  • EBST in the ED or during inpatient stay. For no admission with EBST, patients were either discharged from the hospital or admitted without EBST.

  • a Mean (± SD).

  • b For every 1-mo increase in age, the odds of admission with EBST decreased by 10%.

  • c For every °C increase in temperature, the odds of admission with EBST increased by 20%.

  • d N (%).

  • e For every 5 breaths per minute increase in respiratory rate the odds of admission with EBST increased by 30%.

  • f For every 1 % decrease in saturation, the odds of admission with EBST increased by 33%.
