Discrepancies of calculated percentage pain reduction versus patient reported percentage perceived reduction in pain intensity after axial spine medial branch block
The CCC ranged from 0.44 to 0.62 between PRPPR and CPPR in patients with chronic axial pain undergoing diagnostic MBB. PRPPR scores showed greater pain relief than CPPR scores, especially over time. Agreement was higher at extremes of pain relief, while partial average pain relief demonstrated less agreement. Clinicians should therefore not assume equivalence between CPPR and PRPPR. More importantly, there is significant variability in how a patient is categorized for MBB success depending on the measure employed.
