Understanding implementation science in medical radiation sciences

Radiography, like many allied health professions, faces persistent challenges in translating evidence and innovation into routine clinical practice. Despite a strong foundation in evidence-based practice, the adoption of new technologies, protocols, and models of care is often inconsistent, delayed, or un-sustained. This paper introduces Implementation science, which offers a key, yet underutilised approach for advancing radiographic practice by focusing on how evidence-based interventions are adopted, integrated, and sustained in real-world settings.

We present a conceptual overview of implementation science frameworks with particular relevance to radiography e.g. technology, devices and service improvement. Key frameworks considered include the Consolidated Framework for Implementation Research (CFIR), Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM), the Non-adoption, Abandonment, Scale-up, Spread, and Sustainability (NASSS) framework, the Theoretical Domains Framework (TDF), and Normalisation Process Theory (NPT). Each is appraised for its focus, strengths, and applicability to common implementation challenges in radiography. The frameworks highlight different but complementary perspectives, for example CFIR and TDF emphasise multilevel determinants of behaviour and RE-AIM structures evaluation of implementation outcomes. Applied examples from radiography and allied health illustrate how these approaches can be used to diagnose barriers, design strategies, and evaluate implementation efforts.

Implementation science provides a rich methodological and theoretical toolkit for strengthening radiography research. By applying these frameworks, studies can move beyond questions of clinical efficacy to address the practical realities of translation, adoption and sustainability.

Embedding implementation science within radiographic research, practice, and education can support more systematic and context-sensitive translation. This shift enables the profession to progress from demonstrating clinical potential to delivering sustained improvements in service delivery, patient safety, and professional practice.
