Patient's Attitude Predicts Time to Joint Arthroplasty
Willingness to consider total joint arthroplasty is strongest predictor of time to first surgery
MONDAY, Oct. 2 (HealthDay News) -- A patient's willingness to consider total joint arthroplasty for treatment of osteoarthritis is the strongest predictor of the time to first procedure, according to a report in the October issue of Arthritis & Rheumatism.
Gillian A. Hawker, M.D., from the University of Toronto in Ontario, Canada, and colleagues conducted a prospective cohort study of 2,128 individuals with disabling hip and/or knee arthritis to understand the factors that affect the time to first total joint arthroplasty (TJA).
Patients willing to consider TJA at the baseline visit had a greater probability of undergoing the procedure compared with those who did not (hazard ratio, 4.92). Other strong predictors to first procedure were age and higher baseline osteoarthritis index scores. When willingness to consider TJA was dropped from the model, the patient's education level become a prime determinant of time to first TJA.
"Given that previous research indicates that willingness is largely explained by perceptions of the indications for and risks associated with TJA, and not disease severity, this finding supports the need for population education about arthritis treatments, including TJA," the authors conclude.
