Healthcare innovations can take a variety of forms, ranging from new medical treatments or diagnostic devices through to novel professional practices and changes in the delivery of care and the design of patient pathways. Extensive research demonstrates that in the healthcare sector the benefits of many such innovations are not fully realised, and that innovations of proven value often fail to spread - resulting in less efficient healthcare services and lower quality of care. Our research projects therefore focus on the social, professional and organisational barriers to the effective diffusion and utilisation of innovations.
