Objectives
To quantify healthcare resource utilisation (HCRU) and costs to the National Health Service (NHS) associated with acute COVID-19 in adults in England.
Design
Population-based retrospective cohort study, using Clinical Practice Research Datalink (CPRD) Aurum primary care electronic medical records linked when available to Hospital Episode Statistics (HES) secondary care administrative data.
Setting
Patients registered to primary care practices in England.
Population
1,706,368 adults with a positive SARS-CoV-2 PCR or antigen test from August 2020 to January 2022 were included; 13,105 within the hospitalised cohort indexed between August 2020 and March 2021, and 1,693,263 within the primary care cohort indexed between August 2020 and January 2022.
Main outcome measures
Primary and secondary care HCRU and associated costs during the acute phase of COVID-19 (≤4 weeks following positive test), stratified by age group, risk of severe COVID-19 and immunocompromised status.
Results
Among the hospitalised cohort, average total length of stay, as well as in critical care wards, was longer in older adults. Median healthcare cost per hospitalisation was higher in those aged 75 – 84 (£8,942) and ≧85 years (£8,835) than in those aged <50 years (£7,703). Whilst few (6.0%) patients in critical care required mechanical ventilation, its use was higher in older adults (50 – 74 years: 8.3%; <50 years: 4.3%). HCRU and associated costs were often greater in those at higher risk of severe COVID-19 when compared to the overall cohort, although minimal differences in HCRU were found across the three different high-risk definitions implemented. Among the primary care cohort, GP or nurse consultations were more frequent among older adults and the immunocompromised.
Conclusions
COVID-19 related hospitalisations in older adults, particularly critical care admissions, were the primary drivers of high resource use of COVID-19 in England. These findings may inform health policy decisions and resource allocation in the prevention and management of COVID-19.
