Investment in research and improvement knowledge across the dimensions has been comparatively uneven, with little shared learning between researchers and professionals working to improve quality in one dimension about the value and efficacy of improvement approaches and methods used in others. Despite policy efforts to define quality in the round as safe, effective and patient-centred,2 3 and despite intermittent calls for patients to be involved in patient safety,4 the dimensions of quality do not have equal status within the improvement community, and patients and families do not play much part in patient safety: their input in this area is seen as subjective and less relevant to outcomes.
