14 November: Paracetamol overdoses | Health literacy is a societal responsibility | Can spine stimulators treat back pain?

There's been talk of changing the packet size of paracetamol tablets, to reduce the self-harm of overdose—but it would be better to investigate and remedy why this harm occurs.The idea that society—as well as an individual—is responsible for this 'health literacy' is central to a new World Health Organisation report.Results of a randomised trial in people with low back pain who used a spinal cord stimulator were published recently, and the researchers are surprised by what they found.Hosts: Dr Norman Swan and Tegan Taylor
