Reduction of the time taken between a positive test and the first clinical assessment—that must be another key performance indicator (KPI). As we're assessing the system, as we're assessing contact tracing—that should be a KPI. Give it a number, something that people can be accountable for. From your positive test to the time you're first called for a clinical assessment it should be this, and then report it. Put it out in the public domain. Be transparent with it, so we can all hold ourselves accountable.
