The latest analysis from Liverpool City Region’s Covid rapid test programme has revealed useful insights that will help policymakers, public health teams and the public.
The Covid rapid test drive by the city, known as the Covid-SMART community testing programme, was a national pilot of community open-access testing for the COVID-19 virus. It was coordinated by Liverpool City Region/ Merseyside Resilience Forum, NHS Test and Trace, Cheshire & Merseyside Health & Care Partnership and the University of Liverpool.
It was available to people with or without symptoms and provided Covid rapid testing programmes open to everyone living or working in the Liverpool City Region.
Covid rapid test programme results
The evaluation report, led by researchers from the University of Liverpool’s Institute of Population Health, found:
- A 32% reduction in Covid-19 hospitalisations – a larger effect than previously reported from synthetic control analysis following the release of more detailed national data.
- The ‘test to release’ scheme saved 8,292 key worker workdays. Workers used a daily negative lateral flow test (LFT) as a C-19 certification to work. 34 Covid-19 cases were identified – only three of these had been missed by daily LFTs.
- Test-to-release (also known as daily contact testing) is important for civic resilience – evidence needs to inform current (locally variable) policies.
Between December 2020 and July 2021, 668,243 (45%) Liverpool City Region (LCR) residents aged five years and older had registered results from SARS-CoV-2 with a Covid rapid test at one of the testing centres or via universal access home test kits.
Impacts recently reported from the City of Liverpool Pilot a month earlier included an 18% increase in case detection and a 21% decrease in case rates up to mid-December 2020 when Liverpool was more easily compared with other regions before the Alpha wave occurred. The current report covered the UK’s first roll-out of community rapid antigen testing in the wider Liverpool City Region (1.5m residents) from December 2020.
Professor Iain Buchan, Dean of the Institute of Population Health and lead for the evaluation of Liverpool community testing pilot, said: “This time last year, as the Alpha variant was surging, we found that Liverpool City Region’s early roll-out of community rapid testing was associated with a 32% fall in COVID-19 hospital admissions after careful matching to other parts of the country in a similar position to Liverpool but without rapid testing.
“We also found that daily lateral flow testing as an alternative to quarantine for people who had been in close contact with a known infected person enabled emergency services to keep key teams such as fire crews in work, underpinning public safety.
“As the more infectious Omicron variant sweeps through communities this winter, access to rapid testing will be important for keeping key emergency, social care and NHS services afloat with test-to-release or daily contact testing schemes.
“To make testing useful, communities need to understand how to use a test and what the results mean – timing is critical – you can become infectious very quickly, so taking a test the day before you mix with other people is not as useful as taking the test just before you meet up. The more you encourage those you mix with to ‘test before you go’, the more risk you will take out – this kind of crowd-sourced health security is the new normal.”
Community testing programme
The covid-smart community testing programme aimed to reduce or contain transmission of the virus whilst tackling the harms to health, social and economic wellbeing from COVID-19 restrictions.
The ‘SMART’ (Systematic, Meaningful, Asymptomatic/agile, Repeated Testing) approach had three components:
- ‘Test-to-protect’ vulnerable people and settings
- ‘Test-to-release’ contacts of confirmed infected people sooner from quarantine than the stipulated period
- ‘Test-to-enable’ careful return to restricted activities to improve public health, social fabric, and the economy.
Professor Iain Buchan said: “The single most important direct COVID-19 action anyone can take is to get vaccinated and to encourage friends and family who may have been infected with anti-vax misinformation to get vaccinated.
“Another important action is to use testing as directed by your local public health teams and workplaces, alongside wearing a face-covering wherever you can.
“The NHS is dealing with many pressures this winter, including COVID-19, and staff are exhausted – community action to slow the Omicron spread with testing and choosing not to mix outside your usual groups is an important way to help the NHS.”
