There is evidence that practitioners applying quality improvements often adapt the improvement method or the change they are implementing, either unknowingly, or intentionally to fit their service or situation. This has been observed especially in programs seeking to spread or ‘scale up’ an improvement change to other services. Sometimes their adaptations result in improved outcomes, sometimes they do not, and sometimes they do not have data make this assessment or to describe the adaptation. The purpose of this paper is to summarize key points about adaptation and context discussed at the Salzburg Global Seminar in order to help improvers judge when and how to adapt an improvement change. It aims also to encourage more research into such adaptations to develop our understanding of the when, why and how of effective adaptation and to provide more research informed guidance to improvers.

The paper gives examples to illustrate key issues in adaptation and to consider more systematic and purposeful adaptation of improvements so as to increase the chances of achieving improvements in different settings for different participants. We describe methods for assessing whether adaptation is necessary or likely to reduce the effectiveness of an improvement intervention, which adaptations might be required, and methods for collecting data to assess whether the adaptations are successful. We also note areas where research is most needed in order to enable more effective scale up of quality improvements changes and wider take up and use of the methods.
