Level	Description of clinical profile	Criteria for temporary hospital admission
Level 1	Patients with criteria for immediate ICU evaluation, O2 saturation ≤94% with mask-reservoir, respiratory rate > 30 rpm, hemodynamic instability, altered level of consciousness without other explanation and good baseline status.	Does not meet criteria
Level 2	Patient is a candidate for admission to the ICU if presents poor evolution, at the time of assessment has high oxygen therapy requirements, as well as analytical and radiographic factors of poor prognosis. Requires close monitoring and possible intensification of treatment.	Does not meet criteria
Level 3	The patient is not a candidate for admission to the ICU, presents high oxygen therapy requirements, as well as analytical and radiographic factors of poor prognosis. In case of complications or poor evolution, he would be a candidate for therapeutic deintensification guaranteeing palliative care (symptomatic and emotional control).	Meet criteria
Level 4	Patient at low risk of admission to the ICU due to clinical stability, regardless of baseline condition or prognosis unrelated to COVID infection.	Meet criteria
Level 5	Patients without hospital admission criteria	No admission required
