Abstract
Background
Each year, the French independent bulletin Prescrire publishes a list
of medicines, 'Drugs to avoid', that should not be used in clinical
practice as their risk-to-benefit ratio is unfavourable. This study
assessed the market approval, reimbursement and use of these medicines in
Australia.
Methods
The approval status of the medicines included in 2019 Prescrire 'Drugs
to avoid' list was assessed by searching the Australian Register of
Therapeutic Goods website. Funding status was assessed on the
Pharmaceutical Benefits Scheme (PBS) website, the Australian public insurance system. Use levels were determined by examining governmental
reports on prescribing rates including the Australian Statistics on
Medicines (ASM) reports, drug use reports released by the Drug Utilisation
Sub Committee (DUSC) and PBS statistics.
Results
Of the 93 medicines included in the Prescrire 2019 'Drugs to avoid'list included, 57 (61%) were approved in Australia in 2019 including 9(16%) that were sold as over-the-counter medicines, 35 (38%) were listed on the PBS, 22 (24%) were registered but not listed on the PBS. Although most of these medicines were used infrequently, 16 (46%) had substantial use despite serious safety concerns. Dipeptidyl peptidase-4 (DPP-4) inhibitors were used by 22% of patients receiving a treatment for diabetes in 2016. More than 50,000 patients received an anti-dementia medicine in 2014, a 19% increase since 2009. Denosumab became the 8th medicine, in terms of total sales, funded by the Australian Government in 2017-2018.
Conclusions
Prescrire's assessments provide a reliable external benchmark to assess the current use of medicines in Australia. Sixteen 'drugs to avoid',judged to be more harmful than beneficial based on systematic, independent evidence reviews, are in substantial use in Australia. These results raise serious concerns about the awareness of Australian clinicians of medicine safety and efficacy. Medicines safety has become an Australian National Health Priority. Regulatory and reimbursement agencies should review the marketing and funding status of medicines which have not been shown to provide an efficacy and safety at least similar to alternative therapeutic options.
