Evaluation of the Better Access to Psychiatrists, Psychologists and GPs through the Medicare Benefits Schedule initiative: component B: an analysis of Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) administrative data

9.5 Does the relationship between Better Access uptake and demand for non-Better Access mental health MBS services at a divisional level differ between metropolitan and rural or remote regions?

Page last updated: August 2010

Analyses were then undertaken to examine whether the impact Better Access uptake on non–Better Access mental health MBS items differed between metropolitan and rural or remote areas. Figure 9.9 and figure 9.10 show the patterns of uptake of Better Access and non–Better Access MBS items across all metropolitan Divisions of General Practice.

Table 9.7 shows the summary statistics for non–Better Access mental health MBS items, separately for Divisions classified as metropolitan and rural or remote, and Better Access uptake in 2008.

Table 9.8 and table 9.9 present the results of the regression analyses for metropolitan regions. These show that metropolitan Divisions with relatively higher rates of persons using Better Access items also have relatively higher rates of persons using non–Better Access mental health MBS items (table 9.8). The same was true for the relationship between Better Access and non–Better Access services used (table 9.9).

Patterns in rural and remote regions were then considered. Figure 9.11 and figure 9.12 show the patterns of uptake of Better Access and non–Better Access MBS items across all rural and remote Divisions of General Practice.

Table 9.10 and table 9.11 present the results of the regression analyses for metropolitan regions. Almost identical results were found for rural and remote Divisions as for metropolitan Divisions. Rural and remote Divisions with relatively higher rates of persons using Better Access items also have relatively higher rates of persons using non–Better Access mental health MBS items (table 9.10). The same was true for the relationship between Better Access and non–Better Access services used (table 9.11).Top of page

Figure 9.9 consists of two graphs. The first graph shows persons using Better Access MBS items (rate per 1,000 population) for each of the metropolitan Divisions of General Practice, in ascending order. The usage ranges steadily from approximately 18 persons per 1,000 population at the low end to approximately 76 persons per 1,000 population at the high end.

The second graph shows persons using other mental health MBS items (rate per 1,000 population) for each of the metropolitan Divisions, in the same order as the first graph.

Comparing the two graphs shows that generally speaking, Divisions with a relatively higher rate of people using Better Access MBS items will tend to have a relatively higher rate of people using other mental health MBS items.

Figure 9.10 consists of two graphs. The first graph shows total Better Access services used (rate per 1,000 population) for each of the metropolitan Divisions of General Practice, in ascending order. The usage ranges fairly steadily from approximately 55 services used per 1,000 population at the low end to approximately 400 services per 1,000 population at the high end.

The second graph shows total other mental health MBS items used (rate per 1,000 population) for each of the metropolitan Divisions, in the same order as the first graph.

Comparing the two graphs shows that generally speaking, Divisions with a higher usage of Better Access services will tend to have higher usage of other mental health MBS items.

Figure 9.11 consists of two graphs. The first graph shows persons using Better Access MBS items (rate per 1,000 population) for each of the rural and remote Divisions of General Practice, in ascending order. The usage ranges steadily from approximately 12 persons per 1,000 population at the low end to approximately 64 persons per 1,000 population at the high end.

The second graph shows persons using other mental health MBS items (rate per 1,000 population) for each of the rural and remote Divisions, in the same order as the first graph.

Comparing the two graphs shows that generally speaking, Divisions with a relatively higher rate of people using Better Access MBS items will tend to have a relatively higher rate of people using other mental health MBS items.

Figure 9.12 consists of two graphs. The first graph shows total Better Access services used (rate per 1,000 population) for each of the rural and remote Divisions of General Practice, in ascending order. The usage ranges fairly steadily from approximately 24 services used per 1,000 population at the low end to approximately 248 services per 1,000 population at the high end.

The second graph shows total other mental health MBS items used (rate per 1,000 population) for each of the rural and remote Divisions, in the same order as the first graph.

Comparing the two graphs shows that generally speaking, Divisions with a higher usage of Better Access services will tend to have higher usage of other mental health MBS items.
