Australians confused about antibiotics

A new survey conducted by the National Prescribing Service has found that many Australians don't understand how antibiotics work, asking their doctors to prescribe antibiotics when they are not needed.

Four in five people expect a prescription for antibiotics from their doctor for ear, nose, throat or chest infections, and 51% of people said they would ask for one.

Confusion about antibiotics and the resultant misuse of these drugs contributes to the emergence and spread of superbugs – bacteria that are resistant to antibiotics. Half the survey respondents were unaware that bacteria can become resistant to antibiotics.

Furthermore, 40% did not know that unnecessary use of antibiotics contributes to resistance, and more than half of respondents were unaware that resistance increases when you don’t finish a whole course of antibiotics.

Dr Peter Taylor, the Assistant Director of Microbiology at Prince of Wales Hospital, explains that antibiotics don’t simply cause bacteria to become resistant, but also provide an advantageous environment for resistant bacteria to persist without having to compete with susceptible forms.

Some diseases are now at risk of being impossible to treat with current antibiotics die to resistant strains. “There are strains of multi-drug resistant tuberculosis in Africa, Asia and some European countries that are impossible to treat,” says Taylor.

“Some strains of bacteria that cause urinary tract infections are now resistant to both first and second-line antibiotics. This means effective treatment is delayed for up to 48 hours, increasing the mortality risk of people infected with these strains.

The development of new antibiotics to fight resistant strains is a costly and lengthy process, and no new classes of antibiotics will be delivered in the foreseeable future. Instead, researchers are trying to delay the emergence of new resistant strains by educating people to use antibiotics correctly.

“Education of health professionals as well as patients is crucial. Most resistant bacteria are transmitted from person to person, so reminders about personal and community hygiene are really important,” Taylor emphasises.
