Just half of shut contacts given to England’s NHS Test and Trace are being reached in some areas, a BBC investigation has discovered.

Six months after Boris Johnson promised a “world beating” system, it may be proven the community is failing in areas with a number of the worst an infection charges.

The analysis additionally discovered no-one from NHS labs was at a key authorities assembly with personal companies about testing.

But the federal government stated the system was “undoubtedly” curbing Covid spreading.

It added that NHS Test and Trace was coping with rising numbers of instances and was working arduous to “refine and improve” the way in which it labored.

The corporations and their leaders concerned with testing had “hundreds of years” of expertise within the discipline, it stated.

As ministers battle to get the test-and-trace system on monitor, BBC News spoke to key authorities figures, scientists and well being officers who had been concerned from the very begin to set up what went unsuitable with the system – and, crucially, whether or not the system could be mounted to carry the virus in examine till vaccines come to the rescue. The investigation discovered a system that’s failing within the areas the place it’s wanted essentially the most and remains to be undermined by the legacy of choices they had been made on the outset.

Further revelations embody:

  • Private contractors overpromised what they may do, with one saying it will construct 200 testing machines that hadn’t, on the time, even made it to prototype
  • The transfer to extra native contact tracing by councils was being undermined by IT issues, resulting in a reliance on spreadsheets and delays getting contact particulars.
Short presentational grey line

The identify NHS Test and Trace seems like it’s one complete service that’s a part of the NHS. Nothing might be farther from the reality.

It is a fancy internet of various programmes which have been bolted collectively quickly. Private companies play a key position by way of each testing and tracing, which has meant a number of the native experience obtainable within the NHS, universities and councils has been bypassed.

The seeds for this had been sown again on 17 March earlier than the primary lockdown was introduced when a gaggle of corporations met with authorities to debate testing.

That assembly included now-key gamers Randox and ThermoFisher, two health-technology companies. But no representatives talking for the present NHS labs sector had been concerned, says Allan Wilson, president of the Institute of Biomedical Science. “There wasn’t any consultation with the service itself.”

Very rapidly the route of journey grew to become clear – the federal government turned to its business companions to arrange massive, centralised labs that sat outdoors any current healthcare or analysis buildings.

There is now a community of six massive mega-labs – referred to as Lighthouse labs – that course of the majority of the exams throughout the UK. Testing websites, the place the swabs are taken, are run by the auditors, Deloitte.

The companies involved in Test and Trace

An identical resolution was made with contact tracing – a nationwide military of 18,000 contact tracers taken on by outsourcing firm Serco, whereas Sitel runs the contact centre. This component simply covers England. The remainder of the UK has its personal preparations.

The authorities stated whereas the contracts had been awarded underneath “extreme urgency brought about by unforeseeable events” they had been nonetheless achieved in accordance with strict situations.

But these near the decision-making on the time have considerations. “These contracts were signed and sealed in record time – there weren’t even penalty clauses inserted for performance in many,” says one supply concerned. “The government was in a panic – we were in the middle of lockdown and they were under pressure from all angles. It is not the environment in which the best decisions are made.”

The centralised system that bypassed native abilities

The authorities has now received a big testing capability – it could actually course of greater than 500,000 virus exams a day. At the beginning, the UK may solely do 2,000. But the system has struggled to shorten the time it takes from somebody being swabbed to getting a consequence.

“If we’d kept it local we would have been able to turn those tests around much quicker,” says Mr Wilson, referring to the present community of hospital, college and Public Health England labs. “We already had the logistics in place.”

Instead, a wholly new system needed to be set as much as get the samples into the Lighthouse labs, with swabs travelling lengthy distances – generally by aircraft from Edinburgh to Belfast – slowing down the method to this present day.

Dr Rachael Liebmann, vice-chair on the Royal College of Pathologists, who works in each personal and NHS labs, says: “The default was to go outside the NHS for something new and shiny. But there was not enough input from people who understood testing.”

According to Allan Wilson, the federal government was “speaking directly to the commercial companies and saying – what can you do for us?” There was no voice of problem, “saying ‘that won’t work'”.

Randox – which gained nearly £500m of contracts from the Department of Health – deliberate to recruit 200 new workers to assist ramp-up Covid-19 testing. It stated the corporate can be constructing 200 testing machines over the next six weeks. At this stage, although, its makers had not but accomplished a single completed prototype of the machine, and had beforehand anticipated they’d finally have the ability to construct about 10 a yr, the BBC understands. By September, not a single machine had been completed. The workers that had been recruited to construct them would usually be despatched residence or had been left sitting round.

