COVID-19 Risk Assessments for UK National Health Service (NHS)

The UK’s national health service was in need of swift risk assessment processing during a period of challenging and unpredictable circumstances.


When COVID-19 lockdowns hit the UK in March 2020, over 25% of healthcare staff were selfisolating. The UK healthcare industry experienced significant resource shortages during a period of high demand.

All staff needed to be risk assessed within a month – a feat that had never before been attempted, and the service was poorly equipped.


In collaboration with a leading Occupational Health expert, a Rainbird knowledge map was created that combined government and published medical guidance on rapidly changing COVID-19 risk factors.

Together, they published the model with a web front-end that enabled any front-line worker to complete a comprehensive risk assessment that was confidential and ethically sound. The assessment produced accurate results, even with ambiguous and incomplete data.


Completed and deployed within just 8 days, the Rainbird-powered tool provides staff with digital, automated reports and has been deployed across health institutions in the UK.

Even now, in post-vaccine conditions, the healthcare provider still utilizes the Rainbird tool and is exploring several different use cases for Rainbirds’ other automation solutions.

Where to next?

The COVID-19 risk assessment concept can revolutionize decision-making within healthcare settings.

There are plans to create additional tools to: Reduce harm by prioritizing patients on long waiting lists. Design sustainable care solutions for special needs.
