Health assessments/health checks are the second most frequent reason for encounter in Australian general practice (after prescription requests), occurring at a rate of 8.6 per 100 encounters. Health assessments, comprising preventive health activities and screening, are core elements of comprehensive general practice. They are particularly important in addressing the health disparities faced by disadvantaged population groups, like Aboriginal and Torres Strait Islander people. For many GP registrars, undertaking preventive health assessments and population screening will require the application of new knowledge and skills.
