No Intervention: Control
Only remote monitoring
|
- Hospitalization/death [ Time Frame: 28 days ]Time to first hospital admission or death
- Recovery [ Time Frame: 28 days ]To assess the effectiveness of early treatment with dexamethasone in reducing time to recovery inpatients who are carefully monitored by their GP after a consultation for deteriorating COVID-19
- Disease severity [ Time Frame: 28 days ]To assess the effectiveness of early treatment with dexamethasone in reducing COVID-19 disease severity in patients who are remotely monitored by their GP after a consultation for deteriorating symptoms
- HCRU [ Time Frame: 28 days ]To assess the effectiveness of the intervention in reducing healthcare resource utilization (HCRU)

OR
- SpO2<92% (<90% for COPD patients) in rest with GP's and patient's shared decision to keep patient at home despite this in itself being an indication for referral to hospital
Exclusion Criteria:
- Inability to understand and sign the written consent form
- Inability to perform saturation measurements or sit-to-stand test
