CRPS and the Budapest Criteria: Getting the Diagnosis Right Matters
CRPS is already a life changing diagnosis. Getting it wrong makes things worse.
The original IASP criteria were very sensitive, they picked up almost everyone with CRPS, but they were not specific. Too many people with other neuropathic pain conditions were being labelled as CRPS, which meant confusion, wrong expectations and sometimes inappropriate procedures.
Harden and colleagues tested new diagnostic rules called the Budapest Criteria in people with confirmed CRPS and people with other limb neuropathic pain. The Budapest clinical criteria kept almost perfect sensitivity (0.99), but significantly improved specificity compared with the old IASP criteria. In simple terms, they were much better at separating “true CRPS” from “other nerve pain” while still missing almost no real cases.
At Pain Specialists Australia, we support using the Budapest Criteria, together with careful specialist assessment, to avoid both overdiagnosis and missed diagnosis. CRPS needs to be recognised early and correctly, so that people are offered the right mix of medical, interventional, physical and psychological care.
If you have ongoing limb pain after an injury or surgery, how confident are you that your diagnosis truly fits what you are living with?
