structured training programs, clear policy frameworks, and collaborative professional cultures.
Implications for Practice: To operationalize role extension, Ghana must adopt a multifaceted approach: (1) develop and accredit postgraduate training programs for radiographers; (2) implement policy guidelines through collaboration between government, regulatory bodies, and professional associations; (3) foster interprofessional acceptance and cooperation; and (4) launch pilot programs to test feasibility and inform national scale-up. Investment in these areas will not only address existing service delivery gaps but also empower radiographers to contribute meaningfully to diagnostic care, thereby strengthening the resilience and responsiveness of Ghana’s healthcare system.
