Basic knowledge of drug resistance is widespread in Southeast Asia, but high level of awareness is linked to excess antibiotic use in the general population, reveals a new study led by Warwick University Assistant Professor Marco J Haenssgen, which is published in the medical journal BMJ Open.

The survey found that:
  • People's awareness of drug resistance was similar to that of many industrialised countries - three in four villagers in Thailand and six in ten in Laos had heard about "drug resistance," although the term was usually interpreted as a change in the human body rather than as the evolution of bacteria to withstand antibiotic medicine.

  • People's attitudes in rural Thailand and Laos were often consistent with recommendations from the World Health Organization to not buy antibiotics without prescription. However, such attitudes were linked to disproportionately and potentially problematically high rates of prescribed antibiotics from public clinics and hospitals - up to 0.5 additional antibiotic courses per illness on average when controlling for other drivers of antibiotic use.

  • People who obtained antibiotics from informal sources, such as the village shop, were just as aware of drug resistance as people who relied on public healthcare channels.

  • Patients receiving antibiotics from informal sources had no less wealth or formal education than users of public healthcare. Indeed, wealthier and more educated individuals in Chiang Rai were significantly associated with receiving antibiotics from informal sources, showing that it is not just people on low incomes who obtain antibiotics from informal sources.

    Project leader Asst Prof Marco J Haenssgen interprets these results as a sign that the conventional public health model of behaviour change is failing: "Too many arguments in public health behaviour change rest on a model of 'information deficits.' This idea that people behave irrationally because they don't have the right information finds little support in our research."

    "Basic awareness about drug resistance and antibiotics is widespread but does not contribute to better behaviour. New information can be empowering in principle, but people themselves decide how they will use this new 'power' in their daily lives. Unnecessary antibiotic use may then rather reflect privilege, resistance to patronising norms, or interference between local and Western ideas of what good care ought to be."

    Thailand and Laos were selected for this study because of their traditionally high rates of antibiotic use and busy international travel patterns, which predispose these countries to the development and spread of drug resistance. The survey involved 2,141 adults from more than 130 villages who represent a rural population of 712,000 villagers in Thailand and Laos. Dr Haenssgen argues that the findings have a wider relevance, however.

    "Ours is not an isolated case. Colleagues in China found for instance that more educated people were more likely to buy non-prescription medicine from unregistered stores, and the behavioural sciences have long established that information alone only accounts for a fraction of healthcare decisions. Public health has to catch up! To tackle the superbug crisis, we need to shift our attention to human decision-making processes and to people's behavioural responses to local contexts."
