Pragmatic RCT: In outpatients with Covid-19, the addition of pulse oximetry for monitoring did not improve outcomes compared to subjective assessments of dyspnea alone.

Pulse Oximetry for Monitoring Patients with Covid-19 at Home — A Pragmatic, Randomized Trial – New England Journal of Medicine

Commentary on Twitter

A potential practice changer by @kit_delgadoMD et al in NEJM today.

At-home pulse oximeters did NOT improve outcomes.

Important to focus on things that help.

If these devices don't help, then we shouldn't routinely advise them.

Super interesting work.https://t.co/VDDyRLw7ba
