Patients were not screened for VTE but underwent investigations however, the risk is considered to be low because the majority are a local population who would re-present to Oxford with complications, and additionally, we have an established network with surrounding hospitals for informing us of post-discharge VTEs as part of the national VTE prevention programme [13, 14] . In summary, this report highlights the lack of data to guide VTE prevention strategies for hospital-led COVID-19 virtual wards. A strategy of 7 days thromboprophylaxis was associated with relatively low VTE rates and no major bleeding in this cohort of patients considered at risk of deterioration. It highlights the need for further data, including future prospective RCTs of VTE prevention in this expanding setting of hospital-led ambulatory care.
