    What treatment?
    George Anstadt, MD | University of Rochester
    Please share how these folks were cared for. Many us us are engaged in the clinical practice of medicine. We are looking into the eyes of critically ill and dying patients, and need feedback even if it is not yet definitive. Will you please put a comment here for us?

    Thanks for sharing.
    Mortality rates by age group

    Thank you for this research. ICU by age group is presented, but not mortality. Also, comorbidities are listed, but not by age. Both are needed before drawing conclusions about age group risk.

    Coronavirus disease 2019 (COVID-19) has resulted in increased hospital and intensive care unit (ICU) use. In the United States, few reports have characterized patients treated outside of the ICU.1 Northern California was an early epicenter of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) community transmission in the United States. We report hospitalization and ICU admissions from Kaiser Permanente Northern California (KPNC), a regional integrated health care system serving 4.4 million members, constituting 30% of the area’s insured population.

    We performed a retrospective cohort study of adults (≥18 years) with nasal/throat swabs positive for SARS-CoV-2 by polymerase chain reaction hospitalized between March 1, 2020, and March 31, 2020, at 21 KPNC hospitals. Tests were approved by infectious disease physicians based on public health and local guidelines. Patients were triaged according to clinician judgment. No patients were lost to follow-up.
