Objective: To examine 25(OH)D testing patterns and frequency among general practitioners in a major community health service. Method: A clinical audit of patient records at a community health centre in Melbourne was undertaken. Patients aged 18 years and above were included. Univariate and multivariate logistic regression was used to examine the association between vitamin D testing and socio‐demographic characteristics while Poisson regression was used for the frequency of testing. Results: There were 1,217 patients tested for serum 25(OH)D. The community health centre was served by 12 general practitioners and an infectious disease specialist. The odds of vitamin D testing showed a positive, albeit weak, association with age (OR 1.01, 95%CI 1.00–1.02, p <0.05), were higher among females than males (OR 1.42, 95%CI 1.18–1.70, p <0.05) and higher among migrants compared to non‐migrants (OR 2.57, 95%CI 2.14–3.09, p <0.05). The frequency of testing was also higher among females than males (IRR 1.17, 95%CI 1.07–1.28, p <0.05) and higher among migrants than non‐migrants (IRR 1.19, 95%CI 1.08–1.31, p <0.05). Conclusion: Advancing age, being female and being a migrant were associated with an increased likelihood of vitamin D testing. Implications: Development of evidence‐based policies and guidelines are needed to manage over‐testing of vitamin D in Australia. Studies that include health services from different areas are required to understand vitamin D testing patterns among the general practitioners.
