LHS connections
Common approach
Quality improvement is episodic and often local, while a Learning Health System is continuous and system-wide. In an LHS, QI is embedded within an ongoing learning loop rather than treated as a standalone activity.
Quality Improvement
Can we improve this process?
Audits retrospectively check performance, whereas an LHS learns from performance and adapts, providing a more forward-thinking approach.
Audits
Are we compliant?
An LHS learns from real-world practice, integrates evidence generation into routine care, and shortens the gap between discovery and implementation.
Traditional research
What new knowledge can we generate?
While PDSA is a tool, an LHS is the system that enables continuous PDSA at scale. An LHS operates across multiple services, is supported by system-level data, is continuously repeated, and is designed to scale.
Plan-Do-Study-Act (PDSA)
Does this small change work?
Evaluation tells you whether something worked. A LHS ensures you are always learning whether things are working. It's prospective and continuous, embedded in everyday practice rather than occurring after the fact.
Evaluation
Did it work? For whom? And why?
