Holyrood, Nicola Sturgeon and Patrick Harvie.
“Therefore, until yesterday, testing capacity was—my arithmetic might betray me here—about 6,350, so the figure of 4,000 tests represents use of more than 70 per cent of the capacity that we had yesterday. If I have, in the moment, got any of those figures wrong, I will happily correct them later.
“I also said on Friday—this is something about which my understanding has deepened over the past weeks—that there will never be a perfect match between capacity for testing and use of testing, because of fluctuations and geographical variations in demand.
“There will also never be a perfect match between the number of tests that we do and the number of people who are tested, because there are good clinical reasons why some people require to be tested more than once.
“For example, we require that Covid patients who are being discharged from hospital to a care home have two negative tests. There will always be differences.
“We are working to ensure that capacity is used as fully as is possible and practical, and we are working to build capacity beyond what it is now. The milestones that I set out were capacity for 10,000 tests by the end of this week, and for 12,000 by the middle of the month.
“The initial assessment of where we need to go after that, for TTI, is 15,500. Again, I will inject a bit of caution on that number: we might need to go beyond it. That will depend very much on how well we suppress the virus and on the requirement for testing to keep it at low levels.”
Patrick Harvie replied: “We will continue to look at the figures, of course, but the tables that were published yesterday seemed to suggest that there had been 1,400 or 1,600 tests done per day, from capacity for well over 8,000 a day.
“Mass testing—actual tests taking place, as opposed to capacity—is only the first element in TTI. It is good that the Scottish Government is emphasising the work of human contact tracers as the next step. A proximity app might well have a role to play, but I agree with the First Minister that it should not and cannot replace the proven methods that are used by people who work in public health.
“I was therefore pleased to see the first estimate of the numbers, which is that 2,000 contact tracers will be needed.
“However, the plan that was published on Monday does not have clear timescales attached to it, so I am still unclear about the timescale, even after the First Minister’s exchange with Jackson Carlaw [the Tory leader].
“The First Minister says that enhanced contact tracing capacity should be in place by the end of May. Does that mean that 2,000 contact tracers will be recruited, trained and deployed by then?
“If not, how many will be in place by then? Will the First Minister tell us who is undertaking that recruitment? Will the contact tracers be employed by public health agencies or by outsourced private contractors?
“What measures will be put in place to support people for whom isolation will pose particular challenges, including people with family caring responsibilities, significant disabilities or complex health needs?”
The First Minister shot back: “We will set out more detail on the milestones towards capacity, and we will set out changes to our estimates of capacity as we build towards milestones.
“Health boards are already looking to train existing staff in contact tracing, and an advert will go live on Friday, through Public Health Scotland, for recruitment of additional contact tracers.
“That work is under way. I ask members to try to appreciate the complexities in the assessments that are required to allow us to estimate what we need, and to appreciate that they will vary as we go through the experience of the pandemic. We will share as much detail of that information as we can, as quickly as possible.”
