What is Performance and Process Improvement?
Performance and Process Improvement is the largest domain on the CPHQ exam at nearly 22% of all questions. This domain covers the methodologies, tools, and techniques used to improve healthcare processes and outcomes. You must understand the full spectrum of quality improvement approaches, from Plan-Do-Study-Act (PDSA) cycles to Lean methodology to Six Sigma DMAIC. This domain tests your ability to select the right improvement tool for a given situation and to measure whether an improvement actually worked.
Key Concepts to Master
Master the quality improvement tools: flowcharts, cause-and-effect (fishbone) diagrams, Pareto charts, run charts, control charts, scatter diagrams, histograms, and check sheets. Understand statistical process control (SPC) and the difference between common cause and special cause variation. Know how to calculate and interpret basic statistics including mean, median, mode, standard deviation, and percentiles. Study benchmarking types (internal, competitive, functional, generic) and how to use benchmarking data to drive improvement. Understand PDSA vs PDCA and when to use each approach.
Study Tips for This Domain
Since this is the highest-weighted domain, dedicate proportionally more study time here. Practice reading control charts - know the rules for detecting special cause variation (Western Electric rules, Nelson rules). Work through sample PDSA cycles from start to finish. Understand the Lean concepts of value stream mapping, waste elimination (the 8 wastes), 5S, and kaizen events. For Six Sigma, focus on DMAIC phases and key tools used in each phase. Do not just memorize definitions - practice applying these tools to healthcare scenarios.
Frequently Asked Questions
- How many questions are in the PI domain?
- Approximately 22-27 questions (21.6% of the exam) focus on Performance and Process Improvement, making it the largest domain.
- Do I need to know Six Sigma statistics?
- You should understand basic statistical concepts and control chart interpretation. You do not need to perform complex calculations, but you should know what sigma levels mean and how to interpret p-values.
- What is the difference between PDSA and PDCA?
- PDSA (Plan-Do-Study-Act) emphasizes learning and studying results before acting. PDCA (Plan-Do-Check-Act) focuses on checking conformance. PDSA is generally preferred in healthcare quality improvement.
