Additional evidence from New York City showing that patients delayed care during the COVID-19 spring 2020 wave:
COVID-19 doesn't cause severe symptoms on the day of infection - like any other infectious disease, it takes time for the disease to progress.
"The four clinical outcomes considered were as follows:
Dead on arrival (DOA):
if the patient arrived in cardiac arrest with high suspicion of COVID-19 and was unable to be resuscitated.
Died in ED (DED):
the patient did not survive ED resuscitation attempts.
Died as an inpatient/died in hospital (DIH).
Survived to hospital discharge...
...Sub-cohort analysis based on primary patient disposition was also considered...
...We found that within this cohort, male sex, advanced age, a history of coronary artery disease, the non-respiratory findings of lactic acidosis, elevated D-dimer, and CKD/AKI were correlated with death either in the ED or during the patient's hospital course.
Fever, hypotension, and even initial respiratory status (including our analysis of the pre and post Sp02 [the Sp02 delta]) were not strongly correlated with outcomes
(likely because of the fact that all patients were severely hypoxic on arrival)."
