NHSA Module 9 Practice Test

Quality improvement is about ongoing, data-driven efforts to make processes better. Teams study how care is delivered, collect and analyze data, and run small tests to see what changes actually improve outcomes, then refine those changes in cycles. It’s a proactive, iterative process aimed at continuously reducing waste, errors, and delays and enhancing patient care.

Quality assurance, in contrast, is a set of activities designed to ensure that standards and requirements are being met. It involves checking, auditing, and monitoring to verify quality after work is done, often looking backward to confirm compliance with established guidelines or regulations.

So, the best way to understand the difference is: quality improvement actively seeks to improve how things are done using data and repeated testing, while quality assurance focuses on making sure those things meet predefined standards, typically in retrospective checks. For example, a QI effort might test a new flow to shorten appointment wait times and adjust based on results, whereas QA might audit chart documentation to ensure it meets regulatory documentation standards.
