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

Area of Science:

• Health Services Research
• Systems Engineering
• Patient Safety Science

Background:

• The US Agency for Healthcare Research and Quality initiated Patient Safety Learning Laboratories (PSLLs) in 2014.
• PSLLs employ systems perspectives and engineering approaches to address patient safety challenges.

Purpose of the Study:

• To advance patient safety research through a novel initiative.
• To implement and evaluate systems engineering methodologies in healthcare settings.

Main Methods:

• A 5-phase systems engineering methodology including problem analysis, design, development, implementation, and evaluation.
• Integration of diverse methods such as human-centered design and AI-driven analytics.

Main Results:

• Demonstrated decreases in patient mortality and adverse drug events.
• Improved diagnostic accuracy, reduced medication errors, and enhanced early detection of adverse events.
• Significant reduction in prenatal adverse events.

Conclusions:

• PSLLs have developed evidence-based, scalable interventions to mitigate patient harm.
• These interventions strengthen healthcare delivery, improving safety, efficiency, and effectiveness.
• PSLLs positively impact societal health outcomes, healthcare organizations, providers, and patients.
