Objective: To determine the prevalence and associations of general practice registrars' performing absolute cardio-vascular risk (ACVR) assessment (ACVRa).
Design: A cross-sectional study employing data (2017-2018) from the Registrar Clinical Encounters in Training project, an ongoing inception cohort study of Australian GP registrars. The outcome measure was whether an ACVRa was performed. Analyses employed univariable and multivariable regression. Analysis was conducted for all patient problems/diagnoses, then for an 'at-risk' population (specific problems/diagnoses for which ACVRa is indicated).
Setting: Three GP regional training organisations (RTOs) across three Australian states.
Participants: GP registrars training within participating RTOs.
Results: 1003 registrars (response rate 96.8%) recorded details of 69 105 problems either with Aboriginal and/or Torres Strait patients aged 35 years and older or with non-Indigenous patients aged 45 years and older. Of these problems/diagnoses, 1721 (2.5% (95% CI 2.4% to 2.6%)) involved an ACVRa. An ACVRa was 'plausibly indicated' in 10 384 problems/diagnoses. Of these, 1228 (11.8% (95% CI 11.2% to 12.4%)) involved ACVRa. For 'all problems/diagnoses', on multivariable analysis female gender was associated with reduced odds of ACVRa (OR 0.61 (95% CI 0.54 to 0.68)). There was some evidence for Aboriginal and/or Torres Strait Islander people being more likely to receive ACVRa (OR 1.40 (95% CI 0.94 to 2.08), p=0.10). There were associations with variables related to continuity of care, with reduced odds of ACVRa: if the patient was new to the registrar (OR 0.65 (95% CI 0.57 to 0.75)), new to the practice (OR 0.24 (95% CI 0.15 to 0.38)) or the problem was new (OR 0.68 (95% CI 0.59 to 0.78)); and increased odds if personal follow-up was organised (OR 1.43 (95% CI 1.24 to 1.66)). For 'ACVRa indicated' problems/diagnoses, findings were similar to those for 'all problems/diagnoses'. Association with Aboriginal and/or Torres Strait Islander status, however, was significant at p<0.05 (OR 1.60 (95% CI 1.04 to 2.46)) and association with female gender was attenuated (OR 0.88 (95% CI 0.77 to 1.01)).
Conclusion: Continuity of care is associated with registrars assessing ACVR, reinforcing the importance of care continuity in general practice. Registrars' assessment of an individual patient's ACVR is targeted to patients with individual risk factors, but this may entail ACVRa underutilisation in female patients and younger age groups.
