Abstract

OBJECTIVE:

To establish the extent to which general practitioner age alone explains variations in patient morbidity and treatment patterns.

SETTING:

An on-going, national survey of general practice activity in Australia.

PARTICIPANTS:

A random sample of 5013 GPs with a minimum of 375 general practice Medicare items claimed in the previous 3 months. Each GP contributed details of 100 consecutive encounters, with about 1000 GPs sampled each year between 1998 and 2003.

MAIN OUTCOME MEASURES:

Effect of practitioner age on GP activity after removing the influence of measured confounding factors: doctor, patient and practice characteristics; number of problems; and morbidity managed at encounters.

RESULTS:

GP age played a significant role in practice style. In comparison with young GPs (< 35 years), older GPs provided more home visits (P < 0.001) and attendances at residential aged-care facilities (P = 0.044); were more likely to manage chronic problems (P < 0.001); had higher prescribing rates (P < 0.001), and lower rates of pathology ordering (P < 0.001) and non-pharmacological treatments (P < 0.001). Individual body system management rates also differed significantly between younger and older GPs.

CONCLUSION:

A GP's age plays a significant role in determining practice style. Our results have implications in terms of the ageing GP population and in the wider context of the ageing medical labour force.
