Doctors 'nudged' into prescribing far fewer antibiotics

Medicimage/REX/Shutterstock By New Scientist staff and Press Association Family doctors in the UK have been nudged into handing out tens of thousands fewer prescriptions for antibiotics. The over-use of antibiotics is driving the spread of antimicrobial resistance worldwide, a crisis that is expected to cause 10 million deaths a year by 2050. One approach for slowing the spread of antibiotic resistance is to cut down on the unnecessary use of these drugs – such as for conditions like colds and other viral infections. A 2015 study found that 40 million antibiotic prescriptions were given in the UK the preceding year, of which 10 million were unnecessary. But it can be difficult for family doctors to refuse antibiotics. "Patients are aware of the issue but they sometimes come in geared up for battle," GP Maureen Baker told New Scientist earlier this year. Now the Behavioural Insights Team say they have found a way to encourage GPs to reduce the amount of antibiotics they prescribe. Formerly known as the UK government's "nudge" unit, the now private organisation attempts to understand human behavior and use it to subtly push for positive changes. Between 2014 and 2015, the Behavioural Insights Team sent letters to 800 GP practices, telling them that other practices were recommending the use of antibiotics in fewer cases. The organisation claims this message reduced the number of antibiotic prescriptions by 73,406 – just over 3 per cent. This finding may prove particularly useful if applied to certain areas of the UK. A mapping project last year found that GP practices in some areas of England prescribe far more antibiotics than doctors in other parts of the country. Targeting these hotspots could be an important step in combating antibiotic overuse. However, the fact that these places tend to be some of the most deprived areas of the country hints there may be underlying socioeconomic factors at play that cannot be solved with a subtle nudge.
