The Australian optometric workforce 2005, analysed by local government areas.

BACKGROUND

Previous studies of the Australian optometric workforce have taken a coarse view of the distribution of optometrists, at best comparing concentrations of optometrists in city and country areas and between states and territories. A more discriminating approach recognising the size and variation in population density of the country is necessary for a more realistic insight into the optometric workforce. This study addresses the distribution of optometrists across smaller geographic units, known as local government areas (LGAs).

METHODS

The number of equivalent full-time optometrists in each Australian LGA was determined using data from the Optometrists Association Australia database. Data from the Australian Bureau of Statistics and the Australian national health program (Medicare) were applied to determine the demand for services based on age distributions in LGAs and to calculate the adequacy of the number of optometrists.

RESULTS

Optometrists are concentrated in areas of high population with capital city regions and their surrounds well-serviced but with rural and remote LGAs with low populations generally not having optometrists. The highest excesses of optometrists occur in the capital city LGAs of Melbourne, Sydney and Adelaide (64, 60 and 28.4 equivalent full-time optometrists respectively). The highest deficits occur in Casey (Victoria), Lake Macquarie (New South Wales) and Onkaparinga (South Australia), (-16.4, -15.6 and -13.4 equivalent full-time optometrists, respectively).

CONCLUSIONS

There are substantial variations in the distribution of optometrists across LGAs in Australia but the variation is often a poor indicator of the ease with which people can access optometric services. In metropolitan areas, people may live close to an optometric practice in a neighbouring LGA. In rural areas, an LGA may appear to have an adequate number of optometrists but some residents may be several hours from the nearest optometrist or the optometric service is provided on a part-time basis.
