From Experiment to Excellence: The Impact of Patient Safety Learning Laboratories

To rapidly advance patient safety research, in 2014 the US Agency for Healthcare Research and Quality launched a radically different research initiative by supporting patient safety learning laboratories (PSLLs) using systems perspectives and engineering approaches to advance patient safety. The 5-phase systems engineering methodology uses diverse methods and devotes particular attention to health care safety problem analysis, followed by design, development, implementation, and evaluation. PSLL projects have demonstrated decreases in mortality as well as increases in diagnostic accuracy, reduction in adverse drug events, decreased medication errors, improved early detection of adverse events, and reduction in the number of prenatal adverse events. PSLLs have developed guidance and resources to prevent as well as mitigate patient harm and improve the safety, efficiency, and effectiveness of health care delivery. By fusing approaches ranging from human-centered design to AI-driven analytics applied to health services research, PSLLs have produced influential, evidence-based, scalable interventions that strengthen health care delivery processes and improve outcomes for society, health care organizations, providers, and-most importantly-patients and their families.
