Study participants were enrolled from Nov 2020 to Feb 2021. So probably before the delta and omicron variants. Outpatients were assigned either to a “standard program” of home monitoring or the standard program + pulse oximetry. There was no difference between groups in terms of “number of days alive and out of the hospital.” For the 30-day trial, that number was 29.4-29.5. In other words, very few of the ~1000 enrolees got very sick.
The standard program was “COVID Watch, a 2-week program involving twice-daily automated text messages inquiring about dyspnea and offering rapid callbacks from nurses when appropriate. This program has been associated with improved survival as compared with no remote monitoring.5“
I spent about 10 mins trying to find the age of these patients. No luck. I don’t even now if they were adult. Thanks, NEJM. I’m not totally convinced that outpatient oximetry has no role in home treatment of COVID-19. But clearly not every patient needs it. Perhaps just those at high risk of hospitalization and death.
