PsA scoring systems showed moderate sensitivity, high specificity in detecting change

November 3, 2017

The quantifying of radiographic axial psoriatic arthritis through currently available scoring systems has moderate sensitivity but high specificity for identifying true change, according to results.

Researchers obtained radiographs of 105 patients with axial PsA from the University of Toronto PsA clinic. Patients had serial radiographs, separated by at least 2 years, and obtained since 2003. Researchers extracted two sets of axial radiographs. Three radiologists blinded to name and order of examination scored the radiographs using the scoring model of axial radiograph Toronto (SMART) application. Using the application, they automatically calculated Bath ankylosing spondylitis radiology index for the spine (BASRI-s), the modified stroke ankylosing spondylitis spine score (mSASSS), the radiographic ankylosing spondylitis spine score (RASSS) and PsA spondylitis radiology index (PASRI) scores. The existence of true radiographic progression was determined by an independent expert who viewed the radiographs with knowledge of the chronology. Researchers identified true change by determining the sensitivity, specific and odds ratios for every 1-unit increase in scores.
