New co-host Liz Farah joins the RCEM Learning Podcast to discuss topics such as overnight boarding of older patients in the ED, use of opioids for back pain, management of hypertension in the ED, and investigation of cauda equina syndrome. They also explore the impact of long waiting times on patient outcomes, guidelines for hypertensive crisis, and the introduction of an interactive pathway tool. The Opal Trial study reveals that there is no evidence to support the prescription of opioids for acute back pain. Additionally, they discuss the role of the RSI assistant in the ED and provide insights on Bifascicular Heart Block.
