Serious Illness Care Programme-contextual factors and implementation strategies: a qualitative study.

Health systems need multifaceted implementation strategies to move beyond the limited impact of clinician training in driving improvement in serious illness conversations. These include EHR-based data feedback, involvement of specialty leaders to message the programme and align incentives, and local champions to problem-solve frontline challenges longitudinally. Implementation of these strategies depended on a favourable institutional context. Greater attention to the influence of contextual factors and implementation strategies may enable sustained improvements in serious illness conversations at scale.
