Policies designed to ensure Indigenous Australians have to medicines aren’t being accessed uniformly across the nation, shows.

We mapped where Indigenous Australians are using a program to access free or discounted medicines under the Pharmaceutical Benefits Scheme (PBS). We found access was patchy and depended on where you live.

This is particularly concerning as many Indigenous Australians in areas with of chronic conditions are not using the program.

Here’s what could explain our findings and what needs to happen next.

What are ‘Closing the Gap’ scripts?

In 2010, the Australian government introduced the (colloquially known as CTG scripts).

This program continues today and means Indigenous Australians:

• who would otherwise pay A$31.60 for a script, pay the concessional rate instead ($7.70)

• who would otherwise pay the concessional rate ($7.70) get their scripts for free.

The program was initially aimed at people with chronic disease. However, the program was in 2021 to increase access.

Now, Indigenous Australians can qualify regardless of age, chronic disease status, and provider location. Changes now mean all PBS prescribers and Aboriginal and Torres Strait Islander Health Practitioners can register patients. Registration is now one-off and lasts for a patient’s lifetime.

Initial research shows this program went some way to reduce in access to health care. After it was introduced, Indigenous Australians prescription medicines and chronic disease services, and made more GP visits.

Other studies also suggest areas with higher uptake of the program had hospitalisations for chronic conditions.

But uptake is patchy

Despite these benefits, our shows uptake varied dramatically depending on where Indigenous Australians live.

We used census-linked data to estimate regional differences in the proportion of Indigenous patients who had ever received a CTG script between 2011 and 2020.

In parts of northern Australia less than 30% of the Indigenous population had ever received a CTG script. In Tasmania this was around 30-40%. This was ten years after the policy was introduced.

Uptake in other states, such as Victoria and New South Wales, varied considerably, ranging from 15% to 87%.

Why the regional differences?

There appear to be multiple and potentially interacting factors influencing uptake of the scheme.

1. Higher rates of chronic conditions in some areas

In some rural and remote areas – particularly in NSW, South Australia, and Victoria – higher uptake could be explained by of chronic conditions among Indigenous populations. People with chronic conditions are more likely to need ongoing scripts.

However, we don’t see this pattern in remote parts of Western Australia, the Northern Territory, Australian Capital Territory, Queensland and Tasmania, where we also see of chronic conditions.

2. People may already be accessing other medicine subsidy programs

Broadly, Indigenous populations in remote areas are less likely to access CTG scripts. That’s because they can receive free prescription medicines through the . So, for many Indigenous Australians in these regions there may be little perceived benefit to registering for CTG scripts.

However, this is not the case for Tasmania and Victoria where there is to this alternative program.

The rates of uptake of CTG scripts in Tasmania and the ACT were among the lowest in the country. However, the Indigenous populations in these regions have some of the in the country. So other factors must be at play.

3. Red tape, not all health services on board

We also need to look at what’s happening in primary health care. Not all Indigenous patients are accurately identified. This could be because patients and don’t tell health services or because . Smaller practices with and those in more remote areas were also in the program.

Until 2021, when access to the program widened, fewer providers were eligible to register Indigenous patients to receive CTG scripts. This may have also .

So this and overall program complexity appears to have hindered Indigenous people from accessing the program.

How could we improve access?

1. Support Indigenous patients to feel safe

Many researchers and community leaders have written about the need to provide , necessary safe, accessible and responsive health care free of racism.

Providing can make Indigenous people more likely to identify. This , so patients can access relevant and appropriate health services, such as CTG scripts, to improve health.

2. Engage communities

The regional variation of CTG uptake suggests community-level are needed. Policymakers could consider additional targeting of resources based on location and community-specific factors. This might mean administrative or program support to deliver these initiatives, including via Aboriginal Health Services and better use of the . We know these community programs have and .

3. We need a data strategy

There is minimal analyses on CTG uptake and impacts since 2020. But this isn’t the only data gap, nor are all data about Indigenous Australians’ use of medicines linked.

For instance, the Australian Institute of Health and Welfare no longer reports data on Indigenous people’s ; there is still to capture remote medicines use; and minimal Indigenous data is reported for relevant , to name a few.

As outlined in the , Indigenous Australians are the key stakeholders of the data discussed here. This means Indigenous Australians must “own” the data, and govern how it’s collected and used. Any program or policies involving that data must also be co-designed with Indigenous Australians.

Such principles are fundamental to ensure further evaluation and ongoing roll-out of programs, such as CTG scripts, are equitable and effective for Indigenous Australians.
