Utilising sigmoid models to predict the spread of antimicrobial resistance at the country level

There is evidence that AMR spread tends to follow a sigmoid (logistic) shape i.e. an initial period of low-level resistance followed by a rapid increase in resistance and then a levelling-off at a level less than 100% resistance. Among 107 triads for which both sigmoid and linear models could be fit, the sigmoid model was a better fit in 84%. Researchers present a novel method of describing and predicting the spread of antibiotic-resistant organisms. Eurosurveillance
