Most practices have moved to total triage at a time when demand is low compared to normal. So, the system has to be set up to be able to manage when demand increases.
People often have a fear that demand is infinite and therefore unsustainable to manage, which is where using data to inform planning can really help. Any significant changes in ways of working can be challenging. Open discussion about concerns, challenges, success and benefits of the new systems will enable teams to refine and improve their system in a way that appreciates and develops the skills of the wider team.
