In April 2021, a team at the University of Nottingham announced its findings on healthcare workers treating hospitalised patients.
It found that black healthcare workers treating hospitalised patients during the first wave of the pandemic were more likely to have had coronavirus infections than their white counterparts.
This was true even when factors like age, sex, socioeconomic background and job role were taken into account.
The study combined data from:
- PANTHER, a UK Research and Innovation (UKRI) – funded study, based at the University of Nottingham and Nottingham University Hospitals NHS Trust
- COVIDsortium, a London-based study looking at workers at Barts Health and Royal Free NHS Trusts, working with colleagues from Queen Mary’s University and University College London.
A better evidence base to save lives
The disproportionate COVID-19 death rate among people from Black, Asian and minority ethnic backgrounds was established by mid-July 2020.
UKRI and the National Institute for Health Research (NIHR) identified this as an urgent area of focus. Six projects were funded to understand the links between COVID-19 and ethnicity and mitigate their impact.
At the time, Chief Medical Officer for England and Head of the NIHR, Professor Chris Whitty, said:
With evidence showing that people from Black, Asian and minority ethnic backgrounds are more severely affected by COVID-19, it is critical that we understand what factors are driving this risk to address them effectively.
UKRI Chief Executive, Professor Dame Ottoline Leyser, said:
There is unlikely to be a simple answer and we must consider all possibilities, reflected in the range of projects we have funded, so that we can save as many lives as possible during this pandemic and any future outbreaks.
The projects funded by the NIHR and UKRI is examining this association in detail, so that new treatments and approaches to care can be developed to target the ethnicities most at risk. This research will have embedded patient and public involvement with Black, Asian and minority ethnic groups at all stages of the research.

UK-REACH (UK Research Study into Ethnicity And COVID-19 outcomes in Healthcare workers) is calculating the risk of contracting and dying from COVID-19 for ethnic minority healthcare workers. It has access to over two million healthcare records held by national healthcare organisations.
The study includes non-clinical staff integral to the day-to-day running of healthcare institutions including cleaners, kitchen staff and porters. It is following a group of healthcare workers from Black, Asian and minority ethnic backgrounds over 12 months to see what changes occur in their physical and mental health.
A smaller group of healthcare workers are being interviewed to understand the risks of their jobs, and how they have changed their professional and social behaviours in response to COVID-19.
The team has also organised a stakeholder group of national organisations to help conduct the research and provide evidence to policymakers so that decisions can be made in near real-time. The group includes:
- the General Medical Council
- the Nursing and Midwifery Council
- The General Dental Council,
- NHS Employers
- Black, Asian and minority ethnic professional associations.
Dr Robert Aldridge, UCL: £1.4 million
This project aims to better understand the impact of COVID-19 on minority ethnic and migrant groups and how to tackle it in community settings.
The study builds on ‘Virus Watch’. Funded by UKRI and NIHR to study 25,000 individuals across the country in a nationally representative household cohort, it monitored spread of the novel coronavirus across England. This funding enabled them to recruit 12,000 more people from minority ethnic and migrant groups.
Their symptoms are followed over time and subsets of participants receive antigen and antibody tests. Other factors being studied include:
- household transmission
- healthcare usage
- mental health
- economic impacts
The team is also using the Million Migrant Cohort study of healthcare and mortality outcomes in non-EU migrants and refugees to England since 2015. In collaboration with Public Health England, this will be linked with data on COVID-19 diagnosis and hospitalisation to determine:
- how often these groups are diagnosed, hospitalised and die with COVID-19
- how this is affected by their socioeconomic situation and pre-existing health conditions.
Professor Aftab Ala, Royal Surrey NHS Foundation Trust and Kings College Hospital, Honorary Professor at the University of Surrey: £371,000
This project is designing culturally relevant health messages for Black and South Asian groups and deliver these messages through specific and trusted communications channels.
The team is working alongside local, regional and national Black, Asian and minority ethnic community groups, community and faith leaders and public health and allied health professionals. They will co-produce written and visual aids, short films mainly for smartphone viewing and mobile apps.
It is hoped this will influence behaviours that reduce the transmission of COVID-19, such as perceived risks and susceptibility, proximity and social distancing, and infection control.
The information gained from the project will be shared with the Black and South Asian community, community leaders and policymakers including NHS England and Public Health England.
Professor Julia Hippisley-Cox at the University of Oxford and Dr Hajira Dambha-Miller at the University of Southampton: £327,000
This study will determine the risk of infection and death from COVID-19 in individual ethnic groups and explain why these differences might exist.
The team is combining over 40 million patient GP records across rural and urban areas of England to create one of the largest COVID-19 cohorts in the UK. They will describe patterns of COVID-19 disease and death according to ethnicity and use statistical modelling to understand these differences.
Professor Thomas Yates, University of Leicester: £126,000
This study uses the UK Biobank cohort, which has been linked to national COVID-19 data.
Using this dataset, the team is conducting statistical modelling to examine whether the increased risk of developing severe COVID-19 in minority ethnic groups is explained by differences in underlying health status, lifestyle behaviours such as physical activity. They are also examining environmental factors, including measures of social inequality.
This work will unpick why minority ethnic groups may be at increased risk and whether this increased risk is observed equally across the population. For example:
- is the increased risk explained by a higher burden of other diseases such as heart disease or diabetes or by living in more polluted or deprived areas?
- do otherwise healthy individuals from minority ethnic groups still have an increased risk?
Addressing these questions will help inform public health priorities and prevention strategies.
