Among patients with advanced osteoarthritis, socioeconomic status influenced patient knowledge of their medical condition, decision status and treatment decision, with use of shared decision-making tools benefiting patients of all types of backgrounds, according to study results.

Researchers randomly assigned 123 patients with hip and knee osteoarthritis to a shared decision-making (SDM) intervention group or a control group. Patients in the intervention group received a booklet and DVD decision aids that provided evidence-based, unbiased information on both surgical and non-surgical treatment options and supported a more informed dialog between individuals and physicians. These patients were asked to write down a list of questions they may want to ask the doctor during consultation.

Patients in the control group received a standardized two-page brochure about osteoarthritis sent to all patients. Both groups completed a baseline survey that included questions on knowledge related to osteoarthritis, education level and income level.

Compared with patients with Medicare, results showed patients with private insurance were 2.7-times more likely to arrive at a treatment decision during the initial visit. The researchers also found a stronger association when accounting for age, gender and ethnicity.

Patients with a higher education level had lower odds of choosing surgery vs. non-operative treatment, and use of SDM tools had no significant effect on the likelihood of choosing surgical vs. non-surgical treatment, according to the researchers. – by Casey Tingle
