From: Canadian physiotherapists' views on certification, specialisation, extended role practice, and entry-level training in rheumatology

Variable Odds Ratio (95% CI)
Predicting interest in being a Certified Arthritis Therapist (Max-rescaled R2 = 0.19, c = 0.73)
Current arthritis caseload  
   ≥ 40% of patients with OA or RA 2.24 (1.17, 4.28)
   <40% of patients with OA or RA 1.00
"All patients referred to see an orthopaedic surgeon for consultation should be first triaged by a PT with advanced arthritis training"  
   Strongly agree/agree 3.24 (1.31, 8.01)
   Not sure 2.53 (0.99, 6.49)
   Disagree/strongly disagree 1.00
"All PTs working in rheumatology should be certified as Arthritis/Rheumatology Therapists"  
   Strongly agree/agree 2.22 (1.10, 4.51)
   Not sure 1.47 (0.65, 3.31)
   Disagree/strongly disagree 1.00
"I see no difference between "certification" and "specialisation" in physiotherapy"  
   Strongly agree/agree 0.34 (0.14, 0.83)
   Not sure 0.41 (0.16, 1.02)
   Disagree/strongly disagree 1.00
Predicting interest in being a PT specializing in rheumatology (Max-rescaled R2 = 0.14, c = 0.70)

"In Canada, less than 20% of PTs in arthritis rehabilitation will be interested in being a specialist"
