Description
Summary:Summary Objective The purpose of this study is to examine the perceptions of primary care physicians (PCPs) regarding indications, contraindications, risks and benefits of total joint arthroplasty (TJA) and their confidence in selecting patients for referral for TJA. Design PCPs recruited from among those providing care to participants in an established community cohort with hip or knee osteoarthritis (OA). Self-completed questionnaires were used to collect demographic and practice characteristics and perceptions about TJA. Confidence in referring appropriate patients for TJA was measured on a scale from 1 to 10; respondents scoring in the lowest tertile were considered to have ‘low confidence’. Descriptive analyses were conducted and multiple logistic regression was used to determine key predictors of low confidence. Results 212 PCPs participated (58% response rate) (65% aged 50+ years, 45% female, 77% >15 years of practice). Perceptions about TJA were highly variable but on average, PCPs perceived that a typical surgical candidate would have moderate pain and disability, identified few absolute contraindications to TJA, and overestimated both the effectiveness and risks of TJA. On average, PCPs indicated moderate confidence in deciding who to refer. Independent predictors of low confidence were female physicians (OR = 2.18, 95% confidence interval (CI): 1.06–4.46) and reporting a ‘lack of clarity about surgical indications’ (OR = 3.54, 95% CI: 1.87–6.66). Conclusions Variability in perceptions and lack of clarity about surgical indications underscore the need for decision support tools to inform PCP – patient decision making regarding referral for TJA.
