Georgina Hughes is a pharmacist & PhD Candidate with the University of South Australia Clinical and Health Sciences and the Registry of Senior Australians (ROSA), undertaking research at South Australian Health and Medical Research Institute (SAHMRI).
Georgina’s PhD study and first published paper was on how to improve the safe and effective use of antidepressant medicines and optimise quality use of medicines in older people accessing residential aged care.
The study, published in the Journal of American Medical Directors Association (JAMDA), was led by Georgina, in collaboration with Professor Maria Inacio and Associate Professor Janet Sluggett. It’s Australia’s first national study investigating the use of antidepressants among older people living in residential aged care homes across the country, analysing the de-identified data of 779,659 residents from 3,371 aged care homes, between 2006 and 2019.
“We found antidepressants were used by 46.1% of residents in 2006 and this increased to 58.5% of residents in 2019,” Ms Hughes said.
“Nearly six in every ten residents of aged care homes are using an antidepressant, which is much higher than use in the general older population.”
The use of antidepressant medicines among older people in aged care homes in Australia is high, and there is a need for better mental health support and safer use of antidepressants to improve clinical care and health outcomes for older people.
Antidepressant medicines can have side effects, especially in older people, and Australia is one of the largest consumers globally.
Almost 60% of aged care home residents are using antidepressant medicines, prompting the need to investigate the reasons for such high usage.
Georgina talks to how big data is crucial in understanding and improving the use of antidepressant medicines in aged care, leading to better clinical care and health outcomes for older people in Australia.
Georgina is passionate about practice-informing, translational and innovative research to improve quality use of medicines and health outcomes.

CASE STUDY Link between levels of extracellular vesicles in the blood and tissue damage caused by diseases
A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.
This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia.
Researchers hope to leverage the critical new insight to develop a blood test to monitor cancer patients with tissue damage, which could, in future, enhance treatment strategies for blood cancers and other diseases.

Food and fasting periods as medicine to prevent disease
Professor Leonie Heilbronn is based at the South Australian Health and Medical Research Institute (SAHMRI), where she leads the Obesity and Metabolism laboratory. Her research is at the interface between basic and clinical science. She is internationally recognised for her work in nutritional modulation in humans and has made major contributions to our current understanding of mechanisms underlying conditions such as insulin resistance, particularly inflammation and lipid metabolism. She has also contributed significantly to current concepts of caloric restriction (CR), intermittent fasting (IF) and time restricted eating (TRE) in humans. She has published more than 110 peer reviewed papers in scientific journals and is an Associate Editor of Obesity, and Obesity Research and Clinical Practice.

Identifying and treating autoimmune neurological disorders
Associate Professor Sudarshini Ramanathan is a neurologist and clinician scientist whose work focuses on autoimmune neurological disorders. Her research has helped identify new neurological syndromes due to antibody-mediated demyelination and encephalitis, and improve diagnostic tools and treatment guidelines for patients with autoimmune diseases affecting the brain, spinal cord, muscles and nerves.
