Health workers are making better use of AI than ever before. AI is poised to transform the healthcare sector through automation and deep learning. Already it is powering implants that monitor patients’ vital signs. Machine learning analyses of complex wound images mean that problems can be detected earlier, helping to prevent unnecessary procedures like diabetes-related amputations. Clinicians can flag injury patterns consistent with abuse. Deep learning tools can automate the process of quantifying pathogens in blood samples, helping to identify people who are unknowing vectors of infection, and tracing their movements through smartphones. And some ambulances will soon be self-driving, with inbuilt mechanisms that turn traffic lights green so they can zip patients off to hospital.
