Objective: To document the management of foot/ankle osteoarthritis/arthritis (OA) by general practitioners (GP) in Australia.
Design: We analysed data from the Bettering the Evaluation and Care of Health Program April 2010-March 2016 inclusive. Patient and GP encounter characteristics were extracted. Data were classified by the International Classification of Primary Care, Version 2, and summarised using descriptive statistics and 95% confidence intervals (95% CIs) around point estimates.
Results: The dataset included 583,900 patient-encounter records among which foot/ankle OA was managed 621 times, at a rate of 1.1 per 1000 encounters, with an annual estimated 152,000 GP encounters nationally. The management rate was most frequent among patients aged 65-74 years (2.25 per 1000 encounters). Comorbidities were managed at a rate of 105.8 per 100 encounters, the most common being hypertension, and few being other musculoskeletal problems. Foot/ankle OA was mostly managed using medication (64.6 per 100 problems), with prescription rates far exceeding non-pharmacological strategies such as counselling, advice or education (17.7 per 100), or allied health referral (10.1 per 100). When considering specific health/medical professionals, patients were referred to orthopaedic surgeons 8.4 times per 100 foot/ankle problems, podiatrists 6.3 times per 100 foot/ankle problems, and physiotherapists 2.6 times per 100 foot/ankle problems.
Conclusions: Pharmacological management rates of foot/ankle OA were high and substantially exceeded non-pharmacological management such as lifestyle advice and allied health referral. Longitudinal studies are needed to determine the effectiveness of this care compared to self-management and conservative non-drug treatment in people with foot/ankle OA.
