Adequacy of Australia's GP workforce: estimating supply and demand, 2005-06 to 2015-16

Objective A 2011 Australian study calculated average annual general practitioner (GP) utilisation and predicted numbers required to meet demand to 2020. The objective of the present study is to calculate average annual GP utilisation in 2015-16 compared with clinical demand predicted in 2005-06. Methods Demand was calculated from Medicare Benefits Schedule, Department of Veterans' Affairs and Australian Bureau of Statistics data. Length of consultation and average clinical hours worked per week (from 2002-03 to 2015-16) was drawn from GP self-reported data collected through the Bettering the Evaluation And Care of Health (BEACH) program. GP workforce numbers were sourced from the Australian Institute of Health and Welfare 'Medical practitioners workforce 2015' report. Results Predicted demand from 2005-06 to 2009-10 approximated GP supply. Beyond 2011, approximately 2674 additional GPs were required in 2015-16 to maintain the average annual 2005-06 GP workload. An additional 5941 GPs were required to meet the increase in clinical demand (for GP services to patients) from 2005-06 to 2015-16. Conclusions The number of GP clinical hours worked decreased, and clinical demand increased. Ongoing efforts are required to ensure the supply of GPs to meet the clinical demand of Australia's aging population. What is known about this topic? For the past three decades there has been concern about the supply of GPs in Australia. In recent years the Australian Government has taken several steps to improve access to GP services by increasing the overall supply of GPs and encouraging a more even distribution of GPs across Australia. A 2011 Australian study calculated average annual GP service utilisation and predicted the number of GPs required to meet clinical demand to 2020. There are current concerns that the GP workforce has reached a state of oversupply. What does this paper add? This study concludes that the GP workforce is not in a state of oversupply, confirming that patient clinical demand increased through both population growth and the aging of the population. Although the number of GPs increased, the number of clinical hours worked by (male) GPs decreased. Therefore, the rise in the number of GPs did not result in a proportional rise in GP workforce capacity. Clearly standardised definitions and inclusions for counting the GP workforce would improve accuracy in measuring this section of the health workforce. What are the implications for practitioners? GP workforce supply will require ongoing monitoring over coming years considering the increasing population, the aging of the population, declining clinical GP working hours and the approaching mass retirement of older GPs.
