A study led by Johns Hopkins University researchers suggests that the use of pulse oximeters in hospitalized COVID-19 patients often overestimated true arterial oxygen saturation (SaO2), especially in those of minority race, and led to delayed therapy in a high proportion of patients of all races.
Average patient age was 63.9 years, 41.9% were female, 41.4% were white, 32.2% were Hispanic, 16.0% were Black, and 10.4% were Asian, Native American or Alaskan Native, Hawaiian or Pacific Islander, or another race.
, leading to a greater risk of occult hypoxemia, generally defined as a true arterial oxygen saturation below 88% with an oxygen saturation by pulse oximetry in a normal range above 92%," the study authors wrote.for Black , Hispanic , and other race patients compared with white patients. In the patient subset, compared with white patients, Black patients were at significantly higher risk of having pulse oximetry measurements that masked the need for COVID-19 medication .
Of note, Black patients had the lowest rate of in-hospital death and the shortest length of hospital stay. Pulse oximeter inaccuracy was highest among patients of minority race, suggesting that these groups would be disproportionately affected on a, but about 13% of patients who had occult hypoxemia and over 43% of patients with an unrecognized need for COVID-19 medication by pulse oximetry were white.

Study of children with COVID-19 suggests treatment differs by ageA large international team of medical researchers has found that the severity of COVID-19 infections in children over the course of the pandemic varied by age and viral variant. In their study, reported in the journal JAMA Pediatrics, the group analyzed clinical data for 31,785 children hospitalized due to COVID-19 infections from January 2020 to March 2022.

Study finds severe COVID-19 twice as common among bus driversBus drivers were at double the risk of being hospitalized for severe COVID-19 in the later stages of the pandemic, and several occupations in education and health care were also at risk of serious illness. This has been shown by a study at the University of Gothenburg published in the Scandinavian Journal of Work, Environment & Health.

Small study suggests long COVID may affect more people than previously thoughtMillions of Americans were exposed to SARS-CoV-2, the virus that causes COVID-19, early in the pandemic but could not get diagnosed due to testing limitations. Many of those people developed a post-viral syndrome with symptoms similar to those of long COVID. In a new study of a small group of those people, their immune response shows that 41% had evidence of SARS-CoV-2 exposure. The study is published in Neurology Neuroimmunology & Neuroinflammation.
