Antibiotics are our first line of defence against bacterial infections. Like all living things, bacteria evolve to survive. Some bacteria have evolved to resist antibiotics. Antibiotic resistant bacteria, or “superbugs” as they are sometimes known, pose one of the biggest threats to human health worldwide. If the rise and spread of superbugs continue at the current rate, common infections will become untreatable and medical procedures, such as minor surgery, will be unsafe. Experts believe that improving antibiotic prescribing practices and infection prevention and control techniques are critical in reducing the rise and spread of resistant bacteria, but more evidence is needed to best target efforts and resources in different settings.
Residential aged care plays an essential role in caring for older Australians. Aged care facilities support the health care, lifestyle and accommodation needs of older people who are unable to continue living independently in their own homes. While antibiotic resistant bacteria can be found everywhere, they are a concern within residential aged care facilities. Frailty and reduced immunity experienced by older people, coupled with high rates of antibiotic treatment and the potential for transfer between residents, are thought to all contribute to resistant bacteria.
The Generating evidence on Resistant bacteria in the Aged Care Environment (GRACE) study, aims to investigate the carriage and transfer of resistant bacteria or “superbugs” in residential aged care. The study is led by Professor Geraint Rogers from the South Australian Health and Medical Research Institute. Working in partnership with aged care providers the GRACE study will, for the first time, map the existence and spread of resistant bacteria in aged care. Funded by the National Health & Medical Research Council’s Medical Research Future Fund, this study will produce new evidence to help us to improve facility management, including cleaning and hygiene practices, to prevent the spread of harmful bacteria, and ultimately improve the health of aged care residents and the wider community. The GRACE study has been approved by the Southern Adelaide Clinical Human Research Ethics Committee.
The GRACE study will answer four important questions:
In partnership with Eldercare, Life Care, Resthaven and Helping Hand the study will take place across several aged care facilities in South Australia. All people living in these facilities will be invited to participate in the study. People who consent to participate in the GRACE study will be asked for a throat swab and a sample of their stool. This is so we can identify potentially harmful and resistant bacteria that might be harboured in the throat or the gut. The study will also collect information about participants’ medical history and healthcare needs. We will also take environmental swabs from participants’ rooms and common areas around the facility. The purpose of this is so we can identify potential sources and transmission routes of resistant bacteria.
Analysis of bacterial DNA from all samples collected will be carried out at the SAHMRI Microbiome laboratory at Flinders Medical Centre. Using a new method called metagenomic sequencing, we will be able to determine all bacteria that are present and whether they carry resistance genes. This is a novel approach to investigating resistant bacteria in an aged-care setting, which, combined with participant and environmental data, will allow us to better understand potential causes, sources and transmission routes of resistance.
