Longitudinal study of ICUs showing that team learning investment produced worse short-term performance but significantly better outcomes over time — after three years, units with higher team learning (and higher psychological safety) had 18% lower mortality rates than those with lower team learning. The finding directly challenges the implicit assumption that learning benefits should be immediate, and provides some of the strongest long-term outcome evidence for PS in healthcare. The temporal lag between investment and return has important practical implications: organisations that evaluate PS interventions on short-term performance metrics will systematically undervalue them.
