Health care systems around the world are seeking system-level interventions to improve
the quality and safety of care because of increasing awareness that many patients
do not receive recommended therapies or suffer preventable complications. This has
also been motivated by a drive to deliver health care more cost-effectively, and to
be more accountable to payers and other stakeholders. The Keystone Project in Michigan
is one example of a large-scale system-level initiative that successfully changed
the “culture of safety” in the intensive care units of participating hospitals and
led to improvements in both process outcomes and clinical outcomes. This article discusses
factors that contributed to the success of the Keystone Project and also considers
its economic implications. There are also recommendations for the design and evaluation
of future system-level quality improvement programs.
