The Association between COVID-19 Status and Economic Costs in the Early Stages of the COVID-19 Pandemic: Evidence from a UK Symptom Surveillance Digital Survey

Introduction In the absence of a vaccination programme, the coronavirus disease 2019 (COVID-19) pandemic had substantial impacts on population health and wellbeing and health care services. We explored the association between COVID-19 status, sociodemographic, socioeconomic and clinical factors and economic costs during the second wave of the COVID-19 pandemic. Data The study used patient-reported digital survey and symptom surveillance data collected between July and December 2020, in collaboration with a primary care computerised medical record system supplier, EMIS Health, in the UK. The study included 11,534 participants. Methods Generalised linear models (GLM) and two-part regression models were used to estimate factors associated with economic costs (£sterling, 2022 prices) estimated from two perspectives: (i) a UK National Health Service (NHS) and personal social services (PSS) perspective and (ii) a societal perspective. Results Experience of the onset of COVID-19 symptoms started more than 3 months ago was associated with significantly higher NHS and PSS costs (GLM: £319.8, two-part: £171.7) (p < 0.001) and societal costs (GLM: £776.9, two-part: £675.6) (p < 0.001) in both models. A positive test result within the previous 14 days was associated with significantly higher NHS and PSS costs (two-part: £389.1) (p < 0.05) and societal costs (GLM: £470.7, two-part: £439.2) (p < 0.01). Age between 31 and 55 years was associated with significantly higher societal costs than age between 16 and 30 years. Conclusion This study identifies and quantifies factors associated with the economic costs incurred during the second wave of the COVID-19 pandemic in the UK. The results of our study can inform cross-country comparisons and other cost comparisons.
