APEx Self-Assessment
APEx is Designed for Excellence
When asking about APEx, a common question from radiation oncology practices is, what’s the difference between APEx and other radiation oncology accreditation programs?
There are a few differences, but the most important one is APEx’s unique focus on practice improvement through its structured Self-Assessment.
Why the Self-Assessment Matters
APEx Self-Assessment Drives Improvement before the Facility Visit
While other programs provide broad or modality-focused accreditation, APEx is tailored to modern radiation oncology practices. Its strength lies in supporting teamwork and ensuring patient-centered care through an objective self-evaluation.
Built on the PDSA methodology (Plan, Do, Study, Act) the APEx Self-Assessment is a systematic approach for radiation oncology staff to evaluate their processes, implement changes, measure results and refine workflows for sustained excellence before the APEx Surveyors even begin their review.
