Every year hundreds of thousands of people die because of infections that have become resistant to treatment. A new data-mining, clinical monitoring and decision-support system, developed by EU-funded researchers, offers a powerful new weapon in the war on resistance to antibiotics. According to the World Health Organisation, around 440,000 new cases of multidrug-resistant tuberculosis emerge annually, causing at least 150,000 deaths. The DebugIT project developed a system to monitor antimicrobial resistance using data from different hospitals, identify trends showing which types of bacteria are becoming resistant to certain types of antibiotics, and then use that knowledge to implement courses of treatment with more effective drugs.
