Choosing Wisely (CW) campaigns globally have focused attention on the need to reduce low-value
care, which can represent up to 30% of the costs of healthcare.
Despite early enthusiasm for the CW initiative, few large-scale changes in rates of low-value care have been reported since the launch of these campaigns.
This paper by Jeremy M Grimshaw describes the Choosing Wisely De-Implementation Framework (CWDIF), a novel framework that builds on previous work in the field of implementation science and proposes a comprehensive approach to systematically reduce low-value care in both hospital and community settings and advance the science of de-implementation.
