A new national audit led by Monash University has shed light on how medication use is governed in Australian residential aged care, revealing wide variation in the structure and function of Medication Advisory Committees (MACs) across the country.
MACs are central to promoting medication safety in residential aged care, with their presence identified as a key intervention to managing the issue of polypharmacy – the use of nine or more medications simultaneously.
A MAC is a ‘multidisciplinary committee that provides overarching governance of medication management within residential care homes’. The Australian Government Department of Health, Disability and Ageing recommends that all residential care homes have access to a MAC to support safe use of medications and, ultimately, mitigate risks associated with inappropriate prescribing.
Researchers from the Centre for Medicine Use and Safety (CMUS), within the Monash Institute of Pharmaceutical Sciences (MIPS), led the national audit to examine how MACs function across their four recommended operational domains; policy development, risk management, education, and quality improvement.
The audit, adapted from the Department of Health and Aged Care’s MAC Audit Tool, involved 120 MACs overseeing 642 residential care homes – almost a quarter of all Australian residential care homes.
The findings show that MACs are actively involved in policy and risk oversight – with 59 and 53 per cent respectively performing all recommended functions – with further opportunities for capacity building and long-term improvement. Overall, 41 per cent fulfilled all educational roles, and 28 per cent were fully engaged in quality improvement initiatives.
The study’s lead author, CMUS research fellow Dr Amanda Cross, said “this audit highlights both the strengths and the areas needing targeted support in how we manage and govern medication safety in aged care. MACs have the potential to lead transformational change in this sector – if adequately supported and resourced.”
With the new strengthened Aged Care Quality Standards due to commence on 1 July 2025, Dr Cross says “MACs are well positioned to support implementation and monitoring of Quality Standard 5 to ensure delivery of safe and quality clinical care to the almost 200,000 older Australians who access residential care.”
The study forms part of a larger program of work funded by the Medical Research Future Fund. Professor Simon Bell, project lead of the Maximising Embedded Pharmacists in aGed cAre Medication Advisory Committees (MEGA-MAC) project, said that “the national quality improvement collaborative implemented as part of the MEGA-MAC project utilises a real-time clinical network designed to deliver, monitor and evaluate quality improvement initiatives.”
