In this episode of the BMJ's Medicine and Science podcast, editor-in-chief Kamran Abbasi discusses the urgent need to tackle disinformation in health, especially in the context of the US, with Heidi Larson and Martin McKee from the London School of Hygiene and Tropical Medicine.    We also hear from Jane Ballentyne, professor of anaesthesia and pain medicine at the University of Washington, about new guidelines that strongly recommend against the use of spinal injections for chronic pain - and why that recommendation might be hard for some patients and doctors to hear.   Finally, we revisit the progress made in addressing racism in UK medical schools over the past five years with Gareth Iacobucci, The BMJ's assistant news editor.   Running order 01:44 Defining Misinformation and Disinformation 04:08 Vaccines and Misinformation 05:38 Strategies to Combat Disinformation 10:04 Denialism and Its Implications 16:21 BMJ Rapid Recommendations on Spinal Injections 26:27 Racism in Medical Schools: An Update   Reading list Spinal interventions for chronic back pain Racism in medical schools: are things improving?
