Black and brown patients have experienced disproportionately poorer outcomes from COVID-19 infection as compared with white patients. This study found that patients who identified as Asian, Black, or Hispanic may not have received timely diagnosis or treatment due to inaccurately measured pulse oximetry (SpO2). These inaccuracies and discrepancies should be considered in COVID outcome research as well as other respiratory illnesses that rely on SpO2 measurement for treatment.

The Joint Commission recognizes potential overuse of diagnostic imaging, particularly computed tomographic (CT) scans, to be a patient safety risk due to excess radiation exposure. This study sought to determine whether low-dose whole-body CT (WBCT), which exposes the patient to less radiation, has similar accuracy to standard-dose WBCT. A cohort of over 1,000 patients with suspected blunt trauma were prospectively recruited; half received standard-dose WBCT and the other half received low-dose WBCT.  The authors found that use of low-dose WBCT did not increase risk of missed injury diagnosis, while reducing median radiation exposure by almost half.
