In England, primary care provision is unequally distributed by socioeconomic status and ethnicity, as is prevalence of chronic disease, uptake of vaccination, and impact of infectious disease epidemics. These inequalities likely synergise resulting in unequal impacts on healthcare and patient health during epidemics of common winter-seasonal respiratory viruses. Through this collaboration with the London School of Hygiene and Tropical Medicine and the University of Oxford, we will generate a comprehensive examination of winter pressures in primary care in England, their consequences, predictability and potential mitigations, to help address underlying health inequalities arising from winter pressures.
