SYDNEY, August 2 AAP - Doctors around the world have breached their duty of care by misusing antibiotics, says an Australian infectious diseases expert.
The way in which bugs have become resistant to antibiotics within two generations of their discovery is one of the great tragedies of human history, says Dr Krispin Hajkowicz, an infectious diseases physician and a senior lecturer at the University of Queensland.
"My view is yes doctors are to blame," he has told colleagues at a Gold Coast conference hosted by the Australasian Society for Infectious Diseases (ASID).
"The people of the world want to hold someone accountable. Using the approach of a medical litigation claim, it can be shown that the current crisis was largely foreseeable, that doctors had a duty of care to preserve the precious resource of effective antimicrobials and that they breached this duty of care," says Dr Hajkowicz.
He points to evidence from studies showing up to half of all antibiotic prescriptions are inappropriate. At the same time attempts to improve standards are failing.
He says national guidelines enforced by law are necessary to bring public and private doctors into line.
"Additionally, doctors must promote the development of novel antimicrobials and then use these responsibly. Perhaps a new generation of doctors will undo what we have so foolishly done."
Another delegate , Joshua Freeman of the Auckland District Health Board, says international air travel is providing an unprecedented opportunity for the transfer of drug-resistant bugs.
"Travel to high-prevalence countries and, in particular, hospitalisation within those countries should be viewed as an important risk factor.
Dr David Grolman of Pfizer Australia & New Zealand says antibiotics have been a major contributor to improved life expectancy.
"It is not the development of the drugs per se that has resulted in accelerating the rate of bacterial antibiotic resistance, but the inappropriate and excessive usage of the drugs."
He says: "We need a concerted effort by all players in healthcare and governments to develop new antibiotics."
