The evolution of quality in healthcare: a diffusion of innovation perspective

Purpose This article reviews the history of “quality” in healthcare through the diffusion of innovation theoretical framework, focusing on quality as an innovation within this framework. Design/methodology/approach This article uses a qualitative critical review typology to review five key historical healthcare quality initiatives through Rogers' diffusion of innovation theoretical framework. Findings A qualitative critical review of quality in healthcare from a diffusion of innovation lens reveals three key insights: (1) engaging opinion leaders who oppose an innovation can improve implementation; (2) developing a brand for an innovation can accelerate its diffusion rates and (3) a planned diffusion approach is crucial for maximising public health impact. Research limitations/implications This qualitative critical review offers valuable insights; however, it is not an exhaustive review of the literature, and these outcomes could benefit from future research to support its findings and validate them across diverse healthcare settings. Practical implications The findings suggest the need to: (1) engage diverse perspectives to refine and enhance quality initiatives. (2) Develop a branding strategy to improve the diffusion of quality initiatives. (3) Create a system-level plan that considers the broader implications for healthcare systems. Originality/value This article provides practical guidance for healthcare professionals and policymakers, helping to improve the quality management of healthcare services. It introduces branding as a potential fifth key pillar, emphasising the involvement of opposing opinion leaders and the importance of planning in the diffusion process.