A Randox spokesperson stated the agency had “not only met but exceeded all government programme expectations. In fact, Randox processes more samples than any other laboratory in the UK.”

Meanwhile, different corporations had been promoting testing machines to NHS-run labs which did testing for hospitals. This was regardless of the very fact the kits and chemical substances wanted for these machines had been in brief provide and being snapped up by the privately-run Lighthouse labs.

“There are labs that bought… equipment and still are not able to run them at capacity due to a lack of reagents [chemicals needed for testing],” Dr Liebmann says.

Hitting the goal however lacking the purpose?

The authorities’s obsession with hitting testing targets has additionally been closely criticised. First 10,000 exams a day by the top of March, then 100,000 a day by the top of April, earlier than a goal for capability of 500,000 a day by the top of October. But there was much less focus about who ought to get these exams and why.

Despite common recommendation to take action, folks working in hospitals weren’t screened for coronavirus until that they had signs. This has solely simply began taking place, regardless of proof displaying important transmission in hospitals. But there have been labs that did arrange common screening for healthcare workers of their very own accord – regardless of being “effectively discouraged” to take action, in accordance with one supply.

The University of Cambridge was one instance, its analysis lab partnering with close by Addenbrooke’s to supply screening to its hospital workers on the peak of the UK epidemic’s first wave. By the top of June it had screened greater than 10,000 folks working within the hospital, to detect asymptomatic carriers, says Dr Stephen Baker, who was concerned in creating the programme.

“It had a really big impact on keeping the hospital going,” and, he believes, helped give NHS workers some sense of security and morale.

September – the second testing fell over

Many of the problems with testing performed out behind the scenes. But they got here underneath acute public scrutiny in September when exams grew to become near-impossible to entry – simply in the mean time the second wave was taking off.

Part of this was pushed by people making use of for exams on return from holidays, and kids going again to high school. But there have been additionally problems with capability within the labs themselves. One volunteer in a Lighthouse lab, a virologist who wished to stay nameless, advised the BBC provide chain points slowed progress: “We would never know how many samples were going to come in. We had a forecast each day but they were never right.”

This meant generally having sufficient workers to course of 10,000 samples and solely receiving 2,000, leaving folks sitting round, and on different events receiving many greater than anticipated and struggling to take care of them.

While scientists had been concerned in establishing the labs, they weren’t essentially folks “who had any idea how to deal with viruses”, which means “procedures were constantly tweaked” and there have been points with recruitment and coaching which once more slowed issues down.

Why tracers must make a number of calls to households

Testing is one a part of the equation for holding coronavirus. Every bit as necessary is the power to hint shut contacts of these contaminated, guaranteeing they isolate at residence. For the tracing service, which went dwell on the finish of May, only a week after the prime minister’s world beating promise, issues have performed out in several methods.

It causes an enormous quantity of stress – lots of contact employees are upset as a result of they get lots of abuse about it

Test-and-trace supervisor

About 18,000 contact tracers had been employed – solely about 3,000 of them got here from a medical background.

That in itself was not essentially a problem. Those concerned within the service say the individuals who get the most effective outcomes are the nice communicators. The downside is that so usually the centralised name centre-based method didn’t allow them to talk. Contact tracers had been advised to comply with closely scripted cues.

There was no room for discretion. It has led to the scenario whereby name handlers must attempt to make particular person calls to each member of a family and undergo the identical kinds. This is a part of the explanation some households have discovered themselves receiving plenty of calls. It is within the strategy of being scrapped.

One test-and-trace supervisor advised the BBC it has undermined the system all through. “It causes a massive amount of stress. A lot of contact workers are upset because they get a lot of abuse about it.”

Failing within the areas that want it essentially the most

Overall, efficiency has fallen in need of what was hoped for. To be efficient, authorities advisers say 80% of people that take a look at optimistic ought to be reached and particulars of their shut contacts – mainly household, pals and work colleagues – obtained. Then 80% of these contacts must be reached and requested to isolate. In some areas simply half of shut contacts are being reached and requested to isolate. A quantity are within the areas with the very best charges, akin to Bradford, Manchester, Blackburn and Nottingham.

