PurposeThe purpose of this study is to present a quality improvement approach titled “Picture-Understanding-Action” used in Ireland to enhance the role of healthcare boards in the oversight of healthcare quality and its improvement.Design/methodology/approachThe novel and practical “Picture-Understanding-Action” approach was implemented using the Model for Improvement to iteratively introduce changes across three quality improvement projects. This approach outlines the concepts and activities used at each step to support planning and implementation of processes that allow a board to effectively achieve its role in overseeing and improving quality. This approach matured over three quality improvement projects.FindingsThe “Picture” included quantitative and qualitative aspects. The quantitative “Picture” consisted of a quality dashboard/profile of board selected outcome indicators representative of the health system using statistical process control (SPC) charts to focus discussion on real signals of change. The qualitative picture was based on the experience of people who use and work in health services which “people-ised” the numbers. Probing this “Picture” with collective grounding, curiosity and expert training/facilitation developed a shared “Understanding”. This led to “Action(s)” from board members to improve the “Picture” and “Understanding” (feedback action), to ask better questions and make better decisions and recommendations to the executive (feed-forward action). The Model for Improvement, Plan-Do-Study-Act cycles and a co-design approach in design and implementation were key to success.Originality/valueTo the authors’ knowledge, this is the first time a board has undertaken a quality improvement (QI) project to enhance its own processes. It addresses a gap in research by outlining actions that boards can take to improve their oversight of quality of care.
