EMRG medium-term projections for COVID-19 hospitalisations and deaths: 25 May 2022
Updated 6 January 2023
The UK Health Security Agency (UKHSA) Epidemiology Modelling Review Group (EMRG) shares these medium-term projections (MTPs) for coronavirus (COVID-19) hospitalisations and deaths with thanks to SPI-M-O, who contribute model outputs for the combined projections (not all modelling groups produce projections for both hospitalisations and deaths).
Medium-term projections
-
These MTPs for COVID-19 hospitalisations ± and deaths ¥ are not forecasts or predictions. They represent a scenario in which the trajectory of the epidemic continues to follow the trends that were seen in data available to 23 May 2022.
-
Several modelling groups produce their own set of projections. These individual projections are then combined to form consensus MTPs. MTPs are provided for England, Wales and Scotland, for hospital admissions (Figure 1) and deaths (Figure 2), as well as English regional hospital admissions (Figure 3) and deaths.
-
The number of deaths has fallen to very low levels in Scotland, Northern Ireland, Wales and in the English regions. Projecting forwards is difficult when numbers fall to very low levels, therefore projections for deaths are not provided for these nations and regions this week. However, the consensus view is that the number of deaths in these nations and regions will remain low over the next 6 weeks.
-
The delay between infection, developing symptoms, the need for hospital care, and death means the MTPs cannot fully reflect the impact of policy and behavioural changes made in the 2 to 3 weeks prior to 23 May 2022. An assumed effect of school holidays has been included.
-
Modelling groups have used their expert judgement and evidence from UKHSA and other published studies when making assumptions about vaccine effectiveness.
-
Projections do not include the potential effects of any novel variants. The delay between infection, developing symptoms, the need for hospital care, and death means it is unlikely that a novel variant will significantly alter the trajectories of hospitalisations and deaths in the timescales covered by these projections.
± These are new hospitalisations per day which incorporates both the number of individuals admitted with COVID-19, as well as inpatients newly diagnosed with COVID-19. Data definitions differ slightly across all 4 nations.
¥ These are the number of new deaths per day (by date of death) that are within 28 days of being identified as a COVID-19 case. Data definitions differ slightly across all 4 nations.

England
Number of patients admitted with confirmed COVID-19 and the number of inpatients diagnosed with COVID-19 in the past 24 hours. Taken from NHS England COVID-19 situation reports.
Wales
Number of patients admitted with confirmed COVID-19 by admission date and inpatients diagnosed with COVID-19 by test authorisation date. Provided by Public Health Wales. This figure has minor adjustments for publication to prevent statistical disclosure.
Scotland
Number of patients who tested positive for COVID-19 in the 14 days prior to admission, on the day of admission, or during their stay in hospital. Readmissions within 14 days of a positive test are excluded. Provided by Public Health Scotland. This figure has minor adjustments for publication to prevent statistical disclosure.
Northern Ireland
Number of patients admitted with confirmed COVID-19 and inpatients diagnosed with COVID-19. Provided by Health and Social Care Northern Ireland. This figure has minor adjustments for publication to prevent statistical disclosure.
England
The number of COVID-19 deaths (by date of death) within 28 days of being identified as a COVID-19 case. The past data for England is taken from the UKHSA line list of deaths. This figure has minor adjustments for publication to prevent statistical disclosure.