Performance by local area

The targets are reasonably broad brush. For one factor they ignore the truth that the testing system is routinely failing to establish about half of instances. The blame for this can’t be laid solely on the federal government – with so many contaminated folks not displaying signs, the system is up in opposition to it from the beginning. But with the targets missed nearly each week, it rapidly grew to become clear there was an excessive amount of deal with the nationwide system and never sufficient on native.

Has Dido Harding being unfairly maligned?

Much of the criticism has been geared toward Baroness Dido Harding, who was recruited to go up NHS Test and Trace. However, this was solely as soon as the contracts had been signed and the mannequin of working established. Working with what she has, she is adamant her staff have carried out nicely, frequently stating that regardless of the issues the service remains to be doing higher than these in lots of different international locations.

She says a system as “complex as Tesco” with its community of shops, distribution centres and provide chains has been in-built a matter of months.

You cannot anticipate test-and-trace by itself to maintain on high of the virus

Baroness Harding

“It will keep improving,” she says. “But you can’t expect test-and-trace on its own to keep on top of the virus – it is just one part of a wider approach.”

Comparing efficiency globally is tough. Many don’t publish the detailed data that England’s service does. Even the information supplied in the remainder of UK is extra restricted by comparability – though it suggests these techniques have struggled too. But some international locations have fared higher – Germany and South Korea, for instance. The Health Foundation says the secret’s these international locations’ larger emphasis on native groups.

Local councils ‘given hospital move’

The want for larger native involvement was really recognised by the federal government again in the summertime. On 10 August, ministers introduced they had been altering tack and the nationwide contact tracing staff can be lower by 6,000. Staff had been to be made obtainable to councils to permit them to arrange native groups which may tackle duty for tracing instances after the primary 24 hours. It adopted the success seen in a small handful of areas that had determined to arrange their very own native contact tracing groups.

The announcement by authorities was broadly welcomed by administrators of public well being, however then nothing occurred. It was not till late October that ministers got here up with an additional £1bn for the winter. This has been a supply of giant frustration. Councils had been calling for extra involvement from the beginning.

And as native schemes have gotten going – over a half have companies up-and-running now – they’ve confronted difficulties due to the centralised nature of the system. Among the issues reported are:

  • Delays getting instances handed down from the nationwide staff
  • Cases which might be handed on are lacking key contact data or are duplicates of instances already traced, losing precious time
  • Lack of entry to the central IT system utilized by NHS Test and Trace, which means councils are having to file the data they accumulate on spreadsheets
  • Councils are solely allowed to hint the contaminated case – leaving them powerless to take care of relations, for instance, even when they’re on the door-step

“It’s a complete nightmare,” says one public well being guide who has arrange a service. “We’ve been given a hospital pass. They never thought about using the local teams so the infrastructure isn’t there.”

Isolation – the forgotten a part of the test-and-trace system

While £10bn was put aside for test-and-trace to assist them discover people, it appears little or no thought was given to how folks ought to be supported to isolate. The quantity isolating each after a optimistic take a look at or as a result of they’re an in depth contact, isn’t routinely measured. Some analysis has recommended it could be as little as one in 5, however NHS Test and Trace has put the determine at near half. Either approach, it’s a obvious challenge. A number of have argued the isolation interval is just too lengthy.

Some different international locations solely require seven days’ isolation for shut contacts, says Prof Tim Spector, who runs the favored C-19 symptom tracker app. “More reality and pragmatism is now needed to keep people on-side,” he says.

On high that, there are questions on monetary help for individuals who cannot work whereas isolating at residence. Until late September there was none past statutory sick pay. Now there’s a one-off £500 cost for folks on advantages. People who’re requested to isolate by way of the app are usually not even entitled to this. Contact tracers the BBC spoke to say that is inflicting issues. “When we do get through, people are often uncooperative. They have lives to get on with and work they have to do to get paid.”

Prof Robert West, from University College London’s public well being division, believes this is among the most necessary points with the entire system.

“We need to do much more to help – then we can create strong social norms that it would be unthinkable to violate.”

The downside, although, he says, is we now have missed the boat. With infections excessive, the window for getting this proper has gone. “If introducing lockdown late was our biggest mistake in the first wave, in the second it is the fact we wasted the time that lockdown bought us to get an effective test-and-trace system running.”
