Study highlights reasons behind antibiotic use in children in rural and remote NT

Northern Territory mothers living in remote or rural areas often make decisions about the need for antibiotics for their children out of fear or based on the advice of their personal network a new study by Charles Darwin University (CDU) researchers has found.

Lead author and CDU PhD student Stephanie Marsh has explored the factors that contribute to a parent’s decision to give their children antibiotics to learn more about overuse and misuse of antibiotics, a key driver for the acceleration of antimicrobial resistance (AMR).

AMR, which is when microorganisms such as bacteria and fungi defeat the drugs designed to kill them, is fast becoming an urgent global health threat.

Ms Marsh said as children are amongst the highest recipients of antibiotics, there is a great need for understanding the drivers of parental decisions towards their children’s antibiotic use.

“There is limited information around antibiotic use and the reasons behind it in rural and remote areas in the NT,” Ms Marsh said.

“We need to learn about and understand these behaviours, including those that are less optimal to help find ways to combat AMR.”

For the study, Ms Marsh conducted focus groups with mothers in rural and remote communities across the Territory.

A significant finding from the study revealed that decisions about the use of antibiotics were not always knowledge-based and were often driven by fear of serious illness.

“The mothers we spoke with displayed some accurate knowledge that antibiotics treat bacterial infections, which contributed to their general understanding of the role of antibiotic medicines,” Ms Marsh said.

“However, decisions about the use of antibiotics were not always based on knowledge with parental beliefs also guiding opinions and behaviour.”

When making health decisions about the use of antibiotics, participants in the study indicated that they often obtained guidance from others.

“The mothers reported that despite favouring the doctor’s advice when deciding on antibiotic treatment for their child, they also highly valued input from others in their social network, such as friends and family,” Ms Marsh said.

“Whilst they may obtain this advice differently and for varying reasons, nearly all parents reported to seek additional direction from others to alleviate their concerns.”

Interestingly, the study found that mothers are more cautious in their approach towards antibiotics use in infants.

“We saw differences in the findings between first-time mothers of a child less than 12 months of age and mothers with more than one child,” Ms Marsh said.

“First-time mothers with babies had the most optimal behaviours with antibiotics, this was likely due to these parents having less exposure to using antibiotics and managing childhood illnesses than parents with older and multiple children.”

Access to healthcare also played a significant role in the mother’s decisions to utilise antibiotics with nearly all mothers raising difficulties with their children being seen by a GP in a timely manner.

Ms Marsh’s supervisor Professor Mitchell Byrne said the findings from this research would help inform interventions to reduce the impact of AMR.

“From this study, we now understand the drivers behind parental decisions to give their children antibiotics in rural and remote areas which will help us to formulate a range of primarily educational-based interventions,”

The project team which includes CDU Lecturer in Psychology Dr Sara Parsafar, who is co-supervisor, will now look to commence a systemic review of parental decisions regarding antibiotic use in children across the world to assist with the development of interventions.
