Methods to Increase Reliability in Quality Improvement Projects

Although many quality improvement initiatives in health care see early and laudable success, 1 of the greatest challenges is sustaining the gains and avoiding the natural tendency of systems to revert to their original state, function, and outcomes. Reliability science describes a mathematical and systematic framework for understanding the level of reliability of interventions, and therefore the anticipated success and failure rate of both the steps of a process and the cumulative process overall. Successful utilization of this framework, along with the mindful organizing principles of high-reliability organizations, will facilitate ongoing and long-lasting improvement in outcomes. In this article, we describe practical methods to increase the reliability of interventions toward achieving and sustaining improvement goals.
