Performance improvement (PI) is the continuous study and improvement of processes with the intent to better services or outcomes, and prevent or decrease the likelihood of problems, by identifying areas of opportunity and testing new approaches to fix underlying causes of persistent/systemic problems or barriers to improvement1.

PI is based on the assumption that most problems are related to the processes rather than the people who perform them2. Therefore, studying and understanding the processes that deliver the services or outcomes is essential to identify the root causes of problems, the gaps between current and desired performance, and the potential solutions to improve them34.

PI uses various methods and tools to analyze and measure processes, such as flowcharts, process maps, cause-and-effect diagrams, Pareto charts, histograms, control charts, run charts, and scatter diagrams5. These tools help to visualize the steps, inputs, outputs, and variations of a process, and to monitor and evaluate its performance over time6.

PI also uses various models and frameworks to guide and accelerate improvement work, such as the Model for Improvement, Plan-Do-Study-Act (PDSA) cycles, Lean, Six Sigma, and Total QualityManagement (TQM)7. These models and frameworks help to define the aim, the measures, and the changes for improvement, and to test and implement them in a systematic and iterative way8.

Therefore, in order to make effective long-term changes, PI emphasizes the need to study and understand the processes that produce the services or outcomes, as this will help to identify and address the sources of variation, waste, and inefficiency, and to achieve better quality, safety, equity, value, and system sustainability9 . References: 1: QAPI Description and Background | CMS 2: Basics of Quality Improvement | AAFP 3: How to Improve: Model for Improvement | Institute for Healthcare Improvement 4: Performance Management and Quality Improvement - CDC 5: [Tools for Quality Improvement | NAHQ] 6: [Quality Improvement Tools and Methods | Agency for Healthcare Research and Quality] 7: [Quality Improvement Models and Frameworks | NAHQ] 8: [Quality Improvement Essentials Toolkit | Institute for Healthcare Improvement] 9: [Healthcare Quality and Safety Workforce Report: New Imperatives for Quality and Safety Mean New Imperatives for Workforce Development | NAHQ] : [The Financial Case for Quality as a Business Strategy | NAHQ] : [Tools for Quality Improvement | NAHQ] : [Quality Improvement Tools and Methods | Agency for Healthcare Research and Quality] : [Quality Improvement Models and Frameworks | NAHQ] : [Quality Improvement Essentials Toolkit | Institute for Healthcare Improvement] : [Healthcare Quality and Safety Workforce Report: New Imperatives for Quality and Safety Mean New Imperatives for Workforce Development | NAHQ] : [The Financial Case for Quality as a Business Strategy | NAHQ] : Tools for Quality Improvement | NAHQ : Quality Improvement Tools and Methods | Agency for Healthcare Research and Quality
