qualityimprovement

Quality improvement (QI) is a systematic, formal approach to analyzing practice and outcomes and to making changes that lead to observable improvement in quality and safety. In healthcare and industry, QI emphasizes incremental, iterative changes rather than one-time reforms. Core elements include defining a clear aim, collecting data to measure performance, testing changes on a small scale, and studying the results before wider implementation.

Common frameworks include the Plan-Do-Study-Act (PDSA) cycle, DMAIC (Define-Measure-Analyze-Improve-Control) from Six Sigma, and Lean methods. Teams map processes, identify bottlenecks, perform root-cause analysis (eg, fishbone diagrams), and develop changes to address root causes. Data tools such as run charts and control charts help monitor performance and variation. Quality improvement emphasizes learning and adaptation, with cycles repeated to approach aims.

Fields of application: healthcare QI projects improve patient safety, clinical outcomes, patient experience, and operational efficiency; similar approaches are used in manufacturing, software, and services. Success depends on leadership support, multidisciplinary teams, frontline engagement, reliable measurement, and strategies for sustaining improvement.

Outcomes and challenges: QI can reduce errors, shorten wait times, lower costs, and improve staff morale, but results are highly context-specific. Common challenges include data quality, resource constraints, change fatigue, and difficulty disseminating successful changes beyond pilots.

Quality improvement differs from quality assurance, which focuses on meeting predefined standards and compliance, whereas QI emphasizes ongoing improvement and learning.
